SpecStory Guard
A pre-commit guardrail that scans .specstory/history for potential secrets and blocks commits until they are removed or redacted.
How It Works
- Installs a git pre-commit hook in your repository
- Scans
.specstory/historyfiles on every commit - Detects common secret patterns (API keys, tokens, private keys)
- Blocks the commit if secrets are found
- Reports findings with redacted previews for safe review
Why Use Guard?
AI coding sessions may inadvertently capture sensitive data:
- API keys you pasted into chat
- Environment variables in command output
- Private keys or tokens in error messages
- Credentials in configuration examples
Guard prevents accidental commits of these secrets.
Usage
Slash Command
| User says | Action |
|---|---|
/specstory-guard |
Install the pre-commit hook |
/specstory-guard install |
Install the pre-commit hook |
/specstory-guard scan |
Run a manual scan without installing |
/specstory-guard check |
Alias for scan |
/specstory-guard uninstall |
Remove the pre-commit hook |
Direct Script Usage
# Install the pre-commit hook
python skills/specstory-guard/scripts/guard.py install
# Run a manual scan
python skills/specstory-guard/scripts/guard.py scan --root .
# Uninstall the hook
python skills/specstory-guard/scripts/guard.py uninstall
# Scan with custom allowlist
SPECSTORY_GUARD_ALLOWLIST='example-key,PLACEHOLDER_.*' \
python skills/specstory-guard/scripts/guard.py scan --root .
Output
Scan with findings:
SpecStory Guard - Security Scan
===============================
Scanning .specstory/history/...
ALERT: Potential secrets found!
File: .specstory/history/2026-01-22_19-20-56Z-api-setup.md
Line 142: AWS_SECRET_ACCESS_KEY=AKIA...redacted...XYZ
Line 289: private_key: "-----BEGIN RSA PRIVATE KEY-----..."
File: .specstory/history/2026-01-20_10-15-33Z-debug-auth.md
Line 56: Authorization: Bearer eyJhbG...redacted...
Total: 3 potential secrets in 2 files
Commit blocked. Please redact or remove these secrets before committing.
Clean scan:
SpecStory Guard - Security Scan
===============================
Scanning .specstory/history/...
All clear! No secrets detected in 47 files.
Installation success:
SpecStory Guard - Setup
=======================
Pre-commit hook installed at .git/hooks/pre-commit
The hook will now scan .specstory/history/ before each commit.
To test: python skills/specstory-guard/scripts/guard.py scan --root .
Detected Patterns
Guard scans for these common secret patterns:
| Pattern | Example |
|---|---|
| AWS Keys | AKIA..., aws_secret_access_key |
| API Tokens | Bearer ..., token: ... |
| Private Keys | -----BEGIN RSA PRIVATE KEY----- |
| GitHub Tokens | ghp_..., github_pat_... |
| Generic Secrets | password=, secret=, api_key= |
Tuning with Allowlist
If you have false positives (example keys, placeholders), use the allowlist:
# Environment variable (comma-separated regex patterns)
SPECSTORY_GUARD_ALLOWLIST='example-key,PLACEHOLDER_.*,test-token' \
python skills/specstory-guard/scripts/guard.py scan --root .
Remediation
When secrets are found:
- Open the file - Find the line number from the report
- Redact the secret - Replace with
[REDACTED]or remove the line - Re-run scan - Verify the fix with another scan
- Commit - The pre-commit hook will pass
Present Results to User
After running guard commands:
- For install - Confirm the hook is installed and explain what it does
- For scan with findings - List the findings and offer to help redact them
- For clean scan - Confirm no secrets were found
Example Response (findings)
I found 3 potential secrets in your SpecStory history:
1. **AWS credentials** in `2026-01-22_19-20-56Z-api-setup.md` (line 142)
2. **Private key** in the same file (line 289)
3. **Bearer token** in `2026-01-20_10-15-33Z-debug-auth.md` (line 56)
Would you like me to help redact these? I can replace them with `[REDACTED]`
while preserving the rest of the conversation context.
Notes
- Uses no external dependencies (pure Python)
- Hook runs automatically on
git commit - Scan is fast - typically under 1 second for hundreds of files
- Allowlist patterns are regular expressions
