Conciseness

The body is two lines — a generator comment and "Load and follow the shared skill at `~/.agents/skills/cmux-workspace-status/SKILL.md`" — with zero padding and no explanation of anything Claude already knows. Every token earns its place, matching the anchor-5 example of lean, competence-assuming content.

Actionability

The single directive is concrete and executable as written (an exact path to load and follow), but the operational details — the actual `cmux workspace status set done` command and its conditions — live entirely in the external target with no inline summary or fallback. That minor gap keeps it below anchor 5's fully self-contained, copy-paste-ready guidance.

Workflow Clarity

Per the simple-skill guideline, this is a single task with one unambiguous action ("Load and follow the shared skill at <exact path>"). The operation is neither destructive nor batch, so no validation cap applies, and there is no multi-step sequence to leave implicit.

Progressive Disclosure

The body is a bare pointer with no overview content or sections, and its sole reference targets an absolute home-directory path outside the skill bundle (`~/.agents/skills/cmux-workspace-status/SKILL.md`) that does not resolve in this environment (the bundle has no references/, scripts/, or assets/). The reference is clearly signaled and only one level deep — above anchor 2 — but the absent overview and the unresolvable external dependency fall short of anchor 4's "good structure... minor organization gaps".

Specificity

"Pin the current cmux workspace to the done lane with `cmux workspace status set done`" names the skill's action with exact literal command syntax, which is far more concrete than anchor 3's generic two-action example. It stops short of anchor 5 because only one action is stated, not "multiple specific concrete actions".

Completeness

The what is explicit and concrete ("Pin the current cmux workspace to the done lane with `cmux workspace status set done`") and the when is fully explicit ("Use at the end of a work session running inside a cmux terminal, right before the final response; skip when work is blocked, handed off, awaiting user input, or when nothing was changed"), including negative skip conditions — a clear anchor-5 match that anchor 4's merely-present 'when' does not capture.

Trigger Term Quality

Natural terms for the niche are well covered: "cmux workspace", "done", "cmux terminal", "end of a work session", plus state terms like "blocked" and "handed off". It misses anchor 5 because common synonyms such as "mark complete", "finish", or "wrap up" are absent.

Distinctiveness Conflict Risk

The cmux workspace / done-lane niche, gated on "running inside a cmux terminal", is highly distinct with explicit triggers; virtually no other skill would collide with it, matching anchor 5's clear-niche description.
