Quality

Content

82%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 well-structured, highly actionable ICS attack playbook with copy-paste-ready code, explicit safety gates, and clear phase sequencing. Its main gaps are minor: a little trimmable explanatory prose and the absence of explicit validate→fix→retry feedback loops for the destructive write/mode-change operations.

Suggestions

Add an explicit validate→fix→retry feedback loop after the Phase 4 write and Phase 5 mode-change steps (e.g., read back the tag to confirm the write took, and check PLC state after a mode change before proceeding).

Trim the introductory protocol primer and the 'Tag names are often self-describing' example list to tighten token efficiency, since Claude already knows ICS protocol basics.

DimensionReasoningScore

Conciseness

Mostly efficient — dominated by executable code and commands — but includes minor prose that could be trimmed, e.g. the introductory 'EtherNet/IP is the dominant North American ICS protocol…' paragraph and the 'Tag names are often self-describing' example list.

4 / 5

Actionability

Fully executable, copy-paste-ready guidance across all phases: nmap and cpppo CLI commands, pylogix tag enumeration/read/write snippets, and a cpppo CIP mode-change routine covering the common engagement cases.

5 / 5

Workflow Clarity

Phases 1–6 are clearly sequenced with safety gates ('SAFETY FIRST', Phase 4 'STOP' gate), read-back verification in ZFP, and a firmware patch check; minor feedback-loop gaps for write/mode-change operations keep it just below 5.

4 / 5

Progressive Disclosure

Well-organized into clearly headed phases and supporting sections (Common findings, Evidence, OPSEC, References); no bundle files exist so content is appropriately sectioned inline, though the monolithic CVE/evidence blocks could optionally be split out.

Description

82%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 highly specific, action-rich description that names concrete capabilities and rich trigger terms for a narrow ICS protocol niche. Its main weakness is the absence of an explicit 'Use when…' clause, which leaves the invocation trigger implicit and caps completeness.

Suggestions

Append an explicit 'Use when…' clause naming the natural trigger phrases (e.g., 'Use when the user mentions EtherNet/IP, CIP, port 44818/2222, Allen-Bradley/Rockwell PLCs, or pylogix tag enumeration').

Move or duplicate the comprehensive trigger keywords currently only in metadata.when_to_use into the description body so the invocation guidance is visible at the description level.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'List Identity broadcast, pylogix tag-database dump, tag read/write…, CIP Forward Open, PLC mode change (Stop/Run), and historical Rockwell auth-bypass CVEs' — with comprehensive coverage of the skill's capabilities.

5 / 5

Completeness

The 'what' is clear and detailed, but there is no explicit 'Use when…' trigger clause; per the rubric guideline, a missing explicit trigger guidance caps completeness at 3 even though the what-side is strong.

3 / 5

Trigger Term Quality

Comprehensive natural terms and synonyms a user would say — 'EtherNet/IP + CIP', 'TCP 44818 / UDP 2222', 'Allen-Bradley', 'Rockwell', 'ControlLogix/CompactLogix', 'pylogix', 'PLC' — including port numbers and vendor/product names.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (EtherNet/IP + CIP on Allen-Bradley PLCs, pinned to ports 44818/2222) with distinct triggers and minimal overlap risk with other skills.
