sample-plugin

A small sample plugin used to test compatibility with installations that provide a skill file but no separate plugin metadata file.

In plain words
What is it for?
Use it in end-to-end tests involving skill-file front matter, plugin metadata, user-brief handling, task planning, and deck artifacts.
Why use it?
It gives plugin developers a repeatable fixture for checking that older or minimal installations are interpreted correctly.

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

sample-plugin 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 yesterday.

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.

Origin

This is a copy

94% identical to sample-plugin — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Sample Plugin

This is the SKILL.md half of the Phase 1 e2e fixture. The companion open-design.json sidecar carries the canonical Open Design plugin manifest fields; this file proves the SKILL-only adapter path stays honest when an install lacks an explicit sidecar (just delete open-design.json to test the legacy compat tier).

Workflow

  1. Acknowledge the user's brief via the discovery question form atom.
  2. Use TodoWrite to plan the brief.
  3. Emit the brief as a deck artifact.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
