orchestrator AGENTS.md

orchestrator AGENTS.md is an instructions file for Codex, OpenCode from c9r-io/orchestrator. It costs 1,468 tokens per session, scanned A, original, MIT.

Project instructions for an AI development platform that coordinates coding agents through YAML workflow files. It describes how agents, tasks, workers, and the background service fit together.

In plain words
What is it for?
Use it when changing the orchestrator, its command-line tool, background service, workflow manifests, agent coordination, persistence, or sandboxing.
Why use it?
It gives agents the project rules and architecture they need to work safely and consistently. It also explains how long-running, multi-step work is managed.

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

orchestrator AGENTS.md 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.

Agent Orchestrator — AI Dev Platform Index

Project Overview

This project is an Agent Orchestrator — a Harness Engineering control plane for agent-first software delivery. It turns shell-native coding agents (Claude Code, OpenCode, Codex, Gemini CLI, etc.) into governed execution units that participate in long-running, multi-step engineering workflows through Kubernetes-style YAML manifests.

Core Capabilities

  • Workflow Orchestration: Declarative multi-step workflows with loop control, guard steps, DAG execution, and CEL-based prehooks
  • Agent Orchestration: Capability matching, health scoring, rotation, and load balancing across heterogeneous shell agents
  • Long-running Automation: Task persistence, event streams, trigger-based task creation (cron/event/webhook), and guarded workflow loops

Architecture

orchestrator (CLI) ──gRPC/UDS──> orchestratord (daemon)
                                    ├── gRPC server (tonic)

                                    └── Sandbox enforcement

Key design principles:

  • Capability-driven orchestration: Steps declare required capabilities, agents declare supported capabilities
  • Dynamic agent selection: Strategies include CapabilityAware, CostBased, SuccessRateWeighted, PerformanceFirst, Adaptive, LoadBalanced
  • Declarative workflow definitions: Steps can be builtin (init_once, ticket_scan, self_test, self_restart, item_select, loop_guard) or capability-based
  • CEL prehooks: Conditional step execution via CEL boolean expressions
  • Guard steps: Steps that can terminate the workflow loop based on their output
  • Dynamic step pools: Runtime step selection based on context and priority
  • DAG execution engine: Topological sort, cycle detection, conditional edges
  • Built-in observability (structured logs, event streams, task lifecycle tracking)

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.
