secleak-checkRun or install repo security leak checks with BetterLeaks and Trivy.
Secleak Check is an agent skill from instructa/agent-skills. Run or install repo security leak checks with BetterLeaks and Trivy. Use when asked to scan for leaked secrets, vulnerable dependencies, misconfigurations, add secret-leak guardrails, add BetterLeaks, add forbidden-path hooks, or run secleak-check before release.
Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `README.md`, `references/examples.md` and `references/guardrails.md`).
It sits in AI & LLM Engineering, covering Secrets management, Vulnerability scanning and LLM guardrails. It works with Trivy. The repository describes itself as: A curated collection of agent-skills.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit d49c149. It shows what the files ask for, not the result of running them.
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.
Ships 2 files in scripts/ (JavaScript and Shell), which the agent can run.
Shell commands in SKILL.md call:
trivyFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Secleak Check loads about 557 tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 69 tokens; SKILL.md has 226 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.
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); the scripts in this folder are not scanned.
Without a licence we can't republish the file, so here is its outline and opening line. It has 226 words (~557 tokens).
“Resolve scripts/secleak-check.sh relative to this SKILL.md.”

Run or install repo security leak checks with BetterLeaks and Trivy. Secleak Check is an agent skill from instructa/agent-skills. Run or install repo security leak checks with BetterLeaks and Trivy.
Secleak Check fits situations like: asked to scan for leaked secrets; vulnerable dependencies; misconfigurations; add secret-leak guardrails.
Run `npx skills add instructa/agent-skills --skill secleak-check -a claude-code`. Or copy the skill folder (skills/security/secleak-check in instructa/agent-skills) into .claude/skills/secleak-check in your project. Claude Code loads it when a task matches its description.
Run `npx skills add instructa/agent-skills --skill secleak-check -a codex`. Or copy the skill folder (skills/security/secleak-check in instructa/agent-skills) into .agents/skills/secleak-check in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add instructa/agent-skills --skill secleak-check -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/secleak-check, .gemini/skills/secleak-check, .github/skills/secleak-check and .opencode/skills/secleak-check in your project.
Going by SKILL.md and its folder, Secleak Check needs JavaScript and a shell for the scripts in its folder and the command-line tools its instructions call (trivy). Our summary lists: Node.js; A Bash shell.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
No licence was found for Secleak Check or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 557 tokens (SKILL.md is roughly 2.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.3k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Secleak Check: Performing Container Security Scanning With Trivy (mukul975/Anthropic-Cybersecurity-Skills, 34k stars), Dep Updates (trufflesecurity/trufflehog, 28k stars), Security Reviewer (Jeffallan/claude-skills, 12k stars) and Wa Guardrails (aws-samples/sample-well-architected-skills-and-steering, 273 stars).
