+# Copilot Coding Agent Instructions
+
+Trust these instructions. Only search the codebase if information here is incomplete or found to be in error.
+
+## Repository Overview
+
+**dependency-review-action** is a GitHub Action (TypeScript/Node.js 20) that scans pull requests for dependency changes, raising errors for vulnerabilities or invalid licenses. It queries the GitHub Dependency Review API, evaluates changes against configured rules, and produces job summaries and PR comments. The action entry point is `dist/index.js` (bundled via `ncc`). The repo is small (~15 source files, ~15 test files).
+
+## Build & Validation Commands
+
+For CI-parity installs and local validation, run `npm ci --ignore-scripts` before other commands. This is the install step used in CI; release workflows may follow different install instructions (see CONTRIBUTING).
+
+| Task         | Command                   | Notes                                                                                                                                    |
+| ------------ | ------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- |
+| Install      | `npm ci --ignore-scripts` | ~45s. Use `--ignore-scripts` for CI-parity installs; release workflows may use `npm i` per CONTRIBUTING.                                 |
+| Build        | `npm run build`           | Compiles `src/*.ts` → `lib/*.js` via `tsc -p tsconfig.build.json`. ~5s.                                                                  |
+| Test         | `npm test`                | Runs Jest. ~8s. All tests should pass.                                                                                                   |
+| Lint         | `npm run lint`            | ESLint on `src/**/*.ts`. Ignore the TS version warning—it still passes.                                                                  |
+| Format check | `npm run format-check`    | Prettier check on `**/*.ts`.                                                                                                             |
+| Format fix   | `npm run format`          | Auto-fix formatting with Prettier.                                                                                                       |
+| Package      | `npm run package`         | Bundles the action entrypoint (`package.json#main`) → `dist/index.js` via `ncc`. ~7s. Do NOT include `dist/` changes in non-release PRs. |
+| All          | `npm run all`             | Runs: build → format → lint → package → test (in that order).                                                                            |
+
+### Validation Sequence After Making Changes
+
+Always run these commands in this order to validate changes:
+
+```sh
+npm run build
+npm run format-check
+npm run lint
+npm test
+```
+
+If format-check fails, run `npm run format` to auto-fix, then re-check.
+
+### CI Checks (`.github/workflows/ci.yml`)
+
+CI runs on PRs (excluding `**.md` changes) with Node 20:
+
+1. **test** job: `npm ci --ignore-scripts` → `npm test`
+2. **lint** job: `npm ci --ignore-scripts` → `npm run format-check` → `npm run lint`
+
+Additional workflows: `dependency-review.yml` (self-test), `codeql.yml` (CodeQL analysis), `stale.yaml` (stale issues).

+### Configuration Files
+
+| File                  | Purpose                                                                      |
+| --------------------- | ---------------------------------------------------------------------------- |
+| `tsconfig.json`       | Base TypeScript config (ES6 target, CommonJS, strict mode)                   |
+| `tsconfig.build.json` | Build config — extends base, includes only `src/`, outputs to `lib/`         |
+| `jest.config.js`      | Jest config — uses `ts-jest`, matches `**/*.test.ts`                         |
+| `.eslintrc.json`      | ESLint — `plugin:github/recommended`, strict TS rules, no semicolons         |
+| `.prettierrc.json`    | Prettier — no semis, single quotes, no bracket spacing, trailing comma: none |
+| `.prettierignore`     | Ignores `dist/`, `lib/`, `node_modules/`                                     |
+
+### Key TypeScript/Style Rules
+
+- No semicolons (enforced by ESLint and Prettier)
+- Single quotes, no trailing commas
+- `@typescript-eslint/no-explicit-any: error` — never use `any`
+- `@typescript-eslint/explicit-function-return-type: error` — all functions need return types (expressions exempt)
+- Unused function parameters/args must be prefixed with `_` (e.g. `_unused`); unused variables should be removed
+- Use Zod schemas (in `src/schemas.ts`) for all data validation and type definitions
+- Config option defaults belong in Zod schemas, NOT in `action.yml`
+
+### Testing Patterns
+
+- Tests use Jest with `ts-jest` transform — no build step needed before running tests
+- Use `__tests__/test-helpers.ts` `setInput(name, value)` to mock action inputs (sets `INPUT_*` env vars)
+- Use `__tests__/fixtures/create-test-change.ts` and `create-test-vulnerability.ts` for test data factories
+- Test files follow `__tests__/<module>.test.ts` naming convention
+- Tests run directly against TypeScript source (not compiled JS)
+
+### Important Notes
+
+- The action runs on `node20` (declared in `action.yml`)
+- Source imports often use relative `../src/` paths (e.g. `import {readConfig} from '../src/config'`)
+- Adding a new action input requires changes in: `action.yml` (input definition), `src/schemas.ts` (Zod schema with default), `src/config.ts` (reading the input), and relevant source/test files
+- `dist/index.js` is committed for GitHub Actions but PR contributors should NOT include `dist/` changes — maintainers handle rebuilding
+- The `lib/` directory is gitignored
+- Scorecard tests make real HTTP calls to `api.securityscorecards.dev` and `deps.dev`

-### How it works
+## Bug reports and other issues
 
-This Action makes an authenticated query to the Dependency Graph Diff
-API endpoint (`GET /repos/{owner}/{repo}/dependency-graph/compare/{basehead}`)
-to find out the set of added and removed dependencies for each manifest.
+If you've encountered a problem, please let us know by [submitting an issue](https://github.com/actions/dependency-review-action/issues/new)!
 
-### Bootstrapping the project
+## Enhancements and feature requests
 
-```
-git clone https://github.com/actions/dependency-review-action.git
-cd dependency-review-action
-npm install
-```
+If you've got an idea for a new feature or a significant change to the code or its dependencies, please submit as [an issue](https://github.com/actions/dependency-review-action/issues/new) so that the community can see it, and we can discuss it there. We may not be able to respond to every single issue, but will make a best effort!
 
-### Running the tests
+If you'd like to make a contribution yourself, we ask that before significant effort is put into code changes, that we have agreement that the change aligns with our strategy for the action. Since this is a verified Action owned by GitHub we want to make sure that contributions are high quality, and that they maintain consistency with the rest of the action's behavior.
 
-```
-npm run test
-```
+1. Create an [issue discussing the idea](https://github.com/actions/dependency-review-action/issues/new), so that we can discuss it there.
+2. If we agree to incorporate the idea into the action, please write-up a high level summary of the approach that you plan to take so we can review
 
-_Note_: We don't have any useful tests yet, contributions are welcome!
+## Stalebot
 
-## Local Development
+We have begun using a [Stalebot action](https://github.com/actions/stale) to help keep the Issues and Pull requests backlogs tidy. You can see [the configuration](.github/workflows/stalebot.yml). If you'd like to keep an issue open after getting a stalebot warning, simply comment on it and it'll reset the clock.
 
-It is recommended to have atleast [Node 18](https://nodejs.org/en/) installed.
-We have a script to scan a given PR for vulnerabilities, this will

+Ready to contribute to `dependency-review-action`? Here is some information to help you get started.
+
+### High level overview of the action
+
+This action makes an authenticated query to the [Dependency Review API](https://docs.github.com/en/rest/dependency-graph/dependency-review) endpoint (`GET /repos/{owner}/{repo}/dependency-graph/compare/{basehead}`) to find out the set of added and removed dependencies for each manifest.
+
+The action then evaluates the differences between the pushes based on the rules defined in the action configuration, and summarizes the differences and any violations of the rules you have defined as a comment in the pull request that triggered it and the action outputs.
+
+### Local Development
+
+Before you begin, you need to have [Node.js](https://nodejs.org/en/) installed, minimum version 20.
+
+#### Bootstrapping the project

+1. Change to the working directory: `cd dependency-review-action`
+2. Install the dependencies: `npm install`
+3. Make sure the tests pass on your machine: `npm run test`
+
+#### Manually testing for vulnerabilities
+
+We have a script to scan a given PR for vulnerabilities, which will help you test your local changes. Make sure to [grab a Personal Access Token (PAT)](https://github.com/settings/tokens) before proceeding (you'll need `repo` permissions for private repos):

+You now have a tag and release using the semver version you used above. The last remaining thing to do is to update the major version branch to match the current release. This allows users to adopt a major version number (e.g. `v4`) in their workflows while automatically getting all the minor/patch updates.
+
+As of v4.8.3, we use a **branch** (not a force-pushed tag) for the major version pointer. This is important because force-pushing tags breaks GitHub's auto-generated release changelog links (see [#1035](https://github.com/actions/dependency-review-action/issues/1035)) and violates git's (unenforced) expectation that tags are immutable.
+
+To update the major version branch:
 
 ```
-git tag -fa v3 -m "Updating v3 to 3.0.1"
-git push origin v3 --force
+git checkout main
+git pull origin main
+git branch -f v4 HEAD
+git push origin v4
 ```

Create a token in [developer settings](https://github.com/settings/tokens). | Any token with `read` permissions to the repository hosting the config file.                                                         |
+#### Option 1: Using inline configuration
 
-#### Example
+You can pass configuration options to the dependency review action using your workflow file.
 
-Start by specifying that you will be using an external configuration file:
+1. In the same YAML workflow file you created during installation, use the `with:` key to specify your chosen settings:
 
-```yaml
-- name: Dependency Review
-  uses: actions/dependency-review-action@v2
-  with:
-    config-file: './.github/dependency-review-config.yml'
-```
+   ```yaml
+   name: 'Dependency Review'
+   on: [pull_request]
+   permissions:
+     contents: read
+   jobs:
+     dependency-review:
+       runs-on: ubuntu-latest
+       steps:
+         - name: 'Checkout Repository'
+           uses: actions/checkout@v4
+         - name: Dependency Review
+           uses: actions/dependency-review-action@v4
+           with:
+             fail-on-severity: moderate
 
-And then create the file in the path you just specified. Please note
-that the **option names in external files use underscores instead of dashes**:
+             # Use comma-separated names to pass list arguments:
+             deny-licenses: LGPL-2.0, BSD-2-Clause
+             allow-dependencies-licenses: "pkg:npm/@myorg/mypackage, pkg:npm/packagename, pkg:githubactions/owner/repo@2.0.0"
+   ```
 
-```yaml
-fail_on_severity: 'critical'
-allow_licenses:
-  - 'GPL-3.0'
-  - 'BSD-3-Clause'
-  - 'MIT'
-```
+#### Option 2: Using an external configuration file
 
-For more examples of how to use this action and its configuration options, see the [examples](docs/examples.md) page.
+You can use an external configuration file to specify settings for this action. The file can be a local file or a file in an external repository.
 
-### Considerations
+1. In the same YAML workflow file you created during installation, use `config-file` to specify that you are using an external configuration file.
 
-- Checking for licenses is not supported on Enterprise Server as the API does not return license information.
-- The action will only accept one of the two `license` parameters; an error will be raised if you provide both.
-- We don't have license information for all of your dependents. If we can't detect the license for a dependency **we will inform you, but the action won't fail**.
+   ```yaml
+   name: 'Dependency Review'
+   on: [pull_request]
+   permissions:
+     contents: read
+   jobs:
+     dependency-review:
+       runs-on: ubuntu-latest
+       steps:
+         - name: 'Checkout Repository'
+           uses: actions/checkout@v4
+         - name: Dependency Review
+           uses: actions/dependency-review-action@v4
+           with:
+             config-file: './.github/dependency-review-config.yml'
+   ```
 
-## Blocking pull requests
+   | Option        | Usage                                                                                                                                        | Possible values                                                                                                                      |
+   | ------------- | -------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
+   | `config-file` | A path to a file in the current repository or an external repository. Use this syntax for external files: `OWNER/REPOSITORY/FILENAME@BRANCH` | **Local file**: `./.github/dependency-review-config.yml` <br> **External repo**: `github/octorepo/dependency-review-config.yml@main` |
 
-The Dependency Review GitHub Action check will only block a pull request from being merged if the repository owner has required the check to pass before merging. For more information, see the [documentation on protected branches](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/about-protected-branches#require-status-checks-before-merging).
+2. Optionally, if the file resides in a private external repository, and for all GitHub Enterprise Server repositories, use `external-repo-token` to specify a token for fetching the file.
+
+   ```yaml
+   - name: Dependency Review
+     uses: actions/dependency-review-action@v4
+     with:
+       config-file: 'github/octorepo/dependency-review-config.yml@main'
+       external-repo-token: 'ghp_123456789abcde'
+   ```
+
+   | Option                | Usage                                                                                                                                                                                                                                                     | Possible values                                                              |
+   | --------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------- |
+   | `external-repo-token` | Specifies a token for fetching the configuration file. It is required if the file resides in a private external repository and for all GitHub Enterprise Server repositories. Create a token in [developer settings](https://github.com/settings/tokens). | Any token with `read` permissions to the repository hosting the config file. |
+
+3. Create the configuration file in the path you specified for `config-file`.
+4. In the configuration file, specify your chosen settings.
+
+   ```yaml
+   fail-on-severity: 'critical'
+   allow-licenses:
+     - 'GPL-3.0'
+     - 'BSD-3-Clause'
+     - 'MIT'
+   ```
+
+#### `OTHER` in license strings
+
+License data comes from [ClearlyDefined](https://clearlydefined.io) and you may sometimes see licenses displayed with the string `OTHER` in them. ClearlyDefined [defines OTHER](https://docs.clearlydefined.io/docs/curation/curation-guidelines) as:
+
+> This indicates that a human confirmed that there is license information in the file but that the license is not an SPDX-identified license.
+
+`OTHER` is not a valid [SPDX license identifier](https://spdx.org/licenses/), so we convert `OTHER` in a license string into `LicenseRef-clearlydefined-OTHER`, which _is_ valid in SPDX. If you want to add that to the deny or allow list, be sure to add `LicenseRef-clearlydefined-OTHER` to this list, because that is what we'll actually be comparing.
+
+#### Further information
+
+- For more examples of how to use this action and its configuration options, see the [examples](docs/examples.md) page.
+- For general information about dependency review on GitHub, see "[About dependency review](https://docs.github.com/en/code-security/supply-chain-security/understanding-your-software-supply-chain/about-dependency-review)" in the GitHub Docs documentation.
+
+## Using dependency review action to block a pull request from being merged
+
+You can configure your repository to block a pull request from being merged if the pull request fails the dependency review action check. To do this, the repository owner must configure branch protection settings that require the check to pass before merging. For more information, see "[Require status checks before merging](https://docs.github.com/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/about-protected-branches#require-status-checks-before-merging)" in GitHub Docs documentation.
+
+## Outputs
+
+Dependency review action can create [outputs](https://docs.github.com/en/actions/using-jobs/defining-outputs-for-jobs), so that data from its execution can be used by other jobs in a workflow.
+
+- `comment-content` is generated with the same content as would be present in a Dependency Review Action comment.
+- `dependency-changes` holds all dependency changes in a JSON format. The following outputs are subsets of `dependency-changes` filtered based on the configuration:
+  - `vulnerable-changes` holds information about dependency changes with vulnerable dependencies in a JSON format.
+  - `invalid-license-changes` holds information about invalid or non-compliant license dependency changes in a JSON format.
+  - `denied-changes` holds information about denied dependency changes in a JSON format.
+
+> [!NOTE]
+> Action outputs are unicode strings [with a 1MB size limit](https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#outputs-for-docker-container-and-javascript-actions).
+>
+> If you use these outputs in a run-step, you must store the output data in an environment variable instead of using the output directly. Using an output directly might break shell scripts. For example:
+>
+> ```yaml
+> env:
+>   VULNERABLE_CHANGES: ${{ steps.review.outputs.vulnerable-changes }}
+> run: |
+>   echo "$VULNERABLE_CHANGES" | jq
+> ```
+>
+> instead of direct `echo '${{ steps.review.outputs.vulnerable-changes }}'`.
+> See [examples](docs/examples.md) for more.

 ## Exclude dependencies from their name or groups
 
-Using the `deny-packages` option you can exclude dependencies by their PURL. You can add multiple values separated by a commas.
+With the `deny-packages` option, you can exclude dependencies based on their PURL (Package URL). If a specific version is provided, the action will deny packages matching that version. When no version is specified, the action treats it as a wildcard, denying all matching packages regardless of version. Multiple values can be added, separated by commas.
+
 Using the `deny-groups` option you can exclude dependencies by their group name/namespace. You can add multiple values separated by a comma.
 
-In this example, we are excluding `pkg:maven/org.apache.logging.log4j:log4j-api` and `pkg:maven/org.apache.logging.log4j/log4j-core` from `maven` and all packages in the group `pkg:maven/com.bazaarvoice.maven`
+In this example, we are excluding all versions of `pkg:maven/org.apache.logging.log4j:log4j-api` and only `2.23.0` of log4j-core `pkg:maven/org.apache.logging.log4j/log4j-core@2.23.0` from `maven` and all packages in the group `pkg:maven/com.bazaarvoice.maven/`

+## Waiting for dependency submission jobs to complete
+
+When possible, this action will [include dependencies submitted through the dependency submission API][DSAPI]. In this case,
+it's important for the action not to complete until all of the relevant dependencies have been submitted for both the base
+and head commits.
+
+When this action runs before one or more of the dependency submission actions, there will be an unequal number of dependency
+snapshots between the base and head commits. For example, there may be one snapshot available for the tip of `main` and none
+for the PR branch. In that case, the API response will contain a "snapshot warning" explaining the discrepancy.
+
+In this example, when the action encounters one of these warnings it will retry every 10 seconds after that for 60 seconds
+or until there is no warning in the response.
