Claude Code Use Cases
AI coding assistant for code review, refactoring, and technical documentation
Use cases
Review the diff before you merge
Hand Claude Code the branch and ask for defects, missing tests, and anything a reviewer would bounce.
Turn the commits into release notes
Claude Code reads the commits since the last tag and writes notes a user could understand.
Explain what a dependency update actually changes
Claude Code reads a dependency bump and writes what behavior in your app could change.
Add tests to legacy code without refactoring it
Claude Code writes tests for untested legacy code and tells you which behavior it cannot safely assert.
Package a repeatable team SKILL.md for Claude Code
Claude Code turns a workflow your team already runs into a portable SKILL.md with triggers, guardrails, and a done checklist.
Keep one skill folder in sync for Codex and Claude Code
You maintain a single skills directory in git that both Codex and Claude Code are pointed at, with a short compatibility note for each tool.
Turn a Notion or Confluence runbook into a shared SKILL.md
Claude compresses a wiki runbook export into one SKILL.md with load instructions so Cursor and Claude Code read the same steps from git.
Gate a risky refactor with a characterization-test skill
Claude Code writes a SKILL.md that locks behavior with characterization tests before an agent refactors production paths.
Run a weekly competitor diff from one agent skill
A checked-in SKILL.md tells the agent to compare this week against your last diff file and return only new changes, each with a link.
Share one PR-description skill across Copilot, Cursor, and Claude Code
One SKILL.md in the repo defines how every coding agent writes PR bodies from a diff, with a short load line per tool.
Give agents a checked-in design-system SKILL.md
Cursor or Claude Code authors a design-system SKILL.md with tokens, component rules, and anti-slop guardrails so agent-built UI matches your product instead of generic AI chrome.
Keep secrets out of agent chat with env and a SKILL.md
Claude Code or Cursor follows a checked-in skill that forbids pasting DB and API secrets into chat: use .env, a secret manager, op run, or CI secrets, and reference variable names only.
Publish a portable SKILL.md pack from an MCP server
You ship a versioned skills folder from an MCP server or agent pack with digest metadata so clients discover verified skills without copying ad-hoc prompts.
Turn a Linear or GitHub issue into a skill brief
Cursor or Claude Code converts a ticket into a reusable SKILL.md section: acceptance criteria, fixtures, out-of-scope, and verification commands an agent can run repeatedly.
Gate agent work with a checked-in eval harness skill
Cursor or Claude Code authors a SKILL.md that points at versioned eval cases and a pass/fail rubric so coding agents cannot green a task by vibes alone.
Require green Playwright before an agent UI rewrite
A checked-in SKILL.md tells Cursor or Claude Code to run and extend Playwright coverage before it rewrites screens, with a stop rule if e2e fails mid-diff.
Generate a typed API client from OpenAPI via a repo skill
Claude Code or Cursor follows a SKILL.md that regenerates a typed SDK from your OpenAPI spec, with usage examples and a diff checklist agents run every time the spec changes.
Turn a postmortem into an on-call SKILL.md runbook
Claude compresses an incident postmortem into an executable SKILL.md runbook: detection signals, mitigation steps, escalation, and verify checks an agent or human can follow under pressure.
Review a Dependabot PR with a checked-in merge skill
Cursor or Claude Code follows a SKILL.md that reads the changelog, runs your real test commands, and blocks merge until breaking bumps get a migration note — not a blind approve.
Fix a failing GitHub Actions job with an agent CI skill
Claude Code or Cursor uses a SKILL.md that reproduces the failing workflow locally, edits YAML and scripts without disabling checks, and documents what broke and why.
Gate database migrations with a review SKILL.md
Cursor or Claude Code applies a SKILL.md before merging SQL or ORM migrations: expand-contract checks, lock risk, rollback path, and a dry-run against staging schema.
Triage a live alert with an on-call first-response skill
Claude or Cursor follows a SKILL.md when a page fires: confirm signal, narrow blast radius, safe mitigations first, and a status update template before deep debugging.
Review a Terraform plan with a blast-radius SKILL.md
Cursor or Claude Code follows a SKILL.md before terraform apply: destroy/replace counts, state drift, IAM expansion, and a merge-blocking summary for whoever holds the apply key.
Block insecure Dockerfiles with an agent security SKILL.md
Claude Code or Cursor applies a SKILL.md to Dockerfile and Compose diffs: non-root users, secret leakage in layers, pinned bases, and healthchecks — with merge-blocking findings.
Triage a Sentry issue into a minimal fix brief
Cursor or Claude Code follows a SKILL.md from a Sentry issue link: stack, breadcrumbs, and release — then writes a minimal repro and first-fix PR brief without catch-all error swallowing.
Draft a customer changelog from a git range via SKILL.md
Claude Code or Cursor follows a SKILL.md that reads a commit or merge range and drafts customer-facing changelog entries with categories and explicit breaking-change callouts.
Block insecure Kubernetes manifests with a security SKILL.md
Cursor or Claude Code applies a SKILL.md to k8s manifests and Helm values: privileged containers, hostPath mounts, capability grants, secrets in env, missing resource limits, and NetworkPolicy gaps.
Quarantine flaky tests with a triage SKILL.md
Cursor or Claude Code follows a SKILL.md from CI flake reports: isolate the flaky test, quarantine it with owner and ticket, propose root-cause checks for timing/state/order issues, and provide a re-enable checklist.
Find and remove stale feature flags with a cleanup SKILL.md
Cursor or Claude Code uses a SKILL.md to discover unused feature flags after launch: dead code paths, config drift, references in tests only, and a safe removal PR checklist.
Review npm dependencies for supply-chain risk with an audit SKILL.md
Cursor or Claude Code applies a SKILL.md to dependency PRs: new maintainers, suspicious postinstall scripts, lockfile-only changes without version bumps, typosquat package names, and a merge gate checklist.
Audit agent skill folders for SKILL.md casing on Linux CI
Cursor and Claude Code only load a skill when the file is exactly SKILL.md. An agent skill audits skill directories on Linux runners and fixes silent Unknown skill failures from skill.md or Skill.md.
Threat-model a third-party agent skill before you install it
Before copying a community SKILL.md into your repo, Claude Code or Cursor walks an install-review skill: open source repo, pin version, read SKILL.md and bundled scripts, and produce a go/no-go checklist.
Route agent work across cheap, mid, and max models with SKILL.md
Cursor or Claude Code loads a SKILL.md that assigns read-only and test tasks to a fast tier, refactors to a mid tier, and merge-gate or architecture work to max — cutting spend without hiding quality gaps.
Scan GitHub Actions workflows for secret exfil before merge
Cursor or Claude Code applies a SKILL.md on workflow PRs: hunt secret exfiltration, pull_request_target misuse, unpinned actions, and overbroad permissions — with a merge gate comment.
Review Next.js middleware auth before merge

Cursor or Claude Code applies a SKILL.md on webhook PRs: signature verification, idempotency keys, replay windows, and dual-write races — with merge-blocking findings.
Review Postgres RLS policies before merge
Cursor or Claude Code applies a SKILL.md on migration PRs with RLS: FORCE RLS, USING vs WITH CHECK gaps, role bypass, and tenant isolation holes — with merge-blocking findings.
Audit GitHub branch protection with an agent SKILL.md
Cursor or Claude Code applies a SKILL.md to audit branch protection and rulesets: required reviews, status checks, force-push, admin bypass, and CODEOWNERS gaps — before policy drift merges.
Review outbound URL fetchers for SSRF before merge
Cursor or Claude Code applies a SKILL.md on PRs that fetch a caller-supplied URL: private-network targets, redirect hops to metadata endpoints, and DNS rebinding — with merge-blocking findings.
Review file upload handlers for traversal and content sniffing
Cursor or Claude Code applies a SKILL.md on upload PRs: path traversal, trusted Content-Type headers, polyglot files, and public object ACLs — with merge-blocking findings.
Review Content-Security-Policy and security headers before merge
Cursor or Claude Code applies a SKILL.md on header diffs: script-src relaxations, unsafe-inline, missing frame-ancestors, and report-only policies that never enforce — with merge-blocking findings.
