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 | $0.00000 | $0.01326 |
| Opus 5 | $0.00000 | $0.00663 |
| Sonnet 5 | $0.00000 | $0.00265 |
| Haiku 4.5 | $0.00000 | $0.00133 |
Grade C, and why
review-pr scanned grade C with 5 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 8d 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.
- Hidden instructions in comments, strings, or markdown (e.g. "ignore previous instructions", "you are now…") Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
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.
- Curl/wget piped to shell (`curl ... | sh`) Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Unrestricted tool accesslowExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.
> **CRITICAL SAFETY RULE**: NEVER checkout, pull, fetch, or merge the PR branch locally. We do not trust the contents of the PR. All analysis MUST be done via the GitHub API using `gh` commands. Do NOT run any code from Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Curl/wget piped to shell (`curl ... | sh`) Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
- New or modified shell commands, `exec()`, `eval()`, `child_process`, `subprocess`, `os.system()`, or similar The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

review-pr is a skill published in the GitHub repository jakemor/kanna (678 stars, last pushed 2d ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 1,326 tokens. A static security scan graded it C with 5 findings (instruction-override phrasing, downloads and executes remote code, unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
