What it does
Memstack Security API Audit is an agent skill from cwinvestments/memstack. Use this skill when the user says 'audit API', 'check API security', 'API routes security', 'endpoint audit', 'check my routes', or needs to verify API route protection. Reviews API endpoints for authentication, authorization, and input validation gaps. Do NOT use for frontend security headers or dependency scanning.
Its SKILL.md is about 3.9k 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 Backend & APIs, covering Authentication, REST APIs and Secure coding. It works with Next.js. 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 audit API
- Check API security
- API routes security
- Check my routes
Example prompts
- “audit API”
- “check API security”
- “API routes security”
- “/memstack-security-api-audit”

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:
stripe
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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 API Audit loads about 3.9k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 1,398 words of instructions outside code blocks.
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 1,398 words (~3,882 tokens).
“Audit Next.js API routes for authentication, authorization, validation, and common vulnerabilities.”
