Resumen

Descripción del creador (original en inglés)

Bitemporal memory for AI agents with point-in-time recall and tamper-evident audit history.

Los tres pilares de PopNx MCP

Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.

Lians Guard

The current-state and completion guard for AI coding agents.

Lians recovers interrupted agent work, rejects stale task state, and blocks done until the current task is ready for human review.

Your agent can forget the chat. It cannot forget what is finished, what

changed, or what still has to pass.

  • Recover. Resume a bounded current task across supported Claude Code and Codex sessions.
  • Reject stale state. Bind checkpoints to current repository and task state so old evidence is not silently reused.
  • Guard completion. Separate measured evidence from an agent's own claims and keep the gate closed while work is missing, unknown, failed, or blocked.
  • Require review. READY FOR HUMAN REVIEW is a handoff to a person, never a claim that the work is correct, approved, or safe to deploy.
  • Stay local. The free recovery path needs no Lians account, AI password, or provider API key.

Lians works with your existing AI account and editor. It does not replace your model, Git, CI, repository instructions, or human review.

Two layers, one agent loop

The open-source Lians Guard layer lives inside Codex through MCP, skills, hooks, and repository state. It remembers corrections and exposes evidence without taking over the model. The optional Lians Mission Control beta is the local control layer: give it one mission, let it choose a bounded Codex route, and require a real verifier before it returns PASS.

On supported Codex versions, one Mission Control mission now uses one Codex app-server thread instead of starting a new process and replaying a summary for every stage. Codex still owns authentication, tools, sandboxes, and execution; Lians owns the durable mission, usage policy, and receipt. App-server is currently experimental, so the one-shot adapter remains available.

Inspect the Mission Control source, read the bridge boundary, or follow the external proof-gate protocol.

One clear result after every agent session

RECOVERED

Task: Fix OAuth callback handling Next: Re-run the callback integration test

STALE Reason: The authentication requirement changed after this checkpoint

BLOCKED Missing: OAuth callback integration test Untrusted: "tests passed" was reported by the agent, not measured

READY FOR HUMAN REVIEW Measured locally: callback tests passed Measured by CI: required checks passed

The trust model is deliberately strict. measured_local, measured_ci, and human_confirmed evidence can satisfy a criterion. agent_attested and inferred_activity records remain useful context but cannot open the review gate. An agent cannot promote its own checkpoint into a trusted class. Trusted CI evidence requires an exact GitHub attestation and commit match plus an interactive check-to-criterion mapping; human evidence requires interactive confirmation.

Try it in two minutes

Choose the AI tool you already use:

ToolFastest setup
Codex app, CLI, or IDEOne command
Claude CodeTwo plugin commands
CursorOne-click MCP install
Other MCP clientsMinimal MCP setup

For example, after installing uv, connect Codex with:

codex mcp add lians --env LIANS_MCP_ENABLED_TOOLS=remember,recall,list_memories,correct_memory,forget_memory -- uvx --from "lians-sdk[mcp]" lians-mcp

Restart Codex, then save one safe project fact and recover it in a fresh chat. Local memory is stored in ~/.lians/mcp.db by default. This is the available free recovery path; the full Guard workflow is currently a developer preview.

Follow the complete quickstart for setup, recovery, correction, deletion, and the Guard preview boundary.

What a fresh coding agent receives

Lians can generate a bounded project handoff instead of replaying a transcript:

Reported complete; verify:
  • migrated the orders API to /v2/orders

Still open:

  • verify the migration against current Git state
  • update documentation

Decisions:

  • keep pytest

Changed:

  • /v1/orders is stale; use /v2/orders

Next:

  • update documentation before touching unrelated UI

The handoff is derived from current Lians state, not a manually maintained summary. Agent-reported work remains visible without being mislabeled as verified completion.

Why this is not another generic memory layer

Native memories are convenient when work stays inside one product. General memory is no longer a scarce category. Lians uses local memory for recovery, then focuses on the expensive gap: current task state and evidence-backed readiness.

The current competitive landscape pressure tests this position against native Claude Code, Codex, Cursor, GitHub Copilot, Entire, Factory, and AI review workflows.

ApproachBest fitBoundary
Native tool memoryOne AI tool, minimal setupUsually stays inside that vendor
AGENTS.md or CLAUDE.mdStable repository instructionsMust be maintained manually
Transcript replayReconstructing one conversationLarge, noisy, and may revive stale decisions
Free Lians recoveryResume current project context across supported toolsRequires a local connection to each tool
Lians GuardDetect stale state and gate readiness with typed evidenceTeam workflow is still in developer preview

Lians is not claiming that every project needs a separate memory layer. See the honest comparison and decision guide.

Project status

Lians is under active development. Available recovery features and preview Guard features are separated here so the repository does not imply a production guarantee that does not exist yet.

Current evidence

The included Claude-to-Codex continuity fixture recovered 10/10 expected facts, exposed 0 stale facts as current, and produced a 231-token handoff. These are bounded beta results, not a promise that every live coding session extracts perfectly. Run the experiment.

The developing ContinuityBench v0.1 publishes the proposed cross-agent, freshness, correction, erasure, provenance, and boundedness test contract. Its current Lians fixture is evidence for that fixture only; it is not presented as a completed competitor leaderboard.

A separate live test saved a synthetic project fact through Cursor, recalled it in a new Cursor chat and a fresh Claude Code session, and confirmed it was gone after deletion. Read the test method.

The Guard correctness benchmark exercises missing evidence, unknown criteria, failed constraints, blockers, stale updates, and drift signals. It is a local, deterministic test of the configured policy, not proof of semantic correctness or a production outcome. Run packages/lians-easy/benchmarks/task_contract_correctness.py to inspect the cases.

Build with Lians

Use the local Python SDK inside an application:

pip install "lians-sdk[local]"
from datetime import datetime, timezone

from lians import LocalLiansClient

memory = LocalLiansClient(db_path=".lians/memory.db") memory.add( agent_id="my-agent", content="The project uses Python 3.12 and pytest.", event_time=datetime.now(timezone.utc), )

result = memory.recall( agent_id="my-agent", query="Which Python version and test runner should I use?", )

See the install guide for TypeScript, Go, Java, C, framework integrations, and self-hosting.

Running a class, club, hackathon, or campus developer group? Use the student and community kit. Contributors and package integrators can start with Supported paths and repository status.

Advanced capabilities

Lians also includes tools for project-scoped agent handoffs, signed selection and review receipts, local research and browser briefs, temporal reconstruction, lineage, information barriers, confirmed erasure, and bounded formal checks. These capabilities are useful for advanced or governed deployments but are not required for the starter memory workflow.

  • Memory engine
  • Cross-agent continuity experiment
  • Agent-work verification
  • Security model
  • Community and managed product boundary
  • Supported paths and repository status
