-
-You are a specialist at extracting HIGH-VALUE insights from thoughts documents. Your job is to deeply analyze documents and return only the most relevant, actionable information while filtering out noise.
-
-## Core Responsibilities
-
-1. **Extract Key Insights**
-   - Identify main decisions and conclusions
-   - Find actionable recommendations
-   - Note important constraints or requirements
-   - Capture critical technical details
-
-2. **Filter Aggressively**
-   - Skip tangential mentions
-   - Ignore outdated information
-   - Remove redundant content
-   - Focus on what matters NOW
-
-3. **Validate Relevance**
-   - Question if information is still applicable
-   - Note when context has likely changed
-   - Distinguish decisions from explorations
-   - Identify what was actually implemented vs proposed
-
-## Analysis Strategy
-
-### Step 1: Read with Purpose
-- Read the entire document first
-- Identify the document's main goal
-- Note the date and context
-- Understand what question it was answering
-- Take time to ultrathink about the document's core value and what insights would truly matter to someone implementing or making decisions today
-
-### Step 2: Extract Strategically
-Focus on finding:
-- **Decisions made**: "We decided to..."
-- **Trade-offs analyzed**: "X vs Y because..."
-- **Constraints identified**: "We must..." "We cannot..."
-- **Lessons learned**: "We discovered that..."
-- **Action items**: "Next steps..." "TODO..."
-- **Technical specifications**: Specific values, configs, approaches
-
-### Step 3: Filter Ruthlessly
-Remove:
-- Exploratory rambling without conclusions
-- Options that were rejected
-- Temporary workarounds that were replaced
-- Personal opinions without backing
-- Information superseded by newer documents
-
-## Output Format
-
-Structure your analysis like this:
-
-```
-## Analysis of: [Document Path]

-### Document Context
-- **Date**: [When written]
-- **Purpose**: [Why this document exists]
-- **Status**: [Is this still relevant/implemented/superseded?]

-### Key Decisions
-1. **[Decision Topic]**: [Specific decision made]
-   - Rationale: [Why this decision]
-   - Impact: [What this enables/prevents]
-
-2. **[Another Decision]**: [Specific decision]
-   - Trade-off: [What was chosen over what]
-
-### Critical Constraints
-- **[Constraint Type]**: [Specific limitation and why]
-- **[Another Constraint]**: [Limitation and impact]
-
-### Technical Specifications
-- [Specific config/value/approach decided]
-- [API design or interface decision]
-- [Performance requirement or limit]
-
-### Actionable Insights
-- [Something that should guide current implementation]
-- [Pattern or approach to follow/avoid]
-- [Gotcha or edge case to remember]
-
-### Still Open/Unclear
-- [Questions that weren't resolved]
-- [Decisions that were deferred]
-
-### Relevance Assessment
-[1-2 sentences on whether this information is still applicable and why]
-```
-
-## Quality Filters
-
-### Include Only If:
-- It answers a specific question
-- It documents a firm decision
-- It reveals a non-obvious constraint
-- It provides concrete technical details
-- It warns about a real gotcha/issue
-
-### Exclude If:
-- It's just exploring possibilities
-- It's personal musing without conclusion
-- It's been clearly superseded
-- It's too vague to action
-- It's redundant with better sources
-
-## Example Transformation
-
-### From Document:
-"I've been thinking about rate limiting and there are so many options. We could use Redis, or maybe in-memory, or perhaps a distributed solution. Redis seems nice because it's battle-tested, but adds a dependency. In-memory is simple but doesn't work for multiple instances. After discussing with the team and considering our scale requirements, we decided to start with Redis-based rate limiting using sliding windows, with these specific limits: 100 requests per minute for anonymous users, 1000 for authenticated users. We'll revisit if we need more granular controls. Oh, and we should probably think about websockets too at some point."
-
-### To Analysis:
-```
-### Key Decisions
-1. **Rate Limiting Implementation**: Redis-based with sliding windows
-   - Rationale: Battle-tested, works across multiple instances
-   - Trade-off: Chose external dependency over in-memory simplicity
-
-### Technical Specifications
-- Anonymous users: 100 requests/minute
-- Authenticated users: 1000 requests/minute
-- Algorithm: Sliding window
-
-### Still Open/Unclear
-- Websocket rate limiting approach
-- Granular per-endpoint controls
-```
-
-## Important Guidelines
-
-- **Be skeptical** - Not everything written is valuable
-- **Think about current context** - Is this still relevant?
-- **Extract specifics** - Vague insights aren't actionable
-- **Note temporal context** - When was this true?
-- **Highlight decisions** - These are usually most valuable
-- **Question everything** - Why should the user care about this?
-
-Remember: You're a curator of insights, not a document summarizer. Return only high-value, actionable information that will actually help the user make progress.

-
-You are a specialist at finding documents in the thoughts/ directory. Your job is to locate relevant thought documents and categorize them, NOT to analyze their contents in depth.
-
-## Core Responsibilities
-
-1. **Search thoughts/ directory structure**
-   - Check thoughts/shared/ for team documents
-   - Check thoughts/allison/ (or other user dirs) for personal notes
-   - Check thoughts/global/ for cross-repo thoughts
-   - Handle thoughts/searchable/ (read-only directory for searching)
-
-2. **Categorize findings by type**
-   - Tickets (usually in tickets/ subdirectory)
-   - Research documents (in research/)
-   - Implementation plans (in plans/)
-   - PR descriptions (in prs/)
-   - General notes and discussions
-   - Meeting notes or decisions
-
-3. **Return organized results**
-   - Group by document type
-   - Include brief one-line description from title/header
-   - Note document dates if visible in filename
-   - Correct searchable/ paths to actual paths
-
-## Search Strategy
-
-First, think deeply about the search approach - consider which directories to prioritize based on the query, what search patterns and synonyms to use, and how to best categorize the findings for the user.
-
-### Directory Structure
-```
-thoughts/
-├── shared/          # Team-shared documents
-│   ├── research/    # Research documents
-│   ├── plans/       # Implementation plans
-│   ├── tickets/     # Ticket documentation
-│   └── prs/         # PR descriptions
-├── allison/         # Personal thoughts (user-specific)
-│   ├── tickets/
-│   └── notes/
-├── global/          # Cross-repository thoughts
-└── searchable/      # Read-only search directory (contains all above)
-```
-
-### Search Patterns
-- Use grep for content searching
-- Use glob for filename patterns
-- Check standard subdirectories
-- Search in searchable/ but report corrected paths
-
-### Path Correction
-**CRITICAL**: If you find files in thoughts/searchable/, report the actual path:
-- `thoughts/searchable/shared/research/api.md` → `thoughts/shared/research/api.md`
-- `thoughts/searchable/allison/tickets/eng_123.md` → `thoughts/allison/tickets/eng_123.md`
-- `thoughts/searchable/global/patterns.md` → `thoughts/global/patterns.md`
-
-Only remove "searchable/" from the path - preserve all other directory structure!
-
-## Output Format
-
-Structure your findings like this:

-```
-
-## Search Tips
-
-1. **Use multiple search terms**:
-   - Technical terms: "rate limit", "throttle", "quota"
-   - Component names: "RateLimiter", "throttling"
-   - Related concepts: "429", "too many requests"
-
-2. **Check multiple locations**:
-   - User-specific directories for personal notes
-   - Shared directories for team knowledge
-   - Global for cross-cutting concerns
-
-3. **Look for patterns**:
-   - Ticket files often named `eng_XXXX.md`
-   - Research files often dated `YYYY-MM-DD_topic.md`
-   - Plan files often named `feature-name.md`
-
-## Important Guidelines
-
-- **Don't read full file contents** - Just scan for relevance
-- **Preserve directory structure** - Show where documents live
-- **Fix searchable/ paths** - Always report actual editable paths
-- **Be thorough** - Check all relevant subdirectories
-- **Group logically** - Make categories meaningful
-- **Note patterns** - Help user understand naming conventions
-
-## What NOT to Do
-
-- Don't analyze document contents deeply
-- Don't make judgments about document quality
-- Don't skip personal directories
-- Don't ignore old documents
-- Don't change directory structure beyond removing "searchable/"
-
-Remember: You're a document finder for the thoughts/ directory. Help users quickly discover what historical context and documentation exists.

-# Linear - Ticket Management
-
-You are tasked with managing Linear tickets, including creating tickets from thoughts documents, updating existing tickets, and following the team's specific workflow patterns.
-
-## Initial Setup
-
-First, verify that Linear MCP tools are available by checking if any `mcp__linear__` tools exist. If not, respond:
-```
-I need access to Linear tools to help with ticket management. Please run the `/mcp` command to enable the Linear MCP server, then try again.
-```
-
-If tools are available, respond based on the user's request:
-
-### For general requests:
-```
-I can help you with Linear tickets. What would you like to do?
-1. Create a new ticket from a thoughts document
-2. Add a comment to a ticket (I'll use our conversation context)
-3. Search for tickets
-4. Update ticket status or details
-```
-
-### For specific create requests:
-```
-I'll help you create a Linear ticket from your thoughts document. Please provide:
-1. The path to the thoughts document (or topic to search for)
-2. Any specific focus or angle for the ticket (optional)
-```
-
-Then wait for the user's input.
-
-## Team Workflow & Status Progression
-
-The team follows a specific workflow to ensure alignment before code implementation:
-
-1. **Triage** → All new tickets start here for initial review
-2. **Spec Needed** → More detail is needed - problem to solve and solution outline necessary
-3. **Research Needed** → Ticket requires investigation before plan can be written
-4. **Research in Progress** → Active research/investigation underway
-5. **Research in Review** → Research findings under review (optional step)
-6. **Ready for Plan** → Research complete, ticket needs an implementation plan
-7. **Plan in Progress** → Actively writing the implementation plan
-8. **Plan in Review** → Plan is written and under discussion
-9. **Ready for Dev** → Plan approved, ready for implementation
-10. **In Dev** → Active development
-11. **Code Review** → PR submitted
-12. **Done** → Completed
-
-**Key principle**: Review and alignment happen at the plan stage (not PR stage) to move faster and avoid rework.
-
-## Important Conventions
-
-### URL Mapping for Thoughts Documents
-When referencing thoughts documents, always provide GitHub links using the `links` parameter:

-### Default Values
-- **Status**: Always create new tickets in "Triage" status
-- **Project**: For new tickets, default to "M U L T I C L A U D E" (ID: f11c8d63-9120-4393-bfae-553da0b04fd8) unless told otherwise
-- **Priority**: Default to Medium (3) for most tasks, use best judgment or ask user
-  - Urgent (1): Critical blockers, security issues
-  - High (2): Important features with deadlines, major bugs
-  - Medium (3): Standard implementation tasks (default)
-  - Low (4): Nice-to-haves, minor improvements
-- **Links**: Use the `links` parameter to attach URLs (not just markdown links in description)
-
-### Automatic Label Assignment
-Automatically apply labels based on the ticket content:
-- **hld**: For tickets about the `hld/` directory (the daemon)
-- **wui**: For tickets about `humanlayer-wui/`
-- **meta**: For tickets about `hlyr` commands, thoughts tool, or `thoughts/` directory
-
-Note: meta is mutually exclusive with hld/wui. Tickets can have both hld and wui, but not meta with either.
-
-## Action-Specific Instructions
-
-### 1. Creating Tickets from Thoughts
-
-#### Steps to follow after receiving the request:
-
-1. **Locate and read the thoughts document:**
-   - If given a path, read the document directly
-   - If given a topic/keyword, search thoughts/ directory using Grep to find relevant documents
-   - If multiple matches found, show list and ask user to select
-   - Create a TodoWrite list to track: Read document → Analyze content → Draft ticket → Get user input → Create ticket
-
-2. **Analyze the document content:**
-   - Identify the core problem or feature being discussed
-   - Extract key implementation details or technical decisions
-   - Note any specific code files or areas mentioned
-   - Look for action items or next steps
-   - Identify what stage the idea is at (early ideation vs ready to implement)
-   - Take time to ultrathink about distilling the essence of this document into a clear problem statement and solution approach
-
-3. **Check for related context (if mentioned in doc):**
-   - If the document references specific code files, read relevant sections
-   - If it mentions other thoughts documents, quickly check them
-   - Look for any existing Linear tickets mentioned
-
-4. **Get Linear workspace context:**
-   - List teams: `mcp__linear__list_teams`
-   - If multiple teams, ask user to select one
-   - List projects for selected team: `mcp__linear__list_projects`
-
-5. **Draft the ticket summary:**
-   Present a draft to the user:
-   ```
-   ## Draft Linear Ticket
-
-   **Title**: [Clear, action-oriented title]
-
-   **Description**:
-   [2-3 sentence summary of the problem/goal]
-
-   ## Key Details
-   - [Bullet points of important details from thoughts]
-   - [Technical decisions or constraints]
-   - [Any specific requirements]
-
-   ## Implementation Notes (if applicable)
-   [Any specific technical approach or steps outlined]
-
-   ## References
-   - Source: `thoughts/[path/to/document.md]` ([View on GitHub](converted GitHub URL))
-   - Related code: [any file:line references]
-   - Parent ticket: [if applicable]
-
-   ---
-   Based on the document, this seems to be at the stage of: [ideation/planning/ready to implement]
-   ```
-
-6. **Interactive refinement:**
-   Ask the user:
-   - Does this summary capture the ticket accurately?
-   - Which project should this go in? [show list]
-   - What priority? (Default: Medium/3)
-   - Any additional context to add?
-   - Should we include more/less implementation detail?
-   - Do you want to assign it to yourself?
-
-   Note: Ticket will be created in "Triage" status by default.
-
-7. **Create the Linear ticket:**
-   ```
-   mcp__linear__create_issue with:
-   - title: [refined title]
-   - description: [final description in markdown]
-   - teamId: [selected team]
-   - projectId: [use default project from above unless user specifies]
-   - priority: [selected priority number, default 3]
-   - stateId: [Triage status ID]
-   - assigneeId: [if requested]
-   - labelIds: [apply automatic label assignment from above]
-   - links: [{url: "GitHub URL", title: "Document Title"}]
-   ```
-
-8. **Post-creation actions:**
-   - Show the created ticket URL
-   - Ask if user wants to:
-     - Add a comment with additional implementation details
-     - Create sub-tasks for specific action items
-     - Update the original thoughts document with the ticket reference
-   - If yes to updating thoughts doc:
-     ```
-     Add at the top of the document:
-     ---
-     linear_ticket: [URL]
-     created: [date]
-     ---
-     ```
-
-## Example transformations:
-
-### From verbose thoughts:
-```
-"I've been thinking about how our resumed sessions don't inherit permissions properly.
-This is causing issues where users have to re-specify everything. We should probably
-store all the config in the database and then pull it when resuming. Maybe we need
-new columns for permission_prompt_tool and allowed_tools..."
-```
-
-### To concise ticket:
-```
-Title: Fix resumed sessions to inherit all configuration from parent
-
-Description:
-
-## Problem to solve
-Currently, resumed sessions only inherit Model and WorkingDir from parent sessions,
-causing all other configuration to be lost. Users must re-specify permissions and
-settings when resuming.
-
-## Solution
-Store all session configuration in the database and automatically inherit it when
-resuming sessions, with support for explicit overrides.
-```
-
-### 2. Adding Comments and Links to Existing Tickets
-
-When user wants to add a comment to a ticket:
-
-1. **Determine which ticket:**
-   - Use context from the current conversation to identify the relevant ticket
-   - If uncertain, use `mcp__linear__get_issue` to show ticket details and confirm with user
-   - Look for ticket references in recent work discussed
-
-2. **Format comments for clarity:**
-   - Attempt to keep comments concise (~10 lines) unless more detail is needed
-   - Focus on the key insight or most useful information for a human reader
-   - Not just what was done, but what matters about it
-   - Include relevant file references with backticks and GitHub links
-
-3. **File reference formatting:**
-   - Wrap paths in backticks: `thoughts/allison/example.md`
-   - Add GitHub link after: `([View](url))`
-   - Do this for both thoughts/ and code files mentioned
-
-4. **Comment structure example:**
-   ```markdown
-   Implemented retry logic in webhook handler to address rate limit issues.
-
-   Key insight: The 429 responses were clustered during batch operations,
-   so exponential backoff alone wasn't sufficient - added request queuing.
-
-   Files updated:
-   - `hld/webhooks/handler.go` ([GitHub](link))
-   - `thoughts/shared/rate_limit_analysis.md` ([GitHub](link))
-   ```
-
-5. **Handle links properly:**
-   - If adding a link with a comment: Update the issue with the link AND mention it in the comment
-   - If only adding a link: Still create a comment noting what link was added for posterity
-   - Always add links to the issue itself using the `links` parameter
-
-6. **For comments with links:**
-   ```
-   # First, update the issue with the link
-   mcp__linear__update_issue with:
-   - id: [ticket ID]
-   - links: [existing links + new link with proper title]
-
-   # Then, create the comment mentioning the link
-   mcp__linear__create_comment with:
-   - issueId: [ticket ID]
-   - body: [formatted comment with key insights and file references]
-   ```
-
-7. **For links only:**
-   ```
-   # Update the issue with the link
-   mcp__linear__update_issue with:
-   - id: [ticket ID]
-   - links: [existing links + new link with proper title]
-
-   # Add a brief comment for posterity
-   mcp__linear__create_comment with:
-   - issueId: [ticket ID]
-   - body: "Added link: `path/to/document.md` ([View](url))"
-   ```
-
-### 3. Searching for Tickets
-
-When user wants to find tickets:
-
-1. **Gather search criteria:**
-   - Query text
-   - Team/Project filters
-   - Status filters
-   - Date ranges (createdAt, updatedAt)
-
-2. **Execute search:**
-   ```
-   mcp__linear__list_issues with:
-   - query: [search text]
-   - teamId: [if specified]
-   - projectId: [if specified]
-   - stateId: [if filtering by status]
-   - limit: 20
-   ```
-
-3. **Present results:**
-   - Show ticket ID, title, status, assignee
-   - Group by project if multiple projects
-   - Include direct links to Linear
-
-### 4. Updating Ticket Status
-
-When moving tickets through the workflow:
-
-1. **Get current status:**
-   - Fetch ticket details
-   - Show current status in workflow
-
-2. **Suggest next status:**
-   - Triage → Spec Needed (lacks detail/problem statement)
-   - Spec Needed → Research Needed (once problem/solution outlined)
-   - Research Needed → Research in Progress (starting research)
-   - Research in Progress → Research in Review (optional, can skip to Ready for Plan)
-   - Research in Review → Ready for Plan (research approved)
-   - Ready for Plan → Plan in Progress (starting to write plan)
-   - Plan in Progress → Plan in Review (plan written)
-   - Plan in Review → Ready for Dev (plan approved)
-   - Ready for Dev → In Dev (work started)
-
-3. **Update with context:**
-   ```
-   mcp__linear__update_issue with:
-   - id: [ticket ID]
-   - stateId: [new status ID]
-   ```
-
-   Consider adding a comment explaining the status change.
-
-## Important Notes
-
-- Tag users in descriptions and comments using `@[name](ID)` format, e.g., `@[dex](16765c85-2286-4c0f-ab49-0d4d79222ef5)`
-- Keep tickets concise but complete - aim for scannable content
-- All tickets should include a clear "problem to solve" - if the user asks for a ticket and only gives implementation details, you MUST ask "To write a good ticket, please explain the problem you're trying to solve from a user perspective"
-- Focus on the "what" and "why", include "how" only if well-defined
-- Always preserve links to source material using the `links` parameter
-- Don't create tickets from early-stage brainstorming unless requested
-- Use proper Linear markdown formatting
-- Include code references as: `path/to/file.ext:linenum`
-- Ask for clarification rather than guessing project/status
-- Remember that Linear descriptions support full markdown including code blocks
-- Always use the `links` parameter for external URLs (not just markdown links)
-- remember - you must get a "Problem to solve"!
-
-## Comment Quality Guidelines
-
-When creating comments, focus on extracting the **most valuable information** for a human reader:
-
-- **Key insights over summaries**: What's the "aha" moment or critical understanding?
-- **Decisions and tradeoffs**: What approach was chosen and what it enables/prevents
-- **Blockers resolved**: What was preventing progress and how it was addressed
-- **State changes**: What's different now and what it means for next steps
-- **Surprises or discoveries**: Unexpected findings that affect the work
-
-Avoid:
-- Mechanical lists of changes without context
-- Restating what's obvious from code diffs
-- Generic summaries that don't add value
-
-Remember: The goal is to help a future reader (including yourself) quickly understand what matters about this update.

+**Git Commit**: 565782a1c769c90e58e012a80ea1c2d0cfcdb837
+**Branch**: claude-experiments
+**Repository**: zed
+
+## Research Question
+
+We're adding support for custom slash commands to Agent Client Protocol. The client should be able to:
+
+- List available commands
+- Run a command with arguments (check Claude Code behavior)
+
+In the Claude Code ACP adapter, we want implement the _agent_ side of the protocol:
+
+- List commands by reading out of the `.claude/commands` directory
+- Run commands via the SDK
+
+We need to update the protocol to support the new RPCs for listing and running commands.
+We need to understand how to run commands via the SDK.
+
+## Summary
+
+The research reveals a comprehensive architecture for implementing custom slash commands in ACP:
+
+**Claude Code Slash Commands**: Well-established system with 15+ built-in commands, extensible architecture, and consistent execution patterns through the `SlashCommand` trait.
+
+**ACP Protocol**: JSON-RPC based with clear patterns for adding new RPC methods through request/response enums, method dispatch, and capability negotiation.
+
+**Claude Commands Structure**: Markdown-based command definitions in `.claude/commands/` with consistent format, metadata, and programmatic parsing potential.
+
+**SDK Integration**: Claude Code ACP adapter bridges ACP protocol with Claude SDK, providing tool execution and session management through MCP servers.
+
+## Detailed Findings
+
+### Claude Code Slash Command Architecture
+
+**Core Infrastructure** (`crates/assistant_slash_command/`):
+
+- `assistant_slash_command.rs:1-200` - `SlashCommand` trait with `name()`, `description()`, `run()`, `complete_argument()`, `requires_argument()` methods
+- `slash_command_registry.rs:1-150` - Global registry for command registration and lookup
+- `slash_command_working_set.rs:1-100` - Working set management for active commands
+- `extension_slash_command.rs:1-250` - Extension-based command support
+
+**Execution Flow**:
+
+1. Commands registered in `agent_ui.rs:403-448` via `slash_command_registry.register_command()`
+2. User types `/command args` in editor
+3. `SlashCommandCompletionProvider` provides completions
+4. `TextThreadEditor.run_command()` calls `command.run()`
+5. Commands return stream of `SlashCommandEvent`s
+6. Events processed and inserted into context
+
+**Built-in Commands** (`crates/assistant_slash_commands/`):
+
+- File operations: `/file`, `/tab`, `/selection`
+- Development: `/cargo-workspace`, `/diagnostics`, `/symbols`
+- Context: `/context-server`, `/fetch`, `/prompt`
+- Utility: `/now`, `/delta`
+
+### Agent Client Protocol RPC Patterns
+
+**Core Structure** (`agentic-coding-protocol/`):
+
+- JSON-RPC based bidirectional communication
+- Type-safe request/response enums with static dispatch
+- Capability negotiation for feature opt-in
+- Auto-generated JSON Schema from Rust types
+
+**RPC Method Pattern**:
+
+1. Define request/response structs with `#[derive(Serialize, Deserialize, JsonSchema)]`
+2. Add method name constant: `const NEW_METHOD_NAME: &str = "new/method"`
+3. Add variants to `ClientRequest`/`AgentRequest` enums
+4. Update trait definition with async method signature
+5. Add to dispatch logic in `decode_request()` and `handle_request()`
+
+**Existing Methods**:
+
+- `initialize` - Capability negotiation and authentication
+- `session/new`, `session/load` - Session management
+- `session/prompt` - Message processing
+- `fs/read_text_file`, `fs/write_text_file` - File operations
+- `session/request_permission` - Permission requests
+
+### .claude/commands Directory Structure
+
+**Format**: Markdown files with consistent structure:
+
+```markdown
+# Command Name
+
+[Description]
+
+## Initial Response
+
+[Standardized first response]
+
+## Process Steps
+
+### Step 1: [Phase Name]
+
+[Instructions]
+
+## Important Guidelines
+
+[Constraints and behaviors]
+```
+
+**Metadata Extraction Points**:
+
+- H1 title for command name and description
+- "Initial Response" section for invocation behavior
+- Sequential process steps under "Process Steps"
+- Checkbox lists (`- [ ]`, `- [x]`) for progress tracking
+- Code blocks with executable commands
+
+**Command Categories**:
+
+- Development workflow: `create_plan.md`, `implement_plan.md`, `validate_plan.md`, `commit.md`
+- Research: `research_codebase.md`, `debug.md`
+- Project management: `ralph_plan.md`, `founder_mode.md`
+
+### Claude Code ACP Adapter Implementation
+
+**Architecture** (`claude-code-acp/src/`):
+
+- `acp-agent.ts` - Main `ClaudeAcpAgent` implementing ACP Agent interface
+- `mcp-server.ts` - Internal MCP server for file operations and permissions
+- `tools.ts` - Tool conversion between Claude and ACP formats
+- Session management with unique IDs and Claude SDK `Query` objects
+
+**Integration Pattern**:
+
+```typescript
+let q = query({
+  prompt: input,
+  options: {
+    cwd: params.cwd,
+    mcpServers: { acp: mcpServerConfig },
+    allowedTools: ["mcp__acp__read"],
+    disallowedTools: ["Read", "Write", "Edit", "MultiEdit"],
+  },
+});
+```
+
+**Tool Execution Flow**:
+
+1. ACP client makes tool request
+2. Claude ACP agent converts to Claude SDK format
+3. Internal MCP server proxies to ACP client capabilities
+4. Results converted back to ACP format

+## Architecture Insights
+
+**Slash Command System**: Highly modular with clear trait-based abstraction, supports both built-in and extension commands, uses streaming execution model with event-based progress reporting.
+
+**ACP Protocol**: Designed for extensibility with capability negotiation, type safety through Rust enums, symmetric bidirectional design, and JSON-RPC foundation.
+
+**Command Definitions**: Human-readable markdown with programmatically parseable structure, consistent metadata patterns, and workflow automation framework.
+
+**Integration Patterns**: Claude Code ACP adapter provides proven pattern for bridging protocols, MCP servers enable tool execution proxying, session management handles concurrent interactions.
+
+## Implementation Recommendations
+
+### 1. Protocol Extension for Custom Commands
+
+Add new RPC methods to ACP schema:
+
+```rust
+// New request types
+pub struct ListCommandsRequest {
+    pub session_id: SessionId,
+}
+
+pub struct RunCommandRequest {
+    pub session_id: SessionId,
+    pub command: String,
+    pub args: Option<String>,
+}
+
+// Response types
+pub struct ListCommandsResponse {
+    pub commands: Vec<CommandInfo>,
+}
+
+pub struct CommandInfo {
+    pub name: String,
+    pub description: String,
+    pub requires_argument: bool,
+}
+```
+
+### 2. Agent Implementation
+
+In Claude Code ACP adapter:
+
+```typescript
+async listCommands(request: ListCommandsRequest): Promise<ListCommandsResponse> {
+  // Read .claude/commands directory
+  // Parse markdown files for metadata
+  // Return CommandInfo array
+}
+
+async runCommand(request: RunCommandRequest): Promise<RunCommandResponse> {
+  // Find command definition in .claude/commands/
+  // Execute via Claude SDK query with command content
+  // Stream results back via session notifications
+}
+```
+
+### 3. Command Parsing
+
+Implement markdown parser for `.claude/commands/*.md`:
+
+```typescript
+function parseCommandFile(content: string): CommandInfo {
+  // Extract H1 title for name/description
+  // Find "Initial Response" section
+  // Parse metadata and requirements
+  // Return structured command info
+}
+```
+
+## Open Questions
+
+1. **Command Arguments**: How should complex command arguments be structured and validated?
+
+2. **Command Context**: Should commands have access to current session state, file context, or conversation history?
+
+3. **Command Discovery**: Should commands be cached or re-read on each listing request?
+
+4. **Extension Commands**: How should extension-provided commands integrate with `.claude/commands/` file-based commands?
+
+5. **Command Execution**: Should commands run in isolated contexts or share session state?
+
+6. **Error Handling**: What's the appropriate error handling strategy for command parsing and execution failures?
+
+###### FINAL CLAUDE PROMPT:
+
+⏺ I've completed comprehensive research on adding custom
+slash commands to the Agent Client Protocol. Here's what
+I found:
+
+Key Findings
+
+Slash Command Architecture: Claude Code has a
+well-established slash command system with 15+ built-in
+commands using a SlashCommand trait. Commands are
+registered globally and execute through streaming events.
+
+ACP Protocol Patterns: The protocol uses JSON-RPC with
+type-safe request/response enums. Adding new RPC methods
+follows a clear pattern: define structs, add to enums,
+update dispatch logic.
+
+.claude/commands Structure: Commands are defined as
+structured Markdown files with consistent format -
+perfect for programmatic parsing. Each contains metadata,
+process steps, and execution guidelines.
+
+SDK Integration: The Claude Code ACP adapter already
+bridges ACP with the Claude SDK through MCP servers,
+providing a proven pattern for command execution.
+
+Implementation Approach
+
+You'll need to:
+
+1. Extend ACP Protocol: Add ListCommandsRequest/Response
+   and RunCommandRequest/Response to the schema
+2. Parse Command Definitions: Read .claude/commands/\*.md
+   files and extract metadata (name, description,
+   requirements)
+3. Execute Commands: Run commands via Claude SDK queries,
+   similar to how the current ACP adapter works
+4. Handle Streaming: Use ACP's session notification
+   system to stream command progress
+
+The research document is saved at thoughts/shared/researc
+h/2025-08-28_15-34-28_custom-slash-commands-acp.md with
+detailed implementation recommendations, code references,
+and open questions for your consideration.
