Build Efficiency exit conditions

BUILD-TOKEN-BUDGET-PER-FEATURE

Total tokens consumed to complete the feature stays within the declared per-feature ceiling.

BUILD-COST-CEILING-USD

Cumulative model spend for the build does not exceed the configured dollar cap.

BUILD-INPUT-TOKEN-CAP

Prompt (input) tokens across the build stay under the input-token allowance.

BUILD-OUTPUT-TOKEN-CAP

Generated (output) tokens across the build stay under the output-token allowance.

BUILD-COST-PER-TASK-BOUNDED

No single task exceeds its allotted share of the feature cost budget.

BUILD-BUDGET-BURN-RATE

Spend accrues no faster than the planned burn rate for the elapsed build progress.

BUILD-COST-REGRESSION-GUARD

Feature build cost does not regress beyond a threshold versus the prior baseline for comparable work.

BUILD-OVERAGE-HALTS-BUILD

The build stops and reports rather than silently continuing once a hard budget limit is hit.

BUILD-CHEAP-MODEL-FOR-MECHANICAL

Mechanical steps (formatting, boilerplate, renames) are routed to the designated low-cost model.

BUILD-STRONG-MODEL-FOR-HARD

Reasoning-heavy steps are routed to the designated high-capability model.

BUILD-EFFORT-LEVEL-MATCHED

Each step’s requested effort/reasoning level matches the difficulty class assigned to it.

BUILD-NO-OVERPOWERED-ROUTING

Trivial steps are not sent to premium models when a cheaper model meets the quality bar.

BUILD-ROUTING-RULES-DECLARED

A model-routing policy mapping step classes to models exists and is applied.

BUILD-FALLBACK-MODEL-BOUNDED

Escalation to a stronger model on failure occurs only after cheaper attempts and within a capped count.

BUILD-MODEL-DOWNSHIFT-WHEN-SAFE

Steps proven mechanical mid-build are downshifted to the cheaper model on subsequent runs.

BUILD-ROUTING-DECISIONS-LOGGED

Every step records which model handled it and the routing rationale.

BUILD-RETRY-COUNT-BOUNDED

The number of retries for any failing step stays under the configured maximum.

BUILD-CONVERGE-WITHIN-N

The build reaches a passing state within the declared maximum number of attempts.

BUILD-NO-INFINITE-LOOP

No step re-attempts indefinitely; a hard attempt cap terminates non-converging loops.

BUILD-DIMINISHING-RETURNS-STOP

Iteration halts when successive attempts stop reducing the failing-condition count.

BUILD-OSCILLATION-DETECTED

The build detects and breaks cycles where edits alternate between two failing states.

BUILD-PROGRESS-PER-ATTEMPT

Each retry demonstrably changes the artifact or the outcome rather than repeating identically.

BUILD-ATTEMPT-BUDGET-PER-PHASE

Per-phase attempt counts respect their individual limits, not just the global cap.

BUILD-STALL-ESCALATES

A stalled step escalates to a stronger model or human rather than looping at the same tier.

BUILD-PROMPT-CACHE-UTILIZED

Stable prompt prefixes are served from the provider prompt cache above the target hit rate.

BUILD-CACHE-KEY-STABLE

Cacheable prefixes are held byte-stable so cache entries are not needlessly invalidated.

BUILD-INCREMENTAL-REUSE

Unchanged modules reuse prior build outputs instead of being regenerated.

BUILD-DEPENDENCY-CACHE-HIT

Resolved dependencies and toolchain artifacts are served from cache across runs.

BUILD-ARTIFACT-CACHE-REUSED

Previously produced compiled or generated artifacts are reused when their inputs are unchanged.

BUILD-NO-REDUNDANT-REGEN

The same artifact is not regenerated twice within a build when its inputs did not change.

BUILD-CACHE-INVALIDATION-SCOPED

Cache invalidation is limited to entries whose inputs actually changed.

BUILD-MEMOIZED-SUBRESULTS

Repeated identical sub-queries within the build reuse a memoized result.

BUILD-NO-WHOLE-FILE-DUMP

Prompts include only the relevant spans of a file rather than dumping entire files.

BUILD-CONTEXT-WINDOW-UTILIZATION

Context supplied per step stays within the target fraction of the model’s window.

BUILD-RETRIEVAL-SCOPED

Only files and symbols relevant to the current step are retrieved into context.

BUILD-NO-DUPLICATE-CONTEXT

The same content is not included multiple times within a single prompt.

BUILD-SUMMARY-OVER-RAW

Large histories are compacted to summaries rather than carried verbatim across steps.

BUILD-CONTEXT-GROWTH-BOUNDED

Accumulated context does not grow unbounded across a multi-step task.

BUILD-STALE-CONTEXT-EVICTED

Context no longer relevant to remaining steps is evicted before further generation.

BUILD-PARALLEL-WHERE-SAFE

Independent tasks with no shared dependencies are executed concurrently.

BUILD-NO-UNSAFE-PARALLEL

Tasks with data or ordering dependencies are not run in parallel.

BUILD-TIME-BUDGET-PER-PHASE

Each build phase completes within its allotted wall-clock time budget.

BUILD-TOTAL-WALLCLOCK-CAP

End-to-end build duration stays under the overall time ceiling.

BUILD-CONCURRENCY-LIMIT-RESPECTED

The number of simultaneous model or tool calls stays within the configured limit.

BUILD-PHASE-TIMEOUT-HALTS

A phase exceeding its time budget halts and reports rather than running unbounded.

BUILD-CRITICAL-PATH-BOUNDED

The dependency critical path length stays within its planned maximum.

BUILD-ONLY-AFFECTED-RECHECKED

Only exit conditions touched by the latest change are re-evaluated, not the full suite.

BUILD-NO-REVERIFY-UNCHANGED

Artifacts unchanged since their last passing check are not re-verified.

BUILD-DISCARDED-WORK-FLAGGED

Generated output later thrown away without use is detected and reported as waste.

BUILD-DEAD-BRANCH-PRUNED

Abandoned exploration branches are pruned rather than continued to completion.

BUILD-NO-SPECULATIVE-OVERBUILD

Work not required by any pending exit condition is not generated.

BUILD-REDUNDANT-STEP-ELIDED

Steps whose outputs are already satisfied by prior results are skipped.

BUILD-INCREMENTAL-CHECK-SCOPE

Re-verification scope is computed from the change’s dependency closure, not the whole project.

BUILD-WASTE-RATIO-BOUNDED

The ratio of discarded to committed work stays below the configured waste threshold.
