block-task

A command for marking a work item as blocked, recording why it cannot continue, and moving it to a blocked-task folder.

In plain words
What is it for?
Use it when a task cannot proceed, such as after an unresolved build or test failure, an unclear requirement, or a missing dependency.
Why use it?
It keeps unfinished work and its cause visible when a task depends on clarification, a fix, a resource, or an outside dependency.

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

block-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 2d 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

标记任务阻塞

使用场景

  • 编译失败且无法修复
  • 测试失败且原因不明
  • 依赖库存在 Bug
  • 需求不明确,需要澄清
  • 等待外部依赖

执行步骤

  1. 验证任务存在:

    test -f .ai-workspace/active/<task-id>/task.md && echo "任务存在" || echo "任务不存在"
    
  2. 分析并记录阻塞原因(类型: 技术问题/需求问题/资源问题/决策问题)。

  3. 更新 task.md: status -> blocked, blocked_at, blocked_reason。

  4. 添加"阻塞信息"章节。

  5. 移动到阻塞目录:

    mkdir -p .ai-workspace/blocked && mv .ai-workspace/active/<task-id> .ai-workspace/blocked/
    
  6. 解除阻塞时:

    mv .ai-workspace/blocked/<task-id> .ai-workspace/active/
    
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.
