Conciseness

The body is dense, terse procedural prose that assumes competence — no basic-concept explanations, no library introductions, no padding. The 'Work Like a Painter' analogy section spends roughly fifteen lines on conceptual framing ('A painter does not finish one finger before sketching the hand') that could be trimmed to its operative rule, keeping it at 'efficient with minor instances of over-explanation' rather than 'every token earns its place'.

Actionability

Guidance is highly concrete and operational: exact state-file paths ('.slim/deepwork/<task-slug>/progress.md'), concrete setup commands ('ensure .gitignore contains .slim/deepwork/', 'mkdir -p .slim/deepwork'), hard limits ('at most about 40 lines', 'at most 15 lines'), and a copy-ready example ('Pass 2 gate — attempt 2 of 3'). Minor gaps keep it below fully-executable: no example layout of a progress.md body and the <session-id> derivation is never specified.

Workflow Clarity

The multi-phase process is explicitly sequenced (Planning a Pass → Running a Pass → Gate and Step Back with four numbered steps) with validation checkpoints throughout: 'Run the broad validation once on the reconciled state', acceptance via 'one decisive artifact', and explicit feedback loops ('After two misses from a lane, change the boundary or the specialist', 'at most two re-reviews, each only for materially changed risks'). Resume and completion flows are equally concrete.

Progressive Disclosure

Sections are well-organized and the skill is appropriately self-contained for process guidance, with no buried or nested references. It misses anchor 5 because at ~135 lines it exceeds the under-50-line simple-skill exception, and detail such as the state-file format contracts and setup/resume conventions could arguably live in a one-level-deep reference to keep the overview leaner.

Specificity

Names the domain ('orchestrator workflow for large, high-risk, multi-phase coding efforts') and concrete characteristics ('meaningful dependencies and review gates'), but lists no actual capabilities or actions. It characterizes scope rather than enumerating what the skill does, so it matches 'names domain and 1-2 concrete elements' rather than 'lists several specific actions'.

Completeness

The 'what' is clear ('High-cost orchestrator workflow for... coding efforts with meaningful dependencies and review gates') and the 'when' is present both positively ('for large, high-risk, multi-phase coding efforts') and via the explicit negative trigger 'Do not activate for routine multi-file changes', so the missing-'Use when' cap does not apply. It falls short of anchor 5 because the positive trigger lacks concrete 'use when...' phrasing.

Trigger Term Quality

Phrases like 'multi-phase coding efforts', 'review gates', and 'routine multi-file changes' are relevant but abstract; natural terms a user would actually say ('large refactor', 'migration', 'architecture overhaul', 'big project') are missing. Coverage exists but common variations and synonyms are absent.

Distinctiveness Conflict Risk

A clear niche (high-cost multi-phase orchestration) plus an explicit de-activation clause ('Do not activate for routine multi-file changes') keeps it mostly distinct. Not anchor 5 because subjective qualifiers like 'high-cost' and 'large' leave minor overlap risk with general planning or agent-orchestration skills.
