Create, synthesize, and iteratively improve agent skills following the Agent Skills specification. Use when asked to "create a skill", "write a skill", "synthesize sources into a skill", "improve a skill from positive/negative examples", "update a skill", or "maintain skill docs and registration". Handles source capture, precision passes, authoring, registration, and validation.

Source Adaptation

Use this when turning an upstream prompt, workflow, rubric, benchmark, guide, or docs set into a reusable skill.

Goal

Preserve the source's useful intent while rewriting the runtime shape for this repository, the Agent Skills format, and the selected execution shape.

Adaptation Checklist

Use the rows that affect runtime behavior, maintenance, or legal/attribution handling. Do not fill every row mechanically for trivial sources.

Decision Record
source intent what behavior the source is trying to cause
local target what the generated skill should cause in this repo or agent environment
fidelity boundary what must stay equivalent to the source
local replacement what should be rewritten to match local conventions
omitted material what was not carried forward and why
provenance source URL/path, version or commit when available, trust tier, confidence, and usage constraints
rights and attribution license, notice, attribution, or excerpt limits that affect bundled files

Rewrite Rules

  1. Do not copy the source's section structure unless that structure improves runtime behavior.
  2. Convert narrative instructions into decisions, checklists, examples, or output contracts.
  3. Replace source-specific tool names, paths, severity labels, or provider assumptions with local equivalents unless fidelity requires them.
  4. Keep provenance, rights notes, source versions, and fidelity tradeoffs in SOURCES.md.
  5. Keep only instructions that help the agent decide, do, or verify the task at runtime.
  6. If preserving benchmark or comparison behavior, state the invariant criteria and avoid tuning to expected answers.

Precision Check

Before authoring, answer:

  1. Which existing local rule should replace a source rule?
  2. Which source rule is too broad, stale, provider-specific, or non-runtime?
  3. Which added instruction prevents a concrete mistake that existing guidance does not cover?
  4. Which source detail belongs in SOURCES.md, SPEC.md, or a focused reference instead of SKILL.md?

If these answers are weak, tighten an existing file instead of adding new guidance.

README badge

README badge for getsentry/skills/skill-writer

Guides AI agents through a structured workflow for creating, updating, and iterating on agent skills—instruction files that extend AI coding capabilities. Includes reference files for synthesis, authoring, validation, and skill registration following the Agent Skills specification.

Generated from the current SKILL.md.

Does this skill help me write skills for Claude, or does it help Claude write skills?
This skill is loaded into Claude or another AI coding agent. It provides the agent with a standardized workflow, reference files, and decision trees for creating, updating, and iterating on skills that other agents can use.
What's the difference between create, update, synthesize, and iterate modes?
Create starts from scratch. Update modifies an existing skill. Synthesize gathers and structures source material before authoring. Iterate improves a skill based on positive, negative, or fix examples.
Do I need to read all the reference files?
No. The skill uses a step-by-step workflow that loads only the specific reference files needed for your operation. Start with mode-selection.md to determine your path, then load only the files it directs you to.
Can I use this skill to write skills for other AI providers, or only Claude?
The skill supports both provider-agnostic skills and Claude-specific mechanics. Provider-specific references are optional; the core workflow and execution shapes are portable across agents.
What does a completed skill output look like?
A skill consists of a SKILL.md file (the runtime router), optional focused reference files under references/, a SPEC.md for the maintenance contract, and optional scripts or templates. The skill-writer guides you through all artifact types and decides what belongs in each.
