Day-one Development

Internal product developers only

This page is for people who build Engineering Runtime (binary, hubs, docs, Control Plane). Customers and end users should use docs.engineeringruntime.com (Installation / Local Setup) instead.

Engineering Runtime is a multi-repo project. Day-one means: clone the map, bootstrap local siblings, read the owning hub’s CLAUDE.md, then edit with relative paths. Do not treat GitHub URLs as the day-to-day workflow.

Canonical project map (source of truth for layout): engineering-runtime-workspace/CLAUDE.md.


Who owns what

Surface Hub Typical work
Runtime binary, providers, engines, policy/audit Productengineering-runtime Go CLI / SSOT
Capabilities, samples, releases, AI agent, docs, series, this developer site Product children Supportive of the binary
Portal / app / shared API Control Plane Governance UI + api.engineeringruntime.com
ER map, bootstrap scripts, feature proposals Workspace Intake + day-one tooling
Raw thought-leadership drafts Blogs Drafts → polish into series

Dependency model (product): engineering-runtime is the SSOT. Other product children must not invent features the binary does not support. Extend the binary first, then update supportive siblings in the same effort.

Control Plane is a separate hub. Runtime must keep working if Control Plane is down. The only required product → Control Plane publish path is regenerating the UI catalog via app-api deploy-cloud-run (workflow_dispatch).


mkdir -p ER && cd ER
git clone https://github.com/kishore-gutta/engineering-runtime-workspace.git
cd engineering-runtime-workspace
./scripts/bootstrap.sh

bootstrap.sh clones missing hubs and children (never overwrites existing checkouts), then runs verify.sh. Fix any and re-run until you see Ready for development.

Scripts lifecycle

Script When What
bootstrap.sh Day one (safe to re-run) Clone missing hubs + children; then verify
update.sh Daily git pull --ff-only on every checkout (skips dirty trees); fill missing children; verify
verify.sh Anytime Clones + Go 1.23+ + Docker health
clean.sh Optional Remove local junk only — never deletes git repos

Daily:

cd engineering-runtime-workspace
./scripts/update.sh

2. Open the right folder in Claude Code / Cursor

Read in this order before large edits:

  1. engineering-runtime-workspace/CLAUDE.md — ER map
  2. Owning hub CLAUDE.md — product or Control Plane
  3. Target child CLAUDE.md — e.g. engineering-runtime/, app-api/

Practical tip: open the ER/ folder (or workspace + the hub you will edit) so relative sibling links resolve.


3. Hub-only clones (optional)

Use these when you do not need the full tree.

Product hub only

git clone https://github.com/kishore-gutta/engineering-runtime-product.git
cd engineering-runtime-product
./scripts/clone-children.sh

Hub guide: engineering-runtime-product/CLAUDE.md.

Control Plane hub only

Portal / app / API day-one does not require the product hub:

git clone https://github.com/kishore-gutta/engineering-runtime-control-plane.git
cd engineering-runtime-control-plane
./scripts/clone-children.sh

Hub guide: engineering-runtime-control-plane/CLAUDE.md.

Binary-only (minimal)

git clone https://github.com/kishore-gutta/engineering-runtime.git
cd engineering-runtime
go build -o runtime .
./runtime version

Also see that repo’s LOCAL_SETUP.md and docs/05-development/local-setup.md.


4. Build and smoke-test the binary

See Local Development for build commands and a throwaway Runtime Home sandbox.

Requirements: Go 1.23+ (verify script reports this).


5. Local siblings (day-to-day rule)

Inside a hub, read and edit peers with relative paths (../engineering-runtime-docs/, ../engineering-runtime-portal-ui/, …). After workspace bootstrap, sibling hubs under ER/ are local too.

GitHub / gh api is a rare fallback only when a peer checkout is missing — prefer ./scripts/update.sh to clone it.

Children stay separate git remotes. Commit and push in each repo you touch. Hooks may remind or edit local siblings; they must never git push another repo’s remote.


6. New features — propose, approve, implement, close

Do not land new product or Control Plane features from workspace intake until a proposal is approved.

Step Who Action
1. Capture anyone Drop notes/screenshots in engineering-runtime-workspace/inbox/ (local-only; not committed)
2. Propose author / agent Copy analyzed/proposals/_TEMPLATE.mdYYYY-MM-DD-short-slug.md. Set Status ready-for-review. Commit workspace. Stop.
3. Approve human reviewer Same file: Status approved or rejected, Reviewer + date. Commit workspace.
4. Implement developer / agent Re-read Status. Only if approved, edit the named Owner hub / Primary repos. Commit those repos.
5. Close developer / agent Status → implemented. Clear related inbox/ files. Commit workspace.

Status meanings:

Status May implement in product/CP?
draft / ready-for-review / rejected No
approved Yes — scope in that proposal only
implemented No — already done

Background notes (not a ticket queue): analyzed/reading/.

7. Same-effort updates (product hub)

When a change lands in the binary (or changes what it supports), update every relevant supportive sibling before you finish, for example:

Change Also update
New/changed provider or CLI engineering-runtime-docs (+ PROGRESS.md)
New reusable capability engineering-runtime-capabilities (+ sample if proving CI)
New term / architecture story engineering-runtime-series (must not invent beyond the binary)
Hub / day-one developer process engineering-runtime-developer (this site)
Release binary engineering-runtime-releases + docs release notes

Public sites:

developer.engineeringruntime.com This site — internal day-one / hubs
docs.engineeringruntime.com Customer how-to — must match implemented surface
