name: hidden-gems-researcher
description: |
  Discovers off-the-beaten-path experiences at travel destinations using a
  structured research and verification method. Produces a curated list of
  hidden gems with access instructions, timing recommendations, and crowd
  avoidance strategies. Use when the user asks about finding unique non-touristy
  experiences, discovering local secrets at a destination, avoiding tourist
  traps, or finding authentic local spots. Do NOT use for mainstream attraction
  planning (use cultural-experience-guide), general itinerary building (use
  trip-itinerary-builder), or restaurant-specific research (use
  food-tourism-planner).

# Hidden Gems Researcher

## When to Use

Use this skill when the user's request centers on discovering non-mainstream, authentic, or locally-oriented experiences at a destination -- not on building a complete itinerary or researching specific restaurants or hotels.

**Trigger scenarios where this skill applies:**
- The user is a returning visitor who has already completed standard sightseeing and wants a fundamentally different kind of trip to the same destination
- The user explicitly expresses frustration with tourist traps, overcrowded sites, or the manufactured feel of mainstream travel experiences
- The user asks about experiencing a destination "like a local" or discovering what residents actually do, eat, see, and value
- The user wants to visit a well-known destination but avoid the specific crowds, queues, and commercialized zones associated with it
- The user has limited time (1-2 days) in a city and wants to use it on something more rewarding than a checklist of famous sights
- The user is a slow traveler, digital nomad, or long-stay visitor who needs depth rather than breadth -- the kind of discovery that rewards multiple visits to the same neighborhood
- The user is an enthusiast of a specific niche (street art, industrial architecture, vernacular buildings, local sport, craft traditions, urban ecology) and wants to find where that niche lives in a given city

**Do NOT use this skill when:**
- The user needs a complete day-by-day travel itinerary -- use `trip-itinerary-builder` instead, which handles routing, pacing, accommodation proximity, and logistics holistically
- The user's primary goal is finding the best food, specific dish, or local dining culture -- use `food-tourism-planner`, which applies culinary-specific discovery methods including market research and neighborhood dining guides
- The user wants guidance on major cultural institutions, heritage sites, or UNESCO-listed attractions -- use `cultural-experience-guide`, which handles ticketing, context, and cultural interpretation for mainstream sites
- The user needs to book, schedule, or logistically plan an activity (tour times, gear rental, group size, safety briefing) -- use `adventure-activity-planner`
- The user is asking about travel safety, entry requirements, health advisories, or visa logistics -- those topics require different skill sets with up-to-date regulatory knowledge
- The user wants a simple "top 10 things to do" list -- this skill produces curated, research-backed discovery guides, not quick listicles

## Process

### Step 1: Gather Discovery Parameters

Before generating any recommendations, collect the following from the user. If the conversation already contains this information, extract it rather than re-asking. If critical information is missing, ask for it in a single consolidated question rather than multiple rounds.

- **Destination specificity:** City, region, or neighborhood? A user saying "Portugal" needs a different approach than "Lisbon's Mouraria neighborhood." Pin down the geographic scope before proceeding.
- **Prior exposure to the destination:** What has the user already done or seen? This prevents recommending the mainstream. Ask about previous trips, not just this itinerary.
- **Available exploration time:** Total trip length AND the amount of unscheduled time available for discovery. A 4-day trip with 2 days blocked for family obligations needs focused recommendations, not a sprawling guide.
- **Interest categories:** Probe for at least 2-3 specific categories from this taxonomy:
  - Built environment (hidden architecture, vernacular housing, industrial heritage, Art Nouveau, brutalism, sacred spaces not in guidebooks)
  - Community life (local markets, neighborhood festivals, community gardens, sports clubs, public libraries, town squares at dusk)
  - Craft and making (artisan workshops, printmaking studios, ceramics, tailors, bookbinders, instrument repair, food production)
  - Nature pockets (urban forests, canal paths, botanical garden sections, geological oddities, rooftop gardens, urban farms)
  - Underground and subterranean (catacombs, drainage infrastructure tours, basement galleries, wine cellars, bunkers)
  - Street culture (murals, independent record shops, zine libraries, skate spots, community notice boards as local maps)
  - Temporal experiences (early morning rituals, late-night local hangouts, seasonal phenomena, market days)
  - Institutional oddities (unusual museums, specialist collections, archives open to the public, academic collections)
- **Comfort and navigation profile:**
  - Navigation confidence: Uses transit fluently / needs clearly marked routes / prefers walkable from a fixed base
  - Language: Fluent or advanced local language / basic phrases / English only
  - Physical capability: High walking tolerance (8+ km/day) / moderate (4-6 km/day) / accessibility requirements
  - Risk appetite: Comfortable in unpolished neighborhoods / prefers areas with visible tourist infrastructure / safety-conscious
- **Group composition:** Solo traveler, couple, family with children, group of friends, multi-generational. This changes which gems are appropriate.
- **Budget orientation for experiences:** Some hidden gems involve small entry fees or purchasing something local; others are free. Note whether this is a constraint.

### Step 2: Apply the Six-Layer Discovery Framework

Do not simply list "lesser-known" places you associate with the destination. Instead, apply each of these six analytical lenses to generate candidates systematically. Strong hidden gem guides use at least three of these methods, ideally all six.

**Layer 1 -- Neighborhood Adjacency Method**
Every major tourist zone has an adjacent neighborhood that shares its character without its crowds. Map the tourist gravity wells (the areas where visitors concentrate) and then identify what lies one zone outward in each cardinal direction. In almost every city, this adjacent zone contains similar architecture, similar cafes, similar culture -- without the premium pricing, tour groups, or Instagram queues. Apply this method when the user is staying in or near a tourist core.

**Layer 2 -- Time-Shift Method**
The same physical location creates a fundamentally different experience at different times. A busy market square at 2 PM is tourist infrastructure; the same square at 7 AM is a working community. Identify time windows that shift the experience for already-known locations:
- Early morning (5:30-8:30 AM): Street cleaning, cafe ritual, local commute, morning light on facades, no tour groups
- Late afternoon (4:00-6:30 PM): "Golden hour" light, locals returning from work, aperitivo culture emerging, children in parks
- Weekday vs. weekend inversions: Some sites are busy weekends (tourist-oriented) but quiet weekdays; others are the reverse (local markets operate weekdays, closed weekends)
- Off-season timing: Shoulder season or low season transforms destinations -- Carnival without tourists, Christmas markets one day before opening when locals test them

**Layer 3 -- Vertical Exploration Method**
Most tourists experience destinations at ground level. Systematically look above and below street level for experiences invisible from the sidewalk:
- Upward: Rooftop terraces not marketed to tourists, upper floors of public buildings, belvedere viewpoints reached by stairs locals use, church bell towers open by appointment, apartment building terraces visible from higher adjacent streets
- Downward: Basement galleries, urban archaeology layers, wine cave systems, cisterns, drainage infrastructure tours (Paris catacombs are known; the equivalent in smaller cities often is not), subterranean passages connecting buildings
- Inward: Courtyards behind unmarked doors, library reading rooms, arcade passages (gallerias, passages, arcades) in European cities, building lobbies of interwar apartment blocks

**Layer 4 -- Purpose-Shift Method**
Places built for local function, not tourist consumption, offer the most authentic access. Map these categories for the destination:
- **Educational institutions:** University campuses, architecture faculty buildings, botanical gardens attached to universities, academic museums not listed in mainstream guides, lecture theaters with public events
- **Civic infrastructure:** Public libraries (often architecturally significant and open to all), city archives, municipal markets, fire stations with open days, water tower viewing platforms, cemetery walks (European cemeteries especially are often extraordinary sculptural landscapes)
- **Community organizing nodes:** Community centers, sports club grounds, neighborhood association halls, religious buildings used for community functions, cooperative shops
- **Working professionals' spaces:** Flower wholesale markets (visited at 4 AM by florists, open to public), fish auctions, livestock markets, printing districts, garment districts before they gentrify entirely

**Layer 5 -- Event Calendar Method**
Recurring and one-time events provide the most temporally specific hidden gem opportunities -- things that will only exist during the user's travel dates. Research:
- Weekly recurring events: Market days (not tourist markets -- the municipal market that serves residents), neighborhood sports matches, outdoor cinema seasons, community allotment open days
- Annual festivals: Local patron saint days, neighborhood festivals not listed in major tourism media, agricultural fair days, craft fair weekends, seasonal harvest events
- Monthly events: First Sunday museum free days, full moon events, monthly flea markets (distinguishing local secondhand markets from tourist antique fairs)
- Date-specific phenomena: Solstice light effects in specific buildings, blooming season for specific gardens, migration patterns visible from specific viewpoints

**Layer 6 -- Specialist Community Method**
Every city has enthusiast communities organized around specific interests -- and those communities know the city's hidden geography for their interest area better than any guidebook. Identify where these communities gather and what they recommend:
- Photography communities: Know viewpoints, light windows, and architectural details invisible to general tourists
- Urban exploration communities: Know industrial heritage, derelict spaces with open access, and infrastructure with public viewing options
- Running clubs: Know park networks, canal paths, and neighborhood routes not on tourist maps
- Architecture enthusiasts: Know which buildings have open courtyard access, which have public viewing platforms, which hold occasional open days
- Local history societies: Know which unremarkable-looking locations hold extraordinary historical significance

---

### Step 3: Verify and Qualify Each Candidate

Never include a candidate in the final guide without passing it through this verification filter. The quality of a hidden gems guide depends entirely on the integrity of this step.

**Accessibility verification:**
- Is the location still operating in the form described? Businesses close, museums relocate, markets move, buildings undergo renovation. Flag any candidate where you have uncertainty about current operating status and note that verification is advised.
- Is access genuinely public? Distinguish between: (a) fully public with no restriction, (b) publicly accessible but with specific hours or conditions, (c) accessible with advance contact or booking, (d) technically accessible but socially requires permission.
- Are there seasonal restrictions? Many locations are only accessible in specific months or have significantly different experiences by season.

**Crowding verification -- the "Overexposure Test":**
Apply this three-question test to determine if a candidate is still genuinely hidden:
1. Does it appear in the first two pages of any major English-language guidebook series for the destination? If yes, it is mainstream regardless of how it is framed.
2. Does it have more than 500 reviews on any major travel review platform? If yes, it has crossed the threshold from hidden to well-known -- it may still be worth recommending but must be framed as "lesser-known" not "hidden."
3. Has it been prominently featured in a major travel publication or popular travel social media content in the past 2 years? Viral "hidden gems" become overcrowded within months.

**Authenticity check:**
- Is the experience genuinely connected to local life, or has it been manufactured for tourist consumption while retaining a "local" aesthetic? Many "local markets" in tourist cities are entirely stocked with imported goods targeting visitors.
- Is the community welcoming of visitors, or would the arrival of tourists disrupt or commodify something that functions because it is undiscovered?

**Worth-the-effort check:**
- Does the experience justify the access difficulty? A 45-minute transit journey to see a mildly interesting building fails this test. A 45-minute journey to experience a neighborhood where nothing has changed in 60 years, including a morning coffee at a bar that has operated since 1952, passes it.
- For physical effort: Can you describe specifically what makes the experience rewarding enough to warrant the effort required?

---

### Step 4: Score Each Validated Gem

Rate every verified candidate on three dimensions using whole numbers 1-5. Use this scoring consistently so the guide communicates relative value clearly.

**Uniqueness Score (1-5):**
- 5: Virtually unknown to visitors; requires insider knowledge or this specific research to find; no mainstream coverage
- 4: Known in specialist travel circles or mentioned in one minor guidebook; not in mainstream awareness
- 3: Known to experienced travelers but not in typical tourist routes; may appear in "off the beaten path" sections of guidebooks
- 2: Well-known to travelers who research carefully; appears in multiple "hidden gem" style articles but not in core guidebook content
- 1: Commonly known but uncrowded for structural reasons (distance, accessibility, hours); not truly hidden

**Experience Quality Score (1-5):**
- 5: Genuinely transformative; creates a lasting memory; offers something unavailable anywhere else
- 4: Highly rewarding; significant emotional or aesthetic impact; strong sense of discovery
- 3: Worthwhile; a good experience that enhances understanding of the destination
- 2: Mildly interesting; worth including if convenient but not worth special effort
- 1: Only marginally notable; include only if no better alternatives exist

**Access Difficulty Score (1-5) -- note: lower is easier:**
- 5: Requires significant local knowledge, language skill, or unconventional navigation; may need advance arrangements; may be in an area with safety considerations
- 4: Off main transit routes; requires walking in unmarked areas or some language confidence; entrance not obvious
- 3: Reachable by transit with some navigation effort; entrance identifiable with advance knowledge of what to look for
- 2: Easy transit or walkable from central areas; entrance clearly identifiable; no language required
- 1: Extremely easy; visible from tourist routes or adjacent to known landmarks; zero barrier to access

**Composite Score Calculation:**
Uniqueness + Experience Quality + (6 -- Access Difficulty) = Accessibility-Adjusted Score (maximum 15)

**Threshold for inclusion:**
- Score 12-15: Core recommendation -- include with full detail
- Score 9-11: Secondary recommendation -- include with moderate detail or as a "pair with" addition
- Score below 9: Exclude unless no stronger alternatives exist and the user has a specific relevant interest

---

### Step 5: Create Precision Access Instructions

For each gem scoring 9 or above, write access instructions at the level of detail that would allow a first-time visitor to navigate there independently, without a guide and without already knowing the location exists. Vague directions are a failure mode in this skill.

Each access entry must contain:

- **Street-level navigation anchor:** Not just the neighborhood name, but a specific starting point (a named transit stop, a major intersection, or a known landmark) and walking direction and distance from that anchor. "10 minutes north of Piramide Metro station on Via Ostiense" is correct; "in the Ostiense neighborhood" is insufficient.
- **Visual identification cue:** What does the user look for when approaching? The color of a door, the presence of a specific sign, the courtyard visible through an arch, a specific building number. Many hidden gems have no signs whatsoever.
- **Operating conditions:** Days open, hours, whether entry is free or has a fee, whether booking is required. Note if seasonal variations apply.
- **Optimal visit window:** Not just "morning" but a specific time range and the reason. "Weekday between 8 and 10 AM because the market vendors are setting up and locals outnumber visitors by 10 to 1 -- after 11 AM, the demographic shifts."
- **Time allocation:** Minimum time to experience the gem meaningfully, and maximum time a thorough visitor would spend. "Allow 20 minutes minimum; 45 minutes if you linger in the back rooms."
- **Language provisions:** If any local language is required or significantly enhances the experience, provide the exact phrases in both the local language and a phonetic version. "Posso dare un'occhiata?" (PO-sso DA-re oon ok-YA-ta) -- "May I take a look?" opens many workshop doors.
- **Crowd patterns:** When is it at its most empty? When does crowding begin? Is there a specific day when it is reliably quiet? A weekday pattern vs. weekend?
- **What to bring:** Camera policy, cash requirements (many local vendors and artisans are cash-only), appropriate clothing for religious or community spaces, comfortable shoes for uneven surfaces, layers for underground spaces.
- **Respect protocol:** How to behave as a visitor in a community space. What signals indicate you are welcome to look, to photograph, to interact? What signals indicate you should move on?

---

### Step 6: Identify Tourist Trap Counterweights

Every hidden gems guide must include a "commonly recommended but disappointing" list specific to the destination. This serves two functions: it validates the guide's credibility, and it helps the user avoid wasting limited time on experiences that have been co-opted by tourist infrastructure.

The tourist trap identification criteria:
- **Price premium without quality premium:** A "local" experience priced at tourist rates for tourist volume -- the sign may say "traditional" or "authentic" but the operation is structured around visitor throughput, not local service
- **Manufactured authenticity:** A market, district, or "artisan" experience created entirely for visitor consumption, with no organic connection to local practice
- **Overexposed hidden gem:** A former hidden gem that has been profiled so widely it has become the new mainstream -- the "secret" beach now has a car park, ticket booth, and branded merchandise
- **Social media trap:** A location whose primary purpose has become providing a backdrop for photographs, with no substantive experience once the image is taken

For each destination, name 3-5 specific things commonly recommended as "hidden" or "local" that meet these criteria, and explain briefly why they fail the test.

---

### Step 7: Build the Exploration Schedule

Sequence the recommended gems into a practical exploration schedule that accounts for geographic clustering, transit logic, and timing requirements. Apply these scheduling principles:

- **Cluster by neighborhood:** Gems in the same district should appear in the same session. Transit time between gems erodes the experience.
- **Sequence by optimal time:** Time-sensitive gems (early morning markets, evening aperitivo spots, specific light conditions) anchor the schedule. Fill around them.
- **Build in discovery buffer:** Leave 30-45 minutes of unscheduled time in each half-day. The best hidden gem often reveals itself when you take a wrong turn while navigating to another one.
- **Pair high-effort gems with low-effort gems:** After a 45-minute commute to a remote neighborhood, the schedule should reward with multiple gems in that zone, not one.
- **Acknowledge transit transitions:** Specify the exact transit line, stop name, and approximate transit time for each segment. Vague instructions ("take public transit") are not actionable.

---

### Step 8: Add a Self-Discovery Appendix

Empower the user to continue finding gems independently during their trip. This section should not be generic advice about "talking to locals" -- it must be specific, actionable methods the user can apply in the field.

Include at minimum:
- The specific question to ask accommodation staff that generates useful insider recommendations (not "what should I see" -- that produces mainstream answers)
- How to read a neighborhood for authenticity signals (specific physical cues: the ratio of menus in local language vs. tourist languages outside restaurants; whether a bakery has a number ticket system indicating local use; whether a bar has a TV showing local sports)
- How to use local-language social media or community platforms (neighborhood Facebook groups, local community apps, city subreddits in the local language) to find events during the trip
- How to identify the neighborhood's social anchor (every neighborhood has one -- a square, a bar, a park bench cluster, a football pitch -- where residents actually spend time), and how to find it on foot

---

### Self-Discovery Method

**While in [Destination], use these specific methods to find additional gems:**

1. **The Accommodation Question:** Instead of "what should I see," ask your host: "[Specific question tailored to destination and host type]." This question bypasses the mainstream list because it asks about behavior, not recommendations.

2. **The Language Ratio Test:** Before entering any market, cafe, or "local" shop, read the signage. If more than one language appears on the main signage, the primary clientele is mixed tourist/local. If everything is in the local language only, you are in a genuine local establishment.

3. **The Neighborhood Anchor Walk:** On arrival in any new neighborhood, walk to the center of the residential zone (away from the main commercial street) at around 5-6 PM on a weekday. The location where residents gather -- a bench cluster, a fountain, a specific bar -- is the neighborhood's social heart. Observe from the perimeter before engaging.

4. **Local Event Discovery:** Search "[destination city] + [local language word for neighborhood/events] + [current month]" on the local-language version of social media platforms to find community events not listed in English-language tourism media.

5. **The Transit End Method:** Take any tram or local bus to its terminus. The neighborhoods at the ends of lines are almost always residential and rarely touristed. Walk back 3-4 stops through whatever you find.
```

---

## Rules

1. **Never recommend locations with fewer than clear public access confirmation.** If you cannot confirm that a location is genuinely publicly accessible (not merely technically visitable with social risk, trespass risk, or intrusion into private community space), exclude it. When in doubt, note "verify before visiting" explicitly.

2. **Apply the overexposure threshold rigorously.** Any location that has been prominently featured in a major English-language publication (print or digital) within the past two years should be framed as "lesser-known" at best, not "hidden." The discovery timeline of the internet means a viral "hidden gem" can absorb a year's worth of tourist visits in six months.

3. **Score every gem using the three-dimension system before including it.** Never skip the scoring step to save time. A gem that scores below 9 on the composite should not appear in the core recommendations regardless of how interesting it sounds in description. The scoring forces honest assessment of whether the experience justifies the effort.

4. **Provide street-level navigation, not neighborhood-level navigation.** "In the Navigli district" is not an access instruction. "Exit the Porta Genova FS station, cross Via Vigevano heading west, and walk along the Naviglio Grande canal for 400 meters until you see an unmarked wooden door with a brass bull-head knocker" is an access instruction. The difference is what determines whether the user finds the gem or gives up.

5. **Never fabricate operating details.** If you do not have confirmed information about opening hours, entry fees, or seasonal availability, say so explicitly -- "opening hours unconfirmed, verify before visiting" -- rather than inventing plausible-sounding details. Fabricated logistics cause real travel disruptions and destroy trust in the guide.

6. **Balance the guide's difficulty profile.** Every guide must contain at least two gems accessible with minimal effort (scoring 1-2 on access difficulty) alongside more challenging discoveries. A guide that requires adventurous navigation for every recommendation is inaccessible to most users and fails to serve families, older travelers, and those with accessibility needs.

7. **Write respect protocols that are specific and behavioral, not aspirational.** "Be respectful of local culture" is not a respect protocol. "Do not photograph market vendors or their stalls without making eye contact and receiving a nod of acknowledgment -- approach with a small purchase first" is a respect protocol. The difference is between a platitude and an instruction.

8. **Include the self-discovery method in every guide without exception.** The traveler will spend more time at the destination than the guide can anticipate. Empowering independent discovery extends the value of the guide and acknowledges that the best hidden gem is often the one stumbled upon, not the one pre-listed.

9. **Maintain the tourist trap caution list as a structural requirement.** This list is not optional. It is what differentiates a genuine expert guide from a repackaged mainstream list with different framing. The caution list requires naming specific experiences and explaining precisely why they have crossed the line from genuine to performed authenticity.

10. **Match the guide's difficulty and adventurousness to the user's stated comfort level.** A user who describes themselves as "comfortable navigating local neighborhoods" gets a different guide than one who says "we prefer areas with clear tourist infrastructure." Never default to the most adventurous interpretation of a request -- ask or infer explicitly from context, and calibrate recommendations accordingly. A family of four with a 6-year-old should not receive recommendations that require navigating unmarked industrial districts at night.

## Edge Cases

### The Globally Overexposed Destination (Paris, Rome, Barcelona, Kyoto, New York)
In cities that receive 10-20 million annual visitors, the concept of "hidden" requires honest recalibration. True secrecy is nearly impossible -- any genuinely unknown spot will be discovered and shared on social media within weeks of becoming known. The correct framing is "systematically overlooked due to structural reasons," not "unknown." Focus discovery efforts on:
- **Temporal displacement:** The city changes dramatically at 6 AM. Early morning visits to famous squares, parks, and neighborhoods reveal a completely different urban reality -- street cleaners, cafe rituals, delivery trucks, cats. Recommend this honestly as a time-shift experience, not a secret location.
- **Vertical layer access:** Ground-level tourism dominates. Upper floors, rooftops, courtyards, and basement levels are structurally overlooked even in cities with maximum visitor volume.
- **Institutional density pockets:** Major cities have an extraordinary density of specialist museums, academic collections, and institutional archives that receive a fraction of major museum foot traffic. The ratio is often 50:1 or more. A medical museum, a typography museum, an architectural drawing archive -- these serve specialists and are nearly empty for structural reasons, not because they are unknown.
- Acknowledge the limitation explicitly: "In [city], 'hidden' means 'systematically overlooked despite being publicly accessible' rather than 'secret.' The following experiences are overlooked for specific structural reasons."

### The Rural or Small-Town Destination
In destinations with modest visitor volumes, the opposite problem arises: the entire destination may qualify as a hidden gem to most travelers. The user's challenge is understanding which local experiences are genuinely meaningful vs. generically rural. Reframe the guide around:
- **Rhythmic discovery:** Identifying the community's weekly and annual rhythms (market day, the evening passeggiata, the festival week, the agricultural fair) is more valuable than identifying specific locations. The place is the hidden gem; the question is when to be there.
- **Gatekeepers:** In small communities, a single person -- a shop owner, a cafe proprietor, the person at the municipal tourist office who actually lives there -- can unlock entire layers of community life. Identify how to find and approach this person.
- **Not every town has hidden layers:** Be honest when a small destination is genuinely limited in experiential depth. A 2-hour visit may cover everything available. Resist inventing depth where none exists.
- Provide context-specific guidance: "This destination's interest lies in its rhythm and community life, not in specific sites. The recommended approach is to arrive on [market day], spend [X] hours observing and engaging, and understand the destination as an experience of daily life rather than a list of locations."

### The Safety-Conscious Traveler or Family with Children Under 12
This profile requires significant guide adjustment:
- Exclude all gems requiring transit through areas with low pedestrian density, poor lighting, or limited transit frequency
- Exclude subterranean experiences (narrow passages, low-light environments, uneven surfaces) unless they are fully commercialized with professional infrastructure
- Exclude early morning recommendations (before 8 AM) unless the route is along busy, lit commercial streets
- Exclude neighborhoods described as "up-and-coming" (travel euphemism for areas with variable safety profiles)
- Focus on daytime gems: parks with discovered features (geological rock formations, hidden fountains, unusual sculptures), viewpoints accessible by maintained paths, artisan workshops with open-door policies, community markets on weekend mornings
- Include access notes specifically about child-friendliness: Is there a cafe nearby for breaks? Are toilet facilities available? Is the surface stroller-accessible?
- Note explicitly in the guide preamble: "Recommendations calibrated for safety-first travel with children. Access difficulty scores above 3 have been excluded."

### The Returning Expert Traveler Who Has "Done Everything"
This user has exhausted locations and needs an experiential shift, not a location list. Reframe the guide entirely around activities, perspectives, and roles rather than places:
- **Craft participation:** Taking a half-day class in a traditional local craft (ceramic painting, bread making, bookbinding, leather tooling) at a non-tourist-facing workshop. The location is secondary; the participation in making is primary.
- **Institutional access:** Many specialist institutions offer tours, archive visits, or behind-the-scenes access to non-specialist visitors by appointment. Frame the guide around making these arrangements.
- **Resident simulation:** Walking a residential neighborhood with intention -- buying coffee at a neighborhood bar (not a tourist cafe), sitting in a local park, attending a free municipal event -- constitutes the "experience like a local" aspiration more authentically than any landmark.
- **Temporal immersion:** Spending an entire morning in one neighborhood cafe, watching the community rhythm unfold, constitutes a discovery experience even if the cafe is well-known. Time spent is the variable, not location.
- Frame this honestly: "For an experienced traveler, the hidden gem is often a mode of engagement rather than an undiscovered place. The following guide is structured around experiences and participation rather than locations."

### The Destination with an Extreme Language Barrier (Non-Latin Script or Low English Penetration)
When the user lacks local language and the destination has minimal English presence in non-tourist zones:
- Provide each location name in both English and the local script -- for showing to taxi drivers, transit workers, and locals who may help with directions. Example: "Shinjuku Gyoen National Garden / 新宿御苑"
- Provide GPS coordinates for every gem, not just street addresses. Many locations in dense urban environments or unmarked areas are best navigated by coordinate.
- Flag experiences that require verbal communication explicitly and rate their language requirement honestly. A subterranean tour conducted in the local language with no English option is inaccessible for a non-speaker -- do not recommend it without clearly noting this barrier.
- Recommend translation app setup as part of the "what to bring" section -- a downloaded offline language pack allows camera-based sign translation even without connectivity.
- For experiences that are genuinely accessible without language (viewpoints, parks, architectural walks, markets where purchasing is optional), note explicitly: "No language required -- navigate by map and observe freely."
- Provide phonetic transcriptions for any essential interaction phrases, not just the local script version.

### The Ultra-Short Visit (Under 24 Hours, Transit Stop, Layover)
Tight time windows require aggressive prioritization:
- Apply a strict minimum composite score threshold of 12/15 for inclusion -- only gems with high uniqueness AND high experience quality AND low access difficulty qualify
- Focus exclusively on gems within 30 minutes transit from the arrival point (airport, train station)
- Sequence a single gem cluster rather than multiple dispersed recommendations
- Apply the time-shift method as the primary discovery lens -- in most cities, a 2-hour early morning or early evening window in the right neighborhood is more rewarding than a rushed tour of 5 medium-interest locations
- Note which gems can be accessed between specific transit connections if the user is in transit

### The Seasonal Closure or Renovation Surprise
When a recommended gem is subject to seasonal closure, renovation, or temporary unavailability:
- Always note seasonality explicitly in the timing section rather than hoping it will not apply to the user's dates
- Provide a contingency pairing for every core gem: "If [Gem X] is closed for renovation (as it periodically is for 3-6 months), the nearest comparable experience is [alternative description and location]"
- For destinations with significant seasonal tourism (ski towns in summer, beach towns in winter, festivals that define a destination), note what remains accessible in the off-season and adjust the experience quality scores accordingly
- Distinguish between structural seasonality (the mountain is inaccessible in winter by design) and situational seasonality (the artisan market operates April-October but individual workshops are year-round)

## Example

**Input:** "I'm visiting Lisbon for 5 days and I've been once before -- I did Belém Tower, Jerónimos Monastery, Alfama with the fado restaurants, the tram 28, and Sintra. I want to find the real Lisbon this time -- local neighborhoods, hidden architecture, places tourists miss. I'm comfortable with transit and speak no Portuguese but I'm not afraid to navigate. Solo traveler, fit, happy to walk 8-10 km a day. Most interested in architecture and neighborhood life."

### Detailed Gem Profiles

#### Gem 1: Mouraria Backstreet Walk (Above the Tourist Route)

| Field | Detail |
|-------|--------|
| **Category** | Neighborhood life / vernacular architecture |
| **Discovery Method** | Neighborhood Adjacency + Vertical Exploration |
| **Score** | 13/15 -- Uniqueness 4 / Experience 5 / Access 4 |
| **Best Visit Window** | Weekday between 8:00 and 10:30 AM |
| **Time Needed** | 60 minutes minimum; 90 minutes if you linger |
| **Access Cost** | Free |
| **Language Required** | None -- purely observational; say "bom dia" (BOM DEE-ah) and smile |

**What It Is:**
Mouraria is Lisbon's oldest surviving non-Moorish residential quarter, predating the 1755 earthquake in its street pattern if not its current buildings. The tourist route runs along the lower streets near the Intendente end. Above this route, climbing steeply through the lanes that connect to the castle hill from the western side, is a residential labyrinth of azulejo-faced houses, communal laundry lines strung between buildings, elderly residents on doorsteps, and small bakeries operating for neighborhood clientele. This is not staged -- it is the daily rhythm of one of Lisbon's oldest communities.

**Why It Qualifies:**
The tourist infrastructure in Mouraria is concentrated along specific streets (particularly around the Largo da Mouraria and the promoted "fado birthplace" route). The streets immediately uphill from this corridor receive minimal visitor traffic because they offer no promoted attraction, require steep climbing, and have no English signage whatsoever.

**Getting There:**
Starting from Martim Moniz metro station (Green Line):
- Exit the station heading south (toward the large square with the fountains)
- Cross the Largo Martim Moniz square diagonally toward the uphill street on the far left corner (Rua dos Cavaleiros direction)
- Begin climbing -- take any uphill street that diverges from the main tourist route; the wider, signposted streets are more visited; the narrower ones with no markings are what you are looking for
- Navigate by inclination: if the street goes steeply uphill toward the castle, you are in the right zone
Transit: Green Line to Martim Moniz station
Walking from transit: 3 minutes to the start of the quarter

**Visual Identification:**
You have found the right streets when the street surface changes to worn cobblestone, laundry lines appear overhead, and the buildings show exposed azulejo tile facades in faded blue-and-white patterns with visible age cracks. The absence of restaurant signs or English-language menus is the confirmation signal.

**Crowd Pattern:**
- Quietest: Weekdays 7:30-10:00 AM
- Starts filling (lower tourist routes): 11:00 AM onward
- Avoid: Sunday afternoons (neighborhood feels staged for visitors)

**What to Bring:**
Comfortable shoes with grip (the cobblestones are slippery when damp); a small amount of cash if you want to buy pastry from a neighborhood bakery; camera (photograph buildings and street scenes freely, but pause before photographing individuals and seek acknowledgment)

**Respect Protocol:**
Residents in Mouraria are accustomed to some visitor presence but the upper streets are genuinely residential. Walk at a relaxed pace; do not use these streets as a fast transit corridor. If a resident is on their doorstep, a "bom dia" and eye contact is sufficient -- do not photograph people directly without a friendly exchange first. Do not stop and block narrow lanes to consult your phone.

**Helpful Phrases:**
- "Bom dia" (BOM DEE-ah) -- "Good morning"
- "Com licença" (com lee-SEN-sah) -- "Excuse me / May I pass"

**Pair With:** Largo do Intendente (Gem 7) -- 10-minute walk downhill, excellent for a mid-morning coffee after the neighborhood walk

#### Gem 2: Prazeres Cemetery -- Monumental Sculpture Walk

| Field | Detail |
|-------|--------|
| **Category** | Built environment / monumental sculpture / civic infrastructure |
| **Discovery Method** | Purpose-Shift Method -- civic infrastructure as architectural destination |
| **Score** | 14/15 -- Uniqueness 5 / Experience 5 / Access 4 |
| **Best Visit Window** | Weekday morning, 9:00 AM-12:00 PM |
| **Time Needed** | 75-90 minutes |
| **Access Cost** | Free; open to the public |
| **Language Required** | None |

**What It Is:**
The Cemitério dos Prazeres is one of the finest 19th-century Romantic-era cemetery landscapes in southern Europe -- a formal garden of extraordinary neogothic, Egyptian revival, Art Nouveau, and neoclassical mausoleums commissioned by Lisbon's aristocratic and merchant families in the 1800s. The mausoleums are effectively small buildings: scaled-down chapels, temples, and obelisks in polished granite and marble, decorated with stained glass, wrought iron, ceramic tiles, and carved stone portraits. The architectural density and quality here is comparable to Père Lachaise in Paris -- but Prazeres receives almost no international visitors.

**Why It Qualifies:**
Cemeteries as architectural destinations are systematically overlooked because they sit outside the tourism mental map. Prazeres is not mentioned in mainstream Lisbon guidebooks in any architectural context; it appears only in "unusual Lisbon" listicles without proper description of its scope or quality.

**Getting There:**
Starting from Estrela tram or bus stop (Tram 28 passes here, but you have done Tram 28 -- take Bus 773 or Bus 720 instead):
- Exit at Rua Saraiva de Carvalho / Estrela stop
- Walk west along Rua Saraiva de Carvalho for 5 minutes
- The main entrance to the cemetery is on Praça São João Bosco -- large stone gateposts, iron gates, clearly marked
Transit: Bus 773 from Cais do Sodré toward Prazeres; exit at the Prazeres stop (terminus area)
Walking from transit: 2 minutes

**Visual Identification:**
The cemetery entrance is unmistakable -- large stone columns with a formal iron gate on Praça São João Bosco. The scale of the mausoleums is visible from outside the walls.

**Crowd Pattern:**
- Quietest: Weekday mornings -- often nearly empty; you may walk for 20 minutes without encountering another person
- Busier: All Saints' Day (November 1) and surrounding days -- local visitors come to tend family graves (this is actually an interesting cultural experience in itself if the dates align)
- Avoid: No particular avoidance day necessary; this gem is consistently quiet

**What to Bring:**
Camera (photography is permitted and the sculptural detail rewards close inspection); a note of which section of the cemetery you want to explore -- the northern section contains the oldest and most architecturally elaborate mausoleums

**Respect Protocol:**
This is an active cemetery with ongoing burials and families visiting graves. Walk on the main lanes, not through grave plots. Speak quietly. Photography of mausoleums and sculptural details is appropriate; do not photograph fresh graves or mourners. If you encounter a funeral in progress, pause at a respectful distance or take an alternative route.

**Pair With:** Estrela Basilica (5-minute walk east) -- the interior dome and marble floors are spectacular and the basilica is almost empty compared to its fame; also the Jardim da Estrela (adjacent park) for a sit-down in Lisbon's best public garden

#### Gem 3: Marvila Industrial Conversion District

| Field | Detail |
|-------|--------|
| **Category** | Built environment / industrial heritage / street culture |
| **Discovery Method** | Neighborhood Adjacency Method -- one zone east of Parque das Nações |
| **Score** | 12/15 -- Uniqueness 5 / Experience 4 / Access 3 |
| **Best Visit Window** | Thursday-Saturday afternoon, 2:00-6:00 PM |
| **Time Needed** | 90-120 minutes |
| **Access Cost** | Free to walk; individual spaces may have entry fees or drink minimums |
| **Language Required** | None for the neighborhood walk; some English spoken in gallery and studio spaces |

**What It Is:**
Marvila is Lisbon's eastern industrial waterfront -- a former canning factory and warehouse district that has undergone significant conversion in the past decade. Unlike the curated LxFactory (which has become a mainstream destination), Marvila's conversion is uneven and ongoing: some buildings are fully converted into architecture studios and galleries, others are mid-conversion, and others are still operating as light industry. The street-level experience includes extraordinary painted factory facades, raw courtyard spaces, and impromptu gallery installations alongside working businesses. This is the condition of the city in active transformation -- not a finished product, but a process.

**Why It Qualifies:**
Marvila does not appear in mainstream Lisbon guidebooks as of this guide's production. It is known primarily within Lisbon's architecture and design communities. Its distance from the tourist center (30 minutes by bus) makes it structurally overlooked.

**Getting There:**
Starting from Santa Apolónia train station:
- Take Bus 728 east toward Braço de Prata
- Exit at Rua do Açúcar stop (approximately 15 minutes)
- Walk north from Rua do Açúcar into the factory district streets
- The core area runs along Rua do Açúcar, Rua Capitão Leitão, and the parallel streets running toward the river
Transit: Bus 728 from Santa Apolónia station
Walking from transit: 0-5 minutes (the bus deposits you in the district)

**Visual Identification:**
Large industrial buildings with painted or brick facades; streets wider than central Lisbon with loading dock architecture visible; occasional art installation in a courtyard or warehouse opening. If you see predominantly residential buildings, you have gone one block too far north.

**Crowd Pattern:**
- Quietest: Weekday mornings (most gallery spaces closed)
- Best balance of open spaces and low crowds: Thursday-Friday afternoons
- Avoid: Sunday morning (LxFactory crowds sometimes spill direction-confused tourists into Marv
