`gsd-tools effort sync` crashed in every installed runtime (e.g. ~/.claude/gsd-core/) with `Cannot find module '../../../bin/install.js'`: cmdEffortSync (src/commands.cts) required the package-root bin/install.js for its install-time effort resolvers, but the installer only copies the gsd-core/ subtree into a runtime home — bin/install.js is never present there. So `effort` config changes silently never reached installed agents without a full reinstall (exactly the gap #488 was meant to close). 4th instance of the recurring "runtime code under gsd-core/ requires a file outside the shipped subtree via ../../../" anti-pattern (#1223/#1920/#1383 were the prior three, all already mitigated). Fix (ADR-457 direction — extract, single source): move readGsdEffectiveEffortConfig + resolveInstallTimeEffort (with their _getGsdEffortCatalog + _readGsdConfigFile helpers) out of the hand-authored bin/install.js into a new src/install-effort-resolver.cts that compiles into the shipped gsd-core/bin/lib/install-effort-resolver.cjs. commands.cts now requires it as a sibling (`./install-effort-resolver.cjs`) — always present in the installed tree — instead of `../../../bin/install.js`. bin/install.js imports the same four symbols back from the new module (it still calls them + re-exports them), so there is one source of truth and no duplication/drift. The lazy manifest read is repointed from the package-root layout (`.., gsd-core, bin, shared`) to the bin/lib layout (`.., shared`). Scope note: this is one of four instances of the anti-pattern; the other three are already shipped/guarded. A build-time guard rejecting new cross-boundary requires whose target isn't in the installer copy manifest (to prevent instance #5) is recommended on the issue but kept out of this fix. Tests: tests/effort-sync-installed-runtime.test.cjs does a real minimal install into a temp home (the golden-parity helper) and runs the issue's exact repro (`gsd-tools effort sync --config-dir <temp>`), asserting no MODULE_NOT_FOUND for bin/install.js. Fail-first verified: against pristine next the same test throws `Cannot find module '../../../bin/install.js'` at cmdEffortSync; post-fix it syncs cleanly. New module registered in .gitignore (ADR-457), eslint ignores, docs/INVENTORY.md + INVENTORY-MANIFEST.json. bin/install.js is not shipped and the new module is under bin/lib (excluded from golden parity), so no golden fixtures change.

GSD Core documentation
Documentation is organised into four quadrants: tutorials help you learn by doing, how-to guides solve specific tasks, reference states authoritative facts, and explanation explores concepts and design decisions.
Language versions: English · Português (pt-BR) · 日本語 · 简体中文
Tutorials
- Your first project — install to first shipped phase, one guaranteed path
- Onboarding an existing codebase — bring GSD Core to a brownfield repo
- Build your first capability — author a tiny declarative capability and watch it act in the loop
- Install your first capability — install a third-party capability end-to-end: consent, verify, check for updates, remove
How-to guides
- Install on your runtime — runtime-specific install steps for all 16 supported runtimes
- Install a minimal GSD and add skills later — install only the core skills, then grow the surface with profiles and
/gsd:surface - Attach a plugin-provided skill to a GSD agent — use the
global:plugin:skillentry form to load Claude Code plugin skills into agent prompts - Discuss a phase — capture implementation decisions before planning begins
- Resolve edge-coverage findings — turn the spec phase's surfaced domain-boundary edges into covered, dismissed, or backstopped spec decisions
- Resolve prohibition findings — turn the spec phase's surfaced must-NOT constraints into resolved, dismissed, or deferred spec decisions
- Plan a phase — run research, decompose work, and verify plan quality
- Execute a phase — run plans in parallel waves with fresh-context subagents
- Verify and ship — walk through completed work, diagnose failures, and create the PR
- Run phases autonomously — use autonomous mode for unattended phase execution
- Handle quick and fast tasks — use
/gsd-quickand/gsd-fastfor ad-hoc work outside the phase loop - Configure model profiles — switch between quality, balanced, and budget model tiers
- Set up cross-AI review — configure a second AI to review code produced by the primary agent
- Work in parallel with workstreams — run independent lines of work simultaneously using workstreams
- Isolate work with workspaces — use workspaces to sandbox experimental or risky changes
- Debug a failed execution — diagnose and recover from broken or incomplete phase execution
- Spike and sketch — use
/gsd-spikeand/gsd-sketchfor exploratory work before committing to a plan - Design a UI phase — use the UI phase loop for frontend and visual work
- Develop a Capability for GSD 1.5+ — add feature Capabilities, hook fragments, and registry entries
- Add or update a host's integration — set a host's documentation-sourced
runtime.hostIntegrationaxes (ADR-1239 Phase A), with theundocumentedsentinel rule - Turn a capability off (and keep it off) — disable a capability via the surface, or gate individual hooks off without removing the capability
- Drive GSD from a tracker issue — start a phase from a GitHub, Linear, or Jira issue
- Migrate from GSD 2 — upgrade an existing GSD 2 project to GSD Core
- Update GSD — re-run the installer to pick up the latest release
- Clean up get-shit-done-cc — remove leftover old-package artifacts that cause a spurious
⬆ /gsd:updateindicator after migrating to@opengsd/gsd-core - Fix the worktree base-mismatch (exit 42) error — resolve the branch-divergence condition that halts parallel phase execution
- Recover and troubleshoot — fix common problems, rebuild context, and uninstall

Explanation
- Context engineering — how context rot forms and how GSD Core prevents it
- The phase loop — design rationale for the Discuss → Plan → Execute → Verify → Ship cycle
- Multi-agent orchestration — how subagents are spawned, scoped, and coordinated
- Security model — trust boundaries, permissions, and safe automation
- The capability trust model — why third-party capabilities are gated by consent + integrity + reversibility, not a sandbox
- How overlay capabilities compose — why first-party always wins and how the loader resolves precedence, conflicts, and fail-closed gates
- Architecture — system architecture, agent model, and data flow
- Discuss modes — assumptions mode vs interview mode for
/gsd-discuss-phase - Context monitoring — context window monitoring hook architecture
- Issue-driven orchestration — recipe for driving GSD from a tracker issue using existing primitives
