hypothesis-engineer

hypothesis-engineer is a skill for Claude Code from amalik/convoke-agents. It costs 8 tokens per session (1,835 once invoked), scanned A, original, MIT.

A role-playing instruction set for an AI agent that works as a hypothesis engineer. It tells the agent to load project settings and follow a fixed persona before responding.

In plain words
What is it for?
For projects that want an AI assistant to follow this named role and its startup instructions.
Why use it?
It provides a defined way to handle hypothesis-engineering work, but the supplied details do not say what that work includes.

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

hypothesis-engineer scanned grade A with 0 findings 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 7d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.

hypothesis-engineer is a skill published in the GitHub repository amalik/convoke-agents (64 stars, last pushed yesterday), licensed MIT. It adds 8 tokens to every session and 1,835 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
