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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00131 | $0.04898 |
| Opus 5.5 | $0.00052 | $0.01959 |
| Sonnet 5.5 | $0.00026 | $0.00980 |
| Haiku 4.5 | $0.00013 | $0.00490 |
Grade A, and why
e2e-reviewer 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
E2E Test Scenario Quality Review
Review Playwright/Cypress E2E specs and POMs using the scanner and semantic checks below.
Reference:

- Cypress best practices: https://docs.cypress.io/app/core-concepts/best-practices
Fetching references with tools: reference text already in your context is complete — apply all of it and do not fetch it again. A complete reference from the current loaded skill copy stays in context for this review; reuse it across scan roots and Phase 2 candidates without fetching it again. Reuse does not skip any required scan, confirmation, or semantic sweep. If the skill copy changes or the text is missing, truncated, or lost after compaction, read the required reference again before using it. When you do fetch files, some hosts show only the head and tail of a large tool result, and parallel calls in one step share that limit. Keep each step's combined tool output under about 30 KB: batch small reads (references, specs, POMs, and configs) into one tool call up to that size, and read a larger file alone. Bound searches and listings of the repository under review the same way: narrow the path or glob, or cap the output (for example | head -c 30000). Fetch references/semantic-review.md (about 30 KB) in a tool call of its own, never batched with reporting.md, verification-rules.md, or any other file, and fetch pattern contracts from the per-pattern files that § Pattern Reference names. If a tool result carries a truncation or omission notice, re-read the omitted range before relying on it.
Reading the repository under review: locate first, then read only what you need, copying these forms:
rg -l '<pattern>' <dir> # which files mention it
rg -n -C 3 '<pattern>' <file> # where, in one file
nl -ba <file> | sed -n '<a>,<b>p' # one range of at most 250 lines
Batch several small files or ranges into one command while their combined output stays under about 30 KB, and split larger reads across commands: on some hosts, output beyond that is cut in the middle, and each extra command re-sends the whole conversation.
What ships with it
60 files 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.

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.

e2e-reviewer is a skill published in the GitHub repository voidmatcha/e2e-skills (23 stars, last pushed yesterday), licensed Apache-2.0. It adds 131 tokens to every session and 4,898 once invoked, about $0.0005 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 2026-08-31.
