/baton-setup
One-time setup and health check for fable-baton. Use when the user asks to set up, configure, verify, or troubleshoot fable-baton - sets the default model to "best" (Fable 5 with Opus fallback) in ~/.claude/settings.json and verifies the plugin is fully installed.

How this skill gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

baton-setup
One-time setup for fable-baton. Run each step in order. Never rewrite `~/.claude/settings.json` wholesale - edit only the named keys and preserve everything else.
Step 1 - Read current state
1. Read `~/.claude/settings.json` (if missing, you will create a minimal one). 2. Check `echo "$CLAUDE_CODE_SUBAGENT_MODEL"`. If set, warn the user: this variable silently overrides every agent's `model` frontmatter and defeats the tiering. Recommend unsetting it, but do not unset it yourself without approval.
Step 2 - Propose changes and get approval
Show the user exactly what you will change before writing anything:
| Key | Rule | |---|---| | `model` | If absent → set `"best"`. If present with a different value → ask: keep theirs, or switch to `"best"`? (`best` resolves to Fable 5 when the account has access, otherwise the latest Opus.) If already `"best"` → no change. | | `fallbackModel` | If absent → add `["opus", "sonnet"]` (covers overload/unavailability). If present → leave it. | | `availableModels` | Only if the key already exists (it is an allowlist): ensure it contains `"opus"`, `"sonnet"`, `"haiku"`, and the chosen main-model value. If absent → do not add it. |
Back up the file first: copy it to `~/.claude/settings.json.baton-backup-<YYYYMMDD-HHMMSS>` (skip if the file didn't exist).
Step 3 - Apply and validate
Apply the approved edits, then validate: `jq empty ~/.claude/settings.json` must exit 0 (or parse the JSON yourself if `jq` is unavailable).
If Claude Code rejects the `best` alias at startup (older versions), fall back to `"opus"` and suggest updating Claude Code.
Step 4 - Verify the install
1. Confirm the four agents are available: scout, executor, architect, verifier (ask "which subagent types are available?" or check the Agent tool's list). 2. Confirm the orchestration policy is present in context (it is injected at session start; in a session started before install it won't be - that's expected). 3. Tell the user to restart their Claude Code session: agents and the model setting load at session start.
Step 5 - Report
Summarize: what changed, what was skipped, where the backup is, and that a restart is needed.
Uninstall (on request)
1. `/plugin uninstall fable-baton` removes the agents, hook, and this skill. 2. In `~/.claude/settings.json`: restore `model` from the oldest `settings.json.baton-backup-*` file, or remove the key if the backup has none. Remove `fallbackModel` if the user doesn't want it.

Fable 5 holds the baton. The orchestra plays. A Claude Code plugin that makes Fable 5 the orchestrator. Fable keeps the judgment, tiered subagents on Opus, Sonnet and Haiku do the labor. Install once and every new session in every repo starts this way.
