agentic

Run Claude Code on any model, with a budget.

agentic wraps Claude Code in a thin local router. Your sessions look and feel exactly like claude — same TUI, same tools, same updates — but the model behind them can be Anthropic, OpenAI, xAI, or anything OpenAI-compatible (Ollama, vLLM, OpenRouter, DeepSeek, Groq). Every token is metered, priced, and checked against budgets you set.

agentic                  # Claude Code, tracked, on your default profile
agentic -p cheap         # same session, cheaper models
agentic --model grok     # one-off model override
agentic cost             # where did today's $4.31 go?

Why

Claude Code is a great harness, and it keeps getting better — forking it means losing that. But it only talks to one provider, and it doesn't answer two questions you eventually ask: how much did that session cost? and can I run the cheap parts on a cheap model?

agentic answers both without touching Claude Code itself. Claude Code officially supports pointing at a gateway via ANTHROPIC_BASE_URL; agentic is that gateway, plus the CLI around it.

Compared to other options

There are three ways people solve "I want Claude Code but not locked to one provider":

	agentic	claude-code-router / claude-code-proxy forks / LiteLLM	OpenCode, Crush, Goose, Aider
Harness	Real Claude Code, unmodified, auto-updating	Real Claude Code, unmodified	Different harness entirely — own prompts, tools, TUI
Runs as	Static Go binary, no daemon (leader election over a fixed port)	Daemon / server process you deploy and administer	Standalone CLI you run instead of Claude Code
Cost & budgets	First-class CLI: agentic cost, live statusline, hard-stop daily/weekly/monthly budgets	Usually a dashboard (LiteLLM) or not built in	Varies by tool, rarely budget-gated
Model routing	Aliases + a built-in LLM-classifier tier router (auto), sticky per turn	Rule-based routing configs; no classifier-based tiering	Manual model switch, no auto-routing
Memory / cross-instance	Composes with clauder — separate binary, optional	Not their concern	Varies

The short version: agentic doesn't try to be a better harness than Claude Code — it keeps Claude Code exactly as Anthropic ships it and only swaps what's behind ANTHROPIC_BASE_URL. If you want a different agent loop altogether, OpenCode/Crush/Goose/Aider are the right layer to look at instead. If you want a gateway you deploy and administer for a team, LiteLLM is a more mature choice for that. agentic is for a single developer who wants claude, unmodified, with a budget and a cheap-model escape hatch, installed in one command and running with nothing to operate.

How it works

agentic (launcher) ──▶ claude (unmodified, auto-updating)
                          │  ANTHROPIC_BASE_URL
                          ▼
                   local router (127.0.0.1)
                   ├─ anthropic: byte-faithful passthrough
                   ├─ openai dialect: full request/stream translation
                   ├─ usage log (SQLite) + pricing
                   └─ budget gate
                          ▼
        Anthropic · OpenAI · xAI · Ollama · vLLM · OpenRouter · ...

There is no daemon. The first agentic session binds the router port and serves everyone; when it exits, another running session takes over within a couple of seconds. The last session out turns off the lights.

Model names are aliases you define. Claude Code treats model IDs as opaque strings, so ANTHROPIC_MODEL=grok flows straight through and the router resolves it. Anything starting with claude- passes through to Anthropic untouched — background tasks keep working even when your main model is something else entirely.

Install

curl -fsSL https://raw.githubusercontent.com/maorbril/agentic/main/install.sh | sh
agentic setup

Or from source: go install github.com/maorbril/agentic@latest

To update later, run agentic update (or agentic update --check to see if one's available without installing it). This updates agentic itself; Claude Code keeps auto-updating on its own regardless.

Configure

Everything lives in ~/.agentic/config.yaml, and everything is editable from the terminal:

agentic providers add openai --type openai --base-url https://api.openai.com/v1 \
    --key-env OPENAI_API_KEY --max-tokens-param max_completion_tokens
agentic models add gpt --provider openai --id gpt-5.2 --reasoning effort --max-output 16384
agentic models test gpt          # 1-token probe: did I configure it right?
agentic budget set --daily 25

Edits apply to live sessions immediately — the CLI hot-reloads the running router.

A profile bundles a main model, a small/fast model for background tasks, tier mappings (so /model opus resolves inside the profile), and optional budgets:

profiles:
  main:  {model: sonnet, small_fast: haiku, tiers: {opus: opus, sonnet: sonnet, haiku: haiku}}
  cheap: {model: gpt, small_fast: gpt, budget: {daily: 5.00}}
  local: {model: qwen, small_fast: qwen}
  subscription: {passthrough: true}   # plain claude, subscription billing, no tracking

Dynamic routing

Instead of picking models by hand, let a cheap LLM triage every task:

agentic routing set auto --classifier haiku \
    --deep opus --standard sonnet --light qwen

auto now behaves like a model (/model auto, or profiles: {model: auto}). On each new user turn, the classifier reads the request and assigns a tier — planning and hard debugging go deep, ordinary coding goes standard, mechanical edits and verification go light. The decision sticks for the rest of the turn (tool results don't re-trigger it), so a task never flips models mid-flight. Classification failures fall back to --default (standard), and every decision is logged:

$ grep autoroute ~/.agentic/router.log
... alias=auto tier=deep model=opus
... alias=auto tier=light model=qwen

agentic cost --by model then shows how spend actually distributed across tiers. Each classification costs one tiny request to the classifier model (~$0.0005 with haiku).

Budgets

Daily, weekly, and monthly caps — global and per profile. When a cap is hit, the router refuses the next request with a clear message that shows up right in the Claude Code TUI; in-flight responses are never cut. Warnings surface in the statusline (agentic setup registers it), which shows live session and daily spend:

main · sonnet · sess $0.84 · day $4.31/$25 [██░░░░]

agentic cost breaks spend down by model, profile, or session, and --json gives you the raw rows.

The fine print

Two things you should understand before routing through agentic:

• Billing. Traffic through the router is billed to API keys, not your Claude Pro/Max subscription. OAuth credentials are never proxied. For subscription billing, use a passthrough: true profile — normal claude, no tracking.
• Fidelity. Non-Anthropic models work through translation, but Claude Code's prompts and tool patterns are tuned for Claude, so expect them to be clunkier in the main loop. They shine as cheap workhorses for background tasks and subagents. Specific gaps: no prompt caching on OpenAI-dialect backends (provider-side implicit caching still shows up as cache reads), thinking blocks are display-only, Anthropic server tools (web search, code execution) are unavailable on translated models, top_k is dropped, stop sequences truncate to four, and token counting for translated models is a deliberate ~15% overestimate so auto-compact fires early instead of overflowing context. Set max_output on models whose output cap is below what Claude Code requests (it asks for 32K).

Works with clauder

If clauder is installed, agentic launches sessions through clauder wrap --slave, so your instances get persistent memory, can message each other, and run with clauder's auto-approved tool set for autonomous operation. Launch with --no-clauder for a bare claude session. The two tools are independent; each works without the other.

Commands

Command	What it does
agentic [-p profile] [--model alias] [-- args]	launch Claude Code (args after -- go to claude)
agentic setup	first-run config, token, statusline registration
agentic cost [--week|--month] [--by model|profile|session]	spend report
agentic models add/list/remove/test/update-prices	model aliases
agentic providers add/list/remove	upstream providers
agentic profiles list/show · agentic budget set	profiles and caps
agentic config get/set	any config key
agentic router run/status	headless router / who's leader
agentic doctor	diagnose the installation
agentic update [--check]	update agentic itself to the latest release

Keys

Provider keys are referenced by environment variable name. They resolve in order: process environment → ~/.agentic/env (a KEY=value file, mode 0600, created by setup). Put keys in ~/.agentic/env — the router reads it directly, so sessions work no matter which shell launched them, and the config file never holds a secret.

Security notes

The router binds 127.0.0.1 only and requires a per-install token (created by setup, mode 0600), so other local processes can't spend on your keys.
