 Turn a memory note into a draft skill — the step that makes the memory *do*
 something rather than only be read.
 
+## Existing code (already implemented)
+
+**`crates/mem-core/src/lesson.rs`** already contains:
+
+| Function | What it does | Tests |
+|---|---|---|
+| `render_skill(tool, lessons)` | Generates `SKILL.md` with YAML frontmatter (`name`, `description`), per-lesson sections with `seen`/`last_seen`/`confidence`/`resolution`, and recurring-failure warnings | `skill_description_lists_symptoms_not_summary` |
+| `render_injection(hit, max_chars)` | Generates capped injection text for prompts | `injection_is_capped` |
+
+**`crates/mem-cli/src/lessons_cmd.rs`** already contains:
+
+| Command | What it does |
+|---|---|
+| `mem materialize` | Writes `skills/<tool>-failures/SKILL.md` per tool + `MEMORY.md` digest. Creates dirs, prints symlink instructions for Claude Code / pi. |
+
+## What remains to complete this task
+
+The existing code generates skills from **command-level lessons** (`Lesson` struct). This task requires:
+
+1. **Draft from L1/L2 memory notes** — `mem skill draft --from <project>/<query-id>` reads a GRU-Mem memory node, not a lesson
+2. **LLM-assisted conversion** — prompt the model to convert descriptive memory into procedural instruction using the rubric
+3. **`_drafts/` enforcement** — existing `mem materialize` writes directly to `skills/`; this task must write to `_drafts/` only
+4. **`generated_from: <sha>` provenance** — link back to the memory node
+5. **Integration tests** — `tests/it_skill_draft.rs` (7 assertions)
