agent-skills

A set of reusable instructions that teaches an AI assistant how to use Argos, a service for visual checks of web application changes.

In plain words
What is it for?
Use it to run the Argos command line tool, review pull-request snapshots, upload screenshots or recordings, and read human comments.
Why use it?
It gives the assistant the commands and review process needed to inspect visual test results and share evidence in pull requests.

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.

Per session 32 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 494 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

agent-skills 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 2d 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.

The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent skills

Argos publishes agent skills — reusable instruction packs your AI assistant loads to perform Argos tasks reliably, without you writing long prompts. They work with assistants that support skills, such as Claude Code, Codex, and Cursor.

Available skills

Skill What it teaches the agent
argos-cli The Argos CLI: commands, flags, authentication rules, and output formats.
argos-pr-review A complete pull-request visual review workflow: find the Argos build, inspect snapshots, summarize changes, and approve or request changes.
argos-upload When and how to share a screenshot or a screen recording by link, how to embed it so a pull request actually renders it, and how to read back the comments a human pinned on it.

Installation

npx skills add https://argos-ci.com

This installs every skill Argos publishes. The skill content lives in the argos-javascript repository.

Usage

Reference a skill in your prompt to activate it:

Use $argos-pr-review to review this pull request with its Argos build.
https://github.com/acme/app/pull/123

For the full workflow — tokens to set, what the agent does, and how to phrase prompts when your assistant does not support skills — see Review builds with AI agents.

The argos-cli skill also covers the flakiness commands, so an agent can investigate an unstable test and silence a change it can't fix — see Fix flaky tests with AI agents.

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.

agent-skills is an agent published in the GitHub repository argos-ci/docs (5 stars, last pushed 15d ago), licensed MIT. It adds 32 tokens to every session and 494 once invoked, about $0.0002 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.
