A review workflow for pull requests that add tasks to SkillsBench, a benchmark for testing AI coding agents. It checks the task rules, runs comparisons across several agents, and reviews their work traces.

Reviewing SkillsBench task pull requests, checking policy compliance, benchmarking Claude and Codex with and without skills, auditing trajectories, and producing a report plus submission bundle.

It removes the need to manually classify benchmark tasks, apply different rule sets, compare agent results, and inspect whether agents cheated or used skills correctly.

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.

Model	Per session	Once invoked
Fable 5	$0.00141	$0.04585
Opus 5	$0.00071	$0.02292
Sonnet 5	$0.00028	$0.00917

Security

Grade B, and why

task-review scanned grade B with 2 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 2d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/fetch_pr.sh, scripts/package_traj.sh, scripts/parse_results.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

1. The user's own configs: `cat ~/.codex/config.toml` (often pins a Codex model + reasoning effort), `~/.claude/settings.json` for Claude.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

SkillsBench Task Review

Repo context. This skill lives in the benchflow repo but reviews PRs against benchflow-ai/skillsbench. Unqualified references below — CONTRIBUTING.md, MAINTAINER.md, docs/*.md, tasks/<task-id>/ — mean files in skillsbench. scripts/fetch_pr.sh defaults to that repo; override with SKILLSBENCH_REPO. For auditing already-published run trajectories, use benchflow-experiment-review instead.

End-to-end review of a SkillsBench task PR. Two artifacts are produced: a human-readable .txt report, and a pr<N>.zip bundle that mirrors the format reviewers post on PRs (see PR #560 comment for the reference structure).

Workflow

1. fetch       → pull PR files into a workspace (no git checkout)
2. route       → classify task track; pick the track-specific rubric
3. policy      → static checks against rubric (no execution)
4. benchmark   → 5 configs: oracle + claude×{skills,no} + codex×{skills,no}
5. audit       → read trajectories: skill use, cheating, root cause of failures
6. report      → fill report-template.txt and bundle pr<N>.zip

Each step is described below. Run them in order — never skip benchmark to write a verdict, never skip audit to interpret results.

Step 1 — Fetch the PR

scripts/fetch_pr.sh <pr_number> <workspace>
# → echoes the task dir path; writes <workspace>/pr-<N>.meta.json with PR metadata.

Use gh API + raw download. Do not gh pr checkout or git pull — keep the local clone clean. For a local-path review, skip this step and pass the task directory directly to step 3.

Step 2 — Route to a track

A SkillsBench task belongs to one of three tracks. The track determines what "verifiable" means and which policy items apply. Always classify before running policy checks — applying the wrong rubric is the most common reason a review goes sideways.

What ships with it

12 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

task-review is a skill published in the GitHub repository benchflow-ai/benchflow (335 stars, last pushed 3d ago), licensed Apache-2.0. It adds 141 tokens to every session and 4,585 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). It is 95% identical to task-review, differing in 7 lines, and is treated as a copy.
