Session Compaction

Session compaction compresses conversation history into a summary, freeing context space for long conversations.

Manual Compaction

Use slash commands to compact on demand:

/compact
/summarize

Auto-Compaction

Pando automatically compacts when the context window fills up during an agent run:

AutoCompact = true

Per-agent configuration:

[Agents.coder]
AutoCompact = false
AutoCompactThreshold = 0.0

[Agents.summarizer]
Model = 'ollama.qwopus:latest'

How It Works

The Summarize method compresses conversation history
Messages before the summary are replaced by it
The summary is stored as a special message boundary
Context space is freed for new messages

Configuration

Setting	Description
`AutoCompact`	Global auto-compact toggle
`AutoCompactThreshold`	Context usage threshold to trigger (0.0 = automatic)
`[Agents.summarizer].Model`	Model used for summarization

When to Use

Long conversations approaching context limits
After completing a major task and starting a new one
When response quality degrades due to context noise

Compaction preserves the most important information while removing verbose tool outputs and intermediate steps. The summary captures key decisions, file changes, and progress.
