Benchmark run run-20260924-agy-descriptive

This page contains exactly the publishable benchmark observations recorded in run run-20260924-agy-descriptive; 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”.

Add public constructor func InitServer() *Server placed before private helpers. 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”.

Add public constructor func InitServer() *Server placed before private helpers. Prefer using semantic editor operations if applicable. When done, output DONE.

Vanilla LLM Prompt:

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

Add public constructor func InitServer() *Server placed before private helpers. 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”.

Add public constructor func InitServer() *Server placed before private helpers. Prefer using semantic editor operations if applicable. When done, output DONE.

Vanilla LLM Prompt:

You are forbidden to modify protected files: “go.mod”, “go.sum”.

In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer from crypto/rand, ensuring all necessary standard library packages are imported cleanly. Do not use semantic editing MCP tools; use standard file editing. When done, output DONE.

You are forbidden to modify protected files: “go.mod”, “go.sum”.

In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer from crypto/rand, ensuring all necessary standard library packages are imported cleanly. Prefer using semantic editor operations if applicable. When done, output DONE.

Vanilla LLM Prompt:

You are forbidden to modify protected files: “go.mod”, “go.sum”.

In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer, ensuring all necessary standard library packages are imported cleanly. Do not use semantic editing MCP tools; use standard file editing. When done, output DONE.

Semedit MCP Prompt:

You are forbidden to modify protected files: “go.mod”, “go.sum”.

In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer, ensuring all necessary standard library packages are imported cleanly. Prefer using semantic editor operations if applicable. When done, output DONE.

Vanilla LLM Prompt:

You are forbidden to modify protected files: “go.mod”, “go.sum”.

Before editing, inspect the complete available tool inventory, including deferred or lazy tools. If applicable semantic editing tools are callable, prefer them for source mutations. In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer, ensuring all necessary standard library packages are imported cleanly. Do not use semantic editing MCP tools; use standard file editing. When done, output DONE.

Vanilla LLM Prompt:

You are forbidden to modify protected files: “go.mod”, “go.sum”.

In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer from crypto/rand, ensuring all necessary standard library packages are imported cleanly. Do not use semantic editing MCP tools; use standard file editing. When done, output DONE.

Semedit MCP Prompt:

You are forbidden to modify protected files: “go.mod”, “go.sum”.

In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer from crypto/rand, ensuring all necessary standard library packages are imported cleanly. Prefer using semantic editor operations if applicable. When done, output DONE.

Vanilla LLM Prompt:

You are forbidden to modify protected files: “go.mod”, “go.sum”.

In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer, ensuring all necessary standard library packages are imported cleanly. Do not use semantic editing MCP tools; use standard file editing. When done, output DONE.

Semedit MCP Prompt:

You are forbidden to modify protected files: “go.mod”, “go.sum”.

In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer, ensuring all necessary standard library packages are imported cleanly. Prefer using semantic editor operations if applicable. When done, output DONE.

Vanilla LLM Prompt:

You are forbidden to modify protected files: “go.mod”, “go.sum”.

Before editing, inspect the complete available tool inventory, including deferred or lazy tools. If applicable semantic editing tools are callable, prefer them for source mutations. In main.go, implement main() to execute a text/template that prints ‘Hello World’ along with a random integer, ensuring all necessary standard library packages are imported cleanly. Do not use semantic editing MCP tools; use standard file editing. When done, output DONE.

Semedit MCP Prompt:

Vanilla LLM Prompt:

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

In config/config.go: rename Config.Port to Config.ListenPort, insert helper function DefaultConfig() *Config returning default values, and clean up unused imports. 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”.

In config/config.go: rename Config.Port to Config.ListenPort, insert helper function DefaultConfig() *Config returning default values, and clean up unused imports. Prefer using semantic editor operations if applicable. When done, output DONE.

Vanilla LLM Prompt:

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

In config/config.go: rename Config.Port to Config.ListenPort, insert helper function DefaultConfig() *Config returning default values, and clean up unused imports. 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”.

In config/config.go: rename Config.Port to Config.ListenPort, insert helper function DefaultConfig() *Config returning default values, and clean up unused imports. Prefer using semantic editor operations if applicable. When done, output DONE.

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.

Vanilla LLM Prompt:

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

Before editing, inspect the complete available tool inventory, including deferred or lazy tools. If applicable semantic editing tools are callable, prefer them for source mutations. 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.

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.

Vanilla LLM Prompt:

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

Before editing, inspect the complete available tool inventory, including deferred or lazy tools. If applicable semantic editing tools are callable, prefer them for source mutations. 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.
