llm 0.31.1
Frames a narrow technical bug fix as a routine, low-friction maintenance action — minimizing perceived complexity, risk, or significance.
View original on simonwillison.netOverview
A minor software patch (llm 0.31.1) fixes a JSON serialization bug in OpenAI Chat Completion endpoint handling when tool calls contain empty arguments, discovered during testing of the llm-meta-ai plugin.
TL;DR
- Patch resolves edge-case JSON error triggered by empty tool arguments in OpenAI-compatible API calls
- Bug surfaced during internal testing of the experimental llm-meta-ai plugin
- No user-facing impact reported; no performance, security, or functional changes beyond error correction

Emphasizes resolution and context (testing) while minimizing scope, root cause analysis, affected systems, or broader implications; avoids any language suggesting instability, design flaw, or systemic integration risk.
What the story wants you to believe
This is a routine, well-understood, and cleanly resolved technical issue — not indicative of deeper integration fragility or design debt.
What it makes harder to question
Whether the underlying tool-calling specification is robust across providers, or whether similar edge cases remain untested.
How the spin works
Combines precise versioning, GitHub issue referencing, and contextual origin (testing another plugin) to signal rigor and transparency, while omitting ambiguity about scope or severity — creating disproportionate confidence in system resilience relative to the modest claim.
