description	This skill should be used when the user asks to "run lcm dogfood", "self-test lcm", "validate lcm build", "test lcm hooks", "check lcm mcp tools", or mentions lcm QA, regression testing, or pre-release validation. Runs a comprehensive 39-check self-test across all CLI commands, hooks, MCP tools, and resilience.

lcm Dogfood — Live Self-Test Suite

Comprehensive self-test for the lcm system in a live Claude Code session. Covers all 9 CLI commands, 4 hooks, 8 MCP tools, and resilience scenarios across 39 checks in 10 phases.

Arguments: all (default), health, import, compact, promote, sensitive, pipeline, hooks, mcp, resilience, debug

Procedure

Execute each phase in order (or just the requested phase). For each check:

1. Run the command or verify the condition
2. Record: ✅ PASS, ❌ FAIL, or ⚠️ SKIP (with reason)
3. On FAIL: capture error, check daemon logs (~/.lossless-claude/daemon.log), continue
4. Produce the Scorecard at the end
5. Write failures to .xgh/reviews/dogfood-YYYY-MM-DD.md

Routing: Use ctx_execute (context-mode sandbox) for commands producing large output. Use Bash for short-output commands. Use MCP tools directly for Phase 8.

Consult references/checks.md for detailed pass/fail criteria for each check.

Phase Overview

#	Phase	Checks	What it tests
1	Health	3	Daemon status, doctor, version
2	Import	3	Transcript ingestion + idempotency
3	Compact	3	Summarization + idempotency
4	Promote	2	Insight extraction + stats consistency
5	Sensitive	5	Pattern list/test/add/remove cycle
6	Pipeline	2	Full curate + diagnose
7	Hooks	6	Wiring verification + live tests
8	MCP	8	All 7 MCP tools + store-retrieve roundtrip
9	Resilience	3	Kill/restart/graceful degradation
10	Debug	4	Logs, PWD, DB existence, integrity

Key Commands

All CLI checks use node dist/bin/lcm.js <subcommand>. If lcm is on PATH, use that instead.

Hook Verification

Hooks are registered in .claude-plugin/plugin.json, NOT ~/.claude/settings.json. Verify all 4:

• SessionStart → lcm restore
• UserPromptSubmit → lcm user-prompt
• PreCompact → lcm compact --hook
• SessionEnd → lcm session-end

For live hook testing, pipe JSON to stdin:

echo '{}' | node dist/bin/lcm.js restore

The UserPromptSubmit hook requires prompt and cwd fields:

node -e 'console.log(JSON.stringify({prompt:"test query",cwd:process.cwd()}))' | node dist/bin/lcm.js user-prompt

MCP Tool Testing

Call lcm MCP tools directly from the session. All 8 tools to test: lcm_doctor, lcm_stats, lcm_search, lcm_grep, lcm_store, lcm_expand, lcm_describe + store-retrieve roundtrip.

| **TOTAL**   | **39** |         |         |               |

For ❌ FAIL items, include: error message, daemon log excerpt, suggested fix. For ⚠️ KNOWN items, reference the bug number from references/known-issues.md.

Scripts

Utility scripts for checks that require custom logic:

• scripts/prompt-search-test.js — Test the daemon /prompt-search endpoint directly. Usage: node scripts/prompt-search-test.js "query" [cwd]
• scripts/db-integrity.js — Check PRAGMA integrity_check on all project databases. Usage: node scripts/db-integrity.js
