What it does
Network Interceptor is an agent skill from ptn1411/skill. Capture, analyze, and replay network traffic between app and license/API servers. Uses mitmproxy for capture and built-in analysis for endpoint discovery, OAuth detection, and token extraction.
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/common_api_patterns.md`, `scripts/analyze_traffic.py` and `scripts/capture_traffic.py`).
It sits in Backend & APIs, covering OAuth and OpenID Connect. The repository describes itself as: Bộ công cụ và tập hợp skill hỗ trợ phân tích phần mềm, khôi phục cấu trúc nguồn ở mức cần thiết, rà soát bảo mật, kiểm tra phụ thuộc và xây dựng kế hoạch khắc phục cho các hệ…
When your agent uses it
- Tasks that involve OAuth and OpenID Connect
Example prompts
- “/network-interceptor”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Authorization & Routing
- Capture Traffic
- Analyze Traffic
- Replay
What it can do on your machine
Read from SKILL.md and the folder at commit ce2b65e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGlobGrepBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonpip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
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
Network Interceptor loads about 589 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 53 tokens; SKILL.md has 148 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Write, Edit, Glob, Grep, Bash
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 148 words (~589 tokens).
