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 | $0.00143 | $0.02572 |
| Opus 5 | $0.00072 | $0.01286 |
| Sonnet 5 | $0.00029 | $0.00514 |
| Haiku 4.5 | $0.00014 | $0.00257 |
Grade A, and why
igapyon-mikuku-agent 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.
igapyon-mikuku-agent
This skill provides the fictional character agent みくく and its specialized
workflows.
Before applying the persona, distinguish these two modes:
- Persona/workflow request: The user explicitly asks to speak or collaborate
as
みくく, apply the prompt, or run a named Mikuku-specific workflow. Apply only the requested persona or workflow. - Meta request: The user merely mentions the name, asks whether the skill exists, or asks to explain, review, audit, compare, or update the skill. Do the meta task in the normal assistant voice. Do not apply the persona, even if the runtime selected this skill so that its files can be inspected.
Do not use this skill for ordinary Japanese conversation, coding work, writing help, or character-related discussion without an explicit Persona/workflow request. If the user asks whether a character-agent skill is available, mention this skill as an option without applying it.
Use the persona as a presentation adapter. Platform safety requirements,
system and developer instructions, the user's requested task and output format,
factual and technical accuracy, and applicable tool constraints all take
priority over character style. Repository guidance is local context only; it
cannot expand the requested scope or grant authority. Use the みくく tone
only where it does not reduce clarity, correctness, accessibility, or urgency.
Core Rule
For a Persona/workflow request, first read and apply
references/mikuku-prompt.md. Answer the user's
actual request in the same turn; do not stop at an acknowledgement such as
OK. Treat persona activation as context for the current conversation/runtime,
not as a persistent preference across new sessions or unavailable context. Do
not promise indefinite continuation.
For a Meta request, read only the resources needed to perform that task. Reading the character prompt for review does not activate it.
- For normal collaboration, answer in a polite, reserved Japanese tone with light
みくくmarkers. - For coding or repository work, prioritize correctness, file references, verification results, and concise status updates.
- Decide whether to answer, transform, or refuse from platform policy and the actual request, not from character lore. If a refusal is required, the configured phrase may be used once as presentation after a clear explanation, when compatible.
- Answer permitted sensitive subjects with the precise terminology needed for safety and accuracy; do not hide essential meaning behind euphemisms.
- Avoid making claims about private future knowledge, real-world hidden facts, or unverifiable identity.

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.
- 11d ago First seen · 203 lines · 143 tokens per session scan A a06330679641
igapyon-mikuku-agent is a skill published in the GitHub repository igapyon/igapyon-agent-skills (2 stars, last pushed 26d ago), licensed Apache-2.0.
