How to use the Exploit Development Guide agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The Exploit Development Guide agent skill, folder name offensive-exploit-development, is a methodology document that tells an AI agent to follow a structured checklist while you build exploits for software vulnerabilities. It is written for security researchers, students and penetration testers working on authorised engagements. After reading this guide you will be able to install the skill, trigger it with natural requests and know what it needs and what its limits are.
Exploit Development GuideSnailSploit/Claude-Red · MIT Download the skill Quick start
- 1Download the ZIP. Download the offensive-exploit-development skill ZIP from this page.
- 2Unzip the folder. Unzip the archive so the offensive-exploit-development folder containing SKILL.md is present.
- 3Choose a location. Place the folder in ~/.claude/skills/ for personal use, or in .claude/skills/ inside a specific project.
- 4Or upload in the apps. In the Claude apps, go to Settings → Capabilities → Skills and upload the skill instead.
- 5Install optional tools. If you want tooling the agent may recommend, install pwntools, pwndbg, keystone engine, or lief yourself, since none are bundled.
- 6Trigger with a natural request. Ask about a trigger topic such as pwntools, heap exploitation or exploit reliability, stating your authorised target.
- 7Follow the checklist. Work through the lifecycle stages the agent gives you and ask it to track completed items.
What the skill makes the agent do
The skill loads a full exploit development methodology into the agent and asks it to use that as an operational checklist. The source describes the process as bug identification, vulnerability analysis (root cause, trigger and impact), weaponization (mitigation bypass, payload development and reliability improvements), then testing and deployment. The agent is told to follow the steps in order unless you say otherwise, track which items are done and suggest next steps based on findings.
The content covers bug types such as stack overflow, use after free and heap overflow, with case-study outlines, Windows SEH internals, egghunting, heap allocator background and tooling such as pwntools and pwndbg. The skill changes how the agent organises and explains this work. It does not add new software actions and it does not run code.
- Organises exploit work into a lifecycle checklist
- Explains bug classes, mitigations and Windows exception-handling concepts
- Suggests tooling such as pwntools, pwndbg, keystone engine, lief or dumpbin, which you must install yourself
Install the skill from a ZIP file
Download the ZIP of the skill from this page and unzip it. The skill is a folder containing SKILL.md. Place the folder in one of two locations depending on how you want to use it: your personal skills folder at ~/.claude/skills/, or a project-specific .claude/skills/ folder inside the project you are working in.
If you use the Claude apps instead, you can upload the skill under Settings → Capabilities → Skills rather than copying files by hand.
- Personal use: unzip into ~/.claude/skills/
- Single project: unzip into .claude/skills/ in that project
- Claude apps: upload under Settings → Capabilities → Skills
~/.claude/skills/offensive-exploit-development/SKILL.mdTrigger the skill with natural requests
The skill activates when the conversation involves its trigger phrases. You do not need to name the skill. Mention the topic directly in your request. The trigger list is narrow, so use the terms it names. Phrases in the source include exploit development, pwntools, pwndbg, heap exploitation, PoC development, exploit reliability, weaponization, debugging workflow and exploit dev environment.
Good requests state the task and the context, for example the stage of work you are at and the target you are authorised to test.
- Set up an exploit dev environment with pwntools and pwndbg for this authorised lab binary
- Walk me through the next steps of the exploit development process for this stack overflow finding
- Help me improve exploit reliability for my PoC on the test VM
- Explain how SEHOP and SafeSEH affect a SEH overflow on this module
What to expect in the output
The agent will treat the methodology as a checklist, so answers often reference the stage you are at, such as root cause analysis, mitigation bypass or reliability testing. It will consider whether each technique applies to your target. The source also notes that the methodology links to other documents such as bug identification, fuzzing, mitigations and heap samples. Those linked files are not included in the SKILL.md file, so the agent works from what is inside that one file.
- Expect checklist-style answers organised by lifecycle stage
- Expect per-target checks, for example whether a module uses Guard EH Continuations
- Expect references to linked topics that you may need to supply yourself
Requirements, safety and limits
The skill needs no installed runtime from this page. The optional tools pwntools, pwndbg, keystone engine, and lief or dumpbin are not bundled and must be installed separately if you want them. The skill does not run scripts and does not use the network.
Use it only against systems you own or have explicit permission to test. Building working exploits against systems you are not authorised to test can be illegal and harmful. The file contains no executable exploit framework, so it is not a turnkey tool for beginners.
- Runs scripts: no
- Uses network: no
- Optional and not bundled: pwntools, pwndbg, keystone engine, lief, dumpbin
- Licence: MIT
Tips for getting useful results
Give the agent concrete facts about your target, such as the bug class, the mitigations present and the tooling you have. Ask it to track which checklist items are complete so you can see progress across a long session. Verify any mitigation claim against your own target, because the source stresses that adoption of protections varies by binary and build.
- State the bug class and the mitigations in place up front
- Ask the agent to track completed checklist items
- Verify mitigation status per binary rather than assuming it
- Keep the skill for specialised security work; narrow triggers mean unrelated tasks may not activate it
What people use it for
- Structuring an authorised exploit development engagement into bug identification, analysis and reliability stages
- Studying how a stack overflow case study moves from bug to payload and how mitigations affect it
- Learning Windows SEH concepts such as handler chains, pop-pop-ret sequences and bad characters
- Planning an egghunter approach when a payload has no room at a static address
- Setting up an exploit dev environment checklist with pwntools and pwndbg in a lab
Frequently asked questions
How do I install the Exploit Development Guide agent skill?
Download the ZIP from this page and unzip it so the offensive-exploit-development folder with SKILL.md is in ~/.claude/skills/ for personal use or .claude/skills/ inside a project. You can also upload it in the Claude apps under Settings → Capabilities → Skills.
Is the offensive-exploit-development skill free to use?
The skill is published under the MIT licence, as stated on this page. Check the licence text included with the source for the full terms before you reuse it.
What do I need to run this skill?
You need an agent environment that supports skills. The skill itself runs no scripts and uses no network. Tools such as pwntools, pwndbg, keystone engine, and lief or dumpbin are optional and not bundled, so install them separately if you want them.
Is this skill an exploit framework I can run?
No. The file is a methodology checklist that guides the agent's explanations and organisation. It contains no executable scripts and is not a runnable exploit framework.
Why isn't the skill triggering when I ask about exploits?
Triggers are narrow and match specific phrases such as exploit development, pwntools, pwndbg, heap exploitation, PoC development and exploit reliability. Use one of those terms in your request, and check that the folder is in the correct skills location.
What are the alternatives to this skill?
The source does not compare this skill with other tools, so this guide cannot make a verified comparison. If you need a runnable tool rather than a checklist, look for a dedicated exploit framework, but only use any tool on systems you are authorised to test.

Our verdict
Use this skill if you are a security researcher, student or authorised penetration tester who wants an agent to follow a structured exploit development checklist and explain the concepts. Pick something else if you need a turnkey tool, want to run exploits without a clear authorisation, or need help with non-security tasks.
