fix(claude): detect --autocompact from claude --help instead of trusting the version floor - #2113
asasemahmed wants to merge 1 commit into
Conversation
…ing the version floor CLI 2.1.129 is above the 2.1.122 floor but rejects --autocompact as an unknown option, which fails every Claude turn. snapshot() now reads `claude --help` once per CLI version and records whether the flag is listed; turns use that result and fall back to the version floor only when the CLI has not been probed or the probe failed. The earlier detection from milind-soni#1213 was lost in a later merge, so this adds it back in a smaller form along with a regression test. The fake CLI now answers --help. Fixes milind-soni#1187

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Clear the cached support state before starting a new CLI help probe.
When snapshot() detects a new CLI version, it sets cliVersionChecked = true before awaiting claude --help. During that await, sendTurn() can read the previous cliHasAutocompact === true and append --autocompact. If the new CLI does not support that option, it can reject the turn.
Reset or atomically replace the cached support value at the probe boundary so sendTurn() cannot use the previous positive result while the probe is pending.

What changed
--autocompactversion floor (2.1.122) and still reject the flag with "unknown option", which fails every turn. The turn now usesclaude --helpto decide whether to pass it.snapshot()probesclaude --helponce per CLI version and records whether--autocompactis listed as an option. Turns use that result. If there is no probe result (a turn before any snapshot, or--helpfailed), they fall back to the existing version floor.server/testing/fake-claude-cli.ts) now answers--help. It lists the flag unlessFAKE_CLAUDE_AUTOCOMPACT=0orFAKE_CLAUDE_VERSIONis below 2.1.122, so the existing old-CLI and unsnapshotted-turn tests keep their meaning.Why
Fixes #1187. Since #1213's detection was dropped, current main passes
--autocompactto any CLI at or above 2.1.122, and the reporter's 2.1.129 rejects it. A regression test is the safeguard against it being lost again.How it was verified
