managed-pentesting-with-strix

managed-pentesting-with-strix is a skill for Claude Code, Codex from usestrix/strix. It costs 114 tokens per session (5,402 once invoked), scanned B, original, Apache-2.0.

A managed web-application and API penetration-testing workflow that sends scans to Strix Cloud, an online security-testing service. It uses the service through its API, so local Docker and local language-model setup are not required.

In plain words
What is it for?
Use it to register assets, launch and monitor scans, review vulnerabilities, export SARIF results, and download pentest reports.
Why use it?
It lets hosted agents, teams, and CI systems run security tests without maintaining the scanning infrastructure themselves.

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 B, and why

managed-pentesting-with-strix scanned grade B with 2 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 yesterday.

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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 322 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Strix Cloud (managed, no local infra)

Use this when you want Strix's autonomous pentesting without running Docker or an LLM yourself — the scan runs on Strix's infrastructure and results are tracked in a team dashboard. This is the right choice in sandboxed/hosted agent and CI environments, for teams, and for scheduled/continuous testing (downloadable PDF/DOCX reports are an Enterprise-plan feature). For fully local, free, air-gapped, or BYO-LLM runs, use the open-source CLI in the penetration-testing-with-strix skill instead — both share the same engine and SARIF output, so you can mix them.

There are two equivalent interfaces. Prefer the CLI:

  • strix cloud CLI — every REST operation has a command in the form strix cloud <resource> <verb>. Install with curl -sSL https://strix.ai/install | bash. Run strix cloud to list all resources and strix cloud <resource> help (or -h) to list a resource's verbs; a bare resource with a safe read operation runs its documented default.
  • REST API — base URL https://app.strix.ai/api/v1, Authorization: Bearer <token> on every request. Full reference: docs.app.strix.ai · agent index: https://docs.app.strix.ai/llms.txt · OpenAPI: https://docs.app.strix.ai/openapi.json.

The CLI is equally usable by agents and people. Output is complete JSON when stdout is not a terminal, or when you pass --json; terminal tables favor names, branches, lifecycle states, and numbered selectors. Human lists retain the selectors needed by follow-up commands but omit internal organization/user IDs; a selector too long for the compact table is repeated losslessly in a copyable block. Paginated lists print the next --page or --offset, and detail views preserve useful prose within a safe terminal bound; use --json for the complete record. Token lists label credentials as active, expired, or revoked. Binary downloads are the exception: redirect raw bytes intentionally, or use --output FILE --json to write the file and receive structured metadata. There are no interactive prompts when stdin is not a terminal. Exit codes: 0 success, 1 request/runtime error, 2 invalid usage, 4 authentication or plan limit, 5 payment required.

Every resource group with a safe read operation has a useful default action, and -h or help always shows its verbs. Native tab completion includes resources, verbs, flags, workspace commands, and local paths:

source <(strix completions zsh)       # current zsh session
source <(strix completions bash)      # current bash session
strix completions fish | source       # current fish session

Write commands take request fields as flags. Every write command also accepts one JSON object with --data, which is the way to send fields that have no flag:

strix cloud scans start --data '{"engagement_type":"code_review"}'   # literal JSON
strix cloud scans start --data @request.json                         # read a file
cat request.json | strix cloud scans start --data -                  # read standard input

The platform enforces plan and role limits, and the CLI passes the platform message through. Report downloads need the Enterprise plan. Schedules need the Pro plan. Billing writes need an admin token. A blocked command exits with code 4.

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.

It adds 114 tokens to every session and 5,402 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
