Plugin Instructions

These instructions apply when working under plugins/compound-engineering/. They supplement the repo-root AGENTS.md.

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

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 in Claude Code. Other targets may convert or map these references differently.

Command Naming Convention

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

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

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.

Skill Compliance Checklist

When adding or modifying skills, verify compliance with the skill 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)

Cross-Platform Reference Rules

This plugin is authored once, then converted for other agent platforms. Commands and agents are transformed during that conversion, but plugin.skills are usually copied almost exactly as written.

• Because of that, slash references inside command or agent content are acceptable when they point to real published commands; target-specific conversion can remap them.
• Inside a pass-through SKILL.md, do not assume slash references will be remapped for another platform. Write references according to what will still make sense after the skill is copied as-is.
• When one skill refers to another skill, prefer semantic wording such as "load the document-review skill" rather than slash syntax.
• Use slash syntax only when referring to an actual published command or workflow such as /ce:work or /deepen-plan.

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
