* enhance(execute): isolated-executor rejected/over-reaching run fails safe (#1292) When an isolated (worktree) executor run is rejected — the user declines to merge it, the orchestrator surfaces recovery for a blocked/halted plan, or the run over-reached the requested scope — the orchestrator must no longer default/propose recovery by editing the primary checkout (`main`). Absent an explicit guardrail, the LLM orchestrator could improvise "continue on main", inverting the isolation contract at the moment it matters most. Added an ISOLATED-RUN RECOVERY — FAIL SAFE policy: default to a safe halt that offers a fresh, narrowly-scoped worktree or inspect/discard; editing the primary checkout requires explicit, clearly-labeled confirmation and is never the default/proposed option. To respect the ADR-857 phase-6 host-loop size cap on execute-phase.md (it sits just under the pre-phase-6 baseline), the policy is delivered as an extracted reference fragment rather than inline: - New `execute-phase/steps/worktree-recovery-policy.md` holds the recovery policy (the existing FAIL-CLOSED rule #48 for base/HEAD mismatches + the #1292 fail-safe guardrail). No #48 behavior change — moved verbatim. - execute-phase.md references the fragment at the worktree-spawn recovery point, the step-5.5 merge decision, and the stalled-agent "switch to inline execution" menu (which for an isolated run now follows the fail-safe policy). Net effect: execute-phase.md shrinks below its cap. - quick.md carries the fail-safe guardrail inline at its post-return merge/discard decision (quick.md is not size-capped). Scoped to the recovery offer only — no automatic scope-overreach detection (explicitly out of scope per the issue) and no new config key. Adds content regression tests, a USER-GUIDE note, and a workflow size-baseline update.

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
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
- 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
