From 1c36fc19680a49a0da82edb4624f2c15e556b6ec Mon Sep 17 00:00:00 2001 From: Frank Schwenk Date: Sun, 12 Jul 2026 11:32:01 +0200 Subject: [PATCH 01/14] docs: add RECIPES.md declarative pipeline recipes Catalog of single-step and composite/pipeline recipes for agents to expand into pipelines, with human notes, recipe inclusion, and xcf_stack.

Named building blocks for creating or editing pipelines in `pipelines/.py`. Load via `@RECIPES.md` in Cursor when working on pipelines. + +--- + +## 1. Rules cheat sheet + +1. **What a recipe is** — a named list of declarative lines. Agents turn it into Python using modules from `imagepipeline/modules/`. +2. **Layer order** — in every `combine` / composite recipe, lines are listed **bottom layer → top layer** (first line = background, last line = foreground on top). +3. **Indentation** — recipe id on its own line; indented lines below are the layers/steps of that recipe. +4. **`combine` = composite** — a multi-line recipe produces one output image by stacking those layers. +5. **Two-layer vs three-layer** — the `composite` module accepts exactly 2 inputs. Three or more layers need chained composites (bottom pair first, then add the next layer on top): + + ```text + # 3 layers: A (bottom), B (middle), C (top) + combine + A + B + C + # → composite(A, B) then composite(result, C) + ``` + +6. **Shared expensive steps** — `rembg` runs once per pipeline and is reused. Recipe lines say `rembg`, but the agent must not re-run it for every composite. +7. **`xcf_stack` (GIMP export)** — stacks **all prior step outputs** (plus `input/` by default) into one `.xcf` per image with layers named after step ids. Usually the **last step** after all composites. Requires `gimp` on PATH. Not a layer inside a `combine` block — a separate finishing recipe. +8. **Placeholders** — `COLOR1`, `COLOR2`, `COLOR`, `STYLE`, `MAX_EDGE`, `PROMPT`, `MODEL`, `TEMPLATE_IMAGE`, etc. are filled in at pipeline creation time (from your prompt or constants at the top of the script). +9. **Colors** — hex for backgrounds (`#RRGGBB` or `#RRGGBBAA`). G'MIC filters need `R,G,B` tuples (see [GMIC color derivation](#6-gmic-color-derivation) below). +10. **Single-step vs composite vs pipeline** — one declarative line = one module step. Multiple indented lines in a **composite** recipe = layers (bottom → top). Multiple indented lines in a **pipeline** recipe = sequential steps (first step first, output feeds the next). +11. **Recipe inclusion** — an indented line that matches a **recipe id** from this file expands that recipe instead of inlining its steps: + - In a **pipeline** recipe (e.g. `colorsplash-watermark`): resolve the referenced recipe, then chain the next line on its output. + - In a **composite** recipe: layers stay declarative (layer descriptions, not recipe ids). Do not nest composite recipes as layers. + - Expand recursively; share expensive steps (`rembg`, etc.) once across all expanded recipes in the same pipeline. +12. **Notes (human only)** — freeform reminders for you. **Agents must ignore them entirely** when building pipelines: + - **Full-line note:** line starts with `#` (optional leading spaces) — not a layer, not a recipe id. + - **Inline note:** `# …` after a recipe id on the same line (everything from `#` onward is ignored). + - Notes may be German or English. They never become code, constants, or prompts. +13. **Quick read examples:** + + ```text + original-stereo-rembg # wie horseland 3d effekt + original + rembg with gmic: gcd_stereo_img … + rembg + ``` + + ```text + colorsplash + # team gallery default look + original as greyscale + rembg + ``` + + ```text + colorsplash-watermark + colorsplash + darktable style STYLE + ``` + +--- + +## 2. How agents use this file + +- Recipes are **names + declarative steps**, not Python. +- When creating or editing a pipeline: read `@RECIPES.md`, resolve named recipes, substitute placeholders, emit real `Pipeline` code. +- **Recipe inclusion:** if an indented line is a known recipe id (e.g. `colorsplash` inside `colorsplash-watermark`), look up that recipe, expand it, and use its output as the input for the next step. Expand recursively. Do not duplicate shared steps — one `rembg` (etc.) per pipeline when multiple included recipes need it. +- **Pipeline vs composite:** multiple indented lines that are **sequential steps or recipe refs** = pipeline recipe (chain). Multiple indented **layer** lines (original, rembg, backgrounds, gmic-on-rembg, …) = composite recipe (combine). When unsure: if any line is another recipe id, treat the parent as a pipeline recipe. +- **Ignore notes:** skip any line that is only a `#` comment (after indent trim). Strip inline `# …` suffixes on recipe-id lines. Do not copy note text into Python comments unless Fränky asks. +- **`xcf_stack`:** when a pipeline includes recipe `xcf-stack` (or the user asks for GIMP layers), append as the final step: `p.step("xcf_stack", inputs="input")`. The module auto-collects `prior_steps` from the runner — do not list every composite as explicit inputs. See `imagepipeline/modules/xcf_stack.py`. +- **Shared steps:** define `rembg` (and other expensive steps) **once** per pipeline and reference the step in composites — mirror `pipelines/pipeline_baxxter.py`. +- Follow the **Rules cheat sheet** above — especially layer order and chained composites. +- **3+ layers:** chain `composite` steps (see baxxter, crusaders, orange). + +--- + +## 3.

Do not nest composite recipes as layers. - - Expand recursively; share expensive steps (`rembg`, etc.) once across all expanded recipes in the same pipeline. -12. **Notes (human only)** — freeform reminders for you. **Agents must ignore them entirely** when building pipelines: - - **Full-line note:** line starts with `#` (optional leading spaces) — not a layer, not a recipe id. - - **Inline note:** `# …` after a recipe id on the same line (everything from `#` onward is ignored). - - Notes may be German or English.

How agents use this file +## Layer lines (example) -- Recipes are **names + declarative steps**, not Python. -- When creating or editing a pipeline: read `@RECIPES.md`, resolve named recipes, substitute placeholders, emit real `Pipeline` code. -- **Recipe inclusion:** if an indented line is a known recipe id (e.g. `colorsplash` inside `colorsplash-watermark`), look up that recipe, expand it, and use its output as the input for the next step. Expand recursively. Do not duplicate shared steps — one `rembg` (etc.) per pipeline when multiple included recipes need it. -- **Pipeline vs composite:** multiple indented lines that are **sequential steps or recipe refs** = pipeline recipe (chain). Multiple indented **layer** lines (original, rembg, backgrounds, gmic-on-rembg, …) = composite recipe (combine). When unsure: if any line is another recipe id, treat the parent as a pipeline recipe. -- **Ignore notes:** skip any line that is only a `#` comment (after indent trim). Strip inline `# …` suffixes on recipe-id lines. Do not copy note text into Python comments unless Fränky asks. -- **`xcf_stack`:** list every layer source in `inputs=[...]` (bottom → top). Include `"input"` for the original. The runner schedules `xcf_stack` after all listed steps complete. See `imagepipeline/modules/xcf_stack.py` and `pipelines/pipeline_rezepttest.py`. -- **Shared steps:** define `rembg` (and other expensive steps) **once** per pipeline and reference the step in composites — mirror `pipelines/pipeline_baxxter.py`. -- Follow the **Rules cheat sheet** above — especially layer order and chained composites. -- **3+ layers:** chain `composite` steps (see baxxter, crusaders, orange). - ---- - -## 3.
