Executing Plans

# Executing Plans

Execute the plan yourself, task by task, in this session: no implementer
subagent per task, no reviewer per task. One fresh-context review of the
whole branch at the end.

**Why inline:** Subagent-driven development pays for a fresh implementer
and a fresh reviewer on every task, each re-reading the codebase from zero.
Inline execution pays for one context (yours) plus one reviewer at the end.
What it gives up is a fresh context per task and a second pair of eyes per
task. This skill keeps what those two things bought, by other means: the
brief is the spec, the ledger is your memory, TDD is the per-task gate, and
the final reviewer is the second pair of eyes.

**Core principle:** The plan already did the thinking. Execute it exactly,
prove each step with a test you watched fail and then pass, and leave a
record that survives your own forgetting.

**Narration:** between tool calls, narrate at most one short line — the
ledger and the tool results carry the record.

**Continuous execution:** Do not pause to check in with your human partner
between tasks. They chose inline execution to spend less, not to answer
"should I continue?" after every task. Execute all tasks from the plan
without stopping.

**Rulings, not stalls.** Conflicts, ambiguities, plan defects — decide them.
The spec is the binding authority, the plan is its argument, and your
judgment settles what neither answers. Record every decision in the ledger
