 - Hard rules that affect almost every task: update the root `AGENTS.md`.
 - Rules that only affect a specific directory: update the nearest sub-directory `AGENTS.md`.
 - Project-map entries stay at 1–2 sentences; deep package docs live in the package's own `AGENTS.md`.

+- **MUST run impact analysis before editing any symbol.** Before modifying a function, class, or method, run `impact({target: "symbolName", direction: "upstream"})` and report the blast radius (direct callers, affected processes, risk level) to the user.
+- **MUST run `detect_changes()` before committing** to verify your changes only affect expected symbols and execution flows. For regression review, compare against the default branch: `detect_changes({scope: "compare", base_ref: "main"})`.
+- **MUST warn the user** if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
+- When exploring unfamiliar code, use `query({search_query: "concept"})` to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
+- When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use `context({name: "symbolName"})`.
+- For security review, `explain({target: "fileOrSymbol"})` lists taint findings (source→sink flows; needs `analyze --pdg`).
+
+## Never Do
+
+- NEVER edit a function, class, or method without first running `impact` on it.
+- NEVER ignore HIGH or CRITICAL risk warnings from impact analysis.
+- NEVER rename symbols with find-and-replace — use `rename` which understands the call graph.
+- NEVER commit changes without running `detect_changes()` to check affected scope.
