Fable Code Review
Request a read-only, precision-first review in an isolated Fable context.
Workflow
- Use Bash to read
CLAUDE_CODE_SUBAGENT_MODEL. If it is set to anything other than inherit, fable, or a claude-fable-* model ID, abort before launching: this environment variable has higher precedence than the skill's model request.
- Run
git status --short, git diff, and git diff --cached.
- Include untracked files the user wants reviewed with
git add -N <path> so their contents appear in the diff without staging them.
- If the combined diff is empty, report that there are no changes to review.
- Read the root and file-scoped
CLAUDE.md files plus any ADRs cited by changed code.
- Launch the
fable-reviewer agent with the per-invocation model set to fable, plus the diff and a compact context brief containing the changed files, applicable conventions, referenced ADRs, and the user's requested review focus.
- If the Agent tool reports a fallback or model-availability error, abort instead of returning its findings as a Fable review.
- Return the agent's validated findings without adding unverified issues. State that Fable was requested but the resolved model was not independently verified, because Claude Code does not expose the resolved subagent model to skills and an organization
availableModels policy can silently fall back to the inherited model.
The fable-reviewer agent's model: fable frontmatter and the launch-time model: "fable" argument both request Fable. Do not substitute another reviewer or route this skill through an external MCP provider. Never claim the runtime-selected model was verified when Claude Code did not expose it.
