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 | $0.00023 | $0.01801 |
| Opus 5 | $0.00012 | $0.00901 |
| Sonnet 5 | $0.00005 | $0.00360 |
| Haiku 4.5 | $0.00002 | $0.00180 |
Grade A, and why
hermes-agent-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 6d 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
86% identical to hermes-agent-skill-authoring — 32 lines 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.
How it starts
The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Authoring
Overview
There are two places a SKILL.md can live:
- User-local:
~/.agent/skills/<maybe-category>/<name>/SKILL.md— personal, not shared. Created viaskill_manage(action='create'). - In-repo (this skill is about this case): `/home/bb/
When to Use
- User asks you to add a skill "in this branch / repo / commit"
- You're committing a reusable workflow that should ship with
- You're editing an existing skill under `/home/bb/
Required Frontmatter
Source of truth: tools/skill_manager_tool.py::_validate_frontmatter. Hard requirements:
- Starts with
---as the first bytes (no leading blank line). - Closes with
\n---\nbefore the body. - Parses as a YAML mapping.
namefield present.descriptionfield present, ≤ 1024 chars (MAX_DESCRIPTION_LENGTH).- Non-empty body after the closing
---.
Peer-matched shape used by every skill under skills/software-development/:
---
name: my-skill-name # lowercase, hyphens, ≤64 chars (MAX_NAME_LENGTH)
description: Use when <trigger>. <one-line behavior>.
version: 1.0.0
author:
license: MIT
metadata:
hermes:
tags: [short, descriptive, tags]
related_skills: [other-skill, another-skill]
---
version / author / license / metadata are NOT enforced by the validator, but every peer has them — omit and your skill sticks out.
Size Limits
- Description: ≤ 1024 chars (enforced).
- Full SKILL.md: ≤ 100,000 chars (enforced as
MAX_SKILL_CONTENT_CHARS, ~36k tokens). - Peer skills in
software-development/sit at 8-14k chars. Aim for that range. If you're pushing past 20k, split intoreferences/*.mdand reference them from SKILL.md.
Peer-Matched Structure
Every in-repo skill follows roughly:
# <Title>
## Overview
One or two paragraphs: what and why.
## When to Use
- Bulleted triggers
- "Don't use for:" counter-triggers
## <Topic sections specific to the skill>
- Quick-reference tables are common
- Code blocks with exact commands
- the agent-specific recipes (tests via scripts/run_tests.sh, ui-tui paths, etc.)
## Common Pitfalls
Numbered list of mistakes and their fixes.
## Verification Checklist
- [ ] Checkbox list of post-action verifications
## One-Shot Recipes (optional)
Named scenarios → concrete command sequences.
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.

hermes-agent-skill-authoring is a skill published in the GitHub repository sairam0424/MindForge (0 stars, last pushed today), licensed MIT. It adds 23 tokens to every session and 1,801 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings.
