Claude-Codex Skills

Give your AI agent a clear finish line.

You ask for a fix and get a new abstraction. A review lists generic advice. The agent says “done,” but you still have to work out what it checked.

These skills give Claude Code and Codex a concrete way to finish the task: establish the intended outcome, work within scope, verify the result, and make remaining gaps explicit. Choose the skill for the problem in front of you.

What changes in your workflow

• A clearer target. Turn an idea, bug report, or incident into an outcome the agent can check.
• Focused work. Reuse existing capabilities, fix the owning cause, and remove what the change makes obsolete.
• A result you can assess. See the evidence, failed or unavailable checks, and remaining risks behind the verdict.
• Control over consequential actions. Reviews report findings; implementation stays within the agreed scope; publication and deployment follow their authorization boundaries.

Choose a route

Start where you need help. Each skill works independently; a small fix does not require a full lifecycle or audit.

For a larger task, combine only the steps needed to resolve decisions and produce evidence. Supplied requirements, existing designs, and current tests are valid starting points. Implementation includes its own verification; a separate test-building or review skill is optional.

Install

For a feature or fix, start with implementation-suite. Replace it with another plugin from Choose a route for a different task.

Claude Code:

/plugin marketplace add levnikolaevich/claude-code-skills
/plugin install implementation-suite@levnikolaevich-skills-marketplace
/reload-plugins

Codex:

codex plugin marketplace add levnikolaevich/claude-code-skills
codex plugin add implementation-suite@levnikolaevich-skills-marketplace

Invoke a skill by its full name: /implementation-suite:ln-41-surgical-change-implementer in Claude Code or $ln-41-surgical-change-implementer in Codex, followed by your task. For example: “Fix the total calculation when an item has a discount. Preserve the current rounding rules.”
