This is a well-crafted skill that balances conciseness with actionability. The quick start is immediately executable, critical rules are specific and memorable, and progressive disclosure is exemplary with clear references to detailed guides. The main weakness is the workflow section, which could benefit from more explicit validation checkpoints and error recovery guidance, particularly around the build and release steps.

Suggestions

Add a validation/feedback loop to the workflow, e.g., after step 5 (sidecar setup): 'If bin entry fails, check package.json `bin` field and rebuild' — and after step 7 (release): 'Verify published package with `npx <pkg> --help`'.

Dimension	Reasoning	Score
Conciseness	The content is lean and efficient. It assumes Claude knows TypeScript, CLI concepts, and npm. Every section earns its place — no unnecessary explanations of what CLIs are or how libraries work. The critical rules are terse and actionable.	3 / 3
Actionability	Provides a fully executable minimal command example with real imports and runnable code. Critical rules are specific and concrete (e.g., 'check isCancel() after every @clack/prompts call'). The install command is copy-paste ready.	3 / 3
Workflow Clarity	The workflow lists clear sequential steps with references, and includes a verification step (run with --help). However, the verification is minimal — there's no feedback loop for error recovery, no validation of tab completion wiring, and no checkpoint after the build/release step. For a multi-step process involving build and release, this could be stronger.	2 / 3
Progressive Disclosure	Excellent structure with a concise overview in SKILL.md and well-signaled one-level-deep references to 8 specific reference files. The references section provides clear navigation with descriptive labels. Architecture is explicitly opt-in, preventing unnecessary complexity.	3 / 3

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is an excellent skill description that clearly defines its niche (TypeScript CLI development), lists specific concrete actions and tools, and opens with an explicit 'Use when' trigger clause. It covers both the development phase (command structure, prompts, tab completion) and the shipping phase (CI, versioning, release), giving comprehensive coverage without being verbose.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: command structure, interactive prompts, tab completion, CI gates, versioning (with named tools), and release strategies (npm or single-binary). Very concrete and actionable.	3 / 3
Completeness	Explicitly answers both what ('Guides command structure, interactive prompts, tab completion... CI gates, versioning, and release') and when ('Use when building TypeScript CLIs') with a clear trigger clause at the start.	3 / 3
Trigger Term Quality	Includes strong natural trigger terms users would say: 'TypeScript CLIs', 'command structure', 'interactive prompts', 'tab completion', 'CI gates', 'versioning', 'Changesets', 'release-please', 'npm', 'single-binary release'. Also names specific libraries (citty, @clack/prompts, @bomb.sh/tab) which are excellent triggers.	3 / 3
Distinctiveness Conflict Risk	Highly distinctive niche: TypeScript CLI development with specific libraries (citty, @clack/prompts, @bomb.sh/tab) and specific release tooling (Changesets, release-please). Very unlikely to conflict with other skills.	3 / 3
	Total	12 / 12 Passed
