data-table-manager

Load before calling data-tables or parse-file. Use for natural standalone requests like "what data tables do I have?", "show/list my tables", or "what columns are in this table?", and whenever the user asks to list, show, create, inspect, import, seed, query, update, clean up, rename columns in, or delete data tables and rows, especially from CSV/XLSX/JSON attachments. Also load before building or planning workflows that create or write to Data Tables (then load workflow-builder before build-workflow).

Quality

Content

100%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 dense, well-structured operational skill: actionable tool calls and parameters, an explicit validation-gated procedure with recovery loops for destructive/batch operations, and a clean one-level reference split. No concept-padding and easy to navigate.

DimensionReasoningScore

Conciseness

Lean and directive throughout — no padding about what data tables or CSVs are; every line is actionable guidance or decision rationale that changes behavior (e.g. "Keep nested JSON out of normal columns", "Infer conservatively").

5 / 5

Actionability

Fully executable instruction-only guidance: concrete tool calls (data-tables(action="list"), parse-file with maxRows=20), specific filter operators (eq/neq/like/gt/...), batch limits (100 rows), safety limits (10 pages), and exact column-naming/type rules. Specific examples cover the common cases.

5 / 5

Workflow Clarity

A 6-step Default Procedure checklist with explicit validation checkpoints (inspect schema before writes/deletes, query matching rows first, show match count before broad mutations) and feedback loops (stop and report on admin block or denied approval) — meeting the destructive/batch bar rather than falling under the cap.

5 / 5

Progressive Disclosure

Clear overview with well-signaled one-level-deep reference: the body holds core operational guidance while "Use references/data-table-playbook.md for tool recipes, schema patterns, import edge cases, and output examples" points to the verified reference file with a contents description.

Description

100%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.

An exemplary description: domain-specific, packed with concrete actions and natural quoted triggers, explicitly covering both what and when, and actively managing overlap with workflow-builder. No verbosity, no fluff, no first/second-person voice.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions with comprehensive coverage: "list, show, create, inspect, import, seed, query, update, clean up, rename columns in, or delete data tables and rows" — eleven distinct operations, not vague language.

5 / 5

Completeness

Explicitly answers both what (build/maintain n8n Data Tables via the listed operations) and when ("Use for natural standalone requests like...", "whenever the user asks to...") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Quoted natural phrases users would actually say ("what data tables do I have?", "show/list my tables", "what columns are in this table?") plus file extensions (CSV/XLSX/JSON), giving comprehensive coverage including synonyms and extensions.

5 / 5

Distinctiveness Conflict Risk

Clear niche (n8n Data Tables) with explicit routing to avoid conflicts: "Load before calling data-tables or parse-file" and "then load workflow-builder before build-workflow," minimizing wrong-skill triggering.
