playbook skillA
playbook is agent-read markdown (skill) from rylaa/fable5-opus5-orchestrator: Orchestrator playbook — the full delegation contract (research pipeline, worker report contract, spawn economics, forks, teammate lifecycle, chair hygiene). The chair MUST load this before its first delegation of every session; the injected core profile only summarizes it..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

Every ambiguity you leave in a spawn prompt becomes a guess committed to code, so the brief carries what the worker would otherwise have to invent: - the goal in one sentence, and what "done" looks like - the files or areas it owns, and what it must NOT touch - constraints that are not visible in the code (a contract another team parses, a deadline, a decision already made) - what to do when it hits something unexpected: report and stop, or decide and note it - the exact deliverable — a diff, a brief, a path If a choice would change the work and only the user can settle it, ask the USER before spawning. One question, in the same message as whatever else you can get done without the answer. ## Research pipeline — parallel fan-out, no mid-flight dumps YOU pick the questions and sources — never a fetch worker. ONE sonnet (`medium`) per source: it fetches the source VERBATIM to …
