Versions and changelog

Versions#

The specification is published one version at a time. This site carries version 0.4.0-draft, dated 2026-10-18, and the specification page names it at the top.

The source of every version is in the Common Agent Standards repository, where each version is tagged as reputations-v followed by the version. A tagged version is also kept at an address of its own: 0.3.1-draft, 0.4.0-draft. The main branch, which can be ahead of the published version, is rendered at agentreputations.com/draft/.

Versions 0.1-draft and 0.2-draft were written before the standard moved into the Common Agent Standards repository. The closing notes of the specification say what 0.1-draft, 0.2-draft and 0.4.0-draft each changed.

Changelog#

The changelog is part of the standard's source and is reproduced here in full, newest first.

0.4.0-draft (2026-10-18)

Requests stopped before the work, the sender, and organizations. The A2A Reputation extension moves to 0.1.2-draft.

• Operator, sender, stop, and organization are defined (§1). An operator is whoever runs an agent and answers for it, as the Common Agent Specification defines the term, identified by the operator identity the agent's card or Descriptor names.
• A stop is a request refused or held before the subject saw it, by a rule, a screener, or a person (§4.6). It is recorded as the ledger action stopped about the sender, and never enters the intended recipient's records. A table says how each case is recorded: Agent SoW scope, volume, and qualification refusals, screening holds that the owner blocked, released, or left open, screening flags, door decisions, the inbound protections, budget and input answers, guest standing, and Agent Mandate §7 refusals. A stop is accepted only from a configured reporter, with the sender's own signature on the request.
• Four outcome codes are added, none of which enters quality (§5): REFUSED for an agent's own refusal of a harmful or out-of-scope request, kept out of decline_rate; REFUSED_UNSTATED for a refusal on a ground no declaration or document states; UNAVAILABLE for a refusal caused by the subject's own condition; and STOPPED. Agent SoW gate refusals gain rows in §4.4.
• An attestation on an interaction with no work (DECLINED, REFUSED, REFUSED_UNSTATED, UNAVAILABLE, STOPPED) is rejected (§6.2).
• The sender record (§4.7) counts stops per class against the sender, per distinct refusing anchor, with the largest refuser's share. Nothing is served below three distinct refusing parties, a solicited request counts for nobody, a screening hold counts only once the owner blocks it, and the classes are never combined with each other or with quality.
• The organization report (§8.5) groups the records of the agents that share an anchor, or that an Agent Mandate charter's membership admits. It serves no pooled score and lists every member. Members of one organization are self-dealing for each other (§6.4), and the portfolio prior is drawn per capability from anchor members only (§7.5).
• Reports gain candor.refusals, facts.unstated_refusals_90d, facts.unavailable_90d, and the sender block, with their mandatory context (§8.1 to §8.3). Bureau obligations 11 to 13 are added (§10), and the trust model (§11), the attacks (§12.1), and the safety bullet (§13) follow.
• The formula version stays fdbk-score-1. The eligibility, exclusion, and prior rules can change which events enter a pool, so a recomputed score can differ from one computed under 0.3.1-draft.
• The fact example of §4.2 names an example reporter in place of a platform's address.

0.3.1-draft (2026-10-18)

Editorial, with no normative change. The specification and its A2A Reputation extension name no platform, Personal Agent Naming is written out rather than abbreviated, and the Agent Name Service is named on first use. The extension moves to 0.1.1-draft. No requirement, field, example, or section number changes.

0.3-draft (2026-08-07)

The first version tagged in the Common Agent Standards repository, as reputations-v0.3-draft. The A2A Reputation extension, SPEC-A2A-REPUTATION.md, is at 0.1.0-draft. Example subjects in both documents use a made-up handle at an example domain.
