plan-task

A planning step for software tasks that reads the task analysis, compares possible technical solutions, and records the chosen approach in a plan.

In plain words
What is it for?
Use it to compare solutions, list files and dependencies, define implementation steps, and decide how the work will be checked.
Why use it?
It turns an understood problem into a reviewed implementation plan before anyone changes code.

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-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 yesterday.

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

设计技术方案

执行步骤

  1. 查找任务文件(搜索 active/blocked/completed 目录)。

  2. 读取 analysis.md,理解:

    • 问题的根本原因和影响范围
    • 技术约束和特殊要求
    • 相关文件和依赖关系
  3. 设计解决方案:

    • 提出多个可行方案并对比优劣
    • 选择最合适的方案并说明理由
    • 制定详细的实施步骤
    • 列出需要创建/修改的文件清单
    • 设计验证策略
  4. 输出方案文档到 plan.md。

  5. 更新任务状态,标记 technical-design 为完成。

  6. 提示这是人工审查检查点,审查通过后使用 implement-task skill。

注意: 充分思考,不要急于实施。方案设计完成后等待人工审查。

Changes

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.

plan-task is a skill published in the GitHub repository ModelEngine-Group/fit-framework (2,117 stars, last pushed 5mo ago), licensed MIT. It adds 36 tokens to every session and 245 once invoked, about $0.0002 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 2026-08-30.
