Conciseness

The single `packageId` parameter is documented three times (## Inputs bullet, ## Input table, ### Input JSON Schema) and the opening paragraph restates the frontmatter description nearly verbatim ('Note: Built-in packages... Note: Package removal may trigger a domain reload'). This is 'mostly efficient but includes some unnecessary explanation or could be tightened' (anchor 3) — not 2 because everything stated is factual and the body is short; not 4 because the duplication is genuine padding.

Actionability

Fully concrete CLI invocations are given (`unity-mcp-cli run-tool package-remove --input '...'`, `--input-file`, stdin heredoc) plus troubleshooting for a missing CLI and a real example value (`com.unity.textmeshpro`) in the input table. The primary command snippet uses the placeholder `"string_value"` rather than a real package ID, a minor gap that places it at anchor 4 rather than 5.

Workflow Clarity

The sequence is present (verify installed → call → result delivered after domain reload) and tool-side validation is described ('First verifies the package is installed via an offline `Client.List`... On removal failure, surfaces Unity's error message'), but this is a destructive operation with no caller-side verification step (e.g., re-running `package-list` to confirm removal after the reload). The implicit checkpoints match anchor 3, and the destructive-operation cap also limits the score to 3.

Progressive Disclosure

The body is under 50 lines, single-task, with no bundle files, cleanly organized sections, and its one external pointer ('Read the /unity-initial-setup skill') is clearly signaled and one level deep. Per the under-50-line guideline, well-organized sections alone justify anchor 5; there is no nested or buried referencing.

Specificity

Concrete actions with named artifacts are present — 'Uninstall a UPM package', 'Modifies `manifest.json`', 'may trigger a domain reload — the final result is delivered after the reload via the request's `requestId`'. This matches anchor 4 (several specific actions, minor gaps) rather than 5, since coverage is the mechanics of one operation rather than a comprehensive multi-action capability set.

Completeness

The 'what' is clearly and concretely answered, but there is no 'Use when...' or equivalent trigger clause — 'Use `package-list` to list installed packages first' is a related-tool pointer, not when-to-use guidance. Per the judging guideline, a missing explicit trigger clause caps completeness at 3 (clear 'what', 'when' missing).

Trigger Term Quality

Good natural keyword coverage — 'Uninstall', 'UPM package', 'Unity project', 'manifest.json' — but missing common synonyms users would say such as 'remove', 'delete', or 'Package Manager'. Anchor 4 (good coverage, a few natural terms missing) fits better than 3 (only 'some relevant keywords') and below 5 (no synonym/extension coverage).

Distinctiveness Conflict Risk

'UPM package', 'Unity project', and the built-in/dependency constraints carve a clear niche with distinct triggers, but there is minor overlap risk with closely related Unity package tools (package-add, package-install, package-list). Anchor 4 (mostly distinct, minor overlap with closely related skills) is the best fit.
