In @.github/actions/agent-scan/action.yml:
- Around line 8-12: The action.yml declares outputs pr-number and pr-title but
the action implementation (index.ts) never sets them; update index.ts to extract
the PR number and title from the GitHub context (e.g.,
context.payload.pull_request?.number and context.payload.pull_request?.title)
and call core.setOutput('pr-number', String(prNumber)) and
core.setOutput('pr-title', prTitle) when available (or remove the outputs from
action.yml if you decide they are not needed).
In @.github/actions/agent-scan/index.ts:
- Line 23: The core.info call logs user.name which may be null; update the
logging to safely handle null by using a fallback (e.g., prefer user.name, then
user.login, then a literal like 'unknown') so the message never contains "null";
modify the expression used in the core.info invocation (referencing user.name
and user.login and the core.info call in index.ts) to select the first
non-null/non-empty value before interpolating into the string.
- Around line 25-29: The catch block currently only handles Error instances and
silently ignores other thrown values; update the catch for catch (error:
unknown) to ensure all thrown values call core.setFailed by formatting non-Error
throws (e.g., convert to string or JSON for objects) and include that formatted
text in the core.setFailed call so failures like thrown strings or plain objects
are reported; reference the existing catch (error: unknown) and core.setFailed
usage to locate and change the behavior.
In @.github/actions/agent-scan/package.json:
- Line 10: Replace the "tsdown": "latest" entry in package.json with a pinned
semver (e.g., "tsdown": "0.x.y") instead of "latest"; choose the exact version
your build currently uses (check package-lock.json or run npm view tsdown
versions or npm ls tsdown to determine the working version), update package.json
with that version, run npm install to refresh package-lock.json, and commit both
package.json and the updated lockfile so the action has reproducible builds.

Non-Error exceptions are silently swallowed.
If a non-Error value is thrown (e.g., a string or object), the catch block does nothing and the action completes successfully despite the failure.

🧩 Analysis chain
🌐 Web query:
tsdown npm latest version 2026
💡 Result:
As of March 11, 2026, the latest published version of the tsdown npm package is 0.21.0 (published March 10, 2026). [1][2]
Recent prereleases shown include 0.21.0-beta.5 (also published March 10, 2026). [1]
Check yourself:
npm view tsdown versionPin tsdown to a specific version for reproducible builds.
Using "latest" means builds may behave differently over time as tsdown receives updates, potentially breaking the action unexpectedly. Pin to a specific version compatible with your current setup.
Proposed fix

- "tsdown": "latest",
+ "tsdown": "^0.21.0",
"typescript": "^5.3.0"

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

29-30: Avoidanytypes for better type safety.Using
anyforuserandeventsloses type safety and IDE support. Consider using proper types from the Octokit response or defining explicit interfaces.💡 Suggested improvement
- let user: any; - let events: any; + let user: Awaited<ReturnType<typeof octokit.rest.users.getByUsername>>["data"]; + let events: Awaited<ReturnType<typeof octokit.rest.activity.listPublicEventsForUser>>["data"];Alternatively, define explicit interfaces matching the cached data structure.

35-36: Consider importingfsonce at the top of the function.The

In @.github/actions/agent-scan/index.ts:
- Line 10: The import for the VerifiedAutomation type in
.github/actions/agent-scan/index.ts contains a stray double slash; update the
import path from "../../..//shared/types/automation" to
"../../../shared/types/automation" (the import statement that references
VerifiedAutomation) so the module resolves correctly.
