Felipe Cardoso	caf283bed2	feat(safety): enhance rate limiting and cost control with alert deduplication and usage tracking ... - Added `record_action` in `RateLimiter` for precise tracking of slot consumption post-validation. - Introduced deduplication mechanism for warning alerts in `CostController` to prevent spamming. - Refactored `CostController`'s session and daily budget alert handling for improved clarity. - Implemented test suites for `CostController` and `SafetyGuardian` to validate changes. - Expanded integration testing to cover deduplication, validation, and loop detection edge cases.	2026-01-03 17:55:34 +01:00
Felipe Cardoso	520c06175e	refactor(safety): apply consistent formatting across services and tests ... Improved code readability and uniformity by standardizing line breaks, indentation, and inline conditions across safety-related services, models, and tests, including content filters, validation rules, and emergency controls.	2026-01-03 16:23:39 +01:00
Felipe Cardoso	728edd1453	feat(backend): add Phase B safety subsystems (#63) ... Implements core control subsystems for the safety framework: **Action Validation (validation/validator.py):** - Rule-based validation engine with priority ordering - Allow/deny/require-approval rule types - Pattern matching for tools and resources - Validation result caching with LRU eviction - Emergency bypass capability with audit **Permission System (permissions/manager.py):** - Per-agent permission grants on resources - Resource pattern matching (wildcards) - Temporary permissions with expiration - Permission inheritance hierarchy - Default deny with configurable defaults **Cost Control (costs/controller.py):** - Per-session and per-day budget tracking - Token and USD cost limits - Warning alerts at configurable thresholds - Budget rollover and reset policies - Real-time usage tracking **Rate Limiting (limits/limiter.py):** - Sliding window rate limiter - Per-action, per-LLM-call, per-file-op limits - Burst allowance with recovery - Configurable limits per operation type **Loop Detection (loops/detector.py):** - Exact repetition detection (same action+args) - Semantic repetition (similar actions) - Oscillation pattern detection (A→B→A→B) - Per-agent action history tracking - Loop breaking suggestions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-03 11:28:00 +01:00
