bug-court

bug-court is a skill for Claude Code from romiluz13/cc-teams. It costs 26 tokens per session (4,308 once invoked), scanned A, original, MIT.

A debugging process where several investigators test competing explanations for a bug, then compare the evidence to identify the root cause.

In plain words
What is it for?
Use it for difficult bugs that have multiple plausible causes, with separate investigation, debate, implementation, review, and end-to-end verification stages.
Why use it?
It reduces the risk of applying a quick fix to a symptom while leaving the underlying problem in place.

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

bug-court 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 7d 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.

Bug Court Protocol

Overview

Bug Court replaces single-threaded debugging with competing hypotheses. Multiple investigators each champion a different root cause hypothesis, gather evidence, then debate each other. The hypothesis that survives cross-examination wins.

Core principle: ALWAYS find root cause before attempting fixes. Symptom fixes are failure.

Violating the letter of this process is violating the spirit of debugging.


The Iron Law

NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST

If you haven't completed Phase 1, you cannot propose fixes.


Team Composition

Teammate Role Mode
investigator-1 through investigator-N Hypothesis champion READ-ONLY (gather evidence, run tests, NO source edits)
builder (Phase 5 only) Fix implementer READ+WRITE (implements the winning fix)
security-reviewer (Phase 6) Security review of fix READ-ONLY
performance-reviewer (Phase 6) Performance review of fix READ-ONLY
quality-reviewer (Phase 6) Quality review of fix READ-ONLY
verifier (Phase 7) E2E verification of fix READ-ONLY

CRITICAL: Investigators are READ-ONLY. They gather evidence and run diagnostic commands but do NOT edit source code. Only the builder (spawned after verdict) implements the fix. This prevents file conflicts between parallel investigators.

Number of investigators = number of plausible hypotheses (typically 2-5).

Activation Strategy (Agent Teams-Native)

Use phase-scoped activation for cleaner debugging flow:

  1. Team kickoff: spawn only investigator-* roles for current hypotheses.
  2. Spawn builder only after debate verdict confirms root cause.
  3. Spawn review triad only after fix task is runnable.
  4. Spawn verifier only after challenge round task is runnable.

Do not pre-spawn downstream roles before their phase.


Protocol Phases

Phase 1: Hypothesis Generation (Lead)

Before spawning investigators, the lead generates hypotheses:

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.

bug-court is a skill published in the GitHub repository romiluz13/cc-teams (5 stars, last pushed 5mo ago), licensed MIT. It adds 26 tokens to every session and 4,308 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
