+# Docfill P0.5 Delivery Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Make the existing P0 CLI easier to hand to digital employees by adding delivery hygiene, runnable examples, a smoke script, and minimal Word split-placeholder support.
+
+**Architecture:** Keep one `docfill run` command and the existing internal package. Add only test fixture helpers and examples around the current API; do not add a template engine, web UI, or multi-command workflow.
+
+**Tech Stack:** Go, `excelize`, `modernc.org/sqlite`, standard shell for smoke testing.
+
+---
+
+### Task 1: Delivery Hygiene
+
+**Files:**
+- Create: `.gitignore`
+- Modify: `README.md`
+
+- [ ] Ignore local OS files, compiled binaries, test binaries, and example outputs.
+- [ ] Keep README focused on run/build/test/smoke usage.
+
+### Task 2: Word Split Placeholders
+
+**Files:**
+- Modify: `internal/docfill/docfill.go`
+- Modify: `internal/docfill/docfill_test.go`
+
+- [ ] Add a failing test for a Word placeholder split across adjacent `<w:t>` nodes in one paragraph.
+- [ ] Implement minimal rendering for split placeholders inside Word text nodes.
+- [ ] Keep existing contiguous placeholder behavior passing.
+
+### Task 3: Runnable Examples
+
+**Files:**
+- Create: `examples/README.md`
+- Create: `examples/excel-to-word/task.json`
+- Create: `examples/sqlite-to-excel/task.json`
+- Create: `scripts/smoke-fixtures/main.go`
+- Create: `scripts/smoke.sh`
+
+- [ ] Add two small configs that mirror real employee daily-report workflows.
+- [ ] Generate temporary fixture files from Go during smoke tests instead of storing binary Office files in git.
+- [ ] Smoke test builds the CLI, copies examples to a temp dir, generates fixtures, runs both example configs, and runs `go test -count=1 ./...`.
+
+### Task 4: Verify
+
+- [ ] Run `go test -count=1 ./...`.
+- [ ] Run `bash scripts/smoke.sh`.
+- [ ] Run `go build -o /tmp/docfill-p05 ./cmd/docfill`.
