running-sbx-sandboxes

Run and operate Docker Sandboxes — choosing an agent, passing it flags, git workspace modes, ports, secrets, network policy, and sharing host skills into a sandbox. Use when starting or re-attaching to a sandbox, picking between the built-in agents, signing in from CI, copying files in or out, or reaching for the right sbx command.

Quality

Content

92%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 a well-organized operating reference: executable commands, explicit recovery loops, and clean progressive disclosure to verified reference files and sibling skills. It assumes Claude's intelligence and avoids padding. The only minor gap is a handful of editorializing phrases that slightly reduce token efficiency.

DimensionReasoningScore

Conciseness

The body is dense and assumes Claude's competence (no primers on Docker, microVMs, or git), but carries a few light editorializing phrases such as "the most misunderstood thing in the CLI" that could be trimmed for a fully lean pass.

4 / 5

Actionability

Copy-paste-ready commands throughout, plus concrete worked rules — the `--` append-vs-replace argument rule, the `localhost` address-family trap, and `0.0.0.0`/`[::]` binding requirement — covering the common cases directly.

5 / 5

Workflow Clarity

Explicit feedback loop ("sbx policy log → allow network <host> → retry"), an ordered diagnose ladder (diagnose → daemon restart → reset), and create-time-only caveats with recovery actions provide clear sequencing and validation checkpoints.

5 / 5

Progressive Disclosure

The body is an overview that routes depth to one-level-deep real references (references/credentials.md, references/discrepancies.md) and to named sibling skills, with a "Where the detail lives" table for easy 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 comprehensive and well-structured, pairing a concrete capability list with explicit, natural "Use when" triggers and clear scoping against sibling skills. It reads in third person and avoids fluff or over-claims. Only minor trigger-term synonym coverage keeps it from a perfect mark on that single dimension.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities — "choosing an agent, passing it flags, git workspace modes, ports, secrets, network policy, and sharing host skills into a sandbox" — giving comprehensive coverage of the operating surface rather than vague abstraction.

5 / 5

Completeness

Explicitly answers both what ("Run and operate Docker Sandboxes …") and when ("Use when starting or re-attaching … picking between the built-in agents, signing in from CI, copying files in or out, or reaching for the right sbx command") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Natural trigger phrases like "starting or re-attaching to a sandbox", "signing in from CI", and "copying files in or out" map well to what a user would say, though a few common synonyms or CLI-name variants are not enumerated.

4 / 5

Distinctiveness Conflict Risk

Carves a clear niche (running/operating sbx sandboxes) and explicitly excludes generic Docker/Compose questions, with sibling-skill boundaries making wrong-skill triggering unlikely.
