description	Mine recent Claude Code sessions for non-obvious, multi-file CLAUDE.md candidates, adversarially verify them, and propose paste-ready additions. Use when the user wants to harvest documentation-worthy patterns/gotchas from past coding sessions into a project's CLAUDE.md, or says "mine my sessions for CLAUDE.md", "what should be in my CLAUDE.md", "/mine-claude-md".

mine-claude-md

Harvest non-obvious knowledge out of a project's recent Claude Code sessions and turn it into proposed CLAUDE.md additions — without inventing anything. This runs a bundled dynamic workflow that mines candidates in parallel, has independent skeptics adversarially challenge each one (reject-by-default), loops until the well runs dry, and synthesizes the survivors into a paste-ready report. It only proposes — it never edits your CLAUDE.md.

Requirements (check first)

This skill drives Claude Code's dynamic workflows feature. Before running, confirm:

• Claude Code v2.1.154+ and a paid plan (Pro/Max/Team/Enterprise) or API access.
• Workflows are enabled (/config → Dynamic workflows, or disableWorkflows not set, and CLAUDE_CODE_DISABLE_WORKFLOWS unset).

If workflows are disabled, the Workflow tool call below will fail. If it does, tell the user to enable Dynamic workflows in /config and re-run — do not fall back to doing the mining inline (the whole point is the parallel adversarial-verification harness).

Resolve the bundled workflow path

The orchestration script ships inside this plugin. Resolve its absolute path now — this works whether the plugin is installed at the personal, project, or plugin level, and regardless of the current working directory:

echo "${CLAUDE_SKILL_DIR}/../../workflows/mine-claude-md-from-sessions.workflow.js"

Use the path printed above as the scriptPath argument. Do not retype or guess it.

Gather inputs

Determine the workflow args before launching:

• projectPath (required): the absolute path to the repo to mine. Default to the current project root (${CLAUDE_PROJECT_DIR} or the cwd) unless the user named a different repo.
• sessionCount (optional, default 20): how many recent sessions to read.
• maxRounds (optional, default 6): safety cap on mining rounds.
• dryRounds (optional, default 2): consecutive empty rounds that mean "done".
• miners (optional): miners per round; auto-scales 2–4 from session count if omitted.

If projectPath is ambiguous, ask the user once. Otherwise proceed with the current project.

Run it

Call the Workflow tool with:

• scriptPath: the absolute path resolved above.
• args: an object, e.g. { "projectPath": "/abs/path/to/repo", "sessionCount": 20 }.

The run executes in the background across these phases:

1. Discover — resolve the session store, build one merged, deduped digest of recent sessions (CLAUDE.md included once so nothing re-reads it).
2. Mine — parallel miners propose non-obvious, multi-file, non-structural candidates.
3. Verify — one combined-lens skeptic per candidate adversarially tries to break it; survives only if it withstands both the structure lens and the novelty/truth lens.
4. Synthesize — assemble survivors into a report with a paste-ready "Suggested CLAUDE.md additions" block.

Watch progress with /workflows. When it finishes, present the report to the user. Do not modify CLAUDE.md yourself unless the user explicitly asks you to apply the additions.

What counts as a good candidate

A pattern qualifies only if it is non-obvious (a competent engineer wouldn't guess it from one read), multi-file (needs correlating 2+ locations), not inferable from structure (not from the dir tree, file names, framework conventions, or imports), and not already documented in the current CLAUDE.md. Quality over quantity — zero candidates beats weak ones.
