Implementation
made easier for AI agents

Stop manually digging through Slack and Jira. Lem's agent automatically synthesizes institutional knowledge into actionable implementation files, right where you code.

Global Installation

Initialize the Lem ecosystem on your machine. Our lightweight CLI handles all background synchronization without slowing down your environment.

npm install -g lem

Workspace Provisioning

Securely link your local dev environment to your organization's knowledge graph using your personal access token.

# Objective: Resolve JWT Regression

The current middleware fails to trigger a refresh on tokens with < 5 minutes TTL. This was discussed by @Sara in Slack as a high-priority fix.

The LEM Protocol

Your proactive codebase enforcer.

Lem doesn't just observe — it intercepts, documents, and enforces engineering standards in real time.

PROTOCOL01

The Dependency Guard

When package.json changes, Lem intercepts the PR and asks for the architectural "Why". No more mystery libraries.

[INFO] PR #247 detected: +1 new dependency

[LEM] lem: "Why was lodash added? Document rationale."

[ OK] Dev response linked → Decision captured ✓

PROTOCOL02

The Decision Link

Lem matches Jira task IDs to branch names. It automatically attaches the relevant Slack thread to the code for future reference.

[INFO] Branch: feat/AUTH-221-sso-flow

[INFO] Linked: Jira AUTH-221 → Slack #dev-auth (3 threads)

[ OK] Context graph updated ✓

PROTOCOL03

The Silent Witness

Lem joins your Google Meet calls. It identifies technical decisions in real-time and updates the project wiki automatically.

[INFO] Meeting: Weekly Architecture Review

[LEM] Decision detected: "Migrate auth to OIDC"

[ OK] Wiki updated → ADR-0058 created ✓

Use Case

The Senior-to-Junior Bridge

Stop waiting hours for tribal knowledge. LEM delivers it instantly.

THE PROBLEM
JD

Hey, why did we use a custom debounce here instead of lodash?

Waiting for response...

4 hours later — Senior dev is in meetings all day

Junior dev context-switches to another task. Momentum lost.

THE LEM SOLUTION
JD

Why did we use a custom debounce here?

L

Sarah and Mike decided this in the Oct 12 Architecture Meeting to handle high-frequency IoT pings. Lodash's debounce didn't support the cancellation pattern needed.

NH

Why did we choose Postgres over DynamoDB in 2023?

L

Based on the architecture review meeting on March 15, 2023 and Slack thread #backend-infra, the team chose Postgres for its JSONB support and existing team expertise.
