services add compute --image/--port (create-with-image CLI)

[jwfing]

What & why

CLI side of compute create-with-image. insta services add compute <name> gains:

• --image <url> — run this container image at creation (compute only)
• --port <n> — port the image listens on (compute only; server defaults to 8080)

Both are rejected client-side for non-compute types (mirrors the existing --public storage-only check). insta services list now shows the running image for compute services (running <image>[:<port>]).

Pairs with insta-platform PR #54 (server accepts image/port on POST /services and returns them on Service). This CLI is a thin client, so the change is self-contained and unit-tested without a live platform.

Implementation

• servicesAdd (src/commands/services.ts): compute-only validation for --image/--port; request body extracted into a pure servicesAddRequestBody(...) helper (mirroring the existing deployRequestBody/billingLines convention) that includes image/port only when provided.
• servicesList: line rendering extracted into serviceListLine(...), which shows the image for compute rows.
• src/index.ts: --image/--port options on the services add command.

Testing

npm run typecheck + npm run build clean; npm test 105 tests pass (services.test.ts 12→27, covering: body includes image/port when passed, omits them when absent, rejects --image/--port on non-compute, and the compute list-line render). services add --help shows both flags.

Follow-ups (not in this PR)

• --port isn't format-validated (--port abc would send port:null); the in-file parseCount helper is the pattern to reuse — recommended small follow-up.
• The add success-message string isn't extracted for a unit test (the request body and validation are).

Summary by cubic

Adds create-with-image support to the CLI. insta services add compute <name> now accepts --image and --port, and insta services list shows the running image (with port).

• New Features

  • --image <url> and --port <n> on insta services add compute <name>; sent as image and numeric port to the API (server default port is 8080).
  • Client-side validation: --image/--port are compute-only; mirrors existing --public storage-only check.
  • services list shows compute images as running <image>[:<port>].

• Refactors

  • Extracted servicesAddRequestBody(...) to build the POST body and serviceListLine(...) for list rendering; both are pure and unit-tested.

Summary

Clean, well-scoped, thoroughly-tested thin-client change: adds compute-only --image/--port to insta services add and surfaces the running image in insta services list, following the repo's existing pure-helper + validation conventions. No blocking issues.

Requirements context

No matching spec/plan found — this repo has no docs/superpowers/ or docs/specs/ directory (top level is src/, test/, AGENTS.md, etc.). Assessed against the PR description, the paired insta-platform PR #54 contract described in the body, and in-repo conventions (AGENTS.md, src/commands/deploy.ts). Verified locally: npm run typecheck clean and npm test → 105 passing, matching the PR's stated results.

Findings

Critical

(none)

Suggestion

• Functionality — no numeric validation on --port (src/commands/services.ts:56). servicesAddRequestBody does ...(opts.port ? { port: Number(opts.port) } : {}). A non-numeric value like --port abc makes Number('abc') → NaN, which JSON-serializes to port: null and is sent silently (a user typo becomes a no-op rather than an error). --port 0 is likewise passed through as an invalid 0. This is a pre-existing pattern (deployRequestBody in src/commands/deploy.ts:16 has the same behavior), and the PR body already flags it as a follow-up, so it's non-blocking — but the in-file parseCount helper (services.ts:20) is the ready-made pattern to reuse for a fail-fast error. Non-blocking, low blast radius.

• Functionality — --port accepted without --image (src/commands/services.ts:63-64). Validation checks only that the type is compute; insta services add compute api --port 3000 (no image) is accepted and sends a bare port. If the platform ignores/rejects a port with no image this is harmless, but rejecting it client-side (or documenting that --port implies --image) would give a clearer error. Minor; server behavior via PR #54 governs the real outcome.

Information

• Convention — agent-facing flag doc lives outside this repo. AGENTS.md non-negotiable #4 requires command/flag changes to be mirrored in skills/insta/cli-reference.md in the insta-cloud superproject's skills/ submodule. That file isn't in this repo so it can't be part of this PR, but the two new flags should be reflected there as a follow-up so the agent-facing surface doc stays in sync.

• Software engineering — test coverage is strong. New tests exercise body inclusion/omission of image/port, the port-as-number coercion, validation throwing before any network/config access (nice, matches the helper's comment), and all serviceListLine render branches (image+port, image-only, no image, storage, postgres). This is the kind of coverage that would have caught a close-call regression in the list rendering.

• Security — no concerns. The image URL and port are user input but flow only into a JSON body via api.rawRequest (no SQL/shell/string interpolation), no secrets/PII are newly logged or returned, and no auth/authorization paths change.

• Performance — no concerns. serviceListLine is O(1) per row (same cost as the inlined code it replaces); no new queries, loops, or allocations.

Verdict

approved (informational — a human still gives the explicit GitHub approval). Zero Critical findings; the Suggestions are non-blocking and largely already acknowledged as follow-ups in the PR description.
