Short answers to the questions that show up most in community and support, with links to deeper docs.

Use this page when you need a fast pointer. Each answer links to the full concept or reference page.

## Models and cost [#models-and-cost]

**Which model should I pick?**\
Start with Latest Opus or Latest Sonnet for important work, a faster tier for Live heartbeats and bulk helpers. Details: [Supported models](/docs/concepts/agents/models).

**Why is a model missing from my picker?**\
It is not enabled for your account, or it is still rolling out. The picker is the source of truth.

## Tools, integrations, MCP, skills [#tools-integrations-mcp-skills]

**Skill vs integration vs MCP?**\
Method vs connected app vs external tool server. Decision tree: [Tools & Integrations](/docs/concepts/tools-and-integrations).

**Can MCP update skills?**\
No. Hosted MCP runs threads. Edit skills in the product. [Edit and import skills](/docs/concepts/skills/skills-edit-and-import).

**How do I connect an app that is not listed?**\
Custom MCP if the app speaks MCP; otherwise a skill with scripts and credentials. [Custom MCP](/docs/integrations/custom-mcp).

## Automation [#automation]

**Live Mode vs schedule?**\
Watch-and-alert vs timed job. [Live Mode](/docs/concepts/agents/invocations/live-mode), [Invocations](/docs/concepts/agents/invocations).

**Why did my schedule not post to Slack?**\
Check integration allow list, channel permissions, and unattended write settings. [Invocations](/docs/concepts/agents/invocations).

**Minimum Live Mode interval?**\
30 minutes. Default new cadence is about once per day until you change it.

## Agents working together [#agents-working-together]

**Can agents call agents?**\
Yes, with a depth cap of one named-agent hop. [Agent delegation](/docs/concepts/agents/agent-delegation).

**Child agent cannot see the parent chat**\
Expected. Put context in the brief.

## Knowledge and sharing [#knowledge-and-sharing]

**Personal vs Curated vs Team learning?**\
[Knowledge access](/docs/concepts/agents/knowledge-access). Use Curated for most Slack-shared agents.

**Import overwrote my skill**\
Normal import should not clobber in place; you may have a duplicate. [Edit and import skills](/docs/concepts/skills/skills-edit-and-import).

## Runtime [#runtime]

**Run died / tools vanished / long thread got weird**\
[Troubleshoot a stuck run](/docs/reference/runtime-limits).

## Billing [#billing]

**Credits, invoices, unexpected charges, promo balance**\
Use in-product billing settings and Support. Public docs do not publish plan price sheets here. Include your account email and approximate charge time when you contact Support.

## Still stuck [#still-stuck]

1. Open the thread and read the tool trail
2. Reproduce once in an interactive thread
3. Contact Support with thread link, timestamp, and screenshot
