description: First run after cloning the engine — create and fill CLAUDE.local.md and identities.local.md by interview, set the session model (Fable), offer the global git identity guard; never overwrites, runs no git operation
disable-model-invocation: true

Prepare this instance of the forge (POS.1050). Run after cloning the
engine, before any other work. Two files in the engine — plus, on the
user's word, the git identity configuration outside it; the command
runs no git operation.

The conversation language is not configured yet on a true first run:
speak whatever language the user speaks to you.

1. **`CLAUDE.local.md`** at the engine root.
   - If it already exists: report briefly what it holds and do not
     touch it.
   - Otherwise copy `templates/CLAUDE.local.md` to the root and fill
     it by elicitation interview, one question at a time, the
     language first so that every later question arrives in it:
     - **Conversation language** — the language the working
       conversation runs in (the template says what follows it);
     - **Principal** — the role, whose thinking is being forged (the
       template's placeholder);
     - **Git identities** — name and e-mail per git host the user
       will push to (e.g. github.com, a company host), written to
       `identities.local.md` beside it from
       `templates/identities.local.md` — the roster of CLAUDE.md,
       Persistence. May be left empty and added later; say so.
   - Keep the templates' format; both files are gitignored and never
     committed.
   - Close the git-identities part with the offer of the global
     guard (CLAUDE.md, Persistence): `user.useConfigOnly = true`
     under `[user]` in `~/.gitconfig`, appended on the user's word —
     read the file first, never overwrite existing content. Where
     `~/.gitconfig` carries a global `user.name` or `user.email`, say
     the guard only bites once that identity is removed, and offer
     the removal — again only on the user's word. Declined: print the
     lines for the user to apply by hand. This is the one edit
     outside the engine; it is a configuration text file, not a git
     operation.
2. **`.claude/settings.local.json`**.
   - If it already exists: report the model it names and do not touch
     it.
   - Otherwise create it with `{ "model": "fable" }` and tell the
     user in one sentence: the session is set to Fable — the
     strongest available model, which the whole forge including the
     blind reviewers runs on — and it can be changed at any time with
     `/model` or by editing this file. A notice, not a question.
3. Finish by pointing at the next step from the Quickstart: start a
   new project with `/new-project <slug>`, or bring an existing one
   with `/import-project <git-url>`.
