* fix(#1520): randomize mktemp temp paths on BSD/macOS (XXXXXX must be path-final) BSD/macOS mktemp only substitutes the XXXXXX template when it is the final path component. Templates like `...-XXXXXX.json` / `gsd-pr-body.XXXXXX.md` return a LITERAL `XXXXXX` path (no randomization) on macOS, so concurrent workflow runs collide on the same temp manifest/body file — one run can overwrite or consume another's. Reproduced on macOS: the second call to the suffixed template fails `mkstemp: File exists`. Fix: use a suffixless `XXXXXX` template (so it IS the final component), then rename to add the intended extension — portable across BSD + GNU userlands, no GNU-only `--suffix` flag. Empty-file-then-write semantics are preserved at every site. Affected workflow temp files: - execute-phase.md: gsd-worktree-wave-*.json (wave worktree manifest) - quick.md: gsd-quick-worktree-*.json - spec-phase.md: edge-probe-reqs-*.json - ship.md: gsd-pr-body-*.md - profile-user.md: gsd-profile-answers-*.json, gsd-profile-analysis-*.json The execute-phase.md edit uses a compact intermediate var + trailing comment to stay under the ADR-857 phase-6 size ceiling (93166); regenerated the workflow size baseline accordingly. Validated on macOS: 20 concurrent calls yield 20 unique randomized paths.

Fails on the six pre-fix instances and passes on the fix, and locks the copy-paste-prone idiom out of future workflows. Mirrors the bug-637 hardcoded-$HOME workflow guard. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(#1520): rename regression test to fix- prefix (regression-test-names lint) New tests/bug-NNNN-*.test.cjs files are banned by the lint-regression-test-names ratchet; use the fix- prefix (matches the fix-1445 precedent). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(#1520): add issue ref to allow-test-rule exemption (ADR-456 lint) lint-allow-test-rule-refs requires every new `allow-test-rule:` comment to carry a #NNN reference (don't allowlist). Add (#1520) to the source-text exemption. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(#1520): abort touched mktemp chains on failure (|| exit 1) Per review: the VAR=$(mktemp …) && mv … && VAR=… chains dropped the issue's suggested failure guard. If mktemp fails, $VAR is empty and the subsequent mv/write lands on an unintended relative path. Add `|| exit 1` to all six touched chains so a mktemp failure aborts the snippet. Regenerated the workflow size baseline for the slightly longer lines. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore(#1520): rebase onto next — regen size baseline + describe rename Resolve the workflow-size-baseline.json conflict from next advancing by regenerating from the current workflow sizes. Also rename the test describe from `bug #1520` to `#1520` (the file uses the fix- prefix) per review nit. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(#1520): harmonize profile-user mktemp to ${TMPDIR:-/tmp} (review nit) The two profile-user.md temp sites this PR already rewrites kept a hardcoded /tmp while the four sibling workflows use ${TMPDIR:-/tmp}. Harmonize for consistency and macOS-correctness (some sandboxes have no writable /tmp). Regenerated the workflow size baseline.

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.
