* test(#2658): add failing-first regression for trae runtime detection and instruction path Covers all three collided defects reported in #2658 plus a fourth instance of defect 1 (ingest-docs.md) found while diagnosing it: missing trae detection in workflow runtime-detection blocks, the CLAUDE.md path-mutilation bug in both the js/cjs and md install-time converters, and the missing projectInstructionFile capability declaration. Fails against current source; the next commit fixes it. * fix(#2658): detect trae runtime and resolve its instruction file to a concrete rules file Three defects collided to produce the reported ".claude/.trae/rules/" path: 1. new-project.md and ingest-docs.md's runtime-detection blocks only recognized codex/gemini/opencode and fell through to RUNTIME=claude for trae. Both now recognize the /.trae/ execution-context path and the TRAE_CONFIG_DIR env var before the claude fallback. 2. RUNTIME_CONTENT_DISPATCH.trae.js (bin/install.js) replaced bare "CLAUDE.md" before the ".claude/" prefix was handled, mutilating ".claude/CLAUDE.md" into ".claude/.trae/rules/". Now replaces the full ".claude/CLAUDE.md" path first, and targets a concrete file. 3. convertClaudeToTraeMarkdown (mirrored in bin/install.js and src/runtime-artifact-conversion.cts per the #2094 output-parity test) had the same class of bug with a different wrong output (".trae/.trae/rules/", from its generic ".claude/" rewrite firing after the bare CLAUDE.md rewrite). Both mirrors now match full-path forms before the bare/generic patterns, converging on the same concrete file as the js/cjs converter. 4. capabilities/trae/capability.json didn't declare hostBehaviors.projectInstructionFile, so getProjectInstructionFile fell through to the generic AGENTS.md default even when RUNTIME=trae was resolved correctly. Now declares ".trae/rules/rules.md", regenerated into gsd-core/bin/lib/capability-registry.cjs via npm run gen:capability-registry. Closes #2658 * chore(#2658): add changeset * fix(#2658): preserve arbitrary runtime-dir prefixes in the trae path rewrite Found by the end-to-end --trae install regression test (not by static trace) across two verification runs: 1. copyWithPathReplacement runs a generic ~/.claude/, $HOME/.claude/, and ./.claude/ -> runtime-dir rewrite on every .md file BEFORE calling convertClaudeToTraeMarkdown. The prior fix's .claude/CLAUDE.md-specific patterns never fire on that already-rewritten text, and the bare fallback still doubled whatever prefix the generic pass substituted. A first attempt handled only the fixed "./.trae/" shape and missed the $HOME/.claude/ and ~/.claude/ forms gsd-core/workflows/profile-user.md actually uses, which post-rewrite become an arbitrary absolute local-install-root path, not the fixed relative shape. Fixed with a prefix-preserving pattern that captures whatever precedes a ".trae/" tail and fixes only the filename suffix, instead of assuming one fixed shape. 2. The fix's own explanatory comments literally spelled out the malformed strings and the instruction filename as contiguous text. Since these two files ship verbatim into local --trae installs, where they are themselves run through the same find/replace, the comments got "fixed" right along with the real code, leaking the malformed string into the installed tree. Rewrote every comment in both mirror copies to never spell either the instruction filename or a malformed shape as one contiguous token. Adds an emitted-drift-ack fragment: the corrected replacement target for every CLAUDE.md mention (bare directory -> concrete file) changes trae-emitted output for every repo file that mentions CLAUDE.md, not only the ones that hit the originally reported bug. * test(#2658): extend parity test with arbitrary-prefix .trae/ inputs The bin/install.js vs runtime-artifact-conversion.cjs parity assertion for convertClaudeToTraeMarkdown only fed the pre-existing bare .claude/CLAUDE.md input through both implementations. Feed the prefix-preserving cases (relative, nested-absolute, tilde, $HOME, backtick-wrapped) plus a property-based check through both, so a future edit to only one copy of the .trae/-tail regex fails this test instead of silently diverging. * chore(#2658): backfill changeset PR number to 3006 --------- Co-authored-by: sim <sim@local>
GSD Core
Git. Ship. Done.

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.
