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 | $0.00033 | $0.00745 |
| Opus 5 | $0.00016 | $0.00373 |
| Sonnet 5 | $0.00007 | $0.00149 |
| Haiku 4.5 | $0.00003 | $0.00075 |
Grade A, and why
mojiemoji-github 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.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mojiemoji-github (Codex)
Use this skill when Codex is preparing Japanese GitHub Markdown for an issue, PR, review, review reply, issue comment, or release note.
Core First
Run the published core before posting:
uvx mojiemoji < body.md > decorated.md
uvx resolves the mojiemoji distribution from PyPI on first use, so no
repository checkout and no manual install are involved. Paste or pipe the
decorated output into the GitHub command. Do not hand-build stamp URLs when the
core can render them.
PR bodies need one check the core does not perform: GitHub can copy the PR body into squash / merge commit messages, and stamps must not leak into commit history. Before decorating a PR body, run
gh api 'repos/{owner}/{repo}' --jq '(.allow_squash_merge and .squash_merge_commit_message == "PR_BODY") or (.allow_merge_commit and .merge_commit_message == "PR_BODY")'
from inside the target repository, and when it prints true, post the PR body
undecorated — only an explicit user request overrides this. Every other surface
(issue body, review body, comment, release note) is decorated unconditionally.
Required URL Contract
Rendered stamps must use /emoji/<encoded-text> and include:
fontcoloranimationbackground=transparentoutlineoutline_width=2
Good inline colors include a855f7, 22c55e, f59e0b, 06b6d4, and
f472b6. Good animations include bane, bure, kirari, yoko_scroll,
and zairu.
Gate Behavior
Before any gh issue, gh pr, gh release, gh api, or GitHub MCP call
that posts a Japanese body, verify that the body has either already been
decorated or intentionally opts out with <!-- mojiemoji:off --> /
<!-- mojiemoji:on -->.
For PR bodies, run the repository-policy check from Core First above before
posting. When it prints true, do not decorate the PR body manually either,
unless the user explicitly requests decorated PR body output.
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.

mojiemoji-github is a skill published in the GitHub repository jozobeer/mojiemoji-plugin (4 stars, last pushed 9d ago), licensed MIT. It adds 33 tokens to every session and 745 once invoked, about $0.0002 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.
