kill

kill is a command for coding agents from AutomateLab-tech/agency-os. It costs 0 tokens per session (114 once invoked), scanned A, original, MIT.

A command that stops a task and marks it as killed, including any unfinished subtasks beneath it.

In plain words
What is it for?
Use it to cancel an active task by ID and optionally record a reason; unfinished descendants are cancelled as well.
Why use it?
It removes cancelled work from the active task list and records why the task was stopped, so its status is clear later.

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

kill 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 3d 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

Command: kill <id> [--reason "..."]

Terminal drop.

  1. Sync preflight.
  2. Resolve <id> against any non-terminal row.
  3. Status -> Killed. Append ### <date>: killed — <reason> to the Done log.
  4. Cascade: for every descendant in non-terminal status, also set Status -> Killed with reason parent killed.
  5. Print: Killed: [<title>](<url>) ({<reason>}) (cascaded N descendants).

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.
