# Send baml-codegen to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "baml-codegen", "name": "baml-codegen", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/killerapp/baml-codegen", "canonicalUrl": "https://clawhub.ai/killerapp/baml-codegen", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/baml-codegen", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=baml-codegen", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "assets/agents/README.md", "assets/classification/README.md", "assets/extraction/README.md", "assets/integrations/README.md", "assets/rag/README.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "baml-codegen", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-11T17:57:46.026Z", "expiresAt": "2026-05-18T17:57:46.026Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=baml-codegen", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=baml-codegen", "contentDisposition": "attachment; filename=\"baml-codegen-2.0.0.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "baml-codegen" }, "scope": "item", "summary": "Item download looks usable.", "detail": "Yavira can redirect you to the upstream package for this item.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/baml-codegen" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/baml-codegen", "downloadUrl": "https://openagent3.xyz/downloads/baml-codegen", "agentUrl": "https://openagent3.xyz/skills/baml-codegen/agent", "manifestUrl": "https://openagent3.xyz/skills/baml-codegen/agent.json", "briefUrl": "https://openagent3.xyz/skills/baml-codegen/agent.md" } } ``` ## Documentation ### BAML Code Generation Generate type-safe LLM extraction code. Use when creating structured outputs, classification, RAG, or agent workflows. ### Golden Rules NEVER edit baml_client/ - 100% generated, overwritten on every baml-cli generate; check baml_src/generators.baml for output_type (python, typescript, ruby, go) ALWAYS edit baml_src/ - Source of truth for all BAML code Run baml-cli generate after changes - Regenerates typed client code for target language ### Philosophy (TL;DR) Schema Is The Prompt - Define data models first, compiler injects types Types Over Strings - Use enums/classes/unions, not string parsing Fuzzy Parsing Is BAML's Job - BAML extracts valid JSON from messy LLM output Transpiler Not Library - Write .baml → generate native code (Python/TypeScript/Ruby/Go), no runtime dependency Test-Driven Prompting - Use VS Code playground or baml-cli test to iterate ### Workflow Analyze → Pattern Match (MCP) → Validate → Generate → Test → Deliver ↓ [IF ERRORS] Error Recovery (MCP) → Retry ### BAML Syntax ElementExampleClassclass Invoice { total float @description("Amount") @assert(this > 0) @alias("amt") }Enumenum Category { Tech @alias("technology") @description("Tech sector"), Finance, Other }Functionfunction Extract(text: string, img: image?) -> Invoice { client GPT5 prompt #"{{ text }} {{ img }} {{ ctx.output_format }}"# }Clientclient GPT5 { provider openai options { model gpt-5 } retry_policy Exponential }Fallbackclient Resilient { provider fallback options { strategy [FastModel, SlowModel] } } ### Types Primitives: string, int, float, bool | Multimodal: image, audio Containers: Type[] (array), Type?
