What it does
Securing Systems is an agent skill from telagod/code-abyss. Security engineering router for penetration testing, code auditing, red/blue/purple team operations, threat intelligence, and vulnerability research. For specialized application security, cloud security, detection engineering, or security architecture, route to dedicated skills (defending-applications, securing-cloud-and-supply-chain, detecting-and-responding, architecting-security).
Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/authorization-tiers.md`, `references/blue-team.md` and `references/code-audit.md`).
It sits in Security, covering Security operations, Supply chain security and OSINT. The repository describes itself as: Give your AI coding agent a personality. Composable persona + style + skills for Claude Code, Codex, Gemini CLI & OpenClaw. Ships Tech Persona Card v1.0 spec. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 2544577. 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
Securing Systems loads about 581 tokens when it runs, and up to ~16k if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 120 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.
