connecting-to-sbx-sandboxes

Point an external editor or app — VS Code, Cursor, Claude Desktop, or ChatGPT — at a running Docker Sandbox over SSH via the `<name>.sbx` hostname, so the tool's UI stays on the host while files and processes run inside the sandbox. Use when setting up `sbx setup ssh`, wiring a remote-SSH connection in one of those apps, hitting a stalled or looping connection, or deciding whether Claude Desktop's credential-isolation warning applies to a given setup.

Quality

Content

86%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.

A well-structured, expert-targeted reference with concrete commands, a practical troubleshooting table, and clear cross-skill navigation. The only real gaps are minor verbosity in dated/versioned sections and the absence of an explicit validation feedback loop.

Suggestions

Move version-gated date/version detail (0.37.0/0.37.1/0.38.0, 2026-07-29) into a short 'Version notes' or 'Deprecated behavior' section so the main flow stays concise.

Add an explicit validate→fix→retry loop for the SSH-config repair step (e.g. 'delete the managed block, re-run `sbx setup ssh`, then re-test `ssh <name>.sbx`; repeat if the duplicate block persists').

Tighten the 'Last verified' paragraph to one or two sentences, pushing the release-note audit guidance into a bullet rather than prose.

Dimension	Reasoning	Score
Conciseness	Lean and aimed at a competent reader with little concept re-explanation; a few explanatory paragraphs and the version/date-heavy "Last verified" section could be trimmed slightly, but nothing is severely padded.	4 / 5
Actionability	Fully executable guidance throughout — `sbx setup ssh`, `ssh demo.sbx`, `sbx create --name demo codex .`, a real VS Code setting string, and concrete per-app UI steps covering the common cases.	5 / 5
Workflow Clarity	A clear sequenced flow (confirm `ssh <name>.sbx` from a terminal first, then add the host in the app) with a bug/symptom/workaround table and a verification step (`where.exe sh`), but no explicit validate→fix→retry feedback loop.	4 / 5
Progressive Disclosure	Single self-contained SKILL.md with well-organized section headers and one-level cross-links to sibling skills; no bundle files exist or are needed, so the in-skill structure cleanly satisfies the simple-skill case.	5 / 5

Description

95%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.

A strong, third-person description that clearly states the capability and gives concrete, natural trigger phrases covering setup, troubleshooting, and a credential caveat. Minor specificity gap is that it describes one core capability rather than a list of distinct actions.

Dimension	Reasoning	Score
Specificity	Names four concrete target apps and a specific action ("Point... at a running Docker Sandbox over SSH via the `<name>.sbx` hostname") plus the host-UI/sandbox-process split, but the action set is essentially one capability framed a few ways rather than multiple distinct operations.	4 / 5
Completeness	Explicitly answers both what (point an external editor at a sandbox over SSH via the `<name>.sbx` hostname) and when ("Use when setting up... wiring... hitting a stalled or looping connection, or deciding whether... the credential-isolation warning applies").	5 / 5
Trigger Term Quality	Covers natural trigger phrases users would say — "setting up `sbx setup ssh`", "wiring a remote-SSH connection", "stalled or looping connection", "credential-isolation warning" — alongside all four app names, giving comprehensive keyword coverage.	5 / 5
Distinctiveness Conflict Risk	A clear narrow niche (sbx SSH setup for four named apps) with trigger phrases unlikely to fire for unrelated skills; the body even disambiguates it from the sibling host-agent-forwarding skill.	5 / 5
