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 | $0.00024 | $0.00373 |
| Opus 5 | $0.00012 | $0.00187 |
| Sonnet 5 | $0.00005 | $0.00075 |
| Haiku 4.5 | $0.00002 | $0.00037 |
Grade A, and why
traffic-proxy 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 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.
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
traffic-proxy
Use this skill when automated scans find a suspicious workflow but proof needs manual request mutation.
Core tools
- mitmproxy / mitmdump: lightweight CLI interception and Python scripting.
- zaproxy / zap-cli: baseline active checks + scripting-friendly automation.
When to use
- Session/auth workflow inconsistencies (invite, verify-otp, role change, checkout flow).
- Business logic checks where endpoint order/state matters.
- Header trust-boundary testing (custom auth blobs, forwarded headers, rewrite headers).
Safe execution guidance
- Run proxies only on authorized targets and in scoped windows.
- Start with read-only capture before mutation.
- Keep request rate low under WAF/rate-limit pressure.
- Prefer replaying one request class at a time with strict evidence notes.
mitmproxy quick patterns
- Capture mode:
mitmdump --listen-host 127.0.0.1 --listen-port 8081 --set flow_detail=1 - Save flows:
mitmdump -w reports/output/<target>/mitm.flow - Replay selected flow IDs after controlled modifications.
ZAP quick patterns
- Quick baseline:
zaproxy -cmd -quickurl https://<target> -quickprogress - Scripted run:
zap-cli quick-scan --self-contained --spider https://<target> - Use constrained scans first; avoid broad active scans until recon confidence is high.
Evidence contract
For each proxy-assisted finding, capture:
- Original request and response
- Mutated request and response
- Boundary violated (auth, role, object ownership, state transition)
- Reproducible minimal steps
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.

traffic-proxy is a skill published in the GitHub repository Roshu18/bearstrike-ai (4 stars, last pushed 5mo ago), licensed MIT. It adds 24 tokens to every session and 373 once invoked, about $0.0001 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.
