…esholds ## Issues Addressed ### anomalyco#8140 - Configurable context limit and auto-compaction threshold Fixed by: - Add `compaction.threshold` config option in config.ts (0.5-0.99, default 0.9) - Add `compaction.maxContext` config option in config.ts to override model's context limit - Implement `shouldCompact()` function in compaction.ts with threshold logic ### anomalyco#8089 - Auto-compaction not preventing context_length_exceeded errors Fixed by: - Pre-check in prompt.ts: estimate tokens before API call, trigger compaction if threshold exceeded - Post-check in processor.ts: monitor context after tool execution - Add `getMaxBytes()` and `getMaxMetadata()` in truncation.ts for model-adaptive tool output limits - Update bash.ts, tool.ts, registry.ts to use dynamic limits based on model size ## Config Example ```json { "compaction": { "threshold": 0.8, "maxContext": 100000 } } ## Test Plan - 756 tests passing (+8 from baseline) - Added 22 new tests (truncation: 14, compaction: 8) - Type check passing

Fixes #8089, #8293, #6286, #6068
Closes #8140
What does this PR do?
Problem
Auto-compaction was not triggering before context limits were exceeded, causing
context_length_exceededAPI errors. Users had no control over when compaction triggered or ability to limit context usage for cost optimization.Solution
#8140 - Configurable context limit and auto-compaction threshold
compaction.thresholdconfig option (0.5-0.99, default 0.9)compaction.maxContextconfig option to override model's context limitshouldCompact()function in compaction.ts with threshold logic#8089, #8293, #6286, #6068 - Prevent context_length_exceeded errors
Config Example
{ "compaction": { "threshold": 0.8, "maxContext": 100000 } }How did you verify your code works?
