skill-improver

Improve skills and workflows by analyzing run artifacts and execution logs (events.jsonl/state.json) under runs/ (or OpenSpec changes/). Use when you want to iterate on skills based on real runs: find failure modes, bottlenecks, unclear prompts, missing I/O contracts, and propose concrete edits.

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/heyvhuang/ship-faster --skill skill-improver
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads skill-improver automatically when relevant.

  3. 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 Improver

Retrospect and improve Skills/Workflows based on real execution artifacts, making the skill chain more stable with use.

Input (pass path only)

  • run_dir: runs/<workflow>/active/<run_id>/ (or openspec/changes/<change-id>/)

Output

  • improvements.md: Improvement suggestions (can be directly converted to change tasks)
  • Optional: Minimal patch to relevant SKILL.md (only change what's necessary)

Process

  1. Read logs/state.json and logs/events.jsonl, extract:
    • Failure points (error types, frequency, missing context)
    • Time bottlenecks (repetitive steps, ineffective searches, excessive context)
    • Manual confirmation points (whether too early/too late/missing)
  2. Check artifact contracts:
    • Whether each step has persisted output
    • Whether only paths are passed instead of content
    • Whether there are inconsistent naming/paths
  3. Output improvement suggestions (sorted by benefit):
    • Prompt/trigger word optimization
    • I/O contract completion (add required fields, fix artifact file names)
    • Error handling and rejection strategies
    • Suggest new deterministic scripts (only when necessary)

Output Template (recommended)

  • Overview: Core issues from this run
  • Top Issues (high → low): Each includes "symptom/root cause/fix suggestion/related skill/suggested change point"
  • Suggested Minimal Change List: Listed by file

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).

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.
