Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is atheurer/agentic-perf's own configuration. It tells Claude Code and Codex how to work on agentic-perf itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentic-perf configures →

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

agentic-perf-pr-cycle 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 today.

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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agentic-perf PR cycle

Use this skill to work through an existing pull request from initial review to final CI checks. For the one-at-a-time backlog workflow, read references/backlog-pr-cycle.md. For a new implementation, use the issue-first development workflow in agentic-perf-orchestration, then return here for the PR review and landing steps.

Repository guidance is authoritative for current commands and policy. Read AGENTS.md, CONTRIBUTING.md, docs/reviewing.md, and the relevant audit or testing docs for the paths under review. Do not copy mutable project details into this skill when a repository document already owns them.

Review, fix, and revalidate

  1. Verify the clean base checkout, PR base and head SHAs, author, changed files, commits, and check state. Record the expected remote head. Use an isolated worktree for source review; do not bring unrelated checkout changes into it.
  2. If the PR is based on stale main, bring the exact PR head onto the current origin/main in a fresh worktree. Resolve conflicts deliberately and inspect the complete resulting diff. Stop before pushing if the remote PR head has changed.
  3. Review the full diff independently from its implementation. Trace changed contracts through their producers, consumers, schemas, prompts, and tests. Apply docs/reviewing.md and the relevant audit policies.
  4. Classify each finding as PR-introduced or review-discovered follow-up. Fix material PR-introduced correctness, security, or behavior findings before push. Track pre-existing follow-ups separately; create a focused issue when that is appropriate for the workflow and link it to the PR. Do not describe a pre-existing defect as a regression.
  5. After every implementation or generated-file change, format the changed files before testing and inspect the complete diff. Repeat the independent review and every affected validation step after review-driven fixes.

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.
