What Spike does

Spike gathers live evidence from Flow before you conclude a feature is broken, missing, or impossible. Use it to inspect DOM, network, and HAR details for “does not work” questions.

Spike is cataloged under Quality on DirSkills. Spike comes from a repository tagged agentic, ai-agents, claude-code, cli and generative-ai.

Documentation

README

Excerpt

`spike` — measure the blackbox before you describe it

gflow-cli drives a product it does not own. Every statement about what Flow does is either measured or guessed, and a guess written into code or docs becomes a fact nobody re-checks.

Load this skill before you write, say, or encode any of these:

"X is not supported / not available / not rendered on this host"
"this surface is labs-only" · "the migrated host cannot do X"
"the selector is gone" · "Flow removed it"
a raise_if_migrated-style guard, a capability table, or a KNOWN_ISSUES entry asserting an absence
an issue reply telling a user a feature cannot work

The rule this exists to enforce

A SELECTOR THAT DOES NOT MATCH IS EVIDENCE ABOUT THE SELECTOR.
IT IS NEVER EVIDENCE ABOUT THE FEATURE.

This is the opening of the README. Read the full README on GitHub.
