* chore(#2800): derive reviewer flag lists and gate reviewer lane docs across locales The reviewer lane roster was hand-enumerated across five documentation surfaces and three workflow files that had drifted apart: --kimi-code was missing from all four translated COMMANDS.md mirrors, --coderabbit from every workflow forwarding list, and --antigravity from FEATURES.md. Adds checkReviewerDocsParity, a second pure gate deliberately separate from checkReviewerLaneParity so a stale doc cannot make the runtime checker look red. Workflows now derive their flag lists from a new review-lane flags query instead of hand-enumerating them, which also retires the unanchored grep that matched --agy inside --antigravity. Documents the previously absent reviewer body and hostBehaviors field in the capability manifest reference. Closes #2800 Closes #2781 Closes #2272 * fix(#2800): key the docs parity table arm on first-cell position Review found the flag arm was file-scoped, so the forwarding row that lists every flag in its third cell satisfied it on its own. Deleting a lane's own reviewer-table row -- the #2781 regression this gate exists to prevent -- therefore passed undetected. Arm 4 keys on the FIRST table cell, which separates a lane row from the forwarding row structurally and in every locale. Regression test included. * fix(#2800): shape-filter the flags subcommand output All three consumers read review-lane flags through an unquoted command substitution so the output word-splits into loop items. Phase 2 admits third-party overlay lanes, so an overlay flag containing whitespace would inject a second loop item and one containing a glob would expand against the cwd. Emit only well-formed flags so neither reaches the shell. * fix(#2800): remove the regex length ceiling and count only prose mentions Review found two real defects in the docs parity gate. The never-throws contract was false: building a RegExp from a declared flag or section title throws SyntaxError past ~100k chars, and Phase 2 admits overlay lanes whose declared strings are untrusted in length. Every one of these matches is literal, so String.includes replaces the regex outright, which also deletes escapeLiteral and the llama.cpp escaping it existed for. Arm 1 was context-blind: a flag mentioned only inside a fenced example or a commented-out row counted as documented. Both are stripped before matching. Also advertises all 13 lane flags in the argument-hint and corrects a stale eleven-lane count in the slug grammar note. * test(#2800): repoint the convergence suite off deleted workflow text The derived flag loop deleted the literal per-flag grep lines four tests matched on. Two of those failed loudly. The behavioral and property tests failed SILENTLY instead: their end marker no longer resolved, so the parse block extracted empty and both passed vacuously, and the property test's gsd_run stub had a no-op default that hid it. All now share one extractor and execute the real deployed block through a gsd_run shim backed by the actual binary. The whitelist assertions become an anti-parity check: re-adding a hand-written flag list must fail. Also repairs two vacuous cases in the docs parity suite. The unreadable-doc test called its own mock rather than the reader, and the integration test bounded nothing, so a doc losing its marker would have been silently skipped and still passed green. * fix(#2800): run the derived flag loop after the launcher preamble The remote matrix caught a real runtime bug, not a test artifact. In autonomous.md and plan-review-convergence.md the launcher preamble that defines gsd_run lives in a separate, LATER bash fence than the derived loop. Each fence is its own shell, so gsd_run was undefined where the loop ran: the command substitution yielded nothing and zero reviewer flags would have been forwarded. Worse than the drift this epic fixes, and silent. The whole CONVERGENCE_ARGS construction moves as one unit, because the --max-cycles append sits between the loop and the preamble and would otherwise have run against an uninitialized variable and then been dropped by the relocated initializer. Also documents all 13 lane flags in help/modes/full.md, which the repo gates bidirectionally against each command's argument-hint. * test(#2800): repoint the two converge suites off deleted flag literals Both asserted workflow.includes('--codex') against the hand-enumerated list the derived loop removed. They now assert the derivation itself, keep --all and --text (convergence controls, still literal), and add an anti-parity guard so re-adding a hardcoded list fails. The lost pass-through proof is replaced with a real one: every flag the tests used to hardcode is asserted present in the actual roster emitted by the binary, which is the property the old assertion was protecting. * test(#2800): acknowledge the workflow byte growth from the derived flag loop * chore(#2800): backfill changeset pr number to 2882 * fix(#2800): strip HTML comments to a fixed point in the parity gate CodeQL js/incomplete-multi-character-sanitization (high) on PR #2882: the single-pass <!--...--> strip can leave a live <!-- behind, so a join-trick construction smuggles a commented-out row past the gate and it counts as documented. Not an injection risk here since nothing is rendered, but it is the exact false pass this helper exists to prevent. Strips to a fixed point, then treats any surviving opener as unterminated so the multi-line branch closes it on a later line. Terminates because every pass strictly shortens the string. * test(#2800): pin the comment-smuggling regression with a real reproducer The obvious fixture for this class does not reproduce it: <!--<!---->--> leaves a dangling --> rather than a live <!--, and is caught either way, so it would have passed with and without the fix. The join-trick construction (<!- + <!--DUMMY--> + -...-->), the <scr<script>ipt> shape, genuinely regresses on the single-pass strip and is what the test now uses. --------- Co-authored-by: Test <test@example.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.
