* feat(#4221): gsd-secret-read-guard PreToolUse hook + registration Add hooks/gsd-secret-read-guard.js, a blocking PreToolUse guard on Read|Grep|Bash that denies reads of .env, .env.<suffix> and .secrets (the .env.example/.sample/.template/.dist templates stay readable). Read checks file_path; Grep checks an explicit path and judges the glob per brace alternative; Bash runs a two-pass token scan (quotes, comments, redirects with fd digits, separators, $( )/backtick/<( ) recursion, heredoc bodies never scanned as commands, nested bash -c/eval rescans, git <ref>:<path> shapes) with a closed non-reading exemption set for existence checks. Fail-open crash policy; 1 MiB commands are denied as command-too-large; more than 64 glob alternatives as glob-too-complex. Why: Claude Code 2.1.259 makes every `cd DIR && grep …` compound prompt for approval whenever any Read() deny rule exists, even in auto mode. A hook denial is not a permission rule and never arms that check. The installer-written deny rules are retired in the follow-up commit. Registration: hooks.json (Read|Grep|Bash, timeout 5), build-hooks HOOKS_TO_COPY, managed-hooks-registry, runtime-hooks-surface (blocking guard with BLOCKING_GUARD_TIMEOUT_S; Kimi ReadFile|Grep|Shell), shell-command-projection managed sets, installer-migration-report, OpenCode/Kilo plugin (grep tool mapping, include -> glob, dispatch), docs tables in five locales, ADR-766 always-on list, regen:derived fixtures, and a new table-driven unit suite. * test(#4221): pin the secret-read guard in existing hook gates Register gsd-secret-read-guard.js in every existing hook gate: the hooks-crash-policy table (deny row; 6 -> 7 deny cases), plugin-manifest REQUIRED_HOOKS and its Read|Grep|Bash group, docs-hooks-table-parity EXPECTED_SURFACE_HOOKS, install.test MANAGED_JS_HOOKS, install-minimal- hooks JS_HOOKS/BLOCKING_GUARDS, portable-node-runner GUARD_HOOKS, kilo-upgrades PLUGIN_GUARD_HOOKS, the Kimi normalization-parity and typed-payload floors, the OpenCode adapter (grep mapping, include -> glob, three dispatch tests) and a Kimi TOML matcher assertion. * fix(#4221): retire installer Read() deny rules (legacy filter) Rename GSD_CLAUDE_DENY_PERMISSIONS to GSD_CLAUDE_LEGACY_DENY_PERMISSIONS and stop adding the three Read(.env) / Read(.env.*) / Read(.secrets) strings. mergeClaudePermissions now only filters them out of an existing permissions.deny: an absent deny key stays absent, a malformed one is still repaired to [], and an array emptied by the filter is deleted so no `"deny": []` residue is left. Uninstall filters the same legacy list and, symmetric with the Antigravity branch, drops an emptied allow or deny key and an emptied permissions object. Unlike the #2278 allow-side migration there is no surviving current deny list, so the constant is renamed rather than mirrored. Removal is byte-exact: a hand-written identical rule is indistinguishable from the installer's and is removed too (the manifest never recorded permission strings). USER-GUIDE and CONTEXT.md updated. * test(#4221): flip install-regressions deny-rule assertions to the retired shape The fresh-merge, non-destructive merge, idempotency, end-to-end install, reinstall and uninstall assertions now expect no Read(.env*) deny rules and no permissions.deny key on a fresh install; the deny:null repair case is kept. A new describe block covers the legacy filter: retired strings removed with a user entry kept, partial sets, near-miss strings untouched, idempotency, GSD-only deny array deleted, a pre-existing empty deny preserved, and uninstall symmetry for allow/deny/permissions. * chore(#4221): add changeset fragment for PR #4236 * fix(#4221): case-fold names; scan shell stdin and xargs pipes Review round 1 (trek-e): - Blocker: secret-name matching is now case-insensitive in the Read, Grep (path and glob) and Bash paths, so `.ENV` / `.Secrets` on a case-insensitive filesystem are recognized as the same secret file. - Major: a shell interpreter's script is now scanned wherever it comes from. The tokenizer keeps heredoc bodies as per-segment tokens and records separator operators; pass 2 groups by segment id and resolves bash/sh/zsh/dash/ksh/su invocation mode: `-c` (including combined `-lc`) scans the script operand, a file operand is checked as a file (a `<( )` operand's echo/printf output is reconstructed), otherwise stdin is the script and heredocs, here-strings and a piped echo/printf source are scanned. `eval` joins all its operands; `source`/`.` handle process substitution. Data heredocs (`cat <<EOF`, the commit-message shape) stay unscanned. - Major: `… | xargs <cmd>` checks the upstream segment's operands as file names when the sub-command reads (`echo .env | xargs cat`, `find . -name .env | xargs cat`); `-a`/`--arg-file` suppresses the inference; a shell sub-command's `-c` script is scanned. Header, USER-GUIDE bullet and changeset updated; documented gaps now include piped scripts from non-echo sources and `exec`/`timeout` wrappers. 60 new suite cases pin the block and allow shapes. --------- Co-authored-by: Tom Boucher <trekkie@nomorestars.com>
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.
