* test(#3255): updateTableCell reaches a later table when the first lacks the column A ## Traceability section holding a summary table (no Status) above the requirement table (with Status) made updateTableCell bind to the first table and return 'unknown column: Status', so requirements.mark-complete left the row at Pending. Add a failing-first regression at the primitive. RED — fails on next; fix follows. * fix(#3255): updateTableCell scans for the table carrying the requested column updateTableCell bound to the FIRST GFM table in the scoped text and returned 'unknown column' if that table lacked the column — so a ## Traceability section holding a phase-summary table above the requirement table never reached the requirement table, and requirements.mark-complete left the row at Pending while reporting table_unmatched (the #2140 silent-divergence class one level deeper, flagged but not closed by the #2245 cross-section scoping fix). Scan candidate table headers and pick the first VALID table (delimiter + matching column count) whose columns include the requested column. Single-table behaviour is byte-identical (the one table carries the column). Error semantics preserved: no table -> 'no table found'; valid table without the column -> 'unknown column'; lone malformed table keeps its specific reason. Also fixes the derived hasRow/doneTable reasoning, which probes via the same call. * chore(#3255): add changeset fragment * chore(#3255): backfill changeset PR number (#3377) --------- Co-authored-by: sim <sim@local>
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:
- 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, 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.
