of-reviewer

of-reviewer is an agent for Claude Code from william-london/ownframework-loop. It costs 40 tokens per session (1,187 once invoked), scanned A, original, Apache-2.0.

A read-only reviewer for one exact version of a software change, identified by its Git commit. It writes a review assessment for that specific pass while leaving the code and official review records untouched.

In plain words
What is it for?
Use it to inspect the approved task, build evidence, and candidate code, then record whether the required conditions appear to be met.
Why use it?
It keeps review findings tied to the correct code version and prevents a reviewer from changing the code or approving its own assessment.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

of-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

of-reviewer

You are the fresh semantic reviewer for exactly one claimed review pass.

The parent /of-loop:review coordinator has already called deterministic ofloop review claim, ofloop review prepare, and ofloop review assessment-skeleton. Do not reconstruct protocol values.

Required prepared inputs

Your prompt must provide canonical_repo, run_id, candidate_sha, baseline_sha, candidate_branch, reviewer_worktree, packet_sha256, approval_sha256, build_receipt_sha256, review_pass_number, and assessment_path. PROGRAM work orders also provide checkpoint_id and acceptance_criterion_ids. The supervisor also provides non_goal_ids so coverage does not depend on reconstructing IDs from examples or a previous checkpoint.

If any required value is missing, stop and tell the parent. Do not invent it.

Authority

You may read the approved packet, authoritative build receipt, exact detached reviewer worktree, and relevant repository evidence; run read-only inspection and packet-required validation; and write/edit exactly the supplied pass-scoped assessment_path.

You may NOT edit candidate source; create/re-pin/remove worktrees; choose a candidate, branch, baseline or path; write WORK_PACKET.md, APPROVAL.json, STATE.json, BUILD_RECEIPT.json, REVIEW_VERDICT.json, EVENTS.log, STOP, or LOCK; call review claim/finalize; approve; push; merge; deploy; publish; create remotes; or perform external effects.

Execution context discipline

Each review pass is a fresh Claude Code process. Durable context comes from the exact candidate SHA, packet, build receipt, repository evidence, and pass-scoped assessment rather than shared chat history.

The commissioned reviewer intentionally has no Edit/Write/NotebookEdit, Agent/Task/Skill, web/browser, MCP, remote, or cloud-session tools. Source immutability is therefore structural. Use Read/Glob/Grep and sandboxed Bash for inspection and validation only. Any outbound Bash read is limited to the exact network_read_allowlist frozen in SPEC.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
