orchestrator-contractMUST activate when you ARE an orchestrator — you are the top-level agent, you spawn subagents, you delegate work, you coordinate parallel or sequential execution.
Orchestrator Contract is an agent skill from griddynamics/rosetta. MUST activate when you ARE an orchestrator — you are the top-level agent, you spawn subagents, you delegate work, you coordinate parallel or sequential execution. Defines delegation quality, subagent dispatch, routing, review, and ownership protocol.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Subagents. The repository describes itself as: An instruction layer for AI coding agent. The licence is Apache-2.0.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 5441232. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Orchestrator Contract loads about 1.2k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 582 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Topology:
trusts but verify, if anything could go wrong - it will go wrong, provides clear context and instructions, subagents can cheat, consults with architect, and uses subagents as its team. It adapts and tunes management best practices to the specific user request. It tells WHAT to do and HOW to think, does not do subagents' tasks itself, but organizes them and encourages thinking over mechanical work. It appends to instructions instead of paraphrasing, uses MoSCoW, and grounds subagents with references to files, instructions, phases, steps, and skills instead of duplicating.Dispatch:
""" You are [role/specialization]. [Lightweight|Full] subagent.
Target root folder: [path] [git worktree?] DO: [what is in scope, explicit expected outputs and clear expectations] DO NOT: [what is explicitly out of scope, what is read-only, what not to touch — forbid out-of-scope work; do not improvise beyond defined scope]
MUST USE SKILL [required skill]. RECOMMEND USE SKILL [recommended skill].
[original user request/intent verbatim — always provide throughout all steps]
[specific task, full context, and references — subagents know nothing except shared bootstrap, prep steps, and this contract; provide everything needed]
[output can be just response message or written to file (or both - based on the task and expected volume); unique output file path per subagent and format if output to file is needed; for large output define exact path and required file format/template; or expected report-back summary — include only what applies]
[require that all claims, findings, and recommendations include proofs, references, and deep links with line ranges; include brief source quotes; explicitly distinguish verified facts from assumptions]
[free form anything else that was not provided, additional information, requirements, specifications, context, etc.] """

Quality:
Review = static inspection (recommendations). Validate = running on real/sample tasks (catches real issues, expensive).</process>

Explains how to write agents for Claude Code plugins: the markdown file with YAML frontmatter, trigger descriptions, model and color settings, and system prompt design.
Asvarox/allkaraoke
A skill your agent uses when executing implementation plans with independent tasks in the current session
ultralisp/ultralisp
A skill your agent uses when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
getpaseo/paseo
Launches one separate agent through Paseo to give a second opinion on the current task, with a self-contained briefing and no permission to edit files.
rebelytics/one-skill-to-rule-them-all
Monitors task execution for skill improvement opportunities.
openobserve/openobserve
Splits a change into planner, coder and independent reviewer roles: you confirm a spec, a subagent implements it, and a separate reviewer checks each round's local WIP commit.
griddynamics/rosetta
Collect GitHub repo health/usage stats into merged JSON. An agent skill from griddynamics/rosetta.
griddynamics/rosetta
Workflow for onboarding an external private library so AI can use it without source access.
griddynamics/rosetta
To connect Rosetta with Grid Dynamics SpecFlow MCP; only when SpecFlow is mentioned and the MCP is installed.
griddynamics/rosetta
To build an AI harness: run, observe, validate, automate repeated work faster — CLI/MCP actions, devcontainers, skills, subagents, hooks, pipelines, automations.
griddynamics/rosetta
To orchestrate parallel coding-agent farms (Claude, Codex, Copilot, Gemini, etc.) on isolated git worktrees.
griddynamics/rosetta
To author, register, and test Rosetta hooks, add a SemanticKind, or debug a hook that won't fire.

MUST activate when you ARE an orchestrator — you are the top-level agent, you spawn subagents, you delegate work, you coordinate parallel or sequential execution. Orchestrator Contract is an agent skill from griddynamics/rosetta. MUST activate when you ARE an orchestrator — you are the top-level agent, you spawn subagents, you delegate work, you coordinate parallel or sequential execution.
Orchestrator Contract fits situations like: tasks that involve Subagents.
Run `npx skills add griddynamics/rosetta --skill orchestrator-contract -a claude-code`. Or copy the skill folder (instructions/r2/core/skills/orchestrator-contract in griddynamics/rosetta) into .claude/skills/orchestrator-contract in your project. Claude Code loads it when a task matches its description.
Run `npx skills add griddynamics/rosetta --skill orchestrator-contract -a codex`. Or copy the skill folder (instructions/r2/core/skills/orchestrator-contract in griddynamics/rosetta) into .agents/skills/orchestrator-contract in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add griddynamics/rosetta --skill orchestrator-contract -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/orchestrator-contract, .gemini/skills/orchestrator-contract, .github/skills/orchestrator-contract and .opencode/skills/orchestrator-contract in your project.
SKILL.md names no scripts, command-line tools or credentials: Orchestrator Contract is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Orchestrator Contract is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.2k tokens (SKILL.md is roughly 4.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Orchestrator Contract: Claude Code Agent Development (anthropics/claude-plugins-official, 38k stars), Subagent Driven Development (Asvarox/allkaraoke, 261 stars), Dispatching Parallel Agents (ultralisp/ultralisp, 258 stars) and Paseo Advisor Second Opinion (getpaseo/paseo, 20k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
griddynamics (a GitHub organization) maintains it in griddynamics/rosetta, which has 354 GitHub stars. The repository holds 12 skills in this directory. The repository was last updated on September 29, 2026.
