Names the domain (PRD/product requirements) and mentions some actions like 'discovery and drafting' along with specific outputs (product scope, user outcomes, requirement IDs, acceptance criteria), but the actions themselves are somewhat abstract—'standardize' and 'discovery' are vague compared to truly concrete actions like 'generate requirement IDs' or 'draft acceptance criteria tables'.

Clearly answers both 'what' (standardize PRD discovery and drafting for product scope, user outcomes, requirement IDs, and acceptance criteria) and 'when' (explicit 'Use when' clause listing creating PRD, product requirements, feature specification, or acceptance criteria plan).

Includes strong natural trigger terms that users would actually say: 'PRD', 'product requirements', 'feature specification', 'acceptance criteria plan'. These cover the most common ways a user would phrase requests in this domain.

The description carves out a clear niche around PRD creation and product requirements documentation with specific trigger terms like 'PRD', 'requirement IDs', and 'acceptance criteria' that are unlikely to conflict with other skills.

The content is lean and efficient. Every line serves a purpose—no explanations of what a PRD is, no padding. Bullet points are tight, examples are minimal but illustrative, and Claude's intelligence is respected throughout.

The skill provides structured guidance with specific steps (ask 3-5 questions, provide options, assign REQ-*/AC-* IDs, write to specific paths), but lacks concrete executable examples—e.g., no sample PRD snippet, no example of a well-formed REQ-* entry, no example of mapping to BRD objectives. The example given ('Target platform? a) Web b) Mobile c) Both') is helpful but insufficient for full actionability.

The three-phase workflow (Discovery → Drafting → Verification) is clearly sequenced with an explicit iterative loop in Discovery ('Repeat until Actionable State'), concrete filesystem operations in Drafting, and a mandatory verification checklist that serves as a validation checkpoint before completion. The anti-patterns section adds guardrails for error prevention.

References to `references/prd-template.md` and `references/checklist.md` are well-signaled and one level deep, which is good. However, no bundle files were provided, meaning these references point to non-existent files, undermining the actual utility of the progressive disclosure structure. The main content is appropriately concise for an overview but the missing referenced files weaken the score.
