Last week I spent 14 hours on repetitive dev tasks — writing boilerplate tests, reviewing PRs, generating docs, debugging deploys. This week I spent 3. The difference? Five Claude Code skills I found (and one I built myself) that automate the painful parts.
Here are the exact skills, what they do, and how to install them in under 30 seconds.
1. Code Review — The Adversarial Reviewer
The problem: Self-reviewing your own PRs is like proofreading your own essay. You see what you meant to write, not what you actually wrote.
What this skill does: Runs a senior-engineer-level adversarial review on your changed files. It checks for logic bugs, security issues, performance problems, missing edge cases, and naming inconsistencies. Not a linter — it thinks about your code the way a skeptical colleague would.
Real example: I had a Go handler that returned 200 OK on a database write failure because the error check was on the wrong variable. The skill caught it in 4 seconds. A human reviewer might have missed it on a Friday afternoon.
Install:
npx tokrepo search code review
npx tokrepo install <skill-id>
Or browse it at tokrepo.com and copy the one-liner from the asset page.
2. Git Workflow — Commit Messages That Actually Help
The problem: git log full of "fix stuff", "WIP", and "update things". Six months later you have no idea why anything changed.
What this skill does: Analyzes your staged changes, generates a conventional commit message with scope, explains the why not just the what, and optionally creates a PR description. It follows your repo's existing commit style.
Real example: I staged 4 files across 2 directories. Instead of writing "update auth and fix redirect", the skill generated:
fix(auth): resolve OAuth callback redirect loop when session cookie expires
The callback handler was not clearing stale session tokens before
writing new ones, causing an infinite redirect on expired sessions.
That's a message future-me will actually thank present-me for.
Install:
npx tokrepo search git workflow
npx tokrepo install <skill-id>
3. Test Generation — Coverage Without the Tedium
The problem: You know you should write tests. You also know it's 6pm and you'd rather do literally anything else.
What this skill does: Reads your implementation, identifies the critical paths and edge cases, then generates test files with proper setup/teardown. Supports Jest, Vitest, Go testing, and pytest. It doesn't just test the happy path — it generates boundary tests, error cases, and concurrency scenarios.
Real example: For a Nuxt 3 composable that fetches and caches API data, it generated 11 test cases covering: successful fetch, network failure, cache hit, cache expiry, concurrent requests, malformed response, and empty result set. Took me 90 seconds to review and merge vs. 40 minutes to write myself.
Install:
npx tokrepo search test generation
npx tokrepo install <skill-id>
4. Documentation — From Code to Readable Docs
The problem: Your code is self-documenting (it's not). Your teammates can just read the source (they won't). The README was last updated in 2024.
What this skill does: Scans your codebase structure, public APIs, and type definitions, then generates documentation that's actually useful. It creates function references, architecture overviews, setup guides, and API docs. It respects JSDoc/GoDoc/docstring conventions.
Real example: I pointed it at a Go-Zero microservice with 23 endpoints. In 2 minutes I had a complete API reference with request/response examples, auth requirements, and error codes. Previously this was a "we'll do it later" task that never got done.
Install:
npx tokrepo search documentation
npx tokrepo install <skill-id>
5. Deployment — Pre-flight Checks That Catch Problems Early
The problem: "Works on my machine" followed by a 2am production incident.
What this skill does: Runs a structured pre-deployment checklist: environment variable validation, dependency audit, build verification, migration status check, and smoke test generation. It's not a CI/CD replacement — it's the human checklist you forget to follow when you're rushing to ship.
Real example: Before deploying a Nuxt 3 SSR app, the skill caught that my .env.production was missing a new API key I'd added during development. Without it, the app would have booted fine but silently failed on every authenticated request. That's a subtle bug that takes hours to diagnose in production.
Install:
npx tokrepo search deployment
npx tokrepo install <skill-id>
Where These Skills Live
All five are available on TokRepo — an open registry of 200+ AI skills, prompts, MCP configs, and scripts. Think of it as npm for AI workflows.
You can browse the full catalog at tokrepo.com/en/featured or search from your terminal:
npx tokrepo search <keyword>
Each asset page has a one-click install command. Skills get saved to your Claude Code config, and you can start using them immediately.
What I Learned
The skills that save the most time aren't the flashy ones. They're the ones that automate the tasks you already know how to do but dread doing. Code review, commit messages, test writing, docs, deploy checks — none of these are hard. They're just tedious enough that you cut corners.
The compound effect is real. Five skills, each saving 30-60 minutes per week, adds up to an extra day of productive work every month.
If you've built a skill that saves you time, consider sharing it on TokRepo. The registry is open and every contribution helps the community.
