sync-sdk-after-regen

---

name: sync-sdk-after-regen description: Use this skill in the space-gass-api repo whenever the OpenAPI spec or the regenerated Kiota SDK clients change — typically right after the generate-clients workflow lands a "regenerate SDK clients" commit on main, or any time descriptions/preview/openapi.json is updated. It brings the hand-written C# and Python examples, the Zudoku docs pages, and the dynamic code-snippet generator back in line with the new SDK surface. Trigger phrases: "regenerated SDKs", "spec updated", "fix examples after regen", "sync after kiota", "update for new build", or after a commit titled "regenerate SDK clients".

sync-sdk-after-regen

This skill replays the post-regen sync workflow that was hand-walked for build 14.50.65. It assumes you are at the repo root of space-gass-api and the latest spec + generated SDK clients are committed.

Goal: every example compiles, every doc page references current endpoints/models, the Zudoku docs site builds, and the snippet generator emits valid SDK code.

Phase 1 — Diff the spec and SDKs

Build the change matrix that drives every later edit:

1. Spec history — git log --oneline -- descriptions/preview/openapi.json then diff the latest two commits (or against origin/develop if working on a feature branch). Note: removed/added paths, renamed query parameters (esp. plural→string SG-list filters like case→cases), renamed path parameters ({key}→{id}), and any change to info.x-space-gass-build.
2. C# Generated diff — git diff <prev>..HEAD -- sdks/csharp/client/SpaceGassApi/Generated. Look at:
   • SpaceGassApiClient.cs for new/removed top-level builders
   • Models/ folder additions/removals (typical breaking change: XCreate renamed to XUserCreate, etc.)
   • Item/ folder renames
3. Python Generated diff — same under sdks/python/client/space_gass_api. Python mirrors C# but with snake_case file/property names.
4. Default port / base URL change — grep -rn "localhost:[0-9]\+" .. The desktop service port has changed historically (e.g. 5000 → 34560). If the spec's servers[0].url or any ServiceInfo model docstring shows a new host, sweep all hard-coded references in CLAUDE.md, sdks/*/client/.../Extensions/, every example header comment, and every doc page curl block.
5. Verify the regen committed cleanly — dotnet build sdks/csharp/examples/SpaceGassApi.Examples.sln against the SDK alone (no example edits yet). If it fails with CS0234: namespace 'X' does not exist, the regen committed an inconsistent tree (a builder references a folder that wasn't generated/committed). Fix by re-running kiota generate (see CLAUDE.md for the full command set, or .github/workflows/generate-clients.yml). Don't hand-edit Generated/.

Output of this phase: a written change matrix you can refer back to.

Phase 2 — C# examples

Files: every Example.*/Program.cs under sdks/csharp/examples/. Apply the change matrix, paying attention to:

• Response model field renames (most common: .Key → .Id on Node, Member, Section, Material, etc.).
• Request body type renames (e.g. SectionCreate → SectionUserCreate).
• Filter query parameters: collection endpoints now take string? properties named Cases, Members, Modes, Nodes in SG list format ("1,3-7,10") instead of int[] arrays. Compose with string.Join(",", ids) for arbitrary sets.
• Indexer parameter type: [int] typed indexer is preferred; the legacy [string] indexer is marked [Obsolete].

Verify: dotnet build sdks/csharp/examples/SpaceGassApi.Examples.sln --nologo. Build must be 0 errors before moving on.

Phase 3 — Python examples

Files: every entry-point .py under sdks/python/examples/*/. Mirror Phase 2 with snake_case:

• .key → .id on response models
• by_key(...) → by_id(...) on collection indexers (also by_run_id etc. for non-id path params — leave those alone)
• case_ (legacy attribute name) → case on NodeReaction/Buckling*/etc.
• keys=[...] → nodes="1,2,3" for reactions filters
• from space_gass_api.models.section_create import SectionCreate → from space_gass_api.models.section_user_create import SectionUserCreate
• Drop list arguments to case_/member/mode filter setattrs in favour of cases/members/modes with SG-list strings

Verify: python -m py_compile <each entry-point> (Python interpreter must be on PATH; if not, do a careful visual diff and rely on the C# build as a structural backstop). The two SDKs share the same shape, so anything that landed cleanly in C# almost always lands cleanly in Python.

Phase 4 — Docs MDX

Files: docs/pages/**/*.mdx. Use grep -rn "\.Key\|\.key\|by_key\|case_\|FileStatusRequest\|SectionCreate\|case=\d\|member=\d\|node=\d\|mode=\d\|QueryParameters\.\(Case\|Member\|Mode\|Node\)\b" docs/pages to find every stale reference, then patch:

• quick-start.mdx, simple-beam.mdx: .Key/.key → .Id/.id, by_key → by_id, case_ → case
• filtering-and-querying.mdx (the heaviest): rewrite filter examples to use the SG list-string format. C#: config.QueryParameters.Cases = "1,3"; Python: setattr(c.query_parameters, 'cases', '1,3'); curl: ?cases=1,3&nodes=10-12. Update prose ("Access any entity by its key" → "by its Id").
• file-handling.mdx: client.File.Status.PostAsync(new FileStatusRequest{...}) → client.File.Status.GetAsync(config => config.QueryParameters.FilePath = ...). The endpoint changed from POST-with-body to GET-with-query.
• error-handling.mdx: nodes.by_key(999) → nodes.by_id(999).
• versioning.mdx: confirm version table; mention the new info.x-space-gass-build value in passing if relevant.

Do NOT introduce hand-rolled curl URLs that expand request body fields as query string — only the endpoints whose spec changed (e.g. /file/status).

Verify: cd docs && npm ci && npm run build. The Zudoku build must succeed and produce docs/dist/docs/. If the Vite SSR .mjs patch fires (postinstall), that's expected — see docs/patches/fix-zudoku-mjs.js.

Phase 5 — Snippet generator audit

File: docs/zudoku.config.tsx, function generateCodeSnippet.

As of build 14.50.128 the generator reads the request-body type straight from the spec — it does NOT guess from the path, and there is NO BODY_TYPE_OVERRIDES map any more. The helper bodyTypeFromSpec(operation) reads the component name from the dereferenced body schema: Zudoku keeps the original pointer on schema.__$ref (and schema.items.__$ref for bulk/array bodies — see node_modules/zudoku/src/lib/oas/parser/dereference/index.ts), so the exact name (MovingLoadVehicleCreate, SectionUserCreate, …) is always recovered. The old per-regen chore of adding override entries is gone. The path-based {Entity}Create/Update/Item derivation survives only as a fallback for inline (un-$refd) bodies.

What to still check after a regen:

1. __$ref still resolves (Zudoku-upgrade guard). __$ref is an undocumented Zudoku internal. If a Zudoku version bump renames or drops it, every snippet silently falls back to the path guess and starts emitting wrong names. Two checks:
   • Mechanism: the dereferencer must still write it — grep -n '__\$ref' docs/node_modules/zudoku/src/lib/oas/parser/dereference/index.ts must show the assignment (current.__$ref = $ref; confirmed present at 0.82.2), and bodyTypeFromSpec in zudoku.config.tsx still reads schema.__$ref ?? schema.items.__$ref.
   • Schema names still reach the client: after npm run build, grep the built output. Important caveat (verified at zudoku 0.82.2): generated snippet text is never prerendered into dist/ — snippets render client-side only. These greps match the schema names embedded in each API page's route data and the served spec copy, so they catch schema renames/disappearances but can NOT catch a broken __$ref:

   cd docs
   for t in MovingLoadVehicleCreate SectionUserCreate MaterialUserCreate CombinationLoadCaseItem; do
     echo "$t -> $(grep -rl "$t" dist/docs | wc -l) file(s)"; done   # all should be >0
   

   (MaterialCreate was renamed MaterialUserCreate server-side between builds 14.50.128 and 14.50.134 — update this list when schemas rename.) If the mechanism check is in doubt (e.g. after a Zudoku upgrade), the only real verification is in a browser: npm run preview (serves at http://localhost:4000/docs), open an irregular write endpoint (e.g. Moving Load Vehicles → Create) and confirm the C#/Python snippet shows MovingLoadVehicleCreate, not the naive path guess VehicleCreate.
2. Builder chain & Python module path — the chain (client.Job.Loads…) and the Python import (from space_gass_api.models.<snake> import <Type>) are still derived mechanically. Spot-check one new endpoint's rendered C# and Python snippet.
3. Filter query params — unchanged: the generator does NOT emit query params; filtered-query snippets are a docs-page job, not a generator job.

Naming-consistency sanity check (spec-smell report)

Because the generator now trusts the spec, inconsistent schema naming no longer breaks snippets — but it is a real spec smell worth surfacing to the API team (e.g. a User qualifier on one sibling create endpoint but not its peer). Run this to list every write endpoint whose body schema name diverges from the {Entity}Create/Update/Item convention its path implies:

python - <<'PY'
import json
P=json.load(open('descriptions/preview/openapi.json'))['paths']
def pascal(s): return ''.join(w[:1].upper()+w[1:] for w in s.split('-'))
def sing(w): return w[:-3]+'y' if w.endswith('ies') else (w[:-1] if w.endswith('s') else w)
def body(op):
    try: s=op['requestBody']['content']['application/json']['schema']
    except Exception: return None
    return (s.get('$ref') or s.get('items',{}).get('$ref','')).split('/')[-1] or None
for path,ops in sorted(P.items()):
    for m,op in ops.items():
        if m not in ('post','patch','put'): continue
        actual=body(op)
        if not actual: continue
        seg=next((s for s in reversed(path.strip('/').split('/'))
                  if not s.startswith('{') and s not in ('bulk','items')),'')
        implied=f"{pascal(sing(seg))}{'Item' if path.rstrip('/').endswith('items') else ('Create' if m=='post' else 'Update')}"
        if actual!=implied:
            print(f"{m.upper():5} /{path.strip('/'):55} {actual}  (path implies {implied})")
PY

This is a report only — schema names are a server-side decision; this skill never renames them. Expect a large baseline (54 at builds 14.50.134 and 14.50.139, unchanged between the two): many flags are legitimately off-convention by design and are NOT problems — action bodies (OpenJobRequest, SaveJobRequest, MovingLoadGenerateRequest), shared settings types reused across run/settings endpoints (BucklingSettingsUpdate), and consistent domain prefixes (MovingLoad*). Don't try to "fix" those. The two signals that are actionable:

• Sibling disagreements — peer endpoints that should match but don't. The historical example (since resolved server-side): POST /job/structure/sections → SectionUserCreate but POST /job/structure/materials → MaterialCreate; by build 14.50.134 materials was renamed MaterialUserCreate to match its sibling. New disagreements of this shape read as accidental.
• Build-over-build deltas — run the script against the previous spec too and diff; a new divergence that doesn't fit an existing pattern usually means the backend's naming drifted in this build.

Put the grouped list (and any sibling disagreements / new deltas called out) in the Phase 6 report so the API team can decide whether to normalise.

Phase 6 — Report

Summarise per-track files touched, build status, and anything left unverifiable (e.g. "no Python interpreter available, py_compile skipped — relied on visual review and C# build as structural backstop"). Flag any new endpoints in the spec that have no example coverage. Include the naming-consistency report from Phase 5 (the spec-smell list) so the API team can see any new schema-naming inconsistencies this build introduced.

Out of scope for this skill

• Regenerating the SDK itself (that's the generate-clients workflow). If you must regenerate locally, follow the exact kiota generate flags from .github/workflows/generate-clients.yml to avoid drift, and commit Generated/ files separately from example/doc edits.
• Adding new examples or doc pages — this skill keeps existing material in sync, it doesn't expand coverage.
• A changelog page (deferred — revisit on a future regen).

Reference: known model/property migrations

Keep this short — the diff in Phase 1 is the source of truth. These are confirmed migrations seen at build 14.50.65:

Old	New
Node.Key / Member.Key / Section.Key / Material.Key	.Id
WithKeyRequestBuilder (path {key})	LoadCasesItemRequestBuilder etc. (path {id})
by_key(int)	by_id(int)
case/member/mode/node query params (array)	cases/members/modes/nodes (string, SG list format "1,3-7,10")
Python r.case_ (NodeReaction etc.)	r.case
SectionCreate	SectionUserCreate
MaterialCreate	MaterialUserCreate (between 14.50.128 and 14.50.134)
client.File.Status.PostAsync(new FileStatusRequest {...})	client.File.Status.GetAsync(config => config.QueryParameters.FilePath = ...)
