@mrclrchtr/supi-debug

Adds shared debug-event capture and inspection for SuPi extensions in the pi coding agent.

Install

pi install npm:@mrclrchtr/supi-debug

For local development:

pi install ./packages/supi-debug

What you get

After install, this package wires the shared debug registry into three user-facing surfaces:

• /supi-debug — show recent debug events in a readable TUI report
• supi_debug — let the model query recent debug events during troubleshooting
• /supi-settings integration — configure whether events are captured and how much data is exposed

It also registers a Debug provider section for /supi-context.

Event behavior

• events are session-local
• the event buffer is cleared on session_start
• if debug capture is disabled, no events are retained
• agent-facing access is blocked, sanitized, or raw depending on settings

Rendering

/supi-debug uses a custom TUI message renderer that shows two levels of detail:

• Collapsed (default) — a one-line summary:

  3 events — rtk/rewrite +2 more
  

• Expanded — full details with timestamp, level, source/category, message, cwd, and data for each event. Click/expand the collapsed message in the TUI to reveal the full output.

Rendered fields per event:

• timestamp
• level
• source/category
• message
• optional cwd
• optional data
• optional rawData

Why collapsed by default

Event payloads can be large (full command strings, structured data). Collapsing keeps the conversation focused; expand only when you need the details.

Seeing full details without expanding

The agent-facing supi_debug tool always returns the expanded plain-text representation, which is useful for automated troubleshooting flows.

Filters

Both /supi-debug and supi_debug support the same basic filters:

• source
• level
• category
• limit

The tool also accepts:

• includeRaw — request raw event data when settings allow it

Settings

This package registers a Debug section in /supi-settings.

Available settings:

• enabled — turn session-local event capture on or off
• agentAccess — off, sanitized, or raw
• maxEvents — maximum retained events in memory
• notifyLevel — minimum severity that may notify the user: off, warning, or error

Defaults come from the shared debug registry:

{
  "debug": {
    "enabled": false,
    "agentAccess": "sanitized",
    "maxEvents": 100,
    "notifyLevel": "off"
  }
}

Extra status logging

If SUPI_LOG_STATUS is enabled in the environment, the package emits a SuPi load-status marker to stderr on session_start and appends the same payload as a session entry.
