chore: regenerate OpenAPI schema for new LLM endpoints

Implements public GET endpoints for querying LLM models and providers - Part 3 of 6 in the incremental registry rollout.

**Endpoints:**
- GET /api/llm/models - List all models (filterable by enabled_only)
- GET /api/llm/providers - List providers with their models

**Design:**
- Uses in-memory registry from PR 2 (no DB queries)
- Fast reads from cache populated at startup
- Grouped by provider for easy UI rendering

**Response models:**
- LlmModel - model info with capabilities, costs, creator
- LlmProvider - provider with nested models
- LlmModelsResponse - list + total count
- LlmProvidersResponse - grouped by provider

**Authentication:**
- Requires user auth (requires_user dependency)
- Public within authenticated sessions

**Integration:**
- Registered in rest_api.py at /api prefix
- Tagged with v2 + llm for OpenAPI grouping

**What's NOT included (later PRs):**
- Admin write API (PR 4)
- Block integration (PR 5)
- Redis cache (PR 6)

+2. **Fix** any remaining errors manually, re-run until clean
+3. **Test**: `poetry run test` (runs DB setup + pytest). For specific files: `poetry run pytest -s -vvv <test_files>`
+4. **Snapshots** (if needed): `poetry run pytest path/to/test.py --snapshot-update` — review with `git diff`

+
+# Code Style
+
+## Imports
+
+- **Top-level only** — no local/inner imports. Move all imports to the top of the file.
+
+## Typing
+
+- **No duck typing** — avoid `hasattr`, `getattr`, `isinstance` for type dispatch. Use proper typed interfaces, unions, or protocols.
+- **Pydantic models** over dataclass, namedtuple, or raw dict for structured data.
+- **No linter suppressors** — avoid `# type: ignore`, `# noqa`, `# pyright: ignore` etc. 99% of the time the right fix is fixing the type/code, not silencing the tool.
+
+## Code Structure
+
+- **List comprehensions** over manual loop-and-append.
+- **Early return** — guard clauses first, avoid deep nesting.
+- **Flatten inline** — prefer short, concise expressions. Reduce `if/else` chains with direct returns or ternaries when readable.
+- **Modular functions** — break complex logic into small, focused functions rather than long blocks with nested conditionals.
+
+## Review Checklist
+
+Before finishing, always ask:
+- Can any function be split into smaller pieces?
+- Is there unnecessary nesting that an early return would eliminate?
+- Can any loop be a comprehension?
+- Is there a simpler way to express this logic?

+# New Block Creation
+
+Read `docs/platform/block-sdk-guide.md` first for the full guide.
+
+## Steps
+
+1. **Provider config** (if external service): create `_config.py` with `ProviderBuilder`
+2. **Block file** in `backend/blocks/` (from `autogpt_platform/backend/`):
+   - Generate a UUID once with `uuid.uuid4()`, then **hard-code that string** as `id` (IDs must be stable across imports)
+   - `Input(BlockSchema)` and `Output(BlockSchema)` classes
+   - `async def run` that `yield`s output fields
+3. **Files**: use `store_media_file()` with `"for_block_output"` for outputs
+4. **Test**: `poetry run pytest 'backend/blocks/test/test_block.py::test_available_blocks[MyBlock]' -xvs`
+5. **Format**: `poetry run format`
+
+## Rules
+
+- Analyze interfaces: do inputs/outputs connect well with other blocks in a graph?
+- Use top-level imports, avoid duck typing
+- Always use `for_block_output` for block outputs

+
+## Steps
+
+1. **Check for existing PR**: `gh pr view --json url -q .url 2>/dev/null` — if a PR already exists, output its URL and stop
+2. **Understand changes**: `git status`, `git diff dev...HEAD`, `git log dev..HEAD --oneline`
+3. **Read PR template**: `.github/PULL_REQUEST_TEMPLATE.md`
+4. **Draft PR title**: Use conventional commits format (see CLAUDE.md for types and scopes)
+5. **Fill out PR template** as the body — be thorough in the Changes section
+6. **Format first** (if relevant changes exist):
+   - Backend: `cd autogpt_platform/backend && poetry run format`
+   - Frontend: `cd autogpt_platform/frontend && pnpm format`
+   - Fix any lint errors, then commit formatting changes before pushing

+# PR Review Comment Workflow
+
+## Steps
+
+1. **Find PR**: `gh pr list --head $(git branch --show-current) --repo Significant-Gravitas/AutoGPT`
+2. **Fetch comments** (all three sources):
+   - `gh api repos/Significant-Gravitas/AutoGPT/pulls/{N}/reviews` (top-level reviews)
+   - `gh api repos/Significant-Gravitas/AutoGPT/pulls/{N}/comments` (inline review comments)
+   - `gh api repos/Significant-Gravitas/AutoGPT/issues/{N}/comments` (PR conversation comments)
+3. **Skip** comments already reacted to by PR author
+4. **For each unreacted comment**:
+   - Read referenced code, make the fix (or reply if you disagree/need info)
+   - **Inline review comments** (`pulls/{N}/comments`):
+     - React: `gh api repos/.../pulls/comments/{ID}/reactions -f content="+1"` (or `-1`)
+     - Reply: `gh api repos/.../pulls/{N}/comments/{ID}/replies -f body="..."`
+   - **PR conversation comments** (`issues/{N}/comments`):
+     - React: `gh api repos/.../issues/comments/{ID}/reactions -f content="+1"` (or `-1`)
+     - No threaded replies — post a new issue comment if needed
+   - **Top-level reviews**: no reaction API — address in code, reply via issue comment if needed
+5. **Include autogpt-reviewer bot fixes** too
+6. **Format**: `cd autogpt_platform/backend && poetry run format`, `cd autogpt_platform/frontend && pnpm format`
+7. **Commit & push**
+8. **Re-fetch comments** immediately — address any new unreacted ones before waiting on CI
+9. **Stay productive while CI runs** — don't idle. In priority order:
+   - Run any pending local tests (`poetry run pytest`, e2e, etc.) and fix failures
+   - Address any remaining comments
+   - Only poll `gh pr checks {N}` as the last resort when there's truly nothing left to do
+10. **If CI fails** — fix, go back to step 6
+11. **Re-fetch comments again** after CI is green — address anything that appeared while CI was running
+12. **Done** only when: all comments reacted AND CI is green.
+
+## CRITICAL: Do Not Stop
+
+**Loop is: address → format → commit → push → re-check comments → run local tests → wait CI → re-check comments → repeat.**
+
+Never idle. If CI is running and you have nothing to address, run local tests. Waiting on CI is the last resort.
+
+## Rules
+
+- One todo per comment
+- For inline review comments: reply on existing threads. For PR conversation comments: post a new issue comment (API doesn't support threaded replies)
+- React to every comment: +1 addressed, -1 disagreed (with explanation)

+# Worktree Setup
+
+## Preferred: Use Branchlet
+
+The repo has a `.branchlet.json` config — it handles env file copying, dependency installation, and Prisma generation automatically.
+
+```bash
+npm install -g branchlet                                      # install once
+branchlet create -n <name> -s <source-branch> -b <new-branch>
+branchlet list --json   # list all worktrees
+```
+
+## Manual Fallback
+
+If branchlet isn't available:
+
+1. `git worktree add ../<RepoName><N> <branch-name>`
+2. Copy `.env` files: `backend/.env`, `frontend/.env`, `autogpt_platform/.env`, `db/docker/.env`
+3. Install deps:
+   - `cd autogpt_platform/backend && poetry install && poetry run prisma generate`
+   - `cd autogpt_platform/frontend && pnpm install`
+
+## Running the App
+
+Free ports first — backend uses: 8001, 8002, 8003, 8005, 8006, 8007, 8008.
+
+```bash
+for port in 8001 8002 8003 8005 8006 8007 8008; do
+  lsof -ti :$port | xargs kill -9 2>/dev/null || true
+done
+cd <worktree>/autogpt_platform/backend && poetry run app
+```
+
+## CoPilot Testing Gotcha
+
+SDK mode spawns a Claude subprocess — **won't work inside Claude Code**. Set `CHAT_USE_CLAUDE_AGENT_SDK=false` in `backend/.env` to use baseline mode.

-"""Redis Streams consumer for operation completion messages.
-
-This module provides a consumer (ChatCompletionConsumer) that listens for
-completion notifications (OperationCompleteMessage) from external services
-(like Agent Generator) and triggers the appropriate stream registry and
-chat service updates via process_operation_success/process_operation_failure.
-
-Why Redis Streams instead of RabbitMQ?
---------------------------------------
-While the project typically uses RabbitMQ for async task queues (e.g., execution
-queue), Redis Streams was chosen for chat completion notifications because:
-
-1. **Unified Infrastructure**: The SSE reconnection feature already uses Redis
-   Streams (via stream_registry) for message persistence and replay. Using Redis
-   Streams for completion notifications keeps all chat streaming infrastructure
-   in one system, simplifying operations and reducing cross-system coordination.
-
-2. **Message Replay**: Redis Streams support XREAD with arbitrary message IDs,
-   allowing consumers to replay missed messages after reconnection. This aligns
-   with the SSE reconnection pattern where clients can resume from last_message_id.
-
-3. **Consumer Groups with XAUTOCLAIM**: Redis consumer groups provide automatic
-   load balancing across pods with explicit message claiming (XAUTOCLAIM) for
-   recovering from dead consumers - ideal for the completion callback pattern.
-
-4. **Lower Latency**: For real-time SSE updates, Redis (already in-memory for
-   stream_registry) provides lower latency than an additional RabbitMQ hop.
-
-5. **Atomicity with Task State**: Completion processing often needs to update
-   task metadata stored in Redis. Keeping both in Redis enables simpler
-   transactional semantics without distributed coordination.
-
-The consumer uses Redis Streams with consumer groups for reliable message
-processing across multiple platform pods, with XAUTOCLAIM for reclaiming
-stale pending messages from dead consumers.

+
+- **Any file** — shows as a clickable download link:

+Instead of copying large file contents into a tool argument, pass a file
+reference and the platform will load the content for you.
+
+Syntax: `@@agptfile:<uri>[<start>-<end>]`
+
+- `<uri>` **must** start with `workspace://` or `/` (absolute path):
+  - `workspace://<file_id>` — workspace file by ID
+  - `workspace:///<path>` — workspace file by virtual path
+  - `/absolute/local/path` — ephemeral or sdk_cwd file
+  - E2B sandbox absolute path (e.g. `/home/user/script.py`)
+- `[<start>-<end>]` is an optional 1-indexed inclusive line range.
+- URIs that do not start with `workspace://` or `/` are **not** expanded.

+@@agptfile:workspace://abc123
+@@agptfile:workspace://abc123[10-50]

+## Agent Generation Guide
+
+You can create, edit, and customize agents directly. You ARE the brain —
+generate the agent JSON yourself using block schemas, then validate and save.
+
+### Workflow for Creating/Editing Agents
+
+1. **Discover blocks**: Call `find_block(query, include_schemas=true)` to
+   search for relevant blocks. This returns block IDs, names, descriptions,
+   and full input/output schemas.
+2. **Find library agents**: Call `find_library_agent` to discover reusable
+   agents that can be composed as sub-agents via `AgentExecutorBlock`.
+3. **Generate JSON**: Build the agent JSON using block schemas:
+   - Use block IDs from step 1 as `block_id` in nodes
+   - Wire outputs to inputs using links
+   - Set design-time config in `input_default`
+   - Use `AgentInputBlock` for values the user provides at runtime
+4. **Write to workspace**: Save the JSON to a workspace file so the user
+   can review it: `write_workspace_file(filename="agent.json", content=...)`
+5. **Validate**: Call `validate_agent_graph` with the agent JSON to check
+   for errors
+6. **Fix if needed**: Call `fix_agent_graph` to auto-fix common issues,
+   or fix manually based on the error descriptions. Iterate until valid.
+7. **Save**: Call `create_agent` (new) or `edit_agent` (existing) with
+   the final `agent_json`
+
+### Agent JSON Structure
+
+```json
+{
+  "id": "<UUID v4>",        // auto-generated if omitted
+  "version": 1,
+  "is_active": true,
+  "name": "Agent Name",
+  "description": "What the agent does",
+  "nodes": [
+    {
+      "id": "<UUID v4>",
+      "block_id": "<block UUID from find_block>",
+      "input_default": {
+        "field_name": "design-time value"
+      },
+      "metadata": {
+        "position": {"x": 0, "y": 0},
+        "customized_name": "Optional display name"
+      }
+    }
+  ],
+  "links": [
+    {
+      "id": "<UUID v4>",
+      "source_id": "<source node UUID>",
+      "source_name": "output_field_name",
+      "sink_id": "<sink node UUID>",
+      "sink_name": "input_field_name",
+      "is_static": false
+    }
+  ]
+}
+```
+
+### REQUIRED: AgentInputBlock and AgentOutputBlock
+
+Every agent MUST include at least one AgentInputBlock and one AgentOutputBlock.
+These define the agent's interface — what it accepts and what it produces.
+
+**AgentInputBlock** (ID: `c0a8e994-ebf1-4a9c-a4d8-89d09c86741b`):
+- Defines a user-facing input field on the agent
+- Required `input_default` fields: `name` (str), `value` (default: null)
+- Optional: `title`, `description`, `placeholder_values` (for dropdowns)
+- Output: `result` — the user-provided value at runtime
+- Create one AgentInputBlock per distinct input the agent needs
+
+**AgentOutputBlock** (ID: `363ae599-353e-4804-937e-b2ee3cef3da4`):
+- Defines a user-facing output displayed after the agent runs
+- Required `input_default` fields: `name` (str)
+- The `value` input should be linked from another block's output
+- Optional: `title`, `description`, `format` (Jinja2 template)
+- Create one AgentOutputBlock per distinct result to show the user
+
+Without these blocks, the agent has no interface and the user cannot provide
+inputs or see outputs. NEVER skip them.
+
+### Key Rules
+
+- **Name & description**: Include `name` and `description` in the agent JSON
+  when creating a new agent, or when editing and the agent's purpose changed.
+  Without these the agent gets a generic default name.
+- **Design-time vs runtime**: `input_default` = values known at build time.
+  For user-provided values, create an `AgentInputBlock` node and link its
+  output to the consuming block's input.
+- **Credentials**: Do NOT require credentials upfront. Users configure
+  credentials later in the platform UI after the agent is saved.
+- **Node spacing**: Position nodes with at least 800 X-units between them.
+- **Nested properties**: Use `parentField_#_childField` notation in link
+  sink_name/source_name to access nested object fields.
+- **is_static links**: Set `is_static: true` when the link carries a
+  design-time constant (matches a field in inputSchema with a default).
+- **ConditionBlock**: Needs a `StoreValueBlock` wired to its `value2` input.
+- **Prompt templates**: Use `{{variable}}` (double curly braces) for
+  literal braces in prompt strings — single `{` and `}` are for
+  template variables.
+- **AgentExecutorBlock**: When composing sub-agents, set `graph_id` and
+  `graph_version` in input_default, and wire inputs/outputs to match
+  the sub-agent's schema.
+
+### Using Sub-Agents (AgentExecutorBlock)
+
+To compose agents using other agents as sub-agents:
+1. Call `find_library_agent` to find the sub-agent — the response includes
+   `graph_id`, `graph_version`, `input_schema`, and `output_schema`
+2. Create an `AgentExecutorBlock` node (ID: `e189baac-8c20-45a1-94a7-55177ea42565`)
+3. Set `input_default`:
+   - `graph_id`: from the library agent's `graph_id`
+   - `graph_version`: from the library agent's `graph_version`
+   - `input_schema`: from the library agent's `input_schema` (JSON Schema)
+   - `output_schema`: from the library agent's `output_schema` (JSON Schema)
+   - `user_id`: leave as `""` (filled at runtime)
+   - `inputs`: `{}` (populated by links at runtime)
+4. Wire inputs: link to sink names matching the sub-agent's `input_schema`
+   property names (e.g., if input_schema has a `"url"` property, use
+   `"url"` as the sink_name)
+5. Wire outputs: link from source names matching the sub-agent's
+   `output_schema` property names
+6. Pass `library_agent_ids` to `create_agent`/`customize_agent` with
+   the library agent IDs used, so the fixer can validate schemas
+
+### Using MCP Tools (MCPToolBlock)
+
+To use an MCP (Model Context Protocol) tool as a node in the agent:
+1. The user must specify which MCP server URL and tool name they want
+2. Create an `MCPToolBlock` node (ID: `a0a4b1c2-d3e4-4f56-a7b8-c9d0e1f2a3b4`)
+3. Set `input_default`:
+   - `server_url`: the MCP server URL (e.g. `"https://mcp.example.com/sse"`)
+   - `selected_tool`: the tool name on that server
+   - `tool_input_schema`: JSON Schema for the tool's inputs
+   - `tool_arguments`: `{}` (populated by links or hardcoded values)
+4. The block requires MCP credentials — the user configures these in the
+   platform UI after the agent is saved
+5. Wire inputs using the tool argument field name directly as the sink_name
+   (e.g., `query`, NOT `tool_arguments_#_query`). The execution engine
+   automatically collects top-level fields matching tool_input_schema into
+   tool_arguments.
+6. Output: `result` (the tool's return value) and `error` (error message)
+
+### Example: Simple AI Text Processor
+
+A minimal agent with input, processing, and output:
+- Node 1: `AgentInputBlock` (ID: `c0a8e994-ebf1-4a9c-a4d8-89d09c86741b`,
+  input_default: {"name": "user_text", "title": "Text to process"},
+  output: "result")
+- Node 2: `AITextGeneratorBlock` (input: "prompt" linked from Node 1's "result")
+- Node 3: `AgentOutputBlock` (ID: `363ae599-353e-4804-937e-b2ee3cef3da4`,
+  input_default: {"name": "summary", "title": "Summary"},
+  input: "value" linked from Node 2's output)

+## MCP Tool Guide
+
+### Workflow
+
+`run_mcp_tool` follows a two-step pattern:
+
+1. **Discover** — call with only `server_url` to list available tools on the server.
+2. **Execute** — call again with `server_url`, `tool_name`, and `tool_arguments` to run a tool.
+
+### Known hosted MCP servers
+
+Use these URLs directly without asking the user:
+
+| Service | URL |
+|---|---|
+| Notion | `https://mcp.notion.com/mcp` |
+| Linear | `https://mcp.linear.app/mcp` |
+| Stripe | `https://mcp.stripe.com` |
+| Intercom | `https://mcp.intercom.com/mcp` |
+| Cloudflare | `https://mcp.cloudflare.com/mcp` |
+| Atlassian / Jira | `https://mcp.atlassian.com/mcp` |
+
+For other services, search the MCP registry at https://registry.modelcontextprotocol.io/.
+
+### Authentication
