bad-skill

bad-skill is a skill for Claude Code, Codex from fakoli/fakoli-plugins. It costs 0 tokens per session (471 once invoked), scanned A, original, MIT.

An intentionally incomplete example of a poorly specified skill.

In plain words
What is it for?
It is intended for demonstrating bad skill design and should not be used as a dependable workflow.
Why use it?
Its description does not define a reliable task, fixed process, or clear output, so its behavior is unpredictable.

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

bad-skill 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 5d 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.

What it actually says


name: bad-skill description: a skill that helps with things

bad-skill

This skill helps when things need to happen. It does what is needed and then finishes. Depending on the situation it might do one thing or another thing. The user can call this skill whenever they want and it should generally work out for them.

When invoked, consider the situation and do the appropriate action. If the situation is unclear, try to clarify it. If clarification fails, fall back to a reasonable default. The default depends on context but usually involves checking some files and then maybe writing some output somewhere sensible.

Output is whatever feels right for the situation. There's no fixed format because every situation is different. Use judgment.

There are no numbered steps in this skill because the skill is too flexible for a fixed workflow. The agent should just figure it out.

Changes

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.
