Why Harlay

Claude won’t hand your work to Cursor. Cursor won’t hand it to Codex. Harlay will.

They compete for your subscription, so none of them will ever build the way out. Harlay sits above all of them, on your machine, and turns every limit into a handoff.

Without Harlay1h 48m

Waiting for the 6:00 PM reset. Or twenty minutes pasting logs into another tool and explaining the task again.

With HarlaySeconds

Same task, open in the next tool, starting on the line where the last one stopped.

How it works

Four steps.
Zero copy-paste.

Harlay sits in your menu bar and does nothing until a session dies. Then it moves fast.

  1. 01

    Detect

    Catches exit codes, 429s and “usage limit reached” banners as they happen. Or hit ⌃⌥H to hand off yourself.

    exit 1 · HTTP 429 · banner text
  2. 02

    Extract

    Reads the conversation straight from local logs and app storage, then checks git to see what really changed.

    jsonl · sqlite · indexeddb · git diff
  3. 03

    Distill

    Drops cat dumps, retry loops and dead ends. Keeps the goal, the progress, the blocker and the next move.

    112k tokens → ~2k tokens
  4. 04

    Rehydrate

    Opens or focuses the target with files attached and the brief pre-filled. Nothing left to do but send it.

The brief

112k tokens of mess in.
One page out.

Every handoff produces the same four-part brief. Small enough to paste anywhere, specific enough that the next model starts on the right line.

98% smaller. Nothing the next agent needs is gone.

Goal

Move auth from session cookies to JWT across api/. Keep the existing tests green.

Done

  • Added src/lib/jwt.ts with sign and verify helpers
  • Swapped cookie middleware for JWT in auth.ts
  • Migrated 9 of 12 route handlers

Blocked on

tests/auth.spec.ts:48 expected 401, got 500. verify() throws on expired tokens instead of returning null.

Changed files

src/lib/jwt.ts            +41
api/middleware/auth.ts    +18  −27
api/routes/*.ts           +64  −88

Handoffs

You pick where
the work goes next.

Set a target and a fallback for each source. Turn on auto and Harlay hands off without asking.

Local by default

      
Your logs stay on your machine.
Only the brief moves.

    

    

      
Reads, never uploads
Session history and git state are parsed on device. There is no Harlay server in the middle.

      
You see it first
Review or edit the brief before it lands. Or skip that and run zero-click.

      
Your accounts, your keys
Targets open in apps you are already signed in to. Fallback agents use your own API keys.

    

  






  

    
Stop waiting
for the reset.
