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 | $0.00109 | $0.03698 |
| Opus 5.5 | $0.00044 | $0.01479 |
| Sonnet 5.5 | $0.00022 | $0.00740 |
| Haiku 4.5 | $0.00011 | $0.00370 |
Grade A, and why
basket scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
`curl` unless the user specifically wants the API. How it starts
The opening of the file, as written. The whole thing — 325 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Basket — grocery price comparison
Compares a whole basket, not individual items. Cheapest-per-item is a lookup; cheapest-basket is arithmetic nobody does by hand, and it frequently flips the answer — a platform wins on two items and loses on the other ten.
Every price is fetched live from the platform at run time. Nothing is hardcoded — no price list, no pack table, no fee table. When the tool doesn't know a number it says so instead of supplying a plausible one. Preserve that when you relay results: don't fill gaps with your own estimates.
Before anything else: check the environment
Every search runs as a real webcmd command against a browser webcmd owns.
basket doctor
That checks Node, webcmd, the browser bridge, the four adapters, and the data directory — and prints a fix under anything that fails. Run it first whenever something looks wrong; it is faster than reading errors from a failed run.
If it reports problems, basket setup fixes most of them non-interactively
(clears the stale cloak lock, regenerates adapters) and then walks the user
through setting delivery locations.
Two failure modes worth recognising by name, because webcmd's own messages don't spell them out:
- "profile is already in use by another instance of Chromium" — an orphaned
cloak browser holds a lock on
~/.webcmd/cloak/profiles/default.basket setupclears it, or kill*cloakbrowser*processes and removeSingleton{Lock,Cookie,Socket}from that directory. fetch failedon first run — cloak is downloading ~150 MB of Chromium into~/.cloakbrowser/. Needs network and patience, not debugging.
Delivery location lives in the webcmd browser profile. Set it once per
platform by hand and it persists (siteSession: 'persistent' keeps it alive
across commands). If a platform returns "results never rendered", the location
is missing — fix it in the browser, don't debug the adapter:
WEBCMD_WINDOW=foreground \
printf 'await page.goto("https://www.bigbasket.com/");' \
| webcmd browser setloc run --stdin
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.

basket is a skill published in the GitHub repository aizen2006/comparebasket (0 stars, last pushed 2mo ago), licensed MIT. It adds 109 tokens to every session and 3,698 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
