+Define and manage AI prompts with `prompts.define()`. Create typesafe prompt templates with variables, resolve them at runtime, and manage versions and overrides from the dashboard without redeploying.

+Fix dev CLI leaking build directories on rebuild, causing disk space accumulation. Deprecated workers are now pruned (capped at 2 retained) when no active runs reference them. The watchdog process also cleans up `.trigger/tmp/` when the dev CLI is killed ungracefully (e.g. SIGKILL from pnpm).

+Add `get_span_details` MCP tool for inspecting individual spans within a run trace.
+
+- New `get_span_details` tool returns full span attributes, timing, events, and AI enrichment (model, tokens, cost, speed)
+- Span IDs now shown in `get_run_details` trace output for easy discovery
+- New API endpoint `GET /api/v1/runs/:runId/spans/:spanId`
+- New `retrieveSpan()` method on the API client

+
+MCP server improvements: new tools, bug fixes, and new flags.
+
+**New tools:**
+- `get_query_schema` — discover available TRQL tables and columns
+- `query` — execute TRQL queries against your data
+- `list_dashboards` — list built-in dashboards and their widgets
+- `run_dashboard_query` — execute a single dashboard widget query
+- `whoami` — show current profile, user, and API URL
+- `list_profiles` — list all configured CLI profiles
+- `switch_profile` — switch active profile for the MCP session
+- `start_dev_server` — start `trigger dev` in the background and stream output
+- `stop_dev_server` — stop the running dev server
+- `dev_server_status` — check dev server status and view recent logs
+
+**New API endpoints:**
+- `GET /api/v1/query/schema` — query table schema discovery
+- `GET /api/v1/query/dashboards` — list built-in dashboards
+
+**New features:**
+- `--readonly` flag hides write tools (`deploy`, `trigger_task`, `cancel_run`) so the AI cannot make changes
+- `read:query` JWT scope for query endpoint authorization
+- `get_run_details` trace output is now paginated with cursor support
+- MCP tool annotations (`readOnlyHint`, `destructiveHint`) for all tools
+
+**Bug fixes:**
+- Fixed `search_docs` tool failing due to renamed upstream Mintlify tool (`SearchTriggerDev` → `search_trigger_dev`)
+- Fixed `list_deploys` failing when deployments have null `runtime`/`runtimeVersion` fields (#3139)
+- Fixed `list_preview_branches` crashing due to incorrect response shape access
+- Fixed `metrics` table column documented as `value` instead of `metric_value` in query docs
+- Fixed dev CLI leaking build directories on rebuild — deprecated workers now clean up their build dirs when their last run completes
+
+**Context optimizations:**
+- `get_query_schema` now requires a table name and returns only one table's schema (was returning all tables)
+- `get_current_worker` no longer inlines payload schemas; use new `get_task_schema` tool instead
+- Query results formatted as text tables instead of JSON (~50% fewer tokens)
+- `cancel_run`, `list_deploys`, `list_preview_branches` formatted as text instead of raw JSON
+- Schema and dashboard API responses cached to avoid redundant fetches
