What it does
Spring Boot Security is an agent skill from HoangNguyen0403/agent-skills-standard. Configure Spring Security 6+ with Lambda DSL, JWT, and hardening rules. Use when configuring Spring Security 6+, OAuth2, JWT, or security hardening in Spring Boot.
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).
It sits in Backend & APIs, covering Backend development and Authentication. It works with Spring Boot. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.
When your agent uses it
- Configuring Spring Security 6+
- Security hardening in Spring Boot
Example prompts
- “/spring-boot-security”
What it can do on your machine
Read from SKILL.md and the folder at commit b529c2d. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Spring Boot Security loads about 526 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 46 tokens; SKILL.md has 171 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.

- description
- Configure Spring Security 6+ with Lambda DSL, JWT, and hardening rules. Use when configuring Spring Security 6+, OAuth2, JWT, or security hardening in Spring Boot.
Spring Boot Security Standards
Priority: P0 (CRITICAL)
Configure SecurityFilterChain
- Lambda DSL: ALWAYS use Lambda DSL.
- SecurityFilterChain: Expose as
@Bean. not extendWebSecurityConfigurerAdapter. - Statelessness: Enforce
SessionCreationPolicy.STATELESSfor REST APIs.
See implementation examples for SecurityFilterChain configuration with Lambda DSL and JWT.
Implement Authentication and Authorization
- Authentication: Validation of credentials (Who you?). Use
AuthenticationManagerorJwtDecoder. - Authorization: Verification of access rights (Can you this?). Use
@PreAuthorize.
Secure JWT Tokens
- Algorithm: Enforce
RS256orHS256. Rejectnonealgorithm. - Claims: Validate
iss,aud, andexp. - Tokens: Short-lived access JWTs (15m), secure refresh tokens (httpOnly cookie).
Hardening Checklist
- CSRF: Disabled for pure APIs? Enabled + Cookie for Browser Apps?
- CORS: Specific origins permitted? No
*with credentials? - Headers: HSTS, Content-Type-Options, X-Frame-Options enabled?
- Secrets: No hardcoded keys? Loaded from Vault/Env?
- Rate Limiting: Applied on login/expensive endpoints?
- Dependencies: Scanned for CVEs?
Anti-Patterns
- No Adapter: Use
SecurityFilterChainbean instead of extending legacy classes. - No .and(): Use Lambda DSL for configuration.
- No Secrets: Load from Vault or Environment variables (never git).
- No antMatchers: Use
requestMatchers(Spring Security 6+).
