# Markitect Tool Functional Requirements Specification V0.1

## markitect-tool

---

## 1. System Overview

markitect-tool is a **markdown-native toolkit and CLI** that enables users and systems to **parse, validate, transform, query, and generate markdown-based knowledge artifacts**.

This FRS defines the **externally observable functional behavior** of the system.

---

## 2. Actors and Interfaces

### 2.1 Primary Actors

* **User (Human Operator)** via CLI (`mkt`)
* **Automation System (`atm`)** via CLI or API
* **LLM Agent (`agt`)** via API or CLI orchestration
* **External Systems** integrating via programmatic interface

---

### 2.2 System Interfaces

* CLI interface (`mkt <command>`)
* Programmatic API (library usage)
* File system (markdown documents and configuration files)

---

## 3. Functional Requirements

---

## 3.1 Markdown Parsing and Structuring

### FR-001: Parse Markdown into Structured Representation

**Description:**
The system must parse markdown documents into a structured, machine-interpretable representation.

**Input:**

* Markdown file(s)

**Output:**

* Structured representation (accessible via CLI/API)

---

### FR-002: Preserve Structural Elements

The system must preserve:

* Sections and headings
* Metadata (e.g. frontmatter)
* Content blocks

in the structured representation.

---

## 3.2 Schema Definition and Validation

### FR-010: Define Schema from Input

The system must allow users to define or derive schemas from markdown documents.

---

### FR-011: Validate Documents Against Schema

**Input:**

* Markdown document(s)
* Schema definition

**Output:**

* Validation result indicating compliance or violations

---

### FR-012: Report Validation Results

The system must provide:

* Clear identification of violations
* Location/context of errors

---

## 3.3 Transformation and Composition

### FR-020: Transform Markdown Documents

The system must allow transformation of markdown documents based on defined rules or operations.

---

### FR-021: Compose Documents from Multiple Sources

The system must support combining multiple markdown inputs into a single output document.

---

### FR-022: Support Content Inclusion (Transclusion)

The system must allow content from one document to be included in another.

---

## 3.4 Query and Extraction

### FR-030: Query Structured Content

The system must allow querying of structured representations of markdown documents.

---

### FR-031: Extract Content Based on Criteria

**Input:**

* Query parameters

**Output:**

* Matching content or elements

---

## 3.5 Templating and Generation

### FR-040: Generate Markdown from Templates

The system must generate markdown documents based on:

* Input content
* Templates and/or rules

---

### FR-041: Support Rule-Based Generation

The system must allow generation driven by defined rules expressed in markdown or configuration.

---

### FR-042: Support LLM-Assisted Generation

The system must support generation workflows that incorporate LLM-based processing.

(Note: LLM usage is optional and externally provided.)

---

## 3.6 Automation and Workflow Execution

### FR-050: Execute Operations via CLI

The system must expose all core functions via CLI commands.

---

### FR-051: Support Batch Processing

The system must allow operations to be applied to multiple documents in a single execution.

---

### FR-052: Support Repeatable Workflows

The system must allow the same operation to be executed repeatedly with consistent results for identical inputs.

---

## 3.7 Configuration Handling

### FR-060: Load Configuration

The system must load configuration from:

* Files (e.g. project-level configuration)
* Environment

---

### FR-061: Apply Configuration to Operations

The system must apply configuration consistently across operations.

---

## 3.8 Caching and Incremental Processing

### FR-070: Cache Processing Results

The system must store intermediate or final results to avoid redundant computation.

---

### FR-071: Detect Changes

The system must detect changes in input data and reprocess only affected parts.

---

## 3.9 Error Handling

### FR-080: Provide Structured Errors

The system must return structured error information for:

* Invalid input
* Schema violations
* Execution failures

---

### FR-081: Avoid Silent Failures

The system must not silently ignore errors that affect output correctness.

---

## 4. Functional Constraints

* All functions must operate on **markdown-based input/output**
* LLM-assisted functions must degrade gracefully when unavailable
* Operations must not require persistent system infrastructure

---

## 5. Traceability

| PRD Concept                      | FRS Coverage  |
| -------------------------------- | ------------- |
| Structured markdown manipulation | FR-001–FR-022 |
| Schema validation                | FR-010–FR-012 |
| Querying and extraction          | FR-030–FR-031 |
| Templating and generation        | FR-040–FR-042 |
| CLI and automation               | FR-050–FR-052 |
| Configuration                    | FR-060–FR-061 |
| Efficiency via caching           | FR-070–FR-071 |

## 6. Acceptance Perspective

The system satisfies this FRS when:

* Each function can be invoked via CLI or API
* Outputs match defined input–output expectations
* Validation, transformation, and generation behaviors are observable and verifiable
* Errors are explicit and traceable
