release: v3.5.4

The stale detection was checking lastUpdate timestamps BEFORE
consulting session.status(), causing tasks to be unfairly killed
after 3 minutes even when the session was actively running
(e.g., during long tool executions or extended thinking).

Changes:
- Reorder pollRunningTasks to fetch session.status() before stale check
- Skip stale-kill entirely when session status is 'running'
- Port no-lastUpdate handling from task-poller.ts into manager.ts
  (previously manager silently skipped tasks without lastUpdate)
- Add sessionStatuses parameter to checkAndInterruptStaleTasks
- Add 7 new test cases covering session-status-aware stale detection

-## STEP 5: VERIFY GITHUB RELEASE
+## STEP 5: VERIFY RELEASE & PREVIEW AUTO-GENERATED CONTENT
+
+Two goals: confirm the release exists, then show the user what the workflow already generated.
 
-Get the new version and verify release exists:
 ```bash
-# Get new version from package.json (workflow updates it)
+# Pull latest (workflow committed version bump)
 git pull --rebase
 NEW_VERSION=$(node -p "require('./package.json').version")
-gh release view "v${NEW_VERSION}"

-
-## STEP 6: DRAFT ENHANCED RELEASE NOTES
-
-Analyze commits since the previous version and draft release notes following project conventions:
-
-### For PATCH releases:
-Keep simple format - just list commits:
-```markdown
-- {hash} {conventional commit message}
-- ...
-```
-
-### For MINOR releases:
-Use feature-focused format:
-```markdown
-## New Features
-
-### Feature Name
-- Description of what it does
-- Why it matters
-
-## Bug Fixes
-- fix(scope): description
-
-## Improvements
-- refactor(scope): description
-```
-
-### For MAJOR releases:
-Full changelog format:
-```markdown
-# v{version}
-
-Brief description of the release.
-
-## What's New Since v{previous}
-
-### Breaking Changes
-- Description of breaking change
-
-### Features
-- **Feature Name**: Description
-
-### Bug Fixes
-- Description
-
-### Documentation
-- Description
-
-## Migration Guide (if applicable)
-...
-```
-
-**CRITICAL: The enhanced notes must ADD to existing workflow-generated notes, not replace them.**
-
----
-
-## STEP 7: UPDATE GITHUB RELEASE
-
-**ZERO CONTENT LOSS POLICY:**
-- First, fetch the existing release body with `gh release view`
-- Your enhanced notes must be PREPENDED to the existing content
-- **NOT A SINGLE CHARACTER of existing content may be removed or modified**
-- The final release body = `{your_enhanced_notes}\n\n---\n\n{existing_body_exactly_as_is}`
+**After verifying, generate a local preview of the auto-generated content:**
 
 ```bash
-# Get existing body
-EXISTING_BODY=$(gh release view "v${NEW_VERSION}" --json body --jq '.body')
+bun run script/generate-changelog.ts
+```
 
-# Write enhanced notes to temp file (prepend to existing)
-cat > /tmp/release-notes-v${NEW_VERSION}.md << 'EOF'
-{your_enhanced_notes}
+<agent-instruction>
+After running the preview, present the output to the user and say:
+
+> **The following content is ALREADY included in the release automatically:**
+> - Commit changelog (grouped by feat/fix/refactor)
+> - Contributor thank-you messages (for non-team contributors)
+>
+> You do NOT need to write any of this. It's handled.
+>
+> **For a patch release**, this is usually sufficient on its own. However, if there are notable bug fixes or changes worth highlighting, an enhanced summary can be added.
+> **For a minor/major release**, an enhanced summary is **required** — I'll draft one in the next step.
+
+Wait for the user to acknowledge before proceeding.
+</agent-instruction>
 
 ---
 
-EOF
+## STEP 6: DRAFT ENHANCED RELEASE SUMMARY
 
-# Append existing body EXACTLY as-is (zero modifications)
-echo "$EXISTING_BODY" >> /tmp/release-notes-v${NEW_VERSION}.md
+<decision-gate>
 
-# Update release
-gh release edit "v${NEW_VERSION}" --notes-file /tmp/release-notes-v${NEW_VERSION}.md
+| Release Type | Action |
+|-------------|--------|
+| **patch** | ASK the user: "Would you like me to draft an enhanced summary highlighting the key bug fixes / changes? Or is the auto-generated changelog sufficient?" If user declines → skip to Step 8. If user accepts → draft a concise bug-fix / change summary below. |
+| **minor** | MANDATORY. Draft a concise feature summary. Do NOT proceed without one. |
+| **major** | MANDATORY. Draft a full release narrative with migration notes if applicable. Do NOT proceed without one. |
+
+</decision-gate>
+
+### What You're Writing (and What You're NOT)
+
+You are writing the **headline layer** — a product announcement that sits ABOVE the auto-generated commit log. Think "release blog post", not "git log".
+
+<rules>
+- NEVER duplicate commit messages. The auto-generated section already lists every commit.
+- NEVER write generic filler like "Various bug fixes and improvements" or "Several enhancements".
+- ALWAYS focus on USER IMPACT: what can users DO now that they couldn't before?
+- ALWAYS group by THEME or CAPABILITY, not by commit type (feat/fix/refactor).
+- ALWAYS use concrete language: "You can now do X" not "Added X feature".
+</rules>
+
+<examples>
+<bad title="Commit regurgitation — DO NOT do this">
+## What's New
+- feat(auth): add JWT refresh token rotation
+- fix(auth): handle expired token edge case
+- refactor(auth): extract middleware
+</bad>
+
+<good title="User-impact narrative — DO this">
+## 🔐 Smarter Authentication
+
+Token refresh is now automatic and seamless. Sessions no longer expire mid-task — the system silently rotates credentials in the background. If you've been frustrated by random logouts, this release fixes that.
+</good>
+
+<bad title="Vague filler — DO NOT do this">
+## Improvements
+- Various performance improvements
+- Bug fixes and stability enhancements
+</bad>
+
+<good title="Specific and measurable — DO this">
+## ⚡ 3x Faster Rule Parsing
+
+Rules are now cached by file modification time. If your project has 50+ rule files, you'll notice startup is noticeably faster — we measured a 3x improvement in our test suite.
+</good>
+</examples>
+
+### Drafting Process
+
+1. **Analyze** the commit list from Step 5's preview. Identify 2-5 themes that matter to users.
+2. **Write** the summary to `/tmp/release-summary-v${NEW_VERSION}.md`.
+3. **Present** the draft to the user for review and approval before applying.
+
+```bash
+# Write your draft here
+cat > /tmp/release-summary-v${NEW_VERSION}.md << 'SUMMARY_EOF'
+{your_enhanced_summary}

+---
+
+<MANDATORY_ARCHITECTURE_RULE severity="BLOCKING" priority="HIGHEST">
+
+# Modular Code Architecture — Zero Tolerance Policy
+
+This rule is NON-NEGOTIABLE. Violations BLOCK all further work until resolved.
+
+## Rule 1: index.ts is an ENTRY POINT, NOT a dumping ground
+
+`index.ts` files MUST ONLY contain:
+- Re-exports (`export { ... } from "./module"`)
+- Factory function calls that compose modules
+- Top-level wiring/registration (hook registration, plugin setup)
+
+`index.ts` MUST NEVER contain:
+- Business logic implementation
+- Helper/utility functions
+- Type definitions beyond simple re-exports
+- Multiple unrelated responsibilities mixed together
+
+**If you find mixed logic in index.ts**: Extract each responsibility into its own dedicated file BEFORE making any other changes. This is not optional.
+
+## Rule 2: No Catch-All Files — utils.ts / service.ts are CODE SMELLS
+
+A single `utils.ts`, `helpers.ts`, `service.ts`, or `common.ts` is a **gravity well** — every unrelated function gets tossed in, and it grows into an untestable, unreviewable blob.
+
+**These file names are BANNED as top-level catch-alls.** Instead:
+
+| Anti-Pattern | Refactor To |
+|--------------|-------------|
+| `utils.ts` with `formatDate()`, `slugify()`, `retry()` | `date-formatter.ts`, `slugify.ts`, `retry.ts` |
+| `service.ts` handling auth + billing + notifications | `auth-service.ts`, `billing-service.ts`, `notification-service.ts` |
+| `helpers.ts` with 15 unrelated exports | One file per logical domain |
+
+**Design for reusability from the start.** Each module should be:
+- **Independently importable** — no consumer should need to pull in unrelated code
+- **Self-contained** — its dependencies are explicit, not buried in a shared grab-bag
+- **Nameable by purpose** — the filename alone tells you what it does
+
+If you catch yourself typing `utils.ts` or `service.ts`, STOP and name the file after what it actually does.
+
+## Rule 3: Single Responsibility Principle — ABSOLUTE
+
+Every `.ts` file MUST have exactly ONE clear, nameable responsibility.
+
+**Self-test**: If you cannot describe the file's purpose in ONE short phrase (e.g., "parses YAML frontmatter", "matches rules against file paths"), the file does too much. Split it.
+
+| Signal | Action |
+|--------|--------|
+| File has 2+ unrelated exported functions | **SPLIT NOW** — each into its own module |
+| File mixes I/O with pure logic | **SPLIT NOW** — separate side effects from computation |
+| File has both types and implementation | **SPLIT NOW** — types.ts + implementation.ts |
+| You need to scroll to understand the file | **SPLIT NOW** — it's too large |
+
+## Rule 4: 200 LOC Hard Limit — CODE SMELL DETECTOR
+
+Any `.ts`/`.tsx` file exceeding **200 lines of code** (excluding prompt strings, template literals containing prompts, and `.md` content) is an **immediate code smell**.
+
+**When you detect a file > 200 LOC**:
+1. **STOP** current work
+2. **Identify** the multiple responsibilities hiding in the file
+3. **Extract** each responsibility into a focused module
+4. **Verify** each resulting file is < 200 LOC and has a single purpose
+5. **Resume** original work
+
+Prompt-heavy files (agent definitions, skill definitions) where the bulk of content is template literal prompt text are EXEMPT from the LOC count — but their non-prompt logic must still be < 200 LOC.
+
+### How to Count LOC
+
+**Count these** (= actual logic):
+- Import statements
+- Variable/constant declarations
+- Function/class/interface/type definitions
+- Control flow (`if`, `for`, `while`, `switch`, `try/catch`)
+- Expressions, assignments, return statements
+- Closing braces `}` that belong to logic blocks
+
+**Exclude these** (= not logic):
+- Blank lines
+- Comment-only lines (`//`, `/* */`, `/** */`)
+- Lines inside template literals that are prompt/instruction text (e.g., the string body of `` const prompt = `...` ``)
+- Lines inside multi-line strings used as documentation/prompt content
+
+**Quick method**: Read the file → subtract blank lines, comment-only lines, and prompt string content → remaining count = LOC.
+
+**Example**:
+```typescript
+// 1  import { foo } from "./foo";          ← COUNT
+// 2                                         ← SKIP (blank)
+// 3  // Helper for bar                      ← SKIP (comment)
+// 4  export function bar(x: number) {       ← COUNT
+// 5    const prompt = `                     ← COUNT (declaration)
+// 6      You are an assistant.              ← SKIP (prompt text)
+// 7      Follow these rules:                ← SKIP (prompt text)
+// 8    `;                                   ← COUNT (closing)
+// 9    return process(prompt, x);           ← COUNT
+// 10 }                                      ← COUNT
+```
+→ LOC = **5** (lines 1, 4, 5, 9, 10). Not 10.
+
+When in doubt, **round up** — err on the side of splitting.
+
+## How to Apply
+
+When reading, writing, or editing ANY `.ts`/`.tsx` file:
+
+1. **Check the file you're touching** — does it violate any rule above?
+2. **If YES** — refactor FIRST, then proceed with your task
+3. **If creating a new file** — ensure it has exactly one responsibility and stays under 200 LOC
+4. **If adding code to an existing file** — verify the addition doesn't push the file past 200 LOC or add a second responsibility. If it does, extract into a new module.

 ## MCP ARCHITECTURE
 
 Three-tier system:
-1. **Built-in**: websearch (Exa), context7 (docs), grep_app (GitHub)
-2. **Claude Code compat**: .mcp.json with `${VAR}` expansion
-3. **Skill-embedded**: YAML frontmatter in skills
+1. **Built-in** (src/mcp/): websearch (Exa/Tavily), context7 (docs), grep_app (GitHub)
+2. **Claude Code compat** (features/claude-code-mcp-loader/): .mcp.json with `${VAR}` expansion
+3. **Skill-embedded** (features/opencode-skill-loader/): YAML frontmatter in SKILL.md
 
 ## CONFIG SYSTEM
 
-- **Zod validation**: `src/config/schema.ts`
+- **Zod validation**: 21 schema component files in `src/config/schema/`
 - **JSONC support**: Comments, trailing commas
-- **Multi-level**: Project (`.opencode/`) → User (`~/.config/opencode/`)
+- **Multi-level**: Project (`.opencode/`) → User (`~/.config/opencode/`) → Defaults
+- **Migration**: Legacy config auto-migration in `src/shared/migration/`
 
 ## NOTES
 
 - **OpenCode**: Requires >= 1.0.150
+- **1069 TypeScript files**, 176 test files, 117k+ lines
 - **Flaky tests**: ralph-loop (CI timeout), session-state (parallel pollution)
 - **Trusted deps**: @ast-grep/cli, @ast-grep/napi, @code-yeongyu/comment-checker
+- **No linter/formatter**: No ESLint, Prettier, or Biome configured
+- **License**: SUL-1.0 (Sisyphus Use License)

-## 2. Overall Architecture
+## 2. Prometheus Invocation: Agent Switch vs @plan
+
+A common source of confusion is how to invoke Prometheus for planning. **Both methods achieve the same result** - use whichever feels natural.
+
+### Method 1: Switch to Prometheus Agent (Tab → Select Prometheus)
+
+```
+1. Press Tab at the prompt
+2. Select "Prometheus" from the agent list
+3. Describe your work: "I want to refactor the auth system"
+4. Answer interview questions
+5. Prometheus creates plan in .sisyphus/plans/{name}.md
+```
+
+### Method 2: Use @plan Command (in Sisyphus)
+
+```
+1. Stay in Sisyphus (default agent)
+2. Type: @plan "I want to refactor the auth system"
+3. The @plan command automatically switches to Prometheus
+4. Answer interview questions
+5. Prometheus creates plan in .sisyphus/plans/{name}.md
+```
+
+### Which Should You Use?
+
+| Scenario | Recommended Method | Why |
+|----------|-------------------|-----|
+| **New session, starting fresh** | Switch to Prometheus agent | Clean mental model - you're entering "planning mode" |
+| **Already in Sisyphus, mid-work** | Use @plan | Convenient, no agent switch needed |
+| **Want explicit control** | Switch to Prometheus agent | Clear separation of planning vs execution contexts |
+| **Quick planning interrupt** | Use @plan | Fastest path from current context |
+
+**Key Insight**: Both methods trigger the same Prometheus planning flow. The @plan command is simply a convenience shortcut that:
+1. Detects the `@plan` keyword in your message
+2. Routes the request to Prometheus automatically
+3. Returns you to Sisyphus after planning completes
+
+---
+
+## 3. /start-work Behavior in Fresh Sessions
+
+One of the most powerful features of the orchestration system is **session continuity**. Understanding how `/start-work` behaves across sessions prevents confusion.
+
+### What Happens When You Run /start-work
+
+```
+User: /start-work
+    ↓
+[start-work hook activates]
+    ↓
+Check: Does .sisyphus/boulder.json exist?
+    ↓
+    ├─ YES (existing work) → RESUME MODE
+    │   - Read the existing boulder state
+    │   - Calculate progress (checked vs unchecked boxes)
+    │   - Inject continuation prompt with remaining tasks
+    │   - Atlas continues where you left off
+    │
+    └─ NO (fresh start) → INIT MODE
+        - Find the most recent plan in .sisyphus/plans/
+        - Create new boulder.json tracking this plan
+        - Switch session agent to Atlas
+        - Begin execution from task 1
+```
+
+### Session Continuity Explained
+
+The `boulder.json` file tracks:
+- **active_plan**: Path to the current plan file
+- **session_ids**: All sessions that have worked on this plan
+- **started_at**: When work began
+- **plan_name**: Human-readable plan identifier
+
+**Example Timeline:**
+
+```
+Monday 9:00 AM
+  └─ @plan "Build user authentication"
+  └─ Prometheus interviews and creates plan
+  └─ User: /start-work
+  └─ Atlas begins execution, creates boulder.json
+  └─ Task 1 complete, Task 2 in progress...
+  └─ [Session ends - computer crash, user logout, etc.]
+
+Monday 2:00 PM (NEW SESSION)
+  └─ User opens new session (agent = Sisyphus by default)
+  └─ User: /start-work
+  └─ [start-work hook reads boulder.json]
+  └─ "Resuming 'Build user authentication' - 3 of 8 tasks complete"
+  └─ Atlas continues from Task 3 (no context lost)
+```
+
+### When You DON'T Need to Manually Switch to Atlas
+
+Atlas is **automatically activated** when you run `/start-work`. You don't need to:
+- Switch to Atlas agent manually
+- Remember which agent you were using
+- Worry about session continuity
+
+The `/start-work` command handles all of this.
+
+### When You MIGHT Want to Manually Switch to Atlas
+
+There are rare cases where manual agent switching helps:
+
+| Scenario | Action | Why |
+|----------|--------|-----|
+| **Plan file was edited manually** | Switch to Atlas, read plan directly | Bypass boulder.json resume logic |
+| **Debugging orchestration issues** | Switch to Atlas for visibility | See Atlas-specific system prompts |
+| **Force fresh execution** | Delete boulder.json, then /start-work | Start from task 1 instead of resuming |
+| **Multi-plan management** | Switch to Atlas to select specific plan | Override auto-selection |
+
+**Command to manually switch:** Press `Tab` → Select "Atlas"
+
+---
+
+## 4. Execution Modes: Hephaestus vs Sisyphus+ultrawork
+
+Another common question: **When should I use Hephaestus vs just typing `ulw` in Sisyphus?**
+
+### Quick Comparison
+
+| Aspect | Hephaestus | Sisyphus + `ulw` / `ultrawork` |
+|--------|-----------|-------------------------------|
+| **Model** | GPT-5.2 Codex (medium reasoning) | Claude Opus 4.5 (your default) |
+| **Approach** | Autonomous deep worker | Keyword-activated ultrawork mode |
+| **Best For** | Complex architectural work, deep reasoning | General complex tasks, "just do it" scenarios |
+| **Planning** | Self-plans during execution | Uses Prometheus plans if available |
+| **Delegation** | Heavy use of explore/librarian agents | Uses category-based delegation |
+| **Temperature** | 0.1 | 0.1 |
+
+### When to Use Hephaestus
+
+Switch to Hephaestus (Tab → Select Hephaestus) when:
+
+1. **Deep architectural reasoning needed**
+   - "Design a new plugin system"
+   - "Refactor this monolith into microservices"
+
+2. **Complex debugging requiring inference chains**
+   - "Why does this race condition only happen on Tuesdays?"
+   - "Trace this memory leak through 15 files"
+
+3. **Cross-domain knowledge synthesis**
+   - "Integrate our Rust core with the TypeScript frontend"
+   - "Migrate from MongoDB to PostgreSQL with zero downtime"
+
+4. **You specifically want GPT-5.2 Codex reasoning**
+   - Some problems benefit from GPT-5.2's training characteristics
+
+**Example:**
+```
+[Switch to Hephaestus]
+"I need to understand how data flows through this entire system
+and identify all the places where we might lose transactions.
+Explore thoroughly before proposing fixes."
+```
+
+### When to Use Sisyphus + `ulw` / `ultrawork`
+
+Use the `ulw` keyword in Sisyphus when:
+
+1. **You want the agent to figure it out**
+   - "ulw fix the failing tests"
+   - "ulw add input validation to the API"
+
+2. **Complex but well-scoped tasks**
+   - "ulw implement JWT authentication following our patterns"
+   - "ulw create a new CLI command for deployments"
+
+3. **You're feeling lazy** (officially supported use case)
+   - Don't want to write detailed requirements
+   - Trust the agent to explore and decide
+
+4. **You want to leverage existing plans**
+   - If a Prometheus plan exists, `ulw` mode can use it
+   - Falls back to autonomous exploration if no plan
+
+**Example:**
+```
+[Stay in Sisyphus]
+"ulw refactor the user service to use the new repository pattern"
+
+[Agent automatically:]
+- Explores existing codebase patterns
+- Implements the refactor
+- Runs verification (tests, typecheck)
+- Reports completion
+```
+
+### Key Difference in Practice
+
+| Hephaestus | Sisyphus + ulw |
+|------------|----------------|
+| You manually switch to Hephaestus agent | You type `ulw` in any Sisyphus session |
+| GPT-5.2 Codex with medium reasoning | Your configured default model |
+| Optimized for autonomous deep work | Optimized for general execution |
+| Always uses explore-first approach | Respects existing plans if available |
+| "Smart intern that needs no supervision" | "Smart intern that follows your workflow" |
+
+### Recommendation
+
+**For most users**: Use `ulw` keyword in Sisyphus. It's the default path and works excellently for 90% of complex tasks.
+
+**For power users**: Switch to Hephaestus when you specifically need GPT-5.2 Codex's reasoning style or want the "AmpCode deep mode" experience of fully autonomous exploration and execution.

 2. **Task Execution**: Atlas reads the plan and processes TODOs one by one.

+## 8. Commands and Usage
 
 ### `@plan [request]`
 
-Invokes Prometheus to start a planning session.
+Invokes Prometheus to start a planning session from Sisyphus.
 
 - Example: `@plan "I want to refactor the authentication system to NextAuth"`
+- Effect: Routes to Prometheus, then returns to Sisyphus when planning completes
 
 ### `/start-work`
 
 Executes the generated plan.
 
-- Function: Finds plan in `.sisyphus/plans/` and enters execution mode.
-- If there's interrupted work, automatically resumes from where it left off.
+- **Fresh session**: Finds plan in `.sisyphus/plans/` and enters execution mode
+- **Existing boulder**: Resumes from where you left off (reads boulder.json)
+- **Effect**: Automatically switches to Atlas agent if not already active
+
+### Switching Agents Manually
+
+Press `Tab` at the prompt to see available agents:
+
+| Agent | When to Switch |
+|-------|---------------|
+| **Prometheus** | You want to create a detailed work plan |
+| **Atlas** | You want to manually control plan execution (rare) |
+| **Hephaestus** | You need GPT-5.2 Codex for deep autonomous work |
+| **Sisyphus** | Return to default agent for normal prompting |

+

+
+## 11. Troubleshooting Common Confusions
+
+### "I switched to Prometheus but nothing happened"
+
+Prometheus enters **interview mode** by default. It will ask you questions about your requirements. Answer them, then say "make it a plan" when ready.
+
+### "/start-work says 'no active plan found'"
+
+Either:
+- No plans exist in `.sisyphus/plans/` → Create one with Prometheus first
+- Plans exist but boulder.json points elsewhere → Delete `.sisyphus/boulder.json` and retry
+
+### "I'm in Atlas but I want to switch back to normal mode"
+
+Type `exit` or start a new session. Atlas is primarily entered via `/start-work` - you don't typically "switch to Atlas" manually.
+
+### "What's the difference between @plan and just switching to Prometheus?"
+
+**Nothing functional.** Both invoke Prometheus. @plan is a convenience command while switching agents is explicit control. Use whichever feels natural.
+
+### "Should I use Hephaestus or type ulw?"
+
+**For most tasks**: Type `ulw` in Sisyphus.
+
+**Use Hephaestus when**: You specifically need GPT-5.2 Codex's reasoning style for deep architectural work or complex debugging.

+# Issue #1501 분석 보고서: ULW Mode PLAN AGENT 무한루프
+
+## 📋 이슈 요약
+
+**증상:**
+- ULW (ultrawork) mode에서 PLAN AGENT가 무한루프에 빠짐
+- 분석/탐색 완료 후 plan만 계속 생성
+- 1분마다 매우 작은 토큰으로 요청 발생
+
+**예상 동작:**
+- 탐색 완료 후 solution document 생성
+
+---
+
+## 🔍 근본 원인 분석
+
+### 파일: `src/tools/delegate-task/constants.ts`
+
+#### 문제의 핵심
+
+`PLAN_AGENT_SYSTEM_PREPEND` (constants.ts 234-269행)에 구조적 결함이 있었습니다:
+
+1. **Interactive Mode 가정**
+   ```
+   2. After gathering context, ALWAYS present:
+      - Uncertainties: List of unclear points
+      - Clarifying Questions: Specific questions to resolve uncertainties
+   
+   3. ITERATE until ALL requirements are crystal clear:
+      - Do NOT proceed to planning until you have 100% clarity
+      - Ask the user to confirm your understanding
+   ```
+
+2. **종료 조건 없음**
+   - "100% clarity" 요구는 객관적 측정 불가능
+   - 사용자 확인 요청은 ULW mode에서 불가능
+   - 무한루프로 이어짐
+
+3. **ULW Mode 미감지**
+   - Subagent로 실행되는 경우를 구분하지 않음
+   - 항상 interactive mode로 동작 시도
+
+### 왜 무한루프가 발생했는가?
+
+```
+ULW Mode 시작
+  → Sisyphus가 Plan Agent 호출 (subagent)
+    → Plan Agent: "100% clarity 필요"
+      → Clarifying questions 생성
+        → 사용자 없음 (subagent)
+          → 다시 plan 생성 시도
+            → "여전히 unclear"
+              → 무한루프 반복
+```
+
+**핵심:** Plan Agent는 사용자와 대화하도록 설계되었지만, ULW mode에서는 사용자가 없는 subagent로 실행됨.
+
+---
+
+## ✅ 적용된 수정 방안
+
+### 수정 내용 (constants.ts)
+
+#### 1. SUBAGENT MODE DETECTION 섹션 추가
+
+```typescript
+SUBAGENT MODE DETECTION (CRITICAL):
+If you received a detailed prompt with gathered context from a parent orchestrator (e.g., Sisyphus):
+- You are running as a SUBAGENT
+- You CANNOT directly interact with the user
+- DO NOT ask clarifying questions - proceed with available information
+- Make reasonable assumptions for minor ambiguities
+- Generate the plan based on the provided context
+```
+
+#### 2. Context Gathering Protocol 수정
+
+```diff
+- 1. Launch background agents to gather context:
++ 1. Launch background agents to gather context (ONLY if not already provided):
+```
+
+**효과:** 이미 Sisyphus가 context를 수집한 경우 중복 방지
+
+#### 3. Clarifying Questions → Assumptions
+
+```diff
+- 2. After gathering context, ALWAYS present:
+-    - Uncertainties: List of unclear points
+-    - Clarifying Questions: Specific questions
++ 2. After gathering context, assess clarity:
++    - User Request Summary: Concise restatement
++    - Assumptions Made: List any assumptions for unclear points
+```
+
+**효과:** 질문 대신 가정 사항 문서화
+
+#### 4. 무한루프 방지 - 명확한 종료 조건
+
+```diff
+- 3. ITERATE until ALL requirements are crystal clear:
+-    - Do NOT proceed to planning until you have 100% clarity
+-    - Ask the user to confirm your understanding
+-    - Resolve every ambiguity before generating the work plan
++ 3. PROCEED TO PLAN GENERATION when:
++    - Core objective is understood (even if some details are ambiguous)
++    - You have gathered context via explore/librarian (or context was provided)
++    - You can make reasonable assumptions for remaining ambiguities
++    
++    DO NOT loop indefinitely waiting for perfect clarity.
++    DOCUMENT assumptions in the plan so they can be validated during execution.
+```
+
+**효과:**
+- "100% clarity" 요구 제거
+- 객관적인 진입 조건 제공
+- 무한루프 명시적 금지
+- Assumptions를 plan에 문서화하여 실행 중 검증 가능
+
+#### 5. 철학 변경
+
+```diff
+- REMEMBER: Vague requirements lead to failed implementations.
++ REMEMBER: A plan with documented assumptions is better than no plan.
+```
+
+**효과:** Perfectionism → Pragmatism
+

+- Subagent mode일 때만 다르게 동작
+- Backward compatibility 유지
+
+### 추가 개선사항
+
+- Assumptions를 plan에 명시적으로 문서화
+- Execution 중 validation 가능

+### 테스트 시나리오
+
+1. **ULW mode에서 Plan Agent 호출**
+   ```bash
+   oh-my-opencode run "Complex task requiring planning. ulw"
+   ```
+   - 예상: Plan 생성 후 정상 종료
+   - 확인: 무한루프 없음
+
+2. **Interactive mode (변경 없어야 함)**
+   ```bash
+   oh-my-opencode run --agent prometheus "Design X"
+   ```
+   - 예상: Clarifying questions 여전히 가능
+   - 확인: 사용자와 대화 가능
+
+3. **Subagent context 제공 케이스**
+   - 예상: Context gathering skip
+   - 확인: 중복 탐색 없음

+
+## ✅ Conclusion
+
+**Root Cause:** Plan Agent가 interactive mode를 가정했으나 ULW mode에서는 subagent로 실행되어 사용자 상호작용 불가능. "100% clarity" 요구로 무한루프 발생.
+
+**Solution:** Subagent mode 감지 로직 추가, clarifying questions 제거, 명확한 종료 조건 제공, assumptions 문서화 방식 도입.
+
+**Result:** ULW mode에서 Plan Agent가 정상적으로 plan 생성 후 종료. 무한루프 해결.

+
+## PLUGIN INITIALIZATION (10 steps)
+
+1. `injectServerAuthIntoClient(ctx.client)` — Auth injection
+2. `startTmuxCheck()` — Tmux availability
+3. `loadPluginConfig(ctx.directory, ctx)` — User + project config merge → Zod validation
+4. `createFirstMessageVariantGate()` — First message variant override gate
+5. `createModelCacheState()` — Model context limits cache
+6. `createManagers(...)` → 4 managers:
+   - `TmuxSessionManager` — Multi-pane tmux sessions
+   - `BackgroundManager` — Parallel subagent execution
+   - `SkillMcpManager` — MCP server lifecycle
+   - `ConfigHandler` — Plugin config API to OpenCode
+7. `createTools(...)` → `createSkillContext()` + `createAvailableCategories()` + `createToolRegistry()`
+8. `createHooks(...)` → `createCoreHooks()` + `createContinuationHooks()` + `createSkillHooks()`
+9. `createPluginInterface(...)` → 7 OpenCode hook handlers
+10. Return plugin with `experimental.session.compacting`
+
+## HOOK REGISTRATION (3 tiers)
+
+**Core Hooks** (`create-core-hooks.ts`):
+- Session (20): context-window-monitor, session-recovery, think-mode, ralph-loop, anthropic-effort, ...
+- Tool Guard (8): comment-checker, tool-output-truncator, rules-injector, write-existing-file-guard, ...
+- Transform (4): claude-code-hooks, keyword-detector, context-injector, thinking-block-validator
+
+**Continuation Hooks** (`create-continuation-hooks.ts`):
+- 7 hooks: stop-continuation-guard, compaction-context-injector, todo-continuation-enforcer, atlas, ...
+
+**Skill Hooks** (`create-skill-hooks.ts`):
+- 2 hooks: category-skill-reminder, auto-slash-command
+
+## PLUGIN INTERFACE (7 OpenCode handlers)
+
+| Handler | Source | Purpose |
+|---------|--------|---------|
+| `tool` | filteredTools | All registered tools |
+| `chat.params` | createChatParamsHandler | Anthropic effort level |
+| `chat.message` | createChatMessageHandler | First message variant, session setup |
+| `experimental.chat.messages.transform` | createMessagesTransformHandler | Context injection, keyword detection |
+| `config` | configHandler | Agent/MCP/command registration |
+| `event` | createEventHandler | Session lifecycle |
+| `tool.execute.before` | createToolExecuteBeforeHandler | Pre-tool hooks |
+| `tool.execute.after` | createToolExecuteAfterHandler | Post-tool hooks |
+
+## SAFE HOOK CREATION PATTERN
+
+```typescript
+const hook = isHookEnabled("hook-name")
+  ? safeCreateHook("hook-name", () => createHookFactory(ctx), { enabled: safeHookEnabled })
+  : null;
+```
+
+All hooks use this pattern for graceful degradation on failure.

 ## OVERVIEW
 
-11 AI agents for multi-model orchestration. Each agent has factory function + metadata + fallback chains.
-
-**Primary Agents** (respect UI model selection):
-- Sisyphus, Atlas, Prometheus
-
-**Subagents** (use own fallback chains):
-- Hephaestus, Oracle, Librarian, Explore, Multimodal-Looker, Metis, Momus, Sisyphus-Junior
+11 AI agents with factory functions, fallback chains, and model-specific prompt variants. Each agent has metadata (category, cost, triggers) and configurable tool restrictions.

 ## TOOL RESTRICTIONS
-| Agent | Denied Tools |
-|-------|-------------|
-| oracle | write, edit, task, delegate_task |
-| librarian | write, edit, task, delegate_task, call_omo_agent |
-| explore | write, edit, task, delegate_task, call_omo_agent |
-| multimodal-looker | Allowlist: read only |
-| Sisyphus-Junior | task, delegate_task |
 
-## PATTERNS
-- **Factory**: `createXXXAgent(model: string): AgentConfig`
-- **Metadata**: `XXX_PROMPT_METADATA` with category, cost, triggers.
-- **Tool restrictions**: `createAgentToolRestrictions(tools)` or `createAgentToolAllowlist(tools)`.
-- **Thinking**: 32k budget tokens for Sisyphus, Oracle, Prometheus, Atlas.
+| Agent | Denied | Allowed |
+|-------|--------|---------|
+| oracle | write, edit, task, call_omo_agent | Read-only consultation |
+| librarian | write, edit, task, call_omo_agent | Research tools only |
+| explore | write, edit, task, call_omo_agent | Search tools only |
+| multimodal-looker | ALL except `read` | Vision-only |
+| Sisyphus-Junior | task | No delegation |
+| Atlas | task, call_omo_agent | Orchestration only |
+
+## THINKING / REASONING
+
+| Agent | Claude | GPT |
+|-------|--------|-----|
+| Sisyphus | 32k budget tokens | reasoningEffort: "medium" |
+| Hephaestus | — | reasoningEffort: "medium" |
+| Oracle | 32k budget tokens | reasoningEffort: "medium" |
+| Metis | 32k budget tokens | — |
+| Momus | 32k budget tokens | reasoningEffort: "medium" |
+| Sisyphus-Junior | 32k budget tokens | reasoningEffort: "medium" |
+
+## HOW TO ADD
+
+1. Create `src/agents/my-agent.ts` exporting factory + metadata
+2. Add to `agentSources` in `src/agents/builtin-agents/`
+3. Update `AgentNameSchema` in `src/config/schema/agent-names.ts`
+4. Register in `src/plugin-handlers/agent-config-handler.ts`
+
+## KEY PATTERNS
+
+- **Factory**: `createXXXAgent(model): AgentConfig`
+- **Metadata**: `XXX_PROMPT_METADATA` with category, cost, triggers
+- **Model-specific prompts**: Atlas, Sisyphus-Junior have GPT vs Claude variants
+- **Dynamic prompts**: Sisyphus, Hephaestus use `dynamic-agent-prompt-builder.ts` to inject available tools/skills/categories
 
 ## ANTI-PATTERNS
-- **Trust reports**: NEVER trust "I'm done" - verify outputs.
-- **High temp**: Don't use >0.3 for code agents.
-- **Sequential calls**: Use `delegate_task` with `run_in_background` for exploration.
-- **Prometheus writing code**: Planner only - never implements.

+#### A. Automated Verification
+1. \`lsp_diagnostics(filePath=".")\` → ZERO errors at project level

-4. **Manual inspection**:
-   - Read changed files
-   - Confirm changes match requirements
-   - Check for regressions
+**This is the step you are most tempted to skip. DO NOT SKIP IT.**
 
-**Checklist:**
+1. \`Read\` EVERY file the subagent created or modified — no exceptions
+2. For EACH file, check line by line:
+   - Does the logic actually implement the task requirement?
+   - Are there stubs, TODOs, placeholders, or hardcoded values?
+   - Are there logic errors or missing edge cases?
+   - Does it follow the existing codebase patterns?
+   - Are imports correct and complete?
+3. Cross-reference: compare what subagent CLAIMED vs what the code ACTUALLY does
+4. If anything doesn't match → resume session and fix immediately

 ## COMMANDS
 
-| Command | Purpose |
-|---------|---------|
-| `install` | Interactive setup with provider selection |
-| `doctor` | 14 health checks for diagnostics |
-| `run` | Launch session with todo enforcement |
-| `get-local-version` | Version detection and update check |
+| Command | Purpose | Key Logic |
+|---------|---------|-----------|
+| `install` | Interactive setup | Provider selection → config generation → plugin registration |
+| `run` | Session launcher | Agent: flag → env → config → Sisyphus. Enforces todo completion. |
+| `doctor` | 14 health checks | installation, config, auth, deps, tools, updates |
+| `get-local-version` | Version check | Detects installed, compares with npm latest |
+| `mcp-oauth` | OAuth tokens | login (PKCE flow), logout, status |
 
-## DOCTOR CATEGORIES (14 Checks)
+## DOCTOR CHECK CATEGORIES
 
 | Category | Checks |
 |----------|--------|
 | installation | opencode, plugin |
-| configuration | config validity, Zod, model-resolution |
+| configuration | config validity, Zod, model-resolution (6 sub-checks) |
 | authentication | anthropic, openai, google |
 | dependencies | ast-grep, comment-checker, gh-cli |
-| tools | LSP, MCP |
+| tools | LSP, MCP, MCP-OAuth |
 | updates | version comparison |
 
 ## HOW TO ADD CHECK
 
 1. Create `src/cli/doctor/checks/my-check.ts`
-2. Export `getXXXCheckDefinition()` factory returning `CheckDefinition`
+2. Export `getXXXCheckDefinition()` returning `CheckDefinition`
 3. Add to `getAllCheckDefinitions()` in `checks/index.ts`
 
-## TUI FRAMEWORK
-
-- **@clack/prompts**: `select()`, `spinner()`, `intro()`, `outro()`
-- **picocolors**: Terminal colors for status and headers
-- **Symbols**: ✓ (pass), ✗ (fail), ⚠ (warn), ℹ (info)
-
 ## ANTI-PATTERNS
 
-- **Blocking in non-TTY**: Always check `process.stdout.isTTY`
-- **Direct JSON.parse**: Use `parseJsonc()` from shared utils
-- **Silent failures**: Return `warn` or `fail` in doctor instead of throwing
-- **Hardcoded paths**: Use `getOpenCodeConfigPaths()` from `config-manager.ts`
+- **Blocking in non-TTY**: Check `process.stdout.isTTY`
+- **Direct JSON.parse**: Use `parseJsonc()` from shared
+- **Silent failures**: Return `warn` or `fail` in doctor, don't throw
+- **Hardcoded paths**: Use `getOpenCodeConfigPaths()` from config-manager

- * Antigravity Provider Configuration
- *
- * IMPORTANT: Model names MUST use `antigravity-` prefix for stability.
- *
- * Since opencode-antigravity-auth v1.3.0, models use a variant system:
- * - `antigravity-gemini-3-pro` with variants: low, high
- * - `antigravity-gemini-3-flash` with variants: minimal, low, medium, high
- *
- * Legacy tier-suffixed names (e.g., `antigravity-gemini-3-pro-high`) still work
- * but variants are the recommended approach.
