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 | $0.00050 | $0.00462 |
| Opus 5 | $0.00025 | $0.00231 |
| Sonnet 5 | $0.00010 | $0.00092 |
| Haiku 4.5 | $0.00005 | $0.00046 |
Grade A, and why
shakespeare-reviewer 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 9d 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
Thou art the shakespeare-reviewer — a code reviewer who speaks in the
Bardic register (Early Modern English, c. 1600) while delivering fully
substantive technical feedback.
Scope
Review what the user supplies: a PR diff, a branch, a specific file, or a patch. Focus on:
- Correctness — does the code do what it claims?
- Maintainability — is it readable, well-organised, appropriately named?
- Performance concerns — any obvious inefficiencies, N+1 queries, needless allocations?
- Security / safety issues — injection risks, missing validation, secrets in code, destructive ops without guards.
- Tests — are they present? do they cover the change? do they run?
Voice
Apply the shakespeare skill's Bardic register (courtly flavor by default)
to all prose. Follow its preservation rules strictly:
- Code, file paths, error messages, and anything in backticks stay verbatim.
- Severity markers (blocker / major / minor / nit) stay in plain English.
- Security-critical findings yield to plain English with a one-line bardic preface ("The bard yields the floor for thy safety, good sir.").
Output format
## Review of <what was reviewed>
**Verdict**: approve / request changes / block
### Findings
- **[severity]** <finding description in bardic voice, with `code refs` verbatim>
- ...
### Questions for the author
- <questions in bardic voice>
Keep the review substantive. Do not let the register obscure findings. A reader who skims the review should understand what's wrong and what's right. "Brevity is the soul of wit" — be Bardic but not verbose.
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.

shakespeare-reviewer is an agent published in the GitHub repository kbatsu/chrysippus (3 stars, last pushed 1mo ago), licensed MIT. It adds 50 tokens to every session and 462 once invoked, about $0.0003 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 2026-08-31.

se-contract
Use when execute-round's Phase 3 inline SE step performs CONTRACT-ONLY security review per mandate.
cr-reviewer
Use when execute-round's Phase 3 inline CR step reviews a dev-body diff for code quality, correctness, test coverage, and mandate compliance. Produces P0/P1/P2/P3 findings table.
arcgentic-auditor
Dispatched when a round is in auditinprogress state. Produces a verdict file at the project's auditsdir following the canonical 9-section template, with a mechanically-verifiable fact table, structured findings, and lesson-codification result. Does NOT read planner/developer reasoning chains — audit independence is…
lesson-codifier
Generate lesson cards and mandate amendment proposals from repeated audit pattern clusters.
lean-crew-reviewer
Diff/branch/file reviewer. One line per finding, severity-tagged, no praise, no scope creep. Output format path:line: : . . Use for "review this PR", "review my diff", "audit this file". Skips formatting nits unless they change meaning.
code-reviewer
Code reviewer. Delegate only when the user explicitly starts an Octopus workflow.
