brief

brief is a skill for Claude Code, Codex from wrg32786/aigent-os. It costs 10 tokens per session (293 once invoked), scanned A, original, MIT.

A command that turns a task description into a structured brief for another AI agent. It gathers project context, suggests a recipient and priority, and asks for approval before sending.

In plain words
What is it for?
Use it to prepare clear, verifiable delegation requests for sub-agents.
Why use it?
It removes the work of deciding what context, constraints, deliverables, and checks to include when handing off a task.

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

brief 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 5d 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

Delegation Brief Generator

Quickly create a structured brief for delegating work to a sub-agent. Uses the template from system/05_delegation_protocol.md.

Usage

/brief [task description]

What It Produces

## Brief: [Task Name]

**From:** the AIgent
**To:** [Recommended agent based on task type]
**Priority:** [P0/P1/P2 based on context]
**Date:** [Today]

### Objective
[One sentence derived from the task description]

### Context
[Relevant context pulled from vault — active priorities, related project notes, recent decisions]

### Deliverable
[Specific, verifiable output]

### Constraints
[Time, scope, dependencies inferred from context]

### Verification
[How to check the work is actually done]

Behavior

  1. Parse the task description from the user's input
  2. Check vault/memory/ACTIVE_PRIORITIES.md to understand current mode and context
  3. Check vault/memory/DELEGATION_TRACKER.md for related pending work
  4. Determine the right agent and priority level
  5. Draft the brief using the delegation protocol template
  6. Present to the principal for approval before sending

Always recommend a model tier for the receiving agent based on task complexity.

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.
