Package acp implements the Agent Client Protocol (ACP) surface for ZERO: a JSON-RPC 2.0 peer spoken over stdio (newline-delimited JSON) so editors such as Zed, JetBrains, and Neovim can drive ZERO's agent core as a backend.

Package agentinit builds the bootstrap prompt for the guided /init flow that generates a project AGENTS.md.

Package browser opens a URL in the user's default web browser.

Package credstore persists provider API keys outside config.json so secrets are not written to disk in cleartext.

Package cron implements a small, dependency-free standard 5-field cron parser and next-run evaluator for the `zero cron` scheduler.

Package daemon implements zero's long-running daemon/server mode: a local control server that supervises a pool of headless `zero exec` worker processes and routes multiple agent sessions to them over an owner-only local socket.

Package errhint classifies provider/model failures into a few user-actionable categories and turns them into a one-line "next step" hint.

Package imageinput is the single shared loader for local image files used by every input surface (CLI exec --image, TUI /image).

Package keyring provides a small, dependency-free secret store backed by the operating system's native credential tooling: the `security` keychain CLI on macOS and `secret-tool` (libsecret) on Linux.

Package lsp is a direct Language Server Protocol client: ZERO spawns the language server itself and speaks LSP JSON-RPC over stdio, so an unattended run (cron/CI, no open editor) can still see real compiler diagnostics.

Package minify produces a denser, token-cheaper VIEW of a source file for read-only exploration.

Package notify emits dep-free terminal notifications (BEL and/or OSC-9 desktop notifications) when Zero finishes a turn or needs user input.

Package oauth is zero's reusable OAuth 2.0 engine.

Package observability provides dependency-free crash capture for the CLI: a recovered panic is written to a local crash report (timestamp, label, stack) and surfaced to the user as a brief notice instead of a raw stack trace.

Package providerhealth validates provider configuration and optionally probes the configured provider endpoint with a bounded, non-generating request.

ChatGPT-specific login flow.

Package reasoning models how each provider's models expose reasoning-effort control.

Package repoinfo characterizes a repository from local git commands only (no network).

Package repomap scans a workspace into a compact, deterministic repository map.

Package secrets provides a lightweight, dependency-free scanner for high-confidence secret patterns (cloud keys, provider tokens, private keys, JWTs).

Package securefile provides AES-256-GCM encryption-at-rest for small on-disk blobs under a per-user random secret persisted (0600) beside the data file.

Package skills discovers reusable instruction "skills" stored on disk as */SKILL.md files.

Package swarm adds a multi-agent SWARM on top of zero's single sub-agent mechanism (internal/specialist): an orchestrator can spawn and coordinate MULTIPLE specialist members that run concurrently, communicate via per-agent mailboxes, and hand work off.

file_view.go is the drill-in view for a touched file, opened from the FILES sidebar section (files_panel.go).

Package usercommands loads user-defined slash commands from markdown files.

Package workspaceindex provides shared deterministic workspace scanning primitives for repo intelligence, tools, and context accounting.

Package workspaceseed builds a compact, deterministic workspace context seed for future agent prompt/session wiring.
