Recon Skills is a pack of security-testing skills covering reconnaissance, web applications, APIs, authentication, vulnerability validation, cloud infrastructure, and reporting. Security professionals use it for authorized assessments of systems they own or have written permission to test. The catalogue entries are individual skills from the pack.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00900 | $0.00900 |
| Opus 5 | $0.00450 | $0.00450 |
| Sonnet 5 | $0.00180 | $0.00180 |
| Haiku 4.5 | $0.00090 | $0.00090 |
Grade A, and why
recon-skills AGENTS.md scanned grade A with 1 finding 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 5d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Use normal command names such as `curl`, `nmap`, or `python3`. How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Library Contributor Guide
This repository contains portable offensive-security playbooks. It does not configure or document the runtime that consumes them.
These skills are for authorized security testing only. Only test targets you own or have explicit written permission to test.
Scope
Add or maintain skills for:
- external asset discovery and OSINT;
- web, API, cloud, identity, and infrastructure testing;
- platform-specific vulnerability validation;
- attack-path analysis;
- evidence handling, triage, and reporting.
Do not add:
- agent framework configuration;
- model or provider selection;
- chat, dashboard, cron, or scheduler instructions;
- private container, host, SSH, or network topology;
- deployment-specific workarounds;
- target-specific evidence or credentials;
- unrelated productivity or creative automation.
Docker, SSH, controllers, workers, and similar terms are valid when they are the subject of a security technique. They are not valid as assumptions about where this repository is running.

Skill Contract
Every new or substantially revised SKILL.md must follow STYLE.md
and include:
When to UsePrerequisitesHow to RunProcedurePitfallsVerification
Frontmatter must provide a unique kebab-case name, a concise description,
semantic version, license, supported platforms, category, tags, and valid
related-skill names.
Commands must be runnable, bounded, and explicit about side effects. Include timeouts and conservative concurrency. Distinguish discovery from validation, and require operator confirmation before any state-changing request.
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.

recon-skills AGENTS.md is an instructions file published in the GitHub repository uphiago/recon-skills (1,228 stars, last pushed 3d ago), licensed MIT. It adds 900 tokens to every session, about $0.0045 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
