supervisor

supervisor is an agent for coding agents from beettlle/pi-spine. It costs 16 tokens per session (50 once invoked), scanned C, original, MIT.

A batch supervisor that watches coordinated agent work and responds to failures while keeping the operator informed.

In plain words
What is it for?
Use it to supervise batches of agent tasks, manage failures, and provide status updates to the person overseeing the run.
Why use it?
It helps detect and handle problems during multi-agent task runs instead of leaving failures unnoticed.

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 C, and why

supervisor scanned grade C 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 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

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.
