}

Tool-execution signals extracted from a normalized Request.

A request-side processor stores these signals in State for crate::StageRouter and its classifier to consume.

Fields

severity: f32

Max severity across the recent window (last recent_window tool results): 0.0 clean · 0.3 soft (exit_nonzero) · 0.7 hard · 1.0 critical. Windowed so an error persists through the recovery turns instead of clearing the instant the next result is clean.

no_error_streak: u32

Consecutive clean tool results back from the most recent. 0 if the last failed.

edit_count: u32

Total edit-style tool calls in the request.

write_count: u32

Total write-style tool calls in the request.

read_count: u32

Read-type calls (Read tool + read-like Bash). Used by the build-pit gate.

todowrite_count: u32

TodoWrite / planning tool calls. Investigative (non-producing) activity — recent todowrites distinguish exploring from spinning in the scorer.

recent_edit_count: u32

Edit-type calls within the configured recent window (default: DEFAULT_RECENT_WINDOW).

recent_write_count: u32

Write-type calls within the configured recent window (default: DEFAULT_RECENT_WINDOW).

recent_read_count: u32

Read-type calls within the configured recent window (default: DEFAULT_RECENT_WINDOW).

recent_todowrite_count: u32

TodoWrite calls within the configured recent window (default: DEFAULT_RECENT_WINDOW).

pure_bash_streak: u32

Consecutive trailing tool calls in the Other category (no Write/Edit/Read/ Plan match). Surfaced in the classifier state summary; not scored directly.

tests_passed: bool

At least one of the last three tool results matched a test-pass pattern.

turn_depth: u32

Message-count proxy for turn depth. Wire-format dependent (Anthropic batches tool results into fewer messages than OpenAI-chat), so gates keyed on it are approximate across request origins.

compacted: bool

The request carries a context-compaction summary (the agent’s context was summarised after overflowing). Compaction resets the router’s accumulated signals, so a task that was on the strong tier de-escalates back to weak — the picker uses this to force + hold the strong tier. Self-latching: the summary stays in the context prefix on every subsequent turn.

Implementations

impl ToolSignals

pub fn from_request(request: &Request, window_size: Option<usize>) -> Self

Extracts tool and progress signals from request.

window_size limits recent counters to the newest tool results. None uses DEFAULT_RECENT_WINDOW.

Trait Implementations

impl Clone for ToolSignals

fn clone(&self) -> ToolSignals

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ToolSignals

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ToolSignals

fn default() -> ToolSignals

Returns the “default value” for a type.
