This causes serde deserialization errors like `invalid type: string "100", expected u32`. Add discriminated-union resolution to the coercion layer: for oneOf/anyOf, match the active variant by const or single-element enum discriminators; for allOf, merge all variants' properties. Also propagate combinator awareness to schema validators, WASM wrapper helpers, and tool discovery so they no longer reject or ignore valid combinator-based schemas. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * test: add e2e tests for oneOf discriminated union parameter coercion Add three end-to-end tests using a fixture tool that mirrors the github WASM tool's oneOf schema with #[serde(tag = "action")] deserialization. Each test sends string-typed numeric/boolean params through the full agent loop, verifying that coercion resolves them before serde runs: - list_issues: limit "100" → 100 (integer in oneOf variant) - get_issue: issue_number "42" → 42 (integer in different variant) - create_pull_request: draft "true" → true (boolean in variant) Without the coercion fix these fail with: invalid type: string "100", expected u32 Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * test: add real WASM github tool e2e tests with HTTP interception Load the actual compiled github WASM binary, send params with string-typed numbers through the coercion layer, and verify the WASM tool constructs correct HTTP API calls via a new HTTP interceptor in the WASM wrapper. Changes: - Add `http_interceptor` field to `StoreData` and `WasmToolWrapper` so WASM tool HTTP requests can be captured/mocked in tests - Make `prepare_tool_params` and `coercion` module public for integration tests - Add 3 e2e tests loading the real github WASM binary: - list_issues: `limit: "50"` → URL contains `per_page=50` - get_issue: `issue_number: "42"` → URL contains `/issues/42` - list_pull_requests: `limit: "25"` → URL contains `per_page=25` Tests gracefully skip if the WASM binary isn't compiled. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * refactor: simplify WASM e2e tests to use TestRig with with_wasm_tool() Replace the manual WasmToolWrapper construction with TestRig integration: - Add `with_wasm_tool(name, wasm_path, capabilities_path)` to TestRigBuilder that loads real WASM binaries and wires the shared HTTP interceptor - Build the HTTP interceptor before tool registration so it can be shared between AgentDeps and WASM tool wrappers - Rewrite github WASM e2e tests to use the standard trace pattern: TraceLlm sends tool calls with string params, http_exchanges specify expected outgoing requests and canned responses The test code is now identical to other trace-based e2e tests — no custom interceptors or manual WASM construction needed. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: address review comments on combinator schema support - Validate `has_combinators` checks array type (`.as_array().is_some()`) instead of bare `.is_some()` to reject malformed `{ "oneOf": {} }` - Validate top-level `required` keys against merged combinator variant properties when no top-level `properties` exists (both validators) - Deduplicate oneOf/anyOf handling into single loop in coercion.rs - Revert `pub mod coercion` to private; only re-export `prepare_tool_params` - Call `after_response` on interceptor after real HTTP when `before_request` returns None (recording mode correctness) - Fix formatting (CI failure) Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: address second round of review comments - Fix headers deserialization bug: deserialize resp.headers_json as HashMap<String, String> then convert to Vec, not directly as Vec - Sort interceptor headers for deterministic trace fixtures - Update after_response comment: RecordingHttpInterceptor does exercise this path (returns None from before_request) - Mark WASM tests #[ignore] instead of silent skip — avoids false-green CI while keeping them runnable with --ignored - Fix with_wasm_tool signature: Option<PathBuf> instead of Option<impl Into<PathBuf>> which doesn't compile in nested position - Fix with_wasm_tool doc comment to match actual behavior - Revert prepare_tool_params to pub(crate) — no longer needed publicly Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: coerce empty strings to null for optional tool parameters LLMs often send "" instead of null/omitting optional parameters, causing parse errors in tools that expect typed values (e.g., timezone, schedule). PR #1127 fixed this per-field in the time tool. This commit adds dispatcher-level coercion so all tools benefit: - Non-required properties with value "" are coerced to null at the object level (based on the schema's `required` array) - Explicitly nullable schemas (`type: ["string", "null"]`) coerce "" to null in the per-value coercion path - Required string-only fields keep "" unchanged Closes #755 Co-Authored-By: spiritj <[email protected]> Co-Authored-By: Xing Ji <[email protected]> Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * feat: complete coercion coverage for $ref, nested combinators, and additionalProperties Close remaining coercion gaps so 3rd-party tools (MCP servers, complex WASM tools) work correctly: - $ref resolution: inline all #/definitions/<name> and #/$defs/<name> references in a pre-pass before coercion, with depth limit (16) for circular ref safety - Nested combinators: resolve_effective_properties now recurses into variants that themselves contain allOf/oneOf/anyOf (depth limit 4) - additionalProperties inheritance: check allOf variants and matched oneOf/anyOf variant for additionalProperties schemas New tests: - resolves_ref_and_coerces_referenced_properties - resolves_nested_refs_in_oneof_variants - coerces_nested_combinators_allof_containing_oneof - coerces_array_items_with_oneof_discriminator - circular_ref_does_not_infinite_loop Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: address third round of review comments - Validators: tighten has_combinators to require at least one object-typed variant (has type:"object" or properties), rejecting non-object combinator schemas like { "oneOf": [{"type":"integer"}] } - Empty-string coercion: only coerce "" → null when schema allows null or doesn't allow string; pure type:"string" fields keep "" as meaningful - Fix comment: "coerce to null" → "return unchanged" for empty strings with no type match (code returns None, not null) - Redact credentials before passing to after_response interceptor to prevent secret leakage into recorded trace files - Switch to tokio::fs::read for async WASM binary loading in test rig - Add doc comment explaining soft URL check in WASM e2e tests Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * ci: retrigger after staging merge [skip-regression-check] * fix: merge staging, report non-array combinator values as errors Merge latest staging to fix CI (missing fallback_deliverable field). Add explicit error reporting when oneOf/anyOf/allOf values are not arrays in both strict and lenient validators. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: recurse into combinator variants that have properties but no explicit type Both validators only recursed into variants with `type: "object"`, missing variants that define `properties` without an explicit type (common in allOf patterns). Now recurse when variant has either.
