write

A format guide for writing bug bounty reports that match YesWeHack's guidance. It shows how to organise a confirmed security finding.

In plain words
What is it for?
Use it to structure a report before submitting it to YesWeHack, a platform where companies receive security reports from researchers.
Why use it?
It removes guesswork about which sections to include and how to present the finding clearly.

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

write 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.

- curl — acceptable. Complete: headers, cookies, body.

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.

write is a skill published in the GitHub repository yeswehack/claude-kit (52 stars, last pushed 7d ago), licensed GPL-3.0. It adds 84 tokens to every session and 2,020 once invoked, about $0.0004 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.
