* feat(#323): fish-shell support in post-install PATH suggestion Two additive changes to the post-install PATH-suggestion seam, both scoped to existing functions. A. Projection: add a fish entry to the persist-mode shell-action list in projectPathActionProjection() (src/shell-command-projection.cts). fish has no `export`/`$PATH`-list syntax, so the existing zsh/bash `export PATH=...` commands are inert when pasted. The new entry emits the fish-native `fish_add_path '<dir>'` (fish 3.2+, persists via the universal-variable store, de-duplicating). The directory is single-quoted with the same POSIX literal escaping as the zsh/bash siblings; verified round-tripping through real fish 3.7.0 for paths containing quotes, spaces, `$`, `*`, backticks and unicode. B. Detection: add homePathCoveredByFishConfig() in bin/install.js, called from maybeSuggestPathExport() alongside homePathCoveredByRc(). fish does not use sh-style `export PATH=` rc files, so a fish user whose fish_user_paths already covers the global bin would otherwise get a false-positive "not on your PATH" warning on every install. Two side-effect-free detection routes (no fish subprocess): 1. The universal-variable store (~/.config/fish/fish_variables). fish serializes this with `full_escape`: every byte outside [A-Za-z0-9/_] becomes `\xHH` (space -> \x20, `-` -> \x2d, `.` -> \x2e, `$` -> \x24, unicode -> \uXXXX) and list elements are joined by the literal 4-char token `\x1e` (NOT a raw 0x1e byte). The detector splits on `\x1e`, decodes the escapes, then compares each as an absolute literal — a decoded `$` is part of the directory name, not an unexpanded variable. Verified against real fish 3.7.0 output. 2. config.fish (`fish_add_path`, `set -gx PATH`, `set -Ux fish_user_paths`) — plain shell tokens: HOME forms ($HOME/${HOME}/~) are expanded and a token still holding `$` (e.g. `$PATH`, `$fish_user_paths`) is skipped. Honours $XDG_CONFIG_HOME and always also checks ~/.config/fish. No behaviour change for bash/zsh/PowerShell/cmd/Git-Bash users: their entries and command strings are unchanged; the fish entry is additive and the fish detector only narrows the set of cases that warn. Tests: update the projection length assertion (2 -> 3) and fish escaping in bug-3441; add fish detection + suppression cases in install-path-detection (uvar store with real fish escaping, dot/hyphen/space/$-literal decode regressions, config.fish routes, commented-out, relative-segment guard, unreadable-file fault injection, suppression and emission via maybeSuggestPathExport).

Drop the `# fish — persists via …` comment and the internal-mechanism clause naming fish_variables/config.fish; leave one command + the exec-fish directive. - tests (minor): extract decodeFishUniversalValue to a pure, exported module function and add fast-check round-trip properties (decode(fishEscape(p)) === p over arbitrary unicode, abs-path variant, totality). Consolidated into install-path-detection.test.cjs to respect the install test-file-count ratchet. - tests (follow-up): port #721's win32 negative-projection test (no fish action on win32; persist projection is PowerShell/cmd.exe/Git Bash).

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, Gemini 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, Gemini 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, Gemini 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 your first project:
/gsd-new-project

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.
