io.github.electric-sql/electric/designing-entities

Use when an app developer wants to build an entity (a.k.a. an agent) for their Electric Agents app — designing a single entity type, picking a coordination pattern when needed (single-agent, manager-worker, pipeline, map-reduce, dispatcher, blackboard, reactive-observer), defining state, handler, schemas, and implementing it in one entity file.

io.github.paxlabs-inc/matrix-core/automation-audit-ops

io.github.bluesky-social/atproto/testing

Testing practices for this monorepo — choosing between unit and end-to-end tests, where test files live, how tsconfig.test.json fits in, how to drive Playwright, to to write/adapt UI/end-to-end tests, and which test runner (vitest vs jest) to use. MUST be invoked BEFORE any code search or file reads whenever the user asks to add, write, or extend a test, add coverage, create a test file, set up testing in a new package, mentions vitest/jest, or refers to an existing `*.test.ts` file. Applies equally to unit tests and to end-to-end / UI tests — the skill routes to a Playwright-MCP-first discovery flow for the latter, which differs from normal code-search workflow.

io.github.medusajs/medusa/reviewing-prs

Reviews GitHub pull requests for the Medusa repository. Checks PR template compliance, contribution guidelines, code conventions, security, performance, and bugs.

io.github.giuseppe-trisciuoglio/developer-kit/typescript-security-review

Provides security review capability for TypeScript/Node.js applications, validates code against XSS, injection, CSRF, JWT/OAuth2 flaws, dependency CVEs, and secrets exposure. Use when performing security audits, before deployment, reviewing authentication/authorization implementations, or ensuring OWASP compliance for Express, NestJS, and Next.js. Triggers on "security review", "check for security issues", "TypeScript security audit".

io.github.EveryInc/compound-engineering-plugin/ce-doc-review

Review requirements or plan documents using parallel persona agents that surface role-specific issues. Use when a requirements document or plan document exists and the user wants to improve it.

io.github.go-vikunja/vikunja/api-v2-routes

Use when adding or changing a resource on the Huma-backed /api/v2 API (new endpoints, porting a v1 resource, editing pkg/routes/api/v2/). Covers per-operation Huma handlers, the shared envelopes, error/auth bridging, REST verb conventions, and what's automatic.

io.github.siddsachar/row-bot/mcp_guide

Guidance for using external MCP tools safely.

io.github.mukul975/Anthropic-Cybersecurity-Skills/designing-adversary-engagement-with-mitre-engage

Plan, run, and measure an adversary engagement operation using the MITRE Engage framework so that deployed deception is driven by strategy instead of deployed ad hoc. Covers the Engage Matrix (Prepare, Expose, Affect, Elicit, Understand), the 10-Step Operational Process, mapping engagement Activities to the ATT&CK techniques they expose, and defining measurable Goals and Operational Objectives. Use when a team has honeypots, honeytokens, or canary tokens but no coordinating strategy, when leadership asks "should we engage attackers and how", when building a deception/denial program, when writing an adversary engagement operation plan, or when deciding which deception Activities to deploy against a specific threat actor. Keywords: MITRE Engage, adversary engagement, cyber deception strategy, denial and deception, Engage Matrix, EAC, EGO, Expose Affect Elicit, deception program, honeypot strategy, engagement operation.

io.github.mukul975/Anthropic-Cybersecurity-Skills/deploying-cloud-deception-with-decoy-resources

Deploy cloud-native deception across AWS, Azure, and GCP using decoy (honey) resources whose only purpose is to generate a high-fidelity alert the instant an attacker touches them: canary IAM access keys, permission-less decoy users/roles/service principals, honey object-storage buckets, and decoy secrets in Secrets Manager / Key Vault / Secret Manager. Wires detection through CloudTrail + EventBridge, Azure Sentinel honeytoken watchlists + Defender, and GCP Cloud Audit Logs, so any use of a decoy is routed to the SOC with near-zero false positives. Use when protecting cloud accounts and data stores, when an org has only on-prem honeypots and needs cloud coverage, when seeding fake AWS keys to catch credential theft and code-leak exposure, or when detecting cloud reconnaissance and lateral movement. Keywords: cloud deception, canary token AWS, honey S3 bucket, decoy IAM credentials, CloudTrail alert, GuardDuty, Sentinel honeytoken, decoy secret, honey service account, cloud honeypot, breach detection.
