* chore(#2993): fragmentize plan-phase.md onto the fragment model Epic #1671 Phase 6.2. plan-phase.md is the largest workflow in the repo and carried zero markers; it was deferred out of the Phase 3 pilot for two reasons, both now dead. The 36-byte PRE_PHASE6 headroom was never the blocker it looked like — fragmentizing is net-negative on host source, so the trim is what creates the room. The --mvp interleaving was resolved by measurement in #2992 and no sub-line mechanism is built. - widen WHEN_VOCABULARY 14 -> 19 via a second coordinated ADR-1671 amendment: flag:--ingest, flag:--prd, flag:--research-phase, flag:--reviews, state:chunked-mode - state:chunked-mode is `--chunked` OR config workflow.plan_chunked, and that disjunction is resolved in the FACT, never in the grammar, so a compound condition never becomes an operator - parse the new flags on the plan-phase route; extract six gated bodies to gsd-core/workflows/plan-phase/steps/ behind manifest-gated stubs - prd-express-path.md was already extracted but read unconditionally; its wrapper is now gated, so the existing extraction finally pays off plan-phase.md 94,483 -> 87,575 bytes (cap 94,519): headroom goes from 36 bytes to 6,944. Also closes a surfaced docs gap: five real plan-phase flags (--chunked, --skip-ui, --bounce, --skip-bounce, --granularity) were documented in neither the argument-hint nor help. Making --chunked load-bearing without fixing its siblings would leave the defect class half-open. Refs #2993 * fix(#2993): forward flags to the init bundle so section gating actually fires Blocker found by the correctness review, confirmed directly, and missed by both the isolated reviewer and every test in this branch. Neither workflow forwarded its flags to the init CLI: plan-phase.md:71 INIT=$(gsd_run query init.plan-phase "$PHASE" $GRAN_PARAM) execute-phase.md:84 INIT=$(gsd_run query init.execute-phase "${PHASE_ARG}") So every flag: atom was permanently false in production and its section permanently excluded. For plan-phase that made the PRD express path UNREACHABLE — a regression, since it was an unconditional read before. For execute-phase this is PRE-EXISTING: #2932 shipped `flag:--wave` gating that has never once been true, so `--wave` silently dropped its own wave-filtering guidance. Fixed here under the no-defer rule. Why every test missed it: they drive the init CLI directly with flags, which works. Production goes through the workflow's bash line, which did not pass them — the exact "assert against the shape production uses" trap this branch's own test matrix warns about. - parse and forward --prd/--ingest/--research-phase/--reviews/--chunked (plan-phase) and --wave (execute-phase), using the anchored regex idiom the neighbouring GRAN_PARAM line already uses - add a regression guard DERIVED FROM THE MANIFEST: for every flag:--X section, the owning workflow's init line must forward --X. It fails against the pre-fix files and covers any future atom, rather than spot-checking today's six. Verified through the workflow shape, not the CLI shape: `3 --prd spec.md` now yields ["prd-express-gate"] (was []), `2 --wave 2` yields ["partial-wave"] (was []). Refs #2993 * test(#2993): acknowledge the execute-phase ripple and regenerate install-tree fixtures Remote matrix was red with 46 unique failures, identical on both lanes. Both causes are mechanical consequences of changing shipped workflow content, and neither is visible to any local gate. - emitted-attribution: execute-phase.md grew 163 bytes from the WAVE_PARAM forwarding fix and was unacknowledged, while the ack fragment named plan-phase.md, which SHRANK and therefore needed no ack at all — a stale entry is itself a failure. The reason now names the real ripple. The entry had to merge into the existing 2930 fragment: the ack linter does unconditional cross-fragment duplicate-key detection with no spent/live exception, so a second fragment declaring execute-phase.md collides even when the first is already merged and inert. Resolved per the linter's own guidance and that file's precedent of appending successive ripple reasons to one entry. - golden-install-tree: tests/fixtures/install-tree/*.json are committed and deliberately excluded from the ADR-2719 attribution cutover, so they must be regenerated when shipped tree content changes. Regenerated after build:lib per the ordering landmine. 19 runtimes each gained exactly the six new plan-phase step files; zero paths removed, which is the absolute failure shape those fixtures exist to catch. Refs #2993 * fix(#2993): restore the launcher preamble in an extracted step and follow moved content in its drift guards Second red run: 26 unique failures, identical on both lanes, in two classes. RUNTIME BUG (runtime-launcher-parity, 7 failures) — chunked-planning-mode.md calls gsd_run but carried no canonical launcher preamble, which is what DEFINES gsd_run(). On any non-Claude runtime that step would fail outright. The preamble is now copied verbatim from the canonical source of truth, gsd-core/workflows/_runtime-launcher.snippet.sh, and the fence dedented to column 0 to match the prd-express-path.md sibling (a list-continuation indent breaks the byte-equal preamble match). prd-express-path.md already had a correct one. This is the same defect #2932 hit when it extracted steps; the parity test caught a real bug, not a stale assertion. DRIFT GUARDS (plan-phase-drift-guard, issue-2762-plan-reviews-chunked, skill-frontmatter-contract) — these assert plan-phase.md contains content this branch moved into step files. Retargeted at where the content now lives, with the asserted property unchanged; the ALL-RUNTIMES label COUNT test now reads host + every step file so the count is preserved across the split rather than reduced. Each retargeted guard was verified to still fail when its step file is stripped, so none was weakened into vacuity. No emitted-drift ack was needed: currentSizes() enumerates gsd-core/workflows/*.md non-recursively, so files under plan-phase/steps/ are never in the size ratchet's scope.

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.
