# Internal Tool Agents

Connect agents to tickets, repos, CI, Slack, and internal systems with scoped access and clear operating rules.

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

**Agents that work your tools, not just your code**

Engineering work lives in tickets, chat, and dashboards, not only repos. We connect agents to Slack, Linear, Jira, CI, and internal systems with scoped access, so routine coordination happens without a human relay.

## 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: Your systems, agent-operated.

- **Workflow integrations** Agents wired into tickets, repos, CI, and chat through MCP and native APIs.
- **Scoped permissions** Least-privilege access per tool, so agents do their job and nothing else.
- **Ticket-to-PR automation** Well-defined issues picked up, implemented, validated, and returned as PRs.
- **Status and reporting agents** Standups, release summaries, and stakeholder updates drafted from live system data.
- **Clear operating rules** What agents may do autonomously versus propose, written down and enforced.
- **Full audit trail** Every agent action logged and attributable.

## 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.

**Which tools can agents connect to?**

Anything with an API: Slack, Linear, Jira, GitHub, GitLab, CI systems, and internal services - typically through MCP servers we build or configure.
**How is access kept safe?**

Each agent gets its own identity with least-privilege scopes, explicit rules on autonomous versus proposed actions, and a complete audit log.
**What tasks fit this best?**

High-volume, well-defined work: triage, status reporting, small well-scoped tickets, and handoffs between systems. Ambiguous work stays with people.
**Do agents act autonomously?**

Within boundaries you set. A common pattern: autonomous reads and drafts, human approval on writes that affect others.
**How do teams adopt this without distrust?**

Start with agents that draft rather than act, show the audit trail, and expand autonomy as the accuracy record builds.
**Where does it all run?**

Your infrastructure or ours. Regulated teams run the full stack - agents, MCP servers, logs - inside their own boundary.
