po-feature-spec

Skill do Product Owner para especificação de features. Use quando precisar definir requisitos de negócio, escrever user stories, critérios de aceitação, priorização de backlog, ou qualquer documento de especificação de produto. Inclui fundamento de negócio para discovery: validação de hipótese, problema vs. necessidade, MVP, modelo de monetização e métricas pirata (AARRR) como input da spec. Trigger em: "nova feature", "especificação", "user story", "requisito", "backlog", "PO", "definir escopo", "critério de aceitação", "MVP", "roadmap", "validação de hipótese", "discovery", "monetização", "pricing", "product-market fit", "métricas AARRR".

Quality

Content

35%

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

This skill attempts to be comprehensive but suffers from significant verbosity, embedding extensive business theory (MVP philosophy, monetization models, AARRR metrics, product-market fit phases) that Claude already understands and that belongs in reference documents rather than the main skill file. The actionable elements (ambiguity formula, prioritization matrix, vertical slice examples, acceptance criteria format) are solid but buried in explanatory text. The workflow exists but is fragmented across sections rather than presented as a clear sequential process.

Suggestions

Extract the entire 'Fundamento de Negócio' section (sections 1-6) into docs/skill-guides/po-feature-spec.md and replace with a 3-5 line summary linking to it — this alone would cut ~50% of the content.

Add a concrete feature spec template (markdown skeleton with placeholders) that Claude can copy and fill in, rather than describing what the spec should contain in prose.

Consolidate the workflow into a single numbered sequence at the top: 1. Calculate ambiguity score → 2. Interview/Enrich if needed → 3. Validate business hypothesis → 4. Write spec using template → 5. Handoff to UI/UX, with clear go/no-go gates.

Remove explanations of concepts Claude already knows (what MVP means, problem vs. solution distinction, Maslow's hierarchy, what AARRR stands for) and keep only the project-specific rules and thresholds.

Conciseness

The skill is extremely verbose at ~300+ lines. It explains concepts Claude already knows (what a problem vs. necessity is, Maslow's pyramid, what MVP means, basic prioritization matrices). The 'Fundamento de Negócio' section alone is a wall of business theory that could be condensed to a fraction. Multiple sections restate obvious PO knowledge.

1 / 3

Actionability

The skill provides some concrete guidance like the ambiguity score formula, prioritization matrix, DADO/QUANDO/ENTÃO format for acceptance criteria, and vertical slice examples. However, most content is descriptive rather than executable — there are no code snippets, no template structures to fill in, and the spec output format is described abstractly rather than given as a concrete template.

2 / 3

Workflow Clarity

There is an implicit workflow (ambiguity scoring → deep interview/enrich → discovery validation → spec writing → handoff to UI/UX), but it's scattered across sections rather than presented as a clear sequential process. The ambiguity scoring thresholds and deep interview protocol provide some checkpoints, but there's no unified step-by-step workflow with explicit validation gates between phases.

2 / 3

Progressive Disclosure

The skill references several external files (docs/skill-guides/po-feature-spec.md, policies/vertical-slices.md, templates/deep-interview.md, docs/skill-guides/ideation-frameworks.md) which is good progressive disclosure practice. However, the main file itself contains too much inline content that should be in those referenced files — the entire 'Fundamento de Negócio' section with its 6 subsections is a prime candidate for extraction. No bundle files were provided to verify references exist.

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 a strong skill description that clearly defines its scope as a Product Owner specification tool, lists concrete actions and deliverables, and provides comprehensive trigger terms. It uses third person voice appropriately and includes both a 'Use quando' clause and an explicit trigger list, making it highly effective for skill selection among many options.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: defining business requirements, writing user stories, acceptance criteria, backlog prioritization, specification documents, hypothesis validation, MVP, monetization model, and AARRR metrics.

3 / 3

Completeness

Clearly answers both 'what' (Product Owner specification skill covering user stories, acceptance criteria, backlog prioritization, business discovery) and 'when' (explicit 'Use quando' clause plus a dedicated 'Trigger em' section with specific trigger terms).

3 / 3

Trigger Term Quality

Excellent coverage of natural trigger terms users would say, explicitly listed: 'nova feature', 'especificação', 'user story', 'requisito', 'backlog', 'PO', 'definir escopo', 'critério de aceitação', 'MVP', 'roadmap', 'validação de hipótese', 'discovery', 'monetização', 'pricing', 'product-market fit', 'métricas AARRR'. These are terms users would naturally use.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche as a Product Owner / product specification skill with distinct triggers like 'user story', 'critério de aceitação', 'métricas AARRR', 'discovery', and 'PO' that are unlikely to conflict with generic development or documentation skills.
