harness-plan-brief

Generate a Plan Brief HTML for non-engineer vibecoders before implementation starts. Searches harness-mem (project-only) for relevant past decisions, patterns, and Plans archive entries, then renders a single-file HTML artifact summarizing understanding, options, risks, acceptance criteria, and confidence. Use when the user requests a planning preview, a non-engineer-friendly summary before approval, or says: plan brief, planning preview, 計画概要, 計画レビュー. Do NOT load for: actual implementation, code review, release work.

Quality

Content

63%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.

The body is a well-sequenced, actionable workflow with good failure handling, but it is verbose with embedded decision rationale and monolithic—detailed schema and cross-project logic that belong in separate reference files are inlined.

Suggestions

Move the full plan-brief-context.v1 schema and the cross-project alt-flow (Step 2 alt) into separate reference files and link to them one level deep, keeping SKILL.md an overview.

Trim decision-rationale blocks (e.g. 'D43 判断 1 の根拠') and redundant 重要 warnings to reduce token load; keep only execution-relevant constraints.

Add an explicit validate→fix→retry loop for the batch cross-project N-call path (e.g. retry/empty-group handling) to raise workflow clarity.

DimensionReasoningScore

Conciseness

Mostly actionable but padded with decision-rationale blocks ('D43 判断 1 の根拠…'), repeated 重要 warnings, and phase-number archaeology that Claude does not need to execute the skill.

3 / 5

Actionability

Provides concrete MCP search parameter blocks, a copy-paste jq example, and explicit script invocations; some cross-project steps are pseudocode loops rather than executable commands.

4 / 5

Workflow Clarity

Steps 1–6 are clearly sequenced with a per-failure behavior table and redaction validation, but there is no explicit validate→fix→retry feedback loop for the batch cross-project path.

4 / 5

Progressive Disclosure

No bundle files exist; the full schema, cross-project alt-flow, and failure table are inlined into a ~230-line monolith, and script/schema references point to non-bundled paths.

Description

100%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.

The description is specific, complete, and well-differentiated: it states concrete capabilities, gives natural multilingual trigger phrases, and scopes out conflicting use cases. It is a strong, low-conflict skill description.

DimensionReasoningScore

Specificity

Lists multiple concrete actions (searches harness-mem, renders single-file HTML, summarizes understanding/options/risks/acceptance criteria/confidence) with comprehensive coverage of what the skill does.

5 / 5

Completeness

Explicitly answers both 'what' (generate/search/render) and 'when' via a concrete 'Use when… or says: …' clause with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural trigger phrases a user would say ('plan brief', 'planning preview', '計画概要', '計画レビュー') covering English and Japanese synonyms.

5 / 5

Distinctiveness Conflict Risk

A clear niche (Plan Brief for non-engineers) with explicit anti-triggers ('Do NOT load for: actual implementation, code review, release work') minimizing wrong-skill conflict.
