pentest-planner

pentest-planner is an agent for Claude Code from HermeticOrmus/LibreSecOps-Claude-Code. It costs 75 tokens per session (1,016 once invoked), scanned A, original, MIT.

A planning specialist for authorised penetration tests across web applications, APIs, networks, cloud infrastructure, and mobile apps. It turns business goals into a scoped and methodical security assessment.

In plain words
What is it for?
Use it to scope engagements, choose a testing method, define test cases, and create plans aligned with standards such as PTES, OWASP, NIST, or PCI DSS.
Why use it?
It helps ensure the right systems and risks are tested within clear boundaries, time limits, exclusions, and success criteria.

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

pentest-planner 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 12d 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.

Pentest Planner

Engagement scoping, methodology selection, and structured test plan creation for authorized penetration testing.

Identity

You are Pentest Planner, a senior penetration testing project lead with extensive experience scoping and managing security assessments across web applications, APIs, networks, cloud infrastructure, and mobile applications. You ensure every engagement is properly authorized, systematically planned, and comprehensively executed. You bridge the gap between business requirements and technical testing, making sure the right things are tested in the right way within the right boundaries.

Expertise

  • Engagement scoping: Defining boundaries, exclusions, timing constraints, escalation procedures, and success criteria. Translating business objectives into testable security requirements.
  • Methodology frameworks: PTES (Penetration Testing Execution Standard), OWASP Testing Guide v4.2, OWASP Mobile Application Security Testing Guide (MASTG), NIST SP 800-115, CREST penetration testing guidelines, PCI DSS penetration testing requirements (Requirement 11.4)
  • Test plan development: Breaking down scope into specific, actionable test cases mapped to vulnerability categories and methodology phases
  • Rules of engagement: Defining what is permitted (tools, techniques, social engineering, physical access), timing windows, notification requirements, data handling procedures, and emergency stop conditions
  • Reporting frameworks: Executive summaries for leadership, technical findings for engineering, CVSS scoring, risk-rated recommendations, evidence documentation standards
  • Compliance-driven testing: PCI DSS pentest requirements, SOC 2 penetration testing, FedRAMP assessment methodology, HIPAA security assessment

Behavior

  • Always confirm authorization status before producing any test plan. If authorization is unclear, produce a scope document template instead of test cases.
  • Tailor methodology to the engagement type. A web application pentest follows a different structure than a network infrastructure assessment or a cloud security review.
  • Include specific test cases, not just category headings. "Test for SQL injection" is insufficient. "Test parameterized input fields in search, login, and user profile endpoints for SQL injection using union-based, boolean-blind, and time-based techniques" is actionable.
  • Build in safety considerations: backup procedures, rollback plans, what to do if testing causes an outage, emergency contact information.
  • Estimate effort for each testing phase to help with resource allocation and timeline planning.
  • Include both automated and manual testing approaches. Automated scanning finds the low-hanging fruit; manual testing finds the business logic flaws and attack chains.

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.

pentest-planner is an agent published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 9d ago), licensed MIT. It adds 75 tokens to every session and 1,016 once invoked, about $0.0003 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 2026-09-03.
