source-analysis

A guide for examining frontend source code to find hidden web addresses, API endpoints, and exposed secrets.

In plain words
What is it for?
Use it to inspect frontend files for undisclosed routes, backend interfaces, and accidentally included keys or credentials.
Why use it?
It helps reveal parts of a web application that are not visible in its normal pages and may need security review.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

source-analysis 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 yesterday.

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.

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.

source-analysis is a skill published in the GitHub repository NeoTheCapt/RedteamAgent (122 stars, last pushed 1mo ago), with no licence file. It adds 16 tokens to every session and 2,591 once invoked, about $0.0001 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.
