GitHub Actions Supply Chain Pinning
asyncapi/generator
A skill your agent uses when editing, adding, or reviewing any file under .github/workflows/, or when a CI step installs a CLI tool (npm i -g, npx, pipx, uses: /setup-).
Run snapshot regression tests after changes to OPA rules, scanners, analyzers, or formatters to detect output regressions.

What it does
Snapshot is an agent skill from boostsecurityio/poutine. Run snapshot regression tests after changes to OPA rules, scanners, analyzers, or formatters to detect output regressions.
Its SKILL.md is about 210 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Supply chain security, Linting and formatting and Vulnerability scanning. It works with GitHub, GitHub Actions and Go. The repository describes itself as: poutine, a supply chain vulnerability scanner for build pipelines. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Supply chain security
- Tasks that involve Linting and formatting
- Tasks that involve Vulnerability scanning
Example prompts
- “/snapshot”
Requirements
- Pre-approved tools (allowed-tools): Bash(make snapshot:*), Bash(make update-snapshots:*)
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Run snapshot tests: make snapshot
- If tests fail, examine the diff carefully
- After updating snapshots, re-run make snapshot to confirm they pass
- Report which snapshots changed and why
What it can do on your machine
Read from SKILL.md and the folder at commit 0f4aa19. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(make snapshot:*)Bash(make update-snapshots:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
make
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
GH_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Snapshot loads about 214 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 84 words of instructions outside code blocks.
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.

Run the snapshot regression tests to validate analysis output hasn't changed:
- Run snapshot tests:
make snapshot - If tests fail, examine the diff carefully:
- If the change is expected (new rule, modified output format, updated OPA policy), update the snapshots:
make update-snapshots - If the change is unexpected, investigate what caused the regression and fix the root cause
- If the change is expected (new rule, modified output format, updated OPA policy), update the snapshots:
- After updating snapshots, re-run
make snapshotto confirm they pass - Report which snapshots changed and why
Note: Requires GH_TOKEN environment variable to be set.

Questions about Snapshot
What does Snapshot do?
Run snapshot regression tests after changes to OPA rules, scanners, analyzers, or formatters to detect output regressions. Snapshot is an agent skill from boostsecurityio/poutine. Run snapshot regression tests after changes to OPA rules, scanners, analyzers, or formatters to detect output regressions.
When should I use Snapshot?
Snapshot fits situations like: tasks that involve Supply chain security; tasks that involve Linting and formatting; tasks that involve Vulnerability scanning.
How do I install Snapshot in Claude Code?
Run `npx skills add boostsecurityio/poutine --skill snapshot -a claude-code`. Or copy the skill folder (.claude/skills/snapshot in boostsecurityio/poutine) into .claude/skills/snapshot in your project. Claude Code loads it when a task matches its description.
How do I install Snapshot in Codex?
Run `npx skills add boostsecurityio/poutine --skill snapshot -a codex`. Or copy the skill folder (.claude/skills/snapshot in boostsecurityio/poutine) into .agents/skills/snapshot in your project. Codex loads it when a task matches its description.
Can I use Snapshot in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add boostsecurityio/poutine --skill snapshot -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/snapshot, .gemini/skills/snapshot, .github/skills/snapshot and .opencode/skills/snapshot in your project.
What does Snapshot need to run?
Going by SKILL.md and its folder, Snapshot needs the command-line tools its instructions call (make) and credentials named GH_TOKEN. Its frontmatter pre-approves these tools: Bash(make snapshot:*), Bash(make update-snapshots:*).
Does Snapshot access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Snapshot safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Snapshot use?
Snapshot is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Snapshot use?
About 214 tokens (SKILL.md is roughly 856 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Snapshot?
Skills that share tags, products or a category with Snapshot: GitHub Actions Supply Chain Pinning (asyncapi/generator, 1.1k stars), Warp Vulnerability Triage (warpdotdev/warp, 65k stars), Renovate Actions PR Review (backnotprop/plannotator, 9.2k stars) and Golang Continuous Integration (samber/cc-skills-golang, 3.4k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
