At a glance
Give a capable engineer a terse, jargon-free briefing on the critical facts and implications of an effort before it is built or after it is completed.

What it does
Facts is an agent skill from backnotprop/bro. Give a capable engineer a terse, jargon-free briefing on the critical facts and implications of an effort before it is built or after it is completed. Use when the human explicitly invokes $facts, and never otherwise; do not invoke this skill automatically.
Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
When your agent uses it
- The human explicitly invokes $facts
- Never otherwise
- Do not invoke this skill automatically
Example prompts
- “/facts”
What it can do on your machine
Read from SKILL.md and the folder at commit 523ed36. 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
Facts loads about 304 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 149 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 149 words (~304 tokens).
“What are the most important facts I should know about we plan to build in this subject scope/next phase (or after if we've completed the subject scope). Instead of an exhaustive list, list only the most critical things with implications…”

When should I use Facts?
Facts fits situations like: the human explicitly invokes $facts; never otherwise; do not invoke this skill automatically.
How do I install Facts in Claude Code?
Run `npx skills add backnotprop/bro --skill facts -a claude-code`. Or copy the skill folder (skills/facts in backnotprop/bro) into .claude/skills/facts in your project. Claude Code loads it when a task matches its description.
How do I install Facts in Codex?
Run `npx skills add backnotprop/bro --skill facts -a codex`. Or copy the skill folder (skills/facts in backnotprop/bro) into .agents/skills/facts in your project. Codex loads it when a task matches its description.
Can I use Facts in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add backnotprop/bro --skill facts -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/facts, .gemini/skills/facts, .github/skills/facts and .opencode/skills/facts in your project.
What does Facts need to run?
SKILL.md names no scripts, command-line tools or credentials: Facts is instructions for the agent only.
Does Facts access the network?
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.
Is Facts safe to install?
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.
What licence does Facts use?
No licence was found for Facts or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Facts use?
About 304 tokens (SKILL.md is roughly 1.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Facts?
Skills that share tags, products or a category with Facts: Brief (alirezarezvani/claude-skills, 28k stars), Agentic Engineering (affaan-m/ECC, 275k stars), Product Capability (affaan-m/ECC, 275k stars) and Prompt Engineering (davila7/claude-code-templates, 32k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
