description	Use when the user says "grill me", asks to stress-test a plan, wants to be interviewed or asked the questions needed before building, offers a vague feature idea, or wants grounded planning before non-trivial implementation

Grill

Grill turns unclear intent into an implementation-ready plan. It researches first — grounding itself in the code, docs, and brain and writing a research doc before engaging the user — then interviews only on what that research could not resolve. The core principle is: ask only questions the repo, docs, glossary, ADRs, or fetched primary sources cannot answer. A well-grounded grill may ask very few questions, or none; that is the goal, not a shortcut. Research is scoped to a fixed surface taxonomy and recorded in a coverage ledger; the ledger's open rows are the question list, so completeness is an enumerable check rather than a matter of when the interviewer runs out of ideas. See RESEARCH-GATE.md.

When to Use

Use this skill when:

• The user says grill me, stress-test this plan, or asks for a planning interview.
• The user proposes a non-trivial implementation and shared understanding is not yet strong enough to code.
• A feature idea, migration, architecture change, domain model, or integration has unresolved product intent, trade-offs, boundaries, contracts, or source of truth.

Do not use this skill for tiny mechanical edits, direct bug fixes with an obvious cause, or execution of an already-written plan (brain/plans/).

Process

1. Ground yourself before asking the first question. If the user already supplied a ticket, issue, spec, or written idea, read it fully first — it is the seed for what to research, not a substitute for researching. Then read the relevant code, tests, configs, routes, schemas, package manifests, README instructions, and any nearby plans or specs. If brain/codebase/ already maps the area you are touching, read that map first and scope your own reading to the gaps it leaves — do not re-discover what it already documents. Each map records the commit it was mapped at; if git rev-parse --short HEAD has moved past that and touched the mapped paths, treat the map as history and verify against the current files.
2. Read the domain context and project memory from the brain vault. The SessionStart hook injects brain/index.md; from it read brain/context.md (the domain glossary), the relevant notes in brain/decisions/ (ADRs), and brain/principles.md plus each principle file it links. Ground your questions and the plan in those, and do not ask the user to restate anything the brain already records. A fresh project may have an empty or missing vault — that is fine; do not invent content. When a brain note conflicts with what the current code shows, flag the conflict and cite the note's date; never let stale memory override present evidence.
3. Decide whether external research adds value, and what kind — run the three-stage cascade every time (full detail in RESEARCH-GATE.md). (a) An explicit request wins: if the ticket or user asks for prior art, alternatives, best practices, official docs, or names an external technology, external research is required; only an explicit opt-out overrides it. (b) Otherwise weigh implicit signals — lean in on high-risk topics (security, payments, privacy, migrations, compliance, external APIs), when there are fewer than three direct local examples, or on an adjacent-domain match (a near neighbour exists but not the exact case); lean out when a strong, recently-touched local pattern already covers it. An ADR-worthy decision forces the deeper path. (c) Classify the intent so step 4 routes it: implementation-guidance (approach settled → doc-verify), landscape (what options exist → delegate to afk:research), or mixed (landscape first to shortlist, then doc-verify the choice — sequential). Doc-verification is a hard prerequisite for any library, API, SDK, CLI, or cloud service the plan will touch: never trust training data for signatures, config keys, or versions — fetch Context7 or current official docs, record the URL and version, and run the deprecation/sunset check before any external API enters a contract. Announce the decision in one line.
4. Whenever step 3 found research adds value, dispatch bounded read-only subagents in parallel; scale depth to the step-3 signals (a throwaway gets the codebase scout only; a payments or migration decision gets the full set plus landscape delegation). Scouts report findings only — never recommendations; prescription is the plan's job.
   • Codebase scout: inspect entrypoints, neighboring files, tests, schemas, configs, and existing patterns. Report file paths, current behavior, contradictions, untested surfaces, open questions, and the three-examples / adjacent-domain verdict from step 3.
   • External research: for landscape or mixed intent, the grill lead calls the afk:research skill (it forks its own context — never nest it inside a scout). For implementation-guidance, doc-verify the specific library, API, SDK, or CLI per step 3. Report source URLs, versions, exact API shapes, deprecation status, and risks.
   • Domain scout, when useful: read brain/context.md and brain/decisions/. Report glossary conflicts, prior decisions, and terms needing precision.
5. Synthesize the research yourself and write the research doc as your first artifact, before you engage the user with a Background or any question. Verify important claims against files or fetched sources first — a subagent report is not truth, and an absence claim ("there is no X") must be checked against the repo before it is recorded. The trigger is positive, not discretionary: if any scout ran or any external fact was fetched, you write brain/plans/<slug>.research.md using RESEARCH-FORMAT.md — what the codebase and sources ARE today, citation-heavy, no recommendations, opening with a one-line research-value rating (high/moderate/low) and closing with the Coverage ledger (the fixed surface taxonomy in RESEARCH-GATE.md, each surface marked resolved-by-evidence, open-needs-user, or n/a-derived). It is the companion to the plan and the reusable input every later phase (afk:implement, afk:qa) reads instead of re-discovering. Skip the doc only when no scout ran and no external fact was fetched (a genuinely trivial plan).
6. Open with a Background written like a product owner, after the research doc exists and before any question. In a few sentences, restate what the user is asking for as a product owner framing the work: the problem, who it is for, the outcome they want, and the scope as you currently understand it from the request, the ticket, and your research. Ground it in what you found — do not invent requirements. Then preview the ledger: list the surfaces research already resolved (so the user sees what you will not ask about) and how many open rows remain ("3 decisions need you; here's the first"), and state your read of the intent, inviting correction. This gives the user something concrete to react to instead of a cold first question.
7. Now interview the ledger's open-needs-user rows, in priority order (blast-radius and irreversibility first, then the experience bar, then edge cases, then cosmetics). Ask one at a time, waiting for each answer, each as (the question, why it matters / what breaks, and your recommended default-if-silent). Silence or "your call" resolves a non-blocking row to its stated default — except the Stop-and-Ask surfaces below, which must be asked as real questions even when a default exists. If research already closed every row, say so and go straight to the plan — do not manufacture questions.
8. Challenge glossary conflicts immediately. If the user uses a term differently from brain/context.md, say what the glossary says and ask which meaning is authoritative.
9. Sharpen fuzzy or overloaded language. Propose canonical terms when concepts such as account, user, customer, order, or cancellation may mean different things.
10. Stress-test decisions with concrete scenarios, edge cases, failure modes, permission boundaries, lifecycle states, and cross-system contracts. For experience-bearing work — UI, dashboards, reports, anything whose value is what the user understands or can do — also grill the quality bar, not just the data: which insight or outcome the user must get, what must be visible at a glance, and how "good" will be judged (legibility, scannability). Treat that bar as a contract, not taste — without it, implementation ships something that runs but does not deliver, and QA has no bar to fail it against.
11. Cross-reference user claims against code and fetched sources. Surface contradictions explicitly and ask which source should win. When an answer surfaces a new what-is fact, append it to the research doc before the plan cites it — research is ground truth, not a write-once snapshot.
12. Update brain/context.md immediately when a glossary term is resolved. Use it only as a glossary: no implementation details, specs, scratch notes, or plan content. If creating it, use CONTEXT-FORMAT.md.
13. Offer an ADR only when the decision is hard to reverse, surprising without context, and the result of a real trade-off. If creating one, use ADR-FORMAT.md.
14. Continue until the coverage ledger closes: every surface is resolved-by-evidence, resolved-by-user, default-accepted, or n/a-derived (with a one-line reason) — none left open. This is an enumerable check, not a feel; contracts clear, ambiguous terms defined, key edge cases answered, and source-of-truth conflicts settled all fall out of it.
15. If during the interview the user pointed you at a reference repo they cloned locally ("do it like that repo", "see the pattern in Y"), read it and record it in the plan: its origin (GitHub URL or name) and its local path, so implementation reads the real source instead of a remembered pattern.
16. Write the agreed plan to brain/plans/<slug>.md and add a wikilink to it in brain/plans/index.md, creating the vault if it does not exist yet. (Do not edit brain/index.md — the auto-index hook maintains it.) If you wrote a research doc in step 5, link it from the plan's ## Research line so the plan stays the single entrypoint. Every decision or contract that rests on a finding must cite it ([[<slug>.research#<finding>]]) so the plan's prescription is traceable back to the descriptive evidence; a choice made in the interview with no finding behind it carries an explicit (no research — chosen in interview) tag instead. Keep the finding in research, the choice in the plan, never duplicate the prose. Include decisions made, contracts between parts, relevant glossary or ADR updates, an explicit ## Acceptance bar for experience-bearing work (the user-visible quality criteria, so afk:implement has a target and afk:qa has a bar), and the implementation task list grouped into parallel waves (see Output). Decide the schedule here so afk:implement does not have to re-derive it: mark which slices are independent (disjoint files, no shared contract) so they run concurrently, and which depend on earlier slices; give every slice the files it owns and what it depends on. Every contract that depends on a library, SDK, or API must cite the source URL and version it was doc-verified against (per step 3).

Stop and Ask

STOP and ask the user when:

• Product intent, priority, or acceptable trade-off cannot be inferred from the repo, glossary, ADRs, or docs.
• Multiple sources of truth conflict and choosing one would change behavior.
• A required external source, credential, account, environment, or proprietary document is unavailable.
• Continuing would require making a business, legal, security, data retention, privacy, or rollout decision without an owner.

Do not ask the user about facts that can be discovered by reading the repo or fetched primary sources.

Red Flags

Thought	Reality
"I can ask the user how the code works."	Read the code first and ask only when the code conflicts with intent or another source.
"Let me start interviewing to understand the task."	Research first and write the research doc; the interview opens only after, and only on what research and the ticket left unresolved.
"There's a ticket, so I can skip research and just clarify it."	A ticket is the seed for research, not a replacement. Research it, then ask only what stays unclear.
"The plan is mostly obvious."	Non-trivial work needs explicit contracts, edge cases, and source-of-truth decisions before implementation.
"The data contracts are nailed, so the plan is ready."	For experience-bearing work, contracts aren't the bar. Name the user-visible quality bar (the insight, what's legible at a glance) as ## Acceptance, or implement ships something that runs but doesn't deliver.
"I'll batch glossary updates at the end."	Update brain/context.md when the term is resolved so later questions use the canonical meaning.
"This decision feels important, so it needs an ADR."	ADRs are only for decisions that are hard to reverse, surprising without context, and trade-off driven.
"A subagent report is enough."	The lead must synthesize and verify important claims before asking or planning.
"I know this library/API well enough to write the contract."	Training data drifts. Fetch the current docs and verify every API name, parameter, and version before it goes in the plan (per step 3).
"The interview feels done."	It's done when every coverage-ledger surface is non-open with a recorded status, not when you run out of questions.
"This work is small, so skip the research doc."	Write whenever any scout ran or any external fact was fetched. Skip only when neither happened.

Output

Create the plan file (brain/plans/<slug>.md) with this shape:

# <Plan Title>

## Research
- [[<slug>.research]] — descriptive findings the scouts produced (omit if none written)

## Context
- <What is being changed and why>
- <Relevant code, glossary, ADR, or external source constraints>
- <Reference repos the user cloned to copy a pattern: origin (GitHub URL) and local path>

## Decisions
- <Resolved decision and rationale> — grounds: [[<slug>.research#<finding>]] (or `(no research — chosen in interview)`)


  — grounds: [[.research#]] (or )



 


 



Group implementation into waves so the orchestrator can delegate the schedule
without re-deriving it. Slices in one wave touch disjoint files and share no
contract, so they run in parallel; each later wave depends on earlier ones. For
every slice, give the files it  and what it .

Each slice is one vertical behavior — its test and its implementation together,
never a tests-only slice and a separate implementation-only slice (that is
horizontal slicing). Make Wave 1 the thinnest end-to-end happy path as a tracer
bullet that proves the whole path works; later waves add validation and edge
cases behind it.

End the session by telling the user the plan is ready, naming the exact plan path (brain/plans/<slug>.md) and the research doc if you wrote one (brain/plans/<slug>.research.md), and stating that it is the input to afk:implement (or afk:batch when the plan splits into many independently-mergeable units the user wants implemented as parallel PRs).
