vault-sync is agent-read markdown (skill) from lstr-1/skills: Use when you need to validate the Meta-Vault's Markdown frontmatter and wiki-link integrity before closing a session or after vault edits. Runs as a hard gate at session-end Phase 1 — blocks close if any `.md` file fails the Zod frontmatter schema or has dangling `[[wiki-links]]`. Supports three modes: `hard` (blocks on errors), `warn` (reports without blocking), `off` (skip). Reads `vault-sync.*` from Session Config; respects per-vault exclude globs from `CLAUDE.md`. Triggers: "vault validation.
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
# Vault Sync 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/peer-cards/schema.mjs`.
> Project-instruction file resolution: `CLAUDE.md` and `AGENTS.md` (Codex CLI) are transparent aliases — see [skills/_shared/instruction-file-resolution.md](../_shared/instruction-file-resolution.md). The vault-marker check below treats either file as a valid marker (when it carries `## Session Config` + `vault-sync:`); references to `CLAUDE.md` resolve via the SSOT precedence rule.
## Status
STATUS: PHASE 1 IMPLEMENTED (2026-04-13). Session-End hard gate (section 3.1) operational. Phase 2 (wave-executor incremental, 3.2) and Phase 3 (evolve advisory, 3.3) not yet implemented.
## Implementation
…
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.
