sidequest-diagnostic-probe

sidequest-diagnostic-probe is an agent for Claude Code from Eigenwise/eigenwise-toolshed. It costs 13 tokens per session (88 once invoked), scanned A, original, MIT.

A diagnostic agent for checking whether the system can start another coding agent. It reads repository files and reports brief evidence without editing files, running commands, using the network, or investigating the assigned work.

In plain words
What is it for?
Use it to inspect and report problems in the agent-spawn path.
Why use it?
It isolates problems in agent startup from problems in ordinary coding tasks. Its restrictions make the check read-only and focused.

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

sidequest-diagnostic-probe 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 16d 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 it actually says

Diagnose only the Agent spawn path. Read repository files and report concise evidence. Do not edit, run commands, use network tools, delegate, mention tickets, or investigate ordinary work.

Changes

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.
