What it does

Upstream Fix And Pin is an agent skill from mizchi/skills. 自分の依存ライブラリにバグや欠けている機能があり、上流に PR を出して取り込まれるまで下流プロジェクトを動かしたいときの運用。git ref pin（branch HEAD SHA → merge SHA）、link: への退避判断、SHA 取り扱い、pnpm v10 の build script gating まで含む。

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).

It sits in Development, covering Git workflow. It works with pnpm, Git, npm and GitHub. The repository describes itself as: Agent skills by mizchi, distributed via APM.

When your agent uses it

  • Tasks that involve Git workflow

Example prompts

  • “/upstream-fix-and-pin”

Requirements

  • Node.js

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. dist/ を git track（tsc 出力など）。.gitignore から外して commit。.gitattributes で dist/** linguist-generated=true と -diff を付けておくと PR レビュー時に diff が爆発しない。
  2. （補助）"prepare": "tsc" を package.json に追加。npm install 経由なら走る。pnpm git ref では allowlist が要るので user 動線が増える点はトレードオフ。

What it can do on your machine

Read from SKILL.md and the folder at commit 62f5808. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git
    • pnpm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • codeload.github.com
    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Upstream Fix And Pin loads about 1k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 340 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 340 words (~1,012 tokens).
