ux-grill

ux-grill is a skill for Claude Code, Codex from Kanevry/session-orchestrator. It costs 125 tokens per session (455 once invoked), scanned A, original, MIT.

A repeatable audit for a running web app's user experience across its routes and screen sizes. It checks accessibility rules, touch-target size, horizontal overflow, page titles, scripted user journeys, and screenshots.

In plain words
What is it for?
Use it to inspect a web app route by route and viewport by viewport, then review screenshot-based findings with two user profiles.
Why use it?
It replaces an informal visual check with the same mechanical checks and questions each time. This helps reveal accessibility, layout, and journey problems that may be missed by looking at one page.

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

ux-grill 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 1mo 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.

What it actually says

ux-grill

Portable mirror — generated, do not edit. The canonical workflow lives at skills/ux-grill/SKILL.md; read that file for the full instructions. This mirror carries only agentskills.io-spec-legal frontmatter so harnesses that discover skills under .agents/skills/ can find and route to the skill.

Regenerate with node scripts/generate-agents-skills.mjs.

Read the linked document in full and follow its complete workflow, including prechecks and stop conditions. Resolve its link relative to this SKILL.md, not the project working directory. The plugin root is three directories above this file. Resolve package paths such as skills/ and scripts/ from that root and relative links in the canonical document from its own directory. Keep the user’s project as the target of project operations.

$ARGUMENTS means the trailing user input after the selected command skill, or an empty string when absent. Preserve flags, quoted text, and Unicode as data. Do not perform global substitution in the command document, shell expansion on the argument string, or execution of that string as shell code. Pass command arguments through structured tool parameters or safely quoted individual arguments.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
