# Maintenance Agents

Agents that handle cleanup, dependency updates, deprecated APIs, and repo hygiene before they block delivery.

_[Agentic Delivery](/agentic-delivery) › [Custom Agents](/capabilities/custom-agents)_

**The chores your backlog never gets to, done**

Small maintenance debt compounds into blocked upgrades and slow onboarding. We deploy agents that handle cleanup, deprecations, and repo hygiene continuously, so debt is paid weekly instead of accruing interest.

## Custom Agents

- 3x Delivery acceleration · 80% Effort executed by agents
- Industry runs on our tooling · 50M+ OSS downloads / month
- 3.7× Lower task cost vs Opus 5.5
- Built on Agent Device. · T3 · Shopify · Tester Army · Agent Device
- React Foundation Founding Member · 300+ commits to React Native · Contributing since 2016
- 100+ Enterprise projects delivered
- ISO 27001 certified

## What you get: A codebase that stays clean.

- **Dependency updates** Routine bumps opened, tested, and ready for one-click merge.
- **Deprecated API cleanup** Old patterns migrated before they become upgrade blockers.
- **Dead code removal** Unused modules, flags, and assets identified and safely removed.
- **Lint and type debt** Warnings and suppressions burned down toward a clean baseline.
- **Repo hygiene** Docs, configs, and CI definitions kept consistent across repositories.
- **Verified changes only** Every maintenance PR validated by tests and QA runs before it asks for review.

## Scope → Build → Scale: Build agents into repeatable workflows.

### Scope (1 WEEK)
We select a product workflow, define where agents act, and agree the controls and success measures.
- Workflow and owners defined
- Baseline and controls agreed
- Token budgets confirmed
### Build (1-12 MONTHS)
We connect context, agents, and verification to your tools, then run the workflow on your product backlog.
- Running on your product backlog
- Speed and quality measured
- Business impact validated
### Scale (AS NEEDED)
We document the workflow, transfer ownership, and extend it across teams and products based on results.
- Your team owns the workflow
- Expand based on results
- Full knowledge handover

## Let’s find the right path for your product.

**How safe are automated maintenance changes?**

Every change ships as a PR with tests and real-device validation attached. Nothing merges itself unless you explicitly allow it for low-risk categories.
**How is this different from Dependabot or Renovate?**

Those open version bumps. These agents also execute the migration the bump requires, fix the fallout, and verify behavior - the part that actually costs your team time.
**What is automatable and what is not?**

Mechanical, verifiable work automates well: bumps, deprecations, dead code, config drift. Architectural refactors stay with engineers, with agents doing the legwork.
**Will this flood us with PRs?**

No. Batching rules, priorities, and a weekly budget keep the flow steady and reviewable.
**Does it work in a monorepo?**

Yes. Scoped runs per package, coordinated changes across packages when needed, and hygiene rules enforced repo-wide.
**What do we see over time?**

Debt metrics trending down: outdated dependencies, deprecation count, warning volume, and the upgrade lag that used to block releases.
