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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00340 | $0.00340 |
| Opus 5 | $0.00170 | $0.00170 |
| Sonnet 5 | $0.00068 | $0.00068 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
amp-acp AGENTS.md 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 10d ago.
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.

Architecture
This is an ACP (Agent Client Protocol) adapter that bridges Amp Code to ACP-compatible clients like Zed.
src/index.ts— Entry point, redirects console to stderr (stdout reserved for ACP stream)src/run-acp.ts— Sets up ACP connection using stdin/stdout JSON streamssrc/server.ts—AmpAcpAgentclass: handles sessions, prompts, MCP config, and calls@ampcode/sdk(formerly@sourcegraph/amp-sdk)src/to-acp.ts— Converts Amp stream events to ACPsessionUpdatenotificationssrc/mcp-config.ts— Converts ACP MCP server configs to Amp SDK formatsrc/utils.ts— Node-to-Web stream converters
Code Style
- TypeScript with ES modules (
"type": "module"in package.json), use.jsextension in imports - Strict mode enabled; avoid
anyand type assertions unless necessary - Use
console.errorfor logging (stdout is for ACP protocol only) - Error handling: throw
RequestErrorfrom@agentclientprotocol/sdkfor protocol errors - Naming: camelCase for variables/functions, PascalCase for classes/interfaces
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.
