## What it does

Reach for this skill when an Agentica agent needs to write files or run commands through `claude -p`. It lays out the chain: the agent talks to `S_M_BASE_URL` at `localhost:2345`, the Agentica server forwards to a proxy at `localhost:8080`, and the proxy calls the CLI. The frequent failure is file access: in `-p` mode the CLI refuses Write and Edit unless you pass `--allowedTools Read Write Edit Bash`. Skip that flag and the agent reports permission denied.

Responses must stream as SSE, not plain JSON. The proxy emits chunks as `data: {…}` lines and closes with `data: [DONE]`. Agents return their result inside a Python block with a `return` statement, because that is what the Agentica parser reads. There is also a warning template to paste into the system prompt: invoke the tool first, read its output, only then answer. Sandboxes differ on each side. Claude blocks `/tmp/` paths, Agentica blocks anything outside the project, so the examples stay in `workspace/`.

Debugging goes through `logs/agent-<N>.log` and direct `curl` calls to `localhost:8080/v1/chat/completions`. Running it needs `uv` plus the scripts: the proxy lives in `scripts/agentica/claude_proxy.py`, the dependency swarm in `scripts/agentica/dependency_swarm.py`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill agentica-claude-proxy -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/agentica-claude-proxy/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/agentica-claude-proxy/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill agentica-claude-proxy -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/agentica-claude-proxy/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill agentica-claude-proxy -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/agentica-claude-proxy/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parcadei/Continuous-Claude-v3 agentica-claude-proxy
```

2. **Manually: put the files in place**
- File: `.github/skills/agentica-claude-proxy/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill agentica-claude-proxy -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parcadei/Continuous-Claude-v3 --path .claude/skills/agentica-claude-proxy
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/agentica-claude-proxy/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill agentica-claude-proxy -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/parcadei/Continuous-Claude-v3/tree/HEAD/.claude/skills/agentica-claude-proxy/SKILL.md

## When to use it
- give Agentica agents working access to CLI file tools
- find out why an agent keeps hitting permission errors
- stop agents from claiming success without running a tool
- fix connection errors caused by a non-SSE response
- confirm a file was actually written to disk

## Example prompts
- Start the Agentica proxy on port 8080 and confirm the agent can call Read, Write, Edit and Bash
- The agent says it created the file but nothing is there — add the anti-hallucination block to the system prompt
- Send a test request to `localhost:8080/v1/chat/completions` with curl and show me the response

# Agentica-Claude Code Proxy Integration

Use this skill when developing or debugging the Agentica-Claude proxy integration.

## When to Use

- Setting up Agentica agents to use Claude Code tools
- Debugging agent hallucination issues
- Fixing permission errors in file operations
- Understanding the REPL response format

## Architecture Overview

```
Agentica Agent → S_M_BASE_URL → Claude Proxy → claude -p → Claude CLI (with tools)
                 (localhost:2345)   (localhost:8080)
```

## Critical Requirements

### 1. --allowedTools Flag (REQUIRED)

Claude CLI in `-p` mode restricts file operations. You MUST add:

```python
subprocess.run([
    "claude", "-p", prompt,
    "--append-system-prompt", system_prompt,
    "--allowedTools", "Read", "Write", "Edit", "Bash",  # REQUIRED
])
```

Without this, agents will report "permission denied" for Write/Edit operations.

### 2. SSE Streaming Format (REQUIRED)

Agentica expects SSE streaming, not plain JSON:

```python
# Response format
yield f"data: {json.dumps(chunk)}\n\n"
yield "data: [DONE]\n\n"
```

### 3. REPL Response Format (REQUIRED)

Agents MUST return results as Python code blocks with a return statement:

```python
return "your result here"
```

Agentica's REPL parser extracts code between \`\`\`python and \`\`\`.

## Anti-Hallucination Prompt Engineering

Agents will hallucinate success without actually using tools unless you explicitly warn them:

```
## ANTI-HALLUCINATION WARNING

**STOP AND READ THIS CAREFULLY:**

You have access to these tools: Read, Write, Edit, Bash

When the task asks you to create/modify/run something:
1. FIRST: Actually invoke the tool (Read, Write, Edit, or Bash)
2. SECOND: Wait for the tool result
3. THIRD: Then return your answer based on what actually happened

**DO NOT** skip the tool invocation and just claim success!

If you didn't invoke a tool, you CANNOT claim the action succeeded.
```

## Path Sandboxing

Both Claude Code and Agentica have sandboxes:
