Conciseness

The body is lean and well-organized with no padding or explanation of basic concepts Claude already knows; every line carries operational guidance, matching the 'every token earns its place' anchor.

Actionability

Concrete, executable guidance is given throughout — exact tool and operation names (read/write/patch/patch_text), precise anchor syntax ('@@ existing line', '+new line', '-old'), and prefix rules. As an instruction-only skill, the absence of code is not penalized because the guidance is specific and actionable.

Workflow Clarity

The Editing Flow sequences steps clearly (read → patch → patch_text → edits) and includes a validation/retry feedback loop ('If freshness-aware line patching rejects an edit as stale, reread the file and retry'), plus a Failure Handling section. For a single-purpose skill this is unambiguous with explicit checkpoints.

Progressive Disclosure

The skill is under 50 lines with no external references needed, and content is organized into clear, well-labeled sections (Boundary, Access Modes, Editing Flow, Patch Text Rules, Failure Handling), which per the rubric guidance earns a 3 for simple skills with good organization.

Specificity

Lists multiple concrete actions ('reading, writing, and patching files') tied to a specific tool ('text_editor_remote'), matching the score-3 anchor for listing several specific concrete actions.

Completeness

Explicitly answers both what ('Guide safe use of text_editor_remote for reading, writing, and patching files on the connected A0 CLI host') and when ('Use when the user asks to inspect or edit files...'), with an explicit 'Use when' trigger. Score 2 is ruled out because the when clause is present and explicit, not implied.

Trigger Term Quality

Natural user phrasings are well covered: 'inspect or edit files', 'local files', 'on their computer', 'CLI host files', and 'not Docker/server files' — terms a user would naturally say. It is not the level below because coverage is broad rather than sparse.

Distinctiveness Conflict Risk

The niche is sharply bounded by 'connected A0 CLI host' and 'explicitly not Docker/server files', distinguishing it from server-side and Docker file tools, so it is unlikely to trigger for the wrong skill.
