chore: initial backup of Claude Code configuration

Includes: CLAUDE.md, settings.json, agents, commands, rules, skills,
hooks, contexts, evals, get-shit-done, plugin configs (installed list
and marketplace sources). Excludes credentials, runtime caches,
telemetry, session data, and plugin binary cache.

+
+<objective>
+Debug issues using scientific method with subagent isolation.
+
+**Orchestrator role:** Gather symptoms, spawn gsd-debugger agent, handle checkpoints, spawn continuations.
+
+**Why subagent:** Investigation burns context fast (reading files, forming hypotheses, testing). Fresh 200k context per investigation. Main context stays lean for user interaction.
+</objective>
+
+<context>
+User's issue: $ARGUMENTS
+
+Check for active sessions:
+```bash
+ls .planning/debug/*.md 2>/dev/null | grep -v resolved | head -5
+```
+</context>
+
+<process>
+
+## 0. Initialize Context
+
+```bash
+INIT=$(node "C:/Users/yaoji/.claude/get-shit-done/bin/gsd-tools.cjs" state load)
+if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi
+```
+
+Extract `commit_docs` from init JSON. Resolve debugger model:
+```bash
+debugger_model=$(node "C:/Users/yaoji/.claude/get-shit-done/bin/gsd-tools.cjs" resolve-model gsd-debugger --raw)
+```
+
+## 1. Check Active Sessions
+
+If active sessions exist AND no $ARGUMENTS:
+- List sessions with status, hypothesis, next action
+- User picks number to resume OR describes new issue
+
+If $ARGUMENTS provided OR user describes new issue:
+- Continue to symptom gathering
+
+## 2. Gather Symptoms (if new issue)
+
+Use AskUserQuestion for each:
+
+1. **Expected behavior** - What should happen?
+2. **Actual behavior** - What happens instead?
+3. **Error messages** - Any errors? (paste or describe)
+4. **Timeline** - When did this start? Ever worked?
+5. **Reproduction** - How do you trigger it?
+
+After all gathered, confirm ready to investigate.
+
+## 3. Spawn gsd-debugger Agent
+
+Fill prompt and spawn:
+
+```markdown
+<objective>
+Investigate issue: {slug}
+
+**Summary:** {trigger}
+</objective>
+
+<symptoms>
+expected: {expected}
+actual: {actual}
+errors: {errors}
+reproduction: {reproduction}
+timeline: {timeline}
+</symptoms>
+
+<mode>
+symptoms_prefilled: true
+goal: find_and_fix
+</mode>
+
+<debug_file>
+Create: .planning/debug/{slug}.md
+</debug_file>
+```
+
+```
+Task(
+  prompt=filled_prompt,
+  subagent_type="gsd-debugger",
+  model="{debugger_model}",
+  description="Debug {slug}"
+)
+```
+
+## 4. Handle Agent Return
+
+**If `## ROOT CAUSE FOUND`:**
+- Display root cause and evidence summary
+- Offer options:
+  - "Fix now" - spawn fix subagent
+  - "Plan fix" - suggest /gsd:plan-phase --gaps
+  - "Manual fix" - done
+
+**If `## CHECKPOINT REACHED`:**
+- Present checkpoint details to user
+- Get user response
+- If checkpoint type is `human-verify`:
+  - If user confirms fixed: continue so agent can finalize/resolve/archive
+  - If user reports issues: continue so agent returns to investigation/fixing
+- Spawn continuation agent (see step 5)
+
+**If `## INVESTIGATION INCONCLUSIVE`:**
+- Show what was checked and eliminated
+- Offer options:
+  - "Continue investigating" - spawn new agent with additional context
+  - "Manual investigation" - done
+  - "Add more context" - gather more symptoms, spawn again
+
+## 5. Spawn Continuation Agent (After Checkpoint)
+
+When user responds to checkpoint, spawn fresh agent:
+
+```markdown
+<objective>
+Continue debugging {slug}. Evidence is in the debug file.
+</objective>
+
+<prior_state>
+<files_to_read>
+- .planning/debug/{slug}.md (Debug session state)
+</files_to_read>
+</prior_state>
+
+<checkpoint_response>
+**Type:** {checkpoint_type}
+**Response:** {user_response}
+</checkpoint_response>
+
+<mode>
+goal: find_and_fix
+</mode>
+```
+
+```
+Task(
+  prompt=continuation_prompt,
+  subagent_type="gsd-debugger",
+  model="{debugger_model}",
+  description="Continue debug {slug}"
+)
+```
+
+</process>
+
+<success_criteria>
+- [ ] Active sessions checked
+- [ ] Symptoms gathered (if new)
+- [ ] gsd-debugger spawned with context
+- [ ] Checkpoints handled correctly
+- [ ] Root cause confirmed before fixing
+</success_criteria>
