propagation-test

propagation-test is a skill for OpenCode from ZaxbyHub/opencode-swarm. It costs 7 tokens per session (245 once invoked), scanned A, original, MIT.

A testing procedure for changing one shared module seam and checking all of its consumers without separately patching each consumer.

In plain words
What is it for?
Use it for tests of shared logic that feeds multiple modules or consumers.
Why use it?
It verifies that shared behavior really propagates through the system instead of only passing through individually patched tests.

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

propagation-test 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 4d 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.

Trigger

  • knowledge propagation test
  • single-source update

Required Procedure

  • test propagation by touching only the shared module's seam and exercising all consumers without per-consumer seam overrides

Forbidden Shortcuts

  • patch each consumer's _internals in single-source propagation tests

Delegation Template

When delegating a task affected by this skill, include:

Reviewer Checks

  • Verify each required action above appears in the diff.

Test Engineer Checks

  • Add or update tests covering the trigger condition and the forbidden shortcut.

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.
