Startup Diagnostic

Examine all Claude Code startup components — configuration, hooks, MCP servers, indexes, plugins, and filesystem — report PASS/FAIL/WARN for each, and offer fixes for any failures.

Parallelisation Strategy

Batch 1 (may-fail-gracefully — use Bash with 2>/dev/null, NOT Read tool): Steps 1–2 read files that may not exist. A failed Read cascades and kills all sibling parallel calls. Check 5 (graph index) can also ENOENT — include it here.

Batch 2 (reliable — run in parallel): Steps 3–4 and 6–11 query indexes, npm, git, and filesystem. Safe to run together.

Shell gotcha: Never use !! (double-bang) in node -e strings — zsh expands it as history substitution. Use 'key' in obj instead of !!obj.key.

Checks

1. Configuration Files

Check these files exist and parse as valid JSON/markdown:

| File | Check | |------|-------| | CLAUDE.md | Exists at repo root | | .claude/settings.json | Valid JSON, has permissions, plansDirectory | | .claude/settings.local.json | Valid JSON, has hooks and permissions | | ~/.claude/settings.json | Valid JSON (global settings) | | .mcp.json | Valid JSON, all mcpServers entries have command | | .claude/AGENDA.md | Exists (WARN if missing) | | .claude/vault-conventions.md | Exists |

node -e "JSON.parse(require('fs').readFileSync('.claude/settings.json','utf8')); console.log('OK')"

Flag any permission duplicates or contradictions between .claude/settings.json and .claude/settings.local.json.

2. Hook Execution

Test every configured hook can execute without crashing. Pass minimal JSON on stdin, check exit code.

UserPromptSubmit:

echo '{"query":"test"}' | python3 .claude/hooks/secret-detection.py; echo "exit:$?"
echo '{"query":"test"}' | bash .claude/hooks/skill-context-loader.sh; echo "exit:$?"

PreToolUse:

echo '{"tool_name":"Edit","tool_input":{"file_path":"/tmp/test.md","old_string":"a","new_string":"b"}}' | python3 .claude/hooks/file-protection.py; echo "exit:$?"
echo '{"tool_name":"Edit","tool_input":{"file_path":"/tmp/test.md"}}' | python3 .claude/hooks/secret-file-scanner.py; echo "exit:$?"
echo '{"tool_name":"Grep","tool_input":{"pattern":"test"}}' | bash .claude/hooks/graph-search-hint.sh; echo "exit:$?"
echo '{"tool_name":"Bash","tool_input":{"command":"ls"}}' | python3 .claude/hooks/skill-rename-guard.py; echo "exit:$?"
echo '{"tool_name":"Bash","tool_input":{"command":"ls"}}' | python3 .claude/hooks/bash-safety.py; echo "exit:$?"

PostToolUse:

echo '{"tool_name":"Edit","tool_input":{"file_path":"/tmp/test.md"},"tool_result":"ok"}' | python3 .claude/hooks/frontmatter-validator.py; echo "exit:$?"
echo '{"tool_name":"Edit","tool_input":{"file_path":"/tmp/test.md"},"tool_result":"ok"}' | python3 .claude/hooks/tag-taxonomy-enforcer.py; echo "exit:$?"
echo '{"tool_name":"Edit","tool_input":{"file_path":"/tmp/test.md"},"tool_result":"ok"}' | python3 .claude/hooks/wiki-link-checker.py; echo "exit:$?"
echo '{"tool_name":"Edit","tool_input":{"file_path":"/tmp/test.md"},"tool_result":"ok"}' | python3 .claude/hooks/filename-convention-checker.py; echo "exit:$?"
echo '{"tool_name":"Edit","tool_input":{"file_path":"/tmp/test.md"},"tool_result":"ok"}' | python3 .claude/hooks/code-formatter.py; echo "exit:$?"
echo '{"tool_name":"Edit","tool_input":{"file_path":"/tmp/test.md"},"tool_result":"ok"}' | bash .claude/hooks/auto-commit.sh; echo "exit:$?"

Notification (Stop):

python3 .claude/hooks/session-summary.py; echo "exit:$?"

| Result | Status | |--------|--------| | Exit 0 | PASS | | Non-zero exit | FAIL (report stderr) | | ImportError / ModuleNotFoundError | FAIL (missing dependency) | | Timeout (>5s standard, >15s wiki-link-checker) | WARN |

3. MCP Server Connectivity

Test each server from .mcp.json can start and respond:

| Server | Test | |--------|------| | context7 | ToolSearch for context7 tools, trivial query | | memory | ToolSearch for memory tools, call read_graph | | hostinger-mcp | ToolSearch for hostinger tools (auth failure OK — server started) |

Also check plugin MCP servers (MCP_DOCKER for Notion/Diagrams/YouTube) via ToolSearch.

Flag: missing npx package, auth issue, or network problem.

4. SQLite Index (Legacy/Secondary)

sqlite3 .data/vault.db "SELECT COUNT(*) as total FROM notes"
sqlite3 .data/vault.db "SELECT type, COUNT(*) FROM notes GROUP BY type ORDER BY COUNT(*) DESC LIMIT 5"
sqlite3 .data/vault.db "PRAGMA integrity_check"

Check freshness — files newer than the index:

find . -name "*.md" -not -path "./.git/*" -not -path "./node_modules/*" -newer .data/vault.db 2>/dev/null | wc -l

| Result | Status | |--------|--------| | Database missing | WARN — npm run vault:index (secondary index) | | Integrity check fails | WARN — rebuild with npm run vault:index | | >20 files newer than index | WARN — suggest reindex |

Note: SQLite is a secondary index. The primary search index is the Graph index (Check 5).

5. Graph Index (PRIMARY)

Run in Batch 1 (file may not exist — ENOENT crashes Node and cascades to siblings).

ls -la .graph/index.json .graph/search.json 2>/dev/null
node .claude/scripts/graph-query.js --stats 2>/dev/null | head -5

Check freshness — files newer than the graph index:

find . -name "*.md" -not -path "./.claude/*" -not -path "./.obsidian/*" -not -path "./node_modules/*" -not -path "./Templates/*" -newer .graph/index.json 2>/dev/null | head -1

Fallback if graph-query.js --stats is unavailable:

node -e "try{const g=JSON.parse(require('fs').readFileSync('.graph/graph.json','utf8'));console.log('Nodes:',Object.keys(g.nodes||{}).length,'Edges:',(g.edges||[]).length)}catch(e){console.log('MISSING:',e.code||e.message)}" 2>/dev/null

| Result | Status | |--------|--------| | Graph files missing | FAIL — npm run graph:build | | Graph empty (0 nodes) | FAIL — rebuild with npm run graph:build | | >0 files newer than index | WARN — suggest npm run graph:build | | Stats available and current | PASS |

6. Filesystem Structure

for dir in Meetings Projects Tasks ADRs Emails Trips Daily Incubator Forms People Attachments Archive Templates Objectives .claude/skills .claude/context .claude/rules .claude/agents .claude/scripts .data; do
  [ -d "$dir" ] && echo "PASS $dir" || echo "FAIL $dir MISSING"
done

7. Git Health

git status --porcelain | head -20
git stash list
git log --oneline -3

| Symptom | Status | |---------|--------| | Uncommitted .env / credentials | FAIL | | >20 untracked files | WARN | | >5 stale stashes | WARN | | Detached HEAD | WARN |

8. Sandbox Configuration

Sandbox config lives in .claude/settings.local.json (project-level), not ~/.claude/settings.json (global).

Verify .claude/settings.local.json has:

• sandbox.enabled: true
• sandbox.permissions.additionalWritePaths includes /Users/david.oliver/.cache/pre-commit

node -e "const d=JSON.parse(require('fs').readFileSync('.claude/settings.local.json','utf8')); const s=d.sandbox||{}; console.log('enabled:', s.enabled); const paths=(s.permissions||{}).additionalWritePaths||[]; console.log('pre-commit:', paths.some(p=>p.includes('pre-commit'))?'PRESENT':'MISSING')"

Missing pre-commit path causes git hook failures.

9. Plugin Loading

Expected plugins (from ~/.claude/settings.json):

| Plugin | Expected | |--------|----------| | superpowers | enabled | | code-review | enabled | | atlassian | enabled | | compound-engineering | enabled | | claude-md-management | enabled | | ralph-loop | enabled | | hookify | enabled | | claude-code-setup | enabled (global) | | context7 (plugin) | disabled (MCP server used instead) |

Count skills in system-reminder. Significantly fewer than ~150 suggests a plugin failed to load.

10. Skill Files Integrity

# Lowercase skill.md files (should be SKILL.md)
find .claude/skills -name "skill.md" -not -name "SKILL.md" 2>/dev/null

# Total skill count
find .claude/skills -name "SKILL.md" | wc -l

Any lowercase results = FAIL (rename to SKILL.md).

11. Vault-Review Readiness

cat "Daily/$(date +%Y)/Daily - $(date +%Y-%m-%d).md" 2>/dev/null && echo "EXISTS" || echo "MISSING"
cat .claude/AGENDA.md 2>/dev/null && echo "EXISTS" || echo "MISSING"
node .claude/scripts/graph-query.js --type=Task --where="status=active" --count 2>/dev/null || echo "QUERY FAILED"
