prism-scan

Structural analysis through dynamically generated cognitive lenses. Generates the optimal analytical lens for the specific code/artifact, then executes it. Finds conservation laws, structural invariants, and concrete bugs that vanilla analysis misses. Use on any code file, system design, or text artifact.

# Prism Scan — Structural Analysis via Dynamic Cognitive Lenses

## When to Use

Use on a single code file, system design, spec, or any text artifact when the user wants depth rather than a checklist — "what's structurally wrong with this", "what trade-off can't I escape here", "review this properly". Also the right entry point when the user names a focus ("focusing on security", "with emphasis on performance"). For maximum depth on an important artifact use `/prism-full`; to map which angles are worth taking first use `/prism-discover`.

You perform TWO steps. Both are mandatory. Do not skip either.

## STEP 0: Check for prior constraint knowledge (growth)

Look for a `.prism-history.md` file in the current project directory. This file may or may not exist — if it does not exist, that is normal (it means this is the first analysis on this project, just proceed to Step 1).

If the file DOES exist, read it. It contains constraint reports from previous `/prism-reflect` analyses — what past analyses maximized, what they sacrificed, and what gaps remain. Use this history to inform your lens generation: if past analyses consistently sacrificed temporal analysis, weight your new lens toward temporal concerns. The agent grows by not repeating the same blind spots.
