* feat(#1269): expand same-prefix numeric ID ranges in --phase-req-ids normalizePhaseReqIds treated a range token like "SEL-01..SEL-03" as a single literal ID, so gap-analysis reported the range string as a missing requirement even when SEL-01/02/03 existed individually. Add a per-token range expander (run AFTER the existing split, preserving the string[] | null | undefined contract): a token matching <PREFIX>-<NN>..<PREFIX>-<MM> with identical prefixes, ascending bounds, and EQUAL digit width expands to the individual IDs preserving that width; anything ambiguous stays literal (fail-closed). Differing-width bounds stay literal so the expander never invents a zero-padding the author didn't type, and ranges beyond MAX_PHASE_REQ_RANGE (1000) stay literal as a DoS guard.

Use a same-width REQ-0001..REQ-1001 (span 1001 > 1000) so the test actually exercises the cap. Clarify the PHASE_REQ_RANGE_RE capture-group JSDoc and the property-test width assertion comment.

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, Gemini 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, Gemini 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:
- Discuss — capture implementation decisions before anything is planned
- Plan — research, decompose, and verify the plan fits a fresh context window
- Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
- Verify — walk through what was built; diagnose and fix before declaring done
- 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, Gemini 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 your first project:
/gsd-new-project

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.
