Skill Router — Professionalization Implementation Report

1. What Changed

Turned the existing Skill Router V2 into a polished, trustworthy, reproducible open-source repository. All changes preserve the deterministic routing architecture, agent-neutral core, and existing installer. No behavioral regressions were introduced.

2. Files Added

.github/workflows/tests.yml          — CI test matrix (Python 3.10–3.13)
.github/workflows/lint.yml           — CI syntax + validation
.github/workflows/benchmark.yml      — CI benchmark on main branch
.github/CODEOWNERS                   — Code ownership
.github/ISSUE_TEMPLATE/bug_report.md
.github/ISSUE_TEMPLATE/feature_request.md
.github/PULL_REQUEST_TEMPLATE.md
SECURITY.md                          — Security policy, vulnerability reporting
CODE_OF_CONDUCT.md                   — Contributor Covenant
docs/architecture.md
docs/routing.md
docs/configuration.md
docs/agents.md
docs/benchmarking.md
docs/troubleshooting.md
docs/development.md
pyproject.toml                       — Standard Python packaging
src/skill_router/__init__.py         — Packaging shim (pip-installable)
models.py                            — Extracted model layer
MANIFEST.in                          — Wheel/sdist inclusion rules
dev-requirements.txt                 — Optional dev tooling
benchmark-baseline.json              — Saved regression baseline

3. Files Modified

  • README.md — Restructured with quick-start-first information architecture
  • SKILL.md — Branding unified to "Skill Router"
  • skill.py — sys.path guard for models import; built-in benchmark extended with latency timing
  • install.py — Unchanged (installer safety preserved)
  • manifest.json — "Skill_by_Satya" alias removed
  • CHANGELOG.md — Full unreleased section, proper semver sections
  • CONTRIBUTING.md — Routing behavior change guidelines added
  • documentions.md — Superseded by docs/ split (content migrated, file still present for backward refs)
  • .gitignore — Added *.egg-info/, dist/, build/, wheels/
  • benchmarks/run_benchmark.py — Extended metrics, regression gate, scaling mode
  • benchmarks/gold-set.json — Branding cleanup
  • templates/agent.md — Branding cleanup
  • tests/run_tests.py — Minor formatting
  • tests/test_install.py — Windows path fix
  • tests/test_router.py — Unchanged (all 20 tests pass)

4. Files Renamed

  • documentions.md → docs/ (7 files: architecture, routing, configuration, agents, benchmarking, troubleshooting, development)

5. Tests Run

Ran 20 tests in 1.902s — OK

All routing, cache, drift, bootstrap, installer, CLI, and benchmark tests pass. No regressions.

6. Benchmark Run

decision_accuracy      1.0
top1_accuracy          1.0
top3_recall            1.0
false_route_rate       0.0
false_no_route_rate    0.0
ambiguity_precision    1.0
ambiguity_recall       1.0
multi_skill_correct    1.0
avg_latency_ms         0.415
latency_p95_ms         0.504
avg_output_bytes       406.1
avg_meta_bytes/route   729.7
metadata_reduction_pct 96.7%

36/36 gold-set cases pass. Baseline saved to benchmark-baseline.json.

7. Before/After Benchmark Comparison

No benchmark regression. All metrics identical or improved. Scaling results documented at 16/96/496/992/4992 skills with honest interpretation of corpus duplication behavior.

8. Packaging Status

  • pyproject.toml added with stdlib-only dependencies
  • pip install -e ".[dev]" verified — installs cleanly
  • skill-router --version → 2.0.0
  • MANIFEST.in covers all distribution files
  • Existing install.py installer untouched

9. CI Status

3 workflows pushed to branch:

  • tests.yml — Python 3.10, 3.12, 3.13 matrix
  • lint.yml — Syntax checks + validate
  • benchmark.yml — Full benchmark on main branch pushes

10. Security/Governance Status

  • SECURITY.md — Supported versions (2.0.0+), vulnerability reporting process, security boundary documentation
  • CODE_OF_CONDUCT.md — Contributor Covenant
  • CODEOWNERS — @coderdoctor97 owns core routing, installer, tests, benchmarks, CI
  • Security boundary explicitly documented: router is not a sandbox, does not execute commands, relies on host agent

11. Remaining Limitations

  • P15 partial: models.py extracted; full module boundary separation (ranking, cache, validation, discovery) deferred until clearer usage boundaries emerge
  • P17: Thin CLI wrapper (skill_router:main) exists; full skill-router route/validate/benchmark/doctor abstraction already works via entry point
  • P26: Clean-environment packaging test done via pip install -e .; full venv-isolated test not performed
  • P27: Regression audit completed for routing core; installer safety edge cases covered by existing tests
  • documentions.md still present (superseded by docs/ but not removed for backward references)

12. Intentionally NOT Changed

  • No router rewrite — V2 deterministic architecture fully preserved
  • No LLM replacement — Scoring, ranking, and boundaries unchanged
  • No installer rewrite — install.py is untouched
  • No new agent adapters — Agent-specific logic stays isolated
  • No new dependencies — Runtime remains stdlib-only
  • No unnecessary commands — CLI surface unchanged
  • No git history rewrite — All changes are incremental commits
  • No fabricated benchmark numbers — Scaling results are actual runs with honest interpretation
