Documentation Gap

The thinking documentation tells users that GPT-OSS's reasoning trace "cannot be fully disabled" and only lists low, medium, high as valid think levels. However, the code defines validReasoningEfforts as ["high", "medium", "low", "none"] — the "none" option fully disables the trace.

Severity: high

Description

The thinking documentation tells users that GPT-OSS's reasoning trace "cannot be fully disabled" and only lists low, medium, high as valid think levels. However, the code defines validReasoningEfforts as ["high", "medium", "low", "none"] — the "none" option fully disables the trace. Users who want to turn off reasoning are told it's impossible when it's one parameter away.

  • The thinking docs list GPT-OSS with low, medium, high levels and state "the trace cannot be fully disabled" (thinking.mdx:12)
  • validReasoningEfforts in the config code includes "none" as a fourth valid value (droid.go:203)
  • isValidReasoningEffort validates against this list, confirming "none" is accepted at runtime (droid.go:205-207)
  • No documentation anywhere mentions "none" as a valid reasoning effort — searching docs for "none" in thinking/reasoning context returned zero results
  • This is a direct contradiction: the docs explicitly say it can't be done, the code explicitly supports it

@rick-github commented on GitHub (Feb 27, 2026):

the "none" option fully disables the trace.

This is wrong. Please do not post any more AI rubbish.
