Code Review
Automated code review and analysis
dig
by udecode
Look up documentation and source code for libraries and packages. Use when the user asks a question about a library, needs to understand a library's API, or when you need information about a library that you don't know about. Triggers on questions like "How do I use X library?", "What's the API for Y?", "Show me how Z library handles this", or when encountering unfamiliar library usage.
checking-freshness
by astronomer
Quick data freshness check. Use when the user asks if data is up to date, when a table was last updated, if data is stale, or needs to verify data currency before using it.
authoring-dags
by astronomer
Workflow and best practices for writing Apache Airflow DAGs. Use when the user wants to create a new DAG, write pipeline code, or asks about DAG patterns and conventions. For testing and debugging DAGs, see the testing-dags skill.
tracing-downstream-lineage
by astronomer
Trace downstream data lineage and impact analysis. Use when the user asks what depends on this data, what breaks if something changes, downstream dependencies, or needs to assess change risk before modifying a table or DAG.
feature-verify
by sd0xdev
"Feature verification (READ-ONLY). Use when: verifying feature behavior, validating data integrity, confirming system state. Not for: modifying data (use feature-dev), code review (use codex-code-review). Output: verification report + confidence assessment."
codex-explain
by sd0xdev
"Explain complex code via Codex MCP. Use when: understanding complex logic, tracing data flow, onboarding to unfamiliar code. Not for: code review (use codex-code-review), exploration (use code-explore). Output: structured explanation at chosen depth."
codex-cli-review
by sd0xdev
"Code review via Codex CLI with full disk access. Use when: deep review needing full codebase read, uncommitted change review. Not for: quick diff review (use codex-code-review), doc review (use doc-review). Output: severity-grouped findings + merge gate."
doc-review
by sd0xdev
"Document review via Codex MCP. Use when: reviewing .md docs, tech spec audit, document quality check. Not for: code review (use codex-code-review), test review (use test-review). Output: 5-dimension rating table + gate."
claude-health
by sd0xdev
"Claude Code config health check. Use when: auditing .claude/ structure, checking naming, verifying hook setup. Not for: skill quality (use skill-health-check), code review (use codex-code-review). Output: health report + fix recommendations."
bug-fix
by sd0xdev
"Bug fix workflow. Use when: fixing bugs, resolving issues, regression fixes. Not for: new features (use feature-dev), understanding code (use code-explore). Output: fix + regression test + review gate."
next-step
by sd0xdev
"Change-aware next step advisor. Use when: user asks what to do next, workflow progression is unclear, session just started with dirty worktree. Not for: executing the suggested command (user decides), auto-loop decisions (hooks handle that). Output: findings-based suggestions or session summary with commit seed."
create-request
by sd0xdev
"Create or update request documents. Use when: planning features, tracking requests, updating progress. Not for: tech specs (use tech-spec), code implementation (use feature-dev). Output: request document with status tracking."
project-audit
by sd0xdev
"Project health audit with deterministic scoring. Use when: evaluating project quality, onboarding to new codebase, periodic health checks. Not for: runtime performance analysis, security-specific audits (use /codex-security). Output: 5-dimension score + actionable findings."
codex-implement
by sd0xdev
"Implement features via Codex MCP. Use when: writing new code from specs, implementing features, Codex-driven development. Not for: code review (use codex-code-review), architecture advice (use codex-architect). Output: implemented code + review loop."
test-review
by sd0xdev
"Test coverage review via Codex MCP. Use when: reviewing test sufficiency, identifying coverage gaps, test quality audit. Not for: generating tests (use codex-test-gen), code review (use codex-code-review). Output: coverage analysis + gap report."
git-investigate
by sd0xdev
"Git history investigation. Use when: tracking code changes, finding where bugs were introduced, root cause analysis. Not for: code exploration (use code-explore), issue analysis (use issue-analyze). Output: history trace + root cause report."
issue-analyze
by sd0xdev
"GitHub Issue deep analysis. Use when: analyzing issue root cause, classifying problems, investigation planning. Not for: fixing bugs (use bug-fix), code exploration (use code-explore). Output: classified analysis + investigation strategy."
skill-health-check
by sd0xdev
"Validate skill quality against routing, progressive loading, and verification criteria. Use when: auditing skills, checking skill health, reviewing skill design. Not for: code review (use codex-code-review) or doc review (use doc-review). Output: health report with per-skill ratings + Gate."
make-pr
by remix-run
Create GitHub pull requests with clear, reviewer-friendly descriptions. Use when asked to open or prepare a PR, especially when the PR needs strong context, related links, and feature usage examples. This skill enforces concise PR structure, avoids redundant sections like validation/testing, and creates the PR with gh CLI.
sweetviz
by vamseeachanta
Automated EDA comparison reports with target analysis, feature comparison, and HTML report generation for pandas DataFrames
content-strategy
by Logos-Liber
Documentation architecture, content planning, and maintenance strategies
learn
by udecode
Continuous learning system that extracts reusable knowledge from work sessions. Triggers: (1) /learn command to review session learnings, (2) "save this as a skill" or "extract a skill from this", (3) "what did we learn?", (4) After any task involving non-obvious debugging, workarounds, or trial-and-error discovery. Creates new Claude Code skills when valuable, reusable knowledge is identified.
review-pr
