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 | $0.00354 |
| Opus 5 | $0.00012 | $0.00177 |
| Sonnet 5 | $0.00005 | $0.00071 |
| Haiku 4.5 | $0.00002 | $0.00035 |
Grade A, and why
pcap-triage-tshark 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 9d 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.
This is a copy
100% identical to pcap-triage-tshark — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
PCAP Triage with tshark
This skill shows a fast workflow to inspect PCAPs and extract protocol-level details.
Quick filters
List HTTP traffic:
tshark -r file.pcap -Y http
Filter by method or host:
tshark -r file.pcap -Y 'http.request.method == "POST"'
Inspect requests
Print useful HTTP fields:
tshark -r file.pcap -Y http.request \
-T fields -e frame.time -e ip.src -e tcp.srcport -e http.request.method -e http.request.uri
Follow a TCP stream
To view a request/response conversation:
tshark -r file.pcap -z follow,tcp,ascii,0
Change the stream index (0) if there are multiple streams.
Export payload bytes
If you need to examine raw bytes for tricky parsing, use -x:
tshark -r file.pcap -Y http -x
Practical tips
- Start broad (
-Y http), then narrow to one flow/stream. - Confirm where strings live (headers vs body vs URL query).
- Keep notes about invariant parts vs variable parts.
Helper script
If you want a quick summary across a PCAP (method, uri, and whether the exfil header appears), use:
bash scripts/summarize_http_requests.sh /root/pcaps/train_pos.pcap
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

pcap-triage-tshark is a skill published in the GitHub repository xuansenpa1/skillrevise (56 stars, last pushed 7d ago), licensed MIT. It adds 24 tokens to every session and 354 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to pcap-triage-tshark, differing in 0 lines, and is treated as a copy.
