subagent-orchestrator

subagent-orchestrator is a skill for Claude Code, Codex from kok-o/koko-contextos-agents. It costs 33 tokens per session (845 once invoked), scanned A, original, MIT.

A method for coordinating multiple coding agents by splitting work into separate tasks, giving each agent limited context, and combining their results. It prevents agents from editing the same files at the same time.

In plain words
What is it for?
It helps divide work across modules, services, test suites, research tasks, security reviews, and documentation work.
Why use it?
It makes large or parallelizable work easier to organize and reduces conflicts when separate agents work on different parts of a project.

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-orchestrator 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 6d 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.

subagent-orchestrator

Overview

Multi-agent coordination protocol inspired by obra/superpowers. Enables a primary orchestrating agent to decompose complex workflows into isolated, parallel sub-tasks, delegate them with precise context boundaries, monitor execution, and synthesize outputs with zero merge conflicts.

When to Use

Activate whenever:

  • A task can be parallelized across distinct modules, services, or test suites.
  • Long-running exploratory research or multi-file refactoring exceeds single-context budget.
  • Running autonomous subagent workers for specialized roles (e.g. specialized QA tester, Security auditor, Docs generator).

Rules & Patterns

1. The Blast Radius Boundary Rule

Before delegating any subagent task:

  • Zero File Overlap: Each subagent MUST have a mutually exclusive list of target files. Two subagents must never be instructed to edit the same file concurrently.
  • Explicit Inputs & Outputs: Provide only the minimal schema, contract, or mock that the subagent needs. Do not dump the entire workspace into subagent prompts.

2. The 4-Step Delegation Lifecycle

[ Orchestrator ]
       │
       ├─▶ 1. DECOMPOSE: Break into orthogonal tasks with non-overlapping file sets
       │
       ├─▶ 2. DISPATCH: Launch subagent with precise goal, constraints, and finish criteria
       │
       ├─▶ 3. AWAIT & VERIFY: Validate subagent output against its individual quality gate
       │
       └─▶ 4. SYNTHESIZE: Merge subagent results into the main branch and run global regression suite

3. Context Hand-off Specification

Every subagent dispatch prompt must contain:

  1. Target Objective: Single, verifiable deliverable.
  2. Read-Only Context: Files to consult as reference without modifying.
  3. Write Scope: Exact file paths the subagent is permitted to create or modify.
  4. Completion Signal: Explicit instruction to report DONE with test evidence or BLOCKED with reason.

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.

subagent-orchestrator is a skill published in the GitHub repository kok-o/koko-contextos-agents (2 stars, last pushed 7d ago), licensed MIT. It adds 33 tokens to every session and 845 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 2026-09-05.
