Conciseness

The body is lean and assumes competence — terse flag docs ("--top/-k: number of results"), mode table ("name: filename-only (fastest)"), and no explanation of concepts Claude already knows. Held at 4 rather than 5 by minor redundancy: "Use `vexor` first for intent-based file discovery" restates the Goal section, and "(exclude rules apply on top)" repeats the Common Flags section.

Actionability

Provides a concrete synopsis with defaults, flag reference, and four copy-paste-ready examples ("vexor search \"config loader\" --path . --mode code --ext .py"). Not 5 because the Command section shows "vexor \"<QUERY>\"" while every example invokes "vexor search", and "(tell the user to set up)" is vague about what to set up; well above 3 since all examples are executable rather than pseudocode.

Workflow Clarity

A simple single-action skill with an unambiguous primary command, a clear fallback ("If `vexor` is missing, follow references/install-vexor.md"), and a Troubleshooting section mapping problems to remedies ("Need ignored or hidden files: add `--include-hidden`"). Not 5 because the `vexor` vs `vexor search` invocation discrepancy leaves the exact command form ambiguous and first-run indexing has no explicit retry guidance.

Progressive Disclosure

The body itself is well-sectioned with content appropriately kept inline for a single-command CLI tool, and the sole external pointer is clearly signaled ("follow references/install-vexor.md") — but that file does not exist in the bundle (no references/ directory), making the installation fallback a dead end. Structure is far better than a 2, but a broken sole reference is more than the "minor organization gaps" of a 4.

Specificity

States one concrete capability — "Semantic file discovery via `vexor`" — with the application framed as "locating where something is implemented/loaded/defined". This matches anchor 3 ("names domain and 1-2 concrete actions, but not comprehensive") rather than anchor 4, which expects several distinct listed actions; it omits capabilities like mode-based filtering or doc searching that the skill covers.

Completeness

Explicitly answers both parts: what — "Semantic file discovery via `vexor`"; when — "Use whenever locating where something is implemented/loaded/defined in a medium or large repo, or when the file location is unclear", with concrete trigger phrases plus a precedence directive ("Prefer this over manual browsing"). The 'when' is as explicit as anchor 5 requires, so not 4.

Trigger Term Quality

"locating where something is implemented/loaded/defined", "file location is unclear", and "medium or large repo" mirror natural user phrasing like "where is the config loaded?". Not 5 because common variations users would actually say — "search the codebase", "find where", "code search" — are absent.

Distinctiveness Conflict Risk

The "semantic" qualifier and named tool carve a clear niche distinct from plain text-search skills, with "Prefer this over manual browsing" explicitly claiming the niche. Minor overlap risk remains with generic find/grep-style code-search skills, so it fits anchor 4 rather than a 5 with "minimal conflict risk".
