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 | $0.00097 | $0.02594 |
| Opus 5.5 | $0.00039 | $0.01038 |
| Sonnet 5.5 | $0.00019 | $0.00519 |
| Haiku 4.5 | $0.00010 | $0.00259 |
Grade A, and why
skill-authoring 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 — 304 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SKILL.md Authoring
This skill enacts the Endogenous-First axiom from MANIFESTO.md: skills are re-encodings of documented procedures and patterns from AGENTS.md, not independent inventions.
Skills are tactical-layer knowledge artifacts that encode how a task is done. They sit beneath agents (who encode who does a task) and above session behavior.
1. File Naming and Location
- Location:
.github/skills/<skill-name>/SKILL.md - Slug format: kebab-case, lowercase, e.g.
deep-research-sprint,pr-review-reply,session-management - One skill per domain — do not combine multiple domain procedures into a single skill file
To create a new skill, create the directory .github/skills/<skill-name>/ and add a SKILL.md file.
You can copy an existing SKILL.md as a starting point — for example:
cp .github/skills/source-caching/SKILL.md .github/skills/<skill-name>/SKILL.md
Then update the frontmatter and sections according to the conventions in this document.
2. YAML Frontmatter
Every skill file must open with YAML frontmatter:
---
name: <skill name in kebab-case>
description: |
<Clear description of what this skill encodes — ≥25 characters>
USE FOR: [bullet list of appropriate use cases]
DO NOT USE FOR: [bullet list of what this skill explicitly excludes]
argument-hint: "usage hint shown in chat input box"

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.

skill-authoring is a skill published in the GitHub repository EndogenAI/dogma (2 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 97 tokens to every session and 2,594 once invoked, about $0.0004 per session on Opus 5.5. 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.
