Conciseness

The body avoids concept over-explanation (it never explains what Nx is) and is mostly command examples, but it has notable duplication: a second 'Listing Projects' section (lines 149-172) repeats the first, 'jq .targets | keys' appears four times (lines 61, 73, 211, 273), and ~80 lines of inline example JSON outputs pad the length. This matches anchor 3 ('mostly efficient but could be tightened') rather than 4 given the volume of repeated material, and not 2 since there is no padded conceptual prose.

Actionability

Fully executable, copy-paste-ready bash commands with jq recipes for every section, concrete example outputs, and an error-message-to-remedy troubleshooting section ('Cannot find configuration for task X:target' -> exact diagnostic commands). Specific examples cover the common cases, matching anchor 5.

Workflow Clarity

A read-only, query-driven reference skill (no destructive or batch operations, so the validation cap does not apply) organized by question/scenario with a troubleshooting section mapping failures to fixes. The duplicated 'Listing Projects'/'Project Details' sections blur navigation slightly and there is no ordering guidance, placing it at anchor 4 rather than 5's fully sequenced, checkpoint-rich structure.

Progressive Disclosure

The single bundle reference (references/AFFECTED.md) exists, is one level deep, and is clearly signaled from the body ('read the affected projects reference'). Structure is good, but the ~280-line body inlines large example-output blocks ('Programmatic Answers', ~80 lines of JSON samples) that are reference material and could be split out, matching anchor 4 rather than 5's appropriately split content.

Specificity

The core 'what' is generic ('Explore and understand Nx workspaces'), but the EXAMPLES clause explicitly enumerates several concrete capabilities: listing projects ('What projects are in this workspace?'), inspecting configuration ('How is project X configured?'), finding dependents ('What depends on library Y?'), target discovery, and failure debugging. This matches anchor 4 ('lists several specific actions; minor gaps') rather than 3, since coverage goes beyond 1-2 actions, and not 5, since the capability statements themselves are abstract verbs rather than concrete action lists.

Completeness

Both parts are explicit: what ('Explore and understand Nx workspaces... workspace structure, project configuration, available targets, and dependencies' implied via examples) and when ('USE WHEN answering questions about the workspace, projects, or tasks. ALSO USE WHEN an nx command fails or you need to check available targets/configuration before running a task'). The 'when' is multi-condition, explicit, and backed by concrete trigger phrases — a clear anchor 5 match, above anchor 4 where the 'when' would be less explicit.

Trigger Term Quality

Direct quotes of natural user phrasings ('What targets can I run?', 'Cannot find configuration for task', 'debug nx task failure') plus failure-triggered usage give strong, natural coverage. A few commonly said terms are missing ('monorepo', 'affected', 'dependencies', 'nx.json'/'project.json'), matching anchor 4 ('good keyword coverage; a few natural terms missing') rather than 5's comprehensive synonym/extension-level coverage.

Distinctiveness Conflict Risk

A clear Nx-specific niche with tool-locked triggers ('nx command fails', 'Cannot find configuration for task') that no other skill would claim; minimal conflict risk, matching anchor 5 ('clear niche with distinct triggers').
