What it does
Gdb CLI is an agent skill from sickn33/agentic-awesome-skills. GDB debugging assistant for AI agents - analyze core dumps, debug live processes, investigate crashes and deadlocks with source code correlation
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Debugging. It works with Python. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Tasks that involve Debugging
Example prompts
- “/gdb-cli”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 1e53ce2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pipnode
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
github.com
Also links to:
pypi.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Gdb CLI loads about 1.4k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 397 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

GDB Debugging Assistant
Overview
A GDB debugging skill designed for AI agents. Combines source code analysis with runtime state inspection using gdb-cli to provide intelligent debugging assistance for C/C++ programs.
When to Use This Skill
- Analyze core dumps or crash dumps
- Debug running processes with GDB attach
- Investigate crashes, deadlocks, or memory issues
- Get intelligent debugging assistance with source code context
- Debug multi-threaded applications
Do Not Use This Skill When
- The task is unrelated to C/C++ debugging
- The user needs general-purpose assistance without debugging
- No GDB is available (GDB 9.0+ with Python support required)
Prerequisites
# Install gdb-cli
pip install gdb-cli
# Or from GitHub
pip install git+https://github.com/Cerdore/gdb-cli.git
# Verify GDB has Python support
gdb -nx -q -batch -ex "python print('OK')"Requirements:
- Python 3.6.8+
- GDB 9.0+ with Python support enabled
- Linux OS
How It Works
Step 1: Initialize Debug Session
For core dump analysis:
gdb-cli load --binary <binary_path> --core <core_path> [--gdb-path <gdb_path>]For live process debugging:
gdb-cli attach --pid <pid> [--binary <binary_path>]Output: A session_id like "session_id": "a1b2c3". Store this for subsequent commands.
Step 2: Gather Initial Information
SESSION="<session_id>"
# List all threads
gdb-cli threads -s $SESSION
# Get backtrace (with local variables)
gdb-cli bt -s $SESSION --full
# Get registers
gdb-cli registers -s $SESSIONStep 3: Correlate Source Code (CRITICAL)
For each frame in the backtrace:
- Extract frame info:
{file}:{line} in {function} - Read source context: Get ±20 lines around the crash point
- Get local variables:
gdb-cli locals-cmd -s $SESSION --frame <N> - Analyze: Correlate code logic with variable values
Example correlation:
Frame #0: process_data() at src/worker.c:87
Source code shows:
85: Node* node = get_node(id);
86: if (node == NULL) return;
87: node->data = value; <- Crash here
Variables show:
node = 0x0 (NULL)
Analysis: The NULL check on line 86 didn't catch the issue.Step 4: Deep Investigation
# Examine variables
gdb-cli eval-cmd -s $SESSION "variable_name"
gdb-cli eval-cmd -s $SESSION "ptr->field"
gdb-cli ptype -s $SESSION "struct_name"
# Memory inspection
gdb-cli memory -s $SESSION "0x7fffffffe000" --size 64
# Disassembly
gdb-cli disasm -s $SESSION --count 20
# Check all threads (for deadlock analysis)
gdb-cli thread-apply -s $SESSION bt --all
# View shared libraries
gdb-cli sharedlibs -s $SESSIONStep 5: Session Management
# List active sessions
gdb-cli sessions
# Check session status
gdb-cli status -s $SESSION
# Stop session (cleanup)
gdb-cli stop -s $SESSIONCommon Debugging Patterns
Pattern: Null Pointer Dereference
Indicators:
- Crash on memory access instruction
- Pointer variable is 0x0
Investigation:
gdb-cli registers -s $SESSION # Check RIP
gdb-cli eval-cmd -s $SESSION "ptr" # Check pointer valuePattern: Deadlock
Indicators:
- Multiple threads stuck in lock functions
pthread_mutex_lockin backtrace
Investigation:
gdb-cli thread-apply -s $SESSION bt --all
# Look for circular wait patternsPattern: Memory Corruption
Indicators:
- Crash in malloc/free
- Garbage values in variables
Investigation:
gdb-cli memory -s $SESSION "&variable" --size 128
gdb-cli registers -s $SESSIONShow full SKILL.md (158 more words)Show less
Examples
Example 1: Core Dump Analysis
# Load core dump
gdb-cli load --binary ./myapp --core /tmp/core.1234
# Get crash location
gdb-cli bt -s a1b2c3 --full
# Examine crash frame
gdb-cli locals-cmd -s a1b2c3 --frame 0Example 2: Live Process Debugging
# Attach to stuck server
gdb-cli attach --pid 12345
# Check all threads
gdb-cli threads -s b2c3d4
# Get all backtraces
gdb-cli thread-apply -s b2c3d4 bt --allBest Practices
- Always read source code before drawing conclusions from variable values
- Use
--rangefor pagination on large thread counts or deep backtraces - Use
ptypeto understand complex data structures before examining values - Check all threads for multi-threaded issues
- Cross-reference types with source code definitions
Security & Safety Notes
- This skill requires GDB access to processes and core dumps
- Attaching to processes may require appropriate permissions (sudo, ptrace_scope)
- Core dumps may contain sensitive data - handle with care
- Only debug processes you have authorization to analyze
