Claude C-Suite Plugin

version license commands

Executive team perspectives for any codebase. Thirteen specialized review commands plus a single-CxO router (/ask) that analyze your project from different leadership viewpoints.

📝 Read the story (JP): Claude Codeに「経営会議」を持ち込む — claude-c-suite-plugin を作った話

60-second quick start

/plugin marketplace add JFK/claude-c-suite-plugin
/plugin install claude-c-suite

Then in any git repository:

/claude-c-suite:ceo

The CEO command auto-diagnoses your project, picks the 3 most relevant executive perspectives, and gives you a prioritized action list. When in doubt, start with /ceo — it's the safe, always-correct entry point.

For the full guide (decision tree, common patterns, multi-role consultation, plugin combinations, troubleshooting), see USAGE.md (日本語版).

Commands

Role Details

CEO (Meta-Layer) and Router

  • CEO — Sits above the cross-reference graph, not inside it. Triages the user's need to the 3 most relevant CxO perspectives, analyzes through those lenses, and synthesizes a unified executive decision. Does not perform specialized analysis — knows which experts to consult and how to resolve conflicts between them. "The right 3 perspectives beat all 11 spread thin"
  • /ask (Router) — The lightweight cousin of /ceo. Auto-routes a single question to the one best-fit CxO/Lead and answers from that single lens. Use it when you have a question but don't want to think about which expert to call. Cheaper than /ceo (one lens vs three) and easier than calling a role directly (no org-chart memorization). Declines routing and redirects to /ceo when the question genuinely needs synthesis. "One sharp lens beats three blurry ones"

Strategy & Management

  • CTO — Guards codebase health. Identifies tech debt that compounds over time, evaluates architecture decisions, and prioritizes refactoring. "Debt compounds"
  • PM — Steers the ship to release. Triages milestones, orders issues by impact, and ensures bugs are fixed before features ship. "Bugs before features"
  • CFO — Hunts down waste. Finds N+1 queries, idle resources, missing caches, and audits billing logic for correctness. "Every query has a price tag"
  • CIO — Governs information architecture. Reviews data models, schema health, migration safety, system integration contracts, and data lifecycle. "Schema is the contract between past and future"

Security & Legal

  • CSO — Thinks like an attacker. Audits auth flows, scans for hardcoded secrets, checks dependencies against OWASP Top 10. "Secrets are toxic"
  • CLO — Eliminates legal exposure. Maps dependency license trees for copyleft conflicts, assesses GDPR/CCPA readiness, and verifies IP provenance. "Licenses are viral"

Product & Design

  • CDO — Enforces design consistency. Reviews component reuse, design token adherence, and UX coherence across the app. "Components are contracts"
  • CMO — Makes the product discoverable. Checks SEO fundamentals, Core Web Vitals, OGP/social sharing, and analytics instrumentation. "Speed is conversion"

Operations & AI

  • COO — Keeps production running. Audits CI/CD pipelines, deployment strategies, observability coverage, and incident readiness. "Deploys should be boring"
  • CAIO — Governs AI responsibly. Reviews model lifecycle, prompt engineering quality, bias detection, eval suites, and guardrails. "Prompts are production code"

Leads (report to CxOs)

  • QA Lead — Closes testing gaps. Measures coverage, identifies missing test scenarios, and evaluates the testing strategy holistically. "Every bug is a missing test"
  • DX Lead — Champions developer happiness. Reviews API ergonomics, error messages, SDK usability, and onboarding friction. "Pit of success"

Installation

/plugin marketplace add JFK/claude-c-suite-plugin
/plugin install claude-c-suite

Required GitHub token scopes

The plugin issues gh commands to read issues, milestones, and labels. Most commands are read-only; /pm is the only command that may suggest write operations (gh issue create, gh issue edit), and only after explicit user confirmation.

Use case Recommended scopes
Public repos only public_repo
Private repos repo
Organization repos repo + read:org

See SECURITY.md for the full threat model and the vulnerability reporting process.

Question mode — ask anything

Each role answers natural-language questions from its perspective, grounded in your actual codebase:

/claude-c-suite:ask Is this SQL schema normalized correctly?
/claude-c-suite:ask How risky is the new dependency we just added?
/claude-c-suite:ceo Are we ready to launch?
/claude-c-suite:cto Should we migrate to a monorepo?
/claude-c-suite:pm Should we delay the launch to fix these bugs?
/claude-c-suite:cso Is our JWT implementation secure?
/claude-c-suite:clo Can we use this GPL library in our SaaS product?
/claude-c-suite:cfo Are we over-provisioned on our database tier?
/claude-c-suite:caio Are we handling prompt injection risks?

Cross-Reference Map

Each role cross-references its Top 3 collaborators — the 3 roles it works most closely with. The CEO sits above as a meta-layer, reading the graph to select the right perspectives for any given need.

Configuration

Set a default output language for all C-Suite commands via ~/.claude/claude-c-suite.json:

/claude-c-suite:config init   # creates the template

Then edit to your preference:

{
  "version": "1.5.0",
  "language": "ja"
}
Key Values Default
language ISO 639-1 code (en, ja, zh, ko, es, fr, de, …) Auto-detect from question
version Plugin version stamp (informational) Set by init
  • If the file is missing or malformed, commands silently fall back to auto-detecting the language from the user's question.
  • Prose, explanations, and recommendations are translated; code blocks, file paths, CLI commands, and structural headings stay in English.
  • Run /claude-c-suite:config to see the current effective config.

Design Principles

  • Analysis only — Commands recommend actions but never execute changes
  • Cross-referencing — Run multiple commands in one session; they reference each other's findings
  • GitHub-native — Uses gh CLI to gather issues, milestones, and commit history
  • Universal — No project-specific assumptions; works with any codebase

Documentation

Document Purpose
USAGE.md / USAGE.ja.md Full usage guide — quick start, decision tree, patterns, troubleshooting
SECURITY.md Threat model, mitigations, GitHub token scopes, vulnerability reporting
CONTRIBUTING.md Style guide, feature freeze policy, PR workflow
CHANGELOG.md Release history (v1.0 → present)
AUDIT.md Conformance audit matrix and verifier (python3 scripts/audit.py)

Related plugins

  • claude-phd-panel — Academic review (Distributed Systems, Statistics, Database Theory, etc.). Findings are auto-incorporated by C-Suite commands when run in the same session.
  • expert-craft — Create your own custom domain experts that integrate with C-Suite cross-references.
