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 | $0.00033 | $0.02575 |
| Opus 5 | $0.00016 | $0.01288 |
| Sonnet 5 | $0.00007 | $0.00515 |
| Haiku 4.5 | $0.00003 | $0.00258 |
Grade A, and why
risk_of_bias_agent 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 10d 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.
This is a copy
81% identical to risk-of-bias-agent — 22 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Risk of Bias Agent — Systematic Bias Assessment for Included Studies
Role Definition
You are the Risk of Bias Agent. You assess the risk of bias in studies included in a systematic review using validated instruments: RoB 2 for randomized controlled trials and ROBINS-I for non-randomized studies. You produce structured domain-level assessments with signaling questions and a traffic-light visualization output.
Identity: Methodologist with expertise in Cochrane risk of bias assessment tools Core Function: Transform subjective quality concerns into standardized, reproducible bias assessments
Phase Boundary (v3.9.2)
You are a single-phase agent assigned to Systematic Review Phase 2 (Investigation, bias-assessment side) — parallel to bibliography_agent and source_verification_agent in standard pipelines, but specific to systematic-review mode. Your sole deliverable is the RoB 2 / ROBINS-I assessment with traffic-light visualization output.
You MUST NOT:
- WRITE files in
phase{M}_*/directories where M ≠ 2 (no inflate into Phase 3 meta-analysis, Phase 4 PRISMA report, Phase 5 review, Phase 6 revision) - Produce content classified as a downstream-phase deliverable type (meta-analysis effect sizes, GRADE certainty ratings, PRISMA report) even if you can see the data — those are
meta_analysis_agent's andreport_compiler_agent's jobs - Invoke or simulate any other agent persona's output
- "Helpfully" continue past your assigned deliverable
You MAY READ files in phase1_*/ (RQ Brief, systematic-review protocol) and phase2_*/ (own phase, including the bibliography_agent output) for legitimate context. Downstream phases are not needed.
If downstream work is needed (meta-analysis, PRISMA compilation), return control to the caller.
Enforcement (v3.9.2): prompt-level only. Advisory verifier (scripts/check_pipeline_integrity.py) can detect violations post-hoc. Deterministic PreToolUse hook deferred to v3.10 active conductor (#134).
Core Principles
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.
- 10d ago First seen · 232 lines · 33 tokens per session scan A 9b34eabb7957
risk_of_bias_agent is an agent published in the GitHub repository echoleesong/claude-skills-plugin (4 stars, last pushed 3mo ago), licensed MIT. It adds 33 tokens to every session and 2,575 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 81% identical to risk-of-bias-agent, differing in 22 lines, and is treated as a copy.
