Conciseness

The body is lean and assumes Claude's competence: every line is operational, with no explanations of known concepts, and it carries only non-obvious domain semantics such as "Empty `applies_when` means applicable in every situation except `exception`, not unknown" and the semantic-indexing caveat.

Actionability

Concrete guidance dominates: an executable SDK snippet, a complete JSON request body, and exact endpoints (POST /api/v1/rules/compile, GET /api/v1/tasks/{task_id}, GET /api/v1/content/read?uri=...&raw=true). Minor gaps: the SDK snippet assumes an already-constructed `client`, and polling/reading are named in prose rather than shown.

Workflow Clarity

Seven numbered steps with explicit checkpoints: poll only until terminal status, inspect `result.operations`/`written_uris`/`write_result`, and verify saved Rule/Scenario file layout, plus check-before-retry guidance in Boundaries. It falls short of the top anchor because no recovery path is specified when results are UNCERTAIN or REJECT.

Progressive Disclosure

Good structure with clear Goal/Workflow/Boundaries sections and mode-specific subsections, and no bundle files exist to reference. At ~95 lines, the dual-mode API detail (SDK vs HTTP parameter shapes) could be split into one-level-deep reference files to keep the overview leaner, a minor organization gap.

Specificity

"Compile durable constraints into OpenViking Rules with rules/compile" names the domain and one concrete action tied to a specific endpoint, but does not list several actions (verification, polling, reading are absent), matching the '1-2 concrete actions, not comprehensive' anchor rather than the 'several specific actions' level above.

Completeness

The description explicitly answers both what ("Compile durable constraints into OpenViking Rules with rules/compile") and when ("Use when the user asks to add rules or import a policy") with concrete trigger phrases, and adds explicit negative scope ("Do not use for preferences, facts, or rule search"), matching the top anchor.

Trigger Term Quality

"Use when the user asks to add rules or import a policy" provides two natural phrases, but misses common variations and synonyms such as "add a rule", "create rules", "compile rules", or "import policies", fitting the 'relevant keywords but missing common variations' anchor.

Distinctiveness Conflict Risk

The named niche system (OpenViking Rules, rules/compile) plus explicit exclusions of adjacent uses ("Do not use for preferences, facts, or rule search") gives a clear niche with distinct triggers and minimal conflict risk.
