pi-pact

Pact improves Pi by retaining recent messages when compacting.

Install

Install from npm:

pi install npm:pi-pact

Run temporarily without installing:

pi -e npm:pi-pact

Configuration

Pact reads configuration in this order, with later values overriding earlier ones:

1. Built-in defaults
2. Global config: ~/.pi/agent/pact.json
3. Trusted project config: .pi/pact.json
4. Environment variables
5. Session-local setting commands such as /pact:on and /pact:fraction

Example pact.json:

{
  "enabled": true,
  "fraction": "80%",
  "threshold": "60%",
  "debug": false,
  "debugFile": null
}

Settings:

• enabled — enable automatic Pact compaction, default true
• fraction — fraction or percentage of eligible tool results to remove from live context by summarizing, default 80%
• threshold — token count or percentage like 60%, default 60%
• debug — enable context order notifications, default false
• debugFile — append debug records to the given JSONL file, default null

Environment variable overrides:

• PACT_ENABLED=1|0|true|false
• PACT_FRACTION=80% or PACT_FRACTION=0.8
• PACT_THRESHOLD=60% or PACT_THRESHOLD=160000
• PACT_DEBUG=1|0|true|false
• PACT_DEBUG_FILE=/tmp/pact.jsonl

Slash commands:

/pact                  manually trigger compaction
/pact:on               enable automatic Pact compaction
/pact:off              disable automatic Pact compaction
/pact:toggle           toggle automatic Pact compaction
/pact:status           show current Pact settings
/pact:stats            show Pact compaction stats
/pact:debug [on|off]   toggle or set context-order debug notifications
/pact:verify           verify compaction summary ordering
/pact:fraction N       set the fraction of eligible tool results to remove from live context
/pact:threshold N      set the token count or percent threshold
