At a glance

Audits a Dinobase source's existing annotations and fills only the gaps in table descriptions, column docs, PII flags and relationships through a subagent.

  • Works in 5 steps: Check the input schema → Audit existing annotations → Explore gaps → …
  • Documenting a newly loaded Dinobase source so agents can query it correctly
  • Calls uv and python3
  • Finding tables and columns that still lack descriptions or PII flags

What it does

Given a source name, this skill launches a general-purpose subagent with a detailed brief to audit what is already annotated and fill every gap without overwriting annotations that are already good. Step 0 prints the JSON input format that the dinobase annotate command accepts, and step 1 runs four checks with dinobase query against the metadata tables to find undocumented tables and columns.

For each gap the subagent reads the column list and a few sample rows to work out what entity or event the table represents, which columns carry business data rather than structural noise, which hold personal data such as email, name, phone, IP or user ID, and which are foreign keys. It also looks for relationships missing from the graph.

Writing happens in a single dinobase annotate call with a JSON array of only the missing items, mixing description, flag and relationship entries. A final step re-runs the checks to confirm no gaps remain. Commands run through uv, and the later part of the excerpt is truncated.

When your agent uses it

  • Documenting a newly loaded Dinobase source so agents can query it correctly
  • Finding tables and columns that still lack descriptions or PII flags
  • Topping up a partially annotated source without redoing finished work

Example prompts

  • “Index the semantic layer for the stripe source and only fill what's missing.”
  • “Audit the github source annotations and flag any columns that hold personal data.”
  • “Check which tables in the hubspot source still have no description and write them.”

Requirements

  • uv and the dinobase CLI
  • A Dinobase source with data already loaded

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Check the input schema
  2. Audit existing annotations
  3. Explore gaps
  4. Write only what's missing
  5. Verify completeness

What it can do on your machine

Read from SKILL.md and the folder at commit 2dd0636. 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

    Shell commands in SKILL.md call:

    • uv
    • python3

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

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    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

Dinobase Semantic Layer Indexing loads about 1.3k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 330 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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 330 words (~1,262 tokens).
