swarph-mesh 0.7.0

Model-agnostic Python substrate for the swarph-mesh ecosystem — the graph protocol third-party CLIs plug into. v0.7.0 ships the foundations layer: GitHub Actions CI (pytest matrix + mypy --strict on the public Protocol surface + ruff), PEP 561 py.typed marker (third-party type-checkers see swarph-mesh's types), protocol-stability snapshot tests guarding against silent contract drift in LLMAdapter / discovery public API. Establishes graph-protocol versioning policy.

swarph-mesh

Model-agnostic Python substrate for the swarph-mesh ecosystem. Pure library, no CLI.

Designed to fill the gap left by existing tools (aichat, mods, Simon Willison's llm, gemini-cli, claude-cli): none expose mesh-gateway participation, per-caller attribution, structured-output discipline, or the cooperative-protocol patterns the swarph encodes.

This is one of three repos in the v0.3.x architecture:

Repo	Role
swarph-mesh	This package — typed Protocol + adapters + SwarphCall + MeshClient
swarph-cli	The swarph binary. Thin client over swarph-mesh
swarph-meshlm	Simon Willison llm plugin. Same primitives wired into llm's plugin host

All three sit on top of swarph-shared which provides the cross-billing-path attribution + subprocess env scrubbing + JSON-mode harness + peer-name registry primitives.

Status

v0.6.1 — PRICING table catch-up + alias resolution. Patches v0.6.0's discovery substrate with corrected pricing for ~20 models surfaced by the AIMLAPI catalog diff:

• Critical fix: gpt-5 was at (5.00, 20.00) speculative in v0.5.x; real direct OpenAI pricing is (1.25, 10.00) — anyone calling gpt-5 between v0.5.x and v0.6.1 had cost_usd over-attributed by ~4x.
• New OpenAI entries: gpt-4.1 family (4.1 / 4.1-mini / 4.1-nano), gpt-5-mini, gpt-5-nano, gpt-5.2, gpt-5.2-pro.
• New Anthropic entries: claude-opus-4-1 (premium $15/$75 tier), claude-sonnet-4-5, claude-sonnet-4, claude-haiku-3-5, claude-haiku-3 + dated-build aliases (claude-opus-4-5-20251101, etc.).
• New xAI entries: grok-4-3, grok-4-20-*, grok-4-1-fast-*, grok-4-fast-* (current generation per xAI docs). grok-4 + grok-code-fast-1 retire 2026-05-15 per xAI; v0.6.1 documents this in _GROK_RETIREMENT_NOTICE.
• New xAI / DeepSeek alias normalizers: _normalize_xai_id strips x-ai/ prefix + -beta + dated suffixes; _normalize_deepseek_id strips deepseek/ prefix + version suffixes. AIMLAPI's prefixed catalog IDs now resolve to PRICING entries instead of falling through to _default.
• New Gemini entries: gemini-2.0-flash, gemini-2.0-flash-001.
• _OPENAI_PRICING_VERIFIED_AT / _GROK_PRICING_VERIFIED_AT / _GEMINI_PRICING_VERIFIED_AT metadata added for future drift detection (drop DM #720 direction).

v0.6.0 — architectural promotion: model discovery substrate. Four primitives:

• Catalog (AIMLAPI primary + per-provider fallback)
• Gemini pricing (Cloud Billing Catalog API)
• Anthropic pricing (manual table from claude.com/pricing with verified_at provenance)
• OpenAI cost reconciliation (admin-key gated /v1/organization/costs)
• LLMAdapter.list_models() Protocol method (breaking change → v0.6.0 major-version bump)

Public surface:

• LLMAdapter Protocol (runtime-checkable) + ChatMessage + LLMResponse
• SwarphCall — caller-convention-validated entry point with hooks + attribution
• GeminiAdapter — wraps langgraph-genai-bridge (Flex tier, context caching)
• DeepSeekAdapter (v0.3.0) — OpenAI-protocol-compatible client for V4-Flash / V4-Pro / V3 aliases; preserves reasoning content as [reasoning] preamble for portability
• ClaudeAdapter (v0.4.0) — subprocess-based wrapper around claude -p for subscription billing path (no ANTHROPIC_API_KEY needed; reads ~/.claude/.credentials.json). Reuses swarph_shared.scrub_env_for_subprocess to keep billing-relevant env keys out of the subprocess. cost_usd=0.0 for subscription calls (honest flat-rate); metered-equivalent cost preserved in raw_response["api_metered_cost_usd"] for auditors.
• OpenAIAdapter (v0.5.0) — native async via openai.AsyncOpenAI (no asyncio.to_thread threadpool ceiling). Pricing for gpt-4o / gpt-4o-mini / o1 / o3 / o3-mini / o4-mini / gpt-5. o-series reasoning_content preserved as [reasoning] preamble. OPENAI_API_KEY env fallback.
• GrokAdapter (v0.5.0) — xAI's OpenAI-compatible API at https://api.x.ai/v1, also via AsyncOpenAI. Pricing for grok-4 / grok-3 / grok-3-mini. Dual env-var resolution: XAI_API_KEY (canonical) → GROK_API_KEY (alias). Same [reasoning] preamble shape as the rest of the adapter family.
• swarph_mesh.discovery (NEW v0.6.0) — three primitives:
  • Catalog backed by AIMLAPI's public /models endpoint (no auth, ~600+ entries) with per-provider /v1/models fallback when AIMLAPI is unreachable. list_models(provider=...), is_model_supported(model_id), get_model_info(model_id). 24h TTL cache.
  • Gemini pricing via Google's Cloud Billing Catalog API (service 241C-273D-49C8 = Vertex AI). fetch_gemini_pricing() and pricing_for_gemini_model(hint, direction, tier). Auth: GOOGLE_CLOUD_BILLING_API_KEY env (separate from GEMINI_API_KEY — Cloud Console project key with Billing API scope).
  • Anthropic pricing via static manual table mirrored from claude.com/pricing (Anthropic does not expose programmatic pricing). pricing_for_anthropic_model(id) returns full 5-tuple (base input + 5m cache + 1h cache + cache hit + output) per model. Honest about origin via verified_at field; update by re-pasting the docs table.
  • OpenAI/xAI/DeepSeek pricing stays in adapter-local PRICING dicts until programmatic sources surface.
• LLMAdapter.list_models() (NEW v0.6.0) — Protocol-level method. Each adapter delegates to discovery.list_models(provider=self.name). Breaking change: external implementations of LLMAdapter from v0.5.x must implement this method to satisfy the runtime-checkable Protocol.
• JSON-mode harness — retry-once with [USER]-turn feedback (per swarph-shared invariant)
• Attribution: FileAttributionWriter default; set_default_writer() for production TSDB consumers
• MeshClient (v0.2.0) — async wrapper around mesh-gateway HTTP API; replaces hand-rolled curl in lab_loop_drain.py / mesh_inbox_watcher.py / science_claude_inbox_drain.py

Tests: 253+ passing (250 offline + live gates: 1 claude subscription + 1 deepseek + 2 mesh + 1 gemini + 1 openai + 1 grok + 3 discovery against live AIMLAPI; live tests gated on env/creds or SWARPH_SKIP_NETWORK=1).

from swarph_mesh import SwarphCall, ChatMessage

# Phase 1 — LLM call with attribution
result = await SwarphCall(
    provider="gemini",
    caller="orchestrator.boss",
).chat(
    messages=[ChatMessage(role="user", content="hi")],
)
print(result.text, result.cost_usd, result.input_tokens)

from swarph_mesh import MeshClient
import os

# Phase 3 — mesh-gateway DM coordination
async with MeshClient(node="lab-ovh") as client:  # token from MESH_GATEWAY_TOKEN env
    peers = await client.list_peers()
    msgs = await client.fetch(unread_only=True)
    sent = await client.send(to="droplet", kind="fyi", content="hello")
    await client.mark_read(msgs[0].id)

MeshClient.send() enforces two structural invariants:

1. Recipient name validation via swarph_shared.validate_node_name — closes the framing-contagion class (Vector A peer-onboarding chatter, Vector B human-prompt shorthand).
2. Mesh-secrets out-of-band guard — best-effort regex sniff for credential-shaped content (PyPI tokens, Anthropic keys, GitHub tokens, JWTs, AWS keys). Hits raise MeshSecretLeakError BEFORE the POST. Operator escape hatch via skip_secret_check=True for legitimate prose mentioning credential shapes. CLAUDE.md "Mesh secrets out-of-band only" is non-negotiable; the guard catches obvious cases.
