blueprint

Turn a one-line objective into a step-by-step construction plan any coding agent can execute cold. Each step has a self-contained context brief — a fresh agent in a new session can pick up any step without reading prior steps.

Quality

Content

60%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-structured, readable overview with a clear phase sequence, an explicit review gate, and concrete invocation and installation commands. Its main weaknesses are missing core process detail (the plan template and context-brief format are never shown), externalized references that leave the skill dependent on a GitHub repo, and mild promotional padding in the Key Differentiators section.

Suggestions

Show (or bundle) the actual plan template and one worked example of a step's 'self-contained context brief' so an executing agent has concrete output structure rather than only phase names.

Bundle key reference files locally (e.g. examples/small-plan.md, the template) instead of linking to GitHub, so the skill works offline and references are one level deep.

Trim the 'Key Differentiators' marketing section and the Overview that repeats the description verbatim, folding any operationally useful content (mutation protocol, fallback behavior) into the workflow steps.

DimensionReasoningScore

Conciseness

The body is mostly efficient — phase list, usage examples, and a crisp ✅/❌ best-practices list — but includes unnecessary padding: the Overview repeats the frontmatter description nearly verbatim, and the 'Key Differentiators' section is promotional copy ('Zero runtime risk', 'Cold-start execution') rather than instructions. This matches anchor 3 (some unnecessary explanation that could be trimmed) rather than 4, since a whole marketing section is more than a minor instance.

3 / 5

Actionability

Concrete guidance exists for invoking the skill ('/blueprint myapp "migrate database to PostgreSQL"') and installing it (git clone command), but the core deliverable process is only described at phase-headline level — 'Generates the plan from a structured template' without ever showing the template, step format, or what a context brief contains. This matches anchor 3 (some concrete guidance, key details missing); it is above anchor 2 because real, executable commands and examples are present, but below anchor 4 because the central instructions are absent.

3 / 5

Workflow Clarity

The five phases (Research → Design → Draft → Review → Register) are clearly sequenced, and 'Review — Delegates adversarial review to a strongest-model sub-agent' is an explicit checkpoint gate with a fallback behavior. It matches anchor 4 (clear sequence, most checkpoints present, minor validation gaps) rather than 5, which would require explicit validation steps and error-recovery feedback loops, and the skill involves no destructive or batch operations that would cap the score at 3.

4 / 5

Progressive Disclosure

Sections are well organized with clear headers, and the 'Additional Resources' section clearly signals where examples live — but those references are external GitHub URLs (examples/small-plan.md, large-plan.md) rather than bundled reference files, so the detailed material is unavailable to the agent reading the skill offline. This sits at anchor 4 (good structure, references mostly clear, minor gaps); it does not reach anchor 5's well-bundled one-level-deep references and is above anchor 3, since references are clearly signaled and the body is appropriately overview-sized.

Description

50%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 communicates a clear and distinctive core capability — cold-start construction plans with per-step self-contained briefs — in a compact, non-padded way. However, it lacks any 'Use when...' trigger guidance, which both caps completeness and limits its trigger-term quality, and its action coverage is narrower than the skill's actual capabilities.

Suggestions

Add an explicit 'Use when...' clause, e.g. 'Use when a task needs 3+ PRs across sessions, when multiple agents must share execution, or when the user asks for a project plan or step-by-step breakdown.'

Broaden trigger-term coverage with natural synonyms users would say: 'plan this project', 'break this objective down', 'task decomposition', 'multi-session project', 'rollout plan'.

Mention one or two more concrete capabilities from the body (e.g. dependency detection and parallel step identification, adversarial plan review) to lift specificity beyond the current two actions.

DimensionReasoningScore

Specificity

The description names the domain (construction plans for coding agents) and two concrete actions — 'Turn a one-line objective into a step-by-step construction plan' and 'Each step has a self-contained context brief' — but omits the research, design, review, and tier-assignment capabilities the skill actually has. It sits at anchor 3 (domain plus 1-2 concrete actions, not comprehensive) rather than 4, which requires several specific listed actions, and is clearly above anchor 2, which would only name the domain.

3 / 5

Completeness

The 'what' is clear and concrete (generate step-by-step plans with self-contained per-step briefs), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It does not reach anchor 4 because 'when' is entirely absent rather than merely implicit or under-specified.

3 / 5

Trigger Term Quality

Natural phrases like 'step-by-step', 'plan', 'objective', and 'coding agent' are present, but common variations a user would actually say — 'break this down', 'project plan', 'task decomposition', 'multi-PR' — are missing. This matches anchor 3 (some relevant keywords, missing common variations/synonyms); it is above anchor 2 (only generic keywords) but below anchor 4's fuller keyword coverage.

3 / 5

Distinctiveness Conflict Risk

The cold-start framing ('a fresh agent in a new session can pick up any step without reading prior steps') carves out a niche, but 'turn an objective into a step-by-step plan' is a broad trigger surface that overlaps with generic planning/decomposition skills. This lands at anchor 3 (somewhat specific but could still overlap with similar skills) rather than 4, which requires only minor overlap risk with closely related skills.
