GOAL

Replace the 'Successfully wrote xxx bytes to xxx' result text shown for write tool calls with a syntax-highlighted code block rendering the actual file content.

  1. Prompt · +0
    Don't show 'Successfully wrote xxx bytes to xxx'; instead render a syntax-highlighted code block of the written file
  2. Agent did · +0m
    Searched the codebase for existing tool block rendering logic, read toolBlock.ts, ChatTranscript.vue, transcript.ts, HighlightedCode.vue and codeHighlight.ts to understand how tool results are modeled and rendered
  3. Agent did · +0m
    Checked package.json files to understand build/test scripts for the web package and monorepo root
  4. Agent did · +2m
    Added buildToolDetailModel() in toolBlock.ts to classify tool details into diff/code/bash/text/empty, and updated toolBlock.test.ts with new tests for write details
  5. Agent did · +2m
    Updated ChatTranscript.vue to use the new detail model with a cache, wired write blocks to render via HighlightedCode like read blocks, and added an empty-file state
  6. Fail · +3m
    Grep for toolBlockTextResult/toolBlockDiff usages returned no output, exiting with code 1, indicating leftover references may have been missed
  7. Agent did · +3m
    Re-read toolBlock.ts and the relevant ChatTranscript.vue sections to confirm the refactor was consistent and no stale references remained
  8. Agent did · +3m
    Ran the toolBlock test suite, built the web package, and checked git status to confirm only the intended three files were modified
  9. Outcome · +4m
    Write tool details now render via HighlightedCode with file-path-based syntax highlighting; added regression test verifying write details use file content not success text; build passed and tests passed
VERDICT

Next time I'd point directly at toolBlock.ts and ChatTranscript.vue upfront since I already knew roughly where tool rendering logic lived, instead of letting the agent grep broadly first. The build and test run at the end did the real work of confirming the refactor was safe, since the agent's own grep check for stale references came back empty and needed a manual re-read to double check.
