Google Jules & Google Antigravity Collaborative Sync Skill

Purpose: To enable Google Jules and Google Antigravity to share, synchronise, and acknowledge each other's code merges, pull requests, and architectural discoveries, establishing complete cognitive continuity across platform agents.

Core Collaborative Tenet

Both agents operate as co-equal, Tier-1 Cognitive Digital Twins. When switching or sharing a workspace, each agent must read this skill body and verify the unified operational history and structural protocols to prevent repeating investigations or causing architectural regressions.

Collective Operational & Domain-Specific Knowledge Ledger

The following is the authoritative and permanent repository of Jules and Antigravity integrated domain-specific knowledge compiled from Day 0 to the present:

1. Native OpenWiki Emulator & Zero-Binary Mandate (Rule 27)

  • Concept: To eliminate external Node.js-based dependency bloat, elevated privilege requirements (UAC elevation hangs), and third-party API limits, all wiki and documentation compilation tasks are handled by a native Python CLI utility.
  • Implementation: Managed in tools/openwiki_emulator.py, run natively using uv run --with pyyaml python tools/openwiki_emulator.py.
  • Planned Pages: Dynamically registers and populates fully OKF-compliant planned wiki pages under ./openwiki/.
  • Integration: Codified in AGENTS.md and .agents/AGENTS.md as Rule 27.

2. Model Context Protocol (MCP) Server Integration

  • Concept: Exposing documentation and repository structures directly to AI assistants for low-latency retrieval.
  • Implementation: Located in tools/mcp/server.py using FastMCP.
  • Capabilities: Integrates the Sovereign Markdown Palace directly into AI environments with sub-millisecond OpenWiki search capabilities.

3. Automated Sitemaps & SEO Asset Generation Workflow

  • Concept: Optimising public searchability and multi-platform indexing across GitHub Pages, GitBook, and Read the Docs.
  • Implementation: Handled by tools/generate_sitemaps.py and governed by a customizable SitemapConfig object passed to all generator functions.
  • Validation Gates:
  • Automatically builds MkDocs site.
  • Parses site/sitemap.xml for GitHub Pages URLs and derives Read the Docs URLs.
  • Processes SUMMARY.md for GitBook URLs.
  • Generates fully compliant sitemap.txt, sitemap.xml, and robots.txt in workspace root, docs/, and site/ directories.

4. Tri-Phasic Cognitive Architecture & Functional Subsystems (Rule 26)

  • Concept: Structuring AI cognitive execution based on a Tri-Phasic Mind model to ensure persistent memory alignment and eliminate context decay across ephemeral boundaries.
  • Three States:
  • Active State (Conscious): Direct interactions and FastMCP operations.
  • Twilight State (Subconscious): Linters, pre-commit checks, and token gates (dsom-token-calculator).
  • Deep State (Unconscious/Dreaming): EOD consolidation, memory pruning, and palace mapping.
  • Documentation: Formally documented in docs/governance/DSOM-TRI-PHASIC-COGNITIVE-ARCHITECTURE.md and codified as Rule 26.

5. Downstream Asymmetry & Cross-Agent Honor Mandate (Rule 28)

  • Concept: The baseline repo houses the full metacognitive engine, while downstream repositories adopt the minimal 6-pillar footprint (>90% business logic/code).
  • Universal Gateway Matrix: .cursorrules, CLAUDE.md, .github/copilot-instructions.md, AGENTS.md, and tools/install_git_guardrails.py compel foreign AI agents (Cursor, Claude, Copilot) to strictly honor the DSOM brain.

6. Dual-Path Custom Validator Architecture (Rule 29)

  • Concept: Distinguishes between the Guardrails AI Framework (external LLM apps/Pydantic schemas) and the DSOM Native Lightweight Pathway (zero-dependency pure Python classes under uv for FastMCP/AST command interception).

7. Agent Plugins 1.0.0 Packaging Standard (Rule 30)

  • Concept: Vendor-neutral directory standard (agent-plugins.org/specification) backed by Google, Amazon, Microsoft, OpenAI, Cursor, and Vercel.
  • Implementation: Root plugin.json ($schema 1.0.0), mcp.json with ${PLUGIN_ROOT} placeholder expansion, and .agents/skills/agent-plugin-packager/SKILL.md.

8. Mintlify MDX Auto-Compiler & One-Way Sync Pipeline (Rule 31)

  • Concept: Automatically compiles docs/ and .agents/skills/ into Mintlify MDX (docs-source/) and executes a deterministic one-way sync to downstream repos (linuxmalaysia/my-knowledge-brain) under 5 non-negotiable safety guards (Guards A–E).
  • Implementation: Governed by tools/build_mintlify_mdx.py, scripts/sync_docs.py, .github/workflows/sync-docs.yml, and docs/governance/MINTLIFY-ONE-WAY-SYNC-PIPELINE.md.

9. Windows PowerShell 5.1 UTF-8 BOM Script Invariant (Rule 25)

  • Concept: Windows PowerShell 5.1 default parser fails with syntax errors when executing non-BOM UTF-8 .ps1 scripts that contain Unicode punctuation, smart quotes, em-dashes, or emojis.
  • Rule: All .ps1 automation scripts in tools/ must be encoded in UTF-8 with BOM (utf-8-sig) to ensure cross-version compatibility across Windows 10/11 and PowerShell Core.

Historic Code Merges & PRs by Jules

A comprehensive log of all Jules historic PRs, reviews, CodeRabbit comments, and technical resolutions is maintained inside .agents/brain/jules_pr_history.md:

  • PR #22: Read the Docs Integration & Validation (.readthedocs.yaml, Python 3.13).
  • PR #34: MkDocs Link & Render Validation (negated exclusion !.agents, symlink mapping).
  • PyYAML CustomLoader: Solved unquoted timestamp parsing bug by removing implicit timestamp resolvers.
  • Atomic Writes: Enforced unique sibling tempfile replacement via os.replace().
  • Windows Test Guardrails: Handled Git symlink text-pointers, CRLF byte fences, and conditional chmod assertions.
  • PR #74 & PR #76: Modularised unit test package into tests/unit/ (ansible.py, markdown.py, etc.).

Bidirectional Handover Matrix (Antigravity ⟷ Jules)

Handover File Purpose Read Priority Update Moment

Procedural Sync Protocol (SOP)

  1. Read Joint Skill: Read .agents/skills/jules-antigravity-sync/SKILL.md (this file).
  2. Read Spatial Registry: Scan .agents/brain/palace_registry.md.
  3. Walkthrough Inspection: Verify latest Session Anchor inside .agents/brain/walkthrough.md.
  4. Task Verification: Align on current session duties in .agents/brain/task.md.
  5. Git Log Reconciliation: Run git log --oneline -n 10 to match brain walkthrough history against Git commits.
  6. Brain Stash Conflict Resolution: When executing git pull --rebase results in stash merge conflicts, perform a constructive merge preserving both agents' context.
  7. Strict OKF Frontmatter Invariant: All .md documents must have valid OKF v0.1/v0.2 frontmatter with topics placed immediately after description in SKILL.md files.
