+### Customizing Planning with Skills
+
+You can leverage [Agent Skills](./skills.md) to customize how Gemini CLI
+approaches planning for specific types of tasks. When a skill is activated
+during Plan Mode, its specialized instructions and procedural workflows will
+guide the research and design phases.
+
+For example:
+
+- A **"Database Migration"** skill could ensure the plan includes data safety
+  checks and rollback strategies.
+- A **"Security Audit"** skill could prompt the agent to look for specific
+  vulnerabilities during codebase exploration.
+- A **"Frontend Design"** skill could guide the agent to use specific UI
+  components and accessibility standards in its proposal.
+
+To use a skill in Plan Mode, you can explicitly ask the agent to "use the
+[skill-name] skill to plan..." or the agent may autonomously activate it based
+on the task description.
+
+### Customizing Policies
+
+Plan Mode is designed to be read-only by default to ensure safety during the
+research phase. However, you may occasionally need to allow specific tools to
+assist in your planning.
+
+Because user policies (Tier 2) have a higher base priority than built-in
+policies (Tier 1), you can override Plan Mode's default restrictions by creating
+a rule in your `~/.gemini/policies/` directory.
+
+#### Example: Allow `git status` and `git diff` in Plan Mode
+
+This rule allows you to check the repository status and see changes while in
+Plan Mode.
+
+`~/.gemini/policies/git-research.toml`
+
+```toml
+[[rule]]
+toolName = "run_shell_command"
+commandPrefix = ["git status", "git diff"]
+decision = "allow"
+priority = 100
+modes = ["plan"]
+```
+
+#### Example: Enable research sub-agents in Plan Mode
+
+You can enable [experimental research sub-agents] like `codebase_investigator`
+to help gather architecture details during the planning phase.
+
+`~/.gemini/policies/research-subagents.toml`
+
+```toml
+[[rule]]
+toolName = "codebase_investigator"
+decision = "allow"
+priority = 100
+modes = ["plan"]
+```
+
+Tell the agent it can use these tools in your prompt, for example: _"You can
+check ongoing changes in git."_
+
+For more information on how the policy engine works, see the [Policy Engine
+Guide].
