Changelog

0.4.0 - 2026-04-22

Added -- Context Intelligence Suite

  • deduplication.ts -- semantic deduplication engine using cosine similarity on TF-IDF term vectors. Detect and merge near-duplicate context entries with configurable similarity threshold. Includes deduplicateEntries() for batch dedup and findDuplicate() for single-entry checks.
  • priority.ts -- context priority scoring engine. Ranks entries by composite score of relevance (keyword overlap), recency (exponential time decay), and usage frequency (log-normalized). Configurable weights and half-life. Includes scoreEntries() and topK().
  • eviction.ts -- automatic context eviction policies. LRU (least recently used), LFU (least frequently used), and TTL (time-to-live) eviction with a unified evict() dispatcher. Enforces bounded context stores.
  • pii-guard.ts -- PII detection and auto-redaction policy guard. Detects emails, phone numbers, and SSNs with configurable actions: redact, warn, or block. Integrated into the kernel policy engine as pii_guard rule kind. Includes scanForPII() and scanMessages().
  • audit-trail.ts -- structured audit trail with query API. Collects KernelEvents into a queryable ledger with sequential numbering, flexible filters (session, event type, time range), pagination, and JSONL export/import. Includes createAuditHook() for automatic kernel integration.
  • shared-memory.ts -- cross-session context sharing via named memory pools. Publish/subscribe model for multi-agent coordination with membership tracking, pool capacity limits, and entry isolation. Includes createSharedMemoryRegistry(), publish(), subscribe(), readPool().
  • snapshots.ts -- context snapshots for session replay. Save and restore full context state (entries + usage records) with deep-copy isolation, session-scoped listing, and JSON export/import.
  • bulk.ts -- bulk operations for context stores. Batch insert, upsert, delete, get, and query with per-item success/failure tracking, pagination, and predicate-based filtering.
  • Added pii_guard policy rule kind to kernel policy engine and Zod schema.
  • Re-exported all new modules and types from src/core/index.ts and src/core/types.ts.

0.2.0 - 2026-04-01

Added -- Context Compaction Engine + Memory Prompts

  • compaction.ts -- full context compaction engine adapted from Claude Code's battle-tested system. Includes 9-section structured compact prompt, auto-compact threshold calculations (shouldAutoCompact, calculateTokenWarningState), summary formatting (formatCompactSummary strips analysis scratchpad, extracts <summary> block), and effective context window math. Constants: MAX_OUTPUT_TOKENS_FOR_SUMMARY (20k), AUTOCOMPACT_BUFFER_TOKENS (13k), WARNING_THRESHOLD_BUFFER_TOKENS (20k), MANUAL_COMPACT_BUFFER_TOKENS (3k).
  • memory-prompts.ts -- memory extraction and consolidation prompt builders. buildExtractMemoryPrompt generates a per-turn memory extraction instruction with manifest of existing files to avoid duplicates. Consolidation prompt builder for dream-cycle periodic memory organization.
  • Re-exported both modules from src/core/index.ts.

0.1.1

  • feat: validate KernelInput with Zod schema (rejects empty sessionId, empty messages, invalid roles, negative token counts)
  • fix: emit "failed" audit event before re-throwing when decide() encounters an error (the event type was defined but never used)
  • test: add 4 new tests covering input validation and failed-event emission
  • docs: retrofit README to SHIP_STANDARD format with validated quickstart and configuration table
  • chore: add MIT LICENSE file
  • chore: add repository metadata fields (homepage, bugs, repository) to package.json

0.1.0

  • Initial Context Kernel MVP
  • Core routing + token budget compression trigger
  • Policy guards (post-only, quiet-hours, secret guard)
  • Policy DSL rules (action_allowlist, quiet_hours, secret_regex)
  • Memory candidate extraction contract with confidence/source/writeback hints
  • OpenClaw + generic HTTP adapters
  • CLI runner
  • Test suite + CI/release workflows
