debugger-driven-analysis

debugger-driven-analysis is a skill for Claude Code, Codex from mattmre/EVOKORE-MCP-PUBLIC. It costs 41 tokens per session (524 once invoked), scanned A, original, MIT.

A workflow for investigating program behavior while it is running with a debugger. It combines breakpoints, register and memory observations, and static code analysis to answer specific questions about a binary.

In plain words
What is it for?
Use it to plan debugger sessions for Windows or low-level binaries, inspect function arguments and memory changes, follow important branches, and feed confirmed findings back into code names and notes.
Why use it?
Some behavior cannot be confirmed by reading code alone, especially unpacking, decoded data, branch conditions, and environment checks. Runtime evidence can show what the program actually does.

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-driven-analysis 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.

What it actually says

Debugger-Driven Analysis

Use runtime evidence to resolve questions that static analysis cannot answer cleanly: unpacking, argument decoding, branch conditions, environment checks, IPC, crypto state, and anti-analysis behavior.

Workflow

  1. Start from a concrete question, not "debug everything."
  2. Choose the debugger mode:
    • x64dbg for Windows user-mode binaries
    • WinDbg for deeper Windows/system scenarios
    • pwndbg-like workflows for low-level register/stack discipline
  3. Set a minimal breakpoint plan:
    • process entry / unpacking point
    • suspicious imported APIs
    • target functions identified in static recon
    • memory write / allocation pivots when needed
  4. Capture:
    • arguments and calling convention state
    • register snapshots before/after call
    • buffers, decoded strings, and memory changes
    • control-flow decisions at critical branches
  5. Feed confirmed runtime facts back into static naming, signatures, and comments.

Tool Families to Prefer

  • binary_analysis_*x64dbg*
  • binary_analysis_*windbg*
  • binary_analysis_*session*
  • binary_analysis_*report*

If the exact prefixed names are unclear, use discover_tools with x64dbg debugger winDbg reverse engineering.

Debugger Heuristics

  1. Break on semantic pivots, not every instruction.
  2. Snapshot before patching or forcing branches.
  3. Record the minimum evidence needed to answer the current hypothesis.
  4. Correlate every important dynamic observation to a static function or address.

Deliverable Format

  • Question being tested
  • Breakpoints and why they were chosen
  • Runtime observations
  • Static addresses/functions updated from those observations
  • Recommended next action

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-driven-analysis is a skill published in the GitHub repository mattmre/EVOKORE-MCP-PUBLIC (3 stars, last pushed 3mo ago), licensed MIT. It adds 41 tokens to every session and 524 once invoked, about $0.0002 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.
