What it does

Data Table Manager is an agent skill from n8n-io/n8n, published by the product's own GitHub organization. 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).

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/data-table-playbook.md`).

It sits in Documents & Office, covering Workflow automation, Excel spreadsheets and CSV and tabular files. It works with n8n, Microsoft Excel and Model Context Protocol. The repository describes itself as: Fair-code workflow automation platform with native AI capabilities. Combine visual building with custom code, self-host or cloud, 400+ integrations.

When your agent uses it

  • Natural standalone requests like what data tables do I have?
  • Show/list my tables
  • What columns are in this table?
  • Whenever the user asks to list

Example prompts

  • “what data tables do I have?”
  • “show/list my tables”
  • “what columns are in this table?”
  • “/data-table-manager”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Classify the job: inspect, design/create, import, seed, query, schema
  2. Resolve the target first. Call data-tables(action="list") before creating
  3. Use table IDs after discovery. Include projectId whenever list results or
  4. Inspect schema before writes, deletes, column changes, imports into an
  5. Execute the smallest direct tool sequence. Prefer read -> decide -> write;
  6. Close with facts: table name, table ID when available, project if relevant,

What it can do on your machine

Read from SKILL.md and the folder at commit 60ad29f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Data Table Manager loads about 2.3k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 132 tokens; SKILL.md has 1,263 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~132
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,263 words (~2,300 tokens).

“For workflow builds that create or write Data Tables, load this skill, then workflow-builder, before build-workflow.”
