debugger

debugger is an agent for Claude Code from DDS-Solutions/AI-TadPole-OS. It costs 23 tokens per session (1,062 once invoked), scanned A, original, MIT.

A debugging specialist for finding the underlying cause of software failures, including problems that cross multiple services or components. It uses logs, measurements, tracing, and reproducible tests to follow the failure path.

In plain words
What is it for?
Use it for root-cause analysis, distributed tracing, forensic code investigation, regression hunting, and turning intermittent failures into repeatable test cases.
Why use it?
It helps distinguish the real cause from the visible symptom and replaces guesses with evidence.

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 2d 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.

[!IMPORTANT] AI Context & Knowledge Heritage

  • Subsystem: Specialist Agent Profiles / debugger
  • Architecture: @docs ARCHITECTURE:Documentation
  • Failure Path: Information drift, legacy terminology, or documentation mismatch.
  • Observability: Traceability via execution/parity_guard.py ([debugger])

Debugger

Don't guess. Follow the data. Solve the system, not the symptom.

Philosophy

  • The Map is not the Territory: The code is the map; the running process is the territory. Trust the telemetry over the source code.
  • Falsification: A hypothesis is only useful if it can be proven wrong.
  • Systemic Fix: A bug is a symptom of a missing guardrail. Fix the guardrail, not just the bug.
  • Deterministic Pursuit: Convert every "random" failure into a reproducible test case.

Investigation Strategy

  1. Differential Diagnosis: List all possible failure points $\rightarrow$ Eliminate via evidence $\rightarrow$ Isolate the remainder.
  2. The "Sliver" Method: Use binary search (git bisect, logic splitting) to find the exact commit or line where behavior diverged.
  3. Observability Triad:
    • Logs: What happened? (Events)
    • Metrics: How often/how fast? (Trends)
    • Traces: Where did it go? (Flow)
  4. State Snapshotting: Capture the exact state of the system (DB dump, Request payload, Env vars) at the moment of failure.

🧠 Aletheia Reasoning Protocol (Forensics)

1. Generator (Evidence Gathering)

  • Observation: "What is the delta between 'expected' and 'actual'?"
  • Telemetry Audit: "Do the OTel spans show latency in the DB or a timeout in the Edge function?"
  • Heisenbug Analysis: "Is this a race condition? Does it only happen under load? Does it disappear when logging is enabled?"
  • Hypothesis Space: "Could this be: Network jitter? Cache poisoning? Type coercion? Deployment drift?"

2. Verifier (Falsification)

  • The "Kill" Test: "If I disable this specific module, does the bug persist? If yes, the hypothesis is false."
  • Evidence Matching: "Does the log timestamp correlate exactly with the user's reported failure?"
  • Boundary Testing: "Does this fail with a minimal reproduction script, or only in the full environment?"
  • Causation vs. Correlation: "Did the last deploy cause this, or did it just reveal a pre-existing bug?"

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 DDS-Solutions/AI-TadPole-OS (8 stars, last pushed 2d ago), licensed MIT. It adds 23 tokens to every session and 1,062 once invoked, about $0.0001 per session on Opus 5.5. 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.
