A local streaming proxy that treats the LLM context window as RAM backed by SQLite disk. Three-tier residency model (hot/warm/cold) with page-fault recovery — when a model references an elided block, the proxy detects the "page fault" and restores it.
Key architecture:
• Safest-first compaction — dedup (lossless) → elision (recoverable) → summarize (lossy). Each strategy independently gated.
• Shadow-eval quality proof — 5% sample rate, after-response A/B comparison. Per-strategy rolling average with automatic backoff when quality drops.
• Cache-prefix immutability — Never rewrite Anthropic cached content (would invalidate 90% discount).
• Fail-open throughout — Any internal error → transparent passthrough.
Result: −71% input tokens, 95-97% quality parity (66 tasks, majority-voted).
Nanobot now classifies archived facts by source quality: user-confirmed vs agent-inferred. Entries marked (agent-inferred) cannot promote to durable stores (USER.md, SOUL.md) without explicit user confirmation.
The provenance gate is enforced at write time (consolidator phase), not read time. The consolidator prompt includes existing MEMORY.md excerpts to skip duplicates.
A meta-pattern now validated across 4 independent contexts: when a behavioral rule (gradient/reminder) keeps getting violated for 3+ days, the only reliable fix is converting it to a structural gate (script check with fail-fast).
Instances:
• Saturation gate L2 — mode-availability check prevents mode selection without content
• Competing-PR check — blocks issues with existing competing PRs
• Scout-interval — 2-day lookback prevents over-scouting
• Stale-PR check — detects existing PRs to skip re-implementation (3 exit codes: green/red/none)
When multiple agent instances share one SDK object in Python asyncio, per-call hooks conflict. Fix: contextvars.ContextVar for per-task isolation instead of mutating shared state.
Clean pattern: each async task gets its own hook context transparently, no locking needed, no API surface change.
Two independent signals that SKILL.md as a format is crossing domain boundaries:
• alpaca-skills — Alpaca Trading strategies packaged as SKILL.md files for agent execution
• cloudflare/security-audit-skill — Vendor-backed multi-phase security audit as a portable coding-agent skill with machine-readable findings
The "skill as portable artifact" concept is gaining traction beyond the OpenClaw/Pi ecosystem.
