opencode-analyzer

OpenCode cost analyzer with detailed daily/weekly/monthly breakdowns. Shows what you actually spent vs what it would cost on OpenRouter, plus same-token model comparisons.

What It Does

Queries your local OpenCode SQLite database to show:

• Daily, weekly, and monthly spending
• Average costs per day/week/month
• Cost projections
• Top models by spending
• OpenRouter cost equivalents for free models
• Same-token repricing across comparable model tiers

Installation

# Copy to your skills directory
cp -r skills/opencode-analyzer ~/.config/opencode/skills/

# Or create symlink to command
ln -s ~/.config/opencode/skills/opencode-analyzer/opencode-cost ~/.local/bin/opencode-cost

Optional plugin sources are stored in skills/opencode-analyzer/plugins/.

Plugin behavior (optional)

When enabled in a compatible OpenCode runtime, the plugin layer is intended to:

• Surface quick spend context inside OpenCode (today, yesterday, 7d, 30d)
• Use actual costs for paid usage and OpenRouter estimates for free-model usage
• Show rolling averages and a short top-model cost list

If your runtime does not expose plugin sidebar UI, use the command path (opencode-cost and /cost-report), which is the primary supported workflow for this skill.

Sections Explained

📅 Spending by Period

• Today: Current day's spending
• Yesterday: Previous day's spending
• Last 7 Days: Week total
• Last 30 Days: Month total
• All Time: Complete history

📊 Averages

• Daily/Weekly/Monthly (30d): Rolling averages based on the last 30 calendar days
• Daily Avg (active): Average per active day across all-time usage

🔮 Projection

• Projected (7d run-rate): Based on last 7 days active-day run rate × 30

🧪 Model Comparison (Same 7d Tokens)

• Uses your exact last 7 days input/output token totals
• Pulls current trending models from OpenRouter rankings
• Reprices those same tokens across comparable model tiers
• Shows 7-day repriced cost and 30-day run-rate per model
• Helps compare options without changing usage volume

☁️ AWS vs OpenRouter (30d from 7d usage)

• Uses your exact last 7 days tokens and projects to 30 days
• Compares AWS us-east on-demand rates vs OpenRouter model rates
• Includes Claude Sonnet/Opus 4.6 (and Long Context on AWS), DeepSeek, Kimi, GLM, Qwen, and Minimax
• Rounds displayed values up to the nearest cent for budget planning
• Adds ZDR column (whether model has at least one OpenRouter ZDR endpoint)
• Adds MM column (whether the model supports non-text inputs)

📈 Activity

• Active days plus total calendar span since first usage

🔥 Top Models

• Most expensive models (by cost, not tokens)
• Shows cost and percentage of monthly total

Cost Calculation

Paid models: Uses actual cost from OpenCode
Free models: Uses OpenRouter pricing:

Model	Input	Output
GLM 4.6	$0.30/M	$2.55/M
Kimi K2.5	$0.50/M	$2.40/M
Gemini 2.5 Flash	$0.30/M	$2.50/M
GPT-5.3 Codex	$1.25/M	$10.00/M
MiniMax M2.5	$0.15/M	$0.60/M
Claude Opus	$5.00/M	$25.00/M
Qwen	$0.40/M	$2.40/M

Comparison table dynamically selects current OpenRouter trending models in value, balanced, and premium classes. If live fetch fails, it falls back to a stable default set.

Database Location

Auto-detects from:

• ~/.local/share/opencode/opencode.db (default)
• ~/Library/Application Support/opencode/opencode.db (macOS)

Requirements

• sqlite3 (usually pre-installed)
• bc (for calculations, usually pre-installed)

Examples

# Default breakdown
opencode-cost

# Use specific database
opencode-cost --db /path/to/opencode.db

Troubleshooting

Database not found

# Find your database
find ~ -name "opencode.db" 2>/dev/null

# Specify path
opencode-cost --db /path/to/opencode.db

Permission denied

chmod 644 ~/.local/share/opencode/opencode.db

sqlite3 not found

# macOS
brew install sqlite

# Ubuntu/Debian
sudo apt-get install sqlite3

Notes

• Negative values (refunds/adjustments) are excluded
• Free models show OpenRouter equivalent cost
• Projections based on recent 7-day average
• Only counts days you actually used OpenCode
