Tom Boucher 4f32209f78 enhance(#3267): reduce handleEvaluate complexity below refactor-trigger's own threshold (#3978)
* fix(#3267): reduce handleEvaluate complexity below refactor-trigger's own threshold

handleEvaluate scored 26 (then 21 after later #3261 commits) against the
complexity-triggered-refactor feature's own default threshold of 15. Extracts
the read-and-analyze loop (analyzeTouchedFiles) and the artifact/baseline/
ledger write path (finalizeEvaluation) into named helpers, per the issue's
suggested direction. Behavior-preserving: every existing test in
tests/refactor-trigger-cli.test.cjs is unchanged, and every degrade-path
reason code (REFACTOR_INVALID_PHASE, REFACTOR_GIT_UNAVAILABLE,
REFACTOR_NO_TOUCHED_FILES, REFACTOR_FILE_UNREADABLE,
REFACTOR_ANALYZER_UNSUPPORTED, REFACTOR_ANALYZER_UNPARSEABLE,
REFACTOR_BASELINE_WRITE_FAILED, REFACTOR_STRICT_NOT_ENFORCING) keeps its
current value and emission path.

The four complexity-trigger.cts lexer functions (scanFunctions,
stripLiterals, skipTypeExpr, skipGenericParamList) are deliberately left
untouched, per ADR-1953 D5 — they are a hand-rolled lexer state machine,
densely branchy by construction, and refactoring them to lower the metric
would be exactly the "split a coherent function to satisfy a metric"
behavior D5 exists to prevent.

Closes #3267

GSD Core

Git. Ship. Done.

English · Português · 简体中文 · 日本語 · 한국어

A light-weight meta-prompting, context engineering, and spec-driven development system for Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more.

What is GSD Core

GSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Antigravity CLI, Kimi CLI, Copilot, Cursor, and more) through a disciplined phase loop. It solves context rot — the quality degradation that accumulates as an AI fills its context window — by running all heavy research, planning, and execution work in fresh-context subagents while keeping your main session lean.


How it works

Each milestone repeats the same five-step loop, one phase at a time:

  1. Discuss — capture implementation decisions before anything is planned
  2. Plan — research, decompose, and verify the plan fits a fresh context window
  3. Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
  4. Verify — walk through what was built; diagnose and fix before declaring done
  5. Ship — create the PR, archive the phase, repeat for the next one

Quickstart

npx @opengsd/gsd-core@latest

The installer prompts for your runtime (Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally. The installer is required for cross-runtime compatibility — do not copy files from agents/ or commands/ directly.

On another runtime or without Node.js? See Install on your runtime.

Once installed, start a new project or onboard an existing repo:

/gsd-new-project   # greenfield project
/gsd-onboard       # existing codebase

New here? Follow Your first project for a guided walkthrough from install to first shipped phase, or Onboarding an existing codebase for brownfield setup.

Why it works

Most AI-coding setups fail at scale because context bloat silently degrades output quality, there is no shared memory between sessions, and nothing verifies that code actually works. GSD Core solves all three: heavy work runs in fresh subagents, structured artifacts like STATE.md and CONTEXT.md survive session boundaries, and the verify step walks through what was built and generates fix plans before a phase is declared done. See docs/explanation/context-engineering.md for the full reasoning.
