 # tas-actions
 
+Reusable GitHub Actions for [TAS (Tea Advanced Security)](https://github.com/go-gitea/gitea): upload SARIF reports and gate CI on the API response.
+
+## Actions
+
+### [tas-upload-sarif](tas-upload-sarif/)
+
+Uploads a SARIF report from a file to TAS and **fails the job** if the API returns `allowed: false`.
+
+**Example workflow** (e.g. after a security scan that produces SARIF):
+
+```yaml
+jobs:
+  scan:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+
+      # Run your scanner and produce SARIF (e.g. to results.sarif)
+      # - run: ./run-scanner --output results.sarif
+
+      - name: Upload SARIF to TAS and gate
+        uses: your-org/tas-actions/tas-upload-sarif@v1
+        with:
+          tas-base-url: 'https://tas.example.com'
+          sarif-file: 'results.sarif'
+```
+
+See [tas-upload-sarif/README.md](tas-upload-sarif/README.md) for all inputs and options.

+# TAS Upload SARIF
+
+Reusable GitHub Action that uploads a SARIF report to [TAS (Tea Advanced Security)](https://github.com/go-gitea/gitea) and **fails the job** if the API responds with `allowed: false` (e.g. new findings above your policy).
+
+## Inputs
+
+| Input          | Required | Description                                               |
+| -------------- | -------- | --------------------------------------------------------- |
+| `tas-base-url` | Yes      | Base URL of the TAS API (e.g. `https://tas.example.com`)  |
+| `sarif-file`   | Yes      | Path to the SARIF report file (JSON)                      |
+| `owner`        | No       | Repository owner (default: `github.repository_owner`)     |
+| `repo`         | No       | Repository name (default: `github.event.repository.name`) |
+| `branch`       | No       | Branch name (default: `github.ref_name`)                  |
+
+## Usage
+
+```yaml
+- name: Upload SARIF to TAS and gate
+  uses: https://gitea.t000-n.de/t.behrendt/tas-actions/tas-upload-sarif@v1
+  with:
+    tas-base-url: "https://tas.example.com"
+    sarif-file: "results.sarif"
+```
+
+With explicit owner/repo/branch (e.g. for monorepos or custom refs):
+
+```yaml
+- uses: [your-org/tas-actions/tas-upload-sarif@v1](https://gitea.t000-n.de/t.behrendt/tas-actions/tas-upload-sarif@v1)
+  with:
+    tas-base-url: ${{ vars.TAS_BASE_URL }}
+    sarif-file: 'scan-output.sarif'
+    owner: ${{ github.repository_owner}}
+    repo: ${{ github.event.repository.name }}
+    branch: ${{ github.head_ref }}
+```
+
+## Behavior
+
+1. **POST**s the SARIF file to `{tas-base-url}/repos/{owner}/{repo}/branches/{branch}/reports`.
+2. On HTTP non-200, the step fails and prints the response body.
+3. On success, reads the JSON response:
+   - If `allowed` is `true`, the step succeeds.
+   - If `allowed` is `false`, the step **fails** and prints `reason` and the full response (e.g. `new_critical`, `new_high`, `new_findings`).
+
+## Requirements
+
+- **GitHub-hosted runners**: `curl` and `jq` are available by default.
+- **Self-hosted runners**: ensure `curl` and `jq` are installed.
