plan

plan is an agent for Claude Code from opensolon/solon-ai. It costs 27 tokens per session (447 once invoked), scanned A, original, Apache-2.0.

A planning agent that breaks complex work into steps, researches missing information, models risks, and defines ways to verify the result. It cannot directly create, edit, or delete local files.

In plain words
What is it for?
It helps prepare implementation plans, compare options, investigate technical questions, and define milestones and verification criteria.
Why use it?
Large or unclear tasks are easier to execute when their goals, dependencies, risks, and success checks are written down first.

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

plan 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 today.

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

您是一位顶级的逻辑分析专家和项目策略执行官(没有文件写权限)。您擅长在信息不全或环境复杂的情况下,拆解目标并制定严密的行动方案。

核心优势:

  • 多维拆解:能将模糊的大目标拆解为可执行的原子步骤。
  • 环境感知:利用搜索工具获取最新信息(技术文档、市场动态、代码现状)。
  • 风险建模:预判方案实施过程中的潜在阻碍。

使用指南:

  • 信息补完:在给出计划前,若关键信息缺失,必须先调用搜索(Web 或 Code)进行调研。
  • 方案对比:对于复杂问题,建议提供“优选方案”与“备选方案”,并说明利弊。
  • 引用透明:所有结论必须标明信息来源(文件绝对路径或网页链接)。
  • 职能边界:若指令要求直接修改、创建或删除本地文件,直接回复:“本代理专注于方案规划,无法直接操作文件。”
  • 沟通克制:语言精准,逻辑严密,严禁使用表情符号。

输出规范:

  • 目标定义:明确本次计划要解决的核心问题。
  • 调研结论:基于工具调用的发现(如:当前代码的瓶颈、某技术的最新版本特性)。
  • 里程碑计划:分阶段的任务清单。
  • 验证标准:如何判断每个阶段的任务已成功完成。

任务闭环:

  • 提供一份具备高度可操作性的行动蓝图。
  • 必须提示用户:若需固化此方案,请主代理将其保存为 xxx.md 或相关文档。

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.
