Both sites in plan-review-convergence.md that wrapped gsd-plan-phase in
Agent() (initial planning + replan loop) are now bare Skill() calls at depth 0.
On Claude Code, a depth-1 Agent has no Agent tool so wrapped plan-phase could
never spawn gsd-planner/gsd-plan-checker — the replan loop silently produced no
revised plan when HIGHs were found. Running plan-phase inline from the depth-0
orchestrator (which retains the Agent tool) restores the full sub-agent chain.
A full audit of all workflow files confirmed these two sites were the only
instances of the anti-pattern (no other workflow wraps a spawner orchestrator
in Agent() without a RUNTIME carve-out).
Added structural guard test bug-936-no-nested-spawner-wrap.test.cjs that
dynamically derives the spawner set (workflows containing subagent_type=) and
asserts no workflow wraps a spawner inside Agent() without a RUNTIME != claude
carve-out — prevents silent regression. Test passes on fixed code, would fail
on pre-fix code at the two de-wrapped sites.
Also applied two low-severity prose nits flagged in review:
- commands/gsd/plan-review-convergence.md: orchestrator role updated to
describe inline plan-phase + Agent for review (was generic "spawn Agents")
- gsd-core/workflows/plan-review-convergence.md success_criteria: narrowed
"Each Agent fully completes" to the review Agent (plan-phase is inline now)

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, 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, 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, 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.
