What it does

Memstack Security Owasp Top10 is an agent skill from cwinvestments/memstack. Use this skill when the user says 'OWASP audit', 'OWASP top 10', 'security audit', 'vulnerability assessment', 'full security check', or needs a comprehensive web application security review against OWASP Top 10 categories. Do NOT use for dependency audits or secret scanning alone.

Its SKILL.md is about 5k 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 Security, covering Web application vulnerabilities and Security review. The repository describes itself as: Structured skill framework for Claude Code. 130 skills, persistent memory, TokenStack compression, localhost dashboard with 3-agent runner, real-time streaming, MCP tools.

When your agent uses it

  • The user says OWASP audit
  • Vulnerability assessment
  • Full security check
  • Needs a comprehensive web application security review against OWASP Top 10 categories

Example prompts

  • “OWASP audit”
  • “OWASP top 10”
  • “security audit”
  • “/memstack-security-owasp-top10”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Missing auth on routes
  2. Insecure Direct Object References (IDOR)
  3. Privilege escalation
  4. CORS bypass

What it can do on your machine

Read from SKILL.md and the folder at commit 00370ce. 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:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    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

Memstack Security Owasp Top10 loads about 5k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 2,157 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~5k

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.

SKILL.md

Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,157 words (~5,014 tokens).

“Audit a web application against the OWASP Top 10 (2021) vulnerability categories with actionable findings and remediation.”
