Defame1297 25a6a454b9 feat: add gitleaks secret scanning setup and skill
- scripts/setup-gitleaks.sh — installs gitleaks v8.24.2, seeds
  .gitleaks.toml on first run, writes managed pre-commit hook block;
  re-run replaces block in place without disturbing other hook content
- scripts/gitleaks.toml — base config template extending default ruleset
- .gitleaks.toml — repo config with docs/research/ path allowlist
  (high-entropy terminal captures; v8.24.2 [allowlist] syntax)
- tests/test-setup-gitleaks.sh — 6 behavior tests including stale-block
  replacement and idempotency
- .agents/skills/gitleaks/ — cross-cutting skill covering install,
  update, allowlist tuning, scan modes, and real-finding remediation
- .agents/evals/cross-cutting/gitleaks/eval.yaml — 7 trigger + 3 output
  tests including version-aware allowlist guidance case
- docs/spec/overview.md — updated to reflect new tooling and skill

# Gitleaks allowlist patterns
## Version syntax
| Version | Allowlist syntax |
|---|---|
| v8.24.2 and earlier | `[allowlist]` (singular table) |
| v8.25.0 and later | `[[allowlists]]` (array of tables) |
**Critical**: using the wrong syntax produces no error but the allowlist silently does nothing. Always check `gitleaks version` first.
## v8.24.2 syntax (this repo uses 8.24.2)
### Suppress by path regex
Use for files that can never contain real secrets (research notes, terminal captures, test fixtures, generated docs).
```toml
[allowlist]
description = "research notes and terminal captures"
paths = [
'''docs/research/.*''',
'''tests/fixtures/.*''',
]
```
### Suppress by stopword
Use for placeholder values that match secret patterns but are clearly not real.
```toml
[allowlist]
description = "placeholder values"
stopwords = ["example", "placeholder", "changeme", "your-api-key-here"]
```
### Disable a default rule entirely
Use only when a rule has no value for this repo and produces pervasive false positives.
```toml
[extend]
useDefault = true
disabledRules = ["generic-api-key"]
```
## v8.25.0+ syntax (for reference)
```toml
[[allowlists]]
description = "research notes"
paths = ['''docs/research/.*''']
[[allowlists]]
description = "placeholder values"
stopwords = ["example", "placeholder"]
```
## .gitleaksignore (fingerprint-based — last resort)
```
# Format: <fingerprint>:<line-number>
# Generated by: gitleaks git -v --report-format json | jq -r '.[] | "\(.Fingerprint):\(.StartLine)"'
abc123def456:42
```
Avoid this approach: fingerprints embed line numbers. Any edit to the file shifts line numbers and invalidates the entry, re-surfacing the false positive.
## Verification after any change
```bash
# Scan current files
gitleaks dir -v .
# Scan with debug output to see which allowlists fired
gitleaks dir --log-level debug .
# Scan commit history
gitleaks git -v
# Scan only staged changes (what the pre-commit hook runs)
gitleaks git --staged --redact -v
```
