Pull request overview
This PR migrates the GitHub Action codebase from legacy JavaScript to TypeScript, introducing a TypeScript build/typecheck workflow and updating dependencies to support the new build pipeline.
Changes:
- Added
tsconfig.jsonand anesbuildbuild script to bundlesrc/index.tsintodist/index.js. - Converted the action entrypoint to TypeScript and removed the legacy
utils.js. - Updated npm dependencies/devDependencies and ignored intermediate TypeScript build output.

| src/index.ts | Converts action implementation to TypeScript and updates runtime behavior accordingly. |
| package.json | Switches build script to esbuild, adds typecheck script, updates dependencies. |
| package-lock.json | Locks updated dependency graph for the new toolchain and action libraries. |
| esbuild.config.mjs | Adds bundling configuration to produce dist/index.js for the action runtime. |
| .gitignore | Ignores intermediate build/ TypeScript output. |

src/index.ts:88
process.env.RUNNER_TEMP || ""can causeoutputPathto resolve relative to the current working directory when RUNNER_TEMP is unset, which can write the results file into an unexpected location (and may later fail when trying to read it back). Prefer failing fast with a clear error when RUNNER_TEMP is missing, or falling back toos.tmpdir()explicitly.
src/index.ts:104compiledCommandis built as a single string with unquoted user-provided paths (e.g.config,input,outputPath). If any of these contain spaces,@actions/execwill split them into multiple arguments and Doc Detective will receive corrupted flags. Consider callingexec("npx", [dd, ...args])(or at least quoting/escaping) so paths are passed as discrete args.
src/index.ts:145- The
working_directoryinput is passed ascwdto Doc Detective, but the subsequent git change detection usesexecSync("git status")without settingcwd(orprocess.chdir). Ifworking_directoryis not.this will check the wrong directory/repo (and can incorrectly skip/trigger PR creation). Run these git commands with the samecwdas the Doc Detective invocation.
src/index.ts:266 createPullRequest()runs all git commands (rev-parse,checkout,add,commit,push) without specifyingcwd, so it will operate on whatever the process working directory is rather than theworking_directoryinput used earlier. This can break PR creation for workflows that run Doc Detective in a subdirectory. Passcwdintoexec/execSync(orprocess.chdir) consistently.
src/index.ts:317- In the error handler for adding labels/assignees/reviewers, non-403 errors are logged but not propagated. That means API failures (e.g. invalid labels/reviewers) will silently succeed and the workflow will continue as if the PR was fully configured. Consider rethrowing the error (or at least failing the action) for unexpected statuses so misconfiguration is surfaced.

287-289:⚠️ Potential issue | 🟡 MinorMissing filter for empty labels, assignees, and reviewers.
Unlike
createIssue(lines 198-199), this function doesn't filter out empty strings after splitting. If inputs are empty or have trailing commas, this could send invalid values to the GitHub API.🐛 Suggested fix

In `@src/index.ts`:
- Around line 85-88: The outputPath resolution uses an empty string fallback for
RUNNER_TEMP which can resolve to the CWD; update the outputPath assignment (the
const outputPath variable using path.resolve) to use a safe fallback like
os.tmpdir() when process.env.RUNNER_TEMP is undefined or empty (import os via
require('os') or import { tmpdir } from 'os'), e.g. use process.env.RUNNER_TEMP
|| os.tmpdir() in the path.resolve call so the file is placed in the system temp
directory instead of the working directory.
