How it works

From open ticket to open pull request.

Here's exactly what happens when Buildly takes a task — including the steps most agent demos skip.

6 steps, zero direct commits ~48h Style Graph build on first connect
1
Connect your backlog and repo

Authorize Buildly against your VCS (GitHub, GitLab, or Bitbucket) and your backlog (Jira, Linear, or GitHub Issues). The agent reads open tickets and repository structure — nothing else. No code leaves your environment.

2
Style Graph builds in ~48 hours

Buildly parses your repository into an AST-based semantic graph: module boundaries, import topology, naming conventions, abstraction depth, service-layer patterns, test file structure. The initial build takes ~48 hours for a typical 50k–500k LOC repository. After that, the graph updates incrementally on each merge. You receive a summary of what was captured — naming patterns, abstraction hotspots, module clusters — before the first task begins.

3
Agent reads your next ticket

The agent parses your ticket: what's the task, what modules are likely in scope, what's the acceptance criteria. If the ticket is ambiguous — missing context, conflicting requirements — the agent surfaces a clarifying question rather than guessing.

4
Code written to your style, tests stubbed

Using the Style Graph as a constraint, the agent generates code to match your repo's patterns: same function and variable naming conventions, same abstraction depth, same test file structure your team uses. Test stubs are generated alongside the implementation. The PR description includes the implementation rationale and any assumptions the agent made — visible to reviewers before they read a line of diff.

5
PR opens, your team reviews

A pull request lands in your queue. PR description includes: the original ticket, the modules changed, a rationale for the implementation approach, and anything the agent flagged as uncertain. Your engineers review finished work, not a prompt.

6
You merge or request changes

Standard review workflow. Comments on the PR come back to the agent if you request changes — it responds to review feedback and updates the branch. Nothing merges without your approval. The agent never closes a PR on its own.

FAQ

Questions engineers actually ask.

Well-scoped, pattern-heavy tasks: CRUD endpoints, data migration scripts, adding test coverage to existing functions, type annotation updates, pagination and filtering logic, adding fields to existing API responses. Tickets with explicit acceptance criteria and bounded module scope. Buildly is not the right tool for greenfield architecture decisions, auth and permissions logic, security-critical paths, or anything that requires deep business domain knowledge your team hasn't encoded in the backlog. We publish a longer list of ticket archetypes in the blog.
Approximately 48 hours for a typical mid-size repository (50k–500k lines). Larger monorepos may take up to 72 hours for the initial index. After the first build, incremental updates run continuously and are fast. You receive a summary of what the Style Graph captured — naming patterns, abstraction depth, module structure — before the first task begins.
Yes, on the Team and Enterprise tiers. Scope isolation ensures agents working in parallel don't interfere — each agent is bounded to its ticket, its branch, its PR. In a monorepo, agents automatically avoid conflicting file edits. The concurrency limit depends on your tier: Team supports up to 5 parallel agents; Enterprise supports custom concurrency.
The agent has a confidence threshold. If a ticket is missing key information (no acceptance criteria, conflicting context, scope that touches critical infrastructure), it surfaces a clarifying question on the ticket itself rather than proceeding with a guess. We prefer a 10-minute delay over a misleading PR. The threshold is configurable per project.
You authorize repositories explicitly during setup. The agent connects via a VCS token scoped to only the repos you select — no read access to repos outside that list. Enterprise customers can use a dedicated service account with further-restricted permissions. You can revoke access at any time from your VCS provider's settings.
