v13.5.7

thedotmack/claude-memv13.5.7Jun 13, 2026by thedotmack

AI Summary

This release resolves a critical bug where an outdated `claude` CLI binary in the PATH would silently crash all observation processes. The update implements capability probing to identify compatible versions, prefers the newest one, and fails loudly with clear error messages if no compatible CLI is found.

Key Highlights

  • Fixes silent failures where old CLI binaries killed every observation process.
  • Probes every candidate for capability using specific flags rather than just checking existence.
  • Prefers the newest capable version and fails loud with remediation details.
  • Self-healing mechanism: CLI updates are picked up without a worker restart.

New Features

  • CLI capability testing during resolution.
  • 2KB stderr tail capture from SDK children.
  • Advisory build-size budgets (warnings instead of hard failures).

Full Release Notes

## What's Fixed

### Stale Claude CLI can no longer silently kill every observation (#2911)

If an abandoned npm-global `claude` binary sat earlier in PATH than your current install, every Observer spawn died instantly at flag parsing — worker healthy, zero observations, nothing in the logs. The resolver now:

- **Probes every candidate for capability**, not just existence: each CLI is tested with `--permission-mode dontAsk --version`, the exact flags claude-mem passes on every agent spawn. Binaries that reject them (older than the 2.1.x line) are skipped up front with a clear warning.
- **Prefers the newest capable version** — PATH order only breaks ties, so a stale binary can't shadow a current one.
- **Fails loud, never silent**: an explicit `CLAUDE_CODE_PATH` that's too old throws with the version and the remedy; if every CLI found is too old, the error names each path and version.
- **Self-heals on CLI updates**: successful resolutions are cached 15 minutes, failures are never cached — updating your CLI is picked up on the next observation without a worker restart.
- **Keeps a 2KB stderr tail** from SDK children, included in exit warnings (and read on `close`, so it's never truncated) — a CLI dying at flag parsing now says why at default log level.

### Build

- Bundle-size budgets are now advisory warnings instead of hard build failures.
