`gsd-tools config-set <key> null` — the "Clear" action documented in
settings-integrations.md / settings-advanced.md — previously fell through the
value parser as the literal STRING "null" and persisted it. Consequences:
"cleared" keys stayed set (config-get returned truthy "null"), and for secret
keys (brave_search/firecrawl/exa_search) a masked success line hid a truthy
4-char value on disk that integrations could pass along as a real credential.
There was also no unset/delete verb at all.
Fix: parse a bare `null` to JS null and short-circuit to a real UNSET that
DELETES the key from config.json — the semantic the docs already describe
("Remove the stored key" / "remove the key by setting it to null"). Deleting
(not persisting JSON null) is the correct clear: a persisted null is still a
present value consumers must special-case.
- src/config.cts:
- parse block: `else if (val === 'null') parsedValue = null;`
- cmdConfigSet: when parsedValue === null, short-circuit BEFORE the typed
per-key validator gauntlet (so clearing an enum/boolean/number key removes
it rather than being rejected) and before the project_code special-case;
mask the previous value for secret keys in the output.
- new `unsetConfigValue()` + `_unsetNestedValue()` mirroring setConfigValue/
_setNestedValue: same prototype-pollution guard, but never creates missing
intermediates and never prunes empty parents; returns { previousValue,
existed }. Unsetting a never-set key is an idempotent no-op success.
- tests/config.test.cjs: new suite covering non-secret routing key, secret key,
typed-enum-key bypass (context), idempotent unset, literal-"null"-on-disk
guard, the unset-path prototype-pollution guard (alert #26 parity), and a
4-segment deep-nested unset.
- tests/review-model-config.test.cjs: update the stale round-trip test that
codified the bug (asserted config-set null → config-get returns "null") to the
fixed contract — the model key is removed; the review workflow's
`[ -n "$VAR" ] && [ "$VAR" != "null" ]` guard handles the empty read as
"no override → reviewer default", same as the old "null" sentinel.
The 4 documented "Clear" flows (settings-integrations.md, settings-advanced.md)
were verified — their prose already describes removal, so the fix makes them
accurate rather than aspirational; no doc wording change required.

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.
