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 | $0.00848 | $0.00848 |
| Opus 5 | $0.00424 | $0.00424 |
| Sonnet 5 | $0.00170 | $0.00170 |
| Haiku 4.5 | $0.00085 | $0.00085 |
Grade A, and why
writing-with-agents CLAUDE.md 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.

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing With Agents — Project Configuration
This file governs Claude's behavior when working on the writing-with-agents repository.
Skill Authorship Standards
Skills follow the Agent Skills specification. This section covers project-specific conventions.
The Description Trap
Critical: Skill descriptions must be TRIGGER-ONLY. Never summarize the workflow or process.
BAD — Process in description:
description: Use for brainstorming. First generate raw material across dimensions,
then present to user for seeding, then overproduce 3-5x.
GOOD — Trigger-only:
description: Use when brainstorming ideas, generating raw material, or starting
the creative phase of a writing project.
Format: Use when [specific triggering conditions]

Progressive Disclosure Architecture
Tier 1 — SKILL.md (~80-100 lines)
- Role definition and collaborative model (who leads, who supports)
- When-to-use guidance (triggers)
- Core workflow (5 steps)
- Constraints (MUST DO / MUST NOT DO)
- Routing table to references
Tier 2 — Reference Files (100-600 lines each)
- Deep procedural content
- Templates and output formats
- Examples and anti-patterns
- Loaded only when context requires

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.

writing-with-agents CLAUDE.md is an instructions file published in the GitHub repository Jeffallan/writing-with-agents (30 stars, last pushed 2mo ago), licensed MIT. It adds 848 tokens to every session, about $0.0042 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 2026-08-30.
