trellis-brainstorm

Guides collaborative requirements discovery before implementation. Creates task directory, seeds PRD, asks high-value questions one at a time, researches technical choices, and converges on MVP scope. Use when requirements are unclear, there are multiple valid approaches, or the user describes a new feature or complex task.

Quality

Content

81%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 process skill with strong sequencing, explicit validation gates, and a final convergence checklist. Its weaknesses are mild redundancy of the evidence rule across sections and the absence of worked examples (a sample question, a PRD skeleton) that would make the guidance fully copy-paste-ready.

Suggestions

Consolidate the evidence-before-asking rule into one authoritative section; it is currently stated three times (Non-Negotiable Evidence Rule, Planning Flow steps 2-3, Question Rules), which costs tokens without adding information.

Add one worked example of a well-formed single question showing the required parts (decision needed, why it matters, recommended answer, trade-off) to lift actionability to fully executable.

Consider moving the First Principles Analysis framework and the detailed artifact content lists into a reference file (e.g., references/first-principles.md, references/artifacts.md) so SKILL.md stays a lean overview.

DimensionReasoningScore

Conciseness

The body is dense, imperative, skill-specific process guidance with no explanation of concepts Claude already knows, but the evidence-before-questions rule is restated across the Non-Negotiable Evidence Rule, Planning Flow steps 2-3, and Question Rules sections — minor over-explanation that could be trimmed, placing it at the efficient anchor rather than the lean anchor.

4 / 5

Actionability

It provides a copy-paste-ready command ('TASK_DIR=$(python3 ./.trellis/scripts/task.py create ...)'), exact artifact filenames, and concrete per-artifact content lists, but lacks a worked example of a well-formed single question or a PRD skeleton, leaving minor gaps against the fully-executable anchor.

4 / 5

Workflow Clarity

The 8-step Planning Flow is clearly sequenced, and the PRD Convergence Pass plus the Quality Bar act as explicit validation gates before 'task.py start', including a feedback loop (rewrite prd.md, re-read top to bottom, verify no duplicated facts or lost anchors) — matching the explicit-validation-and-feedback-loops anchor.

5 / 5

Progressive Disclosure

The body is well-organized with clear section headers and no external references to mismanage (no bundle files exist), but at ~170 lines the first-principles framework and detailed artifact rules are candidates for separate reference files to slim the overview, leaving minor organization gaps relative to the ideal overview-plus-references split.

Description

88%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 description that pairs a concrete, comprehensive action list with an explicit trigger clause in third-person voice. The only weakness is trigger-term coverage missing the most obvious synonyms a user would actually say.

Suggestions

Add natural trigger synonyms users would say, especially 'brainstorm' and 'planning' (e.g., 'Use when the user wants to brainstorm or plan a new feature'), since 'trellis-brainstorm' is the skill's own name yet the word never appears in the description.

Consider naming the artifacts users would recognize (PRD, requirements doc, design doc) in the 'when' clause to strengthen triggering on artifact-oriented requests.

DimensionReasoningScore

Specificity

The description lists five concrete actions covering the full workflow — 'Creates task directory, seeds PRD, asks high-value questions one at a time, researches technical choices, and converges on MVP scope' — with no coverage gap, matching the comprehensive-actions anchor rather than the minor-gaps anchor one level below.

5 / 5

Completeness

It explicitly answers both 'what' (guides requirements discovery with five named actions) and 'when' ('Use when requirements are unclear, there are multiple valid approaches, or the user describes a new feature or complex task') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Triggers like 'requirements are unclear', 'multiple valid approaches', 'new feature or complex task' are natural user phrasing, but common synonyms such as 'brainstorm' (the skill's own name) and 'planning' are missing, so it falls just short of comprehensive synonym coverage.

4 / 5

Distinctiveness Conflict Risk

Terms like 'requirements discovery', 'seeds PRD', and 'MVP scope' carve a distinct pre-implementation planning niche with minimal conflict risk, though it could mildly overlap with generic planning or spec-writing skills.
