Compounding Engineering Plugin Development

Versioning Requirements

IMPORTANT: Routine PRs should not cut releases for this plugin.

The repo uses an automatied release process to prepare plugin releases, including version selection and changelog generation. Because multiple PRs may merge before the next release, contributors cannot know the final released version from within an individual PR.

Contributor Rules

Do not manually bump .claude-plugin/plugin.json version in a normal feature PR.
Do not manually bump .claude-plugin/marketplace.json plugin version in a normal feature PR.
Do not cut a release section in CHANGELOG.md for a normal feature PR.
Do update substantive docs that are part of the actual change, such as README.md, component tables, usage instructions, or counts when they would otherwise become inaccurate.

Pre-Commit Checklist

Before committing ANY changes:

No manual release-version bump in .claude-plugin/plugin.json
No manual release-version bump in .claude-plugin/marketplace.json
No manual release entry added to CHANGELOG.md
README.md component counts verified
README.md tables accurate (agents, commands, skills)
plugin.json description matches current counts

├── workflows-*/   # Deprecated aliases for ce:* skills
└── */             # All other skills

Note: Commands were migrated to skills in v2.39.0. All former /command-name slash commands now live under skills/command-name/SKILL.md and work identically (Claude Code 2.1.3+ merged the two formats).

Command Naming Convention

Workflow commands use ce: prefix to unambiguously identify them as compound-engineering commands:

/ce:plan - Create implementation plans
/ce:review - Run comprehensive code reviews
/ce:work - Execute work items systematically
/ce:compound - Document solved problems
/ce:brainstorm - Explore requirements and approaches before planning

Why ce:? Claude Code has built-in /plan and /review commands. The ce: namespace (short for compound-engineering) makes it immediately clear these commands belong to this plugin. The legacy workflows: prefix is still supported as deprecated aliases that forward to the ce:* equivalents.

Skill Compliance Checklist

When adding or modifying skills, verify compliance with skill-creator spec:

YAML Frontmatter (Required)

name: present and matches directory name (lowercase-with-hyphens)
description: present and describes what it does and when to use it (per official spec: "Explains code with diagrams. Use when exploring how code works.")

Reference Links (Required if references/ exists)

All files in references/ are linked as [filename.md](./references/filename.md)
All files in assets/ are linked as [filename](./assets/filename)
All files in scripts/ are linked as [filename](./scripts/filename)
No bare backtick references like `references/file.md` - use proper markdown links

Writing Style

Use imperative/infinitive form (verb-first instructions)
Avoid second person ("you should") - use objective language ("To accomplish X, do Y")

Cross-Platform User Interaction

When a skill needs to ask the user a question, instruct use of the platform's blocking question tool and name the known equivalents (AskUserQuestion in Claude Code, request_user_input in Codex, ask_user in Gemini)
Include a fallback for environments without a question tool (e.g., present numbered options and wait for the user's reply before proceeding)

Quick Validation Command

# Check for unlinked references in a skill
grep -E '`(references|assets|scripts)/[^`]+`' skills/*/SKILL.md
# Should return nothing if all refs are properly linked

# Check description format - should describe what + when
grep -E '^description:' skills/*/SKILL.md
