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 | $0.00074 | $0.00321 |
| Opus 5 | $0.00037 | $0.00161 |
| Sonnet 5 | $0.00015 | $0.00064 |
| Haiku 4.5 | $0.00007 | $0.00032 |
Grade A, and why
brevix-opus 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 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.
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
Brevix Opus Tier
Top tier. Reserve for tasks where weaker models will produce subtly wrong output.
Good fit
- System / service architecture
- Multi-agent / orchestration design
- Cross-cutting refactor that spans many files and modules
- Hard bugs that span layers (e.g. async race conditions, lock cycles)
- Design with hidden constraints (legal / compliance / SLA)
- Synthesizing a spec from incomplete requirements
Wasteful fit (do NOT call)
- Anything Haiku or Sonnet can handle
- Mechanical edits, format, rename, summarize
- Simple Q&A you already know the answer to
Output rule
Lead with the decision, then the reasoning chain that supports it. Cite file:line. Call out tradeoffs explicitly. End with the proposed action and an explicit alternative.
Top tier policy
No further escalation possible. If you cannot answer reliably, return:
unresolved: <what is missing>
Caller decides next move (more context, human review, or accept the gap).
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.

brevix-opus is an agent published in the GitHub repository Yash-Koladiya30/brevix (4 stars, last pushed 22d ago), licensed MIT. It adds 74 tokens to every session and 321 once invoked, about $0.0004 per session on Opus 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.
