How Long Does It Take to Build an AI Agent? Real Timeline
DevPilot's own Linear bridge code shows the real time sink: webhook wiring and dispatch logic, not the agent's reasoning.

How DevPilot is built, and why. Mostly the decisions that were harder than they looked.
Dispatch vs Adoption: How DevPilot Sends Issues to Agents
DevPilot's dispatch_queue assigns issues to agents. See what's proven live, what's stubbed, and how adoption differs from dispatch.

What Does an Agent Orchestrator Do? Inside DevPilot's Graph
An agent orchestrator owns sequencing, retries, and pauses for review — not execution. See the real split from DevPilot's codebase, code table included.

Why adding agents stops making things faster
The critical path is the longest dependency chain in a plan. Nothing you do to the rest of the graph moves the finish line until you shorten it.

Six numbers that tell you if a plan is any good
A plan can be valid and still bad. Parallelization, peak width, wave efficiency, dependency density and file conflict are computable before dispatch.

How many coding agents should you run at once
Two limits, not one. A global cap protects your machine and your bill; a per-plan cap protects the work from itself. Confusing them is the common mistake.

Writing specs that agents can actually follow
A plan an agent can execute has checkable properties: acyclic dependencies, exclusive file ownership, and tasks that fit in a single context.

Waves, not queues, for parallel agent work
A queue keeps agents busy. A wave keeps them coherent. The difference is a barrier, and it is why auto-advance is a real feature rather than a scheduler.

A column called encrypted, with no cipher behind it
An audit found api_key_encrypted was plaintext. Fixing the cipher was the easy half — the hard half was proving nothing else can read the column.

Guards that throw, because a forgotten if fails open
Our entire bridge API was unauthenticated once. The fix was not more care — it was making the authorization check impossible to skip by accident.

Claiming work exactly once, with one UPDATE
Two machines race the same queue row. No advisory lock, no SELECT FOR UPDATE — the conditional UPDATE is the acknowledgement, and the loser gets nothing.

The delivery guarantee is a table, not a websocket
We moved dispatch off Pub/Sub and onto a Postgres row. The transaction boundary is the whole reason, and Realtime became an optimisation.
