Kyle Carberry	cd56ab9e33	refactor: remove legacy live-read and injected-history chat context paths (#26585) ... This PR makes the agent-pushed pinned snapshot (`chat_context_resources`) the sole source of workspace context for chats, completing the "Release 5" cleanup. It removes legacy mechanisms now superseded by the snapshot that agents push over dRPC (`PushContextState`) and refresh via `chat-context/refresh`. Removed: - **Live-read at turn time.** MCP tool discovery, skill live-body reads, and the instruction/skill history fallback that dialed the workspace on every turn. - **Context injected as message history.** The `persist_workspace_context` generation action and its decision-loop guard. - **The legacy write path.** `POST`/`DELETE /api/v2/workspaceagents/me/experimental/chat-context`, the agentsdk `AddChatContext`/`ClearChatContext` methods, and the CLI one-shot writer. - **The `chats.last_injected_context` column** and all of its plumbing (migration `000529`, queries, `db2sdk`, `dbauthz`, audit table, and the frontend `ContextUsageIndicator` fallback). Subagent context inheritance no longer copies parent context messages; children now hydrate the parent's pinned `chat_context_resources` on create, which yields an identical pin for the same workspace and agent. What stays (still served by the live agent connection, not the snapshot): `read_skill_file` supporting-file reads, `read_skill` supporting-file listing, and MCP tool execution. > [!NOTE] > Migration `000529` drops `chats.last_injected_context` and recreates the `chats_expanded` view without it. The down migration restores both. <details> <summary>Decision log (D1-D5)</summary> - **D1 (subagent inheritance):** Re-point inheritance from the legacy message copy to a pinned hydrate. Children call `hydrateChatContextOnCreate` instead of copying parent context messages. - **D2 (`persist_workspace_context`):** Remove the generation action entirely along with the decision-loop guard it existed to satisfy, since context is never injected into history anymore. - **D3 (legacy HTTP + CLI):** Remove the experimental `chat-context` POST/DELETE endpoints, the agentsdk methods, and the CLI one-shot. The dRPC push + `chat-context/refresh` replace them. - **D4 (frontend fallback):** Remove the `last_injected_context` fallback in `ContextUsageIndicator`; pinned `resources` are the sole source. - **D5 (sequencing):** Ship as a single PR rather than a stacked pair. </details> --- Coder Agents generated on behalf of @kylecarbs.	2026-06-22 19:26:34 -06:00
Ethan	bd6cc1aaf2	feat(coderd): add stop_workspace chatd tool and recovery classification (#24997) ... ## Summary Adds a `stop_workspace` tool to chatd so the model can recover from the "workspace running but agent dead" failure mode (e.g. an OOM that leaves the workspace running but the agent unreachable) by stopping and then starting the workspace. <img width="924" height="742" alt="image" src="https://github.com/user-attachments/assets/279dedb6-6e29-4fe1-8754-3a1f01e538bf" /> ## What changed **New `stop_workspace` chatd tool** (`coderd/x/chatd/chattool/stopworkspace.go`). Mirrors `start_workspace`: shares `WorkspaceMu` to serialize with create/start, waits for any in-progress build before issuing a stop, and is idempotent only after a successful Stop transition. Failed stop builds re-attempt rather than reporting success. **New `chatStopWorkspace` coderd hook** (`coderd/exp_chats.go`). Mirrors `chatStartWorkspace` minus the `RequireActiveVersion` gate. Stop should not be blocked by template version policy. **Differentiated recovery sentinels** (`coderd/x/chatd/chatd.go`). `errChatAgentDisconnected` instructs the model to call `stop_workspace` then `start_workspace`. `errChatDialTimeout` instructs a single retry, then user escalation if it repeats. The previous single message conflated transient and persistent failures. **Two-signal recovery gate.** Recovery is only surfaced when a tool call times out *and* a fresh DB read of the latest workspace agent says `Disconnected`. The previous draft escalated on the DB read alone, which would fire on a 30-second heartbeat blip (e.g. agent respawn) and prompt a destructive stop/start unnecessarily. **Cache-hit disconnected handling** now clears the cache and retries a fresh dial before escalating, rather than returning the recovery sentinel immediately. Latest-agent classification uses `GetWorkspaceAgentsInLatestBuildByWorkspaceID` instead of the chat's bound `AgentID`, so stale bindings after a rebuild don't misclassify. **Shared chattool helpers** in `coderd/x/chatd/chattool/chattool.go`: `latestWorkspaceBuildAndJob`, `publishBuildBinding`, `provisionerJobTerminal`. Applied to both `start_workspace` and `stop_workspace`. ## Notes - Reverts an earlier draft that widened `ask_user_question` to root standard turns. Plan-mode-only behavior is restored. - The `stop_workspace` tool currently renders via the generic chat tool-call UI. A follow-up frontend PR will prettify the `stop_workspace` tool and style it like the `start_workspace` tool. - Never-connected (`Timeout` status) agents are intentionally excluded from recovery. They indicate template or startup failure, not the running-but-dead case this PR targets. Closes CODAGT-315	2026-05-11 16:23:07 +10:00
3 people	04cc983833	fix: add preset support to MCP tools (#24694) ... The chat tools (`read_template`, `create_workspace`) did not surface or respect template version presets. Presets were invisible to the LLM and preset parameter defaults were never applied at workspace creation. The `toolsdk` MCP surface had the same gap (ref #24695, now subsumed here). ## What this changes - **`read_template`** returns presets with `id`, `name`, `default`, `description`, `icon`, `parameters`, and `desired_prebuild_instances` (when set), so the LLM can pick the right preset and prefer prebuilt-backed ones. - **`create_workspace`** accepts a `preset_id`. The wsbuilder applies preset parameter defaults and may claim a prebuilt workspace. - **`start_workspace`** does *not* accept a preset. Presets are a creation-time choice; subsequent starts use the workspace's existing version and parameters. Users who need a specific preset or version on an existing chat can create the workspace out-of-band (CLI / UI / API) with the desired configuration and attach the chat to it. - **`toolsdk`** gains `GetTemplate` (with presets including `desired_prebuild_instances`), preset support on `CreateWorkspace`, and preset + `rich_parameters` support on `CreateWorkspaceBuild`. The `template_version_preset_id` description warns about preset/version affinity. > 🤖 Generated with [Coder Agents](https://coder.com/agents) and reviewed by a human.

Kyle CarberryandMichael Suchacz	391b22aef7	feat: add CLI commands for managing chat context from workspaces (#24105) ... Adds `coder exp chat context add` and `coder exp chat context clear` commands that run inside a workspace to manage chat context files via the agent token. `add` reads instruction and skill files from a directory (defaulting to cwd) and inserts them as context-file messages into an active chat. Multiple calls are additive — `instructionFromContextFiles` already accumulates all context-file parts across messages. `clear` soft-deletes all context-file messages, causing `contextFileAgentID()` to return `!found` on the next turn, which triggers `needsInstructionPersist=true` and re-fetches defaults from the agent. Both commands auto-detect the target chat via `CODER_CHAT_ID` (already set by `agentproc` on chat-spawned processes), or fall back to single-active-chat resolution for the agent. The `--chat` flag overrides both. Also adds sub-agent context inheritance: `createChildSubagentChat` now copies parent context-file messages to child chats at spawn time, so delegated sub-agents share the same instruction context without independently re-fetching from the workspace agent. <details><summary>Implementation details</summary> **New files:** - `cli/exp_chat.go` — CLI command tree under `coder exp chat context` **Modified files:** - `agent/agentcontextconfig/api.go` — `ConfigFromDir()` reads context from an arbitrary directory without env vars - `codersdk/agentsdk/agentsdk.go` — `AddChatContext`/`ClearChatContext` SDK methods - `coderd/workspaceagents.go` — POST/DELETE handlers on `/workspaceagents/me/chat-context` - `coderd/coderd.go` — Route registration - `coderd/database/queries/chats.sql` — `GetActiveChatsByAgentID`, `SoftDeleteContextFileMessages` - `coderd/database/dbauthz/dbauthz.go` — RBAC implementations for new queries - `coderd/x/chatd/subagent.go` — `copyParentContextFiles` for sub-agent inheritance - `cli/root.go` — Register `chatCommand()` in `AGPLExperimental()` **Auth pattern:** Uses `AgentAuth` (same as `coder external-auth`) — agent token via `CODER_AGENT_TOKEN` + `CODER_AGENT_URL` env vars. </details> > 🤖 Generated by Coder Agents --------- Co-authored-by: Michael Suchacz <203725896+ibetitsmike@users.noreply.github.com>	2026-04-09 16:33:00 +02:00
