What is deepagents-setup-configuration?

A setup and troubleshooting guide for Deep Agents, an agent framework built with Python or JavaScript. It includes built-in planning, file handling, checkpoints, and delegation to subagents.

Use it to scaffold or validate Deep Agent projects, configure middleware and storage, add human approval steps, or migrate from older agent APIs.

It helps you choose the right setup, create a starter project, check its configuration, and migrate older agent code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00095	$0.01713
Opus 5	$0.00048	$0.00856
Sonnet 5	$0.00019	$0.00343
Haiku 4.5	$0.00010	$0.00171

Security

Grade A, and why

deepagents-setup-configuration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (assets/examples/basic-deep-agent/agent.py, assets/templates/deep-agent-simple/agent.py, scripts/init_deep_agent_project.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Deep Agents Setup and Configuration

Deep Agents are an agent harness on top of LangChain + LangGraph with built-in planning, filesystem context management, and subagent delegation.

Use This Skill When

You need a Deep Agent quickly (Python or JavaScript).
You need subagents, filesystem-backed context, planning (write_todos), or long-term memory patterns.
You need migration guidance from older create_react_agent flows.
You need to scaffold a starter project with repository scripts.
You need to statically validate an agent.py / agent.js / agent.ts config.
You need safety checks before open-sourcing Deep Agents examples/templates.

Tooling In This Skill

scripts/init_deep_agent_project.py: scaffolds Python/JS projects with templates.
scripts/validate_deep_agent_config.py: static checks for Deep Agent config quality.
references/deep-agents-reference.md: detailed API, middleware, backends, migration, troubleshooting.
assets/templates/deep-agent-simple/: minimal Python starter template.
assets/examples/basic-deep-agent/: richer Python example.

Recommended Workflow

Decide if Deep Agents is the right abstraction.
Scaffold with init_deep_agent_project.py (Python or JS).
Customize tools, prompt, backend, subagents, and persistence.
Run validate_deep_agent_config.py.
Use references/deep-agents-reference.md for advanced configuration.
Run the generated project and verify traces/behavior.

Choose The Right Abstraction

Need	Deep Agents	LangChain `create_agent`	LangGraph
Built-in planning/filesystem/subagents	✅ Best fit	⚠️ Manual middleware setup	❌ Manual graph design
Fast path for complex multi-step tasks	✅	⚠️	⚠️
Fully custom graph topology	❌	❌	✅ Best fit
Minimal/simple agent (1-3 steps)	⚠️ Overhead	✅ Best fit	⚠️

Initialize A Project

Use repo-local scripts and prefer uv run.

# Python simple template
uv run skills/deepagents-setup-configuration/scripts/init_deep_agent_project.py my-agent --language python --template simple --path skills/

# Python with subagents
uv run skills/deepagents-setup-configuration/scripts/init_deep_agent_project.py my-agent --language python --template with-subagents --path skills/

# Python CLI-config template (memory/checkpointer toggles)
uv run skills/deepagents-setup-configuration/scripts/init_deep_agent_project.py my-agent --language python --template cli-config --path skills/

# JavaScript template
uv run skills/deepagents-setup-configuration/scripts/init_deep_agent_project.py my-agent --language javascript --template simple --path skills/

What ships with it

10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

deepagents-setup-configuration is a skill published in the GitHub repository soba-labs/langchain-agent-skills (106 stars, last pushed 24d ago), licensed MIT. It adds 95 tokens to every session and 1,713 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
