dotnetSkill

review-testing

dotnet/orleans/.github/skills/review-testing/SKILL.md

Testing lens for Orleans — spec-derived oracles, example tests, Accordant model-based tests, CsCheck property-based tests, deterministic simulation with controlled time, fault injection, and Verify snapshots. Use during code review, and when planning or writing tests.

AWSSkill

cdk-testing-review

aws/aws-cdk/skills/cdk-review/cdk-testing-review/SKILL.md

AWS CDK test-coverage reviewer. Use when a PR adds or changes tests (`**/*.test.ts`, `integ.*.ts`, `*.snapshot`) or ships new functionality, branches, feature-flag states, CFN properties, or cross-service behavior that should be tested — deciding first what coverage each change OWES (a unit test? an integ test? both? already covered? exempt?), then judging whether the PR's tests DISCHARGE it: meaningful assertions over non-asserting tests, edge/negative/feature-flag cases, required integ tests, snapshot-as-synthesized-template diffs, deploy-time assertions, and legitimate exemptions.

polarsourceSkill

billing-review

polarsource/polar/.agents/skills/billing-review/SKILL.md

Review a diff that touches Polar's billing domain — subscriptions, cycles and crons, orders, billing entries, meters and usage, discounts, checkout, payments and dunning, refunds, disputes, payouts, wallets, tax and invoices. Use before opening a PR that changes money movement or subscription lifecycle, when the user asks for a billing review, or when a reviewer needs the domain rules the team enforces in review but that no linter catches.

apacheSkill

shallow-review

apache/cassandra/.claude/skills/shallow-review/SKILL.md

Shallow (quick) ensemble bug-finding review using 6 specialist agents in parallel. Each specialist reviews the same patch through a different lens: Logic & Types, Boundaries & I/O, Concurrency & State, Resources & Serialization, Absence Analysis, and API Completeness. Findings are merged and deduplicated. Best for: quick first-pass review of patches, triage of diffs, broad surface-level bug scan. For deeper file-focused review with full pattern catalogs and codebase investigation, use the deep-review skill instead.

OpenMinedSkill

syft-pr-review

OpenMined/PySyft/.claude/skills/syft-pr-review/SKILL.md

Write a review document for a syft pull request. Takes a PR number or URL, reads the diff, and produces a checkbox-structured summary of the flows that changed with the new and changed code under each, the tests, and any code-standards problems in the new code. Use when the user says "review PR 1234", "write me a review doc for <PR link>", or "what changed in this PR".

GitHubReads credentialsSkill

security-review

github/awesome-copilot/skills/security-review/SKILL.md

AI-powered codebase security scanner that reasons about code like a security researcher — tracing data flows, understanding component interactions, and catching vulnerabilities that pattern-matching tools miss. Use this skill when asked to scan code for security vulnerabilities, find bugs, check for SQL injection, XSS, command injection, exposed API keys, hardcoded secrets, insecure dependencies, access control issues, or any request like "is my code secure?", "review for security issues", "audit this codebase", or "check for vulnerabilities". Covers injection flaws, authentication and access control bugs, secrets exposure, weak cryptography, insecure dependencies, and business logic issues across JavaScript, TypeScript, Python, Java, PHP, Go, Ruby, and Rust.

langfuse/langfuse/.agents/skills/security-review/SKILL.md

Review Langfuse changes for SSRF, tenant isolation, secret handling, unsafe redirects or uploads, RBAC drift, and client telemetry privacy. Use when a design or change accepts URLs or host fields, handles secrets or cross-tenant data, makes outbound requests, adds an integration, follows redirects, widens permissions, or can send customer-controlled UI data through analytics, monitoring, or session replay.

anthropics/knowledge-work-plugins/sales/skills/pipeline-review/SKILL.md

Stage-by-stage pipeline health check - coverage, aging, conversion, and at-risk deals - from CRM opportunity data. Use when the user asks "review my pipeline", "pipeline health", "where's my pipeline stuck", "weekly pipeline review", "which deals should I focus on this week", "any stale or stuck deals", "which deals have past close dates", "which deals are single-threaded", or "check my pipeline coverage against my number".

AnthropicSkill

win-loss-review

anthropics/knowledge-work-plugins/sales/skills/win-loss-review/SKILL.md

AnthropicSkill

review-reputation

anthropics/knowledge-work-plugins/small-business/skills/review-reputation/SKILL.md

Watches what customers are saying in public and in private, then does something about it. Aggregates Google, Yelp, and Facebook reviews alongside disputes, tickets, and email into themes backed by verbatim quotes; drafts a reply to every review in the owner's own voice for approval; spots customers who have gone quiet or look likely to leave; and drafts win-back offers for the ones worth keeping. With Shopify connected, order and fulfillment patterns become a sentiment signal too. Works from pasted or exported reviews when nothing is connected. Use this whenever the owner asks about reviews, ratings, reputation, complaints, or repeat business — including "what are people saying about us," "did we get any bad reviews," "how do I respond to this one-star," "our rating dropped," "which customers have gone quiet," "who hasn't ordered in a while," "how do I win them back," or "are customers happy."

thermo-nuclear-code-quality-review

nearai/ironclaw/.claude/skills/thermo-nuclear-code-quality-review/SKILL.md
