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 | $0.00047 | $0.01491 |
| Opus 5 | $0.00023 | $0.00745 |
| Sonnet 5 | $0.00009 | $0.00298 |
| Haiku 4.5 | $0.00005 | $0.00149 |
Grade A, and why
cloud-bucket-brute 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Scope & authorization
Run only against organizations you own or are contractually engaged to test. This is an aggressive-3rdparty check: it does not touch the target's own infrastructure, but it fires a high volume of requests at third-party cloud providers (AWS/GCP/DigitalOcean/Alibaba/Oracle/Vultr) about the target. Expect provider-side rate-limiting and logging. Keep the candidate list scoped to the org actually in scope.
Input is the set of the target's domains. Output is any bucket name that resolves to an anonymously reachable object store.
Name permutation scheme
Turn each in-scope domain into candidate bucket names (this is the valuable part - carry it exactly):
- Reduce the domain to its registrable root label (
tldextract(...).domain, e.g.foo-bar.co.uk->foo-bar) and seed the variation set with the raw name. - If the root contains
-, split intoname+second_name, and also add the initialsname[0]+second_name[0]. - For each "common company word" that appears inside the root (
company, group, tech, solutions, international, services, world, global, ai, io, team, inc, ask, digital, data, bits, bit, open, edu, educaiton, learning, auto, stack), add the name with that word stripped out, plus the initials of the two parts around it. (Sobugcrowdyieldsbugcrowd,bug/crowdfragments,bc, etc.) - Expand every variation through the permutation templates against the suffix wordlist. Bare
{name}is always tried; multi-word templates ({name}_{word},{word}-{name},{word}_{name},{name}{word},{name}{second_name},{name}{second_name}-{word},{name}{second_name}_{word},{name}-{second_name}-{word},{name}_{second_name}_{word},{name}{second_name}{word}) are only applied to non-domain-looking single/two-part variations.
The full provider endpoint templates, per-provider fail indications, region lists, the 40-word suffix list, and the permutation templates are in references/cloud-storage-endpoints.md.
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.
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.

cloud-bucket-brute is a skill published in the GitHub repository forefy/.context (144 stars, last pushed yesterday), licensed MIT. It adds 47 tokens to every session and 1,491 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
