YQ Toolchain Update

Maintain the fixed local helper-tool list in tool-registry.json. This Skill manages ordinary third-party command-line tools; use skill-lifecycle-manager separately for Skills' own sources, installs, and upgrades.

Required first response

Run scripts/toolchain-audit.ps1 -Mode Inventory before any update. Show the user the complete table of every selected tool, not only a count. Include its group, installed/not-installed state, observed version output, update source, and a short plain-language reason for the recommended order.

The registry is the single source of truth for the fixed list and its three groups: collaboration and cloud; browser, MCP, and search; content platforms. Show exact tool names only from the inventory output, so the entrypoint does not become a stale second copy.

Do not add Codex, Node, Python, Git, Docker, Bun, pnpm, uv, or other general runtimes unless the user explicitly asks.

Confirmation gates

1. After showing the complete list and current state, get explicit approval for group 1.
2. Before a group, show the full list for that group, available stable updates, and likely effect in non-technical language.
3. Update one tool at a time with its source-native method from the registry. Verify its version and basic command before starting the next tool.
4. At the end of a group, show a complete result table: updated, already current, skipped, or blocked. Stop and get explicit approval before the next group.
5. Stop immediately for interactive login, authorization, configuration migration, or a failed validation. State exactly what needs the user's decision; never silently skip it or continue to another group.

Use stable releases only. Never run unbounded bulk updates such as a bare npm update -g or winget upgrade --all.

Safe update rules

• Verify the official source and current stable version immediately before an update. Record the old and new version.
• Preserve existing credentials, cookies, profiles, and user configuration. Do not print their contents.
• Use package-manager readback plus a non-authenticated --version or --help check after each change.
• If a PowerShell function or alias has the same name as a registry executable, report the conflict and use the verified application path for the probe. Do not run a shadowing function as if it were the registered tool.
• For Playwright, update only the browser engines already installed unless the user asks for another browser. Do not alter the user's Chrome profile or login state.
• Agent Reach can route to other tools but does not own their installations. Update its integrations as separate registry entries.
• For LinkedIn, first search active Codex/Claude MCP configuration paths without printing secrets. Only replace a legacy server command after finding a real reference and receiving confirmation. If none is active, install and validate mcp-server-linkedin, leave the legacy command as a rollback path, and do not create a new MCP configuration.

Reporting

Keep reports simple. List every requested tool by name, including ones already current. Separate observed facts from unverified account health. End a completed three-group run by asking whether the user wants the registry or this Skill changed; do not change either automatically.
