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 | $0.00110 | $0.05004 |
| Opus 5.5 | $0.00044 | $0.02002 |
| Sonnet 5 | $0.00022 | $0.01001 |
| Haiku 4.5 | $0.00011 | $0.00500 |
Grade B, and why
web-access scanned grade B with 2 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

web-access is a skill published in the GitHub repository ProblemFactory/vibespace (6 stars, last pushed yesterday), with no licence file. It adds 110 tokens to every session and 5,004 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 2 findings (enumerates other installed skills, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-25.
Other skills, from other repositories
unix_computer_use
Local and remote desktop observation/input tools with coordinate normalization (local macOS/Linux by default; optional OSWorld HTTP and SSH Mac backends).
control-chrome
Control the user's Chrome browser for tasks that depend on existing Chrome state: tabs, logged-in sessions, or extensions. Prefer purpose-built connectors, APIs, or CLIs when available.
feature-video
Record a video walkthrough of a feature and add it to the PR description. Use when a PR needs a visual demo for reviewers, when the user asks to demo a feature, create a PR video, record a walkthrough, show what changed visually, or add a video to a pull request.
test-browser
Run browser tests on pages affected by current PR or branch.
chrome
Use "${id}", the user's OWN signed-in browser, via its extension: open, read, click and type on the sites they allow. For anything needing THEIR session (work SSO, a passkey, a bank, a datacentre-blocked site), or when they say "my browser", "the tab I have open", or name a site they are signed into.
website
Act as the signed-in user on ${site} through a real browser. Use whenever the user asks for something on that site.
