principle-explain-the-numberApply before you trust, report, or act on a number you measured: a speedup, a regression, a throughput, a latency, or an eval result.
Principle Explain The Number is an agent skill from cursor/plugins, published by the product's own GitHub organization. Apply before you trust, report, or act on a number you measured: a speedup, a regression, a throughput, a latency, or an eval result. Find what limits it, and rule out that it measured something other than the work you think.
Its SKILL.md is about 530 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: Cursor plugin specification and official plugins.
Read from SKILL.md and the folder at commit ccb5507. 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.
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.
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.
Principle Explain The Number loads about 528 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 315 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.
Without a licence we can't republish the file, so here is its outline and opening line. It has 315 words (~528 tokens).
“A measured number is a claim about a system. Before you trust it, report it, or act on it, find what limits it and rule out that it measured something else.”
Just SKILL.md in pstack/skills/principle-explain-the-number of cursor/plugins.

cursor/plugins
Keeps a TSV decision log for long or unattended agent runs, one row per decision with what, why, evidence and result, so a reviewer can check the work later.
cursor/plugins
Digs into why code is shaped the way it is by checking git history, pull requests and connected tools in parallel, then reporting a cited read on the tradeoffs.
cursor/plugins
Starts three parallel reviewer subagents over the current conversation transcript, then turns their findings into concrete edits to existing skills.
cursor/plugins
Applies four layers of technical-writing rules to docs, RFCs, readmes, PR descriptions and commit messages so a tired engineer follows them on the first read.
cursor/plugins
Adds a second, stronger model that the main agent consults before major decisions, when stuck and before finishing, controlled by /advisor commands.
cursor/plugins
Prepare PRs for review by cleaning noisy history, improving PR descriptions, and adding reviewer guidance without changing code behavior.

Run `npx skills add cursor/plugins --skill principle-explain-the-number -a claude-code`. Or copy the skill folder (pstack/skills/principle-explain-the-number in cursor/plugins) into .claude/skills/principle-explain-the-number in your project. Claude Code loads it when a task matches its description.
Run `npx skills add cursor/plugins --skill principle-explain-the-number -a codex`. Or copy the skill folder (pstack/skills/principle-explain-the-number in cursor/plugins) into .agents/skills/principle-explain-the-number 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 cursor/plugins --skill principle-explain-the-number -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/principle-explain-the-number, .gemini/skills/principle-explain-the-number, .github/skills/principle-explain-the-number and .opencode/skills/principle-explain-the-number in your project.
SKILL.md names no scripts, command-line tools or credentials: Principle Explain The Number is instructions for the agent only.
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.
No licence was found for Principle Explain The Number or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 528 tokens (SKILL.md is roughly 2.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
