exploit

A penetration-testing workflow for investigating and proving web-application vulnerabilities. It covers issues such as SQL injection, cross-site scripting, broken access controls, token problems, and unsafe file handling.

In plain words
What is it for?
It is for testing attack techniques against authorised targets, using findings from reconnaissance and secret searches, and documenting evidence for confirmed vulnerabilities.
Why use it?
It provides a structured way to test suspected weaknesses and requires direct evidence before describing a security issue as confirmed or severe.

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.

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

exploit 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Exploitation Phase

Philosophy

Every confirmed finding must have a direct evidence quote from the actual response. Never claim Critical without proving the full kill chain: access -> escalation -> data. Never skip a technique because "it probably won't work" - the manifest decides what runs. WAF presence means bypass first, then exploit - never give up at the first 403.

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.

exploit is a skill published in the GitHub repository kalpmodi/akira (21 stars, last pushed 1mo ago), licensed MIT. It adds 128 tokens to every session and 3,616 once invoked, about $0.0006 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.
