Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/netresearch/skill-repo-skill --skill skill-repo- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads skill-repo automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.

SKILL.md Frontmatter
---
name: skill-name
description: "Use when <trigger conditions>"
---
Budgets (spec): name ≤64, no doubled/edge hyphen, matches its directory. description ≤1024, warn past 500 — a router, not documentation. Body ≤500 lines, warn at 300. compatibility ≤500, usually omit.
Flat discovery: references one level deep; SKILL.md names every references/*.md and every scripts/ executable; ## Contents past 100 lines. Rationale and trigger evals: skill-architecture. Audit: audit-skills.sh in the repository's top-level scripts/ (not shipped with the skill).
Manifests
Root plugin.json (Agent Plugins 1.0.0, closed field set) is the source of truth; sync-plugin-manifest.sh generates .claude-plugin/plugin.json plus Claude-only keys — agent-plugins-compat.
{
"$schema": "https://agent-plugins.org/schemas/1.0.0/plugin.schema.json",
"name": "skill-name",
"version": "1.0.0",
"license": "(MIT AND CC-BY-SA-4.0)",
"author": {"name": "Netresearch DTT GmbH", "url": "https://www.netresearch.de"}
}
composer.json
Name must match GitHub repo. Type ai-agent-skill. No version field (from git tags). No composer.lock.
{
"name": "netresearch/{repo-name}",
"type": "ai-agent-skill",
"license": "(MIT AND CC-BY-SA-4.0)",
"require": {"netresearch/composer-agent-skill-plugin": "*"},
"extra": {"ai-agent-skill": "skills/{name}/SKILL.md"}
}
Reusable Workflow Callers
Skill repos MUST delegate CI to skill-repo-skill reusable workflows:
# .github/workflows/validate.yml
uses: netresearch/skill-repo-skill/.github/workflows/validate.yml@main
Callers: validate.yml, release.yml (here); auto-merge-deps.yml (netresearch/.github). Auto-merge/pr-quality use pull_request_target. No inline Actions. Domain reusables: docs/ARCHITECTURE.md.
Releasing
Bump root plugin.json → sync → PR → merge → pull main → verify parity → signed tag → push → monitor Release. Tag only after bump PR merges. Multi-repo (>3) needs dry-run + approval; 0.x → 1.0.0 goes through STABILIZE rows, not retyped plans. Never edit installed paths — release-discipline.
Installation
Marketplace, release download, Composer, npm — commands and the npm files default in installation-methods.
Validation
scripts/validate-skill.sh (layout, manifests, budgets, flat discovery). Shell portability: authoring-ci-gotchas.
Named here so they are findable: bump-version.sh, check-version-parity.sh, sync-plugin-manifest.sh, roll-changelog.py, fleet-release-github.sh, migrate-licensing.sh, validate-evals.sh — each with --help.

FAQ
What does the skill-repo skill do?
Use when creating skill repositories, standardizing or validating skill repo structure, setting up composer/release workflows, configuring split licensing (MIT + CC-BY-SA-4.0), fixing plugin.json / SKILL.md validation or version-parity errors, writing, changing or validating evals/evals.json assertions and samples (graded as POSIX ERE by grep -qiE), or releasing a skill version (version bump, tagging).
How do I install skill-repo?
Run npx skills add https://github.com/netresearch/skill-repo-skill --skill skill-repo in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/skill-repo/ (personal) or .claude/skills/skill-repo/ (project).
Which AI agents can use skill-repo?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is skill-repo safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains skill-repo?
It is published by netresearch in netresearch/skill-repo-skill. It has 80 recorded installs.
Popular ai & agents skills
google-agents-cli-publish
google/agents-cli
This skill should be used when the user wants to "publish an agent", "publish my ADK agent", "register an agent with Gemini", "publish to Gemini" (formerly Gemini Enterprise), or needs guidance on the agents-cli publish gemini command. Also use when the user wants to "manage agents in Agent Registry", "list/update/delete registered agents", or "register an MCP server". Covers ADK vs A2A registration modes, programmatic and interactive usage, flag reference, auto-detection from deployment metadata, Agent Registry fleet management, and troubleshooting. Part of the agents-cli skills suite. Do NOT use for deployment (use google-agents-cli-deploy).
google-agents-cli-eval
google/agents-cli
This skill should be used when the user wants to "run an evaluation", "evaluate my agent", "evaluate my ADK agent", "write an eval dataset", "analyze eval failures", "compare eval results", "optimize agent", or needs guidance on the Gemini platform eval methodology and the Quality Flywheel. Covers eval metrics, dataset schema, LLM-as-judge scoring, and common failure causes. Applies to any agents-cli project, whatever framework the agent is written in. Do NOT use for agent API code patterns (ADK: use google-agents-cli-adk-code), deployment (use google-agents-cli-deploy), or project scaffolding (use google-agents-cli-scaffold).
skill-creator
anthropics/skills
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
codex-pet
prime-skills/runcomfy-agent-skills
Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
full-output-enforcement
leonxlnx/taste-skill
Overrides default LLM truncation behavior. Enforces complete code generation, bans placeholder patterns, and handles token-limit splits cleanly. Apply to any task requiring exhaustive, unabridged output.
executing-plans
obra/superpowers
Use when executing an implementation plan in the current session as the implementer yourself — your human partner chose inline execution, or no subagent tool is available
