What it does
Web Recon is an agent skill from NeoTheCapt/RedteamAgent. Enumerate web technologies, headers, endpoints, and metadata from a target
Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Bug bounty and Penetration testing. The repository describes itself as: An AI red-team agent for authorized labs and web app pentesting workflows. Turns Claude Code / OpenCode / Codex into a structured recon → test → exploit → report workflow, with…
When your agent uses it
- Tasks that involve Bug bounty
- Tasks that involve Penetration testing
Example prompts
- “/web-recon”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- HTTP Header Analysis
- Technology Fingerprinting
- CMS Detection
- SSL/TLS Analysis
- Well-Known Files
- JS File Extraction (surface-level — deep analysis is source-analyzer's job)
- HTML Source (surface-level — deep analysis is source-analyzer's job)
What it can do on your machine
Read from SKILL.md and the folder at commit 2e60476. 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
Shell commands in SKILL.md call:
openssl
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
Web Recon loads about 770 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 103 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); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 103 words (~770 tokens).
