Conciseness

Lean throughout: "IEEE 754 double precision. No fixed-point, no decimal types." states decisions without explaining known concepts, and every section is dense rules plus minimal code with no padded or over-explained passages.

Actionability

All code is complete, executable Rust (prices_equal with epsilon/ulps margins, round_to_tick, validate_tick_alignment, the SymbolSpec impl, and three typed ingest functions), and the boundary table plus per-feed ingest examples cover the common cases copy-paste ready.

Workflow Clarity

The one multi-step flow is explicitly sequenced with a validation checkpoint and error direction ("round to tick, validate alignment (on failure return an error, never re-round), then format for the broker API"), and the symbol-table lifecycle and ingest boundaries are unambiguous. No destructive or batch operations, so no validation cap applies.

Progressive Disclosure

No bundle files exist and none are needed: the compact pattern content sits appropriately in a single well-sectioned file with clear headers, no monolithic reference material, and nothing buried. Navigation is trivial.

Specificity

Lists five concrete actions — "comparing, rounding, formatting, or parsing prices, or designing price types" — but stops short of naming the concrete artifacts the skill actually covers (tick size, market feeds, broker APIs), leaving minor gaps in coverage.

Completeness

Only the 'when' is present ("Load when comparing, rounding, formatting, or parsing prices, or designing price types") with no explicit statement of what the skill provides — structurally matching the "Use when working with documents" anchor. The 'what' (f64 price patterns, tick rounding, feed parsing) exists only in the separate summary field, not the description.

Trigger Term Quality

Natural phrases like "comparing", "rounding", "parsing prices", and "price types" are present, but common variations a user would say — "tick size", "price precision", "float comparison", "decimal" — are missing.

Distinctiveness Conflict Risk

"prices" and "price types" scope it to a clear niche, but the bare terms "rounding" and "formatting" could still trigger a generic number-formatting or float-comparison skill, so minor overlap risk with closely related skills remains.
