conductor AGENTS.md

A project guide for Conductor, a command-line tool that runs workflows involving multiple AI agents. It lists the project structure, setup commands, tests, checks, and ways to run workflows.

In plain words
What is it for?
Use it when changing Conductor: install dependencies, run all or selected tests, check formatting and types, start workflows, or open the workflow dashboard.
Why use it?
It gives a coding agent the project context and the exact commands needed to work safely in the repository, so it does not have to guess how to install, test, or run the software.

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 B, and why

conductor AGENTS.md scanned grade B with 3 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 yesterday.

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.

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

Project Overview

Conductor is a CLI tool for defining and running multi-agent workflows with the GitHub Copilot SDK. Workflows are defined in YAML and support parallel execution, conditional routing, loop-back patterns, and human-in-the-loop gates.

Common Commands

# Install dependencies
make install          # or: uv sync
make dev              # install with dev dependencies

# Run tests
make test                                           # all tests
uv run pytest tests/test_engine/test_workflow.py   # single file
uv run pytest -k "test_parallel"                   # pattern match

# Run tests with coverage
make test-cov

# Lint and format
make lint             # check only
make format           # auto-fix and format

# Type check
make typecheck

# Run all checks (lint + typecheck)
make check

# Run a workflow
uv run conductor run workflow.yaml --input question="What is Python?"

# Run with web dashboard
uv run conductor run workflow.yaml --web --input question="What is Python?"

# Run in background (prints dashboard URL and exits)
uv run conductor run workflow.yaml --web-bg --input question="What is Python?"

# Stop a background workflow
uv run conductor status                 # list background workflows, never stops one
uv run conductor status --json          # machine-readable
uv run conductor stop                  # auto-stop if one running, list if multiple
uv run conductor stop --port 8080      # stop specific port
uv run conductor stop --all            # stop all background workflows

# Update conductor
uv run conductor update                # check for updates and print the install-script command
uv run conductor update --apply        # launch the installer automatically (conductor exits to release file locks)

# Resume a failed workflow from checkpoint
uv run conductor resume workflow.yaml                  # resume from latest checkpoint
uv run conductor resume workflow.yaml --web            # resume with dashboard
uv run conductor resume workflow.yaml --web-bg         # resume with background dashboard
uv run conductor resume workflow.yaml --provider copilot
uv run conductor resume workflow.yaml -m tracker=ado
uv run conductor checkpoint list       # list available checkpoints

# Acquire and inspect a workflow's git-backed plugins
uv run conductor plugin fetch workflow.yaml   # prime the cache (the CI step)
uv run conductor plugin list workflow.yaml    # what a run would load; cache-only

# Validate a workflow
uv run conductor validate examples/simple-qa.yaml
make validate-examples    # validate all examples

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.

conductor AGENTS.md is an instructions file published in the GitHub repository microsoft/conductor (408 stars, last pushed 3d ago), licensed MIT. It adds 40,861 tokens to every session, about $0.2043 per session on Opus 5. A static security scan graded it B with 3 findings (reads mcp configuration, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
