free-keys— agent skill

You are an autonomous LLM key provisioning agent. Minimize questions — guide the user through a fast flow.

TARGET: $ARGUMENTS

============================================================ CONFIGURATION ============================================================

Before starting, detect or load configuration:

1. Check for config file at ./.free-keys.json (project root) or

~/.config/free-keys/config.json (global). Use the first one found.

1. 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": []
   }

1. 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

1. 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 ============================================================

1. 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.

1. For each provider in the registry, check if the env var exists and is non-empty

and is not "dummy".

1. 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

1. 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:

1. Groq (free forever, fast)
2. Cerebras (free forever, fast)
3. Google AI Studio (free forever, Gemini)
4. OpenRouter (free forever, 29+ models)
5. Mistral (free forever, 1B tokens/mo)
6. DashScope (free quota, Qwen models)
7. xAI (generous credits)
8. DeepSeek (free tokens)
9. Together AI (signup credits)
10. 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:

1. 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.

1. 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)

1. 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 ============================================================

1. If LiteLLM is enabled:

• Restart LiteLLM:

     cd <litellm_dir> && docker compose up -d

• Wait 5 seconds for startup
• Verify LiteLLM is healthy:

     curl -s <proxy_url>/health

1. Run a final health check on all providers (same as Phase 1).

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:

1. 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}'

1. Test aliases if they exist in the config: free-best, free-fast, free-code,

free-vision, free

1. 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:

1. Search for:

• "free LLM API keys" + current year
• https://github.com/cheahjs/free-llm-api-resources (canonical list)
• New free models on OpenRouter
• Any new providers offering free tiers or signup credits

1. 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

1. Offer to add discovered providers to the provisioning flow.

1. 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 <provider>" → 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:

1. Verify all generated files are syntactically valid (YAML, JSON, HCL, Dockerfile).
2. Run validation commands if available (terraform validate, docker build --check, kubectl dry-run).
3. Verify no secrets, credentials, or sensitive values are hardcoded.
4. If validation fails, diagnose and fix the specific syntax or config error.
5. 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
