# Lot Traceability
Plan a lot trace from finished goods back to material, or the reverse, and record the breaks.
## When to use this skill
Use this skill when the user:
- traceability
- lot trace
- mock recall
- batch genealogy
## When not to use this skill
- The user wants a different domain's specialist skill.
- The task requires a licensed professional to decide, and the user only needs a referral note rather than a draft.
- The request asks you to deceive, evade a control, or hide material facts.
## Professional boundary
Quality and safety procedures are drafts for the site's quality system. Do not bypass a hold, calibration, or safety step.
## Operating boundaries
- Use only information the user provides or files they explicitly ask you to read. Do not invent metrics, laws, citations, prices, credentials, or clinical facts.
- Do not ask for passwords, API keys, tokens, seed phrases, one-time codes, or payment card data.
- Do not send data to an external service, install packages, or add network calls as part of this skill.
- Separate facts, assumptions, and recommendations. If a required input is missing, state the assumption or ask one focused question.
- If the user asks you to deceive a person, evade a control, forge a record, or cause harm, stop. Offer a legitimate alternative.
- Work product that affects money, employment, health, safety, or legal rights is a draft for a qualified human to review before it is used.
## Inputs to collect
- The lot to trace
- Systems involved
- Time target
- Known breaks
## Workflow
### 1. Define the question
where did this lot go, or what went into it.
### 2. Step 2
Use their systems. Do not invent genealogy.
### 3. Step 3
Record every break where the link is missing.
### 4. Step 4
Time the exercise. A trace that takes days is a finding if their target is hours.
### 5. Step 5
Name the owner of each break.
### 6. Step 6
Do not tell anyone to ship product they said is on hold.
## Output
Deliver a **trace exercise**.
- Purpose of this trace exercise, in two sentences.
- Facts the user supplied, listed separately from assumptions.
- The work itself, in the structure the workflow names.
- Open questions, risks, and the single next action with an owner.
- What a qualified reviewer still needs to confirm, if the domain is regulated.
## Quality bar
- Every number, date, name, and citation came from the user or is marked as an assumption.
- The artifact can be used without reading this skill again.
- Recommendations are specific enough that someone could accept or reject them.
- Boundaries were respected: no credentials requested, no unsupported professional claim, no deception.
## Example
### Scenario
Gus Moretti, plant manager at Redline Parts in Nisku, needs a trace exercise by 30 September 2026. A mock recall stops because a component lot was never recorded.
### Example data
```text
From: Gus Moretti, plant manager
Organization: Redline Parts, Nisku
Date: 14 September 2026
Needed by: 30 September 2026
A mock recall stops because a component lot was never recorded.
The lot to trace: Line 2, recorded 14 September 2026. No supporting file attached
Systems involved: the one named in the ask. Version and owner not recorded
Time target: 180
Known breaks: Lot 26-0914. Stated in the ask, not documented anywhere else
```
### Example outcome
**Trace exercise**
To: Gus Moretti, plant manager, Redline Parts
Date: 14 September 2026 · Needed by: 30 September 2026
**Decision**
Records the break, times the exercise, and assigns the recording gap.
**What the file supports**
| Input | Value | Status |
| --- | --- | --- |
| The lot to trace | Line 2, recorded 14 September 2026. No supporting file attached | Needs confirmation |
| Systems involved | the one named in the ask. Version and owner not recorded | Carried into the draft |
| Time target | 180 | Carried into the draft |
| Known breaks | Lot 26-0914. Stated in the ask, not documented anywhere else | Needs confirmation |
**How this draft was built**
**1. Define the question**
where did this lot go, or what went into it.
**2. Use their systems. Do not invent genealogy**
**3. Record every break where the link is missing**
**4. Time the exercise. A trace that takes days is a finding if their target is hours**
**5. Name the owner of each break**
**Deliberately not done**
- Invented genealogy.
- A trace that hides a break.
- Shipping a held lot.
**Open items for a human**
- Confirm every row marked *Needs confirmation* above before this leaves draft.
- Anything absent from the file stayed absent. No figure, date, or name was supplied from outside it.
Next: Gus Moretti by 30 September 2026. This is a draft, not a sign-off.
## Anti-patterns
- Invented genealogy
- A trace that hides a break
- Shipping a held lot
