Session Begin Checklist
⚠️ IMPORTANT - Duplicate Detection:
Before proceeding with the full checklist, check if this session was already started:
- Read the current conversation context - Have I already completed this checklist in the current conversation?
- Check SESSION_CONTEXT.md timestamp - Was "Last Updated" modified today?
- Note: Field stores date only (YYYY-MM-DD), not time. Sub-day duplicate detection relies on conversation context check (#1) and session counter check (#3).
- Check session counter - Did I already increment the session counter earlier in this conversation?
If ANY of these are true:
- ✅ Session is already active
- ⚠️ DO NOT re-run the checklist
- ⚠️ DO NOT re-increment the session counter
- ⚠️ DO NOT re-run startup scripts
- 💬 Example response: "Session #35 already active (started earlier in this conversation). Checklist completed earlier. What would you like to work on?"
If ALL are false:
- ✅ This is a new session
- ✅ Proceed with full checklist below
Before starting any work, complete these verification steps:
0. Secrets Decryption Check (REMOTE SESSIONS)
Check if MCP tokens need decrypting:
# Check secrets status
if [ -f ".env.local.encrypted" ] && [ ! -f ".env.local" ]; then
echo "⚠️ Encrypted secrets found but not decrypted"
fi
If secrets need decrypting:
- Ask the user for their passphrase - Example: "Your MCP tokens need decrypting. What's your passphrase?"
- Run the decrypt command using stdin (avoids shell history exposure):
bash
echo "<user_passphrase>" | node scripts/secrets/decrypt-secrets.js --stdin - Verify success - Check that
.env.localnow exists with tokens - Never store or log the passphrase - Only use it for the decrypt command
Security note: Using --stdin with echo pipe is safer than env vars, which
can leak to shell history and process listings.
If secrets are already decrypted or no encrypted file exists:
- Skip this step and continue to Context Loading
0b. Cross-Session Validation (AUTOMATIC)
The SessionStart hook automatically checks if the previous session ended properly.
If you see a "Cross-Session Warning":
- The previous session started but /session-end was not run
- Consider running the missed session-end checklist items:
- Update SESSION_CONTEXT.md with progress from the incomplete session
- Check for uncommitted changes
- Run
npm run hooks:healthto see session statistics
Quick remediation:
# See session state
npm run hooks:health
# Check for uncommitted work from previous session
git status
git log --oneline -5
0c. Episodic Memory Search (RECOMMENDED)
Search past conversations for relevant context using episodic memory. This helps recover decisions, solutions, and patterns from previous sessions.
Use mcp__plugin_episodic-memory_episodic-memory__search with these
queries:
// Search for context on current work
search({ query: ["current branch/feature name", "decisions"] });
// Search for past errors if debugging
search({ query: "error message or pattern" });
// Search for established patterns
search({ query: ["component/module name", "patterns"] });
When to search:
| Situation | Query Example |
|---|---|
| Starting feature work | ["feature-name", "decisions", "approach"] |
| Debugging an error | "TypeError: Cannot read property" |
| Code review prep | ["module-name", "review", "patterns"] |
| Resuming paused work | ["branch-name", "context", "next steps"] |
Tips:
- Single string = semantic search (fuzzy, meaning-based)
- Array of 2-5 terms = AND search (all terms must match)
- Use
limit: 5for focused results,limit: 20for broader search - Current conversation is NOT indexed yet (only previous sessions)
Summarize findings for the user if relevant context is found.
1. Context Loading (MANDATORY)
- Read SESSION_CONTEXT.md - Current status, active blockers, next goals
- Increment session counter in SESSION_CONTEXT.md
- Check ROADMAP.md for priority changes
1b. Stale Documentation Check (MANDATORY - NEW)
Documentation often drifts from reality. Before trusting any status in docs, verify against actual commits:
# Check recent commits to see actual work done
git log --oneline -30
# Check commits since last documented session date
git log --oneline --since="YYYY-MM-DD"
Compare commits against documented status:
- Look for PR/feature commits (e.g., "feat:", "fix:", "refactor:")
- Cross-reference with ROADMAP.md Active Sprint checkboxes
- If commits show work done but docs show incomplete → UPDATE THE DOCS
Common discrepancies to check:
- Sprint track items: Check commits against Active Sprint checkboxes in ROADMAP.md
- Session counter: Check AI_REVIEW_LEARNINGS_LOG.md version history for session numbers
- Test counts: Run
npm testto verify actual vs documented
If docs are stale:
- Update the stale document with correct status
- Note which sessions failed to update docs
- Commit the corrections before proceeding
2. Consolidation Status Check
Check AI_REVIEW_LEARNINGS_LOG.md for the "Consolidation Trigger" section:
- If "Reviews since last consolidation" >= 10: ⚠️ CONSOLIDATION WAS MISSED
- This means patterns from previous reviews are NOT in claude.md context
- Previous session should have consolidated but didn't
If consolidation was missed:
- Note this in your session summary
- The patterns are still available in AI_REVIEW_LEARNINGS_LOG.md (read if needed)
- Consolidation will happen at THIS session's end
3. Documentation & Planning Awareness
- Check ROADMAP.md Active Sprint section for current work
- Note: Archive files in
docs/archive/are excluded from linting - Completed plans are archived to
docs/archive/completed-plans/ - Reference: INTEGRATED_IMPROVEMENT_PLAN.md is ✅ COMPLETE (archived 2026-01-14)
4. Skill Selection (BEFORE starting work)
DECISION TREE:
├─ Bug/Error? → Use 'systematic-debugging' skill FIRST
├─ Writing code? → Use 'code-reviewer' agent AFTER completion
├─ Security work? → Use 'security-auditor' agent
├─ UI/Frontend? → Use 'frontend-design' skill
├─ Complex task? → Check available skills with /skills
└─ Multi-step task? → Use TodoWrite to track progress
5. Code Review Handling Procedures
When receiving code review feedback (CodeRabbit, Qodo, etc.):
- Analyze ALL suggestions - Read through every comment multiple times
- Create TodoWrite checklist - Track each suggestion as a task
- Address systematically - Don't skip items; mark as resolved or note why skipped
- Verify CI impact - Check if changes affect workflows (ci.yml, docs-lint.yml)
- Test after changes - Run
npm testandnpm run lintbefore committing
6. Anti-Pattern Awareness
Before writing code, scan claude.md Section 4 "Critical Anti-Patterns" and CODE_PATTERNS.md Quick Reference section (🔴 = critical patterns). Key patterns:
- Read before edit - Always read files before attempting to edit
- Regex performance - Avoid greedy
.*in patterns; use bounded[\s\S]{0,N}? - ESLint flat config - Spread plugin configs, don't use directly
- Path-based filtering - Add pathFilter for directory-specific patterns
- Archive exclusions - Historical docs should be excluded from strict linting
7. Session Start Scripts (AUTO-RUN)
Execute these scripts automatically when processing this command:
# Surface known anti-patterns (errors should be visible, not suppressed)
npm run patterns:check
# Check if multi-AI review thresholds reached
npm run review:check
# Surface past lessons relevant to current work
npm run lessons:surface
Important: These scripts are required. If any script fails:
- Note the error in session summary
- Investigate if it's a real issue vs missing script
- If script missing, note it as "N/A" in audit
Record results in session audit - these must be marked as "Ran" or "Failed
(reason)" in /session-end audit.
8. Technical Debt Awareness (NEW - Session #98)
Check current technical debt status:
- Read TECHNICAL_DEBT_MASTER.md for prioritized tech debt
- Note any S0/S1 items that should be addressed this session
- Check if any items from previous session need updating
Key tracking documents:
| Document | Purpose |
|---|---|
TECHNICAL_DEBT_MASTER.md |
Single source of truth for all tech debt |
AUDIT_TRACKER.md |
Audit completion and threshold tracking |
ROADMAP.md Track D |
Performance-critical items for this sprint |
After resolving tech debt items:
- Mark item as resolved in TECHNICAL_DEBT_MASTER.md
- Update ROADMAP.md if item was in a sprint track
- Note in session summary
9. Cross-Document Dependency Check
Before starting work, verify cross-document consistency:
# Check cross-document dependencies
npm run crossdoc:check
Key dependencies to verify:
- ROADMAP.md ↔ SESSION_CONTEXT.md (priorities match)
- TECHNICAL_DEBT_MASTER.md ↔ ROADMAP.md (tech debt section current)
- Audit findings ↔ TECHNICAL_DEBT_MASTER.md (new findings consolidated)
See: DOCUMENT_DEPENDENCIES.md for full dependency matrix.
10. Incident Documentation Reminder
After encountering any significant errors or issues:
- Document the issue in AI_REVIEW_LEARNINGS_LOG.md
- Use the standard "Review #XX" format
- Include: cause, fix, pattern identified, prevention steps
- This builds institutional knowledge for future sessions
