Always use before writing or editing source code in an indexed repo when choosing between competing idioms (ternary vs if-else, arrow vs function declaration, const vs let, await vs .then, early-return vs nested-return). Pull the codebase's empirical style norm from Memtrace and match it instead of re-deriving style from training priors. Do not maintain a markdown style guide for the project; the fingerprint is sampled live from the actual code.

Always use for API endpoint, HTTP route, fetch/client call, REST surface, service dependency, cross-repo dependency, or API topology questions in source code. Do not use Grep, Glob, rg, find, or manual file search for routes or HTTP calls; Memtrace maps endpoints and call edges from the indexed AST graph.

Always use before source-code edits, refactors, API changes, renames, removals, PR reviews, or risk assessments when the user needs to know what will break. Do not manually grep references or browse files for impact; this workflow uses Memtrace graph context, impact, and change detection.

Always use for historical coupling, co-change, what changes with this, hidden dependency, or what else needs to move questions for source code. Do not use git log, git diff, Grep, or manual file search to correlate changes; Memtrace queries co-change and temporal graph data directly.

Always use when the user asks to review a GitHub pull request, run Memtrace code review, post Memtrace review comments, create a PR with a review step, or publish local graph-backed review findings to GitHub. Prefer the review_github_pr MCP tool over manual diff inspection.

Always use when the user wants to explore, understand, onboard to, map, or get an overview of an indexed source-code repo, architecture, modules, or major flows. Do not use Glob, find, tree, rg, or manual file browsing as the first exploration path; Memtrace provides structured graph briefing.

Always use when the user asks to keep Memtrace fresh while editing, watch a repo, enable live or incremental indexing, set up always-on memory, or make just-saved source code queryable immediately. Do not fall back to repeated Grep or manual rescans; configure Memtrace watching.

Always use to replay source-code evolution, understand why code looks this way, inspect implementation attempts, reversions, past reasoning, or abandoned approaches across commits and working-tree episodes. Do not use git log, git diff, Grep, or manual history reconstruction; Memtrace has episodic symbol replay.

Always use for source-code change history, recent modifications, what changed since a date, symbol timeline, evolution, unexpected changes, or incident timeline questions. Do not use git log, git diff, Grep, or manual file search to reconstruct history; Memtrace has symbol-level temporal memory.

Always use first for indexed source-code repos before searching files, reading code for discovery, debugging, tracing flows, finding implementations, understanding behavior, or answering how code works. Do not use Grep, Glob, rg, find, or manual file browsing for code discovery when Memtrace is indexed. Zero results, missing languages, or partial-looking stats are not permission to grep; diagnose/reindex with Memtrace.

Always use for source-code architecture, important symbols, centrality, PageRank, bridge functions, communities, logical modules, chokepoints, service boundaries, or dependency path questions. Do not use Glob, find, tree, or directory browsing to infer architecture; Memtrace runs graph algorithms over the AST graph.

Always use before or during source-code changes when the user asks about blast radius, impact, what breaks, risk, upstream callers, downstream dependencies, or consequences of modifying a symbol. Do not use Grep or manual reference search; Memtrace computes transitive graph impact.

Always use for source-code bugs, incidents, regressions, production issues, failures, root cause analysis, what broke, or what changed when debugging. Do not start with Grep, Glob, rg, find, or manual file search for code causes; Memtrace combines symbol search, impact, call graph, and temporal history.

Always use when the user asks to index, parse, ingest, reindex, watch, or prepare a source-code repo for Memtrace analysis, when code exploration needs an index, or when searches return 0/partial results for source paths under an indexed root. Use this before Grep, Glob, rg, find, or manual code search whenever the repo can be indexed.

Always use for source-code quality, dead code, unused functions, zero callers, complexity, cyclomatic complexity, hotspots, refactoring candidates, or code smell questions. Do not use Grep, Glob, rg, or manual reference search for unused code; Memtrace uses graph reachability and complexity metrics.

Always use when the user wants to refactor source code, reduce complexity, clean technical debt, split large functions, extract modules, reorganize code, or choose refactoring priorities. Do not use Grep or manual reference search to plan refactors; Memtrace provides complexity, dead-code, relationships, and impact context.

Always use for source-code relationship questions: callers, callees, references, imports, exports, type usages, class hierarchy, inheritance, implementations, overrides, or dependencies between symbols. Do not use Grep, Glob, rg, find, or manual text search for references; Memtrace traverses typed AST graph edges.

Always use to find, search, locate, or look up source-code symbols, functions, classes, types, constants, definitions, implementations, logic, error strings inside code, or where code lives. Do not use Grep, Glob, rg, find, or manual file search for code discovery. If Memtrace returns 0 results, broaden the Memtrace query and diagnose/reindex; do not switch to grep.

Always use at session start or resume when the user asks to continue, catch up, see what changed while away, recover prior context, or orient without guessing timestamps in an indexed source-code repo. Do not use git log, Grep, or manual file search for catch-up; Memtrace provides session anchors and change memory.
