This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
ai-coding-agent-guardrails from francostino/opencode-skills-collection is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add francostino/opencode-skills-collection/ai-coding-agent-guardrails@v1.0Pins v1.0 in mdr.lock. Pin the fingerprint instead.

Secure AI coding agents (Claude Code, Cursor, Codex, Copilot) with permission.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AI Coding Agent Guardrails Secure the use of AI coding agents across engineering teams. This skill covers permission boundaries, secret protection, sandbox isolation, code review gates, and audit trails for Claude Code, Cursor, Copilot, and Codex. --- ## Permission Boundaries ### CLAUDE.md Configuration Create a `CLAUDE.md` at the repository root to restrict Claude Code behavior: ```markdown # CLAUDE.md ## Restrictions - NEVER read or output contents of .env, .env.*, secrets.yaml, or any file matching *.pem, *.key - NEVER execute `rm -rf`, `DROP TABLE`, `kubectl delete`, or `terraform destroy` commands - NEVER push directly to main or master branches - NEVER modify files in the infrastructure/, terraform/, or .github/workflows/ directories without explicit user approval - NEVER install new dependencies without listing them first for review - NEVER access or display API keys, tokens, passwords, or connection strings ## Allowed Operations - Read and modify application source code in src/, lib/, and tests/ - Run test suites with `npm test`, `pytest`, `go test` - Run linters with `eslint`, `ruff`, `golangci-lint` - Create new branches with prefix `ai/` or `agent/` …

How to install
mdr add francostino/opencode-skills-collection/ai-coding-agent-guardrails@sha256:0de7f7a1bb34ab9dThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
