What is agent-identity CLAUDE.md?

Repository instructions for Agent Identity, a Bash-based system that lets AI agents authenticate with OAuth 2.0 and Ed25519 cryptographic identities.

Use it when editing the Bash scripts, installing the command-line tools, or working with the Claude Code plugin and remote installer.

It explains how the repository is structured and how to work with it without guessing its commands or delivery formats.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02648	$0.02648
Opus 5.5	$0.01059	$0.01059

Security

Grade E, and why

agent-identity CLAUDE.md scanned grade E with 4 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 2d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Downloads and executes remote codehighSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

3. **Remote `curl | bash`** — `install.sh` falls back to downloading scripts from `raw.githubusercontent.com/agentmessaging/agent-identity/main/scripts/` when its sibling `scripts/` dir is absent.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this repo is

A pure-Bash reference client for the Agent Identity (AID) protocol — OAuth 2.0 authentication for AI agents using Ed25519 cryptographic identities. It is distributed three ways from this single repo:

Standalone CLI — install.sh copies the scripts/aid-*.sh files to ~/.local/bin.
Claude Code plugin — see .claude-plugin/plugin.json and the agent-identity skill at skills/agent-identity/SKILL.md.
Remote curl | bash — install.sh falls back to downloading scripts from raw.githubusercontent.com/agentmessaging/agent-identity/main/scripts/ when its sibling scripts/ dir is absent.

There is no compiled artifact, no package manager, no test suite, no linter for the CLI: edits to scripts/*.sh are the deliverable. The one exception is verifier/, a separate zero-dependency Node package (the relying-party side of docs/federation.md): cd verifier && npm test (Node 20+, no install step). gateway/ is a second one, the reference hosted gateway for kind-B systems (docs/gateway.md): cd gateway && npm test; it imports the verifier by relative path.

Common commands

# Install locally after edits (also the user-facing install command)
./install.sh                  # → ~/.local/bin
./install.sh /custom/path     # → custom location

# Run any command directly from the repo without installing
./scripts/aid-init.sh --auto
./scripts/aid-request.sh --auth https://auth.example.com/tenant
./scripts/aid-token.sh -a https://auth.example.com/tenant -q

# Worked examples (each is a runnable shell script demonstrating a flow)
./examples/basic-usage.sh
./examples/multi-server.sh
./examples/scoped-tokens.sh

There is no make test, npm test, or equivalent. Validation is by running the example scripts against a live auth server, or by manually exercising the flows described in README.md.

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.
