release: v3.7.1

Convert all markdown tables in Sisyphus and dynamic-agent-prompt-builder
to plain bullet lists for cleaner prompt rendering.

Add explicit Oracle safeguards:
- Hard Block: background_cancel(all=true) when Oracle running
- Hard Block: delivering final answer before collecting Oracle result
- Anti-Pattern: background_cancel(all=true) and skipping Oracle
- Oracle section: NEVER cancel, collect via background_output first
- Background Result Collection: split cancel/wait into separate steps
  with explicit NEVER use background_cancel(all=true) instruction

 <command-instruction>
-You are a dead code removal specialist. Execute the FULL dead code removal workflow using ultrawork mode.
 
-Your core weapon: **LSP FindReferences**. If a symbol has ZERO external references, it's dead. Remove it.
+Dead code removal via massively parallel deep agents. You are the ORCHESTRATOR — you scan, verify, batch, then delegate ALL removals to parallel agents.
 
-## CRITICAL RULES
+<rules>
+- **LSP is law.** Verify with `LspFindReferences(includeDeclaration=false)` before ANY removal decision.
+- **Never remove entry points.** `src/index.ts`, `src/cli/index.ts`, test files, config files, `packages/` — off-limits.
+- **You do NOT remove code yourself.** You scan, verify, batch, then fire deep agents. They do the work.
+</rules>
 
-1. **LSP is law.** Never guess. Always verify with `LspFindReferences` before removing ANYTHING.
-2. **One removal = one commit.** Every dead code removal gets its own atomic commit.
-3. **Test after every removal.** Run `bun test` after each. If it fails, REVERT and skip.
-4. **Leaf-first order.** Remove deepest unused symbols first, then work up the dependency chain. Removing a leaf may expose new dead code upstream.
-5. **Never remove entry points.** `src/index.ts`, `src/cli/index.ts`, test files, config files, and files in `packages/` are off-limits unless explicitly targeted.
+<false-positive-guards>
+NEVER mark as dead:
+- Symbols in `src/index.ts` or barrel `index.ts` re-exports
+- Symbols referenced in test files (tests are valid consumers)
+- Symbols with `@public` / `@api` JSDoc tags
+- Hook factories (`createXXXHook`), tool factories (`createXXXTool`), agent definitions in `agentSources`
+- Command templates, skill definitions, MCP configs
+- Symbols in `package.json` exports
+</false-positive-guards>

----
+<parallel-scan>
 
-## PHASE 1: SCAN FOR DEAD CODE CANDIDATES
-
-**Mark scan as in_progress.**
-
-### 1.1: Launch Parallel Explore Agents (ALL BACKGROUND)
-
-Fire ALL simultaneously:
-
-```
-// Agent 1: Find all exported symbols
-task(subagent_type="explore", run_in_background=true,
-  prompt="Find ALL exported functions, classes, types, interfaces, and constants across src/.
-  List each with: file path, line number, symbol name, export type (named/default).
-  EXCLUDE: src/index.ts root exports, test files.
-  Return as structured list.")
-
-// Agent 2: Find potentially unused files
-task(subagent_type="explore", run_in_background=true,
-  prompt="Find files in src/ that are NOT imported by any other file.
-  Check import/require statements across the entire codebase.
-  EXCLUDE: index.ts files, test files, entry points, config files, .md files.
-  Return list of potentially orphaned files.")
-
-// Agent 3: Find unused imports within files
-task(subagent_type="explore", run_in_background=true,
-  prompt="Find unused imports across src/**/*.ts files.
-  Look for import statements where the imported symbol is never referenced in the file body.
-  Return: file path, line number, imported symbol name.")
-
-// Agent 4: Find functions/variables only used in their own declaration
-task(subagent_type="explore", run_in_background=true,
-  prompt="Find private/non-exported functions, variables, and types in src/**/*.ts that appear
-  to have zero usage beyond their declaration. Return: file path, line number, symbol name.")
-```
-
-### 1.2: Direct AST-Grep Scans (WHILE AGENTS RUN)
-
-```typescript
-// Find unused imports pattern
-ast_grep_search(pattern="import { $NAME } from '$PATH'", lang="typescript", paths=["src/"])
-
-// Find empty export objects
-ast_grep_search(pattern="export {}", lang="typescript", paths=["src/"])
-```
-
-### 1.3: Collect All Results
-
-Collect background agent results. Compile into a master candidate list:
-
-```
-## DEAD CODE CANDIDATES
-
-| # | File | Line | Symbol | Type | Confidence |
-|---|------|------|--------|------|------------|
-| 1 | src/foo.ts | 42 | unusedFunc | function | HIGH |
-| 2 | src/bar.ts | 10 | OldType | type | MEDIUM |
-```
-
-**Mark scan as completed.**
-
----
-
-## PHASE 2: VERIFY WITH LSP (ZERO FALSE POSITIVES)
-
-**Mark verify as in_progress.**
-
-For EVERY candidate from Phase 1, run this verification:
-
-### 2.1: The LSP Verification Protocol
-
-For each candidate symbol:
-
-```typescript
-// Step 1: Find the symbol's exact position
-LspDocumentSymbols(filePath)  // Get line/character of the symbol
-
-// Step 2: Find ALL references across the ENTIRE workspace
-LspFindReferences(filePath, line, character, includeDeclaration=false)
-// includeDeclaration=false → only counts USAGES, not the definition itself
-
-// Step 3: Evaluate
-// 0 references → CONFIRMED DEAD CODE
-// 1+ references → NOT dead, remove from candidate list
-```
-
-### 2.2: False Positive Guards
-
-**NEVER mark as dead code if:**
-- Symbol is in `src/index.ts` (package entry point)
-- Symbol is in any `index.ts` that re-exports (barrel file check: look if it's re-exported)
-- Symbol is referenced in test files (tests are valid consumers)
-- Symbol has `@public` or `@api` JSDoc tags
-- Symbol is in a file listed in `package.json` exports
-- Symbol is a hook factory (`createXXXHook`) registered in `src/index.ts`
-- Symbol is a tool factory (`createXXXTool`) registered in tool loading
-- Symbol is an agent definition registered in `agentSources`
-- File is a command template, skill definition, or MCP config
-
-### 2.3: Build Confirmed Dead Code List
-
-After verification, produce:
-
-```
-## CONFIRMED DEAD CODE (LSP-verified, 0 external references)
-
-| # | File | Line | Symbol | Type | Safe to Remove |
-|---|------|------|--------|------|----------------|
-| 1 | src/foo.ts | 42 | unusedFunc | function | YES |
-```
-
-**If ZERO confirmed dead code found: Report "No dead code found" and STOP.**
-
-**Mark verify as completed.**
-
----
-
-## PHASE 3: PLAN REMOVAL ORDER
-
-**Mark plan as in_progress.**
-
-### 3.1: Dependency Analysis
-
-For each confirmed dead symbol:
-1. Check if removing it would expose other dead code
-2. Check if other dead symbols depend on this one
-3. Build removal dependency graph
-
-### 3.2: Order by Leaf-First
-
-```
-Removal Order:
-1. [Leaf symbols - no other dead code depends on them]
-2. [Intermediate symbols - depended on only by already-removed dead code]
-3. [Dead files - entire files with no live exports]
-```
-
-### 3.3: Register Granular Todos
-
-Create one todo per removal:
-
-```
-TodoWrite([
-  {"id": "remove-1", "content": "Remove unusedFunc from src/foo.ts:42", "status": "pending", "priority": "high"},
-  {"id": "remove-2", "content": "Remove OldType from src/bar.ts:10", "status": "pending", "priority": "high"},
-  // ... one per confirmed dead symbol
-])
-```
-
-**Mark plan as completed.**
-
----
-
-## PHASE 4: ITERATIVE REMOVAL LOOP
-
-**Mark remove as in_progress.**
-
-For EACH dead code item, execute this exact loop:
-
-### 4.1: Pre-Removal Check
-
-```typescript
-// Re-verify it's still dead (previous removals may have changed things)
-LspFindReferences(filePath, line, character, includeDeclaration=false)
-// If references > 0 now → SKIP (previous removal exposed a new consumer)
-```
-
-### 4.2: Remove the Dead Code
-
-Use appropriate tool:
-
-**For unused imports:**
-```typescript
-Edit(filePath, oldString="import { deadSymbol } from '...';\n", newString="")
-// Or if it's one of many imports, remove just the symbol from the import list
-```
-
-**For unused functions/classes/types:**
-```typescript
-// Read the full symbol extent first
-Read(filePath, offset=startLine, limit=endLine-startLine+1)
-// Then remove it
-Edit(filePath, oldString="[full symbol text]", newString="")
-```
-
-**For dead files:**
+**TypeScript strict mode (your primary scanner — run this FIRST):**
 ```bash
-# Only after confirming ZERO imports point to this file
-rm "path/to/dead-file.ts"
+bunx tsc --noEmit --noUnusedLocals --noUnusedParameters 2>&1
+```
+This gives you the definitive list of unused locals, imports, parameters, and types with exact file:line locations.
+
+**Explore agents (fire ALL simultaneously as background):**
+
+```
+task(subagent_type="explore", run_in_background=true, load_skills=[],
+  description="Find orphaned files",
+  prompt="Find files in src/ NOT imported by any other file. Check all import statements. EXCLUDE: index.ts, *.test.ts, entry points, .md, packages/. Return: file paths.")
+
+task(subagent_type="explore", run_in_background=true, load_skills=[],
+  description="Find unused exported symbols",
+  prompt="Find exported functions/types/constants in src/ that are never imported by other files. Cross-reference: for each export, grep the symbol name across src/ — if it only appears in its own file, it's a candidate. EXCLUDE: src/index.ts exports, test files. Return: file path, line, symbol name, export type.")
 ```
 
-**After removal, also clean up:**
-- Remove any imports that were ONLY used by the removed code
-- Remove any now-empty import statements
-- Fix any trailing whitespace / double blank lines left behind
+</parallel-scan>
 
-### 4.3: Post-Removal Verification
+Collect all results into a master candidate list.
+
+---
+
+## PHASE 2: VERIFY — LSP Confirmation (Zero False Positives)
+
+For EACH candidate from Phase 1:
 
 ```typescript
-// 1. LSP diagnostics on changed file
-LspDiagnostics(filePath, severity="error")
-// Must be clean (or only pre-existing errors)
-
-// 2. Run tests
-bash("bun test")
-// Must pass
-
-// 3. Typecheck
-bash("bun run typecheck")
-// Must pass
+LspFindReferences(filePath, line, character, includeDeclaration=false)
+// 0 references → CONFIRMED dead
+// 1+ references → NOT dead, drop from list
 ```
 
-### 4.4: Handle Failures
+Also apply the false-positive-guards above. Produce a confirmed list:
 
-If ANY verification fails:
-1. **REVERT** the change immediately (`git checkout -- [file]`)
-2. Mark this removal todo as `cancelled` with note: "Removal caused [error]. Skipped."
-3. Proceed to next item
-
-### 4.5: Commit
-
-```bash
-git add [changed-files]
-git commit -m "refactor: remove unused [symbolType] [symbolName] from [filePath]"
+```
+| # | File | Symbol | Type | Action |
+|---|------|--------|------|--------|
+| 1 | src/foo.ts:42 | unusedFunc | function | REMOVE |
+| 2 | src/bar.ts:10 | OldType | type | REMOVE |
+| 3 | src/baz.ts:7 | ctx | parameter | PREFIX _ |
 ```
 
-Mark this removal todo as `completed`.
+**Action types:**
+- `REMOVE` — delete the symbol/import/file entirely
+- `PREFIX _` — unused function parameter required by signature → rename to `_paramName`
 
-### 4.6: Re-scan After Removal
+If ZERO confirmed: report "No dead code found" and STOP.
 
-After removing a symbol, check if its removal exposed NEW dead code:
-- Were there imports that only existed to serve the removed symbol?
-- Are there other symbols in the same file now unreferenced?
+---
 
-If new dead code is found, add it to the removal queue.
+## PHASE 3: BATCH — Group by File for Conflict-Free Parallelism
 
-**Repeat 4.1-4.6 for every item. Mark remove as completed when done.**
+<batching-rules>
+
+**Goal: maximize parallel agents with ZERO git conflicts.**
+
+1. Group confirmed dead code items by FILE PATH
+2. All items in the SAME file go to the SAME batch (prevents two agents editing the same file)
+3. If a dead FILE (entire file deletion) exists, it's its own batch
+4. Target 5-15 batches. If fewer than 5 items total, use 1 batch per item.
+
+**Example batching:**
+```
+Batch A: [src/hooks/foo/hook.ts — 3 unused imports]
+Batch B: [src/features/bar/manager.ts — 2 unused constants, 1 dead function]
+Batch C: [src/tools/baz/tool.ts — 1 unused param, src/tools/baz/types.ts — 1 unused type]
+Batch D: [src/dead-file.ts — entire file deletion]
+```
+
+Files in the same directory CAN be batched together (they won't conflict as long as no two agents edit the same file). Maximize batch count for parallelism.
+
+</batching-rules>
+
+---
+
+## PHASE 4: EXECUTE — Fire Parallel Deep Agents
+
+For EACH batch, fire a deep agent:
+
+```
+task(
+  category="deep",
+  load_skills=["typescript-programmer", "git-master"],
+  run_in_background=true,
+  description="Remove dead code batch N: [brief description]",
+  prompt="[see template below]"
+)
+```
+
+<agent-prompt-template>
+
+Every deep agent gets this prompt structure (fill in the specifics per batch):
+
+```
+## TASK: Remove dead code from [file list]
+
+## DEAD CODE TO REMOVE
+
+### [file path] line [N]
+- Symbol: `[name]` — [type: unused import / unused constant / unused function / unused parameter / dead file]
+- Action: [REMOVE entirely / REMOVE from import list / PREFIX with _]
+
+### [file path] line [N]
+- ...
+
+## PROTOCOL
+
+1. Read each file to understand exact syntax at the target lines
+2. For each symbol, run LspFindReferences to RE-VERIFY it's still dead (another agent may have changed things)
+3. Apply the change:
+   - Unused import (only symbol in line): remove entire import line
+   - Unused import (one of many): remove only that symbol from the import list
+   - Unused constant/function/type: remove the declaration. Clean up trailing blank lines.
+   - Unused parameter: prefix with `_` (do NOT remove — required by signature)
+   - Dead file: delete with `rm`
+4. After ALL edits in this batch, run: `bun run typecheck`
+5. If typecheck fails: `git checkout -- [files]` and report failure
+6. If typecheck passes: stage ONLY your files and commit:
+   `git add [your-specific-files] && git commit -m "refactor: remove dead code from [brief file list]"`
+7. Report what you removed and the commit hash
+
+## CRITICAL
+- Stage ONLY your batch's files (`git add [specific files]`). NEVER `git add -A` — other agents are working in parallel.
+- If typecheck fails after your edits, REVERT all changes and report. Do not attempt to fix.
+- Pre-existing test failures in other files are expected. Only typecheck matters for your batch.
+```
+
+</agent-prompt-template>
+
+Fire ALL batches simultaneously. Wait for all to complete.
 
 ---
 
 ## PHASE 5: FINAL VERIFICATION
 
-**Mark final as in_progress.**
+After ALL agents complete:
 
-### 5.1: Full Test Suite
 ```bash
-bun test
+bun run typecheck   # must pass
+bun test            # note any NEW failures vs pre-existing
+bun run build       # must pass
 ```
 
-### 5.2: Full Typecheck
-```bash
-bun run typecheck
-```
-
-### 5.3: Full Build
-```bash
-bun run build
-```
-
-### 5.4: Summary Report
+Produce summary:
 
 ```markdown
 ## Dead Code Removal Complete
 
 ### Removed
-| # | Symbol | File | Type | Commit |
-|---|--------|------|------|--------|

+- File path → only that file
+- Directory → only that directory
+- Symbol name → only that symbol
+- `all` or empty → full project scan (default)
 
 ## ABORT CONDITIONS
 
-**STOP and report to user if:**
-- 3 consecutive removals cause test failures

-feature branches (your work)
-```
-
-### Rules (MANDATORY)
-
-| Rule | Description |
-|------|-------------|
-| **ALL PRs → `dev`** | Every pull request MUST target the `dev` branch |
-| **NEVER PR → `master`** | PRs to `master` are **automatically rejected** by CI |

-### Why This Matters
-
-- `master` = production/published npm package
-- `dev` = integration branch where features are merged and tested

-> **THIS SECTION MUST NEVER BE REMOVED OR MODIFIED**
-
-### This is an OpenCode Plugin
-
-Oh-My-OpenCode is a **plugin for OpenCode**. You will frequently need to examine OpenCode's source code to:
-- Understand plugin APIs and hooks
-- Debug integration issues
-- Implement features that interact with OpenCode internals
-- Answer questions about how OpenCode works
-
-### How to Access OpenCode Source Code
-
-**When you need to examine OpenCode source:**
-
-1. **Clone to system temp directory:**
-   ```bash
-   git clone https://github.com/sst/opencode /tmp/opencode-source
-   ```
-
-2. **Explore the codebase** from there (do NOT clone into the project directory)
-
-3. **Clean up** when done (optional, temp dirs are ephemeral)
-
-### Librarian Agent: YOUR PRIMARY TOOL for Plugin Work
-
-**CRITICAL**: When working on plugin-related tasks or answering plugin questions:
-
-| Scenario | Action |
-|----------|--------|
-| Implementing new hooks | Fire `librarian` to search OpenCode hook implementations |
-| Adding new tools | Fire `librarian` to find OpenCode tool patterns |
-| Understanding SDK behavior | Fire `librarian` to examine OpenCode SDK source |
-| Debugging plugin issues | Fire `librarian` to find relevant OpenCode internals |
-| Answering "how does OpenCode do X?" | Fire `librarian` FIRST |
-
-**DO NOT guess or hallucinate about OpenCode internals.** Always verify by examining actual source code via `librarian` or direct clone.

-## TDD (Test-Driven Development)
+## MULTI-LEVEL CONFIG
 
-**MANDATORY.** RED-GREEN-REFACTOR:
-1. **RED**: Write test → `bun test` → FAIL
-2. **GREEN**: Implement minimum → PASS
-3. **REFACTOR**: Clean up → stay GREEN
+```
+Project (.opencode/oh-my-opencode.jsonc)  →  User (~/.config/opencode/oh-my-opencode.jsonc)  →  Defaults
+```
 
-**Rules:**
-- NEVER write implementation before test
-- NEVER delete failing tests - fix the code
-- Test file: `*.test.ts` alongside source (176 test files)
-- BDD comments: `//#given`, `//#when`, `//#then`
+Fields: agents (14 overridable), categories (8 built-in + custom), disabled_* arrays, 19 feature-specific configs.
+
+## THREE-TIER MCP SYSTEM
+
+| Tier | Source | Mechanism |
+|------|--------|-----------|
+| Built-in | `src/mcp/` | 3 remote HTTP: websearch (Exa/Tavily), context7, grep_app |
+| Claude Code | `.mcp.json` | `${VAR}` env expansion via claude-code-mcp-loader |
+| Skill-embedded | SKILL.md YAML | Managed by SkillMcpManager (stdio + HTTP) |
 
 ## CONVENTIONS
 
-- **Package manager**: Bun only (`bun run`, `bun build`, `bunx`)
-- **Types**: bun-types (NEVER @types/node)
-- **Build**: `bun build` (ESM) + `tsc --emitDeclarationOnly`
-- **Exports**: Barrel pattern via index.ts
-- **Naming**: kebab-case dirs, `createXXXHook`/`createXXXTool` factories
-- **Testing**: BDD comments, 176 test files, 117k+ lines TypeScript
-- **Temperature**: 0.1 for code agents, max 0.3
-- **Modular architecture**: 200 LOC hard limit per file (prompt strings exempt)
+- **Test pattern**: Vitest, co-located `*.test.ts`, given/when/then style
+- **Factory pattern**: `createXXX()` for all tools, hooks, agents
+- **Hook tiers**: Session (19) → Tool-Guard (9) → Transform (4) → Continuation (7) → Skill (2)
+- **Agent modes**: `primary` (respects UI model) vs `subagent` (own fallback chain) vs `all`
+- **Model resolution**: 3-step: override → category-default → provider-fallback → system-default
+- **Config format**: JSONC with comments, Zod v4 validation, snake_case keys
 
 ## ANTI-PATTERNS
 
-| Category | Forbidden |
-|----------|-----------|
-| Package Manager | npm, yarn - Bun exclusively |
-| Types | @types/node - use bun-types |
-| File Ops | mkdir/touch/rm/cp/mv in code - use bash tool |
-| Publishing | Direct `bun publish` - GitHub Actions only |
-| Versioning | Local version bump - CI manages |
-| Type Safety | `as any`, `@ts-ignore`, `@ts-expect-error` |
-| Error Handling | Empty catch blocks |
-| Testing | Deleting failing tests, writing implementation before test |
-| Agent Calls | Sequential - use `task` parallel |
-| Hook Logic | Heavy PreToolUse - slows every call |
-| Commits | Giant (3+ files), separate test from impl |
-| Temperature | >0.3 for code agents |
-| Trust | Agent self-reports - ALWAYS verify |
-| Git | `git add -i`, `git rebase -i` (no interactive input) |
-| Git | Skip hooks (--no-verify), force push without request |
-| Bash | `sleep N` - use conditional waits |
-| Bash | `cd dir && cmd` - use workdir parameter |
-| Files | Catch-all utils.ts/helpers.ts - name by purpose |
-

-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**: 21 schema component files in `src/config/schema/`
-- **JSONC support**: Comments, trailing commas
-- **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)
+- Logger writes to `/tmp/oh-my-opencode.log` — check there for debugging
+- Background tasks: 5 concurrent per model/provider (configurable)
+- Plugin load timeout: 10s for Claude Code plugins
+- Model fallback priority: Claude > OpenAI > Gemini > Copilot > OpenCode Zen > Z.ai > Kimi
+- Config migration runs automatically on legacy keys (agent names, hook names, model versions)

+Root source directory. Entry point `index.ts` orchestrates 4-step initialization: config → managers → tools → hooks → plugin interface.
+
+## KEY FILES
+
+| File | Purpose |
+|------|---------|
+| `index.ts` | Plugin entry, exports `OhMyOpenCodePlugin` |
+| `plugin-config.ts` | JSONC parse, multi-level merge (user → project → defaults), Zod validation |
+| `create-managers.ts` | TmuxSessionManager, BackgroundManager, SkillMcpManager, ConfigHandler |
+| `create-tools.ts` | SkillContext + AvailableCategories + ToolRegistry |
+| `create-hooks.ts` | 3-tier hook composition: Core(32) + Continuation(7) + Skill(2) |
+| `plugin-interface.ts` | Assembles 8 OpenCode hook handlers into PluginInterface |

-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

-
-**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`):

-
-**Skill Hooks** (`create-skill-hooks.ts`):
-- 2 hooks: category-skill-reminder, auto-slash-command

-
-| 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 |

-## HOW TO ADD
+## FACTORY PATTERN
 
-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`
+```typescript
+const createXXXAgent: AgentFactory = (model: string) => ({
+  instructions: "...",
+  model,
+  temperature: 0.1,
+  // ...config
+})
+createXXXAgent.mode = "subagent" // or "primary" or "all"
+```
 
-## KEY PATTERNS
+Model resolution: `AGENT_MODEL_REQUIREMENTS` in `shared/model-requirements.ts` defines fallback chains per agent.
 
-- **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
+## MODES
 
-## ANTI-PATTERNS
-
-- **Trust agent self-reports**: NEVER — always verify outputs
-- **High temperature**: Don't use >0.3 for code agents
-- **Sequential calls**: Use `task` with `run_in_background` for exploration
-- **Prometheus writing code**: Planner only — never implements
+- **primary**: Respects UI-selected model, uses fallback chain
+- **subagent**: Uses own fallback chain, ignores UI selection
+- **all**: Available in both contexts (Sisyphus-Junior)

-**Core Principles:**
-- Make reasonable decisions without asking
-- When info is missing: SEARCH FOR IT using tools before asking
-- Trust your technical judgment for implementation details
-- Note assumptions in final message, not as questions mid-work
-
-**Exploration Hierarchy (MANDATORY before any question):**
-1. **Direct tools**: \`gh pr list\`, \`git log\`, \`grep\`, \`rg\`, file reads
-2. **Explore agents**: Fire 2-3 parallel background searches
-3. **Librarian agents**: Check docs, GitHub, external sources
-4. **Context inference**: Use surrounding context to make educated guess
-5. **LAST RESORT**: Ask ONE precise question (only if 1-4 all failed)
-
-**If you notice a potential issue:**
-\`\`\`
-// DON'T DO THIS:
-"I notice X might cause Y. Should I proceed?"
-
-// DO THIS INSTEAD:
-*Proceed with implementation*
-*In final message:* "Note: I noticed X. I handled it by doing Z to avoid Y."
-\`\`\`
-
-**Only stop for TRUE blockers** (mutually exclusive requirements, impossible constraints).
+Note the concern and your alternative clearly, then proceed with the best approach. If the risk is major, flag it before implementing.

+- "Explored the repo — auth middleware lives in \`src/middleware/\`. Now patching the handler."
+- "All tests passing. Just cleaning up the 2 lint errors from my changes."
+- "Found the pattern in \`utils/parser.ts\`. Applying the same approach to the new module."

-- Track: files modified, changes made, verifications completed, next steps
-- Do not lose track of the original request across many tool calls
-- If context feels overwhelming, pause and create a checkpoint summary
+### Before Writing Code (MANDATORY)
 
-## Code Quality Standards
+1. SEARCH existing codebase for similar patterns/styles
+2. Match naming, indentation, import styles, error handling conventions
+3. Default to ASCII. Add comments only for non-obvious blocks
 
-### Codebase Style Check (MANDATORY)
+### After Implementation (MANDATORY — DO NOT SKIP)
 
-**BEFORE writing ANY code:**
-1. SEARCH the existing codebase to find similar patterns/styles
-2. Your code MUST match the project's existing conventions
-3. Write READABLE code - no clever tricks
-4. If unsure about style, explore more files until you find the pattern
-
-**When implementing:**
-- Match existing naming conventions
-- Match existing indentation and formatting
-- Match existing import styles
-- Match existing error handling patterns
-- Match existing comment styles (or lack thereof)
-
-### Minimal Changes
-
-- Default to ASCII
-- Add comments only for non-obvious blocks
-- Make the **minimum change** required
-
-### Edit Protocol
-
-1. Always read the file first
-2. Include sufficient context for unique matching
-3. Use \`apply_patch\` for edits
-4. Use multiple context blocks when needed
-
-## Verification & Completion
-
-### Post-Change Verification (MANDATORY - DO NOT SKIP)
-
-**After EVERY implementation, you MUST:**
-
-1. **Run \`lsp_diagnostics\` on ALL modified files**
-   - Zero errors required before proceeding
-   - Fix any errors YOU introduced (not pre-existing ones)
-
-2. **Find and run related tests**
-   - Search for test files: \`*.test.ts\`, \`*.spec.ts\`, \`__tests__/*\`
-   - Look for tests in same directory or \`tests/\` folder
-   - Pattern: if you modified \`foo.ts\`, look for \`foo.test.ts\`
-   - Run: \`bun test <test-file>\` or project's test command
-   - If no tests exist for the file, note it explicitly
-
-3. **Run typecheck if TypeScript project**
-   - \`bun run typecheck\` or \`tsc --noEmit\`
-
-4. **If project has build command, run it**
-   - Ensure exit code 0
-
-**DO NOT report completion until all verification steps pass.**
-
-### Evidence Requirements
+1. **\`lsp_diagnostics\`** on ALL modified files — zero errors required
+2. **Run related tests** — pattern: modified \`foo.ts\` → look for \`foo.test.ts\`
+3. **Run typecheck** if TypeScript project
+4. **Run build** if applicable — exit code 0 required
+5. **Tell user** what you verified and the results — keep it clear and helpful
 
 | Action | Required Evidence |
 |--------|-------------------|
 | File edit | \`lsp_diagnostics\` clean |
-| Build command | Exit code 0 |
-| Test run | Pass (or pre-existing failures noted) |

 **NO EVIDENCE = NOT COMPLETE.**
 
+## Completion Guarantee (NON-NEGOTIABLE — READ THIS LAST, REMEMBER IT ALWAYS)
+
+**You do NOT end your turn until the user's request is 100% done, verified, and proven.**
+
+This means:
+1. **Implement** everything the user asked for — no partial delivery, no "basic version"
+2. **Verify** with real tools: \`lsp_diagnostics\`, build, tests — not "it should work"
+3. **Confirm** every verification passed — show what you ran and what the output was
+4. **Re-read** the original request — did you miss anything? Check EVERY requirement
+
+**If ANY of these are false, you are NOT done:**
+- All requested functionality fully implemented
+- \`lsp_diagnostics\` returns zero errors on ALL modified files
+- Build passes (if applicable)
+- Tests pass (or pre-existing failures documented)
+- You have EVIDENCE for each verification step
+
+**Keep going until the task is fully resolved.** Persist even when tool calls fail. Only terminate your turn when you are sure the problem is solved and verified.
+
+**When you think you're done: Re-read the request. Run verification ONE MORE TIME. Then report.**
+
 ## Failure Recovery
 
-### Fix Protocol
+1. Fix root causes, not symptoms. Re-verify after EVERY attempt.
+2. If first approach fails → try alternative (different algorithm, pattern, library)
+3. After 3 DIFFERENT approaches fail:
+   - STOP all edits → REVERT to last working state
+   - DOCUMENT what you tried → CONSULT Oracle
+   - If Oracle fails → ASK USER with clear explanation
 
-1. Fix root causes, not symptoms
-2. Re-verify after EVERY fix attempt
-3. Never shotgun debug
-
-### After Failure (AUTONOMOUS RECOVERY)
-
-1. **Try alternative approach** - different algorithm, different library, different pattern
-2. **Decompose** - break into smaller, independently solvable steps
-3. **Challenge assumptions** - what if your initial interpretation was wrong?
-4. **Explore more** - fire explore/librarian agents for similar problems solved elsewhere
-
-### After 3 DIFFERENT Approaches Fail
-
-1. **STOP** all edits
-2. **REVERT** to last working state
-3. **DOCUMENT** what you tried (all 3 approaches)
-4. **CONSULT** Oracle with full context
-5. If Oracle cannot help, **ASK USER** with clear explanation of attempts
-
-**Never**: Leave code broken, delete failing tests, continue hoping
-

-
-\`\`\`
-Scenario: [Descriptive name — what user action/flow is being verified]
-  Tool: [Playwright / interactive_bash / Bash]
-  Preconditions: [What must be true before this scenario runs]
-  Steps:
-    1. [Exact action with specific selector/command/endpoint]
-    2. [Next action with expected intermediate state]
-    3. [Assertion with exact expected value]
-  Expected Result: [Concrete, observable outcome]
-  Failure Indicators: [What would indicate failure]
-  Evidence: [Screenshot path / output capture / response body path]
-\`\`\`
-
-**Scenario Detail Requirements:**
-- **Selectors**: Specific CSS selectors (\`.login-button\`, not "the login button")
-- **Data**: Concrete test data (\`"test@example.com"\`, not \`"[email]"\`)
-- **Assertions**: Exact values (\`text contains "Welcome back"\`, not "verify it works")
-- **Timing**: Include wait conditions where relevant (\`Wait for .dashboard (timeout: 10s)\`)
-- **Negative Scenarios**: At least ONE failure/error scenario per feature
-- **Evidence Paths**: Specific file paths (\`.sisyphus/evidence/task-N-scenario-name.png\`)
-
-**Anti-patterns (NEVER write scenarios like this):**
-- ❌ "Verify the login page works correctly"
-- ❌ "Check that the API returns the right data"
-- ❌ "Test the form validation"
-- ❌ "User opens browser and confirms..."
-
-**Write scenarios like this instead:**
-- ✅ \`Navigate to /login → Fill input[name="email"] with "test@example.com" → Fill input[name="password"] with "Pass123!" → Click button[type="submit"] → Wait for /dashboard → Assert h1 contains "Welcome"\`
-- ✅ \`POST /api/users {"name":"Test","email":"new@test.com"} → Assert status 201 → Assert response.id is UUID → GET /api/users/{id} → Assert name equals "Test"\`
-- ✅ \`Run ./cli --config test.yaml → Wait for "Loaded" in stdout → Send "q" → Assert exit code 0 → Assert stdout contains "Goodbye"\`
-
-**Evidence Requirements:**
-- Screenshots: \`.sisyphus/evidence/\` for all UI verifications
-- Terminal output: Captured for CLI/TUI verifications
-- Response bodies: Saved for API verifications
-- All evidence referenced by specific file path in acceptance criteria

-Task NOT complete without evidence:
+## Progress Updates
+
+**Report progress proactively — the user should always know what you're doing and why.**
+
+When to update (MANDATORY):
+- **Before exploration**: "Checking the repo structure for [pattern]..."
+- **After discovery**: "Found the config in \`src/config/\`. The pattern uses factory functions."
+- **Before large edits**: "About to modify [files] — [what and why]."
+- **After edits**: "Updated [file] — [what changed]. Running verification."
+- **On blockers**: "Hit a snag with [issue] — trying [alternative] instead."
+
+Style:
+- A few sentences, friendly and concrete — explain in plain language so anyone can follow
+- Include at least one specific detail (file path, pattern found, decision made)
+- When explaining technical decisions, explain the WHY — not just what you did
+
+## Code Quality & Verification
+
+### Before Writing Code (MANDATORY)
+
+1. SEARCH existing codebase for similar patterns/styles
+2. Match naming, indentation, import styles, error handling conventions
+3. Default to ASCII. Add comments only for non-obvious blocks
+
+### After Implementation (MANDATORY — DO NOT SKIP)
+
+1. **\`lsp_diagnostics\`** on ALL modified files — zero errors required
+2. **Run related tests** — pattern: modified \`foo.ts\` → look for \`foo.test.ts\`
+3. **Run typecheck** if TypeScript project
+4. **Run build** if applicable — exit code 0 required
+5. **Tell user** what you verified and the results — keep it clear and helpful
+

-- Start immediately. No acknowledgments ("I'll...", "Let me...").
-- Match user's communication style.
-- Dense > verbose.
-- Use structured output (bullets, tables) over prose.
-</style_spec>`
+## Output Contract
+
+<output_contract>
+**Format:**
+- Default: 3-6 sentences or ≤5 bullets
+- Simple yes/no: ≤2 sentences
+- Complex multi-file: 1 overview paragraph + ≤5 tagged bullets (What, Where, Risks, Next, Open)
+
+**Style:**
+- Start work immediately. Skip empty preambles ("I'm on it", "Let me...") — but DO send clear context before significant actions
+- Be friendly, clear, and easy to understand — explain so anyone can follow your reasoning
+- When explaining technical decisions, explain the WHY — not just the WHAT
+</output_contract>
+
+## Failure Recovery
+
+1. Fix root causes, not symptoms. Re-verify after EVERY attempt.
+2. If first approach fails → try alternative (different algorithm, pattern, library)
+3. After 3 DIFFERENT approaches fail → STOP and report what you tried clearly`

+Commander.js CLI with 5 commands. Entry: `index.ts` → `runCli()` in `cli-program.ts`.
 
 ## COMMANDS
 
 | 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 |
+| `install` | Interactive/non-interactive setup | Provider selection → config gen → plugin registration |
+| `run <message>` | Non-interactive session launcher | Agent resolution (flag → env → config → Sisyphus) |
+| `doctor` | 4-category health checks | System, Config, Tools, Models |
+| `get-local-version` | Version detection | Installed vs npm latest |
+| `mcp-oauth` | OAuth token management | login (PKCE), logout, status |
 
-## DOCTOR CHECK CATEGORIES
+## STRUCTURE
 
-| Category | Checks |
-|----------|--------|
-| installation | opencode, plugin |
-| configuration | config validity, Zod, model-resolution (6 sub-checks) |
-| authentication | anthropic, openai, google |
-| dependencies | ast-grep, comment-checker, gh-cli |
-| tools | LSP, MCP, MCP-OAuth |
-| updates | version comparison |

-## HOW TO ADD CHECK
+## MODEL FALLBACK SYSTEM
 
-1. Create `src/cli/doctor/checks/my-check.ts`
-2. Export `getXXXCheckDefinition()` returning `CheckDefinition`
-3. Add to `getAllCheckDefinitions()` in `checks/index.ts`
+Priority: Claude > OpenAI > Gemini > Copilot > OpenCode Zen > Z.ai > Kimi > glm-4.7-free
 
-## ANTI-PATTERNS
+Agent-specific: librarian→ZAI, explore→Haiku/nano, hephaestus→requires OpenAI/Copilot
 
-- **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
+## DOCTOR CHECKS
+
+| Category | Validates |
+|----------|-----------|
+| **System** | Binary found, version >=1.0.150, plugin registered, version match |
+| **Config** | JSONC validity, Zod schema, model override syntax |
+| **Tools** | AST-Grep, comment-checker, LSP servers, GH CLI, MCP servers |
+| **Models** | Cache exists, model resolution, agent/category overrides, availability |
+
+## HOW TO ADD A DOCTOR CHECK
+
+1. Create `src/cli/doctor/checks/{name}.ts`
+2. Export check function matching `DoctorCheck` interface
+3. Register in `checks/index.ts`

-**Background Agent Lifecycle:**
-Task creation → Queue → Concurrency check → Execute → Monitor/Poll → Notification → Cleanup
+## KEY MODULES
 
-**Skill Loading Pipeline (4-scope priority):**
-opencode-project (`.opencode/skills/`) > opencode (`~/.config/opencode/skills/`) > project (`.claude/skills/`) > user (`~/.claude/skills/`)
+### background-agent (49 files, ~10k LOC)
 
-**Claude Code Compatibility Layer:**
-5 loaders: agent-loader, command-loader, mcp-loader, plugin-loader, session-state
+Core orchestration engine. `BackgroundManager` manages task lifecycle:
+- States: pending → running → completed/error/cancelled/interrupt
+- Concurrency: per-model/provider limits via `ConcurrencyManager` (FIFO queue)
+- Polling: 3s interval, completion via idle events + stability detection (10s unchanged)
+- spawner/: 8 focused files composing via `SpawnerContext` interface
 
-**SKILL.md Format:**
-```yaml
----
-name: my-skill
-description: "..."
-model: "claude-opus-4-6"    # optional
-agent: "sisyphus"           # optional
-mcp:                        # optional embedded MCPs
-  server-name:
-    type: http
-    url: https://...
----
-# Skill instruction content
-```
+### opencode-skill-loader (25 files, ~3.2k LOC)
 
-## HOW TO ADD
+4-scope skill discovery (project > opencode > user > global):
+- YAML frontmatter parsing from SKILL.md files
+- Skill merger with priority deduplication
+- Template resolution with variable substitution
+- Provider gating for model-specific skills
 
-1. Create directory under `src/features/`
-2. Add `index.ts`, `types.ts`, `constants.ts` as needed
-3. Export from `index.ts` following barrel pattern
-4. Register in main plugin if plugin-level feature
+### tmux-subagent (27 files, ~3.6k LOC)
 
-## CHILD DOCUMENTATION
+State-first tmux integration:
+- `TmuxSessionManager`: pane lifecycle, grid planning
+- Spawn action decider + target finder
+- Polling manager for session health
+- Event handlers for pane creation/destruction
 
-- See `claude-tasks/AGENTS.md` for task schema and storage details
