**The TencentDB-Agent-Memory repository formalizes operational knowledge into versioned Skills defined in [`MemoryCore/SKILL.md`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/MemoryCore/SKILL.md), capturing metadata, procedural workflows, troubleshooting logic, and success criteria required to install and manage the memory-tencentdb plugin.**

The TencentDB-Agent-Memory project treats database memory management as declarative code. By extracting installation steps, configuration parameters, error handling, and verification logic into a canonical Skill format, the repository enables automated agents and CI pipelines to reuse complex operational procedures across the OpenClaw ecosystem.

## Core Elements of a Reusable Skill

A Skill in TencentDB-Agent-Memory is a self-contained specification that declares everything required to execute a complete workflow. The canonical definition resides in [`MemoryCore/SKILL.md`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/MemoryCore/SKILL.md) and consists of nine distinct extractable components.

### Metadata Header

The Skill begins with a YAML frontmatter block containing `name`, `description`, and `version` fields. This header provides the unique identifier and human-readable purpose required for skill registration and versioning, located in [`MemoryCore/SKILL.md`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/MemoryCore/SKILL.md) (lines 1-5).

### Purpose and Scoping

- **Purpose Section**: Defines the high-level goal, such as providing local long-term memory without external services (lines 7-10).
- **Applicable Scenarios**: Enumerates trigger conditions—installation, configuration, or error handling—where the skill should activate (lines 11-16).
- **Non-Applicable Scenarios**: Explicitly defines limits to prevent misuse in unsupported contexts (lines 17-21).

### Standard Workflow

The procedural core consists of step-by-step blocks covering environment checks, package installation, minimal configuration, optional advanced settings, service restart, verification, and smoke testing. Each block functions as a reusable sub-skill that can be composed into larger pipelines (lines 22-69).

### Operational Reference Data

- **Troubleshooting Quick-Reference**: Catalogs common failure points and maps them to specific configuration keys that require inspection (lines 70-77).
- **Security & Compliance**: Establishes rules for secret handling and configuration drift prevention (lines 78-83).
- **Definition of Done (DoD)**: Specifies programmatic success criteria, such as plugin command exit codes, configuration file presence, and log markers containing `[memory-tdai]` (lines 84-92).
- **Delivery Script**: Provides ready-to-use phrasing for agents to report completion status to users or logging systems (lines 93-100).

## How Skills Are Parsed and Executed

The repository implements a four-stage consumption pipeline:

1. **Parsing**: YAML-aware tools extract the frontmatter header from [`SKILL.md`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/SKILL.md) to register the skill name and version.
2. **Orchestration**: The runtime engine—implemented in [`MemoryCore/src/utils/stateful-pipeline-manager.ts`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/MemoryCore/src/utils/stateful-pipeline-manager.ts)—evaluates each workflow step, executing embedded Bash snippets or invoking corresponding TypeScript/Node.js APIs.
3. **Verification**: After each major step, the engine validates against the DoD criteria; failures trigger the troubleshooting block.
4. **Reporting**: Upon success, the delivery script renders completion messages through the interface defined in the specification.

Because each block is declarative and tied to explicit success conditions, the same skill definition can be reused in documentation generators, automated assistants, and CI validation pipelines.

## Runtime Implementation Example

Below is a TypeScript snippet demonstrating how to programmatically load and execute a skill by parsing its metadata and executing contained Bash blocks:

```typescript
import yaml from 'js-yaml';
import { readFileSync } from 'fs';
import { execSync } from 'child_process';

// Load the skill definition from MemoryCore/SKILL.md
const skillPath = './MemoryCore/SKILL.md';
const raw = readFileSync(skillPath, 'utf8');
const frontMatter = raw.match(/^---\n([\s\S]*?)\n---/);
if (!frontMatter) throw new Error('Skill header missing');
const meta = yaml.load(frontMatter[1]) as { 
  name: string; 
  description: string; 
  version: string 
};

// Simple executor that runs each Bash block in order
function runSkill() {
  const steps = raw.split('```bash').slice(1)
    .map(block => block.split('```')[0].trim());
  for (const cmd of steps) {
    console.log(`Executing: ${cmd}`);
    execSync(cmd, { stdio: 'inherit' });
  }
}

// Run and verify completion
runSkill();
console.log(`✅ Skill "${meta.name}" (v${meta.version}) completed`);

```

This implementation parses the YAML header for metadata validation, extracts fenced Bash code blocks sequentially, and executes them using Node.js child process utilities.

## Supporting Files and Utilities

## Frequently Asked Questions

### What defines a reusable Skill in TencentDB-Agent-Memory?

A reusable Skill is a markdown file following the canonical structure defined in [`MemoryCore/SKILL.md`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/MemoryCore/SKILL.md) that encapsulates executable procedures for installing, configuring, and troubleshooting the memory-tencentdb plugin. It includes declarative metadata, step-by-step Bash workflows, and explicit Definition of Done criteria that allow automated systems to verify successful completion without human intervention.

### How does the Definition of Done (DoD) ensure reliability?

The DoD section in [`SKILL.md`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/SKILL.md) (lines 84-92) provides programmatic success criteria such as specific log markers (`[memory-tdai]`), command exit codes, and configuration file presence. The runtime engine in [`stateful-pipeline-manager.ts`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/stateful-pipeline-manager.ts) evaluates these criteria after each workflow step, ensuring that only fully validated states are considered successful and triggering troubleshooting workflows when assertions fail.

### Can existing Skills be migrated to newer versions?

Yes. The [`MemoryCore/SKILL-MIGRATION.md`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/MemoryCore/SKILL-MIGRATION.md) file provides formal guidelines for evolving skill definitions. It specifies how to update metadata headers, modify workflow steps, and handle breaking changes while preserving compatibility with existing agent configurations, ensuring that operational knowledge can be versioned and updated without breaking downstream automation.

### What diagnostic information can be exported from a Skill?

According to [`MemoryCore/SKILL-DIAGNOSTIC-EXPORT.md`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/MemoryCore/SKILL-DIAGNOSTIC-EXPORT.md), you can extract runtime state including execution logs, environment variables, configuration snapshots, and timing metrics from [`managed-timer.ts`](https://github.com/TencentCloud/TencentDB-Agent-Memory/blob/main/managed-timer.ts). This data enables post-hoc analysis of skill execution failures and performance optimization across different deployment contexts.
