showrunner AGENTS.md

A set of AGENTS.md instructions for the Showrunner project. AGENTS.md is a file that tells coding agents about project facts, user preferences, workflows, and security rules.

In plain words
What is it for?
For guiding agents working on Showrunner, especially when changing authentication, onboarding, worker coordination, security, or setup documentation.
Why use it?
It gives agents consistent guidance about authentication, worker and director roles, security boundaries, documentation, and where product changes belong.

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.

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

showrunner 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 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.

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.

What it actually says

Learned User Preferences

  • Prefer dual-token auth: a shareable/commitable worker token so remote agents can join without cloud secrets; keep the director token secret and alone able to claim direction or mutate admin APIs.
  • showrunner init should write the director token to .env, document worker registration from committed showrunner/MCP files, and keep README/SETUP examples aligned.
  • Onboard may guide optional role specialization via show rules (dedicated workers for art, local tools, etc.) when the user wants that pattern.
  • Leave subagent fan-out to workers; directors may nudge workers to use their own subagents without over-documenting ownership mechanics.
  • For cross-user worker shows, prefer hard security boundaries beyond protocol rules (identity, admission gates, runtime posture); server-held rules should be mutable only with the director token.
  • Keep README, SETUP, and agent-facing instructions in sync whenever the auth or security model changes.
  • Product changes belong in the showrunner repo; consumer projects should re-init rather than hand-patching old scaffolding.

Learned Workspace Facts

  • Auth uses SHOWRUNNER_TOKEN (director) and SHOWRUNNER_WORKER_TOKEN (worker); the worker token is intended to be shareable/committable for remote agents.
  • The maintainer's production Fly app is separate from consumer project Fly apps; names and secrets do not collide.
  • Worker role specialization is expressed through show rules, not by showrunner owning or routing subagents.
Changes

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.
