+# Agent Integration Guide
+
+This guide is for agentic coding partners that need to integrate the composite actions published by this repository.
+
+## Source Of Truth
+
+Pin all action references to a released tag (for example `@v0.2.0`) and keep all vociferate references on the same tag in a workflow.
+
+Published composite actions:
+
+- `git.hrafn.xyz/aether/vociferate@v0.2.0` (root action)
+- `git.hrafn.xyz/aether/vociferate/prepare@v0.2.0`
+- `git.hrafn.xyz/aether/vociferate/publish@v0.2.0`
+- `git.hrafn.xyz/aether/vociferate/coverage-badge@v0.2.0`
+
+## Action Selection Matrix
+
+Use this when deciding which action to call:
+
+- Choose `prepare` when you need to update changelog/version files, commit, and push a release tag.
+- Choose `publish` when a tag already exists and you need to create or update release notes/assets.
+- Choose `coverage-badge` after tests have produced `coverage.out` and you need coverage artefacts uploaded.
+- Choose root `vociferate` for direct recommend/prepare logic without commit/tag/push behavior.
+
+## Preconditions
+
+Apply these checks before invoking actions:
+
+- Checkout repository first.
+- For prepare/publish flows that depend on tags/history, use full history checkout (`fetch-depth: 0`).
+- Use valid credentials in `github.token` (or explicit token input for `publish` when needed).
+- Set required vars/secrets for coverage uploads:
+  - `vars.ARTEFACT_BUCKET_NAME`
+  - `vars.ARTEFACT_BUCKET_ENDPONT`
+  - `secrets.ARTEFACT_BUCKET_WRITE_ACCESS_KEY`
+  - `secrets.ARTEFACT_BUCKET_WRITE_ACCESS_SECRET`
+- For externally visible changelog links, set `vars.VOCIFERATE_REPOSITORY_URL` to the server/base URL only.
+
+## Changelog Format Guidance
+
+Agents should keep `CHANGELOG.md` in a Keep a Changelog compatible structure because vociferate derives versions and release notes from headings.
+
+Required conventions:
+
+- Keep the top-level heading as `# Changelog`.
+- Maintain an `## [Unreleased]` section.
+- Keep the standard subsections under `Unreleased` in this order:
+  - `### Breaking`
+  - `### Added`
+  - `### Changed`
+  - `### Removed`
+  - `### Fixed`
+- Record releases with headings like `## [1.2.3] - YYYY-MM-DD`.
+- Use bullet entries under subsections (for example `- Added new publish output`).
+- Preserve or regenerate bottom reference links (`[Unreleased]: ...`, `[1.2.3]: ...`) instead of mixing inline heading links.
+
+Semver behavior used by recommendation logic:
+
+- `Breaking` or `Removed` entries trigger a major bump.
+- `Added` entries trigger a minor bump.
+- Otherwise recommendation falls back to a patch bump.
+

+```markdown
+# Changelog
+
+## [Unreleased]
+
+### Breaking
+
+### Added
+
+### Changed
+
+### Removed
+
+### Fixed
+```
+
+## Minimal Integration Patterns
+
+### 1. Prepare Then Publish
+
+```yaml
+jobs:
+  prepare:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          fetch-depth: 0
+      - id: prepare
+        uses: git.hrafn.xyz/aether/vociferate/prepare@v0.2.0
+
+  publish:
+    needs: prepare
+    uses: aether/vociferate/.gitea/workflows/do-release.yml@v0.2.0
+    with:
+      tag: ${{ needs.prepare.outputs.version }}
+    secrets: inherit
+```
+
+### 2. Publish Existing Tag
+
+```yaml
+jobs:
+  release:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          fetch-depth: 0
+      - id: publish
+        uses: git.hrafn.xyz/aether/vociferate/publish@v0.2.0
+        with:
+          version: v1.2.3
+```
+
+### 3. Coverage Badge Publication
+
+```yaml
+jobs:
+  coverage:
+    runs-on: ubuntu-latest
+    env:
+      AWS_ACCESS_KEY_ID: ${{ secrets.ARTEFACT_BUCKET_WRITE_ACCESS_KEY }}
+      AWS_SECRET_ACCESS_KEY: ${{ secrets.ARTEFACT_BUCKET_WRITE_ACCESS_SECRET }}
+      AWS_DEFAULT_REGION: ${{ vars.ARTEFACT_BUCKET_REGION }}
+      AWS_EC2_METADATA_DISABLED: true
+    steps:
+      - uses: actions/checkout@v4
+      - name: Run tests with coverage
+        run: go test -covermode=atomic -coverprofile=coverage.out ./...
+      - id: badge
+        uses: git.hrafn.xyz/aether/vociferate/coverage-badge@v0.2.0
+        with:
+          artefact-bucket-name: ${{ vars.ARTEFACT_BUCKET_NAME }}
+          artefact-bucket-endpoint: ${{ vars.ARTEFACT_BUCKET_ENDPONT }}
+```

+## Inputs And Outputs Cheatsheet
+
+### prepare
+
+Common inputs:
+
+- `version` (optional override)
+- `version-file` (optional)
+- `version-pattern` (optional)
+- `changelog` (optional)
+
+Primary output:
+
+- `version` (resolved tag, for example `v1.2.3`)
+
+### publish
+
+Common inputs:
+
+- `token` (optional, defaults to workflow token)
+- `version` (optional if running from tag ref)
+- `changelog` (optional)
+
+Primary outputs:
+
+- `release-id`
+- `tag`
+- `version`
+
+### coverage-badge
+
+Required inputs:
+
+- `artefact-bucket-name`
+- `artefact-bucket-endpoint`
+
+Useful optional inputs:
+
+- `coverage-profile` (default `coverage.out`)
+- `summary-file` (append markdown summary)
+
+Primary outputs:
+
+- `total`
+- `report-url`
+- `badge-url`
+
+## Guardrails For Agents
+
+Use these rules to avoid common automation mistakes:
+
+- Do not mix action tags in one workflow update.
+- Do not assume a release workflow will run from a tag push in all environments; reusable workflow call paths are supported.
+- Do not treat `VOCIFERATE_REPOSITORY_URL` as a full repository URL; it must be a base URL.
+- Keep displayed URLs protocol-relative (`//`) when writing markdown/browser-facing outputs.
+- If a workflow environment does not support `GITHUB_STEP_SUMMARY`, append markdown to a file and print it in a final `Summary` step.
