Conciseness

The body is nearly all executable commands and assumes pnpm competence without explaining basics, but small padding exists ("It is crucial to keep those dependencies up to date") and the ACP example command is repeated verbatim in both the exact-commands block and the templated section. This matches anchor 4 (efficient, minor instances that could be trimmed) rather than anchor 5's "every token earns its place".

Actionability

Every command is copy-paste ready and covers each harness explicitly; the two templated commands use placeholders that are explicitly justified with worked examples, and the fx flow includes the exact curl command, the file to edit, and the test command. Fully executable guidance matching anchor 5.

Workflow Clarity

The sequence is clear (harness deps, bridge deps, pinned fx version, example alignment, SDK sweep, verification) with explicit validation: the verify script plus a feedback loop ("If this script shows errors, you must address them, then rerun the verification script until it passes") and fx tests after the version bump. Although this is a batch operation, validation is present, so the workflow-clarity cap at 3 does not apply; it matches anchor 5.

Progressive Disclosure

With no bundle files, all content is appropriately inline and organized into clear sections with good navigation. Minor organization gaps remain: "Update the pinned fx CLI version" and "Example dependencies" sit as #### subsections under "Update the harness dependency packages" despite being distinct tasks, slightly muddying the hierarchy — anchor 4 (good structure, minor gaps) rather than anchor 5.

Specificity

"Update the primary SDK dependencies of harness packages" names the domain and one concrete action but is not comprehensive — it does not enumerate the sub-capabilities (bridge deps, pinned CLI versions, example alignment, verification). It fits anchor 3: domain plus 1-2 concrete actions; it is not anchor 4 (no list of several specific actions) nor anchor 2 (the action is concrete, not generic).

Completeness

The description has a clear "what" ("Update the primary SDK dependencies of harness packages") and an explicit trigger clause ("Use when asked to update the harness SDKs or harness adapter dependencies") with concrete trigger phrases. Both what and when are explicitly answered, matching anchor 5 rather than anchor 4 (where the "when" would only be present but less explicit).

Trigger Term Quality

Trigger terms like "update the harness SDKs" and "harness adapter dependencies" are relevant and natural, but the description misses common variations and synonyms a user might say ("upgrade", "bump", "latest versions"). This matches anchor 3 (some relevant keywords, missing common variations) rather than anchor 4's broader coverage.

Distinctiveness Conflict Risk

The niche is highly specific to harness packages/adapter SDK dependencies — a domain few other skills would claim — and the triggers ("harness SDKs", "harness adapter dependencies") are distinct. Minimal conflict risk, matching anchor 5.
