add-managed-cli

Add or upgrade a curated, immutable managed CLI for Sim Function sandboxes, including client-safe catalog metadata, a pinned server-only installation recipe, checksum and executable verification, provider compatibility, PATH propagation, content-addressed image identity, and tests. Use when adding a CLI to the Sandbox managed-CLI selector or changing an existing managed CLI version or recipe.

Quality

Content

88%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 content is highly actionable and well-sequenced with strong validation checkpoints, and it assumes Claude's intelligence without padding. It loses points only for minor rationale prose and the absence of any progressive-disclosure file split despite its length.

DimensionReasoningScore

Conciseness

The body is largely lean and assumes Claude's competence — it never explains what a CLI, checksum, or sandbox is — but several prose passages in 'Read First' and 'Preserve Generic Behavior' explain rationale that could be trimmed, keeping it just short of fully efficient.

4 / 5

Actionability

Concrete, executable guidance throughout: named files (cli-tools.ts, cli-tools.server.ts), named helpers (defineBinaryRecipe, defineTarGzipRecipe), exact required fields (sha256, artifactUrl), and copy-paste validation commands covering the common addition case.

5 / 5

Workflow Clarity

A clear numbered sequence (sections 1–6) with explicit validation checkpoints ('Required Validation' commands and a 'Completion Checklist'), satisfying the feedback-loop requirement for batch/supply-chain operations rather than capping at 3.

5 / 5

Progressive Disclosure

Well-organized into clearly signaled sections with no nested references, but all content is inlined in a ~145-line SKILL.md with no bundle files; some detail (the full recipe contract or the long validation command block) could be split into a one-level-deep reference file to reach fully clear navigation.

Description

92%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 specific, complete, and distinctive, with explicit what-and-when guidance in third person. Its only weakness is trigger phrasing that relies on domain-specific jargon rather than natural synonyms a user would casually say.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'client-safe catalog metadata', 'pinned server-only installation recipe', 'checksum and executable verification', 'PATH propagation', 'content-addressed image identity, and tests' — giving comprehensive coverage of what the skill does.

5 / 5

Completeness

Explicitly answers both 'what' (the enumerated catalog/recipe/verification activities) and 'when' via a concrete 'Use when adding a CLI to the Sandbox managed-CLI selector or changing an existing managed CLI version or recipe' clause.

5 / 5

Trigger Term Quality

Natural triggers like 'adding a CLI to the Sandbox managed-CLI selector' and 'changing an existing managed CLI version or recipe' are present, but the phrasing leans on domain jargon ('Sim Function sandboxes') and lacks common synonyms or variations a user might say. It is above the midpoint because the triggers are actionable, but not a 5 due to the specialized vocabulary and missing everyday synonyms.

4 / 5

Distinctiveness Conflict Risk

A clear niche — managed CLI selection for Sim Function sandboxes — with distinct triggers tied to a specific selector and version/recipe changes, minimizing overlap with other skills.
