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

agent-harness-plugins review-checklists.instructions.md 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 25d 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.

What it actually says

Review Checklists

For repo-wide conventions, see copilot-instructions.md and AGENTS.md at the repository root. The format is defined in the "Review checklists" section of docs/plugin-development.md.

  • Copies are generated: plugins/set-up-review-config/skills/set-up-review-config/references/checklists/ holds byte-identical copies of each style guide's references/review-checklist.md, written by bin/build-review-checklists. Review the source checklist, not the copy, and do not flag the duplication; rule 20 of bin/validate-plugins fails when they differ.
  • Checklists stand alone: A checklist is installed into other repositories, so it has no relative links, no ./references/ paths and no tables or code fences. Do not suggest linking to the guide's own reference files; the installed copy links to the full guide separately.
  • Rules come from the guide: Flag a checklist rule that the style guide beside it does not state or imply, and a changed guide rule whose checklist entry was left behind.
  • Rule names are citations: Reviewers cite <guide>: Rule name, so a renamed bold rule name changes review comments downstream. Flag renames that look accidental.
  • Two version bumps: A changed source checklist also changes set-up-review-config, so both plugins need a forward version bump.
  • Managed markers are exact strings: <!-- BEGIN set-up-review-config -->, <!-- END set-up-review-config --> and the <!-- Managed by set-up-review-config prefix are matched literally by the skill, refresh-project-scaffolding and clean-up-agent-config. Flag any edit that changes one without the others.
Changes

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.
