io.github.OpenBMB/PilotDeck/frontend-slides

Create animation-rich browser-based HTML presentations from scratch, enhance existing HTML decks, or convert PowerPoint files into web presentations. Use only when the requested deliverable is HTML or a browser presentation; do not use when the user needs an editable native .pptx file.

io.github.PostHog/posthog/writing-evals

Teaches how to write and run evals on the `products/posthog_ai/eval_harness/` harness — sandboxed agent suites that execute the real coding agent in a Docker or Modal sandbox against a seeded Hedgebox project, and one-shot suites that score a single in-process model invocation per case. Use when adding or changing eval suites, cases, scorers, seeders, or synthesizers under `products/posthog_ai/evals/` or `products/*/evals/`, when touching the harness under `products/posthog_ai/eval_harness/`, or when running or debugging those evals (`hogli evals`). Covers suite kinds and discovery, case anatomy, the seeder/synthesizer split, the one-branch scorer patterns, and how to read results. Not for `ee/hogai/eval/ci/` pytest evals, and not for the LLM Analytics product's evaluation features.

Use when interacting with MCP servers, executing tools, triaging findings, performing security reviews, debugging enterprise-managed authorization, deciding whether a CLI finding is real or overstated, or turning inspection output into an engineer-facing report with severity and confidence.

io.github.SawyerHood/dev-browser/dev-browser

Browser automation with persistent page state. Use when users ask to navigate websites, fill forms, take screenshots, extract web data, test web apps, or automate browser workflows. Trigger phrases include "go to [url]", "click on", "fill out the form", "take a screenshot", "scrape", "automate", "test the website", "log into", or any browser interaction request.

io.github.cartography-cncf/cartography/refactor-legacy

Convert a legacy handwritten-Cypher Cartography sync (`load_*` / `cleanup_*` JSON jobs) into the modern declarative data model (`load()`, `GraphJob.from_node_schema()`). Use when the user asks to refactor, modernise, migrate, or "clean up" a legacy intel module, or to remove a `cleanup/*.json` job tied to an old `MERGE` query.
