Claw onboarding: missing .env.example and undocumented TAVILY_API_KEY cause silent failure on first run

[Dhivya-Bharathy]

Severity

Severity	Category	Issue Type
Medium	Developer Experience / Documentation	Missing onboarding artifact + undocumented required variable

---

Summary

Two related onboarding gaps affect first-time PraisonAI Claw users:

1. No .env.example template exists in the repository root. New users have no reference for which environment variables are required, leading to silent failures.
2. TAVILY_API_KEY is not documented anywhere in the setup guide, README, or any template — yet the Claw dashboard's default web-search tool requires it. Users see a cryptic tool error with no indication that a second API key is needed.

Both gaps cause new users to fail at the first agent run with no actionable error message pointing to the fix.

---

Affected Components

Component	Location	Issue
Repository root	/	No .env.example file
README.md	Setup / Configuration section	TAVILY_API_KEY not mentioned
praisonai claw web search tool	Runtime	Fails silently when TAVILY_API_KEY is absent
Claw dashboard UI	Agent creation wizard	No inline hint for required API keys

---

Expected vs Actual Behavior

	Behavior
Expected	A .env.example file at the repo root lists every required variable with a description and placeholder value
Actual	No such file exists; users must discover variables through source code inspection or trial-and-error

	Behavior
Expected	README / Claw setup guide explicitly states: TAVILY_API_KEY=<your key> is required for the built-in web-search tool
Actual	TAVILY_API_KEY is not mentioned in any user-facing documentation; the tool fails with a non-actionable error

---

Reproduction Steps

Gap 1 — Missing .env.example:

git clone https://github.com/MervinPraison/PraisonAI.git
ls PraisonAI/.env.example   # → No such file or directory

A new user has no template to copy. They must guess which variables are needed.

Gap 2 — Undocumented TAVILY_API_KEY:

# Start Claw with only OPENAI_API_KEY set (as documented)
export OPENAI_API_KEY=sk-...
praisonai claw

# In the Claw dashboard, create a default agent and ask it to search the web.
# Observed error (no mention of TAVILY_API_KEY):
#   Tool execution failed: TavilySearchResults: TAVILY_API_KEY environment variable not set

The error message does not tell the user where to get a Tavily key or that it is optional vs required.

---

Root Cause Analysis

• No .env.example was ever added to the repository. Issue Feature: Frictionless onboarding — praisonai setup wizard + install.sh post-install hook #1451 noted a related documentation gap and was closed, but the artifact itself was never created.
• tavily-python is a hard dependency in the Claw extras (pyproject.toml), but TAVILY_API_KEY is not referenced in README.md, INSTALL.md, or any quick-start guide.

The combination means a user who follows the documented setup exactly will experience a failing tool on their first agent run with no path to resolution.

---

Impact Analysis

Dimension	Detail
Affected users	All first-time Claw users
Failure mode	Web-search tool errors with no actionable guidance
Discoverability	Very low — requires reading praisonaiui/tools/ source code
Fix complexity	Very low — create one file, add two lines to README

---

Why This Matters

.env.example is a widely recognised convention (used by Rails, Next.js, Docker Compose, and most open-source SaaS starters). Its absence signals to new contributors and enterprise evaluators that the project is not onboarding-ready. Combined with the undocumented Tavily key, a user's very first agent interaction fails — the worst possible first impression for an AI agent framework.

---

Suggested Fix

1. Create .env.example at the repository root:

# === Required ===
OPENAI_API_KEY=sk-...          # OpenAI key for LLM calls

# === Required for Claw web-search tool ===
TAVILY_API_KEY=tvly-...        # Get yours at https://app.tavily.com

# === Optional: Claw dashboard ===
PRAISONAI_ALLOW_LOCAL_TOOLS=0  # Set to 1 to enable local shell tools (security risk)

# === Optional: Memory backend ===
# MEM0_API_KEY=...
# REDIS_URL=redis://localhost:6379

# === Optional: Observability ===
# LANGFUSE_SECRET_KEY=...
# LANGFUSE_PUBLIC_KEY=...

2. Add a "Required Environment Variables" section to README.md (Claw section):

## Required Environment Variables

| Variable | Required | Description |
|----------|----------|-------------|
| `OPENAI_API_KEY` | Yes | OpenAI API key for all LLM calls |
| `TAVILY_API_KEY` | Yes (Claw) | Tavily key for the built-in web-search tool. Get one free at https://app.tavily.com |

Copy `.env.example` to `.env` and fill in your keys before running `praisonai claw`.

Backward Compatibility

Fully additive — no existing behaviour changes.

Acceptance Criteria

• .env.example added to the repository root with all variables listed in the table above
• TAVILY_API_KEY documented in the Claw section of README.md with a link to obtain a free key
• Claw quick-start guide (if separate) updated to reference .env.example
• Optionally: the Claw dashboard's web-search tool emits a user-friendly message when TAVILY_API_KEY is absent, e.g. "Web search requires TAVILY_API_KEY. See .env.example."
