fleur-contract-data-dictionary

fleur-contract-data-dictionary is a skill for Claude Code, Codex from WackyGem/Fleur. It costs 89 tokens per session (2,013 once invoked), scanned A, original, MIT.

A data-dictionary workflow for maintaining field definitions and schemas across the Fleur data pipeline. A schema describes the fields, types, order, and missing-value rules that data follows between systems.

In plain words
What is it for?
Use it when changing pipeline contracts, Parquet schema boundaries, raw-field descriptions, Chinese field descriptions, or generated data dictionaries. It also guides updates to dbt metadata and the commands used to validate them.
Why use it?
It keeps source contracts, Parquet files, ClickHouse raw tables, and generated documentation consistent by identifying the correct source files to edit.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fleur-contract-data-dictionary scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Fleur Contract Data Dictionary

当任务涉及 pipeline/contractspipeline/contract_tools、scheduler Parquet schema 边界、docs/references/data_dict、dbt sources.yml 的 raw 字段事实、中文字段描述或生成物同步时,使用这个 skill。

核心边界

  • 字段事实源是 pipeline/contracts/datasets/*.yml,范围到 ClickHouse raw 层为止。
  • pipeline/contracts/glossary/tables.yml 只维护 raw table 描述,不维护字段或 canonical 字段名。
  • parquet.fieldssource -> S3 Parquet -> ClickHouse raw 的 Parquet 字段、类型、nullable 和顺序事实源。
  • docs/references/data_dict/*.mdpipeline/elt/models/sources.yml 是生成物,不作为字段事实源。
  • dbt canonical 字段治理入口是 pipeline/elt/metadata/field_glossary.yml
  • dbt staging.ymlstg_*.sql、stg 字段描述、tests 和 meta 由 pipeline/elt 项目维护,不写入数据契约。
  • 修改字段事实时先改 dataset contract,再运行生成器;不要手工修 generated data_dict 或 dbt sources.yml
  • 所有 Python、dbt、contract 命令在 pipeline/ 下通过 uv run 执行。
  • source 业务代码不直接解析 contract;contract 读取集中在 pipeline/contract_tools 和相关 adapter。
  • scheduler 允许 scheduler.defs.contract_schemasscheduler.defs.clickhouse.specs 作为 contract boundary 直接 import fleur_contracts
  • scheduler source business code 和 S3IOManager 不直接 import fleur_contracts;运行时只 import scheduler.defs.contract_schemas 暴露的 schema maps/constants。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fleur-contract-data-dictionary is a skill published in the GitHub repository WackyGem/Fleur (112 stars, last pushed 1mo ago), licensed MIT. It adds 89 tokens to every session and 2,013 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
