typescript-pro

Implements advanced TypeScript type systems, creates custom type guards, utility types, and branded types, and configures tRPC for end-to-end type safety. Use when building TypeScript applications requiring advanced generics, conditional or mapped types, discriminated unions, monorepo setup, or full-stack type safety with tRPC.

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, actionable body: executable examples, a workflow with real validation checkpoints, and clean progressive disclosure into verified reference files. The only bloat is the redundant 'Knowledge Reference' keyword list.

Dimension	Reasoning	Score
Conciseness	Mostly lean with tight, copy-paste code and short inline comments that earn their place, but the trailing 'Knowledge Reference' keyword dump partially restates the description and could be trimmed.	4 / 5
Actionability	Fully executable, copy-paste-ready examples (branded types, type guards, discriminated unions, utility types, tsconfig.json) plus concrete commands (`tsc --noEmit`, `type-coverage`) cover the common cases.	5 / 5
Workflow Clarity	The five-step Core Workflow is clearly sequenced with explicit validation checkpoints ('run tsc --noEmit to catch type errors before proceeding', 're-run…to confirm zero errors') and a feedback loop ('iterate on steps 3–4 until all checks pass').	5 / 5
Progressive Disclosure	SKILL.md is an overview with a Reference Guide table clearly signaling five one-level-deep reference files (all present on disk) with explicit 'Load When' conditions, making navigation easy.	5 / 5

Description

92%Weight 40%Scale 1-5

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

A strong, specific description that pairs concrete capabilities with an explicit 'Use when' trigger clause and a well-scoped niche. Only minor gap is the absence of file-extension synonyms that would round out trigger coverage.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'implements advanced TypeScript type systems, creates custom type guards, utility types, and branded types, and configures tRPC' — covering the skill comprehensively rather than gesturing vaguely.	5 / 5
Completeness	Explicitly answers both 'what' (implements/creates/configures…) and 'when' ('Use when building TypeScript applications requiring…') with concrete trigger phrases, matching the top anchor.	5 / 5
Trigger Term Quality	Strong natural terms ('TypeScript applications', 'generics', 'conditional or mapped types', 'discriminated unions', 'monorepo setup', 'tRPC') that users would actually say, but missing file-extension synonyms like '.ts' or 'tsconfig' that would push it to a 5.	4 / 5
Distinctiveness Conflict Risk	Occupies a clear niche — advanced TS type systems plus tRPC end-to-end type safety — with distinct, specific triggers and minimal overlap with sibling skills.	5 / 5
	Total	19 / 20 Passed
