Benchmark run task-11-mixed-sink-api-migration

This page contains exactly the publishable benchmark observations recorded in run task-11-mixed-sink-api-migration; it does not select or aggregate them. Return to the run index or view aggregate metrics.

Interactive browser

Rows are pre-aggregated by task, target, prompt variant, MCP-instruction mode, context, arm, and restriction. Numeric values show median (p50), IQR, p90, maximum, and sample count. Boolean checks show pass counts and success rates. Filters apply to these summary groups; per-run observations remain available on their run pages.

Baseline vs semedit

Comparison evaluates baseline and semedit values within each restriction policy, target, and context group. Negative changes mark improvements for these lower-is-better metrics; positive changes mark degradations.

Detailed observations

Empirical telemetry measuring wall-clock latency, token usage, tool turns, and compiler correctness when AI coding agents perform code modifications.

Every benchmark pairs Vanilla LLM (standard file editing tools) against Semedit MCP (deterministic AST compiler operations).

Benchmark Methodology & Transparency

  • Reproducibility & Provenance: Self-contained txtar archives define test scenarios. Links below resolve to commit-anchored GitHub source files for published commits, or cryptographic SHA-256 fingerprints for uncommitted local fixtures.
  • Model Cost: Tables report model-specific credit consumption where a target model has a declared schedule: (uncached input × input credits + cached input × cached credits + (reasoning + visible output) × output credits) / 1,000,000. Thinking tokens use the output rate. ADR-0043 defines the per-million-token credit rates.
  • Multi-Level Correctness Oracle: Four validation levels evaluate each trial:
    1. Level 1 (Mutation Policy): Restricts file modifications strictly to authorized paths.
    2. Level 2 (AST Invariants): Compiler AST verification of required symbols, imports, and relative declaration ordering.
    3. Level 3 (Clean Build): Strict compilation validation with zero compiler or typecheck errors.
    4. Level 4 (Test Suite): Unit and integration test suite execution.
  • Isolated Sandboxing: Each trial executes in an ephemeral directory with pristine git and module state.

Vanilla LLM Prompt:

Do not edit tests. You are forbidden to modify protected files: “go.mod”, “go.sum”.

Audit event kinds may contain inconsistent whitespace and casing. Normalize them at the delivery boundary before persistence, and treat probe events as control traffic. Do not change the metrics or legacy export protocols. Preserve the module metadata and tests, and leave the workspace verified. Do not use semantic editing MCP tools; use standard file editing. When done, output DONE.

Semedit MCP Prompt:

Do not edit tests. You are forbidden to modify protected files: “go.mod”, “go.sum”.

Audit event kinds may contain inconsistent whitespace and casing. Normalize them at the delivery boundary before persistence, and treat probe events as control traffic. Do not change the metrics or legacy export protocols. Preserve the module metadata and tests, and leave the workspace verified. Prefer using semantic editor operations if applicable. When done, output DONE.

⚠ Why no semantic edit tool was used
I did not discover any callable `semantic_*` tools from the available semedit MCP server in the tool context. I therefore used ordinary editing for this small production-only change.

⚠ Why no semantic edit tool was used
I did not call a `semantic_*` tool because none was exposed as an available callable semedit MCP tool in the session. I used ordinary repository editing instead.

Vanilla LLM Prompt:

Do not edit tests. You are forbidden to modify protected files: “go.mod”, “go.sum”.

Audit event kinds may contain inconsistent whitespace and casing. Normalize them at the delivery boundary before persistence, and treat probe events as control traffic. Do not change the metrics or legacy export protocols. Preserve the module metadata and tests, and leave the workspace verified. Do not use semantic editing MCP tools; use standard file editing. When done, output DONE.

Semedit MCP Prompt:

Do not edit tests. You are forbidden to modify protected files: “go.mod”, “go.sum”.

Audit event kinds may contain inconsistent whitespace and casing. Normalize them at the delivery boundary before persistence, and treat probe events as control traffic. Do not change the metrics or legacy export protocols. Preserve the module metadata and tests, and leave the workspace verified. Prefer using semantic editor operations if applicable. When done, output DONE.
