dummy

dummy is a skill for Claude Code from aldianriski/lean-flow. It costs 10 tokens per session (65 once invoked), scanned A, original, MIT.

A test fixture skill containing intentionally stale content for checking whether a skill cache detects edits that were not reflected in its version.

In plain words
What is it for?
Use it in tests of skill-cache comparison and stale-content detection.
Why use it?
It helps verify that cache validation compares actual content rather than relying only on a version string.

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

dummy 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 6d 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

dummy

Stale cache version of this fixture skill (pre-edit content) — the version string was never bumped, so a string-only comparison would still report PASS. This is the trap the cache-differs leg exists to catch.

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.
