fleur-dbt-model-readiness

fleur-dbt-model-readiness is a skill for Claude Code, Codex from WackyGem/Fleur. It costs 62 tokens per session (1,811 once invoked), scanned A, original, MIT.

A preparation guide for writing dbt staging models, which are cleaned and organized data tables built from raw inputs. It requires profiling the raw data before deciding on cleaning rules and tests.

In plain words
What is it for?
It is for inspecting raw datasets, documenting their fields and irregularities, choosing keys and cleaning boundaries, and designing staging models with suitable tests.
Why use it?
It prevents staging code from being designed around assumptions that do not match the source data’s quality, format, or meaning.

Written for no agent in particular: nothing here depends on one. Also seen: mentions AGENTS.md.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uv run python elt/scripts/profile_raw_source.py \.

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-dbt-model-readiness 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 9d 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.

Staging Model Readiness

在写或重写 pipeline/elt/models/staging/** 前使用本 skill。目标是先理解 raw source 的真实数据质量和数据特征,再设计 staging 清洗、字段治理和 tests。

必读入口

  1. AGENTS.md 的 dbt 入口。
  2. docs/ADR/0007-dbt-staging-cleaning-boundary.md
  3. docs/ADR/0008-raw-source-profiling-before-dbt-staging.md
  4. docs/RFC/archive/0013-raw-source-profiling-before-dbt-staging.md
  5. docs/plans/archive/0025-raw-source-profiling-before-dbt-staging-implementation-plan.md

Workflow

  1. 确认目标 staging model 和直接 raw inputs。
    • 读取 pipeline/elt/models/sources.yml
    • 读取对应 pipeline/contracts/datasets/<dataset>.yml
    • 如存在,读取 docs/references/data_dict/<dataset>.md
  2. 按 dbt discovering-data 方法完成 raw profiling。
    • inventory。
    • sample raw data。
    • row count、日期/分区范围。
    • grain 和候选自然键。
    • null、空字符串、占位值。
    • 枚举值和 top values。
    • 证券代码/日期/高价值字符串格式。
    • 数值范围、负数、零值、极端值和单位判断。
  3. 写入 docs/references/raw_profile/<dataset>.md
  4. 在 report 前半部分提炼“数据分析发现”,不要只留下 SQL 输出。
    • 数据量、覆盖范围、分区范围。
    • grain、候选键、重复情况;如存在新旧候选键,必须对比说明。
    • 关键字段 null / 空字符串 / 占位值,并解释哪些是预期缺失。
    • 证券代码、日期、报告期、状态字段等高价值字段的格式和异常样本。
    • 枚举分布、长尾文本、低频异常值;必要时补充字段间相关性。
    • 时间字段范围和业务合理性检查,例如日期先后关系。
    • 数值字段负数、零值、极端值和单位判断。
    • 只把已执行查询支持的事实写成结论;推断必须标明为判断。
  5. 从 report 中提取 staging 设计:
    • rename。
    • cast。
    • normalize。
    • null handling。
    • data tests。
    • YAML config.meta.source_columns 和 normalization metadata。
    • deferred to intermediate/mart。
  6. 只有完成 raw profile 后,再写 staging SQL/YAML。
  7. 运行验证。

Report Shape

raw profile report 应采用“结论优先,证据后置”的结构。SQL 附录用于追溯, 但 reviewer 应能先通过“数据分析发现”和“Staging 设计决策”判断模型怎么写。

推荐章节:

  1. 范围与执行信息:命令、日期、状态、contract、source、ClickHouse raw 表。
  2. 数据分析发现:用分组 bullet 写高信号事实。
    • 数据量与覆盖:总行数、distinct 主体数、分区 / 日期范围。
    • 粒度与候选键:候选键去重结果、旧键对比、重复样本归因。
    • 缺失与占位:关键字段 NULL、空字符串、1970-01-01、供应商占位。
    • 格式与参照完整性:证券代码格式、报告期标签、是否能命中直接依赖 raw input。
    • 分布与相关性:枚举 top values、少量值、长尾文本、字段间强相关。
    • 时间合理性:min/max、日期顺序异常、批次时间范围。
    • 数值合理性:负数、零值、极端值、单位假设。
  3. 字段画像:保留逐字段表,用于快速查 NULL、占位、distinct 和备注。
  4. 数据质量问题:只列实际发现的问题;通用风险不要写成问题。
  5. Staging 设计决策:明确每个清洗动作是否进入 staging、测试和 metadata。
  6. 延后到 Intermediate/Mart:跨源归并、业务优先级、主数据修正、复杂文本归一化。
  7. 待确认问题
  8. 关键 SQL 证据摘要:只放支撑结论的高信号结果。
  9. 验收清单:保持 ## 9. 验收清单 标题,兼容 readiness lint。
  10. Profiling SQL 与结果:保留高信号、可复核的查询和输出。

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.
