feat(mem0-agent): read path, hooks, maintenance, CLI and skills
- pack.py: single-call context pack, budgeted, sanitized, cached, with served-id tracking that turns a citation into POSITIVE feedback - assist.py: error-signature lookup (never raw stdout, which returned 0 results in v1) - maintain.py: transactional consolidation (add merged -> verify -> delete sources) - transcript.py: JSONL parsing into non-overlapping windows via a cursor - cli.py: the twelve commands the hooks invoke; detached assist queues a block that the next prompt hook drains, keeping the hot path network-free - hooks generated from one spec; plugin manifest, MCP wiring, five skills Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

cannot:

1. HARD_DROP -- mechanical noise (task notifications, progress/ETA/epoch/loss

and windows whose normalized shape repeats one already seen) never leaves the

machine, at every aggressiveness level.
|

2. Repo content -- windows carrying excerpts of repository files (CLAUDE.md,
|
||||
README, configs). VALIDATION PROVED custom instructions CANNOT filter these:
|
||||
a pasted convention is textually indistinguishable from a stated convention,
|
||||
so the extractor happily stores it. Client-side omission is the only
|
||||
enforcement point. This rule is mandatory, not tunable.

|

Rules are lists of compiled patterns / predicates rather than if-branches so

that eval results can retune them by editing data. Everything here is pure and
