.opencode/agents/research-agent.md

research-agent is an agent for Claude Code, OpenCode from manti-by/demetra. It costs 14 tokens per session (378 once invoked), scanned A, original, AGPL-3.0.

An agent that checks Linear tickets against information in a wiki and on the web, then produces a research report.

In plain words
What is it for?
Use it to investigate Linear issues, compare them with internal and web sources, and summarise the findings.
Why use it?
It helps verify whether ticket details agree with supporting documentation and current external information.

Agent for Claude CodeOpenCode

Written for OpenCode and Claude Code: installed under .opencode/, but also a Claude Code subagent (agents/*.md).

This is manti-by/demetra's own configuration. It tells Claude Code and OpenCode how to work on demetra itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything demetra configures →

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

research-agent 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 3d 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.

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.
