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 | $0.00685 | $0.00685 |
| Opus 5 | $0.00342 | $0.00342 |
| Sonnet 5 | $0.00137 | $0.00137 |
| Haiku 4.5 | $0.00068 | $0.00068 |
Grade A, and why
cesium-mvt AGENTS.md 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 8d 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.
What it actually says
协作约定
1. 基本要求
- 始终使用中文交流。
- 任何实现都必须走 TDD 流程：先补会失败的测试，再改实现，最后补齐回归验证。
- 文件、目录命名统一使用小写烤串式。
- 优先使用仓库现有的技能、脚本和工具链，不重复造轮子。
2. 设计原则
- 以生产标准为目标，不要为了迁就旧实现而新增兼容层。
- 先确认根因，再做结构性修复，不要靠不断叠加判断兜底。
- 不要把逻辑持续堆进单个大文件，优先拆成职责清晰的小模块。
- 命名要语义清晰，避免过多定语修饰。
- 对复杂代码补中文注释，说明原因、约束或关键思路，不解释显而易见的动作。
- 不编写无意义的桥接函数、桥接类、桥接文件。
- 一旦确认正确模型，就收敛到单一实现，不保留新旧双轨逻辑。
- 优先复用 Cesium、MapLibre 及其子模块已经提供的能力、状态和语义，不重复实现已有机制。
CesiumVectorTile的整体设计应尽量贴近Cesium3DTileset的 API 形态，同时参考 MapLibre 的 MVT 渲染流程。- 例如：
fromUrl优先接收Resource | string。- 缓存策略既要参考
Cesium3DTileset，也要参考 MapLibre 的瓦片缓存与替换思路。 - 分层渲染可以参考 MapLibre，但实现方式优先采用 Cesium 的语义和生命周期。
- 具体行为上，先判断哪一边的语义更贴近当前目标，再决定，不要机械照搬其中任何一方。
3. 修改策略
- 修复问题时优先解决根因，不要只修现场症状。
- 不要盲改；如果无法稳定复现，先补测试或日志定位，再改实现。
- 涉及缓存、生命周期、GPU 资源时，必须同时检查性能影响和内存泄漏风险。
- 对外 API、数据模型和缓存语义的变更，必须同步更新测试和文档。
4. 测试与校验
- 编写测试时，引用
src目录必须使用@/别名。 - 新功能必须补测试。
- 修复 bug 必须补对应回归测试，确保问题不会再次出现。
- 修改代码后必须运行：
pnpm lint:eslint --fixpnpm lint:tsc
5. 禁止事项
- 不要为了“先跑起来”引入临时兼容代码。
- 不要保留已经确认错误的数据模型。
- 不要在没有验证的前提下持续叠加补丁。
- 不要为了局部方便牺牲整体设计一致性。
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.

cesium-mvt AGENTS.md is an instructions file published in the GitHub repository xiankq/cesium-mvt (10 stars, last pushed 4mo ago), licensed MIT. It adds 685 tokens to every session, about $0.0034 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 2026-08-31.
