Connect the repo
YCall reads the codebase, recent changes, failing jobs, and the task thread before touching code.
Private beta for developers who cannot afford context switching
Your on-call AI engineer.
YCall investigates urgent codebase tasks, writes focused fixes, runs validation, and hands you a clean PR while you keep building.
ycall run #2471
Current task
Investigate why OAuth refresh fails after the latest session middleware refactor. Patch and prove the fix.
1Investigate
Read failing job, recent commits, and auth middleware
2Patch
Narrow session refresh guard and update regression test
3Validate
npm test auth/session-refresh.spec.ts -- --runInBand
4PR ready
Diff is 42 lines, risk notes attached, reviewer requested
Validation trace
PASS$ npm test auth/session-refresh.spec.ts
✓ refresh token survives middleware redirect
✓ expired cookie path returns reauth state
✓ no regression in GitHub provider callback
diff --git app/auth/session.ts
- refreshOnRedirect: false
+ refreshOnRedirect: isTrustedReturn(url)
Pull request draft
Fixes refresh handling in authenticated redirects. Includes regression coverage and a note on untested SAML providers.
Why now
AI made shipping faster. It also made codebases easier to overload.
More diffs
Engineers now produce more code, tests, and dependency churn per week.
More interruptions
Small urgent fixes steal deep work from the person best positioned to move product.
More validation debt
The hard part is no longer typing code. It is proving the change is safe.
Workflow
Page YCall when a task needs investigation, code, and proof.
It behaves like a careful teammate: reads context, shows its work, validates changes, and keeps the final merge under your control.
02
Assign the interruption
Send the bug, flaky test, upgrade, or cleanup request while you stay in your current task.
03
Watch the run
It investigates, patches, explains tradeoffs, and exposes logs instead of hiding behind magic.
04
Review a validated PR
You get a focused diff, test evidence, and a merge-ready summary with human approval preserved.
Use cases
Delegate the work that is too important to ignore and too disruptive to own right now.
Failing CI triage
Production bug reports
Dependency upgrades
PR cleanup
Refactor follow-through
Test coverage gaps
Trust model
Built for real repositories, review culture, and production caution.
Sandboxed execution
Runs in isolated task environments with explicit repo access boundaries.
Test-first validation
Every proposed fix ships with commands run, outputs captured, and gaps named.
Human merge gate
YCall can draft and validate, but developers keep approval over the final code path.
Private beta
Bring YCall into your next urgent engineering interruption.
Early access is focused on developers with active repos, frequent CI failures, or recurring maintenance work that keeps breaking flow.
