Grill With Docs

# Grill with Docs > Derived from [Matt Pocock's grill-with-docs](https://github.com/mattpocock/skills/tree/main/skills/engineering/grill-with-docs) (MIT, © 2026 Matt Pocock). Matt's interview discipline + docs-anchored grilling rules preserved verbatim under MIT. Additions in this repo: 3 stdlib validators (CONTEXT.md linter, ADR scanner, glossary↔code consistency check), 3 in-depth references each citing 7+ authoritative sources, `cs-grill-with-docs` agent, `/cs:grill-with-docs` command. See [Wrapper additions](#wrapper-additions) below. <what-to-do> Interview me relentlessly about every aspect of this plan until we reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer. Ask the questions one at a time, waiting for feedback on each question before continuing. If a question can be answered by exploring the codebase, explore the codebase instead. </what-to-do> <supporting-info> ## Domain awareness During codebase exploration, also look for existing documentation: ### File structure Most repos have a single context: ``` / ├── CONTEXT.md ├── docs/ │ └── adr/ │ ├── 0001-event-sourced-orders.md │ └── 0002-postgres-for-write-model.md └── src/ ``` If a `CONTEXT-MAP.md` exists at the root, the repo has multiple contexts. The map points to where each one lives: ``` / ├── CONTEXT-MAP.md ├── docs/ │ └── adr/ ← system-wide decisions ├── src/ │ ├── ordering/ │ │ ├── CONTEXT.md │ │ └── docs/adr/ ← context-specific decisions │ └── billing/ │ ├── CONTEXT.md │ └── docs/adr/ ``` Create files lazily — only when you have something to write. If no `CONTEXT.md` exists, create one when the first term is resolved. If no `docs/adr/` exists, create it when the first ADR is needed. ## During the session ### Challenge against the glossary When the user uses a term that conflicts with the existing language in `CONTEXT.md`, call it out immediately. "Your glossary defines 'cancellation' as X, but you seem to mean Y — which is it?" ### Sharpen fuzzy language When the user uses vague or overloaded terms, propose a precise canonical term. "You're saying 'account' — do you mean the Customer or the User? Those are different things." ### Discuss concrete scenarios When domain relationships are being discussed, stress-test them with specific scenarios. Invent scenarios that probe edge cases and force the user to be precise about the boundaries between concepts. ### Cross-reference with code When the user states how something works, check whether the code agrees. If you find a contradiction, surface it: "Your code cancels entire Orders, but you just said partial cancellation is possible — which is right?" ### Update CONTEXT.md inline When a term is resolved, update `CONTEXT.md` right there. Don't batch these up — capture them as they happen. Use the format in [CONTEXT-FORMAT.md](./CONTEXT-FORMAT.md). `CONTEXT.md` should be totally devoid of implementation details. Do not treat `CONTEXT.md` as a spec, a scratch pad, or a repository for implementation decisions. It is a glossary and nothing else. ### Offer ADRs sparingly Only offer to create an ADR when all three are true: 1. **Hard to reverse** — the cost of changing your mind later is meaningful 2. **Surprising without context** — a future reader will wonder "why did they do it this way?" 3. **The result of a real trade-off** — there were genuine alternatives and you picked one for specific reasons If any of the three is missing, skip the ADR. Use the format in [ADR-FORMAT.md](./ADR-FORMAT.md). </supporting-info> ## Wrapper Additions The additions below are **not** part of Matt's upstream skill. They operationalize the upstream's rules into deterministic, stdlib-only validators that pair naturally with the interview loop. ### Workflow (with wrapper tools) 1. **Pre-flight (before the first question):** - Run `scripts/context_md_linter.py CONTEXT.md` if a `CONTEXT.md` exists — confirms the glossary is well-formed before grilling against it. - Run `scripts/adr_scanner.py docs/adr/` if `docs/adr/` exists — surfaces numbering gaps, malformed ADRs, status-frontmatter inconsistencies. - Run `scripts/glossary_code_consistency.py --context CONTEXT.md --code src/` — flags defined-but-unused terms (dead glossary) and code-only common nouns that may need definitions. Use these flags as opening grill questions. 2. **During the session (Matt's rules apply):** - One question per turn, walking depth-first. - When a term is sharpened: edit `CONTEXT.md` immediately; re-run `context_md_linter.py` if the edit is structural. - When an ADR is warranted: write it under `docs/adr/`; re-run `adr_scanner.py` to confirm numbering. 3. **Closing:** - Final `glossary_code_consistency.py` run to confirm no new orphan terms were introduced. - Summarize: terms added/refined, ADRs written, scenarios discussed, open items. ### Tools (stdlib-only) | Tool | One-line role | |---|---| | `scripts/context_md_linter.py` | Validate `CONTEXT.md` against the CONTEXT-FORMAT.md structure. PASS/WARN/FAIL per rule. | | `scripts/adr_scanner.py` | Walk `docs/adr/`, check `NNNN-slug.md` pattern, numbering integrity, body completeness. | | `scripts/glossary_code_consistency.py` | Cross-reference bold terms in `CONTEXT.md` against codebase usage. Flag dead glossary + code-only common nouns. | ### References (citations behind each rule) - [`references/ubiquitous_language.md`](references/ubiquitous_language.md) — why a glossary belongs in source control (Evans, Vernon, Khononov, Wlaschin, Brandolini, Avram & Marinescu, Fowler) - [`references/adr_practice.md`](references/adr_practice.md) — when an ADR earns its keep (Nygard, Tyree & Akerman, Zimmermann Y-statements, MADR, ThoughtWorks Radar, adr-tools, Backstage) - [`references/context_md_as_artifact.md`](references/context_md_as_artifact.md) — CONTEXT.md as living artifact (Khononov on language drift, Kernighan on naming, BoundedContext bliki, Confluent on data contracts, Brandolini on EventStorming glossary) ### Companion - Agent: `cs-grill-with-docs` (see `../../agents/cs-grill-with-docs.md`) - Command: `/cs:grill-with-docs` (see `../../commands/cs-grill-with-docs.md`) --- **Version:** 1.0.0 **Derived:** Matt Pocock's grill-with-docs (MIT) + this repo's wrapper
