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 | $0.00049 | $0.03355 |
| Opus 5 | $0.00024 | $0.01677 |
| Sonnet 5 | $0.00010 | $0.00671 |
| Haiku 4.5 | $0.00005 | $0.00335 |
Grade E, and why
security-review scanned grade E with 4 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.
Instruction-override phrasingmediumPrompt injection
Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.
| **Goal hijack via crafted content** | #1 | High | Files in the workspace containing instruction-like text that could redirect agent behavior (e.g., `<!-- SYSTEM: ignore previous instructions -->`) | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
| **Goal hijack via crafted content** | #1 | High | Files in the workspace containing instruction-like text that could redirect agent behavior (e.g., `<!-- SYSTEM: ignore previous instructions -->`) | Downloads and executes remote codemediumSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
| **MCP server supply chain** | #4 | High | Third-party MCP servers added without source review or pinned version; `curl \| bash` install patterns | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
| **MCP server supply chain** | #4 | High | Third-party MCP servers added without source review or pinned version; `curl \| bash` install patterns | The source is not reproduced here

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.

security-review is a skill published in the GitHub repository slashwhy/super-todo (5 stars, last pushed 9d ago), with no licence file. It adds 49 tokens to every session and 3,355 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it E with 4 findings (instruction-override phrasing, hidden instructions, downloads and executes remote code). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
