This page collects every limit you can run into, grouped by area. When a request goes over one, the error's `details` usually reports the limit and the measured value, so your code can react without parsing the message. ## Account and access | Limit | Value | Details | | ----------------------------- | ---------------------------- | ------------------------------------------------------------------ | | API key name | 100 characters | [API keys](/managed-agents/api-keys) | | API key lifetime | 365 days. Every key expires. | [API keys](/managed-agents/api-keys) | | Live organizations per tenant | 100 | [Organizations and roles](/managed-agents/organizations-and-roles) | | Organization name | 40 characters | [Organizations and roles](/managed-agents/organizations-and-roles) | | Tenant name | 100 characters | [Organizations and roles](/managed-agents/organizations-and-roles) | ## Requests | Limit | Value | When exceeded | | ----------------------- | ------------------------------------------------------------------------------------------------------ | ---------------------------------------------- | | Request rate per person | Not published. Shared across all your keys and console use. | `429 rate_limit_exceeded` with `Retry-After`. | | Open event streams | Not published. | `503 service_unavailable`. | | `Idempotency-Key` | 1 to 256 visible ASCII characters, one header value | `400 invalid_request`. | | Idempotency memory | About 24 hours for a completed request. An abandoned in-progress key can be reused after about 1 hour. | After that, the same key starts a new request. | | Session list page token | Valid for 1 hour, with the same filters and `limit` | `400 invalid_request` on `page_token`. | See [API conventions](/managed-agents/api#rate-limits) for retry guidance. ## Agents | Limit | Value | Details | | ------------------------------ | ----------------------------------------------------------------------- | ------------------------------------------------ | | Agent name | 256 characters | [Agent setup](/managed-agents/agents) | | Skills on one agent or session | 100, after groups are expanded and duplicates removed | [Skills](/managed-agents/skills) | | `max_concurrent_sessions` | 1 to 10,000, or unset for no cap. Extra root sessions wait as `queued`. | [Usage and cost](/managed-agents/usage-and-cost) | | Tags on one agent | 32 | [Agent setup](/managed-agents/agents) | | Tags per organization | 200 | [Agent setup](/managed-agents/agents) | | Tag label | 32 characters | [Agent setup](/managed-agents/agents) | | Tag description | 280 characters | [Agent setup](/managed-agents/agents) | | Tag ids in one list filter | 32 | [Agent setup](/managed-agents/agents) | ## Sessions and events | Limit | Value | Details | | ------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------- | | Custom metadata on a session | 32 pairs.

A page stops at about 8 MiB, so it can hold fewer. | [Events](/managed-agents/events) | | One stream record | The stream's `Content-Type` states the largest record it sends. A larger event arrives as `event_record_too_large`; fetch it with `getSessionEventContent`. | [Events](/managed-agents/events) | | Stream keep-alive | A ping every 15 seconds | [Events](/managed-agents/events) | | Live snapshot (gestalt) | 5,000 sessions, over a 30-day window (400 days when filtered by `agent_id`) | [Events](/managed-agents/events) | | Resource-sample page | 120 buckets by default, 720 at most | [Session operations](/managed-agents/session-operations) | | Sandbox provisioning | Fails with `sandbox_provision_timeout` if compute isn't ready within 5 minutes | [Sessions](/managed-agents/sessions) | ## Outcomes | Limit | Value | Details | | ------------------------- | --------------------------------------------------------------------- | ------------------------------------ | | Criteria in one rubric | 1 to 200 | [Outcomes](/managed-agents/outcomes) | | Open outcomes per session | 1. Define the next after the current one is graded. | [Outcomes](/managed-agents/outcomes) | | `max_iterations` | Omitted or `0` means no cap. Any positive number caps grading passes. | [Outcomes](/managed-agents/outcomes) | | Criterion weight | Always 1 | [Outcomes](/managed-agents/outcomes) | ## Deliverables | Limit | Value | Details | | -------------------------------------- | -------------------------------------------------------------------- | -------------------------------------- | | Files kept per turn | 200 | [Artifacts](/managed-agents/artifacts) | | Bytes kept per turn | 512 MiB | [Artifacts](/managed-agents/artifacts) | | One deliverable file | 64 MiB | [Artifacts](/managed-agents/artifacts) | | Files considered in the outputs folder | 10,000 per turn | [Artifacts](/managed-agents/artifacts) | | Deliverable file name | 255 characters, no control characters | [Artifacts](/managed-agents/artifacts) | | Image shown with `share_file` | PNG, JPEG, or WebP; 5 MiB, 8,192 pixels on a side, and 40 megapixels | [Artifacts](/managed-agents/artifacts) | | Images per session | 500 images and 100 MiB, across every tool that returns images | [Artifacts](/managed-agents/artifacts) | A file over the per-file size, or with a name that breaks the rules above, isn't kept, and the session records a warning. Files past a turn's file or byte cap wait for the next turn. Download kept files from the session's **Files** tab; see [Files](/managed-agents/files). ## Tools | Limit | Value | Details | | ------------------ | ---------------------------------------- | ------------------------------------------ | | MCP server request | 60-second timeout; responses up to 8 MiB | [MCP servers](/managed-agents/mcp-servers) | ## Integrations | Limit | Value | Details | | ------------------------------------------- | --------------------------------------------------------------------------- | --------------------------------------------------------------------------------------- | | Connections per app | 1 per organization | [Integrations](/managed-agents/integrations#connect-an-app) | | Tools on one app's allow-list | 1 to 200.
