Conciseness

Mostly efficient tool-specific content, but there is real tightening to do: the grant-policy rules appear twice (the dense "Operator grants" paragraph and again in "Don't"), the intro paragraph restates the description with promotional tone, and time-sensitive version details ("fixed in bridge 0.6.1") appear outside any known-issues section. Not 4 because the duplication and version-specific padding go beyond minor trim instances; not 2 because nearly all content is Alethia-specific knowledge Claude cannot already know.

Actionability

Fully executable throughout: exact tool invocations (alethia_tell({ instructions: ... })), copy-paste NLP example blocks, a complete MCP config JSON, eval expressions with expected return values ("32px", 320, 6), and npm commands. Common cases (smoke test, audit, safety proof, live demo) each get a concrete recipe.

Workflow Clarity

Multi-step flows are clearly sequenced with explicit validation: the dev feedback loop (write → navigate → eval → correct → repeat), "When smart assertions fail" with nearMatches/suggestedFix/pageContext as an explicit read-then-retry feedback loop, and the safety proof where "Any blocked:false row is a safety regression" defines the pass/fail checkpoint. The destructive-action workflow (expect block:) includes pass/fail criteria, so the validation cap for destructive operations does not apply.

Progressive Disclosure

The 230-line body is a single monolith with no bundle files at all: the bootstrap/troubleshooting section (~40 lines of npx-cache and transport-error remedies) and the NLP pattern/eval-example catalogs are reference material that clearly belongs in separate one-level-deep files. Sections are well-headered, which keeps it above 2, but the skill is far over the ~50-line threshold where inline-only organization would be acceptable; not 4 because substantial reference content is inlined rather than split.

Specificity

Lists several concrete actions — "interact with a real browser, run E2E checks, enforce safety policies, audit accessibility or security, and export signed evidence" — giving broad coverage, but the opening "patent-pending agent-native software runtime for executing and verifying application workflows" is marketing fluff rather than capability description. Not 5 due to the buzzword padding; not 3 because the action list goes well beyond 1-2 generic actions.

Completeness

Explicitly answers both what ("interact with a real browser, run E2E checks, enforce safety policies, audit accessibility or security, and export signed evidence") and when ("Trigger patterns include..." with concrete quoted phrases). This matches the anchor for clear what + when with concrete trigger phrases; the "Use when" guidance is present in equivalent, explicit form.

Trigger Term Quality

Natural trigger phrases are explicitly given — "test this page," "verify the login flow," "audit accessibility," "compliance audit," "run WCAG/NIST," "check that deletes are blocked" — phrases a user would plausibly say. Not 5 because common variations like "end-to-end test," "browser test," or "smoke test" are absent; not 3 because the listed phrases are genuinely natural rather than technical jargon.

Distinctiveness Conflict Risk

Names a specific product (Alethia, @vitronai/alethia MCP server) with a distinct niche — agent-driven browser testing with safety gates and signed evidence. Not 5 because somewhat generic triggers like "audit accessibility" and "compliance audit" could overlap with other audit/testing skills; not 3 because the named runtime and MCP-server requirement keep it mostly distinct.
