From c608af1eb9ffed45f11665f6f3c34ec834217994 Mon Sep 17 00:00:00 2001 From: Your Name Date: Tue, 1 Sep 2026 14:23:31 +0000 Subject: [PATCH 1/3] feat(evaluator): add evaluator contract extension with model routing Implements the standard evaluator result contract proposed in #4290. This is a provider-neutral protocol for extensions that evaluate artifact quality between Spec-Driven Development phases. Extension (extensions/evaluator/): - JSON Schema for evaluator results (6 outcomes, 14 finding kinds, 5 evidence kinds) - 4 commands: run, compose, report, route - 3 scripts: Python, Bash, PowerShell (parity across all runtimes) - 4 lifecycle hooks: after_specify, after_plan, after_tasks, after_implement - Model routing: recommends budget/standard/premium tier per phase - Composition: strict/majority/optimistic strategies with contradiction detection Tests (tests/extensions/evaluator/): - 70 tests: layout, catalog, install, compose logic, benchmarks, model routing - 0 regressions against full test suite (4296 passed) Benchmarks (benchmarks/evaluator/): - SDD workflow simulation with 8 evaluators across 4 phases - Composition at scale: up to 20 evaluators x 100 findings (2000 total) - Report generation in all 5 formats (terminal, markdown, JSON, CI, gate) - Token-economic simulation with Monte Carlo (500 runs/scenario) - Portfolio approach: budget for routine, premium for critical decisions Catalog: registered as bundled extension in extensions/catalog.json Assisted-by: GitHub Copilot (model: deepseek-v4-pro, autonomous) --- benchmarks/evaluator/run_benchmarks.py | 1032 +++++++++++++++++ benchmarks/evaluator/token_economics.py | 830 +++++++++++++ extensions/catalog.json | 18 + extensions/evaluator/README.md | 166 +++ .../commands/speckit.evaluator.compose.md | 156 +++ .../commands/speckit.evaluator.report.md | 120 ++ .../commands/speckit.evaluator.route.md | 155 +++ .../commands/speckit.evaluator.run.md | 162 +++ extensions/evaluator/extension.yml | 86 ++ .../schemas/evaluator-result.schema.json | 318 +++++ .../evaluator/scripts/bash/compose-results.sh | 149 +++ .../scripts/powershell/compose-results.ps1 | 178 +++ .../scripts/python/compose_results.py | 397 +++++++ .../templates/evaluator-result-template.json | 45 + tests/extensions/evaluator/__init__.py | 0 tests/extensions/evaluator/test_benchmarks.py | 387 +++++++ .../evaluator/test_compose_results.py | 441 +++++++ .../evaluator/test_evaluator_extension.py | 330 ++++++ 18 files changed, 4970 insertions(+) create mode 100644 benchmarks/evaluator/run_benchmarks.py create mode 100644 benchmarks/evaluator/token_economics.py create mode 100644 extensions/evaluator/README.md create mode 100644 extensions/evaluator/commands/speckit.evaluator.compose.md create mode 100644 extensions/evaluator/commands/speckit.evaluator.report.md create mode 100644 extensions/evaluator/commands/speckit.evaluator.route.md create mode 100644 extensions/evaluator/commands/speckit.evaluator.run.md create mode 100644 extensions/evaluator/extension.yml create mode 100644 extensions/evaluator/schemas/evaluator-result.schema.json create mode 100644 extensions/evaluator/scripts/bash/compose-results.sh create mode 100644 extensions/evaluator/scripts/powershell/compose-results.ps1 create mode 100644 extensions/evaluator/scripts/python/compose_results.py create mode 100644 extensions/evaluator/templates/evaluator-result-template.json create mode 100644 tests/extensions/evaluator/__init__.py create mode 100644 tests/extensions/evaluator/test_benchmarks.py create mode 100644 tests/extensions/evaluator/test_compose_results.py create mode 100644 tests/extensions/evaluator/test_evaluator_extension.py diff --git a/benchmarks/evaluator/run_benchmarks.py b/benchmarks/evaluator/run_benchmarks.py new file mode 100644 index 0000000000..eb9ca93ec3 --- /dev/null +++ b/benchmarks/evaluator/run_benchmarks.py @@ -0,0 +1,1032 @@ +"""Comprehensive benchmark suite for the Evaluator Contract extension. + +Simulates a full Spec-Driven Development workflow with multiple evaluators +at each phase, measures composition correctness at scale, and benchmarks +report generation across all formats. + +Benchmarks: + 1.
