@fingerskier/pi-collab-ext

Sequential multi-model collaboration workflows for Pi.

Use it when you want one model to review, another to implement, and a final model to clean up without manually switching models between prompts.

Install

pi install npm:@fingerskier/pi-collab-ext

For local development:

pi install ./packages/pi-collab-ext
# or for one run only
pi -e ./packages/pi-collab-ext

Commands

/collab <json>

Starts a sequential workflow. The argument can be either a JSON array of steps or an object with a steps array.

/collab [{"model":"gpt-5.5","job":"do code review and write FINDINGS.md"},{"model":"opus-4.7","job":"implement a fix for the top issue in FINDINGS.md"},{"model":"gpt-5.5","job":"review recent changes and cleanup any related issues"}]

Object form:

/collab {"restoreModel":true,"steps":[{"model":"anthropic/claude-opus-4-7","job":"review recent changes"}]}

Fields:

• model — model shorthand (gpt-5.5, opus-4.7) or exact provider/model-id.
• job — user prompt for that step.
• thinkingLevel — optional Pi thinking level for the step: off, minimal, low, medium, high, or xhigh.
• restoreModel — optional object-level boolean. Defaults to false, leaving Pi on the last step's model.

The extension switches to each step's model, sends the step as a user prompt, waits for the agent to finish, then advances to the next step. If a model selector is ambiguous, use provider/model-id.

/collab-status

Shows the active workflow status.

/collab-stop [abort]

Stops automatic advancement. Pass abort to also abort the current model turn.

Notes

• Model changes apply to subsequent provider requests, not an already-running response.
• The workflow stops on provider error or abort so it does not continue after a failed step.
• Exact model availability depends on your configured Pi providers and auth.
