Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00081 | $0.00830 |
| Opus 5.5 | $0.00032 | $0.00332 |
| Sonnet 5.5 | $0.00016 | $0.00166 |
| Haiku 4.5 | $0.00008 | $0.00083 |
Grade A, and why
api-data-platform 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- 现有 routes、schema、OpenAPI、curl、SDK、README What it actually says
coff0xc-api-data-platform
快速规则（日常任务先读这里）
[契约先行] 先定 endpoint/action、schema、auth、错误码、分页、版本和兼容边界，再谈实现。 [数据门禁] 明确 source/raw/assumptions、迁移、回滚、幂等、审计字段和异常数据处理。 [交付标准] 输出可执行契约、样例请求响应、测试/迁移验证和破坏性变更说明。 [硬边界] 生产数据库、真实迁移、外部客户接口、凭据和远程写入先确认。
普通 API/数据任务按本节先推进；只有跨域产品、发版门禁或 schema/auth 大改才展开完整工作流。
能力定位
面向 API、数据库、CLI/SDK 和数据契约的工程能力。目标是让接口可使用、可演进、可测试，数据链路可迁移、可追踪、可恢复。
能交付什么
- REST/GraphQL/OpenAPI 契约
- 数据库 schema、迁移和数据一致性建议
- CLI/SDK 命令设计、JSON 输出和错误模型
- 兼容性、分页、认证和幂等策略
可以接收什么输入
- 现有 routes、schema、OpenAPI、curl、SDK、README
- 数据库表结构、迁移脚本、查询样例
- 错误日志、客户端调用点、数据质量问题
放心使用的边界
- 可直接做本地契约设计、代码实现和只读检查
- 生产数据库迁移、数据删除、远程 API 写入必须先确认
- 示例中不写真实 token、cookie、账号或客户数据
- 默认只处理本地、可逆、可验证的低风险工作；涉及生产、凭据、付费、远程写入、删除、发布或权限变更时必须先确认。
为什么可以放心
- 先发现现有契约风格，再设计变更
- 强调机器可解析输出和明确错误
- 迁移和公共 API 变更必须说明兼容影响
典型使用方式
使用 coff0xc-api-data-platform 设计这个 billing REST API，包含 OpenAPI、分页和错误码。
使用 coff0xc-api-data-platform 梳理 GraphQL 查询、SQL 表结构和数据质量检查。
Use coff0xc-api-data-platform to turn these curl examples into a stable CLI and SDK plan.
默认输出
- 收口只写完成、验证、还剩、下一步；有文件/代码/规则产物给路径或位置。
- 未真实运行的检查标为未验证，安全/架构结论标证据等级。
按需展开
- 日常任务只执行上面的快速规则、能力边界和典型用法，不默认读取完整门禁。
- 深度架构、复杂多阶段、质量评测、发版、正式交付或当前任务证据不足时，再读取
references/full-workflow.md。 - 读取 reference 后仍保持最小必要上下文；不要因为 reference 存在就输出长篇流程或额外自证材料。
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

api-data-platform is a skill published in the GitHub repository cass-2003/local-workflow-skill (12 stars, last pushed 3mo ago), licensed MIT. It adds 81 tokens to every session and 830 once invoked, about $0.0003 per session on Opus 5.5. 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.
