10 Agent Skills built specifically for Claude Fable 5 — intent, boundaries, and verification hooks instead of the step-by-step micromanagement older-model skills relied on. See skills/ for the individual skill files.

act-when-ready

Stop Claude Fable 5 from over-planning, re-deriving settled facts, or surveying options it will never pursue. Use in any interactive or agentic session where responses feel slow, turns run long on simple asks, or the model keeps restating context before acting. Especially valuable at high effort settings and in ambiguous, multi-threaded requests.

autonomous-continuation

Keep Claude Fable 5 running to completion in unattended pipelines — no stopping on a statement of intent, no mid-run permission questions, no self-imposed session splits over context worries. Use for overnight runs, scheduled jobs, CI agents, and any harness where nobody is watching to type "continue".

effort-calibrator

Choose and tune the effort setting for Claude Fable 5 workloads. Use whenever the user asks which effort level to use ("what effort should this batch job run at?", "is xhigh worth it here?"), complains that Fable 5 is slow or expensive, wants to cut latency or token cost, designs a pipeline/harness that mixes routine and hard tasks, or reviews API code that sets output_config.effort.

grounded-progress

Make Claude Fable 5 progress reports verifiable against actual tool results during long autonomous runs. Use for any multi-hour or overnight agent session, scheduled pipelines, CI agents, or whenever the user has been burned by status updates claiming work that wasn't done. Apply before launch, not after a fabricated report appears.

markdown-memory

A file-based lesson memory that Claude Fable 5 reads and maintains across sessions. Use for any recurring agent (daily jobs, long projects, team assistants) where the same corrections keep being re-made, and when bootstrapping a new agent from past session history. Fable 5 benefits from recorded lessons noticeably more than prior models did.

no-gold-plating

Keep Claude Fable 5 changes minimal — no unrequested refactors, abstractions, defensive code, or feature creep. Use in code review, bug fixes, and any coding session where diffs come back bigger than the ask, with extra helpers, error handling, or "while I was here" cleanup. Particularly important at high and xhigh effort.

regrounding-summary

Make Claude Fable 5's final report readable to someone who saw none of the work. Use for long agentic sessions, overnight runs, and multi-tool tasks — whenever summaries come back as arrow-chain shorthand, invented abbreviations, or references to reasoning the reader never saw. Pair with grounded-progress for status content; this skill governs the prose.

scope-guard

Prevent Claude Fable 5 from taking unrequested actions — applying fixes when only asked to diagnose, sending or drafting messages nobody asked for, creating backup branches, or running state-changing commands on thin evidence. Use in ops/debugging sessions, shared environments, production-adjacent work, and any conversation where the user thinks out loud.

skill-refactorer

Audit and rewrite existing agent skills, system prompts, and CLAUDE.md files for Claude Fable 5. Use whenever the user mentions migrating, upgrading, porting, or "fixing" a skill or prompt for Fable 5, complains that a previously good skill now produces worse output, or asks why Fable 5 ignores or over-follows old instructions. Also trigger when reviewing any skill written before June 2026.

subagent-orchestration

Patterns for delegating work to parallel subagents with Claude Fable 5 — when to split tasks, async coordination, long-lived workers, and fresh-context verifiers. Use when designing multi-agent harnesses, when a large task has independent parts, when runs bottleneck on sequential steps, or when self-review keeps missing its own mistakes.
