atrib CLAUDE.md

atrib CLAUDE.md is an instructions file for coding agents from creatornader/atrib. It costs 20,198 tokens per session, scanned A, original, Apache-2.0.

Instructions for atrib, a protocol that creates signed, linked records of actions taken by AI agents. These records can be checked independently through a public Merkle log, a tamper-evident record structure.

In plain words
What is it for?
Use it when recording tool calls, payments, observations, revisions, or lookups that need an independently verifiable history.
Why use it?
It helps make agent actions auditable and verifiable instead of relying only on the operator’s claims. It also explains how hosts and later workflows can check and carry forward signed context.

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

atrib CLAUDE.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 3d 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.

atrib: the protocol for verifiable agent actions

What this is

atrib makes the actions an AI agent takes provable. Every agent action becomes a signed, chain-linked record committed to a public Merkle log. Downstream consumers (the agent itself, merchants, auditors, other agents) can independently verify what happened without trusting any operator.

Product teams can put that record in the action path. A host can check an action before it runs, and later work can carry the signed context forward. atrib records tool calls (MCP via @atrib/mcp-wrap, framework-native via @atrib/agent or @atrib/openinference), transactions (six payment protocols detected per the payments profile: ACP, UCP, x402, MPP, AP2, a2a-x402), and the agent's own intentional records and reads through the two cognitive verbs: attest (write: observation by default, annotation via ref.kind: "annotates", revision via ref.kind: "revises") and recall (read: shape-dispatched lookups, lineage walks, and handoff verification). The seven legacy primitive names (emit, atrib-annotate, atrib-revise, the recall_* family, trace, summarize, atrib-verify) stay mounted as permanent aliases over the same handlers per D164; records are byte-identical either way.

The same substrate supports agent recall, third-party audit, commerce settlement, handoffs, and controlled high-impact actions when a harness or runtime puts atrib records in the action path. atrib sits between identity (DIF/W3C) and payment rails (ACP/UCP/x402/MPP/AP2). It also makes post-hoc claims about agent activity provable.

When explaining the graph, keep the D118 framing stable: atrib has one graph with two reading planes. The chronology plane records event history and continuity. The declared-relationship plane records signed claims about which records informed, anchored, annotated, or revised other records. /v1/chain and /v1/trace are projections over that graph, and the explorer primary trace path is a product presentation rule over both projections.

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.

atrib CLAUDE.md is an instructions file published in the GitHub repository creatornader/atrib (9 stars, last pushed 3d ago), licensed Apache-2.0. It adds 20,198 tokens to every session, about $0.1010 per session on Opus 5. 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 2026-08-31.
