Struct ToolCallRepairCapability 

pub struct ToolCallRepairCapability;

Opt-in capability that repairs malformed tool calls. Disabled by default: it is registered in the global registry but contributes nothing unless an agent explicitly enables it, and the reason atom only runs repair when the capability is present in the resolved capability set.

Trait Implementations

impl Capability for ToolCallRepairCapability

fn id(&self) -> &str

Returns the unique capability identifier as a string

fn name(&self) -> &str

Returns the display name

fn description(&self) -> &str

Returns a description of what this capability provides

fn is_guardrail(&self) -> bool

Whether this capability is a guardrail — a constraint on agent behavior (content checks, tool restrictions) rather than a grant of new abilities. Structural marker for UI sections and catalog filtering; carries no runtime semantics. See specs/guardrails.md.

fn config_schema(&self) -> Option<Value>

Returns the JSON Schema for this capability’s per-agent config.

fn validate_config(&self, config: &Value) -> Result<(), String>

Validates per-capability config before it is persisted.

fn localizations(&self) -> Vec<CapabilityLocalization>

Returns localization overlays for this capability’s display strings.

fn aliases(&self) -> Vec<&'static str>

Returns legacy identifiers that resolve to this capability.

fn localized_name(&self, locale: Option<&str>) -> String

Display name resolved for locale; None or unknown locales fall back to name().

fn localized_description(&self, locale: Option<&str>) -> String

Description resolved for locale; falls back to description().

fn describe_schema(&self, locale: Option<&str>) -> Option<String>

One-line human-readable summary of what this capability’s config controls, resolved for locale. None when the capability exposes no per-agent config.

fn status(&self) -> CapabilityStatus

Returns the current status of this capability

fn icon(&self) -> Option<&str>

Returns the icon name for UI rendering (optional)

fn category(&self) -> Option<&str>

Returns the category for grouping in UI (optional)

fn resolve_for_model(&self, _model: Option<&str>) -> Option<&dyn Capability>

Model-adaptive dispatch: delegate this capability’s contributions to a different underlying capability based on the agent’s model.

fn system_prompt_addition(&self) -> Option<&str>

Returns static text to include in the agent’s system prompt (optional).

fn system_prompt_contribution<'life0, 'life1, 'async_trait>( &'life0 self, _ctx: &'life1 SystemPromptContext, ) -> Pin<Box<dyn Future<Output = Option<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns the system prompt contribution for this capability, with access to session context (filesystem, etc.).

fn system_prompt_preview(&self) -> Option<String>

Returns a preview of the system prompt addition for UI display.

fn tools(&self) -> Vec<Box<dyn Tool>>

Returns tool implementations provided by this capability

fn tools_with_config(&self, _config: &Value) -> Vec<Box<dyn Tool>>

Returns tool implementations configured by per-capability config.

fn system_prompt_contribution_with_config<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 SystemPromptContext, _config: &'life2 Value, ) -> Pin<Box<dyn Future<Output = Option<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Returns system prompt contribution adapted to per-capability config.

fn tool_definitions(&self) -> Vec<ToolDefinition>

Returns tool definitions for the agent config By default, converts tools() to definitions

fn mounts(&self) -> Vec<MountPoint>

Returns mount points to populate in the session filesystem

fn dependencies(&self) -> Vec<&'static str>

Returns capability IDs that this capability depends on.

fn features(&self) -> Vec<&'static str>

Returns UI feature strings that this capability contributes to.

fn config_ui_schema(&self) -> Option<Value>

Returns UI hints for rendering config_schema.

fn mcp_servers(&self) -> ScopedMcpServers

Returns remote MCP servers contributed by this capability.

fn mcp_servers_with_config(&self, _config: &Value) -> ScopedMcpServers

Returns config-aware remote MCP server contributions.

fn message_filter_provider(&self) -> Option<Arc<dyn MessageFilterProvider>>

Returns a message filter provider if this capability modifies message retrieval.

fn model_view_provider(&self) -> Option<Arc<dyn ModelViewProvider>>

Returns a provider that can build a prompt-facing model view from lossless stored messages before provider serialization.

fn llm_error_hook(&self) -> Option<Arc<dyn LlmErrorHook>>

Returns an in-process hook invoked when a turn fails with a terminal LLM error (one that will not be retried), before the user-facing error message is emitted. The hook may perform a side effect (e.g. schedule a continuation) and/or return extra fields to augment the user-facing error copy. This is the platform seam for capability-owned error recovery — the same in-process hook family as Self::tool_call_hooks and Self::message_filter_provider; the reason atom invokes it generically and knows nothing about any specific capability’s behavior. See crate::llm_error_hook.

fn facts(&self, _config: &Value, _ctx: &FactsContext) -> Vec<Fact>

Returns key/value Facts this capability contributes to the model.

fn pre_tool_use_hooks(&self) -> Vec<Arc<dyn PreToolUseHook>>
