agent-instructions skillA
agent-instructions is agent-read markdown (skill) from devantler-tech/agent-skills: Architect a repository's AI-agent instruction files so one canonical source drives every tool without drift — AGENTS.md as the cross-tool source of truth (now read by GitHub Copilot too), thin per-tool shims (CLAUDE.md, GEMINI.md) that include it, and optional path-scoped .github/instructions/ rules. Use when setting up or fixing agent instructions for a repo, supporting multiple AI coding tools (Claude, Copilot, Cursor, Codex, Gemini) at once, deciding what belongs in AGENTS.md vs a tool-specif.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Agent Instructions Most AI coding tools read project guidance from a file in the repo — historically each looked in a *different* place (`AGENTS.md`, `CLAUDE.md`, `.github/copilot-instructions.md`, …). Copy the same guidance into each one and the copies **drift**: a command changes in one file and the others keep telling agents the old way. The fix is one **canonical** source plus thin tool-specific **shims** (which include the canonical file). Keep all durable guidance in the canonical file; keep only genuine tool-specific quirks in a tool's own file. The good news: `AGENTS.md` is now read by nearly every major tool — **including GitHub Copilot** — so the "one canonical file" ideal is finally achievable without a per-tool copy. ## The canonical file: `AGENTS.md` `AGENTS.md` is the cross-tool standard — a plain-Markdown file at the repo root, read natively by a growing set of agents and editors (Codex, Cursor, Gemini CLI, and GitHub Copilot). Make it the **single source of truth** for everything durable and tool-neutral: - **What the project is** — one-paragraph purpose, the stack, where the important code lives. …

How to install
mdr add devantler-tech/agent-skills/agent-instructions@git:20260711.658f1d1mdr add devantler-tech/agent-skills/agent-instructions@sha256:55afa043450c8a14Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
