Claude skills and agent skills

kieranklaassenSkill

ce-resolve-pr-feedback

kieranklaassen/compound-engineering-plugin/skills/ce-resolve-pr-feedback/SKILL.md

Judge PR feedback centrally, apply valid fixes, and complete review conversations with publication verified. Use when addressing feedback already left on a PR, preparing local fixes for a caller to publish, or completing a saved feedback batch. Use ce-code-review for reviewing code before feedback exists.

dotnetSkill

find-regression-risk

dotnet/maui/.github/skills/find-regression-risk/SKILL.md

Detects potential regression risks in a PR by cross-referencing lines the PR REMOVES against lines ADDED by recent labeled bug-fix PRs (`i/regression`, `t/bug`, `p/0`, `p/1`) touching the same files. Purely mechanical — no AI/LLM. Emits a CLEAN / OVERLAP / REVERT verdict plus structured findings. Triggers on: "does this PR revert a previous fix", "check PR for regression risk", "find regression risks in PR", "is this change reverting a bug fix". Do NOT use for: assessing ship-readiness of a release branch (use release-readiness), investigating CI failures (use azdo-build-investigator), or general code review (use code-review).

GitHubDeletes or force-pushesSkill

quality-playbook

github/awesome-copilot/skills/quality-playbook/SKILL.md

Run a complete quality engineering audit on any codebase. Derives behavioral requirements from the code, generates spec-traced functional tests, runs a three-pass code review with regression tests, executes a multi-model spec audit (Council of Three), and produces a consolidated bug report with TDD-verified patches. Finds the 35% of real defects that structural code review alone cannot catch. Works with any language. Trigger on 'quality playbook', 'spec audit', 'Council of Three', 'fitness-to-purpose', or 'coverage theater'.

moltbotSkill

autoreview

moltbot/clawdbot/.agents/skills/autoreview/SKILL.md

mengxi-reamSkill

adversarial-review

mengxi-ream/read-frog/.agents/skills/adversarial-review/SKILL.md

Adversarial code review using cross-model approach. Spawns reviewers on the opposing model (Claude uses Codex, Codex uses Claude) to challenge work from distinct critical lenses. Produces a synthesized verdict with findings and lead judgment. Triggers: "adversarial review".

affaan-mSkill

coding-standards

affaan-m/ECC/.agents/skills/coding-standards/SKILL.md

Baseline cross-project coding conventions for naming, readability, immutability, and code-quality review. Use detailed frontend or backend skills for framework-specific patterns. Use when reviewing code quality or naming with no framework-specific skill that applies.

GoogleSkill

review-duplication

google-gemini/gemini-cli/.gemini/skills/review-duplication/SKILL.md

Use this skill during code reviews to proactively investigate the codebase for duplicated functionality, reinvented wheels, or failure to reuse existing project best practices and shared utilities.

apacheSkill

patch-explainer

apache/cassandra/.claude/skills/patch-explainer/SKILL.md

Deep code analysis with ASCII visualizations showing structure, flow, and state transitions. Use when analyzing patches/diffs, explaining classes or subsystems, understanding code architecture, reviewing changes for inconsistencies, or when asked to visualize how code works. Provides before/after diagrams, data/control flow, concurrency analysis, assumptions, and failure modes. Triggers on explain this patch/code/class, how does X work, show me the flow, visualize this change, code review requests, or proactive analysis during PR reviews.

OpenAISkill

gpt-5-4-prompting

openai/codex-plugin-cc/plugins/codex/skills/gpt-5-4-prompting/SKILL.md

Internal guidance for composing Codex and GPT-5.4 prompts for coding, review, diagnosis, and research tasks inside the Codex Claude Code plugin

open-gsdSkill

gsd-pr-branch

open-gsd/get-shit-done-redux/skills/gsd-pr-branch/SKILL.md

Create a clean PR branch by filtering out .planning/ commits — ready for code review

rtk-aiSkill

code-simplifier

rtk-ai/rtk/.claude/skills/code-simplifier/SKILL.md

Review RTK Rust code for idiomatic simplification. Detects over-engineering, unnecessary allocations, verbose patterns. Applies Rust idioms without changing behavior.

tirth8205Skill

build-graph

tirth8205/code-review-graph/skills/build-graph/SKILL.md

Build or update the code review knowledge graph. Run this first to initialize, or let hooks keep it updated automatically.

nrwlSkill

review-local-branch

nrwl/nx/.claude/skills/review-local-branch/SKILL.md

Deep code review of the branch you are standing on, before it becomes a PR. Scope is merge-base..working-tree, so it covers commits, staged and unstaged changes together. Runs the same review lanes as review-pr — implementation, verification, approach, security — against the local checkout through the sandbox CLI, and saves a draft to ~/.nx-branch-reviews/<branch>.md. Use when asked to review "this branch", "my changes", or work that is not yet on GitHub.

coollabsioSkill

laravel-best-practices

coollabsio/coolify/.agents/skills/laravel-best-practices/SKILL.md

Apply this skill whenever writing, reviewing, or refactoring Laravel PHP code. This includes creating or modifying controllers, models, migrations, form requests, policies, jobs, scheduled commands, service classes, and Eloquent queries. Triggers for N+1 and query performance issues, caching strategies, authorization and security patterns, validation, error handling, queue and job configuration, route definitions, and architectural decisions. Also use for Laravel code reviews and refactoring existing Laravel code to follow best practices. Covers any task involving Laravel backend PHP code patterns.

humanlayerSkill

calldiff

humanlayer/humanlayer/.claude/skills/calldiff/SKILL.md

Diff call stacks across git commits for agentic code review (22 languages). Run `calldiff --help` for usage details.

Effect-TSSkill

effect-development

Effect-TS/effect/.agents/skills/effect-development/SKILL.md

pingdotggSkill

contribution-triage

pingdotgg/t3code/.agents/skills/contribution-triage/SKILL.md

Enforce T3 Code's PR contribution policy by closing ineligible submissions and triggering Macroscope review for eligible work within authorized scope. Supports explicit dry runs. Use for contribution moderation, not installation diagnostics or a full code review.

dyad-shReads credentialsSkill

dyad:multi-pr-review

dyad-sh/dyad/.claude/skills/multi-pr-review/SKILL.md

Multi-agent code review system that spawns three independent Claude sub-agents to review PR diffs. Each agent receives files in different randomized order to reduce ordering bias. One agent focuses specifically on code health and maintainability. Issues are validated using reasoned analysis rather than simple vote counting. Reports merge verdict (YES / NOT SURE / NO). Automatically deduplicates against existing PR comments. Always posts a summary (even if no new issues), with low priority issues in a collapsible section.

handsontableSkill

code-graph

handsontable/handsontable/.claude/skills/code-graph/SKILL.md

Query the pre-built code-review-graph knowledge graph (Tree-sitter, whole monorepo) instead of walking call chains with Grep+Read – 2-6x cheaper, and it catches dynamic dispatch that grep misses. Use for ANY task that spans multiple files, even when the user never mentions a graph or asks for it - fixing or tracing a bug ("fix this bug", "why does X happen", "trace this"), exploring unfamiliar code ("how does X work", "who calls X", "what imports Y", "where is X used or handled"), planning or doing a refactor ("rename X", "is it safe to change or remove X", "what would break", "blast radius", "find dead code"), or reviewing changes ("review this PR", "review this branch or diff"). When you are about to Grep for a symbol's callers, callees, or importers, use this skill.

GitHubSkill

agent-architecture

github/awesome-copilot/skills/agent-architecture/SKILL.md

Design AI agent architectures through requirements discovery, or audit and diagnose architectural flaws in existing agents. Architecture only; excludes implementation and general code review.
