Agent & Automation Guide
Zero-dependency, machine-first security tooling for autonomous coding agents, Model Context Protocol (MCP) servers, pre-commit diff hooks, and CI/CD pipelines.
01
Headless & Machine CLI
All five tools implement a strict headless contract for programmatic integration into agent toolkits, shell pipelines, and background watchers.
Standard Flags
--format json emits structured schemas; -q, --quiet silences stdout for clean exit status; -v prints stderr diagnostics; -o <FILE> writes directly to disk.
Tri-State Exit Codes
0 = Success / Clean verdict (safe to ship); 1 = Security findings / Policy threshold breached (BLOCK/FIX); 2 = Argument parse error or runtime I/O failure.
# Stream staged diff directly to snip in machine-readable JSON:
git diff --staged | snip audit --format json
# Silent gate assertion (exits 0 on clean, 1 on violation):
git diff --staged | snip audit -q || echo "Security violation detected"
02
Model Context Protocol (MCP)
Run snip serve --mcp to expose real-time diff auditing and security gates directly to Claude Desktop, Cursor, and Windsurf via stdio.
// claude_desktop_config.json or ~/.cursor/mcp.json
{
"mcpServers": {
"snip": {
"command": "snip",
"args": ["serve", "--mcp"]
}
}
}
03
Agent Rules & Prompts
Drop these directives into your project's .cursorrules, CLAUDE.md, or agent system prompts to enforce automated security gates:
# studio2201 Autonomous Security Rules
- Before staging any code modifications, audit diffs: git diff --staged | snip audit --format json
- If Snip emits exit code 1 (Block/Fix): remediate leaked secrets, broken RLS, or permissive CORS.
- When adding dependencies to package.json, Cargo.lock, or pyproject.toml: vigil policy check --max-dormancy 180 -q
- Reject dormant packages; verify cryptographic call sites comply with post-quantum standards via aegis.
04
CI/CD & Pre-Commit Pipelines
Gate code modifications locally before commits are created and continuously in pull request workflows.
#!/bin/sh
# .git/hooks/pre-commit — Local pre-commit diff gate
git diff --staged | snip audit -q || {
echo "[-] Snip pre-commit gate failed: security violations found in staged diff." >&2
exit 1
}

5-Tool Automation Matrix
How the five studio2201 tools integrate across the autonomous developer loop.
Snip vibe-code
Loop Phase: Code generation & pre-commit diff review.
Command: git diff --staged | snip audit
Exit Codes: 0 Ship · 1 Block/Fix · 2 Error.
Action: Strips leaked API keys, fixes broken Supabase RLS, and remediates permissive CORS.
Vigil dormancy
Loop Phase: Manifest updates & dependency addition.
Command: vigil policy check --max-dormancy 180 -q
Exit Codes: 0 Pass · 1 Dormant dep · 2 Error.
Action: Halts PRs on abandoned crates/packages; suggests actively maintained alternatives.
Aegis pqc sdk
Loop Phase: Cryptographic migration & compliance sweeps.
Command: aegis scan --format json ./src
Exit Codes: 0 Compliant · 1 Classical crypto · 2 Error.
Action: Scans RSA/ECC and emits OMB M-26-15 roadmaps with ML-KEM-768/ML-DSA-65 drop-in shims.
Proven attestor
Loop Phase: Build, packaging & artifact release.
Command: proven attest target/app --format slsa -o app.slsa.json
Exit Codes: 0 Verified · 1 Tampered · 2 Error.
Action: Signs binaries with post-quantum ML-DSA-65; attests bit-identity before runtime deployment.
Boneyard tech-debt
Loop Phase: Fleet governance & scheduled org audits.
Command: boneyard enrich -i repos.json --format json
Exit Codes: 0 Compliant · 1 Debt breach · 2 Error.
Action: Ranks multi-repo catalog across 5 axes; allocates remediation budgets in repo-weeks.
