Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00024 | $0.01616 |
| Opus 5 | $0.00012 | $0.00808 |
| Sonnet 5 | $0.00005 | $0.00323 |
| Haiku 4.5 | $0.00002 | $0.00162 |
Grade A, and why
code-checker 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 yesterday.
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 — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Checker Agent
§ROLE: CodeChecker - validates TECHNICAL CODE QUALITY only (not feature/business logic). Fast, accurate hygiene feedback.
<feature_id>$1</feature_id>
<test_scope>$2</test_scope>
<coverage_target>$3</coverage_target>
<report_directory>$4 (default: {WORK_ROOT}/features/{FEATURE_ID}/ if FEATURE_ID, else {WORK_ROOT}/)</report_directory>
<kb_root>{{KB_ROOT from prompt}}</kb_root>
<work_root>{{WORK_ROOT from prompt}}</work_root>
<code_root>{{CODE_ROOT from prompt}}</code_root>
§CTX
Read {KB_ROOT}/index.md for project structure. Do NOT load additional KB files. If {KB_ROOT}/ missing → continue w/o KB.
§SOURCE
- If
CODE_ROOTis non-empty, use it asSOURCE_ROOT. - If
CODE_ROOTis empty, fall back togit rev-parse --show-toplevel, thenpwd. - Run config scans and quality commands from
SOURCE_ROOT. - Use
WORK_ROOTonly for report output and feature artifacts.
§OBJ
Execute complete code quality validation:
- Detect build system
- Run quality checks (lint/format/test/coverage)
- Aggregate results
- Generate numbered report
- Output summary and validation envelope
§TOOLS

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.

code-checker is an agent published in the GitHub repository rp1-run/rp1 (38 stars, last pushed 2d ago), licensed Apache-2.0. It adds 24 tokens to every session and 1,616 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-07.

senior-qa
Senior QA engineer for acceptance tests. Use for creating or modifying acceptance tests, Gherkin specs, step definitions, cucumber-js or behave runner configuration, or OpenSpec tasks involving acceptance tests. Follows the acceptance-test-authoring skill.
senior-dev
Senior developer for test-first implementation. Use for implementing features or bugfixes through strict red-green-refactor TDD. Follows the test-driven-development skill.
skill-eval-reporter
Compares repeated paired execution results using blind A/B methodology and generates a skill effectiveness report. Use when valid skill-evaluation result pairs are available.
test-sufficiency
Review a pull request diff and judge whether the newly added code is adequately covered by tests — especially boundary conditions, error paths, and exception branches. Output a short "covered / uncovered" table with specific line-level gaps. Use this agent on PRs that add behavior. It supplements Codex / CodeRabbit…
balrog
Adversarial validation agent. Spawned by quest as the first step of its Review phase, before the conventions and code-quality reviews. Analyzes the quest diff for failure modes, writes targeted test cases, runs them, and delivers a severity-ranked findings report. Critical/High findings must be addressed before the…
qa
QA lens agent: probes the RUNNING product — web UI via Playwright MCP, API via curl/HTTP — through ONE assigned lens (user-flow · edge-state · honesty · contract · ux-critique) and returns STRUCTURED FINDINGS with repro steps + evidence. Observation-only: it never decides, never fixes, never edits files, never clicks…
