Agent Claude Code
Reviews proposed target architectures and transformed code against modern best practice. Adversarial — looks for over-engineering, missed requirements, and simpler alternatives.
Agent Claude Code
Mines domain logic, calculations, validations, and policies from legacy code into testable Given/When/Then specifications. Use when you need to separate "what the business requires" from "how the old code happened to implement it.".
Agent Claude Code
Deep-reads legacy codebases (COBOL, Java, .NET, Node, anything) to build structural and behavioral understanding. Use for discovery, dependency mapping, dead-code detection, and "what does this system actually do" questions.
Agent Claude Code
Adversarial security reviewer — OWASP Top 10, CWE, dependency CVEs, secrets, injection. Use for security debt scanning and pre-modernization hardening.
Agent Claude Code
Writes characterization, contract, and equivalence tests that pin down legacy behavior so transformation can be proven correct. Use before any rewrite.
Command Claude Code
Full discovery & portfolio analysis of a legacy system — inventory, complexity, debt, effort estimation.
Command Claude Code
Generate a phased Modernization Brief — the approved plan that transformation agents will execute against.
Command Claude Code
Mine business logic from legacy code into testable, human-readable rule specifications.
Command Claude Code
Security vulnerability scan with a reviewable remediation patch — OWASP, CWE, CVE, secrets, injection.
Command Claude Code
Dependency & topology mapping — call graphs, data lineage, batch flows, rendered as navigable diagrams.
Command Claude Code
Multi-agent greenfield rebuild — extract specs from legacy, design AI-native, scaffold & validate with HITL.
Command Claude Code
Transform one legacy module to the target stack — idiomatic rewrite with behavior-equivalence tests.
Command Claude Code
Code review a pull request.
Agent Claude Code
Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality. Focuses on recently modified code unless instructed otherwise.
Command Claude Code
Cleans up all git branches marked as [gone] (branches that have been deleted on the remote but still exist locally), including removing associated worktrees.
Command Claude Code
Commit, push, and open a PR.
Command Claude Code
Based on the above changes, create a single git commit.

Onboard a Code-with-Gemini Makers Cardputer — fetch the build-with-gemini repo, flash firmware, and install the Gemini Buddy apps.
Skill Claude CodeCodex needs its repo
Iterate on the Cardputer-Adv MicroPython app bundle (Gemini Buddy, Snake, Hello) after the device is already provisioned via m5-onboard. Use when the user wants to add a new app, push a single changed .py without re-flashing, watch device serial logs, or run a one-shot REPL command. Trigger on "add an app", "push to…

End-to-end onboarding for a freshly-plugged-in M5Stack ESP32 device (Cardputer, Cardputer-Adv, Core, CoreS3, Stick) — detect on USB, flash UIFlow 2.0 firmware, and install the Gemini Buddy MicroPython app bundle. Use whenever the user plugs in or wants to flash/provision/reset an M5Stack or ESP32 board, or says…

Manage Discord channel access — approve pairings, edit allowlists, set DM/group policy. Use when the user asks to pair, approve someone, check who's allowed, or change policy for the Discord channel.
Skill Claude Code
Set up the Discord channel — save the bot token and review access policy. Use when the user pastes a Discord bot token, asks to configure Discord, asks "how do I set this up" or "who can reach me," or wants to check channel status.

An example slash command that demonstrates command frontmatter options (legacy format).
Skill Claude Code
An example user-invoked skill that demonstrates frontmatter options and the skills/ /SKILL.md layout.
