v0.2.0: Realistic TPS and Better Agent IDs

Improvements

Fixed

• Inflated TPS values — Changed denominator from to . This prevents 300+ TPS spikes when tokens arrive in bursts by accounting for idle time that naturally lowers the rate.
• Identical agent labels — All agents showed because OpenCode message IDs share the prefix. Now strips this prefix and shows 6 differentiating characters.

Changed

• Faster timing constants for more responsive feel:
  • : 250ms → 150ms (40% faster initial display)
  • : 500ms → 250ms (more responsive smoothing)
  • : 150ms → 80ms (nearly 2x faster UI updates)
  • : 0.1s → 0.3s (stable baseline)
• Reduced toast throttling — multiplier: 3x → 2x

Commits

• fix: correct TPS calculation to use elapsed time from oldest entry
• feat: improve TPS responsiveness with faster timing constants
• fix: improve agent ID display and reduce UI throttling
• docs: update README timing and bump version to 0.2.0

0.1.9

Full Changelog: v0.1.8...0.1.9

v0.1.8 - Agent Detection Improvements

Improvements

• Improved agent name detection from multiple sources
• Better handling of missing agent metadata
• Added debug logging for troubleshooting

Bug Fixes

• Fixed buildAgentLabel to handle missing type gracefully
• Improved getAllActiveAgentsGlobally to get agent name from cache when metadata is missing

v0.1.7 - Bug Fixes

Bug Fixes

• Agent name caching fixed - Previously the cache was never populated because info.agent is an AgentIdentity object (not a string). Now correctly extracts name from: agent.name > agent.type > agentType > agent.id
• Color coding in agent-only mode - Previously showed "slow" (red) because TPS was 0. Now uses max agent TPS for color determination
• formatAgentLine respects config - Now properly uses showInstant, showAverage, showTotalTokens settings instead of always showing all

Files Changed

• src/index.ts - Fixed agent name extraction from AgentIdentity object
• src/ui.ts - Fixed color coding logic and formatAgentLine config respect

v0.1.6 - Multi-agent TPS Tracking

What's New

Multi-Agent TPS Tracking

• Per-agent display: Each background agent (explore, librarian, etc.) now shows its own TPS instead of combined values
• Agent name caching: Uses info.agent from message.updated events for proper labels
• Explicit primary session: Stores primarySessionId instead of iteration-based detection
• Show/hide logic: Main TPS line hidden when only background agents are active

TPS Spike Prevention

• 3-level burst smoothing:
  • Normal streaming: 500ms half-life
  • Medium bursts (50-200 tokens): 3000ms half-life
  • Large bursts (200+ tokens): 5000ms half-life
• Initial TPS cap: Max 100 TPS on first reading to prevent startup spikes

UI Improvements

• Shorter IDs: Reduced from 8 to 4 characters for more compact display
• Timer-based fallback: Shows TPS after 250ms even if stream pauses

Testing

• Added 33 comprehensive tests for multi-agent scenarios
• All tests passing

Installation

npm install opencode-tps-meter@0.1.6

Or in OpenCode config:

{
  "plugins": ["opencode-tps-meter@0.1.6"]
}

v0.1.5 - EWMA Smoothing for TPS Spike Prevention

What's New

Features

• EWMA Smoothing: Added Exponentially Weighted Moving Average (EWMA) smoothing to prevent unrealistic TPS spikes from bursty token arrivals (e.g., tool outputs)
• Adaptive Half-Life: Normal streaming uses 500ms half-life, bursts (>120 tokens) use 2000ms for stronger smoothing
• New method: Returns EWMA-smoothed TPS values for more stable UI display

Bug Fixes

• Fixed buffer pruning bug: When all entries were expired, returned -1 and nothing was removed - now properly clears the buffer
• Renamed misleading variable: → to accurately reflect the smoothed value

Technical Details

• Added constants: (120), (500), (2000)
• Buffer pruning now uses in-place mutation () instead of reassignment
• Enhanced test coverage for burst smoothing scenarios

Breaking Changes

None - the plugin now displays smoothed TPS by default, providing more accurate and stable metrics.

Testing

• All 28 tests pass
• Build successful (ESM + CJS + TypeScript declarations)
• Verified smoothing behavior with large token bursts

v0.1.4 - CJS/ESM Compatibility Fix

Fixes

• CJS Export Timing: Move module.exports to end of file to ensure TpsMeterPlugin function is defined before export
• ESM Compatibility: Add module.exports.default and __esModule flag for proper ESM/CJS interop
• dist/package.json: Create separate package.json in dist folder with type:commonjs to fix Node.js loading

This resolves the 'fn3 is not a function' error when loading the plugin in OpenCode.

v0.1.3 - Fix CJS Export

Fixed: Plugin function was being called during module load instead of being exported

v0.1.2 - Config Fix

Fix config undefined error

v0.1.1 - Bug Fix Release

🐛 Bug Fix Release v0.1.1
