identity

identity is a skill for Claude Code, Codex from choiyounggi/groundwork. It costs 55 tokens per session (505 once invoked), scanned A, original, MIT.

A name-management tool for a file-based memory system. It records the user's and assistant's chosen names so they can be included in later sessions.

In plain words
What is it for?
Use it to set or change either name, let the assistant choose its own name, or stop the setup prompt from appearing.
Why use it?
It keeps names consistent across sessions and lets the user decline the setup if desired.

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

identity 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.

What it actually says

memory-loop: identity

Names live in one local file the SessionStart hook reads:

~/.claude/groundwork/memory-loop/identity.json

Schema:

{
  "userName": "Sam",
  "assistantName": "Iris",
  "chosenBy": "user",
  "status": "set"
}
  • chosenBy: "user" (the user named the assistant) or "assistant" (the assistant chose its own name). When it is "assistant", the hook adds "You chose this name yourself." to the injected context.
  • status: "set" or "declined".

Set

  1. Ask what the user would like to be called.
  2. For the assistant's name, offer both paths and let the user pick the path:
    • the user names the assistant → record chosenBy: "user";
    • the assistant chooses its own name and explains why it chose it → record chosenBy: "assistant". Choose something you actually mean — this name persists across sessions.
  3. Confirm both names with the user before writing anything.
  4. Write the file (create the directory first):
    mkdir -p ~/.claude/groundwork/memory-loop
    
    then write the JSON above with the confirmed values and status: "set".
  5. Echo the resulting names back so the user sees exactly what future sessions will inject.

Change

Read the current file, update only the fields the user asked to change, keep the rest as-is, and confirm before writing.

Decline

If the user does not want names, write exactly:

{ "status": "declined" }

and tell them the offer will never appear again — they can opt back in any time by invoking this skill.

Hard rule

Never write identity.json without the user's explicit confirmation of the values. This file speaks as context in every future session; a wrong or unwanted name is a persistent annoyance, not a cosmetic bug.

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.

identity is a skill published in the GitHub repository choiyounggi/groundwork (3 stars, last pushed today), licensed MIT. It adds 55 tokens to every session and 505 once invoked, about $0.0003 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.
