# fable-delivery-gate — check the deliverable against its definition of done before handing it over This skill mirrors fablever's `fable_check` gate. In a controlled sim (`eval/comparison/fable-check-sim/`) a definition-of-done gate beat the raw first draft **27–0** and closed the *named* acceptance gap (80.6% vs 12.9%). Honest bound, published in the same file: against a *generic* "make it better" second pass the gate showed **no edge** (16–9, n.s.). So the value is specifically **checking against stated acceptance criteria**, not a general polish step. If the fable-profile MCP is connected (Codex `/mcp`), prefer calling the real `fable_check` tool. This skill is the procedure to follow with or without it. ## When to use this - You are about to present a final external-facing artifact: a report, research summary, doc, marketing or funnel copy, an email to send, a code-change summary a reviewer will trust. - The user says "ship/send/finalize it" or asks "is this ready?" ## When NOT to use this - Mid-draft exploration, or an internal scratch artifact no one will act on yet. - A trivial one-line answer where a formal gate is ceremony. ## Procedure 1. **State the definition of done.** List the acceptance criteria the artifact must meet — from the user's request, the audience, and the medium. If the user never stated them, infer the obvious ones and show them. 2. **Check each criterion against the artifact, concretely.** For each: does the artifact actually satisf...
