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 | $0.00095 | $0.01654 |
| Opus 5 | $0.00048 | $0.00827 |
| Sonnet 5 | $0.00019 | $0.00331 |
| Haiku 4.5 | $0.00010 | $0.00165 |
Grade A, and why
igapyon-github-writer 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 5d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
igapyon-github-writer
This skill drafts Markdown text for GitHub surfaces from local repository evidence. It can also save drafted GitHub text to a local Markdown file, rebuild local commits with soft reset and a drafted PR text as the commit message, create a local backup branch at the current HEAD, and report the current branch status as preparation for GitHub writing work.
Use it only for GitHub writing text, local draft-file saving for that text, explicit PR soft-reset recommit work, explicit local backup-branch creation, and the local branch-status checks that prepare that writing. Do not create PRs, tags, releases, issues, non-backup branches, or remote changes. Local commits are allowed only inside the explicit PR Soft Reset Recommit workflow.
GitHub CLI And Network Boundary
Never invoke gh, either directly or through a bundled helper. This skill has
no network workflow and no remote-mutation workflow. A user request for remote
GitHub inspection or mutation does not relax this boundary; stop this skill's
workflow and report that the operation is unsupported here. Read and apply
references/github-cli-prohibition.md.
Do not use this skill for generic commit summaries, changelogs, branch inspection, backup operations, or repository cleanup unless the user explicitly asks for GitHub PR, GitHub Release, GitHub About text, PR soft-reset recommit from drafted PR text, local backup-branch creation through this skill, branch status through this skill, or names this skill.
If the user asks whether there is a skill for GitHub PR, Release, or About text, mention this skill as an available option, but do not apply it until the user asks to use it.
Mode Phrases
After this skill is active, choose the workflow mode from the user's wording. The wording does not need to exactly say pr text or release text; similar phrases are enough.
Examples:
- PR mode:
pr textつくりたい,PR文面を作りたい,pull request本文,プルリク説明,PRタイトルと本文 - Release mode:
release textつくりたい,リリース文を作りたい,release notes,リリースノート,GitHub Release本文 - About mode:
GitHub Aboutを書きたい,About文,リポジトリ説明,GitHub説明文 - PR Soft Reset Recommit mode:
PR文面でsoft resetしてcommitし直す,PR文面をcommit messageに反映して再コミット,作文したPR文面でgit commitし直す - Backup Branch mode:
github-writerでバックアップブランチ,backup/2026-06-27-2230 みたいなブランチを作る,現在HEADをバックアップ,soft reset前のバックアップだけ作る - Branch Status mode:
github-writerでブランチ状況,今のブランチの状況,PR前にブランチ状態を見たい,現在ブランチの確認

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.

igapyon-github-writer is a skill published in the GitHub repository igapyon/igapyon-agent-skills (2 stars, last pushed 21d ago), licensed Apache-2.0. It adds 95 tokens to every session and 1,654 once invoked, about $0.0005 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.
