TARGET: $ARGUMENTS
============================================================
CONFIGURATION
Before starting, detect or load configuration:
-
Check for config file at ./.free-keys.json (project root) or
~/.config/free-keys/config.json (global). Use the first one found.
-
Config schema (all fields optional — sensible defaults apply):
{
"env_file": ".env",
"litellm": {
"enabled": false,
"config": "~/llm-stack/litellm-config.yaml",
"env": "~/llm-stack/.env",
"compose": "~/llm-stack/docker-compose.yml",
"proxy_url": "http://127.0.0.1:4000"
},
"gateway": {
"enabled": false,
"config": "~/my-gateway/config.json",
"env": "~/my-gateway/.env"
},
"extra_env_files": []
}
-
Defaults when no config exists:
- Save keys to
.env in the current working directory
- LiteLLM integration: disabled (auto-enabled if
litellm-config.yaml is
found in cwd or ~/llm-stack/)
- Gateway integration: disabled
- No extra env files
-
Auto-detection: If no config file exists, scan for:
litellm-config.yaml or litellm_config.yaml in cwd → enable LiteLLM
docker-compose.yml with litellm service in cwd → enable LiteLLM
gateway*.json in cwd → enable gateway

============================================================
PHASE 1: HEALTH CHECK
- Load keys from the configured env file(s). Source
.env in cwd first,
then any extra env files from config. Also check the current shell environment.
- For each provider in the registry, check if the env var exists and is non-empty
and is not "dummy".
- For providers that HAVE keys, run a quick validation:
- Make a minimal chat completion request (max_tokens=5, message="hi")
- For Gemini: use the Google AI Studio OpenAI-compatible endpoint
- For all others: standard OpenAI-compatible Authorization: Bearer header
- Mark as OK (working), EXPIRED (auth error), or RATE_LIMITED
- Produce a status table:
PROVIDER STATUS DETAIL
-------- ------ ------
Groq OK 41 tokens used
Cerebras OK 12 tokens used
Mistral MISSING -- sign up at https://console.mistral.ai
DeepSeek EXPIRED credit balance too low
If $ARGUMENTS is "check" or "health", stop here after showing the table.
============================================================
PHASE 2: GUIDED PROVISIONING
For each MISSING or EXPIRED provider (sorted by value — persistent free tiers first,
then credit-based):
Priority order for provisioning:
- Groq (free forever, fast)
- Cerebras (free forever, fast)
- Google AI Studio (free forever, Gemini)
- OpenRouter (free forever, 29+ models)
- Mistral (free forever, 1B tokens/mo)
- DashScope (free quota, Qwen models)
- xAI (generous credits)
- DeepSeek (free tokens)
- Together AI (signup credits)
- All others
For each missing provider:
a) Tell the user what they are signing up for:
[3/11] Mistral -- Free experiment plan, 1B tokens/mo
Opening signup page... (requires phone verification)
b) IMMEDIATELY open the signup URL in the user's browser using Bash:
xdg-open "URL" 2>/dev/null || open "URL" 2>/dev/null || echo "Open: URL"
This MUST happen automatically — do NOT ask before opening.
Use the DIRECT API key page URL where possible (not just homepage).
c) Ask the user to paste their API key with a single question.
The question should be brief: "[Provider] API key:"
with options: ["Skip this provider", "Skip all remaining"]
The user selects "Other" to paste their key — this is the expected flow.
d) If the user pastes a key (selected "Other" and typed it):
- Immediately validate it by making a test request using Bash + curl
- If valid: save it (Phase 3), print a one-line success, and move on
- If invalid: tell the user the error and ask once more (same question)
- On second failure: skip and move on
e) If the user chose "Skip", move to next provider immediately.
If "Skip all remaining", jump to Phase 4.
IMPORTANT: Keep the flow FAST. One browser open + one paste per provider.
Do not over-explain. Do not ask extra questions. Do not wait between providers.
============================================================
PHASE 3: SAVE AND WIRE
For each newly validated key:
-
Save to env file — Update the key in the configured env file (default: .env in cwd).
Also update any extra_env_files from config.
Use the Edit tool to update existing lines or append new ones.
If a line like KEY_VAR= or KEY_VAR=old_value exists, replace it.
If the var does not exist in the file, append it.
-
LiteLLM integration (only if enabled in config or auto-detected):
- Update the LiteLLM env file with the new key
- Add model entries to litellm config YAML if the provider is not already present
- Follow the existing format in the file
- Update docker-compose if it does not pass through this env var
Key model mappings to add per provider:
- Mistral: mistral-large (mistral-large-latest), mistral-small (mistral-small-latest), codestral (codestral-latest)
- xAI: grok-4 (grok-4), grok-3-mini (grok-3-mini-fast)
- DeepSeek: deepseek-chat (deepseek-chat), deepseek-reasoner (deepseek-reasoner)
- Together: together-llama-405b (meta-llama/Llama-3.1-405B-Instruct-Turbo)
- SambaNova: sambanova-llama-405b (Meta-Llama-3.1-405B-Instruct)
- Fireworks: fireworks-llama-405b (accounts/fireworks/models/llama-v3p1-405b-instruct)
- NVIDIA: nvidia-llama-70b (meta/llama-3.3-70b-instruct)
- Cohere: cohere-command-r-plus (command-r-plus)
-
Gateway integration (only if enabled in config):
- Update the gateway config JSON following the existing format
- Update the gateway env file with the new key
============================================================
PHASE 4: RESTART AND VERIFY
-
If LiteLLM is enabled:
-
Run a final health check on all providers (same as Phase 1).
-
Print summary:
=== FREE KEYS PROVISIONING COMPLETE ===
Newly added: 3 (Mistral, xAI, DeepSeek)
Already working: 5 (Groq, Cerebras, Gemini, DashScope, OpenRouter)
Skipped: 4 (Cohere, SambaNova, Fireworks, NVIDIA)
Failed: 1 (DeepSeek -- out of credits)
Free models now available: ~58
Estimated free capacity:
- ~3,200 requests/day across all providers
- ~2B tokens/month (Mistral alone = 1B)
Keys saved to: .env
If LiteLLM was enabled, also show:
LiteLLM config updated: ~/llm-stack/litellm-config.yaml
LiteLLM restarted and healthy.
============================================================
PHASE 5: SMART ROUTING (LiteLLM only)
Skip this phase entirely if LiteLLM is not enabled.
After adding new keys, verify smart aliases work through LiteLLM:
- Test each smart alias through the proxy:
curl -s <proxy_url>/chat/completions \
-H "Content-Type: application/json" \
-d '{"model":"free-best","messages":[{"role":"user","content":"hi"}],"max_tokens":5}'
- Test aliases if they exist in the config: free-best, free-fast, free-code,
free-vision, free
- Report which aliases are working and which providers they routed to.
When adding a new provider, also add its models to relevant smart alias groups
in the LiteLLM config (with rpm/tpm limits) if aliases exist.
============================================================
PHASE 6: DISCOVER NEW PROVIDERS
Only runs when $ARGUMENTS is "discover".
Use web search to find NEW free LLM API providers not already in the registry:
-
Search for:
-
For each new provider found, report:
- Provider name and URL
- What free tier they offer
- Which models are available
- Whether they have an OpenAI-compatible API
-
Offer to add discovered providers to the provisioning flow.
-
If the user confirms, run Phases 2-4 for the new providers.
============================================================
SPECIAL MODES
If $ARGUMENTS is:
- "check" or "health" → Run Phase 1 only (health check)
- "refresh" → Run Phase 1, then for any EXPIRED keys, re-open signup page
- "add " → Skip to that specific provider in Phase 2
- "discover" → Run Phase 6 (web search for new providers), then offer to provision
- "list" → Show the provider registry as a formatted table
- empty or "all" → Run full pipeline (Phases 1-5, skip Phase 6)
============================================================
============================================================
SELF-HEALING VALIDATION (max 2 iterations)
After completing deployment/infrastructure changes, validate:
- Verify all generated files are syntactically valid (YAML, JSON, HCL, Dockerfile).
- Run validation commands if available (terraform validate, docker build --check, kubectl dry-run).
- Verify no secrets, credentials, or sensitive values are hardcoded.
- If validation fails, diagnose and fix the specific syntax or config error.
- Repeat up to 2 iterations.
IF STILL FAILING after 2 iterations:
- Document what failed and the exact error
- Include partial output if available
============================================================
SELF-EVOLUTION TELEMETRY
After producing output, record execution metadata for the /evolve pipeline.
Check if a project memory directory exists:
- Look for the project path in
~/.claude/projects/
- If found, append to
skill-telemetry.md in that memory directory
Entry format:
### /free-keys — {{YYYY-MM-DD}}
- Outcome: {{SUCCESS | PARTIAL | FAILED}}
- Self-healed: {{yes — what was healed | no}}
- Iterations used: {{N}} / {{N max}}
- Bottleneck: {{phase that struggled or "none"}}
- Suggestion: {{one-line improvement idea for /evolve, or "none"}}
Only log if the memory directory exists. Skip silently if not found.
Keep entries concise — /evolve will parse these for skill improvement signals.
STRICT RULES
- NEVER create accounts programmatically or attempt to bypass CAPTCHAs
- NEVER store API keys anywhere except the configured env file(s)
- ALWAYS validate a key before saving it
- ALWAYS make a backup-friendly edit (use Edit tool, not full file rewrites)
- When updating YAML configs, preserve existing entries — only ADD new ones
- When updating JSON configs, use jq or careful Edit — do not corrupt the file
- Sort free-forever providers first in all output
- Set rpm/tpm limits on every new LiteLLM deployment for proper load balancing
- The goal is maximizing free LLM capacity across all providers
