src/hooks/anthropic-context-window-limit-recovery/ — Multi-Strategy Context Recovery
Generated: 2026-03-02
OVERVIEW
31 files (~2232 LOC). Most complex hook. Recovers from context window limit errors via multiple strategies applied in sequence.
RECOVERY STRATEGIES (in priority order)
| Strategy | File | Mechanism |
|---|---|---|
| Empty content recovery | empty-content-recovery.ts |
Handle empty/null content blocks in messages |
| Deduplication | deduplication-recovery.ts |
Remove duplicate tool results from context |
| Target-token truncation | target-token-truncation.ts |
Truncate largest tool outputs to fit target ratio |
| Aggressive truncation | aggressive-truncation-strategy.ts |
Last-resort truncation with minimal output preservation |
| Summarize retry | summarize-retry-strategy.ts |
Compaction + summarization then retry |

PRUNING SYSTEM
pruning-*.ts files handle intelligent output pruning:
pruning-deduplication.ts— Remove duplicate content across tool resultspruning-tool-output-truncation.ts— Truncate oversized tool outputspruning-types.ts— Pruning-specific type definitions
SDK VARIANTS
empty-content-recovery-sdk.ts and tool-result-storage-sdk.ts provide SDK-based implementations for OpenCode client interactions.
