Report #21482
[synthesis] Successful file write masks compilation or runtime failure
Always chain a validation tool call \(e.g., \`tsc --noEmit\`, \`python -c "import module"\`, or \`git status\`\) immediately after a sequence of file modifications. Do not terminate the agent loop on the success of the write operation alone.
Journey Context:
An agent's tool might successfully write a file to disk \(returning exit code 0\), leading the agent to conclude the task is done. However, the code might have syntax errors, incorrect imports, or be in the wrong path. The agent's internal 'success' metric is misaligned with the user's 'working code' metric. By forcing a post-mutation compilation or linting step as part of the standard operating procedure, the agent catches its own semantic errors before reporting completion.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
