* refactor(#1170): remove hand-maintained INVENTORY count scalars The `(N shipped)` heading counts in docs/INVENTORY.md were absolute scalars that collided silently on merge: two branches each bumping the same integer to N+1 produced a clean git merge whose value the merged filesystem (N+2) contradicted, hard-failing inventory-counts.test.cjs on the CI merge commit across all platforms (DEFECT.INVENTORY-MERGE-UNDERCOUNT). - Strip the six `(N shipped)` heading counts + the two prose footnote counts; repoint the intro to INVENTORY-MANIFEST.json as the registry. - Drop the decorative `generated` date from the manifest + its strip-before-compare branch in gen-inventory-manifest.cjs (it conflicted on cross-day merges and is read by nothing). - Delete inventory-counts.test.cjs (scalar-vs-disk gate, the collision source); its drift protection is subsumed by the merge-safe set-membership test inventory-manifest-sync.test.cjs, which stays as the sole gate. - Add inventory-headings-countfree.test.cjs guard (fails if a count is re-added to a heading). - Fix already-broken count-bearing cross-doc anchors to stable count-free slugs in ARCHITECTURE.md + multi-agent-orchestration.md. - Retire the now-impossible DEFECT.INVENTORY-MERGE-UNDERCOUNT + obsolete RULESET.DOC-CONSISTENCY in CONTEXT.md; de-count DEFECT.INVENTORY-DRIFT; correct stale MANIFEST-CANONICAL-KEY (all six families canonical).

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 - 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
- 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
- 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
- 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
