Conciseness

Lean and dense with non-obvious guidance: 'A proposal that pairs tools ("Bitbucket + Jira") is one option; a tool that only replaces part of the stack ("Dagger") is judged on that part.' No padding and no explanations of concepts Claude already knows; every token earns its place.

Actionability

Concrete, specific guidance throughout: a fixed output contract of seven ordered sections, a table spec ('one row per capability that matters to the goal, one column per option'), enumerated option categories, and evidence rules ('Check vendor claims... against the vendor's own pages, dated today'). Minor gaps keep it below anchor 5: no example output and no concrete method for measuring one-off vs recurring effort.

Workflow Clarity

A clear sequence — goal → options → facts → output sections in order → weighing rules — with an implicit checkpoint ('Mark anything unverified as such'). It is a read-only analysis, so the destructive/batch validation cap does not apply, but there is no explicit pre-verdict verification step, keeping it at anchor 4 rather than 5.

Progressive Disclosure

Under 50 lines, single-purpose, no bundle files and no content that belongs in separate references; sections are well-organized with clear headers. Per the guideline, a skill under 50 lines with no need for external references scores 5 with well-organized sections alone.

Specificity

Names the domain ('a change of tool, platform, vendor, service or architecture') and the action family 'evaluate, compare or weigh', but these are near-synonyms rather than several distinct concrete actions, and no outputs (comparison table, verdict, costs) are stated. Fits anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive') better than 4, which requires a list of several specific actions.

Completeness

The 'when' is explicit with concrete trigger phrases ('Use when asked to evaluate...'), but the 'what' is only embedded in that trigger clause — there is no independent statement of capabilities or outputs. Clearly above anchor 4's midpoint but short of anchor 5, which requires both answered explicitly and separately.

Trigger Term Quality

Quotes the literal phrases users naturally say: "should we move to X", "evaluate X vs Y", "is X worth it", "I'm hearing good things about X", alongside evaluate/compare/weigh synonyms. Comprehensive natural-term coverage matching the anchor-5 example's spirit.

Distinctiveness Conflict Risk

Clear niche — technology/vendor switch decisions — with distinctive conversational triggers ('should we move to X', 'is X worth it') that are unlikely to fire for research or generic analysis skills. Matches anchor 5: clear niche with distinct triggers, minimal conflict risk.
