openfdd-sql-fddA skill your agent uses when working on production DataFusion SQL FDD: sqlrules registry, central /api/fdd/run, parity with pandas oracle, no pandas in central.
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.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit b5c4e9c. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
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.
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.
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.
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).”

astronomer/agents
Queries the data warehouse with SQL and answers business questions about data.
flyrank-bih/flyrank-ml-internship-starter
Works with datasets far too big to download or load in pandas — SQL over remote Parquet with DuckDB, aggregate-then-model, iterate on samples.
vemetric/vemetric
A skill your agent uses when the user has tabular data (pandas DataFrame, parquet, csv, Arrow, json) and wants to filter, group, aggregate, join, or speed up slow pandas.
vemetric/vemetric
A skill your agent uses when the user wants to run SQL — especially analytical SQL — on local files (parquet/csv/json), URLs, S3 paths, or remote databases (Postgres, MySQL, MongoDB, ClickHouse…
apache/datafusion-python
A skill your agent uses when the user is writing datafusion-python (Apache DataFusion Python bindings) DataFrame or SQL code.
ancoleman/ai-design-components
Transform raw data into analytical assets using ETL/ELT patterns, SQL (dbt), Python (pandas/polars/PySpark), and orchestration (Airflow).

A skill your agent uses to evaluate architecture, design proposals, refactors, module boundaries, dependency direction, data flow, concurrency model, and maintainability tradeoffs across any codebase.
bbartling/open-fdd
A skill your agent uses for structured research on an unfamiliar or complex codebase before planning, reviewing, or editing.
bbartling/open-fdd
A skill your agent uses when implementation or review depends on external documentation, standards, protocols, APIs, SDKs, changelogs, or version-specific behavior.
bbartling/open-fdd
A skill your agent uses for rigorous pull request, branch, patch, or diff review.
bbartling/open-fdd
A skill your agent uses to design, run, or review performance work with reproducible A/B baselines.
bbartling/open-fdd
A skill your agent uses to compare any codebase against a specification, API contract, protocol, policy, RFC, security baseline, or product requirements document.

Run `npx skills add bbartling/open-fdd --skill openfdd-sql-fdd -a claude-code`. Or copy the skill folder (openfdd_agent_spec/skills/openfdd-sql-fdd in bbartling/open-fdd) into .claude/skills/openfdd-sql-fdd in your project. Claude Code loads it when a task matches its description.
Run `npx skills add bbartling/open-fdd --skill openfdd-sql-fdd -a codex`. Or copy the skill folder (openfdd_agent_spec/skills/openfdd-sql-fdd in bbartling/open-fdd) into .agents/skills/openfdd-sql-fdd in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add bbartling/open-fdd --skill openfdd-sql-fdd -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/openfdd-sql-fdd, .gemini/skills/openfdd-sql-fdd, .github/skills/openfdd-sql-fdd and .opencode/skills/openfdd-sql-fdd in your project.
SKILL.md names no scripts, command-line tools or credentials: Openfdd SQL Fdd is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Openfdd SQL Fdd has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 514 tokens (SKILL.md is roughly 2.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
