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 | $0.00022 | $0.03576 |
| Opus 5 | $0.00011 | $0.01788 |
| Sonnet 5 | $0.00004 | $0.00715 |
| Haiku 4.5 | $0.00002 | $0.00358 |
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 7d 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
100% identical to hermes-agent-skill-authoring — 2 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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Authoring Hermes-Agent Skills (in-repo)
Overview
There are two places a SKILL.md can live:
- User-local:
~/.hermes/skills/<maybe-category>/<name>/SKILL.md— personal, not shared. Created viaskill_manage(action='create'). - In-repo (this skill is about this case):
skills/<category>/<name>/SKILL.mdoroptional-skills/<category>/<name>/SKILL.mdinside the hermes-agent repo — committed, shipped with the package. Usewrite_file+git add.skill_manage(action='create')does NOT target this tree.
In-repo skills must meet the repo's hardline authoring standards (see AGENTS.md, "Skill authoring standards (HARDLINE)" — that section is the source of truth; this skill is the operational walkthrough). Reviewers reject PRs that violate them, so meeting them up front is cheaper than a salvage pass later.
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 hermes-agent
- You're editing an existing skill under
skills/oroptional-skills/(usepatchfor small edits,write_filefor rewrites;skill_managestill works for patch on in-repo skills, but not forcreate) - Don't use for: personal skills in
~/.hermes/skills/(just useskill_manage)
Decide the Tier First: Bundled vs Optional
- Bundled (
skills/<category>/) — daily-driver behavior, broadly useful across many user types, low footprint. Hard bar: you can say "a user will load this in 5+ sessions per month" with a straight face. - Optional (
optional-skills/<category>/) — niche, vertical-specific (blockchain, gaming, finance, one app), recurring-job/task skills, or anything heavy. Installed viahermes skills install official/<category>/<skill>.
When in doubt, optional. Promoting later is easy; demoting is churn. "Would be useful to anyone who ever needs this" is an optional-tier argument, not a bundled one.
Pick the category by what the tool IS, not what it feels like (an AI-agent CLI goes in autonomous-ai-agents/ even if it "feels productivity"). Confirm existing categories with search_files(pattern='*', target='files', path='skills') and don't invent new top-level categories casually.
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.
