collab

collab is a skill for Claude Code, Codex from AgentBuildersApp/eight-eyes. It costs 36 tokens per session (2,907 once invoked), scanned A, original, MIT.

A coordinator for multi-agent coding missions, where several specialized agents work through a review, implementation, or audit in stages.

In plain words
What is it for?
It helps run multi-agent reviews, implementations, and audits with specialized roles, ordered phases, shared results, and safety checks.
Why use it?
It manages handoffs, checks that agent results follow the required format, and blocks work when scope or mission rules are violated.

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

collab 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 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.

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.

collab -- Coordinator Instructions

You are the coordinator of a collab mission. Your job is to drive an objective through a sequence of phases, dispatching specialized subagent roles and collecting their results.

When to Activate

  • User runs /collab <objective>
  • User explicitly asks for multi-agent review, implementation, or audit
  • User requests consensus from multiple specialist perspectives

Trust Boundaries

The coordinator is trusted -- full tool access, no scope enforcement. Hook-based scope enforcement applies only to subagent roles.

Gate hierarchy

Hook Gate class Behavior
PreToolUse hard-deny Blocks tool calls that violate role scope. Primary trust anchor for subagents.
SubagentStop hard-block Validates result schema and blocks the mission if a role emits malformed output.
PostToolUse recovery Audit trail and recovery actions (e.g., revert detection). NOT the primary trust anchor.
Stop warn Warns on session exit with unfinished mission work. Does not block unconditionally.
SessionStart continuity Restores manifest context after compaction or new session. Continuity aid.
PreCompact continuity Snapshots manifest before context-window trim. Continuity aid.
SubagentStart continuity Injects role scope and instructions into subagent prompt. Continuity aid.

Hard gates (PreToolUse, SubagentStop) are the enforcement boundary. Lifecycle/context hooks (SessionStart, PreCompact, SubagentStart) are continuity aids -- they keep state coherent but are not equivalent hard gates.

Run collabctl capabilities for the full enforcement model.


Phase Model

Every mission follows this primary phase sequence:

[research] -> plan -> implement -> test -> audit -> verify -> [docs] -> close

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.

collab is a skill published in the GitHub repository AgentBuildersApp/eight-eyes (2 stars, last pushed 1mo ago), licensed MIT. It adds 36 tokens to every session and 2,907 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
