The --decompose flag and supporting decomposer module had two
unfixable bugs (#1045): it crashed when ANTHROPIC_API_KEY was unset,
and it created multiple branches/PRs per issue, fragmenting history
and complicating review/merge. Removing the feature instead of
patching either bug.
- Delete packages/core/src/decomposer.ts and all re-exports
- Drop @anthropic-ai/sdk dependency from @composio/ao-core
- Remove --decompose / --max-depth options from ao spawn
- Remove decomposer field from ProjectConfig (zod default-strip
silently ignores existing decomposer: blocks in user yaml)
- Remove lineage / siblings from SessionSpawnConfig and the
prompt-builder Layer 4 block (only used by decomposer)
- Gut the matching backlog reactor branch in web/services.ts
so the polling path no longer hits the same bugs
- Remove decompose parameter from openclaw-plugin ao_spawn tool
- Drop decomposer mocks from web services.test.ts
