worktree-ports

Discover and use stable per-app ports assigned to a local monorepo worktree. Use when starting, opening, testing, or debugging local apps, or when worktree slots, localhost ports, PORT, app URLs, or .worktree-env.json are involved.

Quality

Content

80%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a tight, actionable rule set that trusts Claude's competence and correctly offloads the resolver implementation to bundled scripts. Its main gap is the absence of an explicit verification step before consuming a discovered port, which is the fragile point of this workflow.

Suggestions

Add an explicit validation checkpoint, e.g. after `bun dev:info --json`, verify the returned app URL/port is reachable or non-empty before using it (and retry if the slot env var is unset).

Include a one-line example of the `bun dev:info --json` output shape or a minimal `.worktree-env.json` snippet so the rules have a concrete referent.

Number the bullets (or split into 'Discover' / 'Configure' / 'Run' steps) so the implied sequence is an explicit workflow rather than an unordered list.

DimensionReasoningScore

Conciseness

A lean bulleted rule set with executable commands and no padding or explanation of concepts Claude already knows; every token earns its place.

5 / 5

Actionability

Concrete commands and files (bun dev:info --json, .env.worktree.local, .worktree-env.json, {apps.<name>.url}) are mostly executable, but no example of the .worktree-env.json shape or dev:info JSON output leaves a minor gap.

4 / 5

Workflow Clarity

The bullets imply a sensible order (run dev:info first, then start via root scripts, configure exports, cross-app templates) but lack any explicit validation checkpoint before using a returned URL or slot.

3 / 5

Progressive Disclosure

The under-50-line body is a clear overview with one well-signaled, one-level-deep reference to the bundled resolver/wrapper in scripts/ (verified to exist).

Description

90%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is concise, third-person, and pairs a concrete what-statement with comprehensive, file-anchored trigger terms. Its only weakness is a somewhat narrow action set, which is appropriate for this single-purpose skill but limits the specificity ceiling.

DimensionReasoningScore

Specificity

Names the domain and two concrete actions ("Discover and use stable per-app ports assigned to a local monorepo worktree"), but coverage is narrow rather than comprehensive.

3 / 5

Completeness

It explicitly answers both what (discover/use stable per-app ports) and when (concrete "Use when..." trigger phrases), matching the anchor for a clear dual answer with triggers.

5 / 5

Trigger Term Quality

"Use when starting, opening, testing, or debugging local apps, or when worktree slots, localhost ports, PORT, app URLs, or .worktree-env.json are involved" covers natural terms, synonyms, and the file extension comprehensively.

5 / 5

Distinctiveness Conflict Risk

A clear niche (per-app ports for monorepo worktrees) anchored by a file-specific trigger (.worktree-env.json) keeps conflict risk minimal.
