Conciseness

The body is mostly lean (command tables, a compact error table, no concept over-explanation), but the Examples section re-presents commands already shown in Instructions, the "# 2025 = tax year" comment is repeated four times, and the IRS links duplicate references/implementation.md. This matches 'mostly efficient but could be tightened' rather than the padded 2 anchor or the trim 4 anchor.

Actionability

Every step is a copy-paste-ready executable command with concrete flags (--method fifo, --income-report, --format csv), full ${CLAUDE_SKILL_DIR} paths, and specific exchange export locations, covering the common cases (basic calc, method comparison, Form 8949, income, multi-exchange). Nothing is pseudocode or abstract, matching the 5 anchor.

Workflow Clarity

Steps 1–6 form a clear numbered sequence, but there are no in-flow validation or verification checkpoints — the Error Handling table is reactive documentation, not a checkpoint, and nothing tells Claude to verify CSV columns before calculating or sanity-check report totals. Because this is batch processing of financial data across many transactions, the rubric's cap for missing validation in batch operations applies, holding this at 3 despite the good sequencing.

Progressive Disclosure

The body is a well-organized overview with clearly signaled one-level-deep links to references/exchange_formats.md and references/implementation.md, both of which exist. However, references/errors.md and references/examples.md are never referenced while their subject matter (error handling, examples) is partially inlined in the body, an organization gap that keeps it below the 5 anchor.

Specificity

"Calculate cryptocurrency tax obligations with cost basis tracking, capital gains computation, and Form 8949 generation" names the domain plus several concrete actions, matching the 'several specific actions; minor gaps' anchor. It falls short of the 5 anchor because income-event handling (staking, airdrops, mining) — a documented capability of the skill — is not stated.

Completeness

The description explicitly answers 'what' ("Calculate cryptocurrency tax obligations with cost basis tracking, capital gains computation, and Form 8949 generation") and 'when' ("Use when calculating crypto taxes, generating tax reports, comparing cost basis methods, or identifying taxable events"), plus a concrete trigger-phrase list — matching the 5 anchor's structure exactly. Not below 4 because both elements are explicit, not merely present.

Trigger Term Quality

Triggers like "calculate crypto taxes", "generate tax report", "capital gains", "Form 8949", and "crypto taxable events" are natural phrases users would say, giving good coverage. A few natural variants are missing (e.g., "bitcoin taxes", "IRS crypto", "tax loss harvesting"), and "cost basis FIFO" is a slightly unnatural word order, so it does not reach the comprehensive 5 anchor.

Distinctiveness Conflict Risk

"Form 8949", "cost basis", and "crypto taxable events" carve out a clear crypto-tax niche with distinct triggers and minimal overlap risk against generic finance or document skills. The 4 anchor ('minor overlap risk with closely related skills') is a worse fit since no closely related trigger terms are shared.
