* test(3584): failing-first coverage for Plans-line trailing text roadmap update-plan-progress preserves trailing text only when the line begins with a canonical count token. Every other phrasing — including the TBD value the shipped template itself suggests — is replaced to end-of-line, and a sentence wrapping onto a second line has its first line deleted, leaving the continuation standing alone so the roadmap asserts something nobody wrote. Exit 0, updated:true, and the diff reads as a routine count bump. These tests fail on that, and pin the arms that must keep working: the template placeholder is still replaced, the #2853 token-plus-annotation path is unchanged, CRLF is neither stranded nor duplicated, and a run that leaves the line alone still updates the Progress table and checkboxes rather than becoming a no-op. * fix(3584): the verb owns the count token and nothing else RED proven at 105bdf7c: 7 failures — the preserving cases (freeform prose, wrapped continuation, TBD, CRLF) failed while the template-placeholder and #2853 token arms passed on base. The trailing-text guard fired only when the line began with a canonical count token: dropped the rest of the line whenever the regex's count group did not match. #2853 fixed end-of-line truncation on that one path only. The in-code comment justified the rest as 'the fresh-template bracketed placeholder or other freeform guidance, not user prose' — a heuristic that misreads ordinary human phrasing and destroys even TBD, the value the shipped template itself suggests at templates/roadmap.md:37. The sharper failure was the wrapped sentence: only the first line is inside the match, so the verb deleted line one and left line two standing alone, leaving the roadmap asserting something nobody wrote — at exit 0, updated:true, in a diff that reads as a routine count bump. Inverted the default into three arms. A real count token is rewritten with its annotation preserved (unchanged, #2853). A bracketed placeholder is detected POSITIVELY and replaced. Everything else — freeform prose, TBD, a wrapped sentence's first line, an empty value — returns the match untouched. That last arm resolves the wrapped case by construction: an untouched first line cannot orphan its continuation. Positive detection is the load-bearing part. Implemented as 'not a count token, therefore disposable', rows 1-3 come straight back; the detector instead asks whether the value IS a bracketed placeholder. Leaving the line alone does not make the verb a no-op: the phase checkbox, the Progress-table cells and the plan-checklist row still update in the same run, and that is asserted. CRLF is unaffected in every arm — the pattern's [^\r\n]* never consumes the \r, so it sits outside the match regardless of which arm runs. Fixes #3584 * fix(3584): detect the template placeholder by its text, not by its brackets Two defects in the arm-2 detector shipped in fc23e49e, both found in review. Finding A: isBracketedPlaceholder asked only whether the trimmed value was wrapped in [...]. Brackets are ordinary prose punctuation in a roadmap, so any hand-written bracketed note — '[Deferred pending re-scope]', '[blocked on #1234]' — was classified as the fresh-template placeholder and destroyed. That is the very defect #3584 is about, reintroduced one arm over. The detector now matches the placeholder's TEXT (/^\[\s*Number of plans\b[\s\S]*\]$/i), so it recognizes the shipped template value and its short form and nothing else. Finding B: the count group matched '\\d+\\s+plans' only. The plural is not the template's own output shape — templates/roadmap.md:62 ships '1 plan' — so a single-plan phase fell through every arm and its line froze permanently, never updating again. Widened to 'plans?'. This one was introduced by the arm-3 default: before it, the singular fell through to the old replace-everything path and at least stayed current. Cases 11-14 cover both: a bracketed human note preserved, the short placeholder still replaced, '1 plan' rewritten, and '1 plan (annotation)' rewritten with the annotation intact. Verified against the live binary, not just re-read. Also converted all 15 cases in this block from try/finally to t.after(), per CONTRIBUTING.md:356-370 which bans try/finally in test bodies. The existing #2853 block above is untouched — it is not in this change's scope and its conversion is not this fix's concern.

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

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.
