fleur-dagster-http-source

fleur-dagster-http-source is a skill for Claude Code, Codex from WackyGem/Fleur. It costs 99 tokens per session (2,461 once invoked), scanned A, original, MIT.

A guide for turning one remote HTTP link into a data pipeline that stores Parquet files in S3 and raw data in ClickHouse. Parquet is a column-based file format, while S3 is object storage.

In plain words
What is it for?
It helps document an endpoint, define dataset fields, generate a Dagster source asset, and connect the downloaded data to ClickHouse raw storage.
Why use it?
It prevents a new remote dataset from becoming an isolated script by recording its source, fields, and storage rules in the project’s existing structure.

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-dagster-http-source scanned grade A with 1 finding 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 6d 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.

Dagster HTTP Source Asset

当用户只提供一个远端 HTTP 链接,并希望生成 HTTP -> S3 Parquet -> ClickHouse raw 链路代码时,使用本 skill。

目标不是生成孤立 asset,而是把新数据集纳入 fleur 的长期边界:

  • 远端接口事实记录在 docs/references/remote_endpoint/
  • 字段事实源记录在 pipeline/contracts/datasets/*.yml
  • Dagster source asset 写入 contract 精确匹配的 S3 Parquet。
  • ClickHouse raw asset 由 pipeline/contracts 中的 clickhouse_raw 自动生成。

配合使用

  • 先使用 dagster-expert,并按需读取 asset metadata、dependency 和 dg check reference。
  • 涉及 contract、Parquet schema、ClickHouse raw 字段时使用 fleur-contract-data-dictionary
  • 写 Python 代码或测试时使用 dignified-python
  • 需要实际 materialize、回填或重跑时使用 fleur-dagster-backfill-runbook
  • 涉及 Dagster、ClickHouse client、PyArrow、dbt 等库/CLI 的 API 细节时,按 AGENTS.md 使用 Context7。

输入归一化

最小输入可以只有一个 URL。先把它归一化成下面事实,不足时自己探测;只有鉴权、 业务口径或目标数据集命名无法安全推断时才问用户。

  • source:供应商或站点名,作为 source bundle 名和 asset tag。
  • dataset:形如 <source>__<entity>,作为 source asset 尾段、contract 文件名和 raw table 名。
  • endpoint:HTTP method、URL、query params、headers、referer、分页和速率限制。
  • payload_format:JSON、CSV、TXT、ZIP 等。
  • grain:一行代表什么。
  • storage_modelatest_snapshotpartitioned
  • partition_key_name:仅 partitioned 需要,如 yeartrade_date
  • raw_sync:是否同步到 ClickHouse raw;不能确定时默认做 source-only,并在最终说明原因。

如果 URL 需要 token、cookie、账号密码或私有 header,不能把密钥写进代码、文档或最终回答; 应使用现有 .env/resource/config 模式,缺少变量时向用户要变量名或鉴权方式。

Endpoint Profiling

  1. 先读入口文档:AGENTS.mddocs/architecture/scheduler-architecture.mddocs/architecture/scheduler-module-boundaries.md
  2. 查已有事实:docs/references/remote_endpoint/<dataset>.mdpipeline/contracts/datasets/<dataset>.yml、同源 pipeline/scheduler/src/scheduler/defs/sources/<source>/
  3. curl 或现有 HTTP client 探测 URL。公开接口可以直接取小样本;需要鉴权或大量数据时只记录阻塞原因。
  4. 记录或更新 docs/references/remote_endpoint/<dataset>.md,至少包含: endpoint、请求示例、参数表、响应结构、分页/游标、错误码、保留期限、headers、速率限制和样例字段。
  5. 不从字段名凭空编业务含义。中文描述无法确认时按 contract skill 使用“待核实”格式。

Contract First

新增或修改 source asset 前,先维护 pipeline/contracts/datasets/<dataset>.yml

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-dagster-http-source is a skill published in the GitHub repository WackyGem/Fleur (114 stars, last pushed 1mo ago), licensed MIT. It adds 99 tokens to every session and 2,461 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
