fable-method-harness

Operating harness for working on the method-harness-compiler project (or reviewing its artifacts). Use when starting ANY task on that project — phase reviews, tool discovery, PR review, eval design, memory updates, runtime export, repo maintenance, or A/B test design. Routes the agent to a minimal per-task file set instead of whole-repo reading. For work on ANY OTHER project, activate only when the task is long / multi-step, multi-agent, expensive-if-wrong, makes a completion claim (done / passing / fixed / ready / safe / staged), or touches governance (permissions, hooks, cron, CI, routing) — the portable entry is then core/GLOBAL_BOOTSTRAP.md. Skip for one-line / typo / format edits and pure capability asks.

Use this skill when auditing, simplifying, benchmarking, or refactoring an AI/agent project harness, including CLAUDE.md, AGENTS.md, slash commands, skills, subagents, hooks, tool routing, scheduled reviews, AI-review reports, benchmark scaffolds, and rolling harness maintenance. Not for ordinary code review of application code (use code-review) or for running the method-harness-compiler project (use the root harness ladder).
