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 | $0.01356 | $0.01356 |
| Opus 5 | $0.00678 | $0.00678 |
| Sonnet 5 | $0.00271 | $0.00271 |
| Haiku 4.5 | $0.00136 | $0.00136 |
Grade A, and why
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 3d 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Skill Authoring Conventions
Rules specific to writing skills for this repository. For global agent behavior, see the
global-rulesskill. These conventions follow thewriting-great-skillsframework: a skill exists to make the agent take the same process every run. Predictability is the goal every rule below serves.
Meta-Rule: Draft Before Writing
Never write a skill file without explicit user confirmation.
- Propose a plan (name, location, flags, structure)
- Wait for user to say "yes" or request changes
- Only then write the
SKILL.mdfile
This applies to every skill, no exceptions.
Meta-Rule: Update README
After writing a new skill, update README.md before committing.
- Add the skill to the quickstart invocation list.
- Add a failure mode entry in
## Why These Skills Existif applicable. - Add a row to the
## Referencetable with name, link, description, and flags.
Do not commit the skill without the README update.
Meta-Rule: Self-Check Before Committing
Before committing any skill addition or update, verify every rule below by reading the files. There is no validator script; you are the check.
For every skill you touched:
- name, present in frontmatter, kebab-case (
^[a-z0-9]+(-[a-z0-9]+)*$), 64 chars or fewer, and exactly matches the skill's directory name. - description, present and 1024 characters or fewer.
- SKILL.md length, 100 lines or fewer.
- README coverage, the skill appears in the
README.mdquickstart list (as/<name>) and has a row in the## Referencetable linking./skills/<name>/SKILL.md. - Markdown links resolve, every real
.mdpath linked or backticked inSKILL.mdpoints to a file that exists. Ignore template paths containing<...>placeholders.
Fix every failure before committing. Do not commit until all five pass.
Project Structure
- Skills live in
skills/<name>/SKILL.md(project-level) - Never use
.agents/skills/for this repo - Each skill is a directory containing
SKILL.mdat minimum - Optional:
REFERENCE.md,references/,assets/
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.

skills AGENTS.md is an instructions file published in the GitHub repository prathamdby/skills (4 stars, last pushed 8d ago), licensed MIT. It adds 1,356 tokens to every session, about $0.0068 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 2026-08-31.
