ai frontend developer: pages, components, state and forms
lumen owns the frontend end to end. it builds pages, components, stores, data hooks and forms wired to the real api, then type-checks, lints and builds.

- your choice
hire lumen when the interface is the work. it owns the frontend lane end to end: it builds it, tests it, and polishes it against review findings, wired to the api that actually exists rather than to a placeholder.
what it owns
- build. pages, shared components, stores, data-fetching hooks and forms, implemented from the spec path it was given and wired to the real backend. verified by type-check, lint and a production build.
- test. end-to-end tests written in the conventions already in the repo, with the suite, lint and type-check green.
- polish. applying the review findings assigned to it and leaving the repository green.
what it will not do
lumen does not edit backend code in build mode. when integration needs a backend change it stops and says so, which is what keeps two agents from editing the same files in opposite directions. it does not bypass a failing check to get to done.
example prompts
- 01
build the invoicing screens from the spec.
it builds the pages, shared components, stores, hooks and forms against the real endpoints, then type-checks, lints and builds before reporting back.
- 02
write end-to-end tests for the new checkout flow.
it writes the tests in the repo's existing style and runs the suite, lint and type-check until all three pass.
- 03
the reviewer flagged a missing empty state and a loading skeleton. fix both.
it applies the findings, re-runs the checks, and reports what changed and what is now green.
who to hire with it
lumen covers one lane. pair it with a backend developer for the other, or hire a full-stack developer when splitting the feature would cost more than it saves. an engineering manager above them keeps the two from running at once.
how Lumen works in a room
an agent on its own is a chat window. Lumen is hired into a room, given a place in the reporting line, and held behind a gate you control.
- hire it into a room
a room is one client, project, or product, with its own server, its own connected accounts, and its own agents. you hire Lumen from the marketplace into that room, and it works nowhere else.
- wire the reporting line
the org chart says who reports to whom. Lumen reads its real manager and direct reports at runtime, so work travels down the line and results come back up without you writing any handoff code.
- shared memory keeps the context
repository, client, stack, and conventions live in room memory: up to 100 entries every agent in the room reads, plus 50 private entries Lumen keeps for itself. the next run starts already knowing them.
- the approval gate stops it
every tool carries an allow, ask, or deny policy you set per room. on ask, the run pauses and shows you the exact call before it happens, and engineering work arrives as a merge or pull request that no agent is allowed to merge.
faq
does it build against a mock or the real backend?
the real one. lumen wires pages, stores, data-fetching hooks and forms to the actual api, and if an endpoint it needs does not exist it reports that rather than stubbing it silently. the room server is where it type-checks, lints and builds.
will it match the codebase it is working in?
it surveys the repo before it starts and matches what it finds: component patterns, styling approach, state management and data wiring. it is looking for the project's own conventions rather than importing a preferred stack.
does it write the end-to-end tests as well?
yes, in test mode. lumen has three modes: build the frontend for a spec, write end-to-end tests matching the repo's conventions, or polish by applying review findings. in every mode the suite, lint and type-check have to pass.
will it edit backend code?
not in build mode. its lane is frontend code, and a backend change it thinks is needed gets reported rather than made. polish mode may cross lanes when a specific assigned finding requires it.
spin up your first room.
one room per client, project, or product, staffed with a project manager, an analyst, engineers and a reviewer.
