Claude

A built-in way to start Claude coding-agent sessions through ACPX, a tool that connects software agents to compatible clients.

In plain words
What is it for?
Use it to start or reconnect Claude sessions, restore selected model and effort settings, and control whether global Claude settings are loaded.
Why use it?
It keeps project and local settings available while avoiding conflicts from globally enabled Claude extensions. User-wide settings can be included only when needed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Claude scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Claude

  • Built-in name: claude
  • Default command: npx -y @agentclientprotocol/claude-agent-acp
  • Upstream: https://github.com/agentclientprotocol/claude-agent-acp
  • ACPX pins the built-in package range so fresh installs pick up Claude model and ACP adapter fixes without depending on a global adapter binary.
  • Model switches can change the available effort controls. ACPX updates existing saved effort selections from the accepted response and removes selections whose controls disappear.
  • Saved model and config selections are restored after reconnect, without replacing the conversation.

Settings isolation

Built-in acpx claude sessions load Claude project and local settings, but not user settings. This prevents globally enabled channel and daemon plugins from claiming singleton external resources in an ACP-spawned session.

Set ACPX_CLAUDE_INCLUDE_USER_SETTINGS=1 only when the spawned session needs the user's global Claude settings and no such plugin conflict exists. Ambient credentials and other environment variables are still inherited normally.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Claude is an agent published in the GitHub repository openclaw/acpx (3,194 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 217 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
