Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00064 | $0.01779 |
| Opus 5 | $0.00032 | $0.00890 |
| Sonnet 5 | $0.00013 | $0.00356 |
| Haiku 4.5 | $0.00006 | $0.00178 |
Grade A, and why
conductor 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Conductor
CLI tool for defining and running multi-agent workflows with the GitHub Copilot SDK, Anthropic Claude, Claude Agent SDK, or Hermes (NousResearch, experimental).
DO NOT create new workflow files unless the user explicitly asks you to create one. Default to running, validating, or debugging existing workflows. If the user's request is ambiguous, assume they want to run or modify an existing workflow rather than create a new one.
Error Handling
CRITICAL — do NOT improvise workarounds. If
conductorfails for any reason (installation failure, provider error, missing dependency, platform bug), you MUST:
- Report the exact error to the user — include the full error message.
- Stop and wait for user direction. Do NOT attempt to simulate, replicate, or approximate the multi-agent workflow yourself. The value of this skill is the structured multi-agent orchestration — a single-agent attempt is not an equivalent substitute.
Setup
Conductor is installed automatically when needed. If a conductor command fails with "command not found", install it. For installation instructions, see references/setup.md.
Quick Reference
conductor run workflow.yaml --input question="Hello" # Execute (full output by default)
conductor -q run workflow.yaml --input question="Hello" # Quiet: lifecycle + routing only
conductor -s run workflow.yaml --input question="Hello" # Silent: JSON result only
conductor run workflow.yaml --log-file auto # Log full debug output to file
conductor run workflow.yaml --web --input q="Hello" # Real-time web dashboard
conductor run workflow.yaml --web-bg --input q="Hello" # Background mode (prints URL, exits)
conductor run workflow.yaml -m tracker=ado -m work_item=42 # Attach metadata (merged on top of YAML)
conductor run workflow.yaml --workspace-instructions # Auto-discover AGENTS.md / CLAUDE.md / etc.
conductor validate workflow.yaml # Validate (schema + semantic checks)
conductor show workflow.yaml # Show inputs, agents, and outputs
conductor replay events.jsonl # Replay a recorded run in the dashboard
conductor registry add official myorg/workflows --default # Add a registry (--type github|path)
conductor registry list official # List registry workflows
conductor run qa-bot@[email protected] --input q="Hello" # Run from registry
conductor stop # Stop background workflow
conductor update # Check + print install command
conductor update --apply # Check + launch installer (then exit)
conductor resume workflow.yaml # Resume from last checkpoint
conductor resume workflow.yaml --web # Resume with dashboard (run-flag parity)
conductor checkpoint list # List available checkpoints
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 is a skill published in the GitHub repository microsoft/conductor (408 stars, last pushed 4d ago), licensed MIT. It adds 64 tokens to every session and 1,779 once invoked, about $0.0003 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 2026-08-30.
