The body is lean, assumes Claude's competence, and avoids explaining what .docx files or python-docx are; the only minor redundancy (the Basic vs run_shell blocks showing near-identical commands) is justified by demonstrating the tool-invocation syntax, so it holds at the 'lean and efficient' anchor.

It provides fully executable python one-liners for text, indexed paragraphs, tables, and headings, plus a prerequisite check and install command, matching the 'fully executable, copy-paste ready' anchor.

As a simple single-purpose read-only skill, its 5-step Example Workflow is clearly sequenced and includes a verification checkpoint (verifying python-docx availability); the destructive/batch cap does not apply since extraction is non-destructive, so it reaches anchor 3 under the simple-skills note.

There are no bundle files and no nested references; the single-task skill is organized into clearly signaled sections (When to Use, How to Use, Prerequisites, Tips, Example Workflow) with content appropriately inline, satisfying the 'well-organized sections, no external references needed' guidance.

It names a concrete domain and action ("Use run_shell with python-docx" "on .docx files") but describes essentially one fallback action rather than listing multiple specific concrete actions, so it sits at anchor 2 rather than 3.

It answers both 'what' (use run_shell with python-docx as fallback) and 'when' ("when read_file fails on .docx files") with explicit trigger guidance, so it is not capped at 2 and reaches the explicit-triggers anchor.

It includes relevant keywords ("read_file fails", ".docx files", "run_shell") but these are tool-centric; it misses natural user variations like "Word document" or "can't read this file", matching the 'some relevant keywords but missing common variations' anchor.

The niche is clear and narrow (.docx reading fallback when read_file fails), with distinct triggers unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor.
