claude-md-drift-check is agent-read markdown (skill) from lstr-1/skills: Use when detecting drift between CLAUDE.md (or AGENTS.md, the Codex CLI alias) / _meta narrative and live repository state. Seven checks: absolute-path resolution, 01-projects/ count claims, issue-reference freshness (closed refs in forward-looking sections), session-file existence, command-count sync (claimed "N commands" vs actual commands/*.md), session-config-parity (top-level keys diffed against docs/session-config-template.md), and vault-dir-parity (CLAUDE.md vs AGENTS.md agreement on vaul.
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
# CLAUDE.md Drift-Check Skill
> **Port note — `unverified` runtime.** This skill references runtime modules under
> `scripts/lib/*.mjs`. Those modules are NOT present in the source plugin directory `sex/`
> and were NOT ported. Every such reference is `unverified`: the agent MUST probe for the
> module at runtime and continue in degraded mode when it is absent. Do NOT assume the module
> exists. Affected modules in this skill: `scripts/lib/config/vault-integration.mjs`.
> The instruction file is alias-resolved per
> [`skills/_shared/instruction-file-resolution.md`](../_shared/instruction-file-resolution.md):
> `CLAUDE.md` (Claude Code / Cursor IDE) wins ties; `AGENTS.md` (Codex CLI) is
> picked up as a transparent alias when `CLAUDE.md` is absent. The resolved
> path and kind are surfaced in the JSON output (`resolved_path`,
> `resolved_kind`).
## Status
PHASE 1 IMPLEMENTED (2026-04-19). Session-end opt-in quality gate. Upstream of `/close` commit preparation, downstream of `vault-sync`.
## Why this exists
…
Pin 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.
