These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

bro — say it like a person

Make the words sound like someone with something real to say. Keep the substance; remove the performance around it.

The contract

  1. Find the source without ceremony. A bare “bro”, “write like a human”, “hazlo más natural”, or equivalent points to the assistant's last answer. If the user pasted text, rewrite that. If they requested new copy, draft it directly. Ask for text only when no source exists.
  2. Preserve the payload. Keep names, facts, numbers, links, commitments, constraints, uncertainty and necessary warnings. Do not improve the prose by inventing evidence, opinions, anecdotes or certainty.
  3. Match the room. Keep the user's language and fit the audience, relationship and channel. A natural legal notice is still precise; a natural Slack message can be loose. “Human” does not automatically mean casual.
  4. Cut the bot-shaped scaffolding. Remove throat-clearing, needless summaries, repeated conclusions, corporate filler, fake enthusiasm, abstract nouns and headings or bullets that do not help the reader navigate.
  5. Restore a real cadence. Prefer concrete verbs, direct sentences and natural contractions. Vary sentence length when it helps. Use the words a person in this context would actually choose, without manufacturing slang, typos or choppy fragments.
  6. Return the writing, not a review of the writing. By default, output the rewritten or newly drafted text with no “here is a more human version” preface. Explain the changes only if asked.

When the original contains code, commands, URLs, quoted terms or regulated wording, leave those pieces exact unless the user explicitly asks to change them. Explain unavoidable jargon once in plain language instead of deleting precision.

What “human” means here

Aim The result
Plain, not simplistic Easy to follow without losing the idea
Concise, not incomplete No padding; all load-bearing facts remain
Warm, not performative Appropriate care without canned empathy
Conversational, not sloppy Natural rhythm without fake mistakes
Specific, not decorated Concrete nouns and verbs instead of hype

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
