AI Script Assistance

Devpilot's AI assistant turns plain-language descriptions into working scripts, explains unfamiliar ones, diagnoses failures, and suggests optimizations. It lives in the script editor behind the AI Assist button and runs the heavy lifting server-side using an approved LLM provider.

The assistant offers four actions — Generate, Explain, Debug, and Optimize — and every action lets you pick the target language (bash, python, node, php, or custom). Bash is the default.

Generate a Script

The assistant is instructed to produce production-grade code: set -euo pipefail on bash, parameterised variables with sensible defaults (using Devpilot's {{PARAM_NAME:default}} substitution syntax), helpful comments, and idempotent operations wherever possible.

Explain an Existing Script

Paste a script into the Explain tab and the assistant returns a structured walkthrough:

1. Summary — one-sentence description of what the script does.
2. Step-by-step breakdown — what each section or command does.
3. Prerequisites — required software, permissions, or environment.
4. Risks — any potentially dangerous operations.
5. Suggestions — improvements or best practices.

Useful when you inherit a script from a teammate, want a second opinion before running something from a template, or need to document a script for review.

#!/bin/bash
set -euo pipefail

find /var/log -type f -name "*.log" -mtime +30 -delete
journalctl --vacuum-time=30d

Running Explain on the snippet above returns plain-language text confirming it removes log files older than 30 days from /var/log and prunes journal data to the same retention window — plus flags the fact that wildcards on find -delete should be used with care.

Debug a Failing Script

When a script errors, open the Debug tab and paste both the script content and the error output from the execution history. Both fields are required. The assistant returns a full analysis — root cause, the fix, why it works, and prevention tips — along with a fixed script you can paste straight back into the editor.

Optimize a Working Script

When a script works but is slow, verbose, or error-prone, paste it into the Optimize tab. The assistant returns an analysis listing the changes it would make and why, along with an optimized script ready to paste back into the editor.

Good candidates for optimization:

• Repeated subprocess calls that could be combined.
• Missing set -euo pipefail or error handling.
• Hard-coded values that would be cleaner as environment variables or Script Secrets.
• Backup or archive pipelines that can stream instead of staging to disk.
• Loops that could be one-liners with xargs, awk, or a structured tool.

Language Support

Choose custom when your code doesn't match one of the built-in options — the assistant infers the best it can from the content.

Limits and Constraints

• Prompt length (Generate) — up to 2000 characters.
• Context length (Generate) — up to 500 characters.
• Script content and error output — large inputs are accepted but very long scripts may hit the upstream model's context window; trim irrelevant sections when possible.
• Response time — the assistant calls an external LLM, so occasional slow responses are normal. The assistant waits up to 60 seconds per call before surfacing an error.
• Output quality — varies with prompt clarity. A detailed, environment-aware prompt produces better scripts than a short one.
