FIT is an enterprise AI development framework with a multilingual function engine, a flow orchestration engine, and Java tools for connecting language models, knowledge bases, and external tools. It is for Java-oriented teams building AI applications that can run locally or in distributed deployments with plugins. The catalogue add-ons provide commands, skills, instructions, and settings for working with FIT.

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 | $0.00009 | $0.00579 |
| Opus 5.5 | $0.00004 | $0.00232 |
| Sonnet 5.5 | $0.00002 | $0.00116 |
| Haiku 4.5 | $0.00001 | $0.00058 |
Grade A, and why
fit-implement-task 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 2mo 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
根据技术方案实施任务 $1,编写代码和测试,输出实现报告。
执行以下步骤:
-
验证前置条件: 检查必需文件是否存在:
- .ai-workspace/active/$1/task.md
- .ai-workspace/active/$1/plan.md 如果任一文件不存在,提示用户先完成前置步骤。
-
读取技术方案: 仔细阅读 .ai-workspace/active/$1/plan.md,理解:
- 技术方案和实现策略
- 详细的实施步骤
- 需要创建/修改的文件清单
- 测试策略
-
执行代码实现: 按照 plan.md 中的步骤顺序执行:
- 按照方案实现功能代码
- 编写完整的单元测试
- 遵循项目编码规范(参考 AGENTS.md)
- 修改带版权头的文件时,先运行
date +%Y获取当前年份并更新版权头
-
运行测试验证:
mvn test -pl :<module-name>确保所有测试通过。
-
输出实现报告: 创建 .ai-workspace/active/$1/implementation.md,包含:
- 已修改文件列表(新增文件和修改文件)
- 关键代码说明(重要逻辑的解释和代码片段)
- 测试结果(测试用例数、通过率、测试输出)
- 与方案的差异(如果有)
- 待审查事项(需要 reviewer 关注的点)
-
更新任务状态: 使用 Edit 工具更新 .ai-workspace/active/$1/task.md:
- current_step: implementation
- assigned_to: codex
- updated_at: 当前时间
- 标记 implementation.md 为已完成
- 在"工作流进度"中标记 implementation 为完成 ✅
-
告知用户:
- 输出修改文件数、新增文件数、测试通过数
- 提示下一步进行代码审查:
- Claude Code / OpenCode: /review-task $1
- Gemini CLI: /fit:review-task $1
- Codex CLI: /prompts:fit-review-task $1
注意事项:
- 严格遵循 plan.md,不要偏离技术方案或添加计划外功能
- 每完成一个步骤就运行测试
- 不要自动执行 git commit,等待代码审查通过后由用户提交
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.
- 2mo ago First seen · 63 lines · 9 tokens per session scan A 105333064e71
fit-implement-task is a command published in the GitHub repository ModelEngine-Group/fit-framework (2,117 stars, last pushed 7mo ago), licensed MIT. It adds 9 tokens to every session and 579 once invoked, about $0.0000 per session on Opus 5.5. 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.
