Talkdown

Talkdown Skill

Talkdown is an AI-based execution language where Markdown documents are programs and LLMs are the runtime. Each .md file is a "function" with inputs, execution logic (AI prompts or real code), outputs, and routing to the next document — creating chainable, human-readable AI workflows.

Core Concepts

• Directive: An atomic, reusable task document (like a function)
• Process: A multi-step workflow that chains directives (like a program)
• Routing: Control flow — each document's output names the next document to execute
• ai code fence: A code block "executed" by LLM reasoning (not a traditional runtime)
• Hybrid execution: Mix real JavaScript code blocks with AI reasoning blocks in one document

When To Use This Skill

Use Talkdown when the user wants to:

• Create AI-driven workflows defined in Markdown
• Chain multiple LLM calls together with structured inputs/outputs
• Build reusable prompt templates with execution logic
• Create document-driven automation pipelines
• Define processes that mix code execution with AI reasoning

Deployment: Detect Runtime Environment

IMPORTANT: Before deploying, detect whether you are running inside Oboto or a generic environment.

How to detect Oboto

You are in Oboto if ANY of these are true:

• You have access to surfaceApi tools (create_surface, update_surface_component)
• You have access to write_file / read_file workspace tools
• You can create .routes/ files for the workspace content server
• The user is interacting with you through the Oboto chat interface

If Oboto → Deploy with Routes (Section A)

If Generic → Deploy CLI runner (Section B)

Section A: Oboto Deployment

When running inside Oboto, deploy Talkdown as workspace routes + an interactive surface.

Step 1: Deploy the Engine Files

Create these files in the user's workspace:

Step 2: Deploy the Directive Library

Create these files in talkdown/directives/:

talkdown/directives/decompose-task.md

---
title: Decompose Task
description: Breaks a complex task into smaller, ordered sub-tasks
inputs: [task]
outputs: [decomposed_tasks]
---

This directive decomposes a given task into a list of smaller, manageable sub-tasks.

## Inputs

- **task**: _string_ - The task to decompose into sub-tasks

## Execution

` ``ai
Analyze the given task and break it down:

1. Identify the main objectives and sub-objectives
2. Break down main objectives into atomic sub-tasks
3. Order sub-tasks by dependency (tasks that depend on others come later)
4. Estimate relative effort for each (small / medium / large)
5. Return a numbered list

Each sub-task should be concrete and actionable — not vague.
` ``

## Output

- **decomposed_tasks**: _array_ - Ordered list of sub-tasks with description and effort estimate

## Routing

Routing: none

talkdown/directives/validate-result.md

---
title: Validate Result
description: Validates a task result against a reference for quality and completeness
inputs: [task_result, result_reference]

---

Validates a task result against a reference. Returns whether the result meets quality standards.

## Inputs

- **task_result**: _string_ - The result to validate
- **result_reference**: _string_ - The reference standard to validate against

## Execution

` ``ai
Compare the task_result against the result_reference:

1. Check for equivalence in quality, detail, and completeness
2. If the result falls short, identify specific gaps
3. For each gap, create a concrete remediation task
4. If the result meets or exceeds the reference, confirm validation

Be specific about what's missing — vague feedback is not useful.
` ``

## Output

- **validation_status**: _boolean_ - true if validated, false if gaps remain
- **remaining_tasks**: _array_ - List of specific tasks to close gaps (empty if validated)

## Routing

Routing: none

talkdown/directives/generate-directive.md

title: Generate Directive
description: Meta-directive that generates new Talkdown directives from a description

## Inputs

- **name**: _string_ - The name of the directive to generate
- **description**: _string_ - What the directive should accomplish

## Execution

` ``ai
Generate a complete Talkdown directive in Markdown format with:

1. YAML frontmatter with title, description, inputs, and outputs
2. A preamble paragraph explaining the directive's purpose
3. An ## Inputs section listing each input with name, type, and description
4. An ## Execution section with an ai code block containing the task prompt
5. An ## Output section listing each output with name, type, and description
6. A ## Routing section (default: Routing: none)

The directive should be self-contained and executable by an LLM.
Wrap the complete directive in a markdown code block.
` ``

## Output

- **directive_markdown**: _string_ - Complete Talkdown directive as Markdown

## Routing

Routing: none

const method = (inputs.method || 'GET').toUpperCase();
const fetchOptions = { method, headers: inputs.headers || {} };
if (inputs.body && (method === 'POST' || method === 'PUT')) {
  fetchOptions.body = typeof inputs.body === 'string' ? inputs.body : JSON.stringify(inputs.body);
  fetchOptions.headers['Content-Type'] = fetchOptions.headers['Content-Type'] || 'application/json';
}
const res = await fetch(inputs.url, fetchOptions);
const body = await res.text();
context.outputs.response_status = res.status;
context.outputs.response_body = body;
` ``

## Output

- **response_status**: _number_ - HTTP status code
- **response_body**: _string_ - Response body

## Inputs

- **description**: _string_ - Natural language description of the data to model
- **format**: _string_ - Output format: json-schema, typescript, sql (default: json-schema)

## Execution

` ``ai
Generate a data model based on the description:

1. Identify all entities and their attributes
2. Determine data types for each attribute
3. Identify relationships between entities
4. Add constraints (required fields, unique keys, etc.)
5. Output in the requested format

Be thorough — include all reasonable fields even if not explicitly mentioned.
` ``

## Output

- **schema**: _string_ - The data model in the requested format

## Routing

Routing: none

talkdown/directives/generate-user-stories.md

---
title: Generate User Stories

` ``ai
You are a capable personal assistant. For the given request:

1. **Understand**: Parse the request and identify the core need
2. **Plan**: Create a step-by-step plan to fulfill the request
3. **Execute**: Work through each step, providing concrete outputs
4. **Summarize**: Provide a clear summary of what was done and any next steps

Be proactive — anticipate follow-up needs and address them.
Be specific — provide actual content, not just descriptions of what you'd do.
` ``

## Output

- **plan**: _array_ - Steps taken
- **result**: _string_ - The deliverable
- **next_steps**: _array_ - Suggested follow-up actions

## Routing

Routing: none

}

Step 5: Deploy Templates

Create talkdown/templates/directive.md and talkdown/templates/process.md using the templates from the directive library section above.

Step 6 (Optional): Build a Talkdown Surface

If the user wants a UI, create a surface with:

• A document browser listing all directives and processes
• An editor for writing/editing Talkdown documents
• A runner panel that executes documents and shows results
• A workflow visualizer showing routing chains

Use surfaceApi.fetchRoute('/api/talkdown') to list documents and surfaceApi.fetchRoute('/api/talkdown/documents/NAME') to load them.

Section B: Generic CLI Deployment (Non-Oboto)

When NOT running inside Oboto, provide a standalone CLI runner.

Create talkdown-cli.mjs (single-file runner)

Tell the user to create this file and run it with node talkdown-cli.mjs:

#!/usr/bin/env node
/**
 * Talkdown CLI — Standalone runner for any Node.js environment
 * Usage:
 *   node talkdown-cli.mjs run <document> [--dir ./docs] [--provider openai] [--input key=value]
 *   node talkdown-cli.mjs list [--dir ./docs]
 *   node talkdown-cli.mjs parse <file.md>
 *   node talkdown-cli.mjs init [--dir ./docs]
