78%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, lean instruction-only skill with a clear workflow, concrete chain template, and a properly signaled one-level-deep reference. Weakest in conciseness (recurring field lists) and actionability (no worked example), and lacks an explicit feedback loop despite implicit verification gates.
Suggestions
Dedupe the evidence-field list: define SPN, delegation mode, PAC/group data, encryption type, cache location, and accepting service once and reference it from Quick Start, Workflow, and What To Preserve instead of repeating it.
Add one worked example of a completed delegation chain (e.g. source principal -> RBCD edge -> S4U2self/S4U2proxy tickets -> target SPN -> accepting service -> resulting privilege) to make the template concrete and copy-paste ready.
Add an explicit feedback loop, e.g. 'if no service can be shown to accept the ticket, return to step 1 and re-identify the edge' so the verification gate has a defined retry path.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence (no padding about what Kerberos/TGTs are), but the evidence-field list (SPN, delegation mode, PAC/group data, encryption type, cache location, accepting service) recurs across Quick Start, Workflow, and What To Preserve, which could be tightened. | 4 / 5 |
Actionability | Provides a concrete reportable chain template ('principal -> delegation edge -> ticket type -> target SPN -> accepting service -> resulting privilege') and specific fields to record, but lacks a worked example of a completed chain to anchor the guidance. | 4 / 5 |
Workflow Clarity | A clear sequenced Quick Start plus a 3-phase workflow with verification gates ('Prove which service actually accepts the ticket', 'Separate candidate edges from the edge that really lands privilege'); this is an analysis skill so the destructive/batch validation cap does not apply, but no explicit validate-fix-retry loop is spelled out. | 4 / 5 |
Progressive Disclosure | SKILL.md is a concise overview with a single, clearly signaled one-level-deep reference ('Load `references/kerberos-delegation.md`...'), and that reference (verified present) appropriately splits the checklist, fields, edges, and pitfalls out of the main body. | 5 / 5 |
