* test(4032): add failing installed-agent grants contract Cover global and project agent_tools precedence at the real Claude installer seam before adding implementation. * feat(4032): apply configured agent tool grants during staging Resolve selector-level global and project config once per staging call, then append validated grants before runtime conversion. * test(4032): cover host grant and quoted MCP contracts Exercise installed host artifacts and prove ZCode must treat quoted MCP scalars like plain MCP grants. * feat(4032): apply configured agent tool grants across runtimes Move augmentation and scalar identity into the converter seam so every staged artifact preserves host policy. * fix(4032): register agent tool grants in configuration Accept documented agent_tools config without unknown-key warnings.\n\nKeep installer fixtures on the shared temporary-directory helper. * fix(4032): translate configured MCP grants for Kilo Reuse the converter-owned scalar decoder so quoted canonical grants reach Kilo's native permission keys without altering other host policies. * fix(4032): decode YAML-escaped tool grants * fix(4032): emit valid inline agent tool grants * fix(4032): reject invalid trailing-colon grants * test(#4032): cover cross-review remediation gaps * fix(#4032): close cross-runtime grant gaps * test(#4032): expose Kimi global project context * fix(#4032): preserve Kimi project config context * chore(#4032): add release note * test(#4032): expose fork review regressions * fix(#4032): address fork review findings * test(#4032): make byte-stability assertion portable Compare repeat installs at one root so platform-specific path rendering cannot masquerade as an agent_tools behavior change. * chore(#4032): bind changeset to upstream PR 4238 * fix(#4032): address trek-e review findings (2,3,4,5,6,7,8) Fixes fail-closed decode-failure handling in ZCode's mcp__ stripper, a comment-only `tools:` header mis-parse that silently dropped configured grants, and a naive comma-split that could tear a quoted scalar containing a literal comma. Documents Kilo's inherent `{server}_{tool}` MCP-permission-key collision (external, fixed format — not ours to widen) and locks the existing first-seen-wins resolution in with a regression test. Opts kimi/kimi-code out of the ADR-1235 pre-converter path-rewrite step: routing Kimi through that pipeline (needed so project-scoped agent_tools selectors reach it) was short-circuiting Kimi's own neutralizeKimiAgentPrompt, which expects the original ~/.claude/gsd-core text rather than a pre-rewritten Kimi path. Extends the fast-check token pool and per-runtime install coverage with the missing comment/comma/broad-runtime cases the prior review flagged as untested. * docs(#4032): add CONTEXT.md glossary entries for agent_tools resolver + pre-converter step Documents readGsdEffectiveAgentTools (Install Model Override Resolver Module) and the appendAgentTools pre-converter pipeline step (Runtime Artifact Conversion Module), per contributor-standards.md's new-seam glossary requirement (finding 1). * fix(#4032): address agy adversarial review findings An agy (gemini-3.8-flash-high) adversarial pass over the prior review-fix commit found the fixes for findings 3, 4, 6 and 8 had unfixed sibling gaps, plus a genuine new regression and two CONTEXT.md inaccuracies: - ZCode's comment-only `tools: # note` header matched the inline-value branch instead of falling through to the block-list scan, so a following mcp__* item leaked through unstripped — the exact defect finding 4 fixed in appendAgentTools, unfixed in this sibling function. - Reverted capabilities/kimi-code/capability.json's noPathRewrite: true. kimi-code uses the standard 'agents' kind with converter: null (not kimi-agents — confirmed by reading the descriptor, not its prose description), so it never went through the pipeline change finding 5 fixed, and disabling its path rewrite broke every ~/.claude/ embed in its shipped agents instead. - decodeToolScalar never stripped a trailing ` # comment` from a bare (unquoted) scalar, so a comment after a block-list item, or after an appended grant on an inline line, became part of the "tool name" — fixed at the source (one call site fixes every consumer). - appendAgentTools's comment-index scan wasn't quote-aware, so a `#` inside a quoted scalar (`"mcp__server #1"`) was mistaken for a comment start and corrupted the quote. - parseFrontmatterTools (Kimi/Qwen's tool-list reader, downstream of appendAgentTools's own output) had the same naive comma-split and comment-only-header gaps as findings 4 and 6, unpatched. - The all-runtime smoke test's presence assertion was built on a guessed omit-list; empirically only 7 of 17 runtimes keep an arbitrary mcp__ grant recognizable, replaced with a verified allowlist. - CONTEXT.md claimed a `project:<agent>` selector prefix that does not exist (project override is a same-key merge across two config files) and mislabeled stageAgentsForRuntimeWithConverter's module. * fix(#4032): address full-PR review (Opus critical/ponytail + agy) A whole-PR pass (critical-code-reviewer + ponytail-review on Opus, plus a second agy full-source adversarial pass) surfaced defects the earlier finding-scoped passes couldn't reach: - appendAgentTools corrupted a `tools:` line whose ENTIRE value is a leading quoted scalar (`tools: "Read"` -> `tools: "Read", Write`, invalid YAML) — there is no safe line-surgical rewrite here, so it now refuses to touch that shape instead of emitting broken frontmatter. - decodeToolScalar's malformed-trailing-quote check ran BEFORE comment stripping, so a bare tool name with a quote inside its own trailing comment (`Bash # note: "internal"`) was wrongly rejected. Reordered. - findUnquotedCommentIndex (added in the prior remediation commit) was built on a wrong model of YAML: a `#` after whitespace starts a real comment in a plain scalar regardless of nearby quote characters — verified against the actual parser. The one case that DOES need protection (a leading quoted scalar) is now refused outright above, so the quote-tracking scan was dead weight solving a problem that no longer reaches it. Removed; reverted to the plain `[ \t]#` scan. - Kilo has a SEPARATE agent-frontmatter parser (convertClaudeToKiloFrontmatter, distinct from the buildKiloAgentPermissionBlock fixed earlier) with the same comment-only-header and naive-comma-split gaps as findings 4 and 6 — unfixed in both its src/ and bin/install.js copies. Fixed in both, exporting splitToolScalars for bin/install.js to reuse rather than reimplementing it. - Pipeline docstring in stageAgentsForRuntimeWithConverter still listed 5 steps, omitting appendAgentTools (now step 3 of 6). - docs/CONFIGURATION.md didn't state that a --global install still discovers agent_tools from the cwd's .planning/config.json (confirmed intentional and already covered by a dedicated test, not a bug). - Removed install-engine.cts's deps.cwd injection seam: zero callers or tests ever populated it. Two claims from this round were verified and rejected, not fixed: prototype pollution via a `__proto__` selector key (empirically confirmed `Object.prototype` is never touched — only reassigns the resolver's own local object's prototype, with no observable effect), and a `*` grant value crashing YAML parsing as an alias reference (empirically confirmed it parses as plain scalar text, no crash). A pre-existing, unrelated defect (extractFrontmatterField returns null for block-list `tools:` on Copilot/Antigravity/Cursor/Codex/Qwen, affecting two shipped agents today) was filed as a follow-up rather than fixed here — it predates #4032 and isn't caused or worsened by this PR. * fix(#4032): update stale slug-derivation-drift-guard fixture line normalizeKimiSkillName's real closing brace moved from line 616 to 635 as a side effect of this PR's edits to runtime-artifact-conversion.cts; the MAJOR-1 fixture's hardcoded realEndLine had gone stale. * fix(#4032): address CodeRabbit findings on projectDir threading and flow-sequence tools bin/install.js's installAgentsKindStandalone call site omitted the projectDir argument the function already supports, so a global install through this legacy branch silently fell back to the runtime config dir instead of process.cwd() when resolving project-scoped agent_tools grants — inconsistent with the sibling installOpencodeFamilyArtifacts call site, which already threads it correctly. appendAgentTools' leading-quoted-scalar bailout did not cover a YAML flow sequence (`tools: [Bash, Read]`): splitToolScalars tore it apart on the in-sequence commas and appended past its closing bracket, producing invalid frontmatter. Extended the bailout regex to also refuse a value starting with `[`, matching the same "whole node, nothing may follow" reasoning already applied to quoted scalars. --------- Co-authored-by: CI Rebase Check <ci@gsd-redux> Co-authored-by: Test <test@test.com> 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.
