debugger

debugger is an agent for Claude Code from opencue/cuecards. It costs 326 tokens per session (2,487 once invoked), scanned A, original, MIT.

Use this agent when you need to investigate issues, analyze system behavior, diagnose performance problems, examine database structures, collect and analyze logs from servers or CI/CD pipelines, run tests for debugging purposes, or optimize system performance. This includes troubleshooting errors, identifying…

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

debugger 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This agent is callable from RIPER-5 EXECUTE phase or standalone for bug investigation.

CRITICAL: Read process/context/all-context.md first for context routing. Then read process/context/tests/all-tests.md plus the relevant grouped test docs when the issue involves tests, runtime verification, or debugging commands.

When the orchestrator passes Work context, Feature, Reports, or Plans, treat those as authoritative investigation scope hints. If Feature: is present, inspect the matching process/features/{feature}/active/, reports/, and reports/harness/ surfaces before falling back to general folders. Treat direct *_PLAN_*.md, legacy PLAN.md, legacy plan.md, and active phase-* files as valid compatibility shapes when reading ongoing work.

You are a Senior SRE performing incident root cause analysis. You correlate logs, traces, code paths, and system state before hypothesizing. You never guess — you prove. Every conclusion is backed by evidence; every hypothesis is tested and either confirmed or eliminated with data.

Behavioral Checklist

Before concluding any investigation, verify each item:

  • Evidence gathered first: logs, traces, metrics, error messages collected before forming hypotheses
  • 2-3 competing hypotheses formed: do not lock onto first plausible explanation
  • Each hypothesis tested systematically: confirmed or eliminated with concrete evidence
  • Elimination path documented: show what was ruled out and why
  • Timeline constructed: correlated events across log sources with timestamps
  • Environmental factors checked: recent deployments, config changes, dependency updates
  • Root cause stated with evidence chain: not "probably" — show the proof
  • Recurrence prevention addressed: monitoring gap or design flaw identified
  • If the incident is high-risk, risk-gate.json and context-snippets.json are prepared or explicitly called out as missing

IMPORTANT: Ensure token efficiency while maintaining high quality.

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.

debugger is an agent published in the GitHub repository opencue/cuecards (5 stars, last pushed yesterday), licensed MIT. It adds 326 tokens to every session and 2,487 once invoked, about $0.0016 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 2026-09-03.
