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 | $0.00067 | $0.01384 |
| Opus 5.5 | $0.00027 | $0.00554 |
| Sonnet 5.5 | $0.00013 | $0.00277 |
| Haiku 4.5 | $0.00007 | $0.00138 |
Grade A, and why
gha-sha-reference 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 2mo 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.

GitHub Actions SHA Reference Skill
目的
このスキルはGitHub Actionsワークフローファイル内のuses:フィールドで使用されているタグ参照（例: @v4）を、セキュリティのベストプラクティスに従ってSHA参照（例: @11bd71901bbe5b1630ceea73d27597364c9af683 # v4.2.2）に自動変換します。
使用タイミング
以下の場合にこのスキルを発動してください：
- ユーザーが「GitHub ActionsをSHA参照に変換して」と要求したとき
- ユーザーが「actionsのusesをSHAに書き換えて」と言及したとき
実行手順
1. 変更対象を確認
まず --check --diff オプションで、どのファイルが変更されるかを確認します：
pinact run --check --diff
出力例:
ERROR action isn't pinned
.github/workflows/ci.yaml:10
- uses: actions/checkout@v4
+ uses: actions/checkout@08eba0b27e820071cde6df949e0beb9ba4906955 # v4.3.0
ERROR action isn't pinned
.github/workflows/ci.yaml:11
- - uses: actions/setup-go@v4
+ - uses: actions/setup-go@4d34df0c2316fe8122ab82dc22947d607c0c91f9 # v4.0.0
ERROR action isn't pinned
.github/workflows/deploy.yaml:15
- uses: actions/checkout@v4
+ uses: actions/checkout@08eba0b27e820071cde6df949e0beb9ba4906955 # v4.3.0
2. 変換を実行
確認後、pinact run を実行してすべての対象ファイルを一括変換します：
pinact run
pinactは以下を自動的に行います：
- タグ参照からコミットSHAを取得
- 最も詳細なバージョンタグ（v4.3.0など）をコメントとして追加
.github/workflows/*.{yml,yaml}とaction.{yml,yaml}を自動検出して変換
実装例
例1: 基本的な使用方法
ステップ1: 変更対象を確認:
pinact run --check --diff
出力:
ERROR action isn't pinned
.github/workflows/ci.yaml:10
- uses: actions/checkout@v4
+ uses: actions/checkout@08eba0b27e820071cde6df949e0beb9ba4906955 # v4.3.0
ERROR action isn't pinned
.github/workflows/ci.yaml:11
- - uses: actions/setup-go@v4
+ - uses: actions/setup-go@4d34df0c2316fe8122ab82dc22947d607c0c91f9 # v4.0.0
ステップ2: 変換を実行:
pinact run
変換後のワークフローファイル (.github/workflows/ci.yaml):
name: CI
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@08eba0b27e820071cde6df949e0beb9ba4906955 # v4.3.0
- uses: actions/setup-go@4d34df0c2316fe8122ab82dc22947d607c0c91f9 # v4.0.0
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.

gha-sha-reference is a skill published in the GitHub repository syou6162/agent-skills (11 stars, last pushed 4mo ago), licensed MIT. It adds 67 tokens to every session and 1,384 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-30.
