}Expand description
Turn-level evaluation metadata, computed on-the-fly during flush with zero LLM calls.
Combines:
- Agent tuning (tune): persisted governor SymptomChannels (already computed, previously discarded after friction decisions).
- Developer coaching (coach): heuristic scores about request quality, session health, verification discipline, and scope management.
Designed to power unlost reflect later — the LLM at reflect-time reconstructs
the story from this structured telemetry only.
Fields§
§version: StringSchema version — always “v1” for this generation.
repetition: f32EMA-smoothed governor channel: symbol/topic repetition without progress.
novelty_collapse: f32EMA-smoothed governor channel: novelty collapse (agent running out of new approaches).
semantic_stall: f32EMA-smoothed governor channel: semantic stall (conversation going in circles).
effort_spike: f32EMA-smoothed governor channel: effort spike (agent doing far more than asked).
alignment_debt: f32EMA-smoothed governor channel: alignment debt (repeated user corrections).
path_hallucination: f32EMA-smoothed governor channel: path hallucination (referencing non-existent files).
grounding_stall: f32EMA-smoothed governor channel: grounding stall (agent ignoring user-mentioned paths).
instruction_staticness: f32EMA-smoothed governor channel: instruction staticness (user repeating long instructions).
logic_churn: f32EMA-smoothed governor channel: logic churn (rapid plan changes without progress).
fluency: f32EMA-smoothed governor channel: fluency (high verbosity vs user input — blind acceptance).
trajectory_intensity: f32Composite trajectory instability intensity (0–1) at the time of this turn.
trajectory_state: TrajectoryStateTrajectory controller state at the time of this turn.
clarity: f32Was the user request specific enough? (0=vague, 1=precise) Derived from: message length, symbol count, and subsequent correction rate.
context_freshness: f32Is the session context still coherent / fresh? (0=stale/overloaded, 1=fresh) Derived from: token cache-read ratio (compaction signal) and frustration slope. Drops when context is being squeezed or the agent starts showing confusion.
verification_rigor: f32Were results verified after code changes? (0=unverified, 1=rigorously verified) Derived from: presence of tool outcome strings (build/test pass/fail) in the exchange.
decision_progress: f32Did this turn move the task forward? (0=stalled/regressed, 1=clear progress) Derived from: decision text change and symbol set evolution vs prior capsule.
scope_discipline: f32Did scope stay stable? (0=scope creep/drift, 1=focused) Derived from: symbol set growth rate across recent history, category stability.
flags: Vec<String>Derived behavioral flags, e.g. “retry_loop”, “session_heavy”, “scope_shift”, “unverified_claim”, “needs_clarification”, “blind_acceptance”.
outcome_hint: StringNear-term outcome: “progressed” | “stalled” | “regressed” | “unclear”
cost_acceleration: f32Rolling slope of tokens_input over the last 3 turns, normalised 0–1.
High value = token spend is accelerating without corresponding progress.
Computed only when usage metadata is available; 0 otherwise.
Formula: (tokens_input[N] - tokens_input[N-2]) / tokens_input[N-2], clamped to [0, 1]. Values > 0.5 indicate meaningful acceleration.
evidence: Vec<String>Compact, auditable facts explaining why scores are what they are. e.g. “no test/build outcome found after 3 code-touching turns”
