* fix(#3206): define "explicit evidence" inline at verifier 5b; repair stale honest-verifier cites
Step 3 item 5b abstained on non-inferable (backstop) truths "unless
confirmed by explicit evidence" with the term undefined — its definition
lived only in the non-included gsd-core/references/honest-verifier.md,
behind a stale bare `references/` cite that 404s. Undefined, the term
falls back to presence + wiring, the exact false-pass the #1154
abstention protocol refuses.
- 5b: inline the compressed definition (a passing wired
held-out/property-based test or directly observed behavior; presence +
wiring never qualifies) and fix the cite. +84 B on the rewritten line;
file lands at 49,151 of the 49,152 LARGE cap.
- verifier-phase-gates.md (already <required_reading>): gains the
backstop-abstention reporting contract — AFK completion line
("complete with N unverified non-inferable checks", never silent,
never a halt) and reason-distinctness (insufficient_spec vs manual-UAT
human_needed). New content, no relocation of measured prose.
- 5c (line 204) and MVP-mode (line 644) bare cites repaired to
gsd-core/references/ (+9 B each).
- Drift acks per ADR-2719 §4; two entries merge-appended into existing
fragments (two ack sources may never name the same path).
- Changeset fragment with the sanctioned pr: 0 placeholder (post-create
backfill).
Sibling census at next@7976b1ca0: 7 bare-cite instances in 4 agent
files; the 3 in gsd-verifier.md are fixed here, gsd-executor.md:429,439
and gsd-doc-synthesizer.md:20,176 stay with the epic #1891 follow-up.
Refs #1891
* chore(#3206): set changeset fragment pr to 3435
* fix(#3206): drop stale emitted-drift-ack entries that trip the ADR-2719 ratchet
The round's ack bookkeeping explained ripples that were already
self-attributed, so `tests/emitted-attribution.test.cjs` failed
deterministically on the PR head with 5 stale acknowledgments.
`agents/gsd-verifier.md` and `gsd-core/references/verifier-phase-gates.md`
appear directly in `git diff --name-only`, so PROVENANCE_RULES attributes
their emitted deltas without an ack; `agents/gsd-verifier.agent.md`,
`agents/gsd-verifier.toml` and `agents/subagents/gsd-verifier.md` are
derived emissions of a changed source and are attributed the same way.
None of the five entries could ever be consumed, so all five were stale.
Removed: the whole `3206-verifier-explicit-evidence.json` fragment (all
four entries) and the `#3206 append` to `0000-legacy-migration.json`.
Deliberately KEPT: the `#3206 append` to
`1955-verifier-coincidental-reliance.json`. Its `gsd-verifier.md` entry is
consumed by the size-growth ratchet, not the hash pass — the agent grew
49049 -> 49151 bytes, and `diffEmitted` treats a base-identical ack as
spent and excludes it from `ackEntries`. Reverting that append as well
turns the stale-ack failure into `1 file(s) grew without an
acknowledgment` (verified both ways locally).
* fix(#3206): compress 5b and re-acknowledge growth after rebase onto next
The rebase onto next (159145435, PR #3558) invalidated two things at once:
- #3558 grew agents/gsd-verifier.md to 49,098 bytes, leaving 54 bytes of
LARGE-cap headroom where this PR's +102 no longer fits. Compressed the
5b rewrite to +34 net by dropping the trailing honest-verifier cite —
superseded by the now-inline definition; honest-verifier.md stays
cited at the adjacent 5c line. File lands at 49,150 (2 under the cap).
- #3558 deleted tests/emitted-drift-acks/1955-verifier-coincidental-
reliance.json, which carried this PR's growth acknowledgment, and its
own 3409 fragment now names gsd-verifier.md. Re-homed the #3206 growth
ack as an append to that entry (two ack sources may never name the
same path).
The changeset is updated to match: two bare references/ cites repaired
(5c honest-verifier.md, MVP-mode verify-mvp-mode.md), the third (5b's)
superseded by the inline definition rather than repaired.
Reversion controls: restoring the uncompressed 5b fails
agent-size-budget.test.cjs (LARGE hard cap); reverting the ack append
fails emitted-attribution.test.cjs (differential attribution over the
real tree, GSD_EMITTED_BASE=upstream/next). Both re-verified green at
this tree: 213/213 (size + attribution), 992/992 across the 14 suites
reading the touched files.

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
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.
