Snider e90a84eaa0 feat: merge go-agent + go-agentic + php-devops into unified agent repo
Combines three repositories into a single workspace:
- go-agent → pkg/orchestrator (Clotho), pkg/jobrunner, pkg/loop, cmd/
- go-agentic → pkg/lifecycle (allowance, sessions, plans, dispatch)
- php-devops → repos.yaml, setup.sh, scripts/, .core/

Module path: forge.lthn.ai/core/agent

All packages build, all tests pass.

Explain

This command provides context-aware explanations for code, errors, and stack traces.

Usage

  • /core:explain file.php:45 - Explain code at a specific line.
  • /core:explain error "error message" - Explain a given error.
  • /core:explain stack "stack trace" - Explain a given stack trace.

Code Explanation (file:line)

When a file path and line number are provided, follow these steps:

  1. Read the file: Read the contents of the specified file.
  2. Extract context: Extract a few lines of code before and after the specified line number to understand the context.
  3. Analyze the code: Analyze the extracted code block to understand its purpose and functionality.
  4. Provide an explanation: Provide a clear and concise explanation of the code, including its role in the overall application.

Error Explanation (error)

When an error message is provided, follow these- steps:

  1. Analyze the error: Parse the error message to identify the key components, such as the error type and location.
  2. Identify the cause: Based on the error message and your understanding of the codebase, determine the root cause of the error.
  3. Suggest a fix: Provide a clear and actionable fix for the error, including code snippets where appropriate.
  4. Link to documentation: If applicable, provide links to relevant documentation that can help the user understand the error and the suggested fix.

Stack Trace Explanation (stack)

When a stack trace is provided, follow these steps:

  1. Parse the stack trace: Break down the stack trace into individual function calls, including the file path and line number for each call.
  2. Analyze the call stack: Analyze the sequence of calls to understand the execution flow that led to the current state.
  3. Identify the origin: Pinpoint the origin of the error or the relevant section of the stack trace.
  4. Provide an explanation: Explain the sequence of events in the stack trace in a clear and understandable way.
