feat: smart-suggest ROI script + hook tuning + guide updates (Mar 16)

Browse source 
- Add examples/scripts/smart-suggest-roi.py: stdlib-only analyzer correlating
  suggestion log with session JSONL files to measure command acceptance rate.
  4 acceptance signals, tier breakdown, daily trend, --json/--since/--no-sessions CLI.
- Tune Aristote smart-suggest hook: tighten 5 over-firing triggers (/tech:commit,
  /tech:sonarqube, /tech:dupes, /check-conventions a11y, /tech:worktree)
- Guide: identity re-injection hook, context engineering maturity grid, code review
  workflow, 1M context window GA update, Spring Break promo, security audit patterns
- Resource evaluations: Nick Tune hooks (3/5), VicKayro security audit (2/5),
  Karl Mazier CLAUDE.md templates, Paul Rayner ContextFlow, Siddhant agent trace,
  Andrew Yng context hub, JP Caparas 1M context window

### Pre-Step: Establish Audit Context
**Before running any checks**, use `AskUserQuestion` to ask:
1. **Environment**: Is this code running in production, staging, or local development?
2. **Scope**: Full audit or specific areas to prioritize?
This is critical for accurate findings:
- **Local dev**: `DEBUG=True`, CORS `*`, HTTP without TLS, `.env` files — all normal. Do NOT flag as vulnerabilities. Mention in an "Before going to production" informational section instead.
- **Staging**: Configs should mirror production. Flag deviations as MEDIUM.
- **Production**: Any misconfiguration is a real finding with full severity.
If the user doesn't answer or is unsure, default to **production** (conservative).
---
### Phase 1: Configuration Security (via /security-check)
Execute all checks from `/security-check` (the `examples/commands/security-check.md` command). This covers:

}
```
**Anti-false-positive rule — MANDATORY before reporting any secret finding:**
Before raising a secrets finding, run these verification commands:
```bash
# 1. Verify .env is actually in .gitignore (if yes, local .env is NOT a finding)
grep -n '\.env' .gitignore 2>/dev/null || echo ".env NOT in .gitignore"
# 2. Verify secrets were actually committed (empty output = no finding)
git log --all -p -- '*.env' '*.key' '*.pem' '*.secret' 2>/dev/null | grep -E '^\+.*(password|secret|api_key|token)' | head -20
# 3. Check git history for provider-specific patterns
git log --all -p 2>/dev/null | grep -E '^\+(sk-[a-zA-Z0-9]{20,}|AKIA[A-Z0-9]{16}|ghp_[a-zA-Z0-9]{36})' | head -10
```
Only report a secret finding if you have **concrete proof from these commands**. A `.env` file present locally is not a finding if it's in `.gitignore`. Never report "secrets may be exposed" based on pattern matching alone.
**Scoring:**
- 0 secrets found → +20 points
- 1-3 secrets → +10 points

#!/bin/bash
# .claude/hooks/identity-reinjection.sh
# Event: UserPromptSubmit
# Non-blocking guard: re-injects agent identity if context compaction erased it
#
# Problem: When Claude compacts context during a long session, agents configured
# with a specific role (team lead, reviewer, etc.) can "forget" their identity.
# The compacted transcript no longer contains the original system instructions.
#
# Solution: Store identity in a file. After each user message, check whether the
# last assistant response includes the expected identity marker. If not, inject
# the identity as additionalContext so the next response re-establishes the role.
#
# Setup:
# 1. Create .claude/agent-identity.txt with your agent's identity instructions
# 2. Set IDENTITY_MARKER to a short string that should appear in agent responses
# (e.g. "LEAD:", "REVIEWER:", "DEVELOPER:")
# 3. Wire this hook to UserPromptSubmit in settings.json
#
# Output format: UserPromptSubmit additionalContext injection
# Properties:
# - Silent no-op when identity is present (zero overhead)
# - Silent no-op when no identity file configured
# - Never blocks — exits 0 in all cases
# - Compatible with agent teams (SubagentStart, SubagentStop) and solo sessions
