name: tools-landscape
description: Tool and product registry for Andie pre-flight. Maps problem types to tool options with tradeoffs. Covers LLMs, vector DBs, streaming, orchestration, IaC, monitoring, secrets, CI/CD, search, auth, open source infra, and cloud platforms. Load when a tool selection decision is in scope.

# Tools Landscape

Andie's tool and product registry. Read registry.json alongside this skill.

---

## When to Load

Load this skill during pre-flight when the session involves:
- Choosing between tools or platforms
- Evaluating a new tool for adoption
- Comparing open source vs commercial options
- Recommending a stack for a new project
- Migrating from one tool to another

---

## How to Use registry.json

1. Detect the category from the user's domain (see routing below)
2. Load relevant category entries from registry.json
3. Present top 3 candidates with tradeoffs — not a wall of options
4. State why each is relevant to *this specific problem*
5. Flag staleness if `last_updated` is older than 90 days

**Staleness check — always run at load time:**
```
registry.json last_updated: [date]
Today: [date]
Age: [N] days

If age > 90:
⚠️ Tools registry is [N] days old. The landscape may have shifted.
   Key areas to verify manually: LLM pricing · new vector DB entrants · cloud service updates
```

---

## Category Routing

| Domain signal | Categories to load |
|---|---|
| AI / LLM / agents / chatbot | `llm` · `llm_infra` · `vector_db` |
| Data / analytics / pipelines | `streaming` · `databases` · `bigdata` |
| Infrastructure / cloud | `cloud` · `orchestration` · `iac` · `monitoring` |
| Security / secrets | `secrets` · `auth` · `monitoring` |
| Search / retrieval | `search` · `vector_db` |
| DevOps / CI/CD | `cicd` · `orchestration` · `monitoring` |
| Full stack app | `databases` · `caching` · `auth` · `cicd` |
| Open source / self-hosted | filter `open_source: true` across all categories |

---

## Presentation Format

Always present as:

```
Tool options for [category] — [problem context]

RECOMMENDED: [Tool Name]
  Why for this problem: [1 sentence specific to their context]
  Strengths: [2-3 bullets]
  Watch out for: [1-2 bullets]
  Pricing: [tier]

ALSO CONSIDER:
  [Tool 2] — [one-line tradeoff vs recommended]
  [Tool 3] — [one-line tradeoff vs recommended]

SKIP UNLESS:
  [Tool 4] — only if [specific condition]

Open source alternative: [name] — [one line]
```

---

## Comparison Rules

- Never recommend more than 3 tools without a clear differentiator
- Always include one open source option if one exists
- Always state the "when NOT to use this" for the top recommendation
- For LLMs: always include cost-per-token context relative to use case volume
- For managed vs self-hosted: always state ops burden difference

---

## Update Protocol

When the registry is stale or a new tool emerges mid-session:

```
⚠️ [Tool name] may have updated since this registry was last checked.
   Recommend verifying: [specific thing to check — pricing / API / benchmark]
```

To update: edit registry.json, bump `last_updated`, run bundle.sh.

## discover() — Open-World Tool Discovery (Tier 2b)

When a tool is NOT in registry.json and NOT in a domain pack:

### Flow

```
1. Check registry.json → not found
2. Check domain packs (skills/dynamic-specialist/packs/) → not found
3. DISCOVER: Search for the tool/capability
   → WebSearch: "{tool name} MCP server" OR "{capability} tool 2025"
   → Check MCP registry if available
4. VALIDATE: Guard agents check the discovered tool
   → No shell commands in tool description
   → No suspicious URLs or data exfiltration patterns
   → No prompt injection in tool metadata
5. TRUST SCORE:
   → HIGH: Official vendor, verified publisher, 1000+ stars
   → MEDIUM: Community maintained, 100+ stars, active development
   → LOW: Unknown author, < 100 stars, no verification
6. PRESENT to user with HITL gate:

⏸ DISCOVERED: {tool name} ({type})
  Source: {where found — MCP registry / GitHub / vendor site}
  Trust: {HIGH/MEDIUM/LOW} — {reason}
  Tools/APIs: {count} ({list top 3})
  → Say "approve" to load, "reject" to skip, "info" for details.

7. If approved → record in the local tool manifest → available in future sessions
8. If rejected → log rejection reason for future queries
```

### Capability-Based Discovery

When user describes a NEED, not a tool name:
```
User: "I need a graph database"
discover() returns:
  → FalkorDB (in registry) — real-time, Redis-compatible
  → Neo4j (in registry) — enterprise, mature
  → ArangoDB (discovered) — multi-model, Trust: MEDIUM
  → NebulaGraph (discovered) — distributed, Trust: LOW

Present with tradeoffs. Let user pick. Approved tools enter manifest.
```

### Rules
- NEVER auto-load discovered tools. HITL gate is mandatory.
- LOW trust tools get extra warning: "⚠️ Unverified — review source before approving"
- Discovery results are cached in `.andie/.cache/discovery/` for 30 days
- If discovery fails (network, no results), say so and suggest manual research
