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 | $0.00763 | $0.00763 |
| Opus 5.5 | $0.00305 | $0.00305 |
| Sonnet 5.5 | $0.00153 | $0.00153 |
| Haiku 4.5 | $0.00076 | $0.00076 |
Grade A, and why
hone-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 1mo 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hone Skills & Eval Suite
This repository stores AI skill files and evaluation suites for code-quality practices derived from timeless software engineering principles.
Repository scope
skills/contains skill definitions.evals/contains evaluation suites and fixtures.README.mdis the primary overview and usage guide for the repository.
Naming convention
- Every skill identifier/name must be prefixed with
hone:. - Avoid creating new skill names that do not start with
hone:.
Installation
- Install skills with
npx skills add ckorhonen/hone-skills. - Document install examples using
npx skills add ckorhonen/hone-skills.
Marketing site (site/)
site/contains the static marketing website.- The site showcases all hone: skills with descriptions, example prompts, sample output, and suggested schedules.
Site sync rules
- Adding a skill: Add a skill card to the appropriate category section
in
site/index.html. Include the skill name, one-line description, and an example prompt. Add it to the relevant schedule card in the Schedules section. Update the skill count in the hero lede and page title. - Removing a skill: Remove the skill card, its schedule entry, and adjust counts accordingly.
- Modifying a skill: After changing a skill's description, trigger
conditions, or output format, review
site/index.htmlfor accuracy.
Workflow notes
- Keep additions narrowly scoped.
- Keep files small and reviewable.
- Co-locate related skill and eval assets in their feature directories.
- Update
README.mdwhenever repository structure or workflows change. - Do not land changes that make
README.mdmaterially inaccurate. - Do not land changes to skills without checking
site/index.htmlfor accuracy.
Source-backed checks
Use Bun and the tracked lockfile. Installation runs the package's prepare hook to configure simple-git-hooks; account for that local Git configuration effect before setup. bun run evals:check executes scripts/validate-evals.mjs and checks evaluation structure, while bun run lint:md runs Markdownlint. lint:md:fix rewrites files. There is no application build or unit-test script.
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.
