Conciseness

The body is lean and section-driven, and its explanatory asides are protocol-specific knowledge Claude would not already have (Class 0/1/2/3 semantics, CROB operation codes 0x81/0x41/0x01, vendor index conventions) rather than padding. Minor trims are possible ('Quick test:', the multi-library name-drop 'pyOPENDNP3 / pydnp3 / dnp3-toolkit'), placing it at 'efficient with minor over-explanation' rather than the every-token-earns-its-place level.

Actionability

The nmap command and raw-socket probe are concrete, but the opendnp3 blocks elide essential setup ('# ... master init + asyncrun ...') making them non-executable as written, and the DNP3-SA downgrade section is comment-only with no runnable code. This matches the 'pseudocode instead of executable code; missing key details' anchor — not 4, because a significant fraction of the guidance cannot be copy-pasted or run.

Workflow Clarity

An implicit discover → read → control sequence exists with some pre-action checkpoints ('Always confirm point map (POINT.CSV or DNP3 device profile) before any write', simulator-first testing), but this is a destructive-operation skill with no post-operation verification or feedback loop (e.g., read-back of point state after SelectAndOperate). Per the rubric's cap for destructive workflows lacking validation steps, workflow clarity cannot exceed 3.

Progressive Disclosure

The body is well-organized into clearly signaled sections (Discover, Read attacks, Control attacks, Unsolicited reporting abuse, DNP3-SA downgrade, Tooling, OPSEC + safety) with no nested references and no bundle files, so everything is one level deep. It falls short of 5 only because ~120 lines of mixed material (vendor point-map table, SA-downgrade detail, external references) sits inline where a reference file would help; there is no explicit navigation to separate materials.

Specificity

The description lists multiple concrete, protocol-specific actions — "outstation enumeration", "binary input / analog input poll", "control relay output block (CROB) actuation", "unsolicited reporting abuse", "DNP3 Secure Authentication (DNP3-SA) downgrade" — with ports (TCP/20000, 19999) and object-level detail, matching the comprehensive-coverage anchor rather than the minor-gaps anchor at 4.

Completeness

The 'what' is explicit and detailed (enumeration, polling, CROB actuation, SA downgrade), but there is no 'Use when...' clause or equivalent trigger guidance in the description; 'when' is only weakly implied by the word 'attack'. Per the guideline, a missing explicit trigger clause caps completeness at 3 — not 4 because the 'when' is absent rather than merely imprecise.

Trigger Term Quality

Good keyword coverage including DNP3, outstation, CROB, analog/binary input, unsolicited, and DNP3-SA, but common natural variations a user would actually say — SCADA, RTU, substation, power grid — are missing from the description itself. This sits between 'some relevant keywords' (3) and 'comprehensive including synonyms' (5), closer to the former's completeness but with solid coverage, so 4.

Distinctiveness Conflict Risk

A clear niche (DNP3 protocol attacks) with highly distinct protocol-specific triggers (CROB, DNP3-SA, outstation, TCP/20000) that no other plausible skill would share, matching the minimal-conflict anchor. Not 4 because there is no meaningful overlap with related skills; the terms are unambiguous.
