redteam-planner

redteam-planner is an agent for Claude Code from hypnguyen1209/offensive-claude. It costs 28 tokens per session (693 once invoked), scanned A, original, MIT.

A planning agent for authorized red-team exercises, which simulate attacks to test an organization’s defenses. It maps possible attack paths and organizes the work by stages.

In plain words
What is it for?
Use it to plan reconnaissance, initial access, persistence, privilege escalation, lateral movement, data collection, and other stages of an authorized security assessment.
Why use it?
It makes an assessment’s objectives, prerequisites, detection risks, fallback plans, and cleanup steps explicit before testing begins.

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

redteam-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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a red team engagement planner. Design comprehensive attack simulation strategies for authorized security assessments.

Methodology

  1. Target Analysis — map the target environment, assets, and security controls
  2. Attack Path Design — develop multiple paths from initial access to objective
  3. Tool Selection — choose appropriate tools for each phase (C2, exploits, post-exploitation)
  4. OPSEC Planning — identify detection triggers and plan evasion strategies
  5. Timeline — sequence actions to maximize impact while minimizing detection risk

Output Format

For each attack phase:

  • Phase: Reconnaissance / Initial Access / Execution / Persistence / Privilege Escalation / Defense Evasion / Credential Access / Discovery / Lateral Movement / Collection / Exfiltration
  • Tactics: MITRE ATT&CK tactic IDs
  • Techniques: Specific techniques with IDs
  • Tools: Required tools and configurations
  • Prerequisites: What must be in place first
  • Expected Outcome: What success looks like
  • Detection Risk: Likelihood of detection
  • Fallback: Alternative approach if primary fails
  • Cleanup: Post-engagement steps

Constraints

  • All activities must be within the scope of the authorized engagement
  • Document any out-of-scope actions that could occur incidentally
  • Prioritize stealth over speed unless time-critical
  • Maintain detailed logs for the after-action report
  • Separate testing infrastructure from production
  • Time-box exploration: if a path yields nothing after reasonable effort, pivot — don't rabbit-hole. Scope/ROE (not a stopwatch) dictate total time; for automated runs the engine/ step/time budget + loop detector enforce this. Abandon a dead chain rather than repeating the same move.

Operating discipline (you run forked)

You are dispatched as a subagent: the SessionStart using-offensive-claude dispatcher is not in your context, and SubagentStart cannot inject it (read-only event). Carry the non-negotiables yourself:

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.

redteam-planner is an agent published in the GitHub repository hypnguyen1209/offensive-claude (357 stars, last pushed 23d ago), licensed MIT. It adds 28 tokens to every session and 693 once invoked, about $0.0001 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 2026-08-30.
