Code review from chatGPT app

[attogram]

This is a comprehensive and well-structured Bash script that enables a conversational interface with models running on Ollama, using CLI tool execution as plugins ("toolshed"). Here's a detailed code review broken down into strengths, issues, and recommendations.

---

✅ Strengths

🔧 Modularity

Each function has a clear single responsibility, e.g., getSystemPrompt*(), addMessage(), sendRequestToAPI(), etc.

Configurations are centralized using the configs array and handled cleanly.

📦 Tool Integration

Good support for modular "tools" via a JSON definition and a shell script. This design makes it easy to add new capabilities.

💬 Prompt Management

Tracks conversation history using a JSON array of messages.

Allows multi-line input via /multi and raw shell commands using !cmd.

🧪 Debugging Support

Simple but effective debug() and debugJson() functions toggle via /config verbose on.

🧠 Structured Thinking

Incorporates "thinking" steps in assistant responses via showThinking().

⚠️ Issues and Weaknesses

1. Improper Use of continue in processUserCommand

continue should only be used inside loops.

continue

You likely meant return here. For example:

/config name value - set a config to new value

Change this:

setConfig "${commandArray[1]}" "${commandArray[2]}"
continue

To:

setConfig "${commandArray[1]}" "${commandArray[2]}"
return 0

Applies to other places in processUserCommand.

---

2. Tool Execution Without Quoting

In:

toolResult="$($toolFile)"

If $toolFile contains spaces (e.g., in argument strings), it may fail.

✅ Safer:

toolResult="$(bash -c "$toolFile")"

---

3. Race Conditions on toolResult

If tool output is large or error-prone, you should handle:

Exit status of tool execution

Stderr/stdout separation

✅ Example:

toolResult="$(bash -c "$toolFile" 2>&1)"
if [ $? -ne 0 ]; then
echo "Tool execution failed: $toolResult"
return
fi

---

4. Hard-Coded Tool Paths

Assumes all tools are in ./tools/toolName/run.sh.

✅ Suggest using:

local toolPath="${TOOLS_DIRECTORY}/${function_name}/run.sh"
if [ ! -x "$toolPath" ]; then
echo "Tool script not found or not executable: $toolPath"
return 1
fi

---

5. Missing JSON Escaping in Shell Tool Arguments

Tool arguments passed like this:

run.sh {json}

This will break if json contains quotes or special chars.

✅ Safer:

Write JSON to a temp file and pass the file path

Or use proper JSON escaping with printf '%q'.

---

💡 Suggestions for Improvement

A. Use ShellCheck

Run your script through ShellCheck. It’ll flag subtle quoting, logic, and portability issues.

---

B. Add Logging Levels (INFO, WARN, ERROR)

Currently only debug is supported. A logging helper like:

log() { echo -e "[INFO] $"; }
warn() { echo -e "[WARN] $" >&2; }
error() { echo -e "[ERROR] $*" >&2; }

Would improve readability and structure.

---

C. JSON Validation

Use jq empty to validate tool JSON definitions before loading:

cat "$definitionFile" | jq empty 2>/dev/null || {
echo "Invalid JSON in $definitionFile"
continue
}

---

D. Add Unit Tests (optional)

Create a tests/ folder with sample tools and model mocks to validate CLI behavior.

---

E. Graceful Ctrl+C

Consider catching SIGINT for cleanup:

trap 'echo; echo "🛑 Exiting..."; exit 0' SIGINT

---

✅ Overall Assessment

Category Score / Notes

Functionality ✅ Excellent. Core features work well.
Code Organization ✅ Clean modular functions
Error Handling ⚠️ Needs improvement in some areas
Shell Scripting Best Practices ⚠️ A few issues with continue, quoting
User Experience ✅ Thoughtful prompt, tools, and help UX
Extensibility ✅ High – easy to add tools or models

Would you like me to:

Refactor the script for safer tool execution?

Generate unit tests or a ShellCheck report?

Create a CLI help summary as Markdown?
