The body is lean and assumes Claude's competence — it states the do-not-edit rule, a numbered workflow, concrete task commands, and key toml sections without explaining concepts Claude already knows. Every token earns its place.

It gives fully executable, copy-paste-ready commands such as `task alef:generate`, `task alef:format`, and the freshness check `task alef:generate && git diff --exit-code packages/ crates/...`, plus exact rename mappings and toml section names.

The numbered 6-step workflow has an explicit validation checkpoint (step 5: run e2e tests) and a separate git-diff freshness check that acts as a feedback loop, so the batch regeneration operation is not left without verification.

The skill is under 50 lines with no bundle files and no need for external references, yet content is organized into clearly signaled sections (Workflow, Rename Mappings, Freshness Check, Key alef.toml Sections), satisfying the simple-skills exception.

The description lists multiple concrete actions — 'the regeneration workflow (task alef:generate / alef:format)', 'the Go DocumentExtractor→Extractor rename mapping', 'the git-diff freshness check', and 'the key alef.toml sections' — rather than vague language.

It answers both 'what' (the regeneration workflow, rename mapping, freshness check, alef.toml sections) and 'when' via the explicit 'Load before editing anything under packages/* or a binding crate, or when regenerating, formatting, or verifying Alef output' trigger clause.

It surfaces natural, domain-appropriate trigger phrases a developer would say — 'editing anything under packages/* or a binding crate', 'regenerating, formatting, or verifying Alef output' — alongside concrete task names.

The Alef-generated-bindings niche is narrow and the triggers (packages/*, binding crates, alef:generate/format) are distinct enough that it would not fire for unrelated skills.
