This is a strong skill description that concisely covers specific actions (unpublish, remove dependencies, delete directory, clean topology, re-install), provides explicit trigger terms via a 'Use when' clause, and occupies a clear niche. It uses third person voice appropriately and avoids vague language or unnecessary verbosity.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: unpublish/delete from registry, remove dependencies, delete directory, clean topology references, re-install. These are detailed, actionable steps.	3 / 3
Completeness	Clearly answers both 'what' (fully delete a Tessl skill with specific steps) and 'when' (explicit 'Use when' clause with quoted trigger phrases).	3 / 3
Trigger Term Quality	Includes natural trigger terms users would actually say: 'delete skill', 'retire skill', 'remove skill', 'nuke skill'. These cover common variations of how a user would express wanting to fully remove a skill.	3 / 3
Distinctiveness Conflict Risk	Very specific niche: fully deleting/retiring a Tessl skill with registry and topology cleanup. The combination of 'Tessl skill' + 'delete/retire' + specific cleanup steps makes it highly distinct and unlikely to conflict with other skills.	3 / 3

Implementation

77%

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

This is a strong, well-structured skill with excellent actionability and workflow clarity. The step-by-step process is clearly sequenced with concrete commands, validation checkpoints, error recovery paths, and a comprehensive retirement checklist. Minor weaknesses include some redundancy between the HARD RULES, Notes, and Steps sections, and the file is somewhat long but not egregiously so.

Suggestions

Remove the 'Notes' section as its points are already covered by the HARD RULES and the steps themselves, reducing redundancy.

Dimension	Reasoning	Score
Conciseness	The content is mostly efficient but has some redundancy — the 'Notes' section repeats points already covered in the steps (e.g., 'Always confirm with user before deleting' is already a HARD RULE and Step 1). The 'Common issues' section adds useful but slightly verbose edge cases. Overall reasonably tight but could be tightened.	2 / 3
Actionability	Every step includes concrete, executable bash commands with specific file paths and tool invocations. The registry removal shows a clear fallback chain (unpublish → delete → archive). The retirement checklist provides copy-paste-ready verification commands.	3 / 3
Workflow Clarity	The 7-step workflow is clearly sequenced with logical ordering (check dependencies first, then registry, then local, then references). Explicit validation in Step 7 with verification commands, a comprehensive retirement checklist, and a dedicated error recovery section with feedback loops (unpublish fails → try delete → try archive) make this exemplary.	3 / 3
Progressive Disclosure	The content is well-structured with clear sections and headers, but it's a fairly long single file. The batch retirement, common issues, and error recovery sections could potentially be split into a separate reference file. However, for a skill of this complexity, keeping it in one file is defensible — it's just on the edge of being too much inline content.	2 / 3
