thoughtbox-team

thoughtbox-team is a skill for Claude Code from Kastalien-Research/thoughtbox. It costs 96 tokens per session (656 once invoked), scanned A, original, MIT.

A team setup that adds a background analyst to monitor a Thoughtbox reasoning session. Thoughtbox is a workspace for recording and reviewing structured reasoning.

In plain words
What is it for?
Starting an analyst teammate for substantial Thoughtbox sessions and receiving monitoring digests.
Why use it?
It can spot contradictions and ideas worth revising while a longer reasoning session is in progress.

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

thoughtbox-team 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 8d 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.

Thoughtbox Team

Spawn a 2-agent team: you (lead) + a background analyst teammate that monitors your Thoughtbox session.

When to Use

Use this when you're about to do significant Thoughtbox reasoning — sessions where you'll record 10+ thoughts and want background analysis of contradictions, evolution candidates, and session digests without having to orchestrate it yourself.

Don't use this for quick 1-3 thought sessions — the coordination overhead isn't worth it.

How to Spawn

Tell Codex you want to create a team. The analyst teammate should be configured with:

  • Name: analyst
  • Role: Read the agent definition at .Codex/agents/thoughtbox-analyst.md and use it as the teammate's instructions
  • Model: Haiku (cost-efficient for background monitoring)
  • Focus: Monitor the Thoughtbox session specified by $ARGUMENTS, or the most recent active session

Example spawn prompt:

Create an agent team with one teammate:
- Name: analyst
- Instructions: [contents of .Codex/agents/thoughtbox-analyst.md]
- Task: Monitor Thoughtbox session [SESSION_ID] for evolution candidates and contradictions. Message me when you find thoughts that should be revised. Generate a digest every 20 thoughts.

Working with the Analyst

Once the team is running:

  1. Do your work normally. Record thoughts via thoughtbox_execute as usual.
  2. Watch for messages. The analyst will message you when it finds evolution candidates.
  3. Respond to evolution signals. When the analyst says "Thought 55 may contradict thoughts 5, 24", you decide whether to revise.
  4. Request digests. Message the analyst: "Give me a digest of where we are."

What the Analyst Does

  • Periodically checks the session for new thoughts
  • Runs deterministic evolution candidate detection (word overlap, structural heuristics)
  • Flags assumption_update and decision_frame thoughts for special attention
  • Generates compressed digests at milestones (~every 20 thoughts)
  • Messages you with concise, actionable findings

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.
