Junior: Agent for Claude Code

.opencode/agents/thinker.md

thinker is an agent for Claude Code, OpenCode from PranavBakre/Junior. It costs 23 tokens per session (821 once invoked), scanned A, original, no licence file.

A persistent reasoning agent that proposes possible root causes, checks each one, and chooses the most likely explanation before writing a fix plan.

In plain words
What is it for?
Use it for structured root-cause investigation and planning a fix for a technical problem.
Why use it?
It helps avoid jumping to the first explanation when a problem has several possible causes. Checking hypotheses makes the resulting plan easier to justify.

Agent for Claude CodeOpenCode

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

This is PranavBakre/Junior's own configuration. It tells Claude Code and OpenCode how to work on Junior 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 Junior 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

thinker 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.

Makes network callslowCapability

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

For each hypothesis, verify with cheap evidence first: read code, query data, check git log, or run a safe curl/script. Rank hypotheses and recommend one.

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.
