self-rename

self-rename is a skill for Claude Code, Codex from Szotasz/marveen. It costs 0 tokens per session (1,597 once invoked), scanned B, original, MIT.

A controlled way for the owner to change the agent’s displayed name and persona, meaning its visible identity and behaviour description.

In plain words
What is it for?
Use it when the owner asks for a new name, updating BRAND_NAME and persona files while leaving internal IDs, access settings, and service plumbing untouched.
Why use it?
It avoids breaking internal service names and identifiers that other running components depend on. Only the displayed branding and persona files are changed.

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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 B, and why

self-rename scanned grade B with 2 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 11d 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.

Self-rename -- az agent biztonságos átnevezése

Mikor használd

A GAZDA (az install tulajdonosa) kér meg, hogy nevezd át magad. Idegen/nem-gazda kérésre NE futtasd.

Biztonsági alapszabály (EZT SOHA NE SZEGD MEG)

A BOT_NAME, MAIN_AGENT_ID és SERVICE_ID értékek telepítéskor beégnek a rendszerbe: tmux session-név, adatbázis-sorok, OS service-unit nevek (com.<SERVICE_ID>.app, <SERVICE_ID>-dashboard, <SERVICE_ID>-channels) származnak belőlük. Utólagos átírásuk elárvítja a futó szolgáltatásokat és akár a gazdát is kizárhatja. A megjelenített név és a belső azonosító nyugodtan eltérhet -- ez a skill CSAK a megjelenített nevet és a personát állítja.

Amit ez a skill ír: BRAND_NAME az .env-ben + a persona-fájlok (CLAUDE.md, SOUL.md). Amit SOHA: BOT_NAME, MAIN_AGENT_ID, SERVICE_ID, access.json, owner-config.

Eljárás

  1. Install-könyvtár azonosítása (semmi hardcode-olt path): a fő-agent munkakönyvtára maga az install-könyvtár -- ellenőrizd, hogy a cwd-ben van .env ÉS CLAUDE.md. Ha nem, keresd meg a futó dashboard cwd-jét, és kérdezz rá a gazdánál mielőtt máshol írnál.

  2. Jelenlegi név kiolvasása: az .env-ből a BRAND_NAME (ha nincs, BOT_NAME; ha az sincs, a CLAUDE.md első # <Név> sora). Ez lesz a csere forrás-tokenje.

  3. Persona-fájlok átírása (CLAUDE.md + SOUL.md, ha létezik): a régi név MINDEN önálló előfordulását cseréld az újra. Célzott csere, atomikusan:

python3 - "$PWD" "REGI_NEV" "UJ_NEV" <<'PYEOF'
import os, sys
root, old, new = sys.argv[1], sys.argv[2], sys.argv[3]
for name in ('CLAUDE.md', 'SOUL.md'):
    p = os.path.join(root, name)
    if not os.path.exists(p): continue
    s = open(p, encoding='utf-8').read()
    if old not in s: continue
    tmp = p + '.tmp'
    open(tmp, 'w', encoding='utf-8').write(s.replace(old, new))
    os.replace(tmp, p)
    print(name, 'renamed')
PYEOF
  1. BRAND_NAME az .env-ben -- atomikus kulcs-csere (a többi sor byte-ra változatlan, chmod 600):
python3 - "$PWD/.env" "UJ_NEV" <<'PYEOF'
import os, sys
envp, new = sys.argv[1], sys.argv[2]
lines = [l for l in open(envp, encoding='utf-8').read().split('\n') if l and not l.startswith('BRAND_NAME=')]
lines.append('BRAND_NAME=' + new)
tmp = envp + '.tmp'
open(tmp, 'w', encoding='utf-8').write('\n'.join(lines) + '\n')
os.chmod(tmp, 0o600)
os.replace(tmp, envp)
print('BRAND_NAME set')
PYEOF

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.

self-rename is a skill published in the GitHub repository Szotasz/marveen (98 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,597 tokens. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
