+### Release Updates (`update-release:`)
+
+Updates GitHub release descriptions with three operations: replace, append, or prepend content.
+
+```yaml wrap
+safe-outputs:
+  update-release:
+    max: 1                       # Optional: max releases (default: 1, max: 10)
+    target-repo: "owner/repo"    # Optional: cross-repository
+    github-token: ${{ secrets.CUSTOM_TOKEN }}  # Optional: custom token
+```
+
+**Operations:**
+- **replace** - Completely replaces the release body
+- **append** - Adds content to the end with separator and AI attribution
+- **prepend** - Adds content to the start with AI attribution and separator
+
+**Agent Output Format:**
+```jsonl
+{"type": "update_release", "tag": "v1.0.0", "operation": "replace", "body": "New content"}
+{"type": "update_release", "tag": "v2.0.0", "operation": "append", "body": "Additional notes"}
+{"type": "update_release", "operation": "prepend", "body": "Summary (tag inferred)"}
+```
+
+The `tag` field is optional when triggered by release events (automatically inferred from context). The workflow needs read access to releases; only the generated job receives write permissions.
+
+### No-Op Logging (`noop:`)
+
+Enabled by default with any safe-outputs configuration. Allows agents to produce human-visible completion messages when no actions are needed, ensuring workflows never complete silently.
+
+```yaml wrap
+safe-outputs:
+  create-issue:     # noop enabled automatically
+  noop: false       # Or explicitly disable
+  # noop:
+  #   max: 1        # Or configure max messages (default: 1)
+```
+
+**Agent Output Format:**
+```jsonl
+{"type": "noop", "message": "Analysis complete - no issues found"}
+{"type": "noop", "message": "No changes needed, code follows best practices"}
+```
+
+Messages are displayed in the workflow conclusion comment (when reaction configured) or step summary. This provides transparency and prevents confusion from silent workflow completion.
+
 ### Missing Tool Reporting (`missing-tool:`)
 
 Enabled by default with any safe-outputs configuration. Automatically detects and reports tools lacking permissions or unavailable functionality.

 The field accepts a string environment name that must match a configured environment in the repository.

+### Skip-If-Match Condition (`skip-if-match:`)
+
+Conditionally skip workflow execution when a GitHub search query has matches. Useful for preventing duplicate scheduled runs or waiting for prerequisites.
+
+```yaml wrap
+on:
+  schedule:
+    - cron: "0 13 * * 1-5"
+  skip-if-match: 'is:issue is:open in:title "[daily-report]"'
+```
+
+**How it works:**
+1. A pre-activation check runs the search query against the current repository
+2. If matches are found, the workflow is skipped (activation job returns false)
+3. The query is automatically scoped to the current repository
+
+**Common Use Cases:**
+
+Prevent duplicate scheduled reports:
+```yaml wrap
+on:
+  schedule:
+    - cron: "0 9 * * 1"
+  skip-if-match: 'is:issue is:open label:weekly-summary'
+```
+
+Wait for deployment PRs to close:
+```yaml wrap
+on:
+  workflow_dispatch:
+  skip-if-match: "is:pr is:open label:deployment"
+```
+
+Skip if processing queue is full:
+```yaml wrap
+on:
+  schedule:
+    - cron: "0 */6 * * *"
+  skip-if-match: "is:issue is:open label:needs-processing"
+```
+
+The search uses GitHub's issue/PR search API with efficient `per_page=1` query. Supports all standard GitHub search qualifiers (`is:`, `label:`, `in:title`, `author:`, etc.).
