What it does

Openfdd SQL Fdd is an agent skill from bbartling/open-fdd. Use when working on production DataFusion SQL FDD: sqlrules registry, central /api/fdd/run, parity with pandas oracle, no pandas in central. Triggers on: sqlrules, DataFusion, registry.yaml, FDD engine, SQL cookbook.

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Data & Analytics, covering SQL and DataFrames. It works with SQL and pandas. The repository describes itself as: Fault Detection Diagnostics (FDD) for HVAC datasets.

When your agent uses it

  • Working on production DataFusion SQL FDD: sqlrules registry
  • Central /api/fdd/run
  • Parity with pandas oracle
  • No pandas in central

Example prompts

  • “/openfdd-sql-fdd”

Workflow steps

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

  1. Never add silent pandas fallback in central.
  2. New production rules need SQL file + registry + cookbook + parity row.
  3. Pandas oracle may differ — document in parity/gap matrices; do not paper over.
  4. UI production path calls central REST — not local pandas runner for “real” FDD.
  5. Series overlay (/api/fdd/.../series) must honor Lab/session_config
  6. SCHED-1: portable occupancy — numeric/false unoccupied and string

What it can do on your machine

Read from SKILL.md and the folder at commit b5c4e9c. 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

Openfdd SQL Fdd loads about 514 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 162 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~514

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 162 words (~514 tokens).

“confirm_min and typed params the same way /api/fdd/run does (prefer session-tuned detail over a stale empty results index when overrides exist).”
