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 | $0.00845 | $0.00845 |
| Opus 5.5 | $0.00338 | $0.00338 |
| Sonnet 5.5 | $0.00169 | $0.00169 |
| Haiku 4.5 | $0.00085 | $0.00085 |
Grade A, and why
pm-skills AGENTS.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 2mo 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
pm-skills Repo Conventions
A public repo of product/R&D skills for Claude Code, Hermes Agent, Codex, and other skill-aware agents. Every directory at root is a stage of the R&D process (except .github/ and scripts/), and each stage contains related skills.

Skill Conventions
SKILL.mdmust have YAML frontmatter withnameanddescription.descriptionis a routing instruction for the model, not a human summary. Include trigger phrases.- Keep
SKILL.mdunder 500 lines. Move details toreferences/. - No README.md, CHANGELOG.md, or human-facing docs inside skill directories.
Frontmatter Format
---
name: my-skill
description: What this skill does and when to invoke it. Include trigger phrases.
---
Only name and description are required.
Writing Good Descriptions
The description field is the primary routing signal. When a user says "help me with X," the agent picks a skill based on description match.
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.
