fix(sdk): honor MCP mutation fields and type authoring builders - #1541
Conversation
Route MCP create and update through canonical SDK mutation option contracts instead of the partial flat-field allowlist. Preserve explicit nested aliases, repeatable inputs, custom workspace metadata and false booleanish values. Reject malformed containers, discarded scalar values, invalid repeatable entries and non-boolean force values before durable writes. Keep native SDK mutation admission and advisory unknown-field compatibility intact. Put create completion fields in the canonical option table and recognize valid workspace fields through the public SDK field lookup. Verify advertised schemas against persisted items, imported timestamps and immutable history; compare item/history bytes after refused mutations. Use const generic parameters and exact keys across object authoring builders. Retain contextual callback types and zero-cost identity, expose supported flag metadata, and validate public packed declarations with TypeScript 5.9.3 and Node/Bun consumers plus a deliberately degraded declaration control. Include generated SDK/contracts, documentation, package-owned changelog and structured PM closure evidence for pm-gh1538, pm-gh1539 and pm-ap7ilf. Record the new MCP executable-help report under its own open, unclaimed canonical item. Validation: 10,982 tests passed with three skips; exact coverage is 100/100/100/100. Full static, terminal defect evidence, linked tests, packed npm/npx/Bun/bunx smoke and generated changelog checks pass.

#1538,src/sdk/runtime-input.tsaccepts advertised top-level mutation fields, gives nested aliases precedence, validates inputs before writes, and reports refusal instead of a successful no-op. The integration tests verify persisted flat updates, precedence, and unchanged item and history data after invalid input. For#1539,src/sdk/define.tsuses const generics andExactDefinitionconstraints. The public-entrypoint type tests verify literal preservation, contextual callbacks, and rejection of unknown keys.

Reviewer's GuideThis PR aligns MCP create/update execution with canonical SDK mutation contracts to ensure advertised fields persist correctly and invalid inputs fail atomically, while strengthening SDK authoring builders with exact-key validation and literal/contextual typing; public contracts, documentation, generated artifacts, tests, and tracker records are updated accordingly.

Codecov Report✅ All modified and coverable lines are covered by tests. 📢 Thoughts on this report? Let us know! |
A mixed tags array could become a CSV string before mutation preflight checked its types. A request containing tags=[valid,4] and a sibling title therefore persisted both fields instead of refusing the malformed value. Check merged create/update CSV-array inputs before conversion, preserving explicit nested alias precedence and legacy read normalization. Keep valid string and empty arrays, including a valid nested replacement for an invalid flat value. Reject non-string entries before any item or history write. Extend the public request-to-persistence regressions for flat and nested create and update failures, byte-identical refusal snapshots, empty arrays and nested replacement. Update conformance docs and include the structured closure and package-generated changelog for pm-gllxud in the existing grouped delivery. Validation: both new regressions fail before the guard and pass afterward. All nine linked tests and the full 10,982-test suite pass; exact coverage is 100/100/100/100 with no uncovered counts. The public stdio control preserves the original item after refusal. Local static retries refuse registry transport failure; mandatory hosted static, security and coverage checks remain required before merge.

Boolean readers could discard malformed values such as clearComments=42 while a sibling title was persisted. Validate all canonical action boolean parameters and registered aliases against the SDK schemas before normalization, including force and top-level receipt controls. Keep legitimate true/false values, polymorphic regression metadata and project fields with names used by other actions, rather than applying unrelated global parameter types to custom data. Extend the public create/update regressions with atomic malformed-flag refusals, real true/false effects, aliases, receipt controls and a custom offline field. Record structured closure evidence for pm-7qg4jz and regenerate the changelog through the latest pm-changelog package. Retain release/performance observations in their canonical records and queue release receipt diagnostics separately. Validation: the pre-fix controls fail and the corrected public stdio probe refuses without changing the item. All linked tests and packed npm/npx/Bun/bunx smoke pass. The complete static command passes after registry feed recovery, and joint registry/OSV evidence covers all 568 locked versions with no findings. All 10,982 tests pass with three skips; exact coverage is 100/100/100/100 over 70,263 statements, 54,026 branches, 14,479 functions and 66,578 lines. Terminal defect evidence and the package-generated changelog check pass.

Document lookup order across the configured option target, camelized field key, CLI flag and aliases. State own-property and defined-value semantics, including preservation of explicit false/null and the undefined fallback. No runtime behavior or public signatures change. Reuse pm-ap7ilf for the final review correction, retaining earlier closure history and recording the new source/documentation link and sandboxed test run. Build, 33 focused integration/contract tests, docstring/export checks, the public-surface snapshot and documentation links pass. Regenerate the changelog through the latest pm-changelog package. Retain the repeated CodSpeed report and the independently dispatched, immutable-main control under pm-bj7rq0. Release that broader investigation open without changing benchmark fixtures, performance budgets or provider acknowledgements; final-head hosted admission remains required.

Advertised MCP create/update fields could return success without persisting values, and malformed values could disappear while sibling changes were written. Both actions now use canonical SDK mutation contracts, preserve nested alias precedence and custom project fields, and refuse lossy inputs before item or history writes. Array elements are checked before CSV conversion, and declared boolean fields are checked through action schemas and aliases before coercion. Create also retains imported completion metadata and explicit false values.
SDK object builders now preserve literal names/actions and contextual callback types while rejecting unknown top-level keys. Supported repeatable and value-validation flag metadata is available directly to package authors. Public declarations, generated contracts, docs, and the package-generated changelog are updated together. The runtime-field helper export documents lookup precedence and explicit false/null preservation.
The requested delivery scope also includes GitHub issue intake and independent security, dependency and release checkpoints. Those PM records retain evidence and canonical owners; the executable-help report stays queued and unclaimed.
Validation:
pm-changeloggeneration/check.All three actionable review threads are resolved and their fixes confirmed inline. Additional full-review coverage remains unavailable under free quota and trial limits.
Tracking: pm-gh1538, pm-gh1539, pm-ap7ilf, pm-gllxud, and pm-7qg4jz. All tracker changes were made through the CLI. New intake remains open and unclaimed: executable help in pm-gh1540, and original release-feed receipt retention in pm-z20n3s.
Closes #1538
Closes #1539
