 ### Step 1: Detect Project Configuration
 
 1. Check for `.releaserc.yml` (optional config override)
+   - If present, inspect whether it defines release hooks
 2. Auto-detect version file by scanning (priority order):

+**Project Hook Contract**:
+
+If `.releaserc.yml` defines `release.hooks`, keep the release workflow generic and delegate project-specific packaging/publishing to those hooks.
+
+Supported hooks:
+
+| Hook | Purpose | Expected Responsibility |
+|------|---------|-------------------------|
+| `prepare_artifact` | Build a releasable artifact for one target | Vendor local deps, rewrite package metadata, stage files |
+| `publish_artifact` | Publish one prepared artifact | Upload artifact, attach version/changelog/tags |
+
+Supported placeholders:
+
+| Placeholder | Meaning |
+|-------------|---------|
+| `{project_root}` | Absolute path to repository root |
+| `{target}` | Absolute path to the module/skill being released |
+| `{artifact_dir}` | Absolute path to a temporary artifact directory for this target |
+| `{version}` | Version selected by the release workflow |
+| `{dry_run}` | `true` or `false` |
+| `{release_notes_file}` | Absolute path to a UTF-8 file containing release notes/changelog text |
+
+Execution rules:
+- Keep the skill generic: do not hardcode registry/package-manager/project layout details into this SKILL.
+- If `prepare_artifact` exists, run it once per target before publish-related checks that need the final artifact.
+- Write release notes to a temp file and pass that file path to `publish_artifact`; do not inline multiline changelog text into shell commands.
+- If hooks are absent, fall back to the default project-agnostic release workflow.
+
 **Language Detection Rules**:
 
 Changelog files follow the pattern `CHANGELOG_{LANG}.md` or `CHANGELOG.{lang}.md`, where `{lang}` / `{LANG}` is a language or region code.
