Conciseness

The body is dense and imperative throughout — exact file paths, struct names, and commands with almost no filler, and it assumes competence (no explanations of what Kafka or migrations are). Minor trimming is possible in the RLS prose paragraph and the opening goal paragraph, so it sits at anchor 4 rather than 5's 'every token earns its place'.

Actionability

Fully executable guidance throughout: runnable code snippets for the router mounting and webhook wiring, exact commands ('cargo sqlx migrate add -r add_{kind}_trigger', './update_sqlx.sh', 'npm run generate-backend-client'), exact struct/trait signatures to implement, and copy-paste-ready pitfalls like '.route(path, post(h1).options(h2))'. Specific examples cover the common cases (push+pull via GCP, streaming via Kafka).

Workflow Clarity

A clearly sequenced 14-section checklist with reference implementations up front, per-section independence notes, a dedicated validation section with concrete commands, a UI smoke test, explicit feedback guidance ('the KINDS: [&str; N] length mismatch only surfaces when the crate compiles' → run full cargo check), and a final pre-PR checklist. This is a batch/risky operation and validation is fully covered.

Progressive Disclosure

No bundle files exist, and the single body is well structured with clearly signaled numbered sections and a stable {kind}/{Kind}/{KIND} convention, making it easy to navigate top-to-bottom. It does not reach 5 because all detail (the RLS policy deep-dive, the pitfalls catalog, the EE symlink workflow) is inlined in a ~280-line file where some of it could live in one-level-deep reference files.

Specificity

The description names a concrete action ('adding a new TriggerCrud-based trigger type') and enumerates the touch surfaces ('backend, frontend, CLI, and capture infrastructure') plus named providers (Azure, GCP, Kafka). It stops short of anchor 5 because it describes one composite checklist action rather than listing multiple individual capabilities.

Completeness

It explicitly answers both questions: the 'what' ('Checklist for adding a new TriggerCrud-based trigger type to Windmill') and the 'when' ('Use when wiring a new trigger kind across backend, frontend, CLI, and capture infrastructure') with concrete trigger contexts, in third person. This matches the anchor 5 example structure.

Trigger Term Quality

Natural keywords are present ('trigger type', 'wiring', 'new trigger kind', 'Azure, GCP, Kafka', 'Windmill', 'backend, frontend, CLI') — phrases a user adding a provider trigger would actually say. A few common variations (e.g., 'add a Kafka trigger', 'Event Grid', 'subscription trigger') are missing, so it does not reach anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The scope is clearly niche (Windmill, TriggerCrud-based, named cloud providers), so it is mostly distinct with minimal conflict risk. It does not reach 5 because a sibling 'native-trigger' skill exists for the same product and the description itself does not disambiguate the boundary — that disambiguation lives in the body.
