I Fed Bug Reports to a Free AI Triage Bot
An open-source maintainer shares how a free AI bot sorts messy issue queues at 3 AM, complete with scripts, thresholds, and a decision table.

- Open-source maintainer tests a free AI bot to sort messy bug queues automatically
- System runs via a zero-dependency script with a cron job scheduled at 3 AM
- Limits classification to four buckets with confidence labeling and no auto-closing
- Warning: Not suitable for PII data or queues with fewer than ten issues per week
Every software maintainer knows the morning routine. Opening the issue queue at 8 AM only to find fifteen tabs pointing to the exact same bug. One lacks any logs, another features a title resembling a ransom note, and a third turns out to be a feature request wearing a bug costume. Losing entire mornings to this queue prompted a small experiment: could a free AI sort the mess before human eyes ever touched it, without paid APIs or a GPU budget?
Issue triage is essentially pattern matching. Recognizing duplicate titles, missing stack traces, and feature requests disguised as bugs. While humans excel at spotting these patterns, the cost is cognitive attention—the scarcest resource in open-source development. A triage bot does not need to be perfect; it must be cheap, predictable, and loud when it makes a mistake. Free AI fits this role well as long as confidence levels are explicitly labeled.
The experiment operated on one strict rule: the bot routes, humans decide, and nothing gets closed automatically. The classifier was restricted to just four output buckets to reduce room for wrong guesses. The prompt forces the model to select a single bucket and justify it in one line. Furthermore, the model temperature is locked at 0 for repeatable, deterministic output, preventing the triage process from becoming erratic.

The core pipeline reads a JSON export of issues, classifies each item, and writes a report using a lightweight script with no dependencies beyond the standard requests library. The free server option hosts a nightly cron job running at 3 AM, precisely when cold starts do not matter. By the time the laptop opens in the morning, the entire queue is already sorted.
Confidence scores dictate subsequent actions, keeping the bot honest. No automated closures are permitted ever; the only standalone action the bot takes is posting a reviewable comment template. Running this script against a synthetic fixture of twelve issues successfully absorbed real-world failure modes into a reusable decision table.
"A free triage bot does not replace maintainers. It buys back the first hour of the morning."

Implementing free AI for preliminary bug triage demonstrates how solo maintainers can leverage lightweight automation to reclaim productivity without investing in costly infrastructure. Maintaining a strict human-in-the-loop policy—specifically avoiding autonomous issue closure—ensures that false positives generated by free-tier models do not disrupt project tracking or alienate contributors.
This pipeline is not a silver bullet. The author advises against running it for queues receiving fewer than ten issues weekly, as setup time outweighs time saved. It should also be avoided for security-sensitive content involving Personally Identifiable Information (PII) sent to external APIs. Projects bound by contractual SLAs should likewise steer clear of free tiers, proving that the script itself is the core asset while the hosting remains entirely replaceable.
