Conciseness

The body is dense and actionable with no background-concept explanations and a tight host table, but Step 3's report-template section repeats its exactness demand multiple ways ('This is a fixed template, not a prompt for inspiration: reproduce it word for word. Do not paraphrase it, reorder its sentences, summarize it, translate it, or "improve" the wording — a correct install ends with these exact words'). Fits anchor 4's minor over-explanation better than anchor 3's broader slack or anchor 5's fully lean text.

Actionability

Every step ships an exact, resolvable command: 'pip install --upgrade memu-cli', 'uv tool install --upgrade memu-cli', 'memu-agent detect', '<your-binary> init --cloud-api-key <the user's memU key>', '<your-binary> docs install', and '<your-binary> retrieve "When did the user register for memU?"'. Placeholders are resolved by the host table, and common edge cases (uv-only machines, no API key, unknown host, stale build) are each handled concretely.

Workflow Clarity

A clearly sequenced three-step flow with explicit checkpoints and feedback loops: the Codex sandbox precheck, 'every part ends with a verify gate; do not proceed past a failing one', the stale-build recovery loop ('you are on a stale build: upgrade, then re-run the command that failed'), and the final retrieve verification. The destructive uninstall path routes through the same gated guide structure rather than proceeding unvalidated, so the destructive-operation cap does not apply.

Progressive Disclosure

A well-sectioned overview that defers detail exactly one level to the packaged '<your-binary> docs install' guide, which is clearly signaled and always in sync with the installed code. However, scoring against the actual bundle: 'scripts/db.py' and the 'assets/' images exist in the skill bundle but are never referenced or navigable from SKILL.md, an orphaned-content gap that fits anchor 4 rather than anchor 5's easy navigation.

Specificity

Lists several concrete actions ('identify your host, print its packaged guide, and follow it to wire (or unwire) both seams (record and inject)') spanning both install and uninstall, but the package-install, config, and verification steps are absent, and the second-person 'for whatever agent you are' costs one point under the voice guideline. It is above anchor 3 (more than 1-2 actions) but short of anchor 5's comprehensive coverage.

Completeness

Explicitly answers both questions: what ('Install or uninstall memU... identify your host, print its packaged guide, and follow it') and when ('Use when the user asks to install, set up, integrate, remove, or uninstall memU') with concrete trigger phrases, mirroring the anchor-5 example structure.

Trigger Term Quality

'Use when the user asks to install, set up, integrate, remove, or uninstall memU' gives comprehensive natural-verb coverage for both directions plus the product name as the trigger noun. This matches the anchor-5 example's synonym breadth; no natural phrasing a user would say is missing.

Distinctiveness Conflict Risk

The scope is a clear niche — memU install/uninstall for the executing host agent — and every trigger phrase names memU, so overlap with generic installer or memory skills is minimal. Fits anchor 5; anchor 4's 'minor overlap risk' would require a trigger that could fire for another skill, which is absent.
