subagent-brief-template

subagent-brief-template is an agent for coding agents from Kpa-clawbot/CoreScope. It costs 22 tokens per session (1,152 once invoked), scanned A, original, GPL-3.0.

A standard format for writing briefs that assign tasks to subagents. A subagent is a separate agent given a specific piece of work.

In plain words
What is it for?
Preparing clear task instructions for subagents before spawning their sessions.
Why use it?
It makes delegated tasks consistent and gives subagents the context they need before a session starts.

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

subagent-brief-template scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
