Conciseness

Mostly efficient and entirely product-specific (no padding with concepts Claude already knows), but several caveats are stated twice: the project-local-skill split appears in the intro ("It does **not** carry the in-project read/write contract") and again as a full section ("Working inside a project"), and the URL rule appears as "Get the URL from `preview_url` only — never hunt for it" and again as "Never construct or guess the URL — use the one `preview_url` returns". Anchor 3 ('could be tightened') fits better than anchor 4's 'minor instances'.

Actionability

Fully executable, copy-paste-ready commands cover the common paths: `npx @inkeep/open-knowledge init`, `npm install -g @inkeep/open-knowledge`, `ok start`, `ok cowork`, "call the **`preview_url` MCP tool** with `file` set to the absolute path", `ok open /abs/path/to/file.md`, `npx @inkeep/open-knowledge open /abs/path/to/file.md`, and precise `--project <dir>` flag semantics including failure behavior.

Workflow Clarity

Clear sequences: the sharing workflow is a numbered 3-step list, and the open-file workflow branches explicitly on "decide by the viewing surface you actually have", with error feedback such as "the command exits non-zero and says why" and "Read that line rather than assuming which project you got". Not anchor 5: there are no explicit validate-before-proceed checkpoints or retry loops, though the operations are non-destructive so the destructive cap does not apply.

Progressive Disclosure

Good structure with clear section headers and exemplary deferral — "This skill does not enumerate OK's capabilities ... read rather than guess" points to the docs and source URLs, and "Learn more" points to `ok --help`; the runtime contract is appropriately delegated to a separate skill. Not anchor 5: at ~147 lines with no bundle files, the full open-file decision logic is carried inline and the under-50-line simple-skill exception does not apply.

Specificity

The description enumerates concrete trigger scenarios — "wants to install it on a repository", "wants to open or preview a single markdown file that is not part of an OpenKnowledge project", "wants to share an OpenKnowledge project with collaborators", "asks how `ok init` / `ok cowork` / OK Desktop set up a project" — but these are user intents rather than the skill's own actions, which are never named (minor gap vs. anchor 5's 'comprehensive concrete actions').

Completeness

The 'when' is exhaustively explicit ("Read when the user asks ...", plus the negative trigger "Do NOT load to perform OpenKnowledge reads/writes"), but no explicit 'what' is stated — the skill's capabilities (explain, guide install/share/open) are only implied by the trigger clauses. That sits between anchor 2 ('only when present without what') and anchor 4 ('both what and when'), with the what weakly implied rather than clearly stated.

Trigger Term Quality

Good natural-phrase coverage: "what OpenKnowledge is", "install it on a repository", "open or preview a single markdown file", "share ... with collaborators", plus product terms `ok init`, `ok cowork`, OK Desktop. A few natural variations are missing (the "OK" abbreviation as a standalone term, ".md"/".mdx" extensions), keeping it below anchor 5.

Distinctiveness Conflict Risk

Clear niche with product-specific triggers (OpenKnowledge, `ok init`, `ok cowork`, OK Desktop) and an explicit exclusion clause ("Do NOT load to perform OpenKnowledge reads/writes — the runtime guidance ... ships as a separate project-local skill") that prevents overlap with the project-local runtime skill. Minimal conflict risk.
