Bot Implementation Summary

Overview

Successfully implemented a complete bot system for the Zotero Plugin Registry that automates:

  • Plugin metadata validation
  • Remote update.json fetching and parsing
  • Version merging (remote + patched versions)
  • Compatibility detection
  • Output file generation (meta.generated.json, latest.json)
  • GitHub integration for CI/CD

Implementation Completed

1. Type System & Shared Package ✅

shared/src/types.ts

  • Extended PluginMeta with updateUrl (new), update_json (deprecated), and patchedVersions fields
  • Added GeneratedMeta for output with stats and compatibility info
  • Added LatestVersionInfo for quick-access version indexing
  • Added ProcessResult and PluginError types for error tracking
  • Regenerated meta.schema.json via pnpm run -C shared generate-schema

2. Data Loaders ✅

bot/src/loaders/meta.ts

  • Validates meta.json schema and required fields (id, updateUrl/update_json)

  • Checks ID matches directory name

  • Validates tags against predefined enum

  • Throws descriptive errors for validation failures

bot/src/loaders/update-json.ts

  • Fetches remote update.json from provided URL
  • Parses Zotero manifest format: addons[pluginId].updates
  • Extracts version, update_link, update_hash fields
  • Handles version compatibility: Zotero 7+ (zotero) and Zotero 6 (gecko)
  • Returns strongly-typed Version array

3. HTTP & XPI Utilities ✅

bot/src/utils/http.ts

  • Axios-based HTTP client with automatic GitHub authentication

  • Detects GitHub domains and applies Bearer token from GITHUB_TOKEN env var

  • 10-second timeout for all requests

  • Supports multiple response types (json, arraybuffer)

bot/src/utils/xpi.ts

  • downloadXpi(): Stream downloads with optional progress callback (30-second timeout)
  • extractXpiInfo(): Parses manifest.json from XPI (ZIP) files
  • verifyXpi(): Validates XPI structure and ID matching

bot/src/utils/git.ts

  • detectChangedPlugins(): Uses simple-git to find modified plugin directories in PR diffs

4. Version Merging & Compatibility ✅

bot/src/merger.ts

  • mergeVersions(): Combines remote + patched versions with intelligent override

    • Remote versions added first

    • Patched versions override on conflict (allows manual fixes)

    • Sorted by semantic version (desc) with fallback to string comparison

  • extractCompatibility(): Determines min/max Zotero versions
    • Handles both semver (Zotero 7+) and non-semver (Firefox legacy) versions
    • Graceful fallback to string comparison for non-semver entries

5. Core Processor ✅

bot/src/processor.ts

  • 7-step pipeline:

    1. Load & validate meta.json

    2. Fetch remote update.json

    3. Merge versions with patched versions

    4. Extract compatibility constraints

    5. Generate meta.generated.json (full metadata + versions + compatibility)

    6. Generate latest.json (quick-access latest version only)

    7. Update .cache.json with timestamp

  • Detailed consola logging at each step
  • Graceful error handling with stage identification
  • Processes multiple plugins with individual error tracking

6. CLI & Commands ✅

bot/src/cli.ts

  • Commander-based CLI with help text
  • Commands:
    • zbot build [plugins...]: Default, build all or specific plugins
    • zbot check [plugins...]: PR validation mode
  • Options:
    • --all: Build all plugins (explicit flag)
    • --help: Display help
    • --version: Display version

bot/src/build.ts

  • buildPlugins(): Orchestrates full build process

    • Auto-discovers all plugins if none specified
    • Processes with error collection
    • Exits with code 1 on failure

  • checkPlugins(): PR validation mode (TODO: git change detection)

7. GitHub Integration ✅

bot/src/github-reporter.ts

  • commentOnPR(): Posts validation errors as PR comments via Octokit

  • reportToIssue(): Creates/updates GitHub issue with error summary

  • Respects GITHUB_TOKEN, GITHUB_REPOSITORY, GITHUB_EVENT_NAME env vars

  • Graceful fallback if GitHub integration unavailable

bot/src/report.ts

  • Unified reporting to console and GitHub

  • Routes output basd on CI environment:

    • Local: console only
    • CI + PR: console + PR comment
    • CI + Scheduled: console + GitHub issue

Test Results

✅ Successfully processed test plugin: [email protected]

  • Loaded 2 remote versions from GitHub
  • Merged versions correctly
  • Detected compatibility: Zotero 6.999-8.*
  • Generated both output files

Generated Files

  • meta.generated.json: Full metadata + 2 versions + compatibility
  • latest.json: Latest version (1.26.0) for quick lookup
  • .cache.json: Processing timestamp for incremental updates

Code Quality

✅ All linting passed (ESLint with @antfu/eslint-config) ✅ No TypeScript errors ✅ Proper import ordering (builtin → external → type → local) ✅ No unused imports or variables ✅ ESM module system with .js file extensions

Dependencies Added

  • semver: Version comparison (7.7.3)
  • simple-git: Git operations (3.30.0)
  • consola: Pretty console output (already present)
  • axios: HTTP client (already present)
  • octokit: GitHub API (already present)

Configuration Files Updated

  • .github/copilot-instructions.md: Complete bot architecture guide for AI agents
  • eslint.config.mjs: Added .md files to ignore list
  • shared/src/types.ts: Extended with new interfaces
  • bot/package.json: Added new dependencies

Next Steps / TODO

  1. XPI Validation: Uncomment XPI download/verify in processor for strict validation
  2. GitHub Workflow: Add .github/workflows/sync.yml for scheduled builds
  3. Testing: Add unit tests for merger logic and error scenarios
  4. Caching: Implement HTTP cache directory (.cache/http-cache.json)
  5. Incremental Builds: Use ETag/Last-Modified headers for bandwidth optimization

Usage Examples

# Build all plugins
pnpm exec tsx bot/src/cli.ts

# Build specific plugins
pnpm exec tsx bot/src/cli.ts build plugin-id-1 plugin-id-2

# Check mode for PR validation
pnpm exec tsx bot/src/cli.ts check

# Display help
pnpm exec tsx bot/src/cli.ts --help
