…uto-save Adds a friendly UX layer on top of the existing quota.py engine so users can cap spend per session or per day, in tokens or USD, and never lose work when a cap is hit. - /budget command (commands/core.py): view usage vs each cap as colored bars + %, or set one — /budget $5 (cost), /budget 200k (tokens, parses 200k/1.5m), /budget daily $20, /budget clear. --budget $5 / --budget 200k startup flag. - One budget per scope: a new cap REPLACES the other unit for that scope, so switching tokens<->USD just works and no stale cap silently keeps blocking. - Tight enforcement (no surprise overshoot): check_quota projects the next request's input and stops BEFORE the call if it would cross the cap; quota.output_room clamps that call's max_tokens to the remaining headroom — a tool-heavy turn can't blow 40k->49k past the budget anymore. - Proximity warnings at >=80% (yellow) / >=95% (red) end-of-turn. - On hit: agent yields QuotaPause (carrying which cap broke: key/scope/unit/ limit); the REPL auto-saves the session (session_latest.json + daily backup, the path /resume reads) and prints next steps. The "raise it" hint matches the breached unit (token cap -> /budget 40k, daily cost -> /budget daily $40). quota.py: parse_budget / fmt_amount / usage_vs_limits / warnings / output_room, projected check_quota, QuotaExceeded carries the breached cap. agent.py: QuotaPause + projection + output clamp. cheetahclaws.py: /budget registration, QuotaPause handling, --budget, near-limit warnings. 42-case tests/test_budget.py (isolated quota dir). Docs: README, features.md, reference.md, news.md. Defaults stay unlimited (interactive); daemon serve-mode guardrails unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
