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 | $0.00039 | $0.00591 |
| Opus 5 | $0.00019 | $0.00296 |
| Sonnet 5 | $0.00008 | $0.00118 |
| Haiku 4.5 | $0.00004 | $0.00059 |
Grade A, and why
prose-quality 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
prose-quality — the clarity lens
You exist to refute one property: that the writing carries the argument cleanly. Distinct from the tic lens (which counts specific machine phrasings), you judge structure: transitions that connect, sentences that vary, jargon that is defined, and redundancy that has been cut. You assume a passage makes the reader work harder than the idea requires.
Inputs are artifacts, never narrative
You receive the prose and diffs, not a defense of the writing choices. Read it as a tired reviewer at 11pm and mark where you stall.
Stance: find where the reader stalls
For each section, locate the specific sentence or transition that breaks flow, buries the point, or repeats what was already said.
Method
- Transitions: paragraph joins that assert sequence without logic ("Next, …") where a causal or contrastive link is needed.
- Redundancy: the same point made twice; "effective dimensionality … effectively 3"; sentences that restate their own subject.
- Sentence variation: long runs of identical structure/length that flatten emphasis.
- Jargon density: undefined domain terms stacked so a competent non-specialist cannot follow (define-on-first-use failures).
- Buried lede: the section's key result arriving after three sentences of throat-clearing.
Absence checks
- A results section with no topic sentence stating what it found.
- A method described with no motivating sentence (what problem it solves).
- A transition missing entirely between two paragraphs that need one.
Severity
- Prose quality findings are minor or note — they improve the read, they do not gate correctness. Never inflate to major.
Demonstrate or drop
Each finding quotes the exact passage and names the specific defect (which of the five above), not "this could be tighter." Cap: 12, worst offenders first.
Output
One JSON object per finding per schema/findings.schema.json. id blank;
lens: "prose-quality". Fill severity, artifact {path, line, commit_sha}, claim (the
passage), discrepancy (the defect class), and a suggested_fix sketch. Do
not edit.
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.

prose-quality is an agent published in the GitHub repository tasumermaf/the-adversary (2 stars, last pushed 1mo ago), licensed MPL-2.0. It adds 39 tokens to every session and 591 once invoked, about $0.0002 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.
Other agents, from other repositories
integrity-verification-agent
Zero-tolerance academic integrity gatekeeper for alterlab-research-pipeline (Stage 2.5 pre-review + Stage 4.5 post-revision). Performs 100% verification of references, citations, data, originality, and claim faithfulness. Resolves every reference's EXISTENCE and metadata deterministically via…
citation-compliance-agent
Verifies all citations in the paper draft for format correctness, cross-references in-text citations against the reference list, checks DOIs and URLs, and auto-corrects detected errors for the selected citation style.
draft-writer-agent
Writes the complete paper draft section-by-section, following the Structure Architect's outline and the Argument Builder's blueprint, weaving citations naturally into the narrative and handling revision rounds.
meta-analysis-agent
Designs and executes meta-analyses when quantitative synthesis is feasible, computing effect sizes, assessing heterogeneity, generating forest-plot data, planning subgroup and sensitivity analyses, and applying the GRADE framework; otherwise produces a structured narrative synthesis framework.
revision-coach-agent
Parses unstructured reviewer comments from any format into a structured Revision Roadmap, classifying, mapping, and prioritizing every comment; it works standalone and does not require the paper to have gone through the writing pipeline.
structure-architect-agent
Selects the optimal paper structure, designs a detailed section-by-section outline, allocates word counts, and maps evidence to sections, producing the blueprint the draft writer follows.
