* fix(#2460): pi before_provider_request fail-opens without explicit override pi/gsd.cjs's buildBeforeProviderRequestHandler unconditionally rewrote payload.model to the built-in pi/sonnet tier default (claude-sonnet-5) via resolveTierEntry's catalog fallback. For any pi user on a non-Anthropic provider (kimi-coding, zai, openrouter, openai-codex, minimax, ...), this silently broke every request: pi's chosen model was replaced with one the active provider did not know. The fix inspects model_profile_overrides.pi[tier] explicitly BEFORE calling resolveTierEntry (which falls back to the built-in catalog and would mask the 'user did not opt in' signal). When the user has not set an override (or set it to null), the handler returns undefined — fail-open — and pi's chosen model flows through untouched. Only an explicit opt-in via model_profile_overrides.pi[tier] steers. Tests: - the ACTUALLY-REGISTERED handler fail-opens when no override configured (was: 'steers to default-tier model-catalog pi id' — encoded the bug). - new test reproducing the reporter's exact repro (model: 'k3' → undefined). - override path: explicit model_profile_overrides.pi.sonnet config steers to the user-configured model id. - defensive: explicit null override also fail-opens. Per the reporter's suggested fix #1 of #2460. * test(#2460): regen pi golden parity + install tree fixtures pi/gsd.cjs changed → pi install hash changed → regenerate the parity + install-tree fixtures via UPDATE_GOLDEN=1 + UPDATE_INSTALL_TREE=1. * fix(#2460): treat empty-string override as fail-open (M1 review) Per code-review M1 + security M1: an explicit empty-string override (`{ pi: { sonnet: "" } }`) silently bypassed the fail-open guard because the check was `=== undefined || === null` only. resolveTierEntry's falsy `if (userRaw)` then fell back to the built-in catalog and rewrote payload.model to claude-sonnet-5 — re-introducing the exact bug this PR fixes, via a degenerate config shape. Fix: widen the guard to also reject `''`. The test now exercises both null and '' in a loop, asserting fail-open for both. * fix(#2460): clear hono/@hono/node-server moderate advisories via npm override GHSA-v422-hmwv-36x6-class advisories (3 moderate) appeared during this PR's session: - @hono/node-server <2.0.5 (path traversal on Windows via encoded paths) - hono 4.3.3 - 4.12.26 (API Gateway v1 adapter drops distinct repeated request header values) - both transitively via @anthropic-ai/claude-agent-sdk -> @modelcontextprotocol /sdk@1.29.0 The npm audit fix re-resolved hono to 4.12.31 (within the existing ^4.11.4 range declared by MCP SDK), clearing the hono advisory without an override. The @hono/node-server advisory cannot be re-resolved the same way: MCP SDK pins @hono/node-server@^1.19.9, and the fix requires 2.0.5+. There is no MCP SDK release that allows @hono/node-server@2.x (latest 1.29.0 is the most recent), and bumping @anthropic-ai/claude-agent-sdk to 0.3.x does not help (its peerDependency is still @modelcontextprotocol/sdk@^1.29.0). The override (sibling to the existing 'qs' and 'body-parser' entries) is therefore the only available tool — distinct from the body-parser case in re-resolution. Verified: npm audit --omit=dev reports 0/0/0/0 advisories. Also: regenerated the pi golden-install-parity fixture (the pi/gsd.cjs change in this PR altered the pi install hash). * docs(changeset): add Fixed fragment for #2460 PR The two-otters-jog.md changeset was created earlier but lost during the cherry-pick detour to fix #2454 PR 1's npm advisory cascade. Recreating here with PR number 2499 backfilled (no placeholder cycle needed).
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.
