ENGINEERING DIRECTIVE • EXTENSION PIPELINE

SCRIPT INFRASTRUCTURE

I build and maintain Anki add-on pipelines with a focus on strict modularity, memory efficiency, and deterministic UI execution. Like laying solid structural footings for a physical workshop, your Python extensions must integrate directly with the core hook lifecycle without bloating SQLite transactions or creating hotkey collisions. This blueprint provides a concrete overview of tested add-on installations, structured configuration objects, and hotkey ergonomics tailored for high-volume retention workflows.

0.12s Target Latency Limit

Maximum card render latency permitted across 50,000 active cards.

100% Local SQLite Integrity

All modifications execute inside single transaction blocks to prevent card corruptions.

12 Keys Spatial Ergonomic Map

Single-hand left-cluster navigation designed to eliminate wrist rotation fatigue.

DATA STRUCTURE • JSON SCHEMA

Declarative Add-on Configuration

Anki's built-in mw.addonManager.getConfig(__name__) parser provides atomic synchronization with the user preferences file. When configuring scripts for heavy production review, you must enforce strict typing and disable redundant telemetry pings.

For advanced templating, combine this configuration approach with the design patterns outlined in our Card Template Architecture & CSS Syntax guide to ensure your card layouts match your script capabilities.

Left-Cluster Spatial Layout

Reviewing 500 to 1,000 cards per day introduces repetitive strain if fingers traverse across the full alphanumeric layout. By consolidating operational triggers (Suspend, Bury, Tag) directly above the answer keys (Again, Good), your wrist remains anchored in a static, neutral posture.

We coordinate these custom bindings with the mathematical interval targets calculated in our Interval Scheduling & FSRS Algorithm Calculations module to eliminate grading hesitations.

Configured via customized reviewer_shortcuts.py injection hook.

DIAGNOSTIC PROTOCOLS • FAILURE RESOLUTION

SQLite & Threading Exception Matrix

Standard procedures for resolving module collisions, corrupt indexes, and Qt UI thread freezes.

1. Fatal DB Lock: `sqlite3.OperationalError: database is locked`

Critical Error

Occurs when an external sync script or AnkiConnect instance triggers a secondary write operation while a primary background vacuum or sync task is actively holding the SQLite handle.

Remediation: Wrap API handlers with mw.col.db.execute() transaction locks and implement exponential backoff retry parameters within the local sync routine.

2. Qt GUI Block: `QThread: Destroyed while thread is still running`

Thread Collision

Triggered when closing modal dialogs before asynchronous image fetch routines have finished resolving network requests.

Remediation: Inherit from anki.hooks.QueryOp to guarantee proper garbage collection upon deck browser state changes.

3. Legacy Field Collisions in Hierarchical Decks

Schema Mismatch

Occurs during batch deck restructuring. Review our structural taxonomy guidelines in Deck Taxonomy & Information Hierarchy and align your routine with the operational protocols in Active Recall Protocols & Daily Review Calibration.

Remediation: Run Check Database within Anki Tools and prune orphan schema tags from the database header.

“I do not hand off unverified scripts or install bloated package lists that crash during updates. Every hook is reviewed locally against SQLite, tested across 50,000 flashcards, and tuned for instant key responses.”

Need a Clean Technical Setup?

I configure and verify custom add-on stacks, remove plugin conflicts, and optimize database queries directly for your learning workstation. No middleman agencies or monthly retainers.
