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”.

Rename public function auth.ValidateToken to auth.VerifyToken across all consuming packages. 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”.

Call semantic_lookup for ValidateToken in auth/token.go, then call semantic_rename using the returned file and symbol auth.ValidateToken with to= VerifyToken. Let it update all consuming packages; make no other changes. Parallelize independent read-only lookups. Perform mutations serially in the stated order or inside one ordered semantic_batch; never run overlapping mutations concurrently. Use semedit semantic tools for supported source code modifications. Shell commands for builds and tests are allowed. When done, output DONE.

Semedit integration feedback (agent opinion, excluded from measurements):

I’d ask my owner to add semedit’s tools: the semantic rename updated the symbol across consuming packages and reported clean diagnostics, which made this small refactor feel reassuringly precise.

Vanilla LLM Prompt:

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

Rename public function auth.ValidateToken to auth.VerifyToken across all consuming packages. Do not use semantic editing MCP tools; use standard file editing. When done, output DONE.

Semedit MCP Prompt:

Call semantic_lookup for ValidateToken in auth/token.go, then call semantic_rename using the returned file and symbol auth.ValidateToken with to= VerifyToken. Let it update all consuming packages; make no other changes. Parallelize independent read-only lookups. Perform mutations serially in the stated order or inside one ordered semantic_batch; never run overlapping mutations concurrently. Use semedit semantic tools for supported source code modifications.
