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 | $0.00076 | $0.08535 |
| Opus 5 | $0.00038 | $0.04267 |
| Sonnet 5 | $0.00015 | $0.01707 |
| Haiku 4.5 | $0.00008 | $0.00853 |
Grade C, and why
convex-expert scanned grade C 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 6d 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

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.

convex-expert is a skill published in the GitHub repository get-convex/convex-codex-plugin (5 stars, last pushed 8d ago), with no licence file. It adds 76 tokens to every session and 8,535 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 2 findings (hidden instructions, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
