+> **Exit code 2 for explicit denial** *(v1.0.70+)*: `preToolUse` hooks that exit with code `2` explicitly deny the tool call. Using exit code `2` is the recommended way to signal a deliberate policy block (as opposed to exit code `1`, which signals an unexpected script error). Both non-zero exit codes block the tool, but exit code `2` produces a cleaner, more informative denial message in the timeline.

 ### Modifying Tool Arguments with preToolUse
 
 Beyond approve/deny, `preToolUse` hooks can also **modify tool arguments** before they are passed to the tool, and inject **additional context** into the agent's reasoning. To do this, write JSON to stdout from your hook script:

+**Repository-pinned settings via `.github/copilot/settings.json`** *(v1.0.70+)*: A trusted repository can pin the model, reasoning effort level, and context tier for all sessions in that repository, and extend the URL, MCP server, and skill deny lists, by committing a `.github/copilot/settings.json` file:
+
+```json

+  "model": "claude-sonnet-4.6",

+
+When this file is present, the CLI applies these settings for any session rooted in the repository. This is useful for enforcing consistent AI settings across a team — for example, requiring a specific model for compliance workflows or capping effort level to control costs. The deny lists extend (not replace) your personal deny list configuration.

 > **Important (v1.0.36+)**: Custom agents, skills, and commands placed in `~/.claude/` (the Claude Code user directory) are **no longer loaded** by GitHub Copilot CLI. Only `~/.claude/settings.json` is read for configuration. If you previously stored personal agents or skills in `~/.claude/`, move them to the supported locations: `~/.copilot/agents/` for user-level agents, `~/.copilot/skills/` or `~/.agents/skills/` for personal skills, or `.github/agents/` and `.github/skills/` in your repositories for project-level customizations.

+**Q: What is Forge and how does it create skills automatically?**
+
+A: In v1.0.70+, Forge is the CLI's workflow pattern detector. When the CLI observes that you or an agent are repeatedly following a clear workflow pattern — a sequence of steps that keeps recurring across prompts — it automatically creates a **draft skill** capturing that pattern. You then review and approve it with `/chronicle skills review` before it is saved. This makes growing your skill library feel organic: instead of manually authoring skills from scratch, Forge surfaces them from work you are already doing.

+**`/plugins` dashboard** *(v1.0.69+)*: Inside a Copilot CLI session, run `/plugins` to open an interactive dashboard that shows all installed plugins, their status, and quick actions to enable, disable, or manage them — without leaving your current conversation:
+
+```
+/plugins

+
+The dashboard is also accessible while the agent is working, so you can inspect or toggle plugins mid-turn. You can also reload installed plugin extensions without restarting the session *(v1.0.69+)*.
+
+**Pinning a plugin to a specific commit SHA** *(v1.0.70+)*: Marketplace plugins can be pinned to an exact commit SHA for reproducible, auditable installations. Add a `sha` field to the plugin source configuration in your plugin settings to lock the plugin to that exact revision:
+
+```json
+{
+  "plugins": {
+    "my-plugin": {
+      "source": "awesome-copilot",
+      "sha": "abc1234def5678..."
+    }
+  }
+}
+```
+
+Pinning to a SHA prevents automatic updates from changing plugin behavior unexpectedly — useful in compliance-sensitive or production environments where you want explicit control over plugin versions.
