Cloudless Sky

Agentic AI mesh without the cloud.

OSMP (Octid Semantic Mesh Protocol) is an open encoding standard for agentic AI instruction and computation exchange. It works across any channel — from a 51-byte LoRa radio packet to a high-throughput cloud inference pipeline — using the same grammar, the same dictionary, and the same decode logic.

No cloud required. No inference at the decode layer. No central authority.

Install

Terminal

pip install osmp                  # Python SDK
pip install osmp-mcp              # MCP server (Claude Desktop, Cursor, Claude Code)
npm install osmp-protocol         # TypeScript SDK
cargo add osmp                    # Rust SDK
go get github.com/octid-io/cloudless-sky/sdk/go/osmp

30-Second Example

server.ts

from osmp import encode, decode

sal = encode(["H:HR@NODE1>120", "H:CASREP", "M:EVA@*"])
# "H:HR@NODE1>120;H:CASREP;M:EVA@*"

text = decode(sal)
# "(clinical) heart rate above 120 at NODE1, then [clinical] casualty report,
#  then [emergency] evacuation at all nodes"

35 bytes on the wire. Decoded by dictionary lookup, not inference. Fits a single LoRa packet at maximum-range spreading factor. The same input produces field-for-field identical output in Python, TypeScript, Go, and Rust.

Why OSMP

When AI agents communicate in JSON over HTTP, the cost compounds at every hop.

config.json

{"action": "move", "agent": "BOT1", "waypoint": "WP1", "priority": "urgent"}

82 bytes of envelope before any content. Tokenization required. Inference required to parse. Fails completely at the 51-byte LoRa minimum payload.

Code

R:MOV@BOT1:WPT:WP1↺

21 bytes. Deterministic decode. Fits a single LoRa packet. No inference at the receiving node — the structured instruction is recovered by dictionary lookup.

What OSMP changes is the output format and the decode layer. Frameworks above it (MCP, A2A, ACP, CrewAI, AutoGen, LangGraph) stay the same. Transports below it (HTTP, LoRa, BLE, WiFi, Meshtastic, satellite) stay the same. The serialization step changes, and the decode becomes inference-free.

How Agents Use It

Two paths. Both run OSMP in production.

Path A — MCP (zero-config)

The agent connects to the OSMP MCP server and reads the osmp://system_prompt resource (~390 tokens, under 0.3% of a 200K context window). It learns the grammar, the dictionary, and the composition rules on connect.

Terminal

claude mcp add osmp -- osmp-mcp

The agent then calls osmp_compose with natural-language instructions. The deterministic pipeline returns SAL or NL_PASSTHROUGH if no opcode matches.

Path B — SDK (your own transport)

Add the Usage Doctrine to your LLM's system prompt. The model composes SAL via SALComposer.compose() (or your language's equivalent). Wire encode / decode / validate into your agent loop.

server.ts

from osmp import encode, decode, validate

sal = "H:HR@NODE1>120→H:CASREP∧M:EVA@*"
result = validate(sal, nl="If heart rate exceeds 120, file casualty report and evacuate all nodes.")

if result.valid:
    transmit(sal)  # your transport layer

The validator catches hallucinated opcodes, missing consequence classes, namespace-as-target errors, byte inflation, and regulatory dependency violations. Eight rules. No exceptions.

Mixed Environments — The SALBridge

Not every agent in your system speaks OSMP. The bridge handles the boundary.

server.ts

from osmp import bridge

b = bridge("MY_NODE")
b.register_peer("GPT_AGENT", attempt_fnp=False)

# Outbound: SAL decoded to NL, annotated with SAL equivalent
out = b.send("H:HR@NODE1>120;H:CASREP", "GPT_AGENT")
# "heart_rate at NODE1 exceeds 120; casualty_report
#  [SAL: H:HR@NODE1>120;H:CASREP]"

The bridge annotates outbound messages with SAL, seeding the remote agent's context window. When the remote agent starts producing valid SAL through exposure, the bridge transitions from FALLBACK to ACQUIRED.

OSMP does not spread by installation. It spreads by contact.

Macros

A registered macro is a pre-validated multi-opcode SAL chain template invoked via A:MACRO[name]. The receiver expands the macro deterministically by dictionary lookup — no inference, no ambiguity, no per-message composition cost. Two macro corpora ship today.

Meshtastic — 16 macros, telemetry at the radio edge

Pre-validated SAL templates for Meshtastic protobuf telemetry over LoRa. Bundled with osmp-mcp. Resolvable via osmp_macro_invoke from any MCP-connected agent.

Macro	Purpose
`MESH:DEV`	DeviceMetrics telemetry (portnum 67)
`MESH:ENV`	EnvironmentMetrics basic (portnum 67)
`MESH:AQ`	AirQualityMetrics (portnum 67)
`MESH:PWR`	PowerMetrics (portnum 67)
`MESH:HLTH`	HealthMetrics (portnum 67)
`MESH:STAT`	LocalStats (portnum 67)
`MESH:POS`	Position (portnum 3)
`MESH:NODE`	NodeInfo (portnum 4)
`MESH:ACK`	Message acknowledgment (portnum 1)
`MESH:ALRT`	Alert (portnum 11)
`MESH:TRACE`	Traceroute (portnum 70)
`MESH:WPT`	Waypoint (portnum 8)
`MESH:TALRT`	Temperature threshold alert rule
`MESH:BATLO`	Battery low threshold alert rule
`MESH:NOFF`	Node offline detection rule
`MEDEVAC`	Clinical MEDEVAC chain template — heart-rate threshold → casualty report → broadcast evacuation

EML — 89 macros, math on the wire

Pre-built eml(x, y) = exp(x) − ln(y) chain templates for 89 specific (namespace, opcode) pairs. Each entry has a 3-character shorthand ID, a function-class taxonomy, and a precision class. Cross-SDK byte-identical across Python, TypeScript, Go, and Rust. The MDR fingerprint (e88350b1...) and envelope-bounded fingerprint (8aa47bd5...) gate cross-SDK drift in CI.

server.ts

from osmp.eml_mdr import REGISTRY, macro_count, lookup

assert macro_count() == 89
m = lookup("EXP")
print(m.shorthand_id, m.description)   # "EXP" "exp(x) = eml(x, 1)"

rust

use osmp::{eml_macro_count, eml_mdr_lookup};

assert_eq!(eml_macro_count(), 89);
let m = eml_mdr_lookup("EXP").unwrap();

86 macros are in the bit-exact fingerprint corpus; 3 are envelope-bounded and verified separately against documented tolerance bounds. Full schema (chain templates, preprocessing rules, precision classes, envelope bounds) ships in each SDK's eml_mdr module. See docs/macros.md for the full per-macro catalog.

Custom registries

The macro architecture is open. Build your own corpus with the same (shorthand_id, chain_template, function_class, precision_class) shape and register it at runtime via the SDK's MacroRegistry. Per-corpus fingerprints surface in the FNP handshake so peers gate compatibility before exchanging macro-bound traffic.

MDR — Managed Dictionary Registry

Where macros encode what to do, MDR encodes what to look up. Domain-specific controlled-vocabulary corpora are packaged as D:PACK/BLK binaries — block-level zstd-compressed dictionaries that resolve a code to its definition without network access, on a microcontroller with 38 KB of SRAM, in single-digit milliseconds.

The wire instruction stays compact (H:ICD[J93.0]) while the receiver still recovers the full official text ("Spontaneous tension pneumothorax"). The dictionary travels with the device, not the message.

Three corpora ship today

Corpus	Source	Entries	Raw size	D:PACK/BLK	Reduction
ICD-10-CM	CMS FY2026	74,719 clinical codes	5.4 MB	477 KB	91.4%
ISO 20022	eRepository 2025-04-24	47,835 financial definitions	8.7 MB	1.2 MB	86.5%
MITRE ATT&CK	Enterprise v18.1	1,661 techniques / malware / threat groups	82 KB	20 KB	75.3%

All three D:PACK/BLK binaries fit in ESP32 flash. The H namespace (clinical), K namespace (financial), and S namespace (security) gain edge-local Layer 2 accessor resolution as a result. Verified across all 124,215 codes in Python, TypeScript, and Go.

Use it

From an MCP-connected agent:

Code

osmp_resolve(code="J93.0", corpus="icd10cm")
→ "Spontaneous tension pneumothorax"

osmp_resolve(code="pacs.008.001.13", corpus="iso_msg")
→ "FIToFICustomerCreditTransferV13: ..."

osmp_discover(code_prefix="T1059", corpus="mitre_attack")
→ [{"id": "T1059", "name": "Command and Scripting Interpreter"}, ...]

osmp_batch_resolve(codes=["J93.0", "R00.1", "I25.10"], corpus="icd10cm")
→ {"J93.0": "...", "R00.1": "...", "I25.10": "..."}

From the Python SDK:

server.ts

from osmp.protocol import BlockCompressor

bc = BlockCompressor()
bc.load("mdr/icd10cm/MDR-ICD10CM-FY2026-blk.dpack")
result = bc.resolve("J93.0")
# "Spontaneous tension pneumothorax"

From TypeScript:

server.ts

import { resolveBlk } from "osmp-protocol";

const result = resolveBlk("mdr/icd10cm/MDR-ICD10CM-FY2026-blk.dpack", "J93.0");

From Go:

bc := osmp.NewBlockCompressor()
bc.Load("mdr/icd10cm/MDR-ICD10CM-FY2026-blk.dpack")
result, _ := bc.Resolve("J93.0")

Layer 2 accessor pattern

MDR pairs with the spec's Layer 2 accessor pattern: bracket-enclosed slot values from external open-ended registries. H:ICD[R00.1], H:SNOMED[concept_id], H:CPT[99213], K:ISO[MessageDefinitionIdentifier], S:ATTCK[T1059]. The bracket value is exempt from the single-character encoding rule — native code values pass through verbatim. MDR makes those native values resolvable at the receiver without network access; the wire instruction stays the same shape whether MDR is loaded or not.

Cross-basis compatibility

Per ADR-004, the FNP handshake exchanges a basis fingerprint that includes the MDR composition. Two nodes with equal basis fingerprints have byte-identical intern tables and unlock SAIL binary mode for that corpus's content. Two nodes with different bases fall back to SAL — semantic round-trip is preserved; only the SAIL compression bonus on MDR-covered content is gated.

Custom corpora

The MDR architecture is open. Operators can pack their own domain corpora into D:PACK/BLK using the published format and ship them alongside the base ASD. Per-corpus fingerprints flow through the FNP handshake automatically — peers gate SAIL binary mode on basis agreement and fall back to SAL when bases differ.

Behavioral Compliance

Smaller on the wire means nothing if the LLM can't use it correctly. Cross-model testing confirms it can.

Model	JSON Compliance	SAL Compliance	Wire Reduction
Claude Sonnet 4	90%	95%	72%
GPT-4o	85%	88%	72%
GPT-4o-mini	88%	88%	72%

SAL's advantage concentrates in safety classification: JSON models identify the correct consequence class 75% of the time. SAL models identify it 100%, across every model tested. The glyph is a universal signal.

SDKs

All four SDKs are independently verified against the canonical test suite. The SHA-256 ASD fingerprint (9ecc507e2c24c4a7) is byte-identical across SDKs and gates cross-SDK drift in CI.

SDK	Install	Reference
Python	`pip install osmp`	sdk/python/ — reference implementation
TypeScript	`npm install osmp-protocol`	sdk/typescript/ — `fzstd` for D:PACK/BLK
Go	`go get .../sdk/go/osmp`	sdk/go/ — ASD compiled-in
Rust	`cargo add osmp`	sdk/rust/ — pre-1.0 (0.5.2); full feature parity (FNP packet codec, SAIL binary, SEC envelope with replay protection, ADP session protocol, EML chain wire codec + ParametricChain evaluator + corpus fingerprint), pure-Rust fdlibm port for cross-device byte-identical math, D:PACK zstd resolve on shipped corpora, ASD core + v16 + EML + 89-macro registry
MCP Server	`pip install osmp-mcp`	osmp_mcp/ — 19 tools, wraps Python SDK

D:PACK/BLK resolve is verified across all 124,215 domain codes (74,719 ICD-10-CM + 47,835 ISO 20022 + 1,661 MITRE ATT&CK) in Python, TypeScript, and Go.

EML — Mathematics on the Wire

OSMP encodes instructions. EML encodes mathematics. Both ship in the same package.

EML is a companion evaluator based on Odrzywołek (2026, arXiv:2603.21852): a single binary operator eml(x, y) = exp(x) − ln(y), together with the constant 1, generates the standard calculator function basis — exp, ln, sin, cos, sqrt, arithmetic — as compact expression trees.

A full sin(x) or sqrt(x) approximation fits in fewer than 100 bytes on the wire. The receiving node decodes the tree and evaluates it deterministically by composing eml in a loop — no math library dependency, byte-exact identical output across all four SDKs.

server.ts

from osmp.eml import get_base_chain, compound_linear_calibration
import math

get_base_chain("ln(x)").evaluate(math.e)              # 1.0
compound_linear_calibration().evaluate([2.0, 3.0, 1.0])  # a·x + b = 7.0

A constrained-channel instruction can carry its own math: a 51-byte LoRa frame can ship an OSMP instruction and the calibration polynomial, exponential decay curve, or sensor coefficient needed to interpret it — on any receiver, without firmware updates.

89 pre-built EML functions ship today — exp, ln, sin, cos, sqrt, sigmoid, GELU, attention scores, Lorentz gamma, Boltzmann factor, Sharpe ratio, and 79 more across 9 function classes. See the Macros section for the full list.

Two modes:

Fast (default) — fdlibm-derived, 1-ULP accurate. Correct for LoRa/BLE/edge-ML, drone swarm coordination, general scientific computation. Ships publicly.
Precision — crlibm-derived, correctly-rounded, audit-grade. For regulated industries (medical IEC 62304, aerospace DO-178C, nuclear IEC 61513), audit-grade finance, cryptographic protocol-frame hash inputs. Available under commercial license — contact ack@octid.io.

Cross-SDK fingerprint: e9a4a71383f14624472fe0602ca5e0ff1959e00b09725a62d584e1361f842c1b. Identical across Python / TypeScript / Go / Rust.

Architecture

Component	Function
SAL — Semantic Assembly Language	Human-readable symbolic instruction format
SAIL — Semantic Assembly Isomorphic Language	Binary wire encoding, isomorphic to SAL
ASD — Adaptive Shared Dictionary	356-opcode version-pinned compression dictionary
ADP — ASD Distribution Protocol	Dictionary delta synchronization across nodes
BAEL — Bandwidth-Agnostic Efficiency Layer	Adaptive encoding across any channel capacity
FNP — Frame Negotiation Protocol	Capability negotiation, FALLBACK/ACQUIRED states for non-OSMP peers
MDR — Managed Dictionary Registry	Domain corpora (ICD-10-CM, ISO 20022, MITRE ATT&CK) as D:PACK/BLK binaries
OP — Overflow Protocol	Message fragmentation, priority, graceful degradation
SALBridge	Boundary translation for non-OSMP peers; propagation by contact
SEC — Security Envelope	AEAD + Ed25519 authentication for mesh networks
SNA — Sovereign Node Architecture	Autonomous edge node, air-gapped operation
TCL — Translational Compression Layer	Semantic serialization and transcoding

Every layer is implemented in all four SDKs (Python reference; TypeScript, Go, and Rust are pure derivations) with byte-identical wire format.

Where OSMP Sits

Layer	What it does	Components
Application	Agent framework and LLM composition	MCP, A2A, ACP, CrewAI, AutoGen, LangGraph
Encoding	Instruction serialization (OSMP replaces JSON here)	SAL, SAIL, Composition Validator, ASD, BAEL
Transport	Byte delivery	HTTP, LoRa, BLE, WiFi, Meshtastic, satellite, serial, MQTT, TCP/UDP

OSMP is not a framework. It is an encoding layer. Two agents using different frameworks that share the OSMP grammar and dictionary can communicate with no modification to either framework.

Four AI-native namespaces (J/Q/Y/Z) encode what agents do internally, not just what they communicate. The J→Y→Z→Q chain encodes the full AI cognitive pipeline as a transmissible instruction sequence, decodable by ASD lookup without neural inference.

The v16 release (Q4 2026) makes 3-character primaries (e.g., AGT, HLT, ENV) the canonical form, with v15 single-letter forms preserved as deprecated siblings. See docs/adr/ADR-001-asd-generated-from-canonical-dictionary.md for the dictionary discipline.

What's Built Today

Click to expand the deliverables list

Instruction encoding across all 26 standard namespaces — 356 opcodes drawn from authoritative sources: IEC 61850 (energy), ICD-10/SNOMED CT/CPT (clinical), ISO 20022/FIX/SWIFT (financial), ISO 10218-1:2025 (robotics), FEMA ICS/NIMS (emergency management), BDI/PDDL/HTN (cognitive AI), OpenAI/Anthropic APIs (model operations). Registered macro architecture with 16 Meshtastic macros (pre-validated multi-opcode chain templates invoked via A:MACRO[name]).
Four AI-native namespaces — J (Cognitive Execution State), Q (Quality/Evaluation/Grounding), Y (Memory + Retrieval), Z (Model/Inference Operations). No prior agent communication protocol defines these.
Two-tier corpus compression — D:PACK applies OSMP encoding followed by lossless dictionary-based compression for at-rest storage. Two profiles: D:PACK/LZMA (full-corpus) and D:PACK/BLK (zstd block-level, microcontroller target with single-code random access in 38KB SRAM). D:UNPACK retrieves semantic content by ASD lookup against the SAL intermediate representation.
Three MDR domain corpora — CMS FY2026 ICD-10-CM (74,719 codes, 477KB), ISO 20022 eRepository (47,835 definitions, 1.2MB), MITRE ATT&CK Enterprise v18.1 (1,661 entries, 20KB). All three are D:PACK/BLK dict-free binaries resolvable across SDKs without network access.
Layer 2 accessors — Bracket-enclosed slot values from external open-ended registries: H:ICD[R00.1], H:SNOMED[concept_id], H:CPT[99213], K:ISO[MessageDefinitionIdentifier]. Layer 2 slot values are exempt from the single-character encoding rule.
R:ESTOP hard exception — executes immediately on receipt of any single fragment, regardless of loss tolerance policy, fragment completeness, or I:§ authorization state. Asymmetric harm: unnecessary stop is recoverable; failure to stop a physical agent in emergency is not.
Overflow Protocol — Tier 1 (single packet, ≤51 bytes at LoRa SF12), Tier 2 (sequential burst), Tier 3 (DAG decomposition for conditional branches and dependency chains). Three loss tolerance policies: Φ (Fail-Safe), Γ (Graceful Degradation, default), Λ (Atomic — required for K and H namespace instructions with irreversible consequences).
BAEL floor guarantee — the protocol never makes an instruction longer than its natural language input. When the encoded form exceeds the natural language form, BAEL selects NL_PASSTHROUGH and transmits the original with a flags bit. Compression is never negative.
SAL/SAIL isomorphic encoding — every SAL instruction compiles to a SAIL binary representation and every SAIL payload decompiles back to the identical SAL instruction. Bijective: no information lost in either direction.
FNP handshake and SALBridge — propagation by contact — Two-message capability advertisement + acknowledgment (40B + 38B = 78 bytes total). Negotiates dictionary alignment, namespace intersection, and channel capacity in two LoRa packets. When FNP detects a non-OSMP peer, the session transitions to FALLBACK. The SALBridge handles boundary translation; peers that learn SAL through contextual exposure transition to ACQUIRED.
ADP dictionary synchronization — The ASD Distribution Protocol keeps dictionaries aligned across nodes after initial FNP handshake. Delta-based updates with version pointers and tripartite resolution flags (additive, superseding replacement, deprecation).
Sovereign namespace extension — Ω: (U+03A9) allows any implementing party to define proprietary namespace extensions without central approval.

Roadmap

Current focus: full Rust SDK feature parity (decoder/encoder/bridge/FNP shipped at 0.1.0; MDR resolve, full benchmark harness, and Pangram handshake to follow).

Open contributions welcome:

C++ firmware-level encoder/decoder — sovereign OSMP nodes on ESP32 / nRF52 with the ASD compiled into flash. Today, OSMP integration with Meshtastic via the Python SDK and Meshtastic Python library is operational; the C++ contribution target eliminates the companion-device dependency.
Kotlin and Swift mobile SDKs — feature parity with the four shipped SDKs.
Additional MDR namespaces — SNOMED CT, RxNorm, LOINC are future namespace targets.

Contributing

See CONTRIBUTING.md. The spec is authoritative. All SDK implementations are validated against the canonical test vectors. A conformant implementation must achieve ≥60% mean UTF-8 byte reduction with zero decode errors.

Wanted: C++ firmware encoders, Kotlin/Swift mobile SDKs, and MDR corpora for additional regulated domains.
