Conciseness

Ten lean imperative bullets with zero padding — "Run `bun dev:info --json` before accessing local apps. Use the returned app URLs; never assume a port" — and no explanation of concepts Claude already knows. Every token earns its place; nothing could be cut without losing information.

Actionability

Mostly concrete and executable: named commands (`bun dev:info --json`), named files (`.env.worktree.local`, `.env.local`, `.worktree-env.json`), and exact template syntax (`{apps.<name>.url}`). Gaps keep it below 5: "Keep app offsets unique and below the configured range stride" and "Declare every variable an app needs under its `exports`" never say where these fields live, and no example `.worktree-env.json` is shown.

Workflow Clarity

The steps are present but ordered thematically rather than by execution — usage rules ("Run `bun dev:info --json` before accessing") precede the config setup (slot variable, `exports`, templates) that must actually come first, so the sequence is implicit. The sole checkpoint is the dev:info pre-access rule; there is no error-recovery guidance (e.g., what to do on a port conflict or unassigned slot), matching anchor 3 rather than anchor 4's "most checkpoints present".

Progressive Disclosure

Implementation is appropriately split out (the resolver and wrapper do live in `scripts/`), but the pointer "The generic resolver and command wrapper are bundled in `scripts/`" names no files or their roles, and `assets/worktree-env.schema.json` — which documents the `exports`, offsets, and range-stride fields half the bullets rely on — is never referenced at all. References are present but weakly signaled with a real navigation gap, matching anchor 3; it is not anchor 4 because the omissions exceed minor organization gaps.

Specificity

Concrete actions are explicit and precisely worded — "Discover and use stable per-app ports assigned to a local monorepo worktree" — but only two capability verbs are stated, leaving minor coverage gaps (config authoring, template resolution) versus the comprehensive multi-action anchor. It sits between anchor 3 (1-2 actions, not comprehensive) and anchor 4 (several actions, minor gaps), noticeably above the midpoint due to the precise domain wording.

Completeness

Explicitly answers both: what ("Discover and use stable per-app ports assigned to a local monorepo worktree") and when ("Use when starting, opening, testing, or debugging local apps, or when worktree slots, localhost ports, PORT, app URLs, or .worktree-env.json are involved") with concrete trigger phrases — a direct match to the anchor-5 example structure.

Trigger Term Quality

Comprehensive natural terms including synonyms and exact identifiers: "starting, opening, testing, or debugging local apps", "localhost ports", "PORT", "app URLs", and the config file name ".worktree-env.json". These are exactly the phrases a user would say when needing this skill, matching the anchor-5 example's synonym-plus-extension coverage.

Distinctiveness Conflict Risk

Clear niche (per-worktree port assignment in a local monorepo) with distinct triggers such as "worktree slots" and ".worktree-env.json" that no generic skill would claim, giving minimal conflict risk. It is not score 4 because there is no closely related skill with which these triggers could plausibly overlap.
