# Runtime

Category Runtime: How an agent product executes work, delegates tasks, persists state, and requests approval.

- HTML: https://canmyagentuse.com/categories/runtime
- Markdown: https://canmyagentuse.com/categories/runtime.md

How an agent product executes work, delegates tasks, persists state, and requests approval.

The index groups these capabilities by job rather than vendor.

## Capabilities

- [Agent Skills](/features/agent-skills.md) — Agent Skills support is derived from atomic discovery, progressive loading, component, invocation, and scope claims.
- [Agent Skills core and discovery](/features/skills.md) — This atomic row covers recognizing, discovering, and loading standard SKILL.md packages. Scripts, assets, invocation, and scopes have separate sibling rows.
- [Agent Skills manual invocation](/features/skill-manual-invocation.md) — Agent Skills manual invocation is atomic and does not follow automatically from broader agent-skills support.
- [Agent Skills progressive loading](/features/skill-progressive-loading.md) — Agent Skills progressive loading is atomic and does not follow automatically from broader agent-skills support.
- [Agent Skills references and assets](/features/skill-references-assets.md) — Agent Skills references and assets is atomic and does not follow automatically from broader agent-skills support.
- [Agent Skills scripts](/features/skill-scripts.md) — Agent Skills scripts is atomic and does not follow automatically from broader agent-skills support.
- [Background agents](/features/background-agents.md) — Background agents continue running after the operator leaves the active session. Hosting, subscription, duration, and notification behavior are qualifiers.
- [Computer use](/features/computer-use.md) — Computer use is screenshot-informed interaction with a graphical interface through input actions. Browser-only and general desktop control are recorded separately.
- [Concurrent subagents](/features/subagent-concurrency.md) — Concurrent subagents means multiple child-agent tasks can overlap in time; sequential delegation, tool-call parallelism, and background shell processes are separate behaviors.
- [Human approval](/features/human-approval.md) — Human approval pauses an action until a person confirms or denies it. Action scope, remembered decisions, and policy behavior are qualifiers.
- [Long-term memory](/features/long-term-memory.md) — Long-term memory persists documented preferences or working context across sessions. Scope, user controls, shared storage, deletion, and security boundaries are qualifiers.
- [Nested subagents](/features/nested-subagents.md) — Nested subagents is atomic and does not follow automatically from broader subagents support.
- [Per-subagent model selection](/features/subagent-model-selection.md) — Per-subagent model selection means a child can use a documented model choice or constraint distinct from its parent; a global conversation model picker is insufficient.
- [Project-scoped Agent Skills](/features/skill-project-scope.md) — Project-scoped Agent Skills is atomic and does not follow automatically from broader agent-skills support.
- [Sandbox network access](/features/sandbox-network.md) — Sandbox network access means a product documents allowing, denying, or restricting outbound access from its execution sandbox.
- [Scheduled runs](/features/scheduled-runs.md) — Scheduled runs start saved tasks according to a schedule without a new human prompt. Hosting, limits, retention, and unattended-run behavior are qualifiers.
- [Subagent context](/features/subagent-context-isolation.md) — Subagent context describes what a child receives from its parent. Fresh context, copied history, selected files, shared memory, and task-only context are recorded as distinct qualifiers.
- [Subagent delegation](/features/subagent-delegation.md) — Basic delegation establishes one child-agent boundary but not recursion, MCP access, or write access.
- [Subagent management](/features/subagent-lifecycle-controls.md) — Subagent management covers visibility into active children and documented cancel, pause, resume, retry, or limit behavior. Each operation is recorded separately as a qualifier.
- [Subagent MCP access](/features/subagent-mcp-access.md) — Subagent MCP access is atomic and does not follow automatically from broader subagents support.
- [Subagent permissions](/features/subagent-approval-boundaries.md) — Subagent permissions describe which tools and grants a child receives and how child actions obtain approval. Inheritance, restrictions, and escalation behavior are qualifiers.
- [Subagent results](/features/subagent-result-handoff.md) — Subagent results describe what a child returns to its parent. Text summaries, files, citations, diffs, status, errors, and structured result objects are recorded as separate qualifiers.
- [Subagent write access](/features/subagent-write-access.md) — Subagent write access is atomic and does not follow automatically from broader subagents support.
- [Subagents](/features/subagents.md) — Subagents are a family of separate claims covering delegation, nesting, concurrency, context isolation, model choice, tool and write permissions, approvals, lifecycle control, and result handoff.
- [User-scoped Agent Skills](/features/skill-user-scope.md) — User-scoped Agent Skills is atomic and does not follow automatically from broader agent-skills support.
