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.

Security

Grade A, and why

revibe scanned grade A with 1 finding 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 1mo ago.

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.

Revibe — Codebase Analysis

Analyze a codebase to understand its architecture, file roles, design patterns, execution flows, and system design decisions. Returns structured insights and saves agent_context.json for persistent codebase understanding.

Instructions

1. Determine the target

  • If $ARGUMENTS contains a GitHub URL or owner/repo shorthand, use that
  • If $ARGUMENTS is empty, detect from the current directory:
    git remote get-url origin 2>/dev/null
    
    Convert SSH to HTTPS if needed ([email protected]:owner/repo.git → https://github.com/owner/repo)
  • If not in a git repo and no URL provided, ask the user

2. Check for API key

The user needs a REVIBE_API_KEY environment variable. Check if it's set:

echo "${REVIBE_API_KEY:-not_set}"

If not set, tell the user:

You need a Revibe API key. Sign up free at https://app.revibe.codes, then go to Settings → API Keys to generate one. Then set it: export REVIBE_API_KEY=rk_live_your_key_here

3. Submit for analysis

curl -s -X POST "https://app-backend.revibe.codes/api/v1/analyze" \
  -H "Content-Type: application/json" \
  -H "X-Revibe-Key: ${REVIBE_API_KEY}" \
  -d "{\"github_url\": \"GITHUB_URL_HERE\"}"

If status is "completed", skip to step 5.

4. Poll for completion

If status is "processing", poll every 10 seconds (max 3 minutes):

curl -s "https://app-backend.revibe.codes/api/v1/analysis/${JOB_ID}/status" \
  -H "X-Revibe-Key: ${REVIBE_API_KEY}"

Show progress to the user as each step completes.

5. Show summary

Fetch the summary:

curl -s "https://app-backend.revibe.codes/api/v1/analysis/${JOB_ID}/summary" \
  -H "X-Revibe-Key: ${REVIBE_API_KEY}"

Display it as a formatted summary card:

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.
