* fix(#381): make gsd_run launcher reachable in fresh-shell-per-block runtimes On runtimes that execute each fenced bash block in a separate shell process (e.g. Claude Code — documented behavior: each Bash command is a separate process; inline shell functions and exported vars do not persist between calls), the once-per-file gsd_run() function was undefined in every block after the preamble block, and the call was swallowed by `2>/dev/null || echo "{}"` into silent empty state. Fix (budget-neutral session-level resolution): - Ship gsd-core/bin/gsd_run, a POSIX sh wrapper that symlink-resolves its own location and execs the co-located gsd-tools.cjs. Exposed on PATH via the npm `bin` field (global installs) and shipped to local installs via the recursive gsd-core/ copy. - The per-file launcher preamble now appends `export PATH='<bindir>':"$PATH"` to the file named by $CLAUDE_ENV_FILE (Claude Code's documented env-persistence mechanism) so later fresh-shell blocks resolve gsd_run from PATH. Guarded as a strict no-op when CLAUDE_ENV_FILE is unset; the inline gsd_run() definition remains the fallback for all other runtimes. The single-quoted dir neutralizes shell metacharacters at source time. - Propagated via scripts/sync-runtime-launcher.cjs to all launcher-using files. - XL workflow byte budget 93000 -> 93200 (the ~130B clause pushes plan-phase.md to 93135; legitimate content growth, ratchet-up per #717). Regression tests (I)/(J) in runtime-launcher-parity.test.cjs cover wrapper delegation and end-to-end PATH persistence (sourcing the env file with a space-bearing install path). Known limitation: an install path containing a literal single-quote yields a malformed env-file line and falls back to the status quo (no regression); rare on sanitized home directories.

The env-file content assertions (the fix's actual cross-platform logic) still run on every platform; only the final source-and-execute sub-step is gated to non-win32. Global installs on Windows are covered by npm's generated bin shim.

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.
