What it does
Security Guidance is an agent skill from OWASP/secure-agent-playbook. Security-first development guidance based on OWASP ASVS (Application Security Verification Standard). Use this skill automatically when planning or implementing any code that touches user input, authentication, data persistence, network communication, file I/O, cryptography, or access control. This skill ensures all generated code adheres to industry-standard security practices with explicit references to applied guidance.
Its SKILL.md is about 8.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
It sits in Security, covering Secure coding, Authorization and RBAC and Cryptography. The repository describes itself as: OWASP Secure Agent Playbook Project.
When your agent uses it
- Tasks that involve Secure coding
- Tasks that involve Authorization and RBAC
- Tasks that involve Cryptography
Example prompts
- “/security-guidance”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Identify relevant sections — Match the current task against the When to use: triggers in the index below. A task may match multiple…
- Read the reference file — For each matched section, read the full reference file listed at the end of its index entry to get the complete…
- Apply the guidance — Implement the requirements. Default to the most secure option when the requirements allow choice. Apply all Level 1…
- Cite applied requirements inline — In code comments or plan notes, reference each requirement you satisfy: // ASVS 6.2.4: password checked…
What it can do on your machine
Read from SKILL.md and the folder at commit 1b5fd4c. 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
Security Guidance loads about 8.1k tokens when it runs. Until then it costs about 111 tokens; SKILL.md has 3,935 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 (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,935 words (~8,059 tokens).
“Security is a first-class requirement. Before completing any plan or producing any code that touches security-sensitive operations, consult the ASVS reference index below and apply all relevant guidance.”
