Conciseness

Dense and information-rich, assuming Claude's competence (no explaining Docker/systemd/DBs); avoids the concept-padding that defines the lower anchors, with only minor prose that could tighten, keeping it at the lean end.

Actionability

Provides fully executable code and commands — the TS owner-grant snippet, real SQL with actual columns, git inspection commands, and service-restart one-liners with concrete import paths — copy-paste ready rather than pseudocode.

Workflow Clarity

Clear Phase 0→4 sequence with explicit validation checkpoints (0b smoke test confirmed via AskUserQuestion, deferred-failure tracking, final verify step) and a feedback loop ('diagnose from logs and re-test — don't proceed') appropriate for risky role/config operations.

Progressive Disclosure

No bundle files exist, so disclosure is appropriately single-file; the body is well-organized into clearly navigable phase/section headers with single-level references (sibling skill /migrate-memory, repo source files) and no nested 2+-level reference chains.

Specificity

Lists multiple concrete actions — 'Seeds the owner, migrates legacy memory, reconciles container configs, and helps port custom v1 code' — matching the score-3 anchor for multiple specific concrete actions; not the vague single-domain language of a 2.

Completeness

States what it does (seeds owner, migrates memory, reconciles configs, ports code) and when to use it ('Run after `bash migrate-v2.sh` completes' plus the explicit trigger list), clearly answering both what and when with explicit triggers.

Trigger Term Quality

Explicit triggers 'migrate from v1', 'finish migration', 'v1 migration' are natural phrases a user would actually say, giving good coverage rather than the partial-keyword level of a 2.

Distinctiveness Conflict Risk

The NanoClaw v1→v2 migration niche with its specific triggers is a clear, narrow scope unlikely to fire for any other skill.
