review-agent-harness from majiayu000/spellbook is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add majiayu000/spellbook/review-agent-harness@git:20260812.ed81572Pins git:20260812.ed81572 in mdr.lock. Pin the fingerprint instead.

Review whether a repository's coding-agent harness can reliably carry work from intent through controlled execution, verification, delivery, and learning. Use when asked to assess agent readiness, repeated agent failures, Rules/Skills/Hooks/Memory effectiveness, missing validation or recovery loops, or whether a harness repair improved later outcomes. Do not use for code-only audits, AGENTS-only audits, individual skill reliability reviews, or executing the task itself.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Review Agent Harness Review the operating system around coding agents, not only its files. Separate declared assets, reachable routes, observed task use, and later outcomes. ## Route And Scope Resolve the directory containing this `SKILL.md` before running its scripts. Select one mode: - `static`: inspect the target repository only. Use by default. - `episode`: add explicitly authorized Codex or Claude Code JSONL sources. - `longitudinal`: compare a validated report with the existing ledger. Default to inline, read-only output. Write a durable report under the target only when the user explicitly requests an artifact or historical tracking. Never discover user-home Sessions, read Memory bodies, or inspect another provider merely because its files are available. Use adjacent skills instead when their narrower owner is sufficient: - `codebase-audit` for code defects and architecture health; - `repo-agent-context-audit` for AGENTS, Skills, and Specs alone; - `skill-lifeguard` for one Skill's reliable contract; - `flowguard` for running a long task; - `review-gate` before landing an agent-generated diff. ## Step 1: Freeze The Evidence Boundary …

How to install
mdr add majiayu000/spellbook/review-agent-harness@sha256:c74ce96d46e52faaThe line at the top of this page pins the label git:20260812.ed81572, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
