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 | $0.00178 | $0.02044 |
| Opus 5 | $0.00089 | $0.01022 |
| Sonnet 5 | $0.00036 | $0.00409 |
| Haiku 4.5 | $0.00018 | $0.00204 |
Grade A, and why
draft-prose 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.
How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
draft-prose
Purpose
Turn an approved, validated outline into continuous prose. This skill is a faithful renderer: it dresses an already-sound skeleton in sentences a reader can follow, and it treats the resulting draft as revisable raw material, not a finished document. Its defining discipline is that it adds nothing the outline does not already assert.
When to use
- A validated
argument-blueprintexists and the user wants it written up. - The request is "draft the prose", "write this from the plan", "render the outline into paragraphs".
When NOT to use
- No validated outline yet, or the structure is still in flux -> build-argument.
- A draft already exists and needs fault-finding -> diagnose-draft.
- A draft exists and needs structural or sentence-level repair -> revise-structure / revise-prose.
Inputs
argument-blueprintcontract (validated outline: governing question, controlling idea, grouped/ordered claims, opening plan, layout map).reader-framecontract (prior knowledge, standing question, expertise level, mastered vocabulary, blind spots).
If the blueprint is present but unvalidated, stop and route back to build-argument -- do not draft on an unchecked skeleton.
Workflow
- Read the reader-frame; fix the mastered-vocabulary set and the assumed prior knowledge that govern word choice.
- Walk the layout map section by section. For each section, render its parent claim as a topic sentence and its children as the supporting sentences, keeping the ordering the blueprint fixed.
- Write the opening from the blueprint's opening plan (context, tension, question, answer) -- assert only what the reader already accepts in the context; do not argue the premises.
- Maintain a node-to-prose map: every outline node points to the prose span that renders it, so a later pass can trace any sentence back to its claim.
- Keep flow honest: hold each topic string in or near subject position, put given information before new, mark only the coherence relations the reader would not otherwise infer, and keep wording concrete and picturable.
- Run the prose over the analyzer indicators and revise obvious clarity traps in place before handing off.
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.

draft-prose is a skill published in the GitHub repository OC-NeuralSense/reader-first-writing-skills (1 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 178 tokens to every session and 2,044 once invoked, about $0.0009 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.
