At a glance

A skill your agent uses when changing Electron SQLite IPC, database-worker operations, request-scoped progress or cancellation, worker packaging, or runtime verification of non-EPG database work.

  • Changing Electron SQLite IPC

  • Calls pnpm
  • Database-worker operations

What it does

Iptvnator Sqlite DB Worker is an agent skill from 4gray/iptvnator. Use when changing Electron SQLite IPC, database-worker operations, request-scoped progress or cancellation, worker packaging, or runtime verification of non-EPG database work.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases. It works with SQLite. The repository describes itself as: :tv: Cross-platform IPTV player application with multiple features, such as support of m3u and m3u8 playlists, favorites, TV guide, TV archive/catchup and more. The licence is MIT.

When your agent uses it

  • Changing Electron SQLite IPC
  • Database-worker operations
  • Request-scoped progress
  • Worker packaging

Example prompts

  • “/iptvnator-sqlite-db-worker”

What it can do on your machine

Read from SKILL.md and the folder at commit 6c8f502. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pnpm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Iptvnator Sqlite DB Worker loads about 824 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 286 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~824

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

IPTVnator SQLite DB Worker

Ownership and Flow

  • Renderer service: libs/services/src/lib/database-electron.service.ts
  • Preload API: apps/electron-backend/src/app/api/main.preload.ts
  • IPC handlers: apps/electron-backend/src/app/events/database/
  • Client: apps/electron-backend/src/app/services/database-worker-client.ts
  • Protocol: apps/electron-backend/src/app/workers/database-worker.types.ts
  • Thin dispatcher: apps/electron-backend/src/app/workers/database.worker.ts
  • Connection: apps/electron-backend/src/app/workers/database.worker-connection.ts
  • Runtime paths: apps/electron-backend/src/app/workers/worker-runtime-paths.ts
  • SQL operations: apps/electron-backend/src/app/database/operations/
  • Shared schema: libs/shared/database/src/lib/schema.ts
  • Bundler: apps/electron-backend/build-worker.js
  • Canonical guide: docs/architecture/sqlite-db-worker.md

The chain is renderer DatabaseService → preload IPC → main event handler → DatabaseWorkerClient and its request protocol → worker dispatcher → worker connection → operation module → shared @iptvnator/shared/database/schema, then response or request-scoped event back to the originating renderer. Keep SQL-heavy logic in operation modules and the worker entrypoint focused on dispatch/orchestration.

The build script produces three bundles: EPG parser, database, and playlist refresh. EPG parsing stays in its dedicated worker. Do not silently migrate lightweight download handlers or EPG-specific main-process query/mapping/fetch handlers as part of unrelated database work.

Identity, Progress, and Cancellation

requestId is generated for every client request and correlates worker event/response transport. operationId is the renderer-visible identity for long-operation progress and cooperative cancellation.

Tracked operations are save content, delete Xtream content, restore Xtream user data, delete playlist, and delete all playlists. The first four are cancellable. Delete-all is deliberately tracked with cancellable: false.

Cancellation is cooperative at chunk checkpoints. Committed chunks remain committed and the request finally rejects with AbortError. For the operation/busy lifecycle, only a terminal completed/error/cancelled event settles UI state; a cancel-requested flag may update immediately.

Inside synchronous better-sqlite3 transactions, prepared writes must use .run(). .execute() defers work and can commit a silent no-op.

Rebuild and Verify

After worker source changes:

bash
pnpm nx test electron-backend
pnpm nx run electron-backend:build-worker
stat dist/apps/electron-backend/workers/database.worker.js

Confirm the artifact timestamp, restart Electron, then run the closest Electron E2E or CDP workflow.

For SQL output, IPTVNATOR_TRACE_DB=1 and IPTVNATOR_TRACE_SQL=1 emit only fixed, allowlisted statement types through the shared redacting summary in libs/shared/logging/src/lib/sql-trace-summary.ts; never log expanded SQL or bound values. DB transport traces remain separately redacted.
