prepare-release

prepare-release is a skill for Claude Code, Codex from ayutaz/piper-plus. It costs 95 tokens per session (2,969 once invoked), scanned A, original, MIT.

A release-preparation checker for nine packages and five package registries, which are services that distribute software packages. It prepares version changes, lockfile updates, Swift checksums, change-log edits, publishing order, and post-release checks.

In plain words
What is it for?
Use it to prepare a Python, Rust, C#, npm, Swift, or Kotlin release at a chosen version. It can produce a dry-run plan or, with the apply option, make the version updates after confirmation.
Why use it?
It reduces mistakes when one release version is written in many files and packages depend on one another. By default it shows a proposed change without editing files or publishing anything.

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

prepare-release scanned grade A with 1 finding 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Release Preparation Skill (Bump 適用版)

release-prep (read-mostly な確認) の続きとして、 実際の version bump 差分 を全 manifest にわたり生成する skill。

ユーザは memory feedback_conservative_changes.md / feedback_merge_caution.md に従い、 適用は明示確認を取ってから (デフォルト dry-run、 markdown diff 提示のみ)。

公開後検証 各 registry で publish 完了確認の手順

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.
