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 | $0.01131 | $0.01131 |
| Opus 5 | $0.00566 | $0.00566 |
| Sonnet 5 | $0.00226 | $0.00226 |
| Haiku 4.5 | $0.00113 | $0.00113 |
Grade A, and why
go-agent-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 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.
How it starts
The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Guidance for AI Coding Agents
You are working on go-agent-skills, a repository of curated AI agent skills for Go development. These skills follow the Agent Skills standard format.
Project Context
This is NOT a Go application. It is a collection of Markdown instruction files (SKILL.md) that teach AI coding agents how to write idiomatic Go. The repo has no Go source code, no go.mod, and no build artifacts.
Repository Structure
skills/(category-name)/skill-name/SKILL.md
- Categories use parentheses:
(code-quality),(architecture), etc. - Each category has a
_category.jsonwith metadata. - Each skill is a directory containing at minimum a
SKILL.md. - Skills may also contain
references/for supplementary docs.
When modifying skills
- Read
docs/SKILL_GUIDELINES.mdfirst. It defines the quality standards. - Keep SKILL.md under 500 lines. Move detailed content to
references/. - YAML frontmatter is mandatory. Every SKILL.md must have
name,description,user-invocable,license,compatibility,allowed-tools,metadata.authorandmetadata.version.allowed-toolsis least-privilege: noEdit/Writefor review-only skills, and everyBash(...)entry scoped to one binary. - Name must match directory name.
go-code-review/SKILL.md→name: go-code-review. - Description must include trigger phrases AND negative triggers. Example:
Use when: "review this code", "check this PR" Do NOT use for: security audits (use go-security-audit) - Run validation before committing:
./scripts/validate.sh
When creating new skills
- Choose the correct category directory or create a new one.
- Create
skill-name/SKILL.mdwith proper frontmatter. - Add the skill to the README.md catalog table.
- If creating a new category, add
_category.json. - Run
./scripts/validate.shto verify format.
Code style for this repo
- Markdown: ATX-style headers (
#), fenced code blocks with language tags. - Shell scripts:
set -euo pipefail, shellcheck-clean. - JSON: 2-space indentation.
- No trailing whitespace. Final newline on all files.
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.

go-agent-skills AGENTS.md is an instructions file published in the GitHub repository eduardo-sl/go-agent-skills (71 stars, last pushed 22d ago), licensed MIT. It adds 1,131 tokens to every session, about $0.0057 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.
