spawn

spawn is a command for coding agents from dorukanc/harness-council. It costs 17 tokens per session (116 once invoked), scanned A, original, MIT.

A command for starting a Harness Council worker, an AI worker assigned to explore, write code, or review changes. The worker can appear in a visible cmux tab, a terminal workspace for separate sessions.

In plain words
What is it for?
Use it to start exploration, implementation, or review work, then retrieve the job result or attach to the worker session.
Why use it?
It makes it easier to send a task to the appropriate kind of worker and track the resulting job.

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

spawn 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

Spawn a council worker for: $ARGUMENTS

Use the council CLI or MCP:

council spawn --role code $ARGUMENTS

If the user intent is exploration/research, use --role explore. If implementation/coding, use --role code. If review-only, use --role review.

Report the job id, status, and how to council result / council attach.

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.
