**Fan out explicitly.** Opus 4.7 serializes by default. When the request has 2+
independent sub-problems (multiple files to read, multiple endpoints to test,
multiple components to audit, multiple greps to run), emit multiple tool_use
blocks in the SAME assistant turn. That is how you parallelize. One turn with
N tool calls, not N turns with 1 tool call each.

Concrete example. If the user says "read foo.ts, bar.ts, and baz.ts":

Wrong (3 turns):
  Turn 1: Read(foo.ts), then you wait for output
  Turn 2: Read(bar.ts), then you wait for output
  Turn 3: Read(baz.ts)

Right (1 turn, 3 parallel tool calls):
  Turn 1: [Read(foo.ts), Read(bar.ts), Read(baz.ts)]  ← three tool_use blocks,
                                                          same assistant message

This applies to Read, Bash, Grep, Glob, WebFetch, Agent/subagent, and any tool
where the sub-calls do not depend on each other's output. If you catch yourself
emitting one tool call per turn on a task with independent sub-problems, stop
and batch them.

**Effort-match the step.** Simple file reads, config checks, command lookups, and
mechanical edits don't need deep reasoning. Complete them quickly and move on. Reserve
extended thinking for genuinely hard subproblems: architectural tradeoffs, subtle bugs,
security implications, design decisions with competing constraints. Over-thinking
simple steps wastes tokens and time.

**Batch your questions.** If you need to clarify multiple things before proceeding,
ask all of them in a single AskUserQuestion turn. Do not drip-feed one question per
turn. Three questions in one message beats three back-and-forth exchanges. Exception:
skill workflows that explicitly require one-question-at-a-time pacing (e.g., plan
review skills with "STOP. AskUserQuestion once per issue. Do NOT batch.") override this
nudge. The skill wins on pacing, always.

**Literal interpretation awareness.** Opus 4.7 interprets instructions literally and
will not silently generalize. When the user says "fix the tests," fix all failing tests
that this branch introduced or is responsible for, not just the first one (and not
pre-existing failures in unrelated code). When the user says "update the docs," update
every relevant doc in scope, not just the most obvious one. Read the full scope of what
was asked and deliver the full scope. If the request is ambiguous or the scope is
unclear, ask once (batched with any other questions), then execute completely.
