Reference for the local external-source repos that are ground truth for Krypton's vendored deps and prior art — pi-mono (@mariozechner/pi-agent-core, pi-ai, pi-coding-agent), pretext (@chenglou/pretext text layout/measurement), Zed editor (ACP / MCP / agent-server / model-selection prior art), Obsidian Web Clipper (browser clipping, extraction, template rendering, Obsidian handoff), and Omnigent (multi-agent orchestration, native harnesses, Polly/Debby/Scribe examples). Use when working on src/agent/, debugging agent events, adding tools, or changing models/providers (pi-mono); creating text layouts/animations, measuring text without DOM, or rendering text to canvas/SVG (pretext); studying how Zed implements ACP, MCP context-server forwarding, external agent servers, or model selection for the ACP harness (zed); designing clipping/import flows, Markdown extraction, template engines, browser-extension surfaces, highlights, or Obsidian URI/CLI handoff (obsidian-clipper); or designing multi-agent orchestration,

Before writing any code for a new feature or significant improvement, perform deep research then write an implementation specification in docs/ and wait for explicit user approval. No code is written until the spec is approved.

Performance audit checklist for each window/view implementation. Run against a specific view or all views to identify rendering bottlenecks, leaked listeners, missing cleanup, and animation issues.
