Tie an LP statement to the fund's NAV pack — recompute the LP's capital account from the NAV components and flag any line that doesn't agree. Use before LP statements are distributed.

Quality

Content

92%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 tight, well-structured instruction-only skill: an exact recomputation formula, an explicit comparison tolerance, a checklist of cross-checks, and a defined output contract, all with zero padding. The only refinement available is naming the specific nav MCP operations and how crystallization is detected, which would lift actionability to fully executable.

DimensionReasoningScore

Conciseness

The ~30-line body is lean and assumes domain competence: no padding, no explanation of concepts Claude already knows (the blockquote "The generated statement is the thing under test" is one line of orientation, not fluff). Every section — formula, comparison rules, checks, output — earns its tokens.

5 / 5

Actionability

The arithmetic block gives a concrete recipe, the comparison step has an explicit tolerance ("Tolerance: `0.01`") and a worked flag example ("statement used 12.40% ownership, NAV pack shows 12.38% after the Q1 transfer"), and the output format is specified. Minor gaps keep it below 5: no specifics on which nav MCP operations retrieve the inputs, and how to detect carry crystallization ("if crystallized this period") is left undetermined.

4 / 5

Workflow Clarity

A clear sequence — recompute, compare line-by-line at an explicit tolerance, run the additional-checks checklist, produce the defined output — with an explicit safety boundary ("Do not edit the statement"). The skill is itself a read-only validation workflow, so the missing-feedback-loop cap for destructive/batch operations does not apply.

5 / 5

Progressive Disclosure

Under 50 lines, single task, no bundle files or external references needed; the four well-organized sections (Recompute, Compare, Additional checks, Output) satisfy the simple-skill exception.

Description

87%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 strong description: it names the domain, lists several concrete actions, includes an explicit and well-timed 'Use before...' trigger, and occupies a distinct niche. The only minor gap is a few missing natural synonyms (e.g., 'reconcile', 'tie-out').

DimensionReasoningScore

Specificity

"recompute the LP's capital account from the NAV components" and "flag any line that doesn't agree" name several concrete actions in the fund-administration domain. Below anchor 5 because coverage is not comprehensive (the cross-checks and reconciliation scope are not enumerated); above anchor 3 because more than 1-2 specific actions are listed.

4 / 5

Completeness

Both parts are explicit: the what ("recompute the LP's capital account from the NAV components and flag any line that doesn't agree") and the when ("Use before LP statements are distributed"). The when-clause is a concrete workflow trigger, not the generic phrasing of anchor 4.

5 / 5

Trigger Term Quality

"LP statement", "NAV pack", and "capital account" are the natural phrases a fund-admin user would say, and "Tie an LP statement to the fund's NAV pack" mirrors the natural verb "tie out". Below anchor 5 because common synonyms like "reconcile"/"tie-out" are missing; above anchor 3 because the core natural terms are all present.

4 / 5

Distinctiveness Conflict Risk

LP statement / NAV pack reconciliation is a highly niche domain with distinct trigger terms; there is minimal realistic overlap with any other skill.
