Conciseness

Steps 2–3 enumerate pattern/property pairs with 'Look for:' bullets (e.g., 'Look for: Multiple signals that should never be active simultaneously') that restate domain knowledge Claude already has and largely duplicate references/common_patterns.md, and Step 6 plus the Output Format section specify the same deliverables twice. It matches 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than level 2 because it never explains basic concepts (SVA syntax is correctly offloaded) and the conservative-inference and vacuity guidance genuinely earns its tokens.

Actionability

Provides a concrete SVA template ('assert property (...) else $error(...)'), an explicit output format skeleton, and a worked FIFO example, which is mostly executable guidance with minor gaps. Not level 5 because the FIFO example stops at prose ('No write when full', 'Count within bounds [0:DEPTH]') without showing the final generated assertion, and not level 3 because the templates and referenced pattern library are real SystemVerilog rather than pseudocode.

Workflow Clarity

The six steps (parse → invariants → liveness → map to properties → classify → generate) are clearly sequenced, with quality checkpoints present via guidelines ('Check vacuity: Suggest cover properties for antecedents', 'Be conservative', 'Mark confidence', and the bounded-liveness note). Not level 5 because there is no explicit validate-and-recover loop for the generated assertions (e.g., checking they compile or reclassifying a failing property), and not level 3 because those checkpoints, while not framed as feedback loops, are explicitly stated.

Progressive Disclosure

Both bundle files (references/common_patterns.md, references/sva_syntax.md) exist, are one level deep, and are well signaled — linked inline at the point of use in Step 4 and again in a dedicated References section with descriptions. Not level 5 because Steps 2–3 inline pattern/property detail that also lives in common_patterns.md, a minor organization gap that leaves some content duplicated rather than cleanly split.

Specificity

Lists multiple concrete actions — 'Automatically infer formal correctness properties', 'generate SystemVerilog Assertions (SVA)', 'Identifies control-flow invariants (mutual exclusion, valid-ready handshakes, pipeline ordering, safety properties), liveness expectations, and temporal properties' — with comprehensive coverage of the skill's capability surface, matching the anchor for multiple specific concrete actions without the minor gaps that define the level below.

Completeness

Explicitly answers both questions: the 'what' ('infer formal correctness properties... and generate SystemVerilog Assertions (SVA). Identifies control-flow invariants... liveness expectations, and temporal properties') and an explicit 'Use when...' clause with concrete trigger phrases, mirroring the anchor-5 example structure exactly; it is not the level below because the 'when' is already fully explicit and specific.

Trigger Term Quality

The 'Use when' clause supplies three complete natural user phrasings ('infer properties, generate assertions, or create formal specifications') plus synonyms (Verilog/SystemVerilog, properties/assertions/formal specifications, RTL/hardware designs), exceeding the coverage of the anchor-4 example; only trivial extensions like '.v'/'.sv' file extensions are absent, which does not drop it to 'a few natural terms missing'.

Distinctiveness Conflict Risk

The description is saturated with hardware-formal terminology (Verilog/SystemVerilog RTL, SVA, formal property generation, assertions) creating a clear niche with distinct triggers; 'adding assertions to existing RTL' and 'infer properties' would not naturally fire a general coding or document skill, so conflict risk is minimal rather than merely minor.
