What it does
Pcap Triage Tshark is an agent skill from benchflow-ai/skillsbench. Fast workflow to inspect PCAPs and extract protocol-level details using tshark
Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/summarize_http_requests.sh`).
It sits in Security. It works with Wireshark. The repository describes itself as: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is Apache-2.0.
When your agent uses it
- Security work in your project
Example prompts
- “/pcap-triage-tshark”
Requirements
- A Bash shell
What it can do on your machine
Read from SKILL.md and the folder at commit 9a1f4dd. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
bash
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Pcap Triage Tshark loads about 328 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 116 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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 httpFilter 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.uriFollow a TCP stream
To view a request/response conversation:
tshark -r file.pcap -z follow,tcp,ascii,0Change 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 -xPractical 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© benchflow-ai, Apache-2.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file
