A guide for creating and maintaining repositories that contain reusable agent skills. It covers their structure, validation, licensing, version matching, and release process.

Use it to build a skill repository, check plugin.json or SKILL.md files, configure MIT and CC-BY-SA-4.0 licensing, or release a new skill version.

It helps avoid invalid repository layouts, mismatched versions, licensing errors, and release mistakes.

skill-repo — Skill for Claude Code by netresearch

Install

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.

Any agent

npx skills add netresearch/skill-repo-skill --skill skill-repo

Clone the repo

git clone --depth 1 https://github.com/netresearch/skill-repo-skill

Made for: Claude Code.

Or install skill-repo, the plugin that ships this one along with the rest of its 1 skill.

Origin unknown No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

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	$0.00065	$0.01493
Opus 5	$0.00032	$0.00746
Sonnet 5	$0.00013	$0.00299
Haiku 4.5	$0.00006	$0.00149

Measured 5d ago against content hash 6e14c32ccaa7, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

skill-repo 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 5d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (scripts/bump-version.sh, scripts/check-version-parity.sh, scripts/fleet-release-common.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

39 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
