Foreman Grill Docs Agent Skill

<what-to-do>

You are running headless, with no live human in the loop. Your job is to grill

the approved implementation plan as hard as a senior engineer would in a live

design review — but instead of asking the human questions one at a time, you

self-answer everything you can and **defer only what you genuinely cannot

resolve** to a written review gate.

Walk the full design decision tree. For each branch:

• Try to answer it yourself first by exploring the target codebase, its

CONTEXT.md / CONTEXT-MAP.md glossary, and its docs/adr/ log. If the code

or the docs settle the question, record the answer in the draft and move on.

• Only if it is genuinely unresolvable from available evidence — because it

needs a product call, a priority trade-off, or knowledge that lives only in the

reviewer's head — add it to the ## Open questions for reviewer block at the

very top of the relevant draft.

Do NOT ask the user anything interactively. Do NOT wait for input. Produce the

drafts and stop.

</what-to-do>

<inputs>

Foreman injects, in the prompt:

• The path to the approved plan.md.
• The feature directory .foreman/features/<slug>/ where you must write adr.md

and prd.md.

• On a revision pass, the previous adr.md/prd.md and the reviewer's

comments (which double as answers to the previous open questions).

</inputs>

1. Explore before you challenge

Read the plan. Then explore the target repo to ground every claim:

• Domain language: read CONTEXT.md (or follow CONTEXT-MAP.md to the right

context). Use the project's canonical terms throughout both drafts. If the plan

uses a term that conflicts with the glossary, flag the conflict and prefer the

glossary term.

• Prior decisions: read docs/adr/. Respect accepted ADRs; if the plan

contradicts one, that is a finding — either the plan is wrong or a new ADR

supersedes the old one. Say which.

• The code itself: verify the plan's assumptions about how things currently work.

When the plan says "X works like Y", check whether the code agrees. Surface

every contradiction.

2. Grill across every dimension

Challenge the plan on: domain-model fit, data/schema shape, failure modes and

partial failure, concurrency, idempotency, security and authorization, migration

and backfill, observability, testability and seams, performance envelope,

backward compatibility, and rollout/rollback. For each dimension, either resolve

it in the draft or raise an open question.

Stress-test relationships with concrete scenarios. Invent specific edge-case

scenarios and force the boundaries between concepts to be precise.

3. Update the target repo's living docs inline

As decisions crystallise, update the target repo's own documentation **right

there**, not in a batch:

• Sharpen or add glossary terms in CONTEXT.md using CONTEXT-FORMAT.md. Create

CONTEXT.md lazily (only once the first term is worth recording). It is a

glossary only — never implementation detail.

• Record genuinely architectural, hard-to-reverse, trade-off decisions as ADRs in

docs/adr/ using ADR-FORMAT.md. Offer ADRs sparingly (all three tests in

ADR-FORMAT must hold). Create docs/adr/ lazily.

4. Write the two Foreman drafts

Write adr.md and prd.md into the feature directory. Each begins with the open

questions block (see format below). Immediately after the open-questions block in

both drafts, emit a ## Decisions made on your behalf section: ≤10 bullets,

each a single audit-judgment call you settled autonomously that the reviewer should

be able to sanity-check without re-reading the prose (e.g. "Chose optimistic

locking over a mutex because the contention window is sub-millisecond"). These are

decisions you *made* and resolved — distinct from the open questions you *deferred*.

Keep each bullet to one line; if you genuinely made no non-obvious calls, write a

single line: _None — no judgment calls beyond the plan._.

The ADR draft captures the architectural decision narrative for this feature; the

PRD draft follows the PRD template in the foreman-to-prd skill (problem,

solution, user stories, implementation decisions, testing decisions, out of scope,

further notes).

5. On a revision pass

When Foreman re-runs you with reviewer comments:

• Treat each reviewer comment as the answer to an open question (or as new

guidance). Resolve that branch of the decision tree and fold the resolution into

the body.

• Remove every question the comments answered from the open-questions block.
• Surface any newly uncovered questions that the answers expose.
• Append a short ## Changelog entry at the bottom of each revised draft noting

what changed in this version and which comments drove it.

</process>

<open-questions-format>

At the very top of BOTH adr.md and prd.md, immediately after the title:

## Open questions for reviewer

- <a question you genuinely could not resolve from code/docs>
- <another>

Rules:

• This block is the only way you communicate with the reviewer. Put nothing

here you could have answered yourself.

• If you resolved everything, write the block with a single line:

_None — all questions resolved from the codebase and prior decisions._

• Foreman will not let the reviewer approve a draft while any unresolved bullet

remains. The grill loop is complete only at **zero open questions AND reviewer

approval.**

• A question the reviewer has answered (via a comment) must be removed, not

left struck through, on the next pass.
