Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00054 | $0.02216 |
| Opus 5.5 | $0.00022 | $0.00886 |
| Sonnet 5.5 | $0.00011 | $0.00443 |
| Haiku 4.5 | $0.00005 | $0.00222 |
Grade A, and why
using-agent-skills 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.
This is a copy
97% identical to using-agent-skills — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Using Agent Skills
Overview
Agent Skills is a collection of engineering workflow skills organized by development phase. Each skill encodes a specific process that senior engineers follow. This meta-skill helps you discover and apply the right skill for your current task.
Skill Discovery
When a task arrives, identify the development phase and apply the corresponding skill:

Core Operating Behaviors
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.

using-agent-skills is a skill published in the GitHub repository mamahoos/dot-files (5 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 2,216 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 97% identical to using-agent-skills, differing in 1 line, and is treated as a copy.
Other skills, from other repositories
golang-style
Go conventions specific to this author. Use before writing or editing any Go (.go) file.
gh-cli
GitHub CLI (gh) conventions and the inline PR review recipe. Use when working with GitHub repositories, PRs, issues, actions, gh api, or any GitHub operations from the command line.
gh-pr
This skill should be used when creating a GitHub pull request via gh pr create. Covers the gh CLI mechanics; PR title and body conventions come from the pr-style skill.
plan-loop
Plan work with the user in a PLAN.md, then implement it step by step, with /clear once the context fills up. Use before creating a plan, when the user mentions a PLAN.md, or when resuming work after /clear.
astro-dso-doc
Bootstraps a deep-sky object (DSO) astrophotography project from raw acquisition frames (own rig, not a smart telescope), AND generates a complete, polished HTML documentation page, a processing checklist, an AstroBin post JSON, a PixInsight process icon set (XPSM), and a ready-to-paste PixInsight project Description…
mbo-plan
Plan a new objective end-to-end in this repo's docs/mbo Management-By-Objective system — turn a GitHub issue or a gss draft-PR worktree into consistent design/spec/plan artifacts and track it in docs/mbo/index.md. Use this whenever the user wants to START planning or designing a new feature, skill, CLI, or service…
