+          ## Instructions for the issue analysis agent
+
+          These scraping failures are **almost never timeouts**. They are
+          almost always caused by Liquid/Markdown corruptions in the
+          translated source that make the page fail to render. Please do not
+          file this as a transient/timeout issue.
+
+          To investigate:
+
+          1. Pull the translation repos locally:
+             \`\`\`
+             npm run clone-translations
+             \`\`\`
+          2. Identify the specific corruptions with the canonical reporter
+             (verify the exact script name in \`package.json\` before running):
+             \`\`\`
+             npm run count-translation-corruptions
+             \`\`\`
+             The script writes a structured JSON report to stdout listing each
+             corrupted file, its location, the error message, and the
+             offending/illegal tag token when available.
+          3. **Open a pull request that fixes the corruptions** rather than
+             just commenting the findings on this issue. The issue body above
+             already lists the affected pages; the value the agent adds is
+             the fix. Where possible, fix the underlying pattern in
+             \`src/languages/lib/correct-translation-content.ts\` so the same
+             corruption is corrected on future syncs.

-## Agent mode in the IDE
+## Third-party agents
 
-Enterprise and organization owners can separately control whether their users have access to agent mode in IDE chat, independently from the "Chat in IDE" policy. This gives you finer-grained control over agentic capabilities in your developers' IDEs.
+Third-party agents, or partner agents, such as Claude and Codex work alongside {% data variables.copilot.copilot_cloud_agent %} to complete development tasks asynchronously on {% data variables.product.github %}. While they share the same security protections and mitigations as {% data variables.copilot.copilot_cloud_agent %}, their policies are managed separately. Disabling or restricting {% data variables.copilot.copilot_cloud_agent %} does not automatically disable third-party agents, and vice versa. Each agent type must be configured independently.
+
+Enterprise administrators and AI managers can control the availability of third-party agents from the Agents page in the AI Controls view. These policies govern third-party agent usage on {% data variables.product.prodname_dotcom_the_website %}.
+
+For more information about available third-party agents, see [AUTOTITLE](/copilot/concepts/agents/about-third-party-agents).
+
+## Local agents
+
+Agents running in {% data variables.product.prodname_vscode %} are not managed through {% data variables.product.github %} at all. Instead, they are an IDE feature with their own configuration.
 
-To manage this policy, enable or disable **Copilot Agent Mode in IDE chat** in your AI Controls settings. For more information, see [AUTOTITLE](/copilot/how-tos/administer-copilot/manage-for-enterprise/manage-enterprise-policies).
+For more information, see [Types of agents](https://code.visualstudio.com/docs/copilot/agents/overview#_types-of-agents) and [Enable or disable the use of agents](https://code.visualstudio.com/docs/enterprise/ai-settings#_enable-or-disable-the-use-of-agents) in the {% data variables.product.prodname_vscode %} documentation.
 
-## Next steps
+## MCP servers
 
-To get started with {% data variables.copilot.custom_agents_short %}, see [AUTOTITLE](/copilot/how-tos/administer-copilot/manage-for-enterprise/manage-agents/prepare-for-custom-agents).
+Model Context Protocol (MCP) servers give agents access to external tools and data sources. Enterprise owners can control how MCP servers are discovered and used across the enterprise through a dedicated set of MCP policies in the AI Controls view.
 
-## Further reading
+To help you meet security and compliance requirements, you can choose to:
+* Allow or block MCP server usage entirely
+* Control which external tools are available to agents using an MCP registry (catalogs of approved MCP servers that your developers can discover and use)
+
+Private MCP registries apply to {% data variables.copilot.copilot_cli_short %} and IDEs, but not to cloud agents that run on {% data variables.product.github %}. For {% data variables.copilot.copilot_cloud_agent %}, MCP servers can be configured at the repository level or in custom agent profiles defined at the enterprise level.
