We've started an effort at Chrome to equip agents with this key domain knowledge and we're shipping our 1.0 today, in partnership with Firefox, MDN and Edge. 200+ manual implementation guides (~1.7MB), best performing from network experts, updated as the network evolves. (open source, obv, so we'll welcome your bike too); Read versions here: [1] I have spent the last 9 months on how to port this as the Agent + (Agentic RAG) CLI skill without blowing up your context window. (or cedeing activation mechanics to search MCP dynamic tool). The description of the skill is to act on relevant front tasks. RAG's work I'm quite proud... Originally a 500mm stack near package - 7MB pure-JS - 10ms lookup on your CPU. We just introduced "legit-scan" (trained on 30k github repos) to detect old "painful" patterns that your agent can renew. (92% to be exact on streak.) People make a lot of claims about what players do good/bad. We wanted receipts, so we invested heavily in ash [2] to help us hill, but also to recognize when the knowledge is common enough, we can correct our guides.
