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 | $0.00027 | $0.02721 |
| Opus 5 | $0.00014 | $0.01360 |
| Sonnet 5 | $0.00005 | $0.00544 |
| Haiku 4.5 | $0.00003 | $0.00272 |
Grade A, and why
critique 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Critique
Stress-test an outline or draft before it moves forward. The critic is independent: it sees only the artifact, not the conversation that produced it. That independence is deliberate; the critic should not know why the author made the choices they did, only what they chose.
When to use
- The user has an outline at
<drafts_dir>/<slug>/outline.mdand wants oppositional review before drafting. - The user has a draft at
<posts_dir>/<slug>/index.mdand wants it reviewed against its outline before revising.
Do NOT use for:
- Producing a new outline from a topic → use
/interrogate. - Writing the draft itself → use
/author. - Line-level edits on a draft without adversarial review → use
/revise.
Preconditions
Run these as a silent preflight. Do not narrate them to the user unless a check fails; a passing preflight should be invisible.
1. .prospero/config.toml must exist
If .prospero/config.toml does NOT exist in the current working directory, invoke the prospero:init skill and follow it to completion. When init returns, resume at step 2 below. Do not proceed to critique with an unconfigured project.
2. .prospero/voice.md and .prospero/audience.md must be filled in
For each of .prospero/voice.md and .prospero/audience.md, compute byte-for-byte equality against the plugin's corresponding template at <plugin-root>/templates/voice.md and <plugin-root>/templates/audience.md. Use the plugin-root resolution procedure defined in the init skill's "Resolving the plugin's templates directory" section. Do not abbreviate its failure handling: zero matches → ask the user; multiple matches → ask the user; match found but voice.md or audience.md missing → halt with the resolved path.
- If either user file is Missing → halt with: "
.prospero/<file>is missing. Run/initto restore it, then fill it in before/critique." - If either user file is byte-for-byte equal to its template → halt with: "
.prospero/<file>is the unmodified scaffold. Fill it in before running/critique; this is the one thing Prospero cannot write for you." - Otherwise → the file is user content. Proceed.
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.

critique is a skill published in the GitHub repository bguthrie/prospero (6 stars, last pushed 4mo ago), licensed MIT. It adds 27 tokens to every session and 2,721 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 2026-08-31.
