Get Perspective On is an agent skill from Abilityai/cornelius. Extract the user's perspective on a topic (called by a content agent or user)
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: AI-powered second brain template for Claude Code + Obsidian. The licence is MIT.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit fd5e9a4. 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.
Shell commands in SKILL.md call:
claudeFrom 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.
Get Perspective On loads about 864 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 292 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); files beside SKILL.md are not scanned.

}Good perspective: ✅ Cites 3-5 specific permanent notes ✅ Highlights contrarian or non-obvious angles ✅ Connects to broader themes ✅ Includes concrete examples ✅ Authentic your voice
Weak perspective (regenerate): ❌ Generic AI knowledge ❌ No specific note citations ❌ Surface-level analysis ❌ Lacks unique angles

Run `npx skills add Abilityai/cornelius --skill get-perspective-on -a claude-code`. Or copy the skill folder (.claude/skills/get-perspective-on in Abilityai/cornelius) into .claude/skills/get-perspective-on in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Abilityai/cornelius --skill get-perspective-on -a codex`. Or copy the skill folder (.claude/skills/get-perspective-on in Abilityai/cornelius) into .agents/skills/get-perspective-on 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 Abilityai/cornelius --skill get-perspective-on -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/get-perspective-on, .gemini/skills/get-perspective-on, .github/skills/get-perspective-on and .opencode/skills/get-perspective-on in your project.
Going by SKILL.md and its folder, Get Perspective On needs the command-line tools its instructions call (claude).
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. Review the folder before installing.
Get Perspective On is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 864 tokens (SKILL.md is roughly 3.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Get Perspective On: Extract (alirezarezvani/claude-skills, 28k stars), Brand Extract (nexu-io/open-design, 100k stars), Design Extract (nexu-io/open-design, 100k stars) and Kg Extract (ruvnet/ruflo, 74k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
