Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

FlowScript
Semantic notation for structured reasoning
21 typed markers for encoding decisions, tensions, blockers, causal chains, and temporal knowledge.
> Evolution note: FlowScript explored typed reasoning representation for AI agents — compression-as-cognition, temporal graduation, citation-validated patterns, immune system. These core concepts evolved into anneal-memory, a two-layer memory system for AI agents. The notation remains in active daily use for reasoning compression and knowledge encoding. This repo is maintained as a reference implementation and notation playground.
The Notation
FlowScript is a 21-marker semantic notation that both humans and AI parse natively. It sits between natural language (ambiguous, verbose) and formal logic (precise, unreadable). Start with three markers — ->, `> sub-ms reads, proven at scale || PostgreSQL -> rich queries, $15/month, ACID

What Evolved into anneal-memory
Through building FlowScript, we discovered that the core insights were more powerful than the syntax:
| FlowScript explored | anneal-memory delivers | |:---------------------|:----------------------| | Temporal graduation (1x → 2x → 3x → proven) | Citation-validated graduation with immune system | | Compression-as-cognition | Episodes compress into identity through consolidation | | Hash-chained audit trail | Tamper-evident compliance layer (EU AI Act) | | Anti-inbreeding defense | Graduation gate + principle demotion through citation decay | | Transport-layer wrapper | Compliance proxy vision (MCP transport interception) | | Six typed reasoning queries | Planned for anneal-memory CLI |
The notation barrier was real — developers won't learn a new syntax for memory. anneal-memory delivers the same cognitive architecture as a zero-dependency MCP server where agents use natural language.
