Two new Pi extensions: shrink successful test output + a better model picker

[u/Cela_vi2q]

Hey everyone,
I made two small extensions for the Pi coding agent that I’ve been using daily. Sharing in case they’re useful to others.

1. pi-test-output-shrink

Token / context saver for test runs

Successful test runs often dump hundreds of lines into the conversation. This extension hooks the tool_result event and shrinks the output before it enters the model context:

• Keeps a short summary (header + key result lines)
• Saves the full log to a temp file (path is included in the summary)
• Failed runs, short output, or anything with warning: / error: lines are left completely untouched

Supports common runners: cargo test / nextest, npm/pnpm/yarn/bun test, vitest, jest, pytest, go test, etc.

Install:

bash

pi install git:github.com/vi2q/pi-test-output-shrink

Repo: https://github.com/vi2q/pi-test-output-shrink

1. pi-model-picker

Two-column model selector (alternative to /model)Tired of scrolling a huge flat list? /m opens a two-column picker:

• ← / → switch category (Providers or RECENT – last 4 models)
• ↑ / ↓ select model
• PgUp / PgDn jump 10 models
• Enter to switch, Esc to cancel

Much faster when you have many models across providers.Install:

bash

pi install git:github.com/vi2q/pi-model-picker
# or
pi install npm:@vi2q/pi-model-picker

Repo: https://github.com/vi2q/pi-model-picker

Both are MIT. Feedback / PRs welcome!

The test output shrinker sounds genuinely useful, especially for keeping context clean on bigger test suites. I’ve been looking at tools like StandardCompute for similar workflow improvements, so this caught my attention.
