decomposition-planning-roadmap

Creates step-by-step decomposition plans and migration roadmaps for breaking apart monolithic applications. Use when asking "what order should I extract services?", "plan my migration", "create a decomposition roadmap", "prioritize what to split", "monolith to microservices strategy", or tracking decomposition progress. Do NOT use for domain analysis (use domain-analysis) or component sizing (use component-identification-sizing).

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 content delivers a concrete, usable decomposition-planning methodology with templates and a prioritization formula, but it is held back by redundancy across sections and a monolithic structure that inlines material better suited to reference files. Tightening the repetitions and splitting out the template/pattern catalog would meaningfully improve it.

Suggestions

Dedupe the six-pattern sequence: it appears in 'Core Concepts', 'Analysis Process Phase 1', and the 'Output Format' examples — keep one canonical list and reference it.

Move the output-format templates (roadmap, prioritized work plan, architecture stories, progress dashboard) and the pattern catalog into files under references/ and link to them from SKILL.md to improve progressive disclosure.

Trim the Best Practices Do's/Don'ts, Notes, and Next Steps sections, which restate guidance already covered in the phased process and prioritization factors.

DimensionReasoningScore

Conciseness

The body is structured and domain-specific rather than explaining basics, but the six-pattern sequence and process steps are restated multiple times, and the Do's/Don'ts, Notes, and Next Steps sections restate prior content, so it could be tightened.

3 / 5

Actionability

Provides concrete, copy-paste-ready artifacts — the priority formula 'Priority = (Value × 3) - (Risk × 2) - (Dependencies × 1)', a story template, and full markdown output templates — with only minor gaps where steps remain abstract questions.

4 / 5

Workflow Clarity

The six analysis phases are clearly sequenced with a defined output per phase and a closing Analysis Checklist, yielding most checkpoints; this is a planning skill rather than a destructive/batch operation, so the strict validation cap does not apply, though inline checkpoints are sparse.

4 / 5

Progressive Disclosure

The body uses clear section headers but is a single ~640-line monolithic file with no references or bundle files; the output-template catalog and pattern sequence are strong candidates for split-out reference files that are instead inlined.

Description

95%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 strong across all dimensions: it states concrete capabilities, supplies natural trigger phrases, answers both what and when, and explicitly disambiguates from sibling skills. It is a model of a well-written skill description.

DimensionReasoningScore

Specificity

Names several concrete actions — 'step-by-step decomposition plans', 'migration roadmaps', 'breaking apart monolithic applications', 'prioritize what to split' — with only minor coverage gaps relative to the comprehensive anchor.

4 / 5

Completeness

Explicitly answers both 'what' ('Creates step-by-step decomposition plans and migration roadmaps...') and 'when' ('Use when asking...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Extensive natural user phrasings are quoted verbatim ('plan my migration', 'create a decomposition roadmap', 'prioritize what to split', 'monolith to microservices strategy'), giving comprehensive trigger coverage including synonyms.

5 / 5

Distinctiveness Conflict Risk

Clear niche (decomposition planning) reinforced by an explicit negative boundary — 'Do NOT use for domain analysis (use domain-analysis) or component sizing (use component-identification-sizing)' — minimizing conflict risk.
