Conciseness

The body (~495 lines) contains no basic-concept padding, but includes several narrative digressions that could be tightened: the pre-fix Windows behavior anecdote ("before this seeding existed every launch handed Code OSS an empty shared dir"), the extended PLAYWRIGHT_CLI_SESSION env-var footnote, the "Why a helper script and not just docs" three-trap rationale, and the macOS Mach-ports caveat. This fits anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened'); it is well above anchor 2's generic padding but short of anchor 4's trimmable-to-near-lean state.

Actionability

Guidance is fully executable and copy-paste ready: complete bash and PowerShell launcher invocations with every flag, the JSON output contract with a worked example, a port-to-process-to-tool table, `node -p 'JSON.parse(...)'` capture snippets, and a concrete symptom-to-fix troubleshooting list. This matches anchor 5 ('copy-paste ready code or commands; specific examples cover the common cases') rather than anchor 4's 'minor gaps'.

Workflow Clarity

The multi-step flow is explicitly sequenced with validation checkpoints: launch blocks until CDP is ready and exits non-zero with a log tail on failure; "Inspect the launched window before proceeding" mandates visual screenshot verification before interacting; the missing sign-in flow defines explicit user choice points and a wait-for-exit step to avoid relaunch races; and the troubleshooting section provides error-recovery feedback loops. This matches anchor 5's 'explicit validation steps; feedback loops for error recovery'.

Progressive Disclosure

Sectioning is good and script references are one level deep and clearly signaled, but scoring against the actual bundle reveals that `playwrightScripts/focus-chat-input.ts` - referenced in the core focusing, pasting, and parallel-instance flows - does not exist in the bundle (only scripts/launch.sh, launch.ps1, monaco-paste.ts/sh, updateSettings.ts, waitForCdp.ts, bootstrap/, and cleanup/ are present). Additionally, deep reference material (Windows shared-storage internals, the full troubleshooting catalog) is inlined in a single ~500-line SKILL.md with no references/ split. The broken central reference and heavy inlining place this at anchor 3 rather than anchor 4's 'minor organization gaps'.

Specificity

Quotes like "Launch Code OSS (VS Code from sources) into an isolated throwaway profile with unique debug ports", "drive it with @playwright/cli", and "set breakpoints in the renderer / extension host / main process" list multiple concrete, comprehensive actions (anchor 5), but the second-person phrasing ("so you can drive it", "you want to interact") triggers the rubric's one-point specificity penalty. It is clearly above anchor 3's '1-2 concrete actions' level, so 4.

Completeness

The 'what' is explicit ("Launch Code OSS... into an isolated throwaway profile with unique debug ports so you can drive it with @playwright/cli AND attach a Node debugger via dap-cli") and the 'when' is explicit with concrete trigger phrases ("Use when working on VS Code itself and you want to interact with the running workbench, automate chat or UI flows..."). This directly matches the anchor-5 example pattern of both what and when with concrete triggers; anchor 4 would require a less explicit 'when'.

Trigger Term Quality

Natural phrases a user would actually say are well covered: "working on VS Code itself", "automate chat or UI flows", "test UI features", "take screenshots", "set breakpoints", "combine UI driving with debugging". A few natural synonyms are missing (e.g. Copilot, extension development, 'debug VS Code'), which matches anchor 4 rather than the comprehensive synonym-and-extension coverage of anchor 5.

Distinctiveness Conflict Risk

"VS Code from sources", "Code OSS", "@playwright/cli", "dap-cli", and "extension host" carve out a clear niche (developing/automating/debugging VS Code itself) that no generic skill would trigger for. Minimal conflict risk, matching anchor 5; it is not merely 'mostly distinct' as in anchor 4.
