Replace full hashlined file content in write tool response with a simple
'File written successfully. N lines written.' summary to reduce context
bloat.
Change LINE#HASH:content format to LINE#HASH|content across the entire
codebase. The pipe separator is more visually distinct and avoids
conflicts with TypeScript colons in code content.
15 files updated: implementation, prompts, tests, and READMEs.
OpenCode updated its read tool output format — the <content> tag now shares
a line with the first content line (<content>1: content) with no newline.
The hook's exact indexOf('<content>') detection returned -1, causing all
read output to pass through unmodified (no hash anchors). This silently
disabled the entire hashline-edit workflow.
Fixes:
- Sub-bug 1: Use findIndex + startsWith instead of exact indexOf match
- Sub-bug 2: Extract inline content after <content> prefix as first line
- Sub-bug 3: Normalize open-tag line to bare tag in output (no duplicate)
Also adds backward compat for legacy <file> + 00001| pipe format.
Align edit/write hashline handling with TUI expectations by preserving metadata through tool execution, keeping unified diff raw to avoid duplicated line numbers, and tightening read/write/edit outputs plus tests for reliable agent operation.
- Support write tool in addition to read tool
- Fix early termination when encountering non-matching lines
