Domain Brainstorm

Kill criteria (read before running)

After ≥8 invocations, read .claude-code-hermit/state/proposal-metrics.jsonl and filter events where type:"brainstorm-emit" and skill:"domain-brainstorm". Count CREATE vs total emits with ideas (triage-survival) and read status: of the resulting PROP files (PROP-acceptance). If triage-survival < 25% or PROP-acceptance < 30%, cut this skill rather than tune it — signal-to-noise isn't there.

Gate 0 — Gather inputs

Read these in parallel — all are cheap working-tree reads. Do not run the test suite or install tools.

Git activity

git log --oneline -50
git log --format= --name-only -50 | sort | uniq -c | sort -rn | head -20

Note the 5 most-churned files and any subsystem clusters.

Test signal Read .claude-code-hermit/state/last-test.json (written by /dev-test). Extract status, exit_code, and duration_ms. If absent or last-modified >24h ago, note "no recent test run" — do not run the suite.

Manifest drift ls for package.json, Cargo.toml, pyproject.toml, go.mod. For each found, check its lockfile (package-lock.json/yarn.lock/pnpm-lock.yaml, Cargo.lock, poetry.lock, go.sum) exists alongside it. Flag any mismatch.

README coverage Read README.md and a one-level ls of the repo root. Note features or modules claimed in the README with no corresponding directory or file visible.

Gate 1 — Generate ideas (max 2)

Think across all four inputs. For each candidate, both constraints must pass before including it:

1. Concrete friction — state the operator pain in one sentence. What breaks, slows, or misleads today without this fix? If no specific pain, discard.
2. ≥2 named grounding items — cite at least two by name (e.g. git:cli/index.js, state:last-test.json duration=38s, file:package-lock.json missing, readme:§Feature X). These support the friction; friction is the bar.

Map each passing idea to the closest dev prefix: [missing-tests], [tech-debt], [dependency], [tooling], or [architecture].

Cap at 2 ideas. Emit-zero if none pass. Record discarded candidates (one line each) for Gate 4.

Gate 2 — Create proposals

For each idea, invoke /claude-code-hermit:proposal-create once:

Title: [<prefix>] <short idea title>
Evidence Source: capability-brainstorm
Evidence: <one paragraph: friction sentence + named grounding items>

Set frontmatter: source: auto-detected, category: improvement.

Evidence Source: capability-brainstorm is reused intentionally: it is the only source proposal-triage recognizes for the single-pass recurrence bypass, and adding a dedicated domain-brainstorm source is a core edit this skill deliberately avoids. The cost: domain-brainstorm proposals carry capability-brainstorm provenance to any consumer that buckets by evidence source. Per-skill kill metrics are unaffected (they read the brainstorm-emit events below, which are tagged skill:"domain-brainstorm"). If this skill graduates from pilot, promote it to a first-class triage bypass source.

Parse the verdict:

• CREATE — note PROP-NNN.
• SUPPRESS — <code> — record suppression code; don't retry.
• DUPLICATE:<PROP-ID> — record existing ID; don't create.

After each verdict, append a metrics event via the shared helper:

bun "${CLAUDE_PLUGIN_ROOT}/scripts/append-metrics.ts" .claude-code-hermit/state/proposal-metrics.jsonl '{"ts":"<now ISO>","type":"brainstorm-emit","skill":"domain-brainstorm","verdict":"<CREATE|SUPPRESS|DUPLICATE>","proposal_id":null}'

Set "proposal_id":"PROP-NNN" for CREATE events; use JSON null for SUPPRESS/DUPLICATE events.

This event is what the kill-criteria audit reads — proposal-create's own created event does not carry per-skill provenance.

Do NOT invoke proposal-triage directly — /proposal-create handles it.

Gate 3 — Emit batch message

Send one message per the Operator Notification protocol in CLAUDE.md.

Zero-emit:

🔧 Domain brainstorm — 0 ideas emitted (<reason: thin context | all suppressed | all duplicates>)

Non-zero:

🔧 Domain brainstorm (<N> idea(s))

1. **[prefix] <title>** — <one-line description>
   _Grounding: <item 1>, <item 2>_
   _Friction: <one-sentence pain>_
   PROP-NNN created  ·  (or: suppressed — <code>  ·  or: duplicate of PROP-NNN)

Gate 4 — Compiled artifact (non-empty runs only)

If ≥1 PROP was created (not suppressed or duplicate), write:

.claude-code-hermit/compiled/domain-brainstorm-YYYY-MM-DD-HHMM.md

---
title: Domain brainstorm — <ISO timestamp>
type: domain-brainstorm
created: <ISO timestamp with timezone>
tags: [domain-brainstorm, ideation]
source: interactive
proposals_created: [PROP-NNN, ...]
---

Body (150-line cap): ideas that passed (one paragraph each), discarded candidates (one line each), triage verdicts, inputs scanned (paths only, no content).

Do not tag foundational — this is a time-bounded ideation snapshot.

Zero-emit runs: skip the artifact entirely. Log one line to SHELL.md Findings: domain-brainstorm: 0 ideas emitted (<reason>)
