urdf

URDF robot description generation and default generation-time validation. Use when creating, editing, regenerating, inspecting, or debugging `.urdf` files, Python `gen_urdf()` sources, robot links, joints, limits, inertials, visual/collision geometry, mesh references, frame conventions, or generated robot-description artifacts. Use the SRDF skill for MoveIt2 semantic groups and IK/path-planning semantics; use the Replicator artifact review pane for project artifact paths; use the CAD skill for STEP/STL/3MF/DXF/GLB outputs.

Quality

Content

93%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A tight, actionable skill body with executable commands and a clear validated workflow, backed by a clean one-level reference structure. The only gap is that the error-recovery feedback loop lives in a reference rather than being summarized inline.

Suggestions

Add a brief inline feedback loop in the Workflow section (e.g. 'On validation failure: fix the generator source or design ledger, then regenerate the same explicit target — do not hand-edit the generated .urdf') so error recovery is visible without opening references/validation.md.

Surface the validation failure-handling steps from references/gen-urdf.md as a short checklist in the body, since URDF generation is a destructive/generated-artifact operation where the fix→regenerate loop matters most.

Make the validation checkpoint in step 6 an explicit gating condition (e.g. 'Only proceed to smoke testing once generation-time validation passes') to strengthen the checkpoint semantics.

Dimension	Reasoning	Score
Conciseness	The body is lean and assumes Claude's competence: it never explains what URDF/RViz/Gazebo are, and every section (Core Rules, Workflow, Commands, References) earns its place with operational content rather than concept padding.	5 / 5
Actionability	Provides copy-paste-ready executable commands covering the common cases (plain target, `-o` output override, `SOURCE.py=OUTPUT.urdf` multi-target pairs), plus a concrete numbered workflow and explicit file references.	5 / 5
Workflow Clarity	A clear 9-step sequence with an explicit validation checkpoint (step 6, fail-fast generation-time validation) and a reporting step (step 9), but the detailed fix-source-then-regenerate feedback loop is delegated to a reference rather than stated inline in the body.	4 / 5
Progressive Disclosure	SKILL.md is a well-organized overview with one-level-deep references signaled inline (e.g. 'See `references/design-ledger.md`') and enumerated in a References section; all six referenced files exist and the bulk detail is appropriately split out.	5 / 5

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that clearly states capability, gives concrete trigger terms with the file extension, and proactively disambiguates from neighboring skills. No vague fluff or over-claims.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions (generation, validation, creating/editing/regenerating/inspecting/debugging) across concrete URDF artifacts (links, joints, limits, inertials, visual/collision geometry, mesh references, frame conventions), giving comprehensive coverage rather than vague language.	5 / 5
Completeness	Explicitly states what it does ('URDF robot description generation and default generation-time validation') and when to use it ('Use when creating, editing, regenerating, inspecting, or debugging...'), satisfying both halves with concrete trigger phrases.	5 / 5
Trigger Term Quality	Covers natural domain terms a user would say (creating, editing, regenerating, inspecting, debugging `.urdf` files, robot links, joints, limits, mesh references) including the `.urdf` file extension and synonyms, matching the comprehensive-coverage anchor.	5 / 5
Distinctiveness Conflict Risk	Occupies a clear URDF niche and explicitly routes adjacent work elsewhere (SRDF for MoveIt2 semantics, Replicator for artifact paths, CAD for STEP/STL/3MF/DXF/GLB), minimizing conflict risk with sibling skills.	5 / 5
