## Model Experience
| Context surface | What the model sees | Token effect |
|---|---|---|
| Session prefix | If model-invocable skills exist and this exact `skill` tool is visible, the agent receives the exact [catalog template](#skill-catalog-template), with one data-dependent entry per sorted skill. The catalog is a frozen user-role session prefix. | Repeated input cost scales with skill count and `catalogDescriptionMaxLength`; no catalog tokens are sent when the list is empty or the tool is hidden or shadowed. |
| Tool schema | The model sees `skill(name)` with exact description `Load the full instructions for an available skill. Call this with the exact skill name from the session skill catalog before acting on a task that names or clearly matches that skill.` and parameter description `The exact skill name from the available skills list.` | Fixed schema cost per request where the tool is visible. |
| Tool result | A successful call uses the exact [result template](#skill-result-template) with the exact [provider-managed](#provider-managed-resource-guidance), [directory](#directory-resource-guidance), [URL](#url-resource-guidance), or [opaque](#opaque-resource-guidance) resource guidance. | Loaded instructions are data-dependent tool-result tokens, resent on later steps until compaction; no duplicate `agent.inject()` copy is made. |
| Tool errors | Invalid or stale selections return exactly `Error: invalid skill name "<name>"`, `Error: skill "<name>" is unknown or no longer available`, or `Error: skill "<name>" is not available for model invocation`. Provider-thrown lookup text is data-dependent and receives the same `Error: <message>` wrapper. | Only a failing call adds these retained tokens. |
### Session prefix
**What the model sees**: If model-invocable skills exist and this exact `skill` tool is visible, the agent receives the exact [catalog template](#skill-catalog-template), with one data-dependent entry per sorted skill. The catalog is a frozen user-role session prefix.
**Token effect**: Repeated input cost scales with skill count and `catalogDescriptionMaxLength`; no catalog tokens are sent when the list is empty or the tool is hidden or shadowed.
### Tool schema
**What the model sees**: The model sees `skill(name)` with exact description `Load the full instructions for an available skill. Call this with the exact skill name from the session skill catalog before acting on a task that names or clearly matches that skill.` and parameter description `The exact skill name from the available skills list.`
**Token effect**: Fixed schema cost per request where the tool is visible.
### Tool result
**What the model sees**: A successful call uses the exact [result template](#skill-result-template) with the exact [provider-managed](#provider-managed-resource-guidance), [directory](#directory-resource-guidance), [URL](#url-resource-guidance), or [opaque](#opaque-resource-guidance) resource guidance.
**Token effect**: Loaded instructions are data-dependent tool-result tokens, resent on later steps until compaction; no duplicate `agent.inject()` copy is made.
### Tool errors
**What the model sees**: Invalid or stale selections return exactly `Error: invalid skill name "<name>"`, `Error: skill "<name>" is unknown or no longer available`, or `Error: skill "<name>" is not available for model invocation`. Provider-thrown lookup text is data-dependent and receives the same `Error: <message>` wrapper.
**Token effect**: Only a failing call adds these retained tokens.
