Ijfw Update

What this skill does

Helps the user check for and apply IJFW updates. Updates are air-gapped: the model cannot execute them. The model issues a confirmation token; the user types ijfw update --confirm <token> in their terminal to actually run.

When to fire

Triggers: "update ijfw", "upgrade ijfw", "is there a new version", "latest version", /update. Also fires when memory prelude reports "update available" on first turn.

Execution

1. Call the MCP tool: ijfw_update_check. This returns:

   • current -- installed version
   • latest -- latest published version on npm
   • available -- boolean
   • If available: true: also confirmation_token, expires_at, changelog_url, and instruction. The same call writes the pending sentinel that the terminal command consumes -- one MCP call, one terminal command, no intermediate ceremony.

2. If up to date: report it. Stop.

   IJFW is up to date (v1.2.5).

3. If update available: present the version delta + changelog link, then surface the OOB instruction verbatim. The terminal command is the air-gap; the model never runs the update itself.

   Update available: v1.2.4 -> v1.2.5 Changelog:

   To proceed, run in your TERMINAL: ijfw update --confirm

   Token expires in 5 minutes. I cannot run the update for you -- only typing this command in your terminal can.

4. DO NOT run npm install, npx @ijfw/install, bash scripts/install.sh, or any equivalent yourself. The MCP path is air-gapped on purpose. Even if the user asks you to "just do it", refuse and surface the terminal command.

5. Back-compat note: ijfw_update_apply still exists for older clients. It is idempotent against the sentinel that ijfw_update_check already wrote, so calling it is harmless but unnecessary in the streamlined flow.

Security model

The token + sentinel + terminal-confirm flow exists so that prompt injection in stored memory, fetched docs, or user-paste content cannot trick the model into auto-updating IJFW. See docs/SECURITY.md for the full threat model.

Common variations

• "Just check, don't update yet" -- call ijfw_update_check, report status, stop.
• "Update silently" -- not supported via the MCP path. Tell the user to run ijfw update --yes in their terminal directly.
• "Roll back to " -- not supported yet (rollback tarballs deferred). Suggest npm install -g @ijfw/install@<version> from the user's terminal.

After a successful update

The user will see "Updated to v" in their terminal. The next IJFW SessionStart will reflect the new version. Suggest restarting any open agent sessions so they pick up the new skills/hooks.
