Repository guidance

IPTVnator is an Angular/Electron IPTV player with a browser/PWA runtime. These are the common instructions for all coding agents. Read the relevant contracts below before changing a subsystem; do not load every document.

Bootstrap and commands

• Use the Node version in .nvmrc and the repository's pnpm version.
• In a fresh worktree, run pnpm install --frozen-lockfile before Nx discovery, tests, lint or builds. Each worktree needs its own install.
• Repeat the install after checkout changes, pulls, resets or rebases. Compare pnpm-lock.yaml with node_modules/.pnpm/lock.yaml; a difference means stale dependencies. Do not diagnose stale modules as application failures.
• Verify discovery with pnpm nx show projects. Inspect the owning project's targets before choosing checks. Prefer the smallest relevant Nx target.
• Development: pnpm run serve:frontend or pnpm run serve:backend.
• Tests: pnpm nx test <project>; lint: pnpm nx lint <project>.
• Find checks and E2E commands in the validation map.
• Packaging, native dependencies and runtime patches have additional contracts in the context map; read them before dependency or release changes.

Implementation invariants

• Use scoped aliases from tsconfig.base.json, such as @iptvnator/services. Do not introduce legacy bare aliases or bypass public project boundaries.
• Nx projects keep scope:*, domain:* and type:* tags. Shared cross-project files must belong to a project. SCSS imports need explicit hash dependencies.
• Target under 300 production TypeScript lines; the hard limit is 400 (1200 for tests), excluding comments/blanks. Never add entries to the legacy baseline.
• Preserve existing persisted data. Users may skip releases: migrations must apply in dependency order, preserve data and be safe on repeated startup. Test actual historical SQLite schemas, not only SQL mocks.
• Choose runtime behavior through the relevant capability contract; a generic window.electron check does not prove that a particular bridge is available.
• Use shared redacting logging before emitting settings, portal or trace data. Never log credentials or expanded SQL/bound values.
• Keep UI consistent with the shared guidelines. Read the repository UI/theme skills before changing user-visible Angular views or shared styles.

Validation and completion

• Before finishing, assess affected projects and test impact. Bug fixes normally include regression coverage that fails before the fix and passes afterwards.
• Update stale tests, fixtures and E2E flows when behavior changes. Run targeted unit checks and affected E2E for routing, persistence, playback and user flows.
• Electron-only IPC, database, packaging, players and filesystem changes need Electron E2E where available, otherwise CDP/manual validation with a reason.
• Report checks and results, any skipped checks with reasons, documentation changes, and whether a release note was added or why it was unnecessary.
• Every user-visible change needs a note under .changes/; follow the release-note format and the repository release-notes skill. Docs, tests, CI and behavior-preserving refactors do not need a note. Apply no-release-note on exempt PRs touching runtime code.
• Validate notes with pnpm run release:notes:validate. Release publication has separate ordered gates; follow the release-cut skill and release contract.
• Before the first push of a pull-request branch, and before each later push to an open pull request, pass the local review gate: Codex and Greptile CLI reviews of the committed branch, repeated until both are clean. CI and the GitHub review bots confirm a branch; they are not its first reviewer.

Keep guidance small and canonical

• Update the affected subsystem's canonical document after meaningful changes. Prefer an existing authoritative doc; keep user/developer entry points in README and detailed contracts in architecture docs or a module README.
• Add to this file only repository-wide rules and navigation. Implementation details, incident history and multi-step procedures belong in linked docs. Do not duplicate subsystem contracts here or in CLAUDE.md.
• AGENTS.md is the single source of common rules. CLAUDE.md imports it and contains only Claude-specific guidance. Limits: 200 lines / 16 KiB here, 30 lines / 2 KiB for CLAUDE.md. Do not raise loading limits to fit more prose.
• Read the context map when ownership is unclear. Read each affected domain for cross-domain tasks, not the whole map's documents.
• Preserve exceptions and rationale when moving knowledge. Correct stale facts against code; do not silently discard a contract. Maintenance details are in the agent workflow.
• Never run whole-file prettier --write on AGENTS.md, CLAUDE.md or docs/**. Edit only intended lines; upstream Markdown is not uniformly Prettier-clean.
• After changing guidance, run pnpm run agents:validate; after editing a repository skill or a literal path it documents, run pnpm run skills:validate. Keep release-cut and release-notes copies byte-identical for Codex and Claude.
• Save finalized plans only in .plans/YYYY-MM-DD-short-topic.md; if a filename exists, append -2, -3, etc. Respect active mode restrictions on file writes; if writing is forbidden, save the approved plan when execution starts.

Downloads, TMDB, multi-source, workspace, backup, website	Context map
Release or packaging metadata	Release pipeline, release-cut skill

Repository skills live in .codex/skills/. Their frontmatter owns trigger conditions; use the context map to locate a relevant skill. Read its linked contract before editing. A missing optional global skill/tool is not a blocker: use repository documentation and available CLI discovery.

General Guidelines for working with Nx

• For workspace exploration, use the nx-workspace skill when available; otherwise inspect project-local project.json files, pnpm nx show projects and pnpm nx graph.
• Run project tasks through local pnpm nx, not a global Nx installation.
• Use the Nx MCP server when available; otherwise use CLI discovery.
• Check node_modules/@nx/<plugin>/PLUGIN.md for plugin guidance when present.
• Never guess unfamiliar flags: consult --help or available nx_docs.

Scaffolding and generators

• Use the nx-generate skill first when available. Otherwise discover the generator with local Nx help and follow repository boundary rules.

When to use nx_docs

• Use available nx_docs for migrations, unfamiliar configuration and flags.
• Basic task syntax does not require a docs lookup; generator discovery belongs to the generator skill or local CLI help.
