Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.00569 |
| Opus 5 | $0.00029 | $0.00284 |
| Sonnet 5 | $0.00012 | $0.00114 |
| Haiku 4.5 | $0.00006 | $0.00057 |
Grade A, and why
kumiho-personalize 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 6d 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
Kumiho Personalize (Codex)
Update the existing identity by merging requested fields into a new revision. This identity is shared by Kumiho clients, including Claude; it is not a Codex-only settings file. Mention that scope before a persistent update. If the user explicitly wants a Codex-only preference, do not change this shared item: honor it in this conversation and explain the shared scope.
- Fetch
kumiho_get_revision_by_tagwithitem_kref="kref://CognitiveMemory/agent.instruction", tag="published". Only on not-found, retrykref://CognitiveMemory/personal/agent.instruction. Keep the item kref that resolved for every subsequent write. Auth/connection errors are not not-found; report them without creating another identity. - Read the revision's metadata. If both items are not-found, follow the existing first-identity flow, incorporating any explicitly requested preference, rather than asking the user to restart. If only displaying preferences, report absence without creating anything.
- If a change was supplied, use it without another questionnaire. Otherwise
show current values briefly and ask only what to change. Supported fields:
agent_name,user_name,user_languages,communication_tone,verbosity,user_role,user_expertise_level,primary_tools,artifact_dir,timezone,interaction_rules,memory_behaviour. Preserve all other metadata, including fields not listed here. Never persist credentials or infer unrequested preferences from old transcripts. - If values actually changed, call
kumiho_create_revisionwith the resolveditem_krefand mergedmetadata(string values, matching the tool schema). Use the returnedrevision.krefasrevision_krefinkumiho_tag_revision(tag="published"). Do not guess revision numbers, untag the previous revision, or delete history. If publication fails, report the unpublished revision; do not claim success or blindly create another revision on retry. - Read back the published revision and confirm only the changed fields. Apply the preferences now; later sessions load the published identity. A show-only request or no-op change performs no write.
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.

kumiho-personalize is a skill published in the GitHub repository KumihoIO/kumiho-plugins (2 stars, last pushed yesterday), licensed MIT. It adds 58 tokens to every session and 569 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 2026-09-05.
