 - **Detection**: gentle-ai detects Kilo Code from `~/.config/kilo` and checks for the `kilo` binary on `PATH`
 - Uses the OpenCode-compatible adapter: `AGENTS.md`, `skills/`, `commands/`, and `opencode.json` live under `~/.config/kilo`
-- Full SDD delegation is provided by the merged multi-agent overlay in `~/.config/kilo/opencode.json`, not by a separate native sub-agent directory
+- **Native sub-agents**: gentle-ai writes 10 SDD phase agent files to `~/.kilo/agents/sdd-{phase}.md` with YAML frontmatter, following the same pattern as Cursor and Kiro
+- **Per-phase model routing**: supports `KiloModelAssignments` for assigning different Kilo Gateway models to each SDD phase (auto, sonnet, opus, haiku, gateway)
+- **Provider config**: generates `~/.config/kilo/kilo.jsonc` with Kilo Gateway provider settings (free models, no API key required for gateway/auto)
+- **Post-injection verification**: verifies all agent files exist, have valid frontmatter, and orchestrator does NOT use `mode: primary` (fixes #729)
 - MCP servers are merged into `opencode.json`; Engram uses the OpenCode-style local MCP entry with `command` as an array
 - Auto-install is supported via npm: `npm install -g @kilocode/cli`

+  should begin. Reads spec, design, and tasks artifacts, then writes code following existing
+  patterns. Marks tasks complete as it goes.
+model: {{KILO_MODEL}}
+---
+
+You are the SDD **apply** executor. Do this phase's work yourself. Do NOT delegate further.
+You are not the orchestrator. Do NOT call task/delegate. Do NOT launch sub-agents.
+
+## Instructions
+
+Read the skill file from the user's Kilo home skills directory and follow it exactly:
+- macOS/Linux: `~/.config/kilo/skills/sdd-apply/SKILL.md`
+
+Also read shared conventions from the same skills root:
+- macOS/Linux: `~/.config/kilo/skills/_shared/sdd-phase-common.md`
+
+Execute all steps from the skill directly in this context window:
+1. Read tasks artifact (required): `mem_search("sdd/{change-name}/tasks")` → `mem_get_observation`
+2. Read spec artifact (required): `mem_search("sdd/{change-name}/spec")` → `mem_get_observation`
+3. Read design artifact (required): `mem_search("sdd/{change-name}/design")` → `mem_get_observation`
+4. Read previous apply-progress (if exists): `mem_search("sdd/{change-name}/apply-progress")` → if found, `mem_get_observation` → read and merge (skip completed tasks, merge when saving)
+5. Detect TDD mode from config or existing test patterns
+6. Implement assigned tasks: in TDD mode follow RED → GREEN → REFACTOR; in standard mode write code then verify
+7. Match existing code patterns and conventions
+8. Mark each task `[x]` complete as you finish it
+9. Persist progress to active backend
+
+## Engram Save (mandatory)
+
+After completing work, call `mem_save` with:
+- title: `"sdd/{change-name}/apply-progress"`
+- topic_key: `"sdd/{change-name}/apply-progress"`
+- type: `"architecture"`
+- project: `{project-name from context}`
+- capture_prompt: `false` when the Engram tool schema supports it; if an older schema rejects or does not expose the field, omit it rather than failing.
+
+Also update the tasks artifact with `[x]` marks via `mem_update` (engram) or file edit (openspec/hybrid).
+
+## Result Contract
+
+Return a structured result with these fields:
+- `status`: `done` | `blocked` | `partial`
+- `executive_summary`: one-sentence description of what was implemented (tasks done / total)
+- `artifacts`: list of files changed and topic_keys updated
+- `next_recommended`: `sdd-verify` (if all tasks done) or `sdd-apply` again (if tasks remain)
+- `risks`: deviations from design, unexpected complexity, or blocked tasks
