Conciseness

Nearly all content is skill-specific operational knowledge Claude cannot know (CLI commands, resume semantics, working-file layout), but the core warning 'do not stop after plan new' is repeated three times — the STOP blockquote, the 'This is a loop' section, and the 'Concretely' paragraph — and the version-check preamble is similarly heavy. This matches anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened') rather than 4, where over-explanation would be only minor.

Actionability

Every instruction is copy-paste executable: exact commands with full JSON payloads ('spektacular plan new --data '{"name": "<spec_name>"}''', 'spektacular design ref list --data ...'), exact file paths (.spektacular/work/<plan_name>/<section>.md, .spektacular/tmp/), and precise placeholder conventions. This fully matches anchor 5 (fully executable, copy-paste ready commands covering the common cases).

Workflow Clarity

The workflow is explicitly sequenced (version check → spec selection → plan new → instruction/goto loop → walkthrough → finished) with genuine validation gates and feedback loops: the mandatory version check before anything else, the uncommitted-changes and auto_commit_failed question/error handling, the verification step over staged documents, broken design references that stop and report rather than plan around the gap, and the mandatory user sign-off before 'finished'. This matches anchor 5 (clear sequence with explicit validation steps and feedback loops for error recovery).

Progressive Disclosure

The body is well-structured with clear top-level sections (version check, tracing, what the skill does, file I/O, design refs, decisions, working files, how to start, orchestrator mode) and no nested or buried references — appropriate for a standalone skill with no bundle files. It does not reach anchor 5 because sections like the orchestrator-mode rules and the detailed resume procedure are inline content that could arguably live in a separate reference file, leaving minor organization gaps per anchor 4.

Specificity

The phrase 'Create a new Plan' names the domain (spec-to-plan planning) but describes only one minimal action; it never mentions the concrete artifacts the skill actually produces (plan.md, context.md, research.md) or the multi-step workflow it drives. This matches anchor 2 ('Names the domain but actions are minimal or generic') and is below anchor 3, which expects 1-2 concrete actions beyond the domain name.

Completeness

It clearly answers 'what' (create a plan from an approved spec) but the 'when' is entirely absent — there is no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It is not a 4 because the 'when' is not merely implicit-and-improvable; it is simply missing.

Trigger Term Quality

The only keywords are 'Plan' and 'Specification' — one or two generic terms with no natural phrases a user would say ('write an implementation plan', 'plan this spec', 'spektacular') and no synonyms or variations. It sits between anchor 2 ('one or two generic keywords; missing the natural phrases users say') and anchor 3, closer to 2 because even the terms present are abstract nouns rather than user-facing triggers.

Distinctiveness Conflict Risk

'Create a new Plan from an approved Specification' is somewhat specific (it implies a spec-driven pipeline) but 'plan' and 'spec' are generic words that would overlap with any general planning, roadmap, or spec-implementation skill. It does not reach anchor 4 because the description carries no distinctive trigger terms (e.g. 'spektacular', 'implementation plan') that would separate it from generic planning skills.
