Why DiffLore

AI adoption is a team sport.
Most teams still play it solo.

The gap between your AI power users and everyone else is the biggest unclaimed productivity win in your org. DiffLore turns your champions' everyday sessions into a playbook the whole team learns from — without anyone writing a doc.

Every team has a champion

One or two engineers quietly get 3× out of Claude. What actually makes them fast is invisible to everyone else on the team.

The edge is the setup, not the prompt

Their real advantage is configuration — the MCP servers they wired in, the skills and subagents they lean on, the CLAUDE.md that keeps output on the rails. None of it shows up in a diff.

…and it vanishes at merge

The session behind a great PR disappears the moment it lands. Reviewers inherit the code, never the reasoning — or the setup — that produced it.

DiffLore makes the whole setup visible

Not just what was typed — how the session was actually run.

Prompt · alex

Add a token-bucket rate limiter to the ingest endpoint — 100 req/s per key, return 429 with a Retry-After header. Cover it with tests.

Thinking

Token bucket fits — refill 100/s, capacity 100. I'll key on the API key, keep state in Redis so it holds across instances…

Edit · ingest/limiter.ts

+ export function allow(key: string) {

+ const b = bucket(key)

+ return b.take(1)

· +48 −2

Bash · bun test

✓ limiter.test.ts 14 pass, 0 fail

Result

Added allow() with Redis-backed buckets, wired it into the ingest handler, and covered burst + refill in tests. ✅
