description

This skill should be used when the user asks to "document mode", "edit only docs", "just update the docs", "fast-path a doc change", or invokes "/brains:document". Canonical entry point for BRAINS document mode: an abbreviated spine for document-only changes that skips planning, teammate orchestration, nurture, and secure. Runs an eligibility gate, lightweight research, the full 2-4 question questionnaire, a slim ADR, inline document edits, direct star-chamber council review (replacing nurture+secure), and an inline commit. Supports --single, --parallel (default), and --debate modes for the review phase, plus --autopilot and --lean.

BRAINS Document Mode: Abbreviated Doc-Only Spine

Drive a document-only change through an eligibility gate, lightweight orientation, the full 2-4 question questionnaire, a slim ADR, inline edits, direct council review, and an inline commit. Document mode is the fast path for work that only edits documents (markdown and prose, not code): it skips /brains:map, teammate orchestration, /brains:nurture, and /brains:secure, reviewing the final document(s) directly with the star-chamber council instead. Default mode: --parallel with star-chamber review.

This skill is the canonical entry point for document mode. It is invocable directly (/brains:document "<topic>") and is also the delegation target of the /brains:brains Step-1 guard (the --document-mode flag and auto-detected doc-only path); both routes run this same spine with identical eligibility, gating, and behavior. Document mode never spawns teammate Claude Code instances (req 21).

Set the plugin base path:

BRAINS_PATH="<base directory from header>/../.."

Mode Behavior

Modes apply to the review phase (step 6). Eligibility, research, questionnaire, ADR, edits, and commit run identically across modes.

Mode	Document review
--single	Local self-review only — explicitly lower-assurance; warn that council review is unavailable.
--parallel (default)	Final document(s) reviewed by the star-chamber council via star-chamber review.
--debate	Multi-round council deliberation over the final document(s).

For --parallel and --debate, read and follow $BRAINS_PATH/references/multi-llm-protocol.md. Under --lean, read the compact excerpt at $BRAINS_PATH/references/multi-llm-protocol-compact.md instead; consult the full file only for debate-round synthesis or error handling.

Hard Gate

Do NOT proceed past the eligibility gate (step 1) when the change contains non-document code files under a manual --document-mode override — hard-refuse and direct the user to the full /brains:brains pipeline.

Process

1. Eligibility gate

Run the hybrid eligibility detection defined in $BRAINS_PATH/skills/document/references/eligibility-detection.md: deterministic bash classifies and counts the canonical changed set against the versioned document allow-list (.md, .markdown, .mdx, .rst, .txt, .adoc); the main LLM resolves in-scope target documents from the prompt for greenfield work.

A change is eligible only when it contains zero non-document files AND target documents ≤ 4. Target counts cover deliverables only — never BRAINS-generated artifacts (slim ADR, research, beads, diagrams).

Apply the mode-sensitive threshold behavior and asymmetric override exactly as the reference specifies: interactive warn-and-ask / autopilot detect-then-fallback with a loud notice for oversized-but-document-only scopes; hard-refuse when non-document code files are present (fenced/example code inside a document never triggers refusal). When detection routes to the full pipeline, stop this spine.

2. Lightweight research / orientation

Run a single lightweight research/orientation pass scoped to the target documents and the user's prompt. MAY skip when the scope is trivial. MUST NOT run the full multi-subagent research of /brains:brains.

If a useful orientation note is produced, write it to docs/research/YYYY-MM-DD-<slug>-research.md (committed to git). This note is a BRAINS-generated artifact and does not count toward the document ceiling.

3. Full interactive questionnaire (2-4 questions)

Run the full interactive 2-4 question questionnaire, with mode-dependent generation identical to /brains:brains steps 3 and 5. Do NOT reduce the question count below the standard 2-4 range — document edits routinely hide product or policy implications that the questionnaire surfaces.

Generation uses the same lightweight question-generation Agent subagent as /brains:brains — this is NOT a teammate Claude Code instance and does NOT constitute teammate orchestration (which req 21 forbids); it is the same in-session helper the core questionnaire already uses.

• --single: use a single question-generation subagent to produce the 2-4 question set with pros and cons; use its output directly.
• --parallel (default): run the question-generation subagent and concurrently invoke the star-chamber for its own candidate set, then merge and de-duplicate, per $BRAINS_PATH/references/multi-llm-protocol.md.
• --debate: run the subagent and star-chamber across rounds until convergence, per the debate protocol.

Present each question with pros and cons, accept the user's answer, and adapt the remaining set as new information arrives.

4. Slim ADR

Produce a slim ADR in docs/adr/ following $BRAINS_PATH/skills/document/references/slim-adr-template.md, using the standard filename and globally-sequential-NNN convention (YYYY-MM-DD-NNN-<title>.md). Retain Context, Decision, Requirements (RFC 2119), and Consequences; omit Assumed Versions and Diagram. The slim ADR is a BRAINS-generated artifact and does not count toward the document ceiling.

5. Inline document edits

Edit the target documents inline in the current session. MUST NOT invoke /brains:map, spawn teammate Claude Code instances, or invoke /brains:implement. SHOULD track work with lightweight beads tasks labeled brains:document:<slug>.

After editing, re-run only the cheap changed-set classification (reference §1–§2) against the now-changed working tree to confirm no non-document file was introduced and the target-document count is still ≤ 4 (excluding artifacts this spine authored). If editing accidentally introduced a code file or pushed the document count over the ceiling, react per the threshold/override rules before proceeding to review and commit.

6. Direct council review (replaces nurture + secure)

This step replaces the nurture and secure passes. MUST NOT invoke /brains:nurture or /brains:secure.

--parallel / --debate: review the final document(s) directly with the star-chamber council, in full. Write a context file holding the original prompt plus main-LLM-curated supporting materials (research and the slim ADR), then run, in ONE bash command:

SC_TMPDIR="<literal path>"; uvx star-chamber review --context-file "$SC_TMPDIR/context.txt" --format json <final doc paths>

Parse the JSON, present the council review to the user, and integrate accepted findings into the source documents. (Document mode's ≤ 4-document ceiling keeps the review payload well within context; there is no word-count gate.)

--single: perform a local self-review of the documents in place of the council review. Treat it as explicitly lower-assurance and warn the user that council review is unavailable and that --parallel is recommended.

7. Inline commit and .gitignore

Own the git responsibilities normally held by nurture under --scope phase-N by following the shared procedure at $BRAINS_PATH/references/commit-procedure.md: run git status --porcelain, commit the document changes atomically with a conventional-commit docs:-prefixed message, and update .gitignore for any generated artifacts. Do NOT push (the user or a chained gate pushes).

Output

• Slim ADR: docs/adr/YYYY-MM-DD-NNN-<slug>.md
• Optional orientation note: docs/research/YYYY-MM-DD-<slug>-research.md
• Edited target document(s), committed atomically with a docs:-prefixed message.

Phase Transition

After the document-mode spine completes:

"Document mode complete. Slim ADR written, document(s) edited and reviewed, changes committed.

Next steps:

• Push the commit when ready.
• /brains:brains — run the full pipeline if scope grew beyond document-only work."
