Quality

Content

87%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.

The body is a lean, highly actionable command reference with strong progressive disclosure to a single deep reference file, but it lacks the validation checkpoints and feedback loops expected for destructive credential-extraction operations.

Suggestions

Add explicit validation/feedback-loop steps to each attack workflow (e.g., 'Verify the obtained NT hash works with psexec before proceeding to lateral movement; if auth fails, re-check the hash and domain SID').

Insert a checkpoint after offline cracking (e.g., 'Confirm cracked credentials are valid against the domain before pivoting') to satisfy the destructive/batch feedback-loop requirement.

DimensionReasoningScore

Conciseness

Lean and efficient with no padding or explanation of concepts Claude already knows — every line is an executable command, Cypher query, or reference table, and the brief technique descriptions are minimal and earn their place.

5 / 5

Actionability

Fully executable, copy-paste-ready commands across Impacket, Rubeus, Mimikatz, and Certipy with concrete flags, hashcat modes (13100/18200/19700), and credential usage examples covering the common attack cases.

5 / 5

Workflow Clarity

Per-technique sequences (collect → extract → crack; request → authenticate) are present, but this destructive/credential-extraction batch skill lacks explicit validation checkpoints or error-recovery feedback loops, which the rubric caps at 3.

3 / 5

Progressive Disclosure

A single real, one-level-deep reference (references/attack-paths.md) is clearly signaled in the Bundled Resources section with an explicit 'Read when ...' guidance, and content is appropriately split between the overview commands and the deep reference.

Description

75%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.

The description is specific and well-scoped to Active Directory exploitation with strong, distinctive technique keywords, but it omits an explicit 'when to use' trigger clause, leaving it incomplete per the rubric.

Suggestions

Add an explicit 'Use when ...' clause listing natural trigger phrases (e.g., 'Use when the user asks about kerberoasting, AS-REP roasting, DCSync, golden tickets, AD CS abuse, or BloodHound analysis in an authorized engagement').

Include synonym and file-extension-free natural variants (e.g., 'Kerberos ticket attacks', 'domain controller sync') to broaden trigger coverage to level 5.

DimensionReasoningScore

Specificity

Names multiple concrete attack techniques — 'BloodHound analysis, Kerberoasting, AS-REP Roasting, AD CS abuse, DCSync, Golden Ticket, Constrained Delegation' — giving comprehensive, specific coverage rather than vague language.

5 / 5

Completeness

The 'what' is clearly stated via the technique list, but there is no explicit 'when to use' clause in the description field itself, which the guideline caps at 3 despite trigger terms existing in metadata.when_to_use.

3 / 5

Trigger Term Quality

Strong natural technique keywords (Kerberoasting, DCSync, Golden Ticket, BloodHound) are present, but the description lacks 'Use when' trigger phrasing and synonym/extension coverage found in the level-5 anchor.

4 / 5

Distinctiveness Conflict Risk

A clear niche with distinct AD-exploitation trigger terms unlikely to collide with other skills; minimal conflict risk.
