Quality

Content

67%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, highly actionable role specification whose output template, DoD examples, and flag taxonomy give Claude concrete instructions to execute. Its main weaknesses are token spend on persona flavor and a generic hallucination disclaimer, plus a couple of abstract instructions where a worked example would remove ambiguity.

Suggestions

Delete the generic 'AI agents may occasionally hallucinate...' limitation and the persona narration ('Systematic and calm. Never panics about scope.') — they consume tokens without adding executable guidance.

Drop the parenthetical expansion of DAG ('Directed Acyclic Graph') and similar explanations of concepts Claude already knows.

Add a brief worked example showing an input requirement fragment mapped to a critical path and two checklist rows, to make the abstract dependency-mapping steps fully concrete.

DimensionReasoningScore

Conciseness

The body is mostly tight and task-oriented, but spends tokens on concepts Claude already knows ('Build a DAG (Directed Acyclic Graph) mentally'), a generic hallucination disclaimer ('AI agents may occasionally hallucinate or provide incorrect guidance...'), and persona narration ('Systematic and calm. Never panics about scope.') that could be trimmed.

3 / 5

Actionability

Concrete, template-driven guidance throughout — hierarchical numbering example ('1.0 Auth System → 1.1 User model → 1.2 Password hash'), good-vs-bad DoD examples, specific flags ([LOW]/[MED]/[HIGH], [SEC], [EXT], [BLOCKED: REX]), and a full copy-paste ALEX PLAN output template. Falls short of 5 only because a few instructions stay abstract ('Build a DAG mentally') and no worked example of a critical path is given.

4 / 5

Workflow Clarity

The five numbered responsibilities give a clear sequence, and validation checkpoints are present — circular-dependency flags escalated 'immediately — do not guess', '[BLOCKED] items are resolved first' before handoff, binary DoD pass/fail, and an amendment process on re-invocation. Not 5 because there is no explicit final step verifying the plan's completeness against the Rex report before output.

4 / 5

Progressive Disclosure

No bundle files exist, and the ~120-line body is organized into well-labeled sections (When to Use, Responsibilities, Output Format, Handoff Protocol, Interaction Style, Limitations) with content appropriately inlined. It exceeds the under-50-lines simple-skill case, and the output template plus squad-context material could arguably live in a reference file, so it sits at good-structure rather than optimal.

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 states a clear, single-sentence 'what' but entirely omits 'when' to use it, and offers only one concrete action with limited trigger vocabulary. It is serviceable but reads as an under-specified trigger for a skill that governs a specific squad role.

Suggestions

Add an explicit trigger clause, e.g. 'Use when confirmed requirements need to be converted into ordered milestones, dependencies, and acceptance criteria.'

Enumerate the core capabilities — dependency mapping, hierarchical micro-task checklists, binary definitions of done, risk flags ([SEC]/[EXT]/[BLOCKED]), phased milestones — so specificity and trigger coverage improve.

Include natural synonyms users would say ('implementation plan', 'task breakdown', 'project plan', 'milestones', 'sprint planning') to broaden trigger-term coverage.

DimensionReasoningScore

Specificity

Names the domain and one concrete action — 'Turns requirements into a precise, dependency-aware implementation plan' — but lists no further capabilities, matching the 1-2-concrete-actions anchor rather than the several-actions level.

3 / 5

Completeness

The 'what' is clear (turns requirements into a dependency-aware implementation plan), but there is no 'Use when...' clause or any trigger guidance, which caps completeness at 3.

3 / 5

Trigger Term Quality

'requirements', 'implementation plan', and 'dependency-aware' are relevant natural keywords, but common variations users would say — 'planning', 'milestones', 'task breakdown', 'project plan' — are absent.

3 / 5

Distinctiveness Conflict Risk

The requirements-to-plan framing is somewhat specific, but broad planning territory means it could still overlap with general project-planning, architecture, or task-breakdown skills.
