name: vault-mirror
description: 'Use when you need to populate the Meta-Vault with machine-generated notes derived from session-orchestrator JSONL records. Converts entries from `.orchestrator/metrics/sessions.jsonl` and `.orchestrator/metrics/learnings.jsonl` into vault-conformant Markdown under `50-sessions/` and `40-learnings/`. Called automatically at session-end Phase 3.7 and after evolve Phase 3.5 — only when `vault-integration.enabled=true` and `vault-integration.mode != "off"`. Idempotent: re-runs safely; skips hand-authored notes. Triggers: "mirror to vault", "sync session notes to vault", "write learning notes to vault", "vault-mirror failed at session close". <example>Context: session-end is finalizing, vault-integration.mode is "warn". user: "/close" assistant: "Running vault-mirror to write 50-sessions/session-2026-05-17.md from the closing session record — 1 created, 0 skipped."</example>'

# vault-mirror

Read [`skills/vault-mirror/SKILL.md`](../../../skills/vault-mirror/SKILL.md) in full before taking any action, then follow its complete workflow.
The linked document is authoritative, including its prechecks, argument rules, and stop conditions.

Resolve this link relative to this SKILL.md, not the project working directory. The plugin root is three directories above this file. Resolve package paths such as `skills/` and `scripts/` from that root; resolve relative links inside the canonical document from its own directory. Keep the user’s project as the target of project operations.

Regenerate with `node scripts/generate-codex-skills.mjs`.
