TASK-DESCRIPTION

• Create: documents/09-tool-integration.md
• Modify: documents/08-model-catalog.md

Write the tool-integration document.

Create documents/09-tool-integration.md covering:

• aider against the local routers: the invocation for editing (coder model, --edit-format whole) and architect mode (120B planner, coder editor), plus the historical usage note that past sessions used OpenRouter cloud models.
• llama.vscode: remote-server mode against the local routers, with per-purpose model recommendations (completion, chat, agent, embeddings) drawn from documents/08-model-catalog.md.
• VS Code Chat: the three options (GitHub Copilot BYOK with an OpenAI-compatible base URL, third-party gateway extensions, or skipping Chat in favor of llama.vscode/Cline/Roo), with the recommendation that overlapping agent UIs not run on the same project simultaneously.

Mark the document verified 2026-08-26 and note which facts are version-dependent (extension versions, flags) versus stable.

Do not modify any file outside documents/09-tool-integration.md.

TASK-OUTPUT

Provide a summary of the created document and its section list. No commentary beyond the summary.

TASK-CONTEXT

Feature requirements: prompts/features/04-aider-and-vscode.md. Model ids and contexts come from documents/08-model-catalog.md; do not restate the catalog independently. Historical aider usage was observed in the workspace .aider.* files (model-router-setup sessions used openrouter/openrouter/auto and openrouter-gpt-4o).
