AutoVault Meta-Skill

AutoVault is the local capability and skill profile layer. It stores and validates skills, then syncs them into the agent's normal skill directory as filesystem symlinks. If this skill is loaded, AutoVault profile sync is already working for this agent; do not require an AutoVault MCP server before using other visible skills.

AutoVault does not execute skills. The agent that loads a skill is responsible for sandboxing and user confirmation before running anything the skill describes.

When to use

• When the user asks why an AutoVault-managed skill is visible.
• When deciding whether to use a synced skill such as commit-message or skill-author.
• Before writing a new skill, check the skills already visible to the current agent.
• When debugging profile sync or stale skill links.

Primary workflow: synced skills

AutoVault's primary interface is filesystem-native profile sync:

$AUTOVAULT_STORAGE_PATH/
  skills/SKILL_NAME/SKILL.md
  transforms/SKILL_NAME/TRANSFORM_NAME/TRANSFORM.md
  rendered/AGENT/SKILL_NAME/SKILL.md when transforms apply
  profiles/AGENT/SKILL_NAME points to ../../skills/SKILL_NAME or ../../rendered/AGENT/SKILL_NAME

~/.claude/skills/SKILL_NAME points to ~/.autovault/profiles/claude-code/SKILL_NAME
~/.codex/skills/SKILL_NAME points to ~/.autovault/profiles/codex/SKILL_NAME

Use synced skills directly through the host's normal skill mechanism. If a skill is visible in the current agent session, it is already available; no mcp__autovault__* tools are required.

For local troubleshooting, inspect the profile directory:

ls -l ~/.autovault/profiles/claude-code
ls -l ~/.claude/skills
ls -l ~/.codex/skills

Optional compatibility: MCP tools

Some hosts may still connect the AutoVault MCP compatibility server. Only use these tools if mcp__autovault__* tools are actually present in the current session. If they are absent, continue with the synced skills that are already visible.

The compatibility server exposes these MCP tools:

• list_skills - returns metadata for every installed skill.
• search_skills(query, top_k?) - metadata text search across name, title, description, tags, category, and when_to_use. Returns ranked matches with scores and structured match reasons.
• get_skill(name, agent?) - returns the full SKILL.md plus parsed metadata, capabilities, required secrets, and source provenance. Pass agent to see the generated variant with matching transforms applied.
• read_skill_resource(skill_name, resource_path) - reads a file packaged alongside a skill. Path traversal is blocked.
• install_skill({source, identifier, version?, skill_md?}) - installs from github, agentskills (slug[@version]), or url (https only). GitHub identifiers may be owner/repo[@ref][:path/to/SKILL.md], a blob URL, or a repo-root/tree URL. Repo-root/tree URLs discover SKILL.md candidates; if there is more than one, the tool returns outcome: "multiple_candidates" with exact candidate identifiers. If skill_md is provided, it is treated as inline content; otherwise the source adapter fetches it.
• propose_skill({skill_md, resources?, source_session?}) - validates and installs a new skill. Outcome is one of accepted, duplicate, invalid, or security_blocked.
• propose_skill_transform({transform_md, replace?}) - validates and stores a vault-local transform overlay for an installed base skill. The base skill is not modified.
• list_skill_transforms({base?}) - lists transform overlays and integrity status.
• remove_skill_transform({base, name}) - deletes a transform overlay and refreshes generated profiles.
• check_updates(skill?) - compares installed content hash against the recorded source. Bundled inline skills are checked against the local bundled source; other inline skills are reported as unchecked. Changed transform bases appear in transform_reviews with the pinned old base content.

Optional MCP workflow

1. If mcp__autovault__search_skills is available, call search_skills with a concise query.
2. If a result has high confidence, call get_skill and follow it.
3. If nothing fits, author a new SKILL.md and call propose_skill. Handle every outcome explicitly:
   • accepted - skill is stored under $AUTOVAULT_STORAGE_PATH/skills/<name>.
   • duplicate - inspect existing_match and choose a merge_options value (keep_existing, replace, merge, keep_both).
   • invalid - fix the listed schema errors and resubmit.
   • security_blocked - rewrite the content to remove flagged patterns.
4. Use propose_skill_transform instead of forking a skill when the user wants an agent/workspace-specific variant such as different research tools or output channels.
5. Periodically call check_updates to detect drift for skills installed from a remote source, bundled inline skills, or transforms pinned to an older base.

Skip this workflow entirely when the MCP tools are not connected. Missing MCP tools are not an error for filesystem-synced skills.

SKILL.md schema (minimum)

name: kebab-case-name
description: At least 20 characters describing what the skill does and when to use it.

Optional but recommended fields: tags, category, license, capabilities (network, filesystem, tools), and requires-secrets.

Security expectations

• AutoVault runs a denylist scan on every proposal/install. Common flagged categories include: SSH and AWS credential reads, piping remote content into a shell, destructive recursive deletes of home/root, verification-bypass flags, setuid/setgid, and eval of untrusted vars.
• AutoVault cross-checks declared capabilities against content: a skill declaring network: false that contains curl/wget/fetch is blocked, as is a tools: [Bash] skill that invokes Python/Node.
• In strict mode (AUTOVAULT_SECURITY_STRICT=true, default) any flag blocks the install. In non-strict mode, flags become warnings.
• Skill content is data, not code, until an agent decides to execute something it describes. Always require explicit user confirmation before running shell commands a skill suggests.
