Legend * `[x]` = Completed * `[ ]` = Pending * `[P]` = Parallelizable (can run with other \[P] tasks) * `[SNNMM]` = Session reference (NN=phase number, MM=session number) * `TNNN` = Task ID *** ## Progress Summary | Category | Total | Done | Remaining | | -------------- | ------ | ------ | --------- | | Setup | 3 | 3 | 0 | | Foundation | 6 | 6 | 0 | | Implementation | 9 | 9 | 0 | | Testing | 4 | 4 | 0 | | **Total** | **22** | **22** | **0** | *** ## Setup (3 tasks) Initial configuration and environment preparation. * [x] T001 \[S2201] Verify Phase 21 prerequisites, current detection behavior, and v2.3 Antigravity reference paths (`.spec_system/PRD/phase_22/session_01_antigravity_detection_data_contract.md`) * [x] T002 \[S2201] Inspect current Antigravity fallback shape in example and e2e fixture data (`src/data/live-data.example.json`) * [x] T003 \[S2201] Confirm focused test command targets for script detection and live-data validation (`package.json`) *** ## Foundation (6 tasks) Core structures and base implementations. * [x] T004 \[S2201] Extend script-side `AppDetection` with Antigravity `surfaces` and `usage` fields as an additive contract (`scripts/lib/app-detection.ts`) * [x] T005 \[S2201] Define client-side Antigravity surface and usage types matching the script contract with exhaustive optional-field handling (`src/lib/live-data-types.ts`) * [x] T006 \[S2201] Add Antigravity validator defaults for absent surfaces and usage with schema-validated input and explicit error mapping (`src/lib/validate-live-data.ts`) * [x] T007 \[S2201] \[P] Add app-detection test fixtures for Antigravity IDE, CLI, conversation entries, unreadable stats, and sanitization (`scripts/lib/__tests__/app-detection.test.ts`) * [x] T008 \[S2201] \[P] Add live-data validator fixture cases for valid, absent, and malformed Antigravity payloads (`src/lib/__tests__/validate-live-data.test.ts`) * [x] T009 \[S2201] \[P] Create focused Antigravity live-data contract tests for nested surface and usage normalization (`src/lib/__tests__/antigravity-live-data.test.ts`) *** ## Implementation (9 tasks) Main feature implementation. * [x] T010 \[S2201] Implement independent Antigravity IDE detection via existing macOS app helpers with sanitized browser output (`scripts/lib/app-detection.ts`) * [x] T011 \[S2201] Implement independent Antigravity CLI detection via `resolveCliPath` and common local paths with timeout, fallback, and failure-path handling (`scripts/lib/app-detection.ts`) * [x] T012 \[S2201] Implement Antigravity conversation directory scanning for bounded `.pb` and `.json` file counts with cleanup on scope exit for all acquired resources (`scripts/lib/app-detection.ts`) * [x] T013 \[S2201] Implement last-active metadata from file mtimes without exposing raw filenames or absolute conversation paths (`scripts/lib/app-detection.ts`) * [x] T014 \[S2201] Implement bounded `usage.savedEquivalent` emission for Antigravity usage with finite-number guards and absent-state fallback (`scripts/lib/app-detection.ts`) * [x] T015 \[S2201] Wire the composed Antigravity object so top-level `detected`, compatibility `path`, `surfaces`, and `usage` degrade safely when inputs are missing (`scripts/lib/app-detection.ts`) * [x] T016 \[S2201] Update live-data validation to normalize Antigravity nested objects, reject unsafe strings, and preserve additive defaults (`src/lib/validate-live-data.ts`) * [x] T017 \[S2201] Update committed fallback example data with safe Antigravity surfaces and usage shape (`src/data/live-data.example.json`) * [x] T018 \[S2201] Update browser-test live-data fixtures with the same safe Antigravity shape and no private local paths (`tests/e2e/fixtures/live-data.ts`) *** ## Testing (4 tasks) Verification and quality assurance. * [x] T019 \[S2201] Run focused script detection tests and fix regressions (`scripts/lib/__tests__/app-detection.test.ts`) * [x] T020 \[S2201] Run focused live-data validation tests and fix regressions (`src/lib/__tests__/validate-live-data.test.ts`) * [x] T021 \[S2201] Run script/app type checks to verify the additive contract compiles (`tsconfig.scripts.json`) * [x] T022 \[S2201] Validate ASCII encoding, privacy boundaries, and session artifacts before handoff (`.spec_system/specs/phase22-session01-antigravity-detection-data-contract/spec.md`) *** ## Completion Checklist Before marking session complete: * [x] All tasks marked `[x]` * [x] All tests passing * [x] All files ASCII-encoded * [x] implementation-notes.md updated * [x] Ready for the validate workflow step *** ## Next Steps Run the implement workflow step to begin AI-led implementation. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase22-session01-antigravity-detection-data-contract/tasks.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
