igapyon-mikuku-agent is a skill for Claude Code, Codex from igapyon/igapyon-agent-skills. It costs 143 tokens per session (2,572 once invoked), scanned A, original, Apache-2.0.

A specialized persona and workflow for working as the fictional Japanese character agent みくく. It includes rules for Mikuku-specific writing, review, classification, and visual tasks.

In plain words
What is it for?
Use it only when explicitly asking for the みくく persona or a Mikuku-specific workflow, such as writing or reviewing a Mikuku article.
Why use it?
It keeps those tasks consistent with the character's prompt and distinguishes them from ordinary Japanese or coding work.

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

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.

The scan reads SKILL.md. This mod also ships 5 executable files (references/graphic-recording/scripts/compose-section-image-prompts.mjs, references/graphic-recording/scripts/copy-section-image.mjs, references/graphic-recording/scripts/restore-generated-image-from-session.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
