+# 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
