• missing deploy target: prefer

• missing secrets policy: use

  none

  env-only

Safety Rules

• Do not invent API keys, OAuth material, cookies, or tokens.
• Do not paste secrets into prompts, durable docs, example payloads, or issue comments.
• Do not copy raw MCP request payloads or raw run transcripts into Git.
• Do not mutate Multica daemon, Desktop UI, runtime config, or live agent bindings from a Flue scaffold issue.
• Do not place a real Flue app inside this workbench repo unless the issue explicitly asks for it; this repo usually records the lane, not the app.

Implementation Rules

• For a new or empty project, create

  agents/

  and

  roles/

  .
• For an existing non-empty project, create

  .flue/agents/

  and

  .flue/roles/

  .
• Pass the selected model ID explicitly to

  init({ model: "<model_id>" })

  .
• Prefer

  flue dev --target node

  or

  flue dev --target cloudflare

  for local development.
• Do not use

  flue run --target cloudflare

  ; use

  flue dev --target cloudflare

  or build and call a deployed endpoint.
• Grant host commands per prompt or skill, not globally, for CI/local sandbox agents.
• Keep starter agents close to one narrow workflow. Wider autonomy belongs in a later reviewed iteration.
