sharepoint-spreadsheet-formula-builder

Design, repair, and roll out formulas in SharePoint-hosted workbooks with connector-aware retrieval, validation, and upload discipline. Use when the user wants to add a formula column, fix a broken formula, choose between a fill-down formula and a spill formula, build a lookup or filter formula, or reuse workbook logic safely.

Quality

Content

100%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A high-quality, well-structured body: a sequenced workflow with validation and error recovery, concrete parameterized connector calls, and a cleanly signaled one-level reference. The only minor gap is that executable Excel formula examples live in the reference rather than the body, which is acceptable for this instruction-oriented skill.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence, with no padding about what Excel or SharePoint is; its prose conveys non-obvious operational constraints (connector routing, Graph URL preference) rather than basic concepts Claude already knows.

3 / 3

Actionability

It gives concrete, parameterized tool calls (e.g. `search(query=None, hostname=...)`, `fetch(download_raw_file=true)`) and specific formula-selection rules; as an instruction-only skill, the absent in-body formula snippets are not penalized because the guidance is actionable.

3 / 3

Workflow Clarity

Nine clearly sequenced steps include explicit validation checkpoints (test a representative slice in step 6; re-fetch and verify target cells in step 9) plus an error-recovery feedback loop ("If a write fails with `itemNotFound`, re-check the root-relative path"), so it is not capped at 2.

3 / 3

Progressive Disclosure

The body is an overview that points twice and clearly to one real, one-level reference (`./references/formula-patterns.md`, verified to exist with no nested references), with formula patterns appropriately split out of the main file.

Description

100%Weight 40%Scale 1-3

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, well-scoped description: concrete actions, natural trigger phrasings, an explicit Use-when clause, and a distinct SharePoint-workbook niche. Voice and trigger coverage meet the top anchor on every dimension.

DimensionReasoningScore

Specificity

"Design, repair, and roll out formulas in SharePoint-hosted workbooks" lists three concrete verbs with modifiers, matching the anchor for multiple specific concrete actions rather than only naming a domain.

3 / 3

Completeness

It explicitly answers what ("Design, repair, and roll out formulas…") and when via a clear "Use when the user wants to…" clause; voice is imperative/third person with no first/second-person penalty, so it is not capped at 2.

3 / 3

Trigger Term Quality

Phrases like "add a formula column," "fix a broken formula," "choose between a fill-down formula and a spill formula," and "build a lookup or filter formula" are natural terms a user would actually say, giving good coverage rather than only some variations.

3 / 3

Distinctiveness Conflict Risk

The niche is tightly scoped to SharePoint-hosted workbooks via the connector with formula-specific triggers, making it clearly distinguishable and unlikely to fire for unrelated skills.
