platform/ — std::env::var is banned elsewhere. Config/paths via platform/config.rs (data_dir()).net/ — reqwest::Client is banned elsewhere. Use net/http.rs (shared() / build_client()).Result<_, String> is banned outside error/. Use AppError/AppResult from error.rs.Business logic, processing pipelines, ATS analysis, and document generation live in Rust. The TS renderer stays presentation-only. Flag any business logic drifting into the frontend.
Respect the layer model in docs/architecture-rules.md; new cross-layer coupling is HIGH. L0 platform/net/error → L1 domain → L2 services/commands → L3 entrypoints.
New board scraper → scraping/boards/mod.rs (SCRAPERS, implement Scraper). Register, don't special-case. (No applier registry — the apply engine was removed.)
Migrations forward-safe and reversible-or-guarded; *Store writes go through the data layer, not ad-hoc SQL in commands. SQLite work off the async runtime (spawn_blocking).
Use observability.rs (Span) for tracing; don't invent ad-hoc logging.

Skill source recorded
Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.
Review before install: Avoid automatic install
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
Version reported in registry metadata; check source releases before relying on it.
