 # agent-tools

-smal tools for ai agents
+Small, self-contained CLI tools built for **AI agents** to use during
+development work. Every tool is a single static Go binary with a
+text-first interface: input formats an agent can read and write
+directly, and output (names, errors, previews) explicit enough that the
+agent understands the result without opening an image viewer.
+
+| Tool | Binary | What it does |
+|------|--------|--------------|
+| [`pixel-sprite-maker/`](pixel-sprite-maker/) | `spritec` | Turns `.sprite` text files (palette + character grid) into PNG/JPG/SVG pixel art, up to 256x256 px per sprite. Combines several sprites into sprite sheets / animation strips whose **file names document the layout** (`walk_8x8_4x1.png` = 8x8 px frames, 4 columns, 1 row). |
+| [`mesh-tool/`](mesh-tool/) | `mesht` | Creates, inspects and edits 3D models (OBJ + STL). ASCII multi-view rendering + measurements (bbox, volume, watertightness) let an agent *see* a model, edit it (scale/rotate/mirror/merge/primitives) and verify the result. |
+
+Each tool has its own folder, its own README with the full format/CLI
+reference, its own tests and its own dev branch (`dev/<tool>`).
+
+## Building
+
+```bash
+# Arch/Garuda prerequisite:
+sudo pacman -S go
+
+cd <tool>/ && go build -o build/<binary> .    # per tool
+go test ./...                                 # per tool
+```
+
+VS Code: **Terminal → Run Build Task** — `build` builds every tool into
+its own `<tool>/build/` folder; per-tool `build <tool>` and
+`test <tool>` tasks also exist.
+
+## CI / releases
+
+`.gitea/workflows/release.yml` runs on every push to `master`/`main` on
+the self-hosted runner: tools whose folders changed are tested, built
+for **linux x64 + arm64** (the Pi5), and published to a rolling
+release per tool on the repo's release page:
+
+- tag `pixel-sprite-maker-latest` → assets `spritec-linux-x64`, `spritec-linux-arm64`, `checksums.txt`
+- tag `mesh-tool-latest` → assets `mesht-linux-x64`, `mesht-linux-arm64`, `checksums.txt`
+
+A manual `workflow_dispatch` run builds all tools regardless of diffs.
+
+## Branch layout
+
+- `main` — stable, releases are built from here
+- `dev/pixel-sprite-maker`, `dev/mesh-tool` — per-tool development branches

+# agent-tools — plan
+
+## Goal
+
+A collection of small, agent-friendly CLI tools. The common thread:
+**text in, verifiable artifacts out**. An agent should be able to author
+the input format directly, predict what the output will look like, and
+verify results without a GUI.
+
+## Stack
+
+- Go (single static binaries, zero deps, trivial cross-compile to the
+  Pi5's arm64 runner), one Go module per tool.
+- Targets: linux x64 + linux arm64.
+
+## Deploy target
+
+Pattern A (distributable binaries): rolling `<tool>-latest` release per
+tool on Gitea, built by `.gitea/workflows/release.yml` on push to
+master/main. Only tools whose folders changed get rebuilt.
+
+## Milestones
+
+1. ✅ `pixel-sprite-maker` (`spritec`): .sprite text format → PNG/JPG/SVG,
+   sprite sheets with self-documenting file names, terminal preview.
+2. ✅ `mesh-tool` (`mesht`): OBJ/STL create/inspect/edit with ASCII
+   multi-view rendering, measurements and watertightness checks.
+3. ✅ Per-tool VS Code build tasks → `<tool>/build/`.
+4. ✅ CI: changed-tool detection + per-tool rolling releases.
+
+## Roadmap / expansion ideas (not agreed yet)
+
+- spritec: palette import from image files, GIF export for animations,
+  tile-map composer (map file referencing sprite tiles).
+- mesht: OBJ vertex-color support, simple boolean ops (union via
+  voxelization), PNG snapshot rendering, glTF export.
+- New tools: bitmap-font maker, sound-effect generator (sfxr-style text
+  presets), tiled-map (.tmx) writer.
+
+## Open questions
+
+- Versioned releases (`vX.Y.Z` tags per tool) on top of the rolling
+  `latest` — add when something depends on a pinned version.
