Use before changing existing indexed files with Miller edit, especially symbol rewrites, text replacements, renames, or refactors.
Use when an agent needs extractor-recognized code-shape facts such as routes, htmx attributes, Alpine directives, SQL DDL/DML, or data-document structure.
Use when starting a Miller task, choosing a Miller tool, or choosing a Miller search mode.
Use when tracing Miller bridge paths in supported providers: dotnet-web URL literals and fetch/axios client requests to ASP.NET signals, client requests to Next.js route handlers or Nuxt server routes, Next.js/Nuxt route references to file routes, Vue/React references to route definitions, or backend-http client requests to Express/FastAPI/Flask/Django/Spring/Go/gin/echo/Rails/NestJS/Laravel/Phoenix/axum/actix/Symfony/Ktor route facts.
Use when orienting on an unfamiliar code area with Miller, explaining a module, finding entry points, or gathering context before a change.
Use when resuming Miller-backed work from a handoff packet or validating a packet before continuing in another harness, model, or session.

Use Miller's graph-backed impact tool before refactors or shared behavior changes. One impact call should replace manual reference greps.
search(query="<symbol or concept>")
inspect(target="<candidate>")
impact()
impact(target="<symbol-or-file>")
impact(changed_paths=["<file1>", "<file2>"])
impact(diff="<unified diff>")
With no args, impact() reads the working-tree git diff and maps changed ranges to impacted symbols plus likely
tests — run it after edits, before committing, to see what your uncommitted change affects. Use git=true
(base/staged imply git) to scope to a specific git diff instead.
inspect(target="<impacted-symbol>", depth="full")
trace(target="<impacted-symbol>")
trace(target="<source>", mode="path", to="<sink>")
impact reports likely tests, treat that list as the starting verification set. Add broader tests when the touched surface is shared infrastructure or cross-workspace behavior.Lead with:
Do not replace impact with rg unless Miller cannot resolve the target.
