📝 WalkthroughWalkthroughThe agent provisioning flow validates identifiers and configuration, executes scripts with separated arguments and a timeout, reads endpoint files asynchronously, and validates endpoint data. Unit tests cover success and failure paths. ChangesAgent provisioning hardening
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change hardens agent provisioning, but endpoint files containing JSON null can still produce an uncontrolled configuration error instead of a clear validation failure. This is a bounded, mergeable issue requiring owner follow-up. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 115-119: Update the CONTROLLER_ENDPOINT validation in the
endpoint-parsing method to require a string with non-zero length, rejecting
objects, numbers, arrays, empty strings, and other invalid values before
returning. Preserve the existing missing-endpoint error path and return
parsedEndpoint.CONTROLLER_ENDPOINT only after validation succeeds.
- Around line 76-98: Wrap the execFileAsync invocation in the provisioning flow
with a local rejection handler that discards captured stdout and stderr, then
throws a fixed sanitized error for the outer catch and logger.error path.
Preserve the existing command arguments and timeout options, and add a
regression test covering a failed script whose stdout and stderr contain secret
values, verifying those values are not logged.
- Around line 138-141: Update assertSafeFileIdentifier to first reject values
whose runtime type is not string, then apply SAFE_FILE_IDENTIFIER.test only to
valid strings; preserve the existing field-specific error behavior for all
unsafe or invalid identifier values.

@RinkalBhojani Thanks for your reply, I just signed all the commits, and fixed what coderabbitai reported, please take a look again. |

Nice cleanup of a genuinely nasty one — the argv-array switch kills the shell injection from #1707 outright, identifier validation closes the path-traversal angle on the endpoint filename, and the old promise-that-never-rejects hang on script failure is fixed too. Verified the positional args still line up with start_agent.sh ($1–$27), tests pass locally (9/9), typecheck and lint clean.
One regression worth sorting before merge (first comment) — legit org names will now be rejected. Two smaller notes below.
