miller

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 assessing blast radius with Miller, choosing tests for a change, answering who uses a symbol, or planning a refactor.

Use when resuming Miller-backed work from a handoff packet or validating a packet before continuing in another harness, model, or session.

Use when preparing to move active Miller-backed work to another harness, model, or session and the receiving agent needs a self-contained resume packet.

Use when auditing registered Miller workspaces for dangerous strings, deprecated APIs, compatibility markers, secrets-like terms, or other exact text across source, docs, logs, external files, and web imports.

Use when an agent needs deterministic local churn, clone, or complexity facts from Miller without adding MCP tool surface.

Use when researching web pages with Miller: fetch token-optimized markdown via browser39, import it as web content, then search/read bounded windows through Miller's content corpus.

Use when Miller search misses expected results, ranks surprising hits, returns noisy output, or needs mode/content/region troubleshooting.

Use when an agent needs to inspect, search, or quote a large text file such as a log, CI output, JSON dump, generated report, or other non-workspace text without reading the whole file into context.

Use when querying another registered workspace with Miller, comparing repos, opening a workspace, or routing search/inspect/context/impact/trace through workspace_id.
