Struct FormatPipelineEnricher 

pub struct FormatPipelineEnricher;

Format pipeline enricher — adds pipeline-level parameters to list tools.

Adds these parameters (using safe naming to avoid collisions):

• format — output format (toon/json)
• budget — token budget for response size control
• chunk — chunk number for navigating large results

API-level limit/offset are defined by individual tools where the provider API supports pagination. The enricher does NOT add them.

Trait Implementations

impl ToolEnricher for FormatPipelineEnricher

fn supported_categories(&self) -> &[ToolCategory]

Which tool categories this provider/enricher supports. Tools from other categories won’t be shown when this enricher is active.

fn enrich_schema(&self, tool_name: &str, schema: &mut ToolSchema)

Modify the tool schema during tools/list.

fn transform_args(&self, _tool_name: &str, args: &mut Value)

Transform arguments before tool execution.

fn value_model(&self, _tool_name: &str) -> Option<ToolValueModel>

Optional: provider-shipped value model for tool_name. Returned models are merged into AdaptiveConfig.tools at startup so the Paper 3 enrichment planner can read them via effective_tool_value_model.

fn project_args( &self, _prev_tool: &str, _prev_result: &Value, _link: &FollowUpLink, ) -> Option<Value>

Build the JSON arguments for a speculatively pre-fetched follow-up call.

fn rate_limit_host(&self, _tool_name: &str, _args: &Value) -> Option<String>

Optional dynamic rate-limit host for tool_name, derived from runtime args. Provider returns the network host the call will hit (e.g. Some("api.github.com")) so the speculative dispatcher can cap concurrent in-flight prefetches per host.
