Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Echo Skill
The simplest possible skill — it echoes the user's wish back as the result.
When to use
Use this skill when the user wish is:
- A greeting: "hi", "hello", "hey there"
- A literal echo request: "echo hello world", "say something"
- A smoke test: "is this working?"
- Anything purely conversational that doesn't need data, fetching, or analysis
How to respond
No tools needed. No scripts to call. Just respond with a single message that includes the user's wish text wrapped in a brief acknowledgment.
Format:
You said: That's the entire skill. Done.
What this skill demonstrates
This SKILL.md format is the standard Claude Code skill format. The TAR Engine reads this file and puts it in the LLM's system prompt. The LLM then produces a response — for trivial skills like this one, no run_bash / read_file / write_file tool calls are needed.
For skills that need data or scripts, the SKILL.md instructs the LLM to call run_bash to invoke scripts in the same skill directory. See url-summarize/SKILL.md in this pack for that pattern.
