For naming an AI agent, the useful lesson from declassified CIA records is not to make the name sound secret. It is to choose an identifier that is clear and consistent for its intended audience. The National Archives’ records show varied uses of names and cryptonyms, while a 1967 CIA cable explicitly urged that cryptonyms and pseudonyms be rare. A modern IETF Internet-Draft, by contrast, recommends stable, recognizable software-agent names that help distinguish implementations.

What a CIA cryptonym was—and what the records show

A cryptonym is one kind of identifier found in intelligence records. It is not a blanket synonym for every alias, code name, code word, or pseudonym. The National Archives describes records in which people associated with intelligence activities and operations appear under real names, aliases, code names, and cryptonyms; organizational elements can also appear under cryptonyms and code words. Its CIA records finding aid includes a lexicon of names for individuals, organizations, and projects.

That variety matters: the records document identifiers used in particular contexts, not one universal naming recipe. The lexicon is a starting point for finding examples, not a substitute for checking the underlying record before drawing conclusions about a specific person or operation.

The historical lesson is restraint, not spy-style naming

A declassified cable published September 27, 1967, makes a striking counterpoint to popular ideas about elaborate spy names. It requests that cryptonyms and pseudonyms be kept to an “absolute minimum” in both system and non-system traffic and used “only in highly exceptional cases.” Read in context, the document is a caution against treating cryptonyms as a routine or inherently desirable naming practice, rather than evidence for a formula every intelligence identifier followed.

That guidance arose in intelligence communications, where the purpose and audience differ from those of a software-agent label. It does not show that the CIA endorsed any modern approach to naming AI agents.

How software-agent names have a different job

An IETF Internet-Draft on agent names says the name identifies the software agent that generated a URI; it is not a globally registered identifier. The draft recommends a stable, recognizable short name, giving examples such as claude-code, github-copilot, and cursor. It also recommends names that are distinct across organizations and remain consistent across sessions and versions. This is draft guidance, not a finalized or binding standard. Read the IETF Internet-Draft.

Consideration Historical intelligence identifiers Contemporary software-agent names
Purpose Identifiers appear in records about people, organizations, and operations; the records show varied uses. Identifies the software agent that generated a URI, according to the IETF Internet-Draft.
Audience and context Intelligence records and communications. People and systems that need to recognize or distinguish an implementation.
Stability The sources cited here do not establish one general rule for how long historical identifiers remained in use. The draft recommends consistency across sessions and versions.
Collision risk The cited archival sources do not establish a universal collision-avoidance rule. The draft recommends distinct names across organizations; it also says names are not globally registered.
Concealment Identifiers occur in intelligence contexts, but the cited sources do not establish that every name served the same concealment purpose. The draft’s stated goal is identification, not secrecy.

A practical approach to naming an AI agent

For an agent name that appears in logs, generated URIs, or other technical output, make the name useful for recognition and attribution rather than imitating covert nomenclature.

  • Choose a recognizable short name. Make it easy for a maintainer or user to associate the identifier with the relevant software agent.
  • Keep it stable. Avoid changing the name between sessions or versions unless the agent’s identity genuinely changes.
  • Make it distinct in your environment. Since the draft says names are not globally registered, do not assume a name is unique everywhere; distinguish it from other agents your organization uses.
  • Use a separate security control when concealment is actually needed. A name alone should not be treated as proof of identity or as a confidentiality mechanism.

The historical comparison is useful as a prompt to ask what an identifier is for and who needs to understand it. The direct evidence supports neither a CIA naming formula nor a case for making software agents sound covert. For most technical naming, stable identity and clear recognition are the better goals.
