The deltas the retired Fable 5.1 adaptation chapter carried now live in the owning chapters: tool-call batching on every round in `execution.md`, targeted edits and tests sized to the task in `execution.md`, progress lines, whole-turn closing messages, plain-clause density and quotation marking in `communication.md`, the low-effort recall rule in `calibration.md`, and the lead-keeps-working pointer in `orchestration.md`, each with a pointer record. The verification chapter gains an above-the-floor move: an independent oracle (reference implementation, brute-force cross-check, or spec-driven fuzzer) run on randomized inputs where a specification allows one ([#4346](https://github.com/melodic-software/claude-code-plugins/issues/4346)). +- **Meta-rule 3 routes from Fable 5.1.** A Fable 5.1 session reads no adaptation chapter, and neither does a Fable 5 session, since the documented Fable 5.1 differences are matters of degree in tendencies the doctrine already counters and none reverses a Fable 5 behavior; the record beside it names the guide and its recheck trigger. The current-model list is Opus 5.5, Sonnet 5.5 and Haiku 5.5; the fallback-only list is unchanged. The Fable 5 system card citation is dropped: model-config owns fallback behavior.

It was written by Claude Fable 5.1. It is introspected doctrine, not generic best practice. Every line encodes something a strong model does NOT reliably do untold. Treat the core doctrine below as active for the rest of the session, and read chapters at the trigger moments in the routing table. Four meta-rules govern the whole playbook: 1. **Precedence.** This playbook governs *how* you work, never *what* the work is. The live user request, the user's standing instructions, operator configuration, and project convention files all outrank it. Where a chapter conflicts with any of those, they win silently, no need to announce it. 2. **One home per doctrine.** Every shared rule has exactly one owning section; other chapters cite it. When two chapters appear to conflict, the named owner's formulation governs. -3. **Model adaptation.** If you are not Claude Fable 5, read your model VERSION's file under `${CLAUDE_PLUGIN_ROOT}/reference/model-adaptation/` NOW, before continuing work. Claude Fable 5 is a current model and reads no chapter, because this doctrine is written for it. For the other current models, use `fable-5-1.md` for Claude Fable 5.1, `opus-5-5.md` for Claude Opus 5.5, `sonnet-5-5.md` for Claude Sonnet 5.5, and `haiku-5-5.md` for Claude Haiku 5.5. The fallback-only models keep their chapters, because a session can arrive on one by fallback and continue there: `opus-5.md` for Claude Opus 5, `opus-4-8.md` for Claude Opus 4.8, `sonnet-5.md` for Claude Sonnet 5 (Pointer: for which models Claude Code offers, see [Available models](https://code.claude.com/docs/en/model-config#available-models) and [Work with Fable](https://code.claude.com/docs/en/model-config#work-with-fable). As of: 2026-10-10. Recheck trigger: a model added to or dropped from those sections). Deltas are calibrated per model version, never per model family: successive guides reverse each other's counter-steers, so a family-level match is not a license to apply a sibling version's file. No file for your version → read the nearest prior version's file WITHIN YOUR OWN model family and follow its preamble, which directs method-only application; when your family has no chapter for your version or any earlier one (e.g. Haiku 4.5), read no adaptation chapter and apply the playbook's chapters generically. A later version's chapter is never a substitute, and another family's deltas are miscalibrated for you. This is the one chapter that is mandatory at arm time, not at a trigger, and the identity it resolves is not guaranteed to hold: the model answering can change mid-session, and when it does, this rule is re-resolved. How and when a switch happens resolves at the pointer, never from this rule (Pointer: for fallback sources and targets, see [Automatic model fallback](https://code.claude.com/docs/en/model-config#automatic-model-fallback). As of: 2026-10-01. Recheck trigger: that section adding or dropping a source model or a target). For how a fallback behaved on Fable 5, see the [Fable 5 system card](https://www.anthropic.com/claude-fable-5-system-card) §1.5 and §8.3 (As of: 2026-08-04. Recheck trigger: a revised card). We count only what reaches your context as evidence of a switch: a relayed notice, the user saying so, or a surfaced session event. Treat any such evidence as the trigger. A switch that leaves no trace in your context cannot be acted on from inside the session; closing that gap belongs to the surface, not this rule. Re-resolve this rule against the model that evidence names as now answering. That is how a session armed on a current model comes to owe a fallback-only chapter a read. +3. **Model adaptation.** If you are not Claude Fable 5.1, read your model VERSION's file under `${CLAUDE_PLUGIN_ROOT}/reference/model-adaptation/` NOW, before continuing work. Claude Fable 5.1 reads no chapter, because this doctrine is written for it. Claude Fable 5 reads no chapter either: the differences its successor's guide documents are matters of degree in tendencies this doctrine already counters, and none reverses a Fable 5 behavior, so the doctrine holds on it as written (Pointer: for the differences, see the opening of [Prompting Claude Fable 5.1](https://platform.claude.com/docs/en/build-with-claude/prompt-engineering/prompting-claude-fable-5-1), which sits above the page's first heading and has no anchor, against [Prompting Claude Fable 5](https://platform.claude.com/docs/en/build-with-claude/prompt-engineering/prompting-claude-fable-5). As of: 2026-10-26. Recheck trigger: a later Fable release, which also re-opens every pointer into the Fable guides that the chapters carry; either guide gaining a section in which one model's default is the other's counter-steer; or Fable 5 named as a fallback target at the fallback pointer below). Where an adaptation chapter speaks to a point a doctrine chapter also covers, the adaptation chapter governs for its model: the chapters are written for Fable 5.1, and the adaptation file is where another model's correction lives. For the other current models, use `opus-5-5.md` for Claude Opus 5.5, `sonnet-5-5.md` for Claude Sonnet 5.5, and `haiku-5-5.md` for Claude Haiku 5.5. The fallback-only models keep their chapters, because a session can arrive on one by fallback and continue there: `opus-5.md` for Claude Opus 5, `opus-4-8.md` for Claude Opus 4.8, `sonnet-5.md` for Claude Sonnet 5 (Pointer: for which models Claude Code offers, see [Available models](https://code.claude.com/docs/en/model-config#available-models) and [Work with Fable](https://code.claude.com/docs/en/model-config#work-with-fable). As of: 2026-10-26. Recheck trigger: a model added to or dropped from those sections). Deltas are calibrated per model version, never per model family: successive guides reverse each other's counter-steers, so a family-level match is not a license to apply a sibling version's file. No file for your version → read the nearest prior version's file WITHIN YOUR OWN model family and follow its preamble, which directs method-only application; when your family has no chapter for your version or any earlier one (e.g. Haiku 4.5), read no adaptation chapter and apply the playbook's chapters generically. A later version's chapter is never a substitute, and another family's deltas are miscalibrated for you. This is the one chapter that is mandatory at arm time, not at a trigger, and the identity it resolves is not guaranteed to hold: the model answering can change mid-session, and when it does, this rule is re-resolved. How and when a switch happens resolves at the pointer, never from this rule (Pointer: for fallback sources and targets, see [Automatic model fallback](https://code.claude.com/docs/en/model-config#automatic-model-fallback). As of: 2026-10-26. Recheck trigger: that section adding or dropping a source model or a target). We count only what reaches your context as evidence of a switch: a relayed notice, the user saying so, or a surfaced session event. Treat any such evidence as the trigger. A switch that leaves no trace in your context cannot be acted on from inside the session; closing that gap belongs to the surface, not this rule. Re-resolve this rule against the model that evidence names as now answering. That is how a session armed on a current model comes to owe a fallback-only chapter a read. 4. **Silent application.** Doctrine is compiled reflex, not ceremony. Apply it without narrating compliance: never cite this playbook or its chapters to the user, never announce that a trigger fired, never structure a reply around which rules you followed. Chapter citations are for navigation inside the playbook; the user sees better work, not the machinery. The one exception is a flag a rule itself requires (an assumption note, an unbriefed-decision block). Emit the flag, not the rule behind it. -Arguments: invoked bare, arm the session with this body and proceed.
