Based on SOC occupation classification
Cut a skillmaker-studio release — version bump PR, v-tag push, release.yml build + npm publish, verification. Use when a maintainer asks to release a new version of skillmaker-studio to GitHub Releases and npm.
Drafts or revises a Skill Bundle's output/SKILL.md from its design.md. Use when handed a bundle's design.md (and optionally prior review revise notes) and asked to produce or update output/SKILL.md.
Researches a skill's topic and writes research/notes.md before design.md or SKILL.md is drafted. Use when handed a bundle's topic (bundle.json name/oneLiner and any existing design.md content) and asked to research it and write research/notes.md.
Decompose a decided plan, spec, issue, or design conversation into dependency-ordered tracer-bullet tickets written as local markdown files. Use when asked to "break this into tickets," "create implementation tickets," or "decompose into work items" — any time a decided scope needs slicing into executable vertical-slice tickets with blocking edges.
Design, evaluate, and ship agent skills with receipts using Skillmaker Studio. Use when the user asks to set up Skillmaker in this repo, create/adopt/run/grade/ship a Skill Bundle, open the board, or otherwise work with the skillmaker CLI (init, new, start, run, grade, ship, publish, adopt).
Drafts or revises a Skill Bundle's output/SKILL.md from its design.md. Use when handed a bundle's design.md (and optionally prior review revise notes) and asked to produce or update output/SKILL.md.

Determine target files. From the user's request, resolve the set of files to process -- either a single path or every source file under a given directory.
Check each file for an existing header. Read the first 20 lines of
each target file and look for the string SPDX-License-Identifier.
Skip files that already have a header. If SPDX-License-Identifier
appears in the first 20 lines, do not touch that file. Never add a
second header to a file that already has one.
Insert the header at the very top. For files that lack a header, insert these exact two lines as the first two lines of the file, above all existing content (including shebangs, comments, or blank lines):
// SPDX-License-Identifier: Apache-2.0
// Copyright (c) 2026 Acme Corp
The header must always be the very first thing in the file -- never insert it after existing content.
Report results. List which files were changed and which were skipped (already had a header).
