pisama-claude-code

Lightweight trace capture for Claude Code sessions with token usage and cost tracking.

Demo

Why Pisama?

When working with Claude Code, have you ever wondered:

• How much did that session cost? Track token usage and costs in real-time
• What tools were called? See every Bash, Read, Write, and Edit operation
• Why did it fail? Capture traces for debugging and forensics
• Can I export my sessions? JSONL export for analysis or compliance

pisama-claude-code captures everything Claude Code does, locally and privately.

Installation

pip install pisama-claude-code

Requirements: Python 3.10+ and Claude Code CLI

Quick Start

# 1. Install capture hooks
pisama-cc install

# 2. Use Claude Code normally - traces are captured automatically

# 3. View your session data
pisama-cc status        # Summary with token totals and cost
pisama-cc traces        # Recent tool calls
pisama-cc usage         # Detailed breakdown

Features

Token & Cost Tracking

$ pisama-cc usage --by-model --by-tool

📊 Token Usage Summary (last 100 traces)
==================================================
Input tokens:           10,234
Output tokens:          85,421
Cache read tokens:   1,234,567
Total cost:        $    52.34

📈 By Model:
--------------------------------------------------
  claude-opus-4-5-20251101            $52.34

🔧 By Tool:
--------------------------------------------------
  Bash                   45 calls  $25.12
  Read                   30 calls  $15.34
  Write                  20 calls  $8.45

Session Status

$ pisama-cc status

📊 Pisama Status
========================================

🔧 Hook Installation:
   ✅ pisama-capture.py
   ✅ pisama-pre.sh
   ✅ pisama-post.sh
   All hooks installed

📁 Local Traces: 1,400
   Input tokens:  9,580
   Output tokens: 79,569
   Total cost:    $43.22

Export & Analysis

# Export to JSONL
pisama-cc export -o traces.jsonl

# Export compressed
pisama-cc export -o traces.jsonl.gz --compress

# Export to OpenTelemetry format
pisama-cc export --format otel -o traces-otel.json

# Filter by date range
pisama-cc traces --since 2025-01-01 --until 2025-01-04

OpenTelemetry Integration

Export traces to any OTEL-compatible backend (Jaeger, Honeycomb, Datadog, etc.):

# Install OTEL support
pip install pisama-claude-code[otel]

# Export to local Jaeger
pisama-cc export-otel -e http://localhost:4318/v1/traces

# Export to Honeycomb
pisama-cc export-otel -e https://api.honeycomb.io/v1/traces \
    -H "x-honeycomb-team=YOUR_API_KEY"

# Export to file in OTEL format
pisama-cc export --format otel -o traces.json

OTEL export uses GenAI semantic conventions for token usage, costs, and model attributes.

Supported models and pricing (per 1M tokens):

Privacy & Security

• Local-first: all traces are stored in ~/.claude/pisama/traces/.
• Forwarding is opt-in: connect defaults to no auto-sync. Nothing leaves your machine until you run pisama-cc sync or reconnect with --auto-sync.
• Secrets scrubbed by default: credential-shaped strings (API keys, JWTs, cloud tokens) are redacted from content before forwarding — no extras needed. The optional [core] extra adds pisama-core's reversible keychain vault.
• Paths anonymized: home-directory paths are replaced with ~.
• Reasoning proxy is experimental + opt-in: pisama-cc proxy routes API traffic through a local logging proxy to recover extended-thinking. It defaults to API-key usage. Subscription (OAuth) users: it handles your account token, which is ToS-sensitive — use only knowingly.

See SECURITY.md for our security policy.

Configuration

After installation, the hooks are automatically configured. To customize, edit ~/.claude/settings.local.json:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "*",
        "hooks": [
          { "type": "command", "command": "~/.claude/hooks/pisama-post.sh", "timeout": 10, "async": true }
        ]
      }
    ],
    "Stop": [
      {
        "matcher": "*",
        "hooks": [
          { "type": "command", "command": "~/.claude/hooks/pisama-forward.sh", "timeout": 30, "async": true }
        ]
      }
    ]
  }
}

Platform Integration (Optional)

For advanced features like failure detection and self-healing, connect to the Pisama platform:

pisama-cc connect        # Authenticate
pisama-cc sync           # Upload traces
pisama-cc analyze        # Run detection

Platform features:

• 25 MAST failure mode detection
• AI-powered fix suggestions
• Self-healing automation
• Visual dashboard

Part of the Pisama Platform

pisama-claude-code is the Claude Code integration for the broader Pisama multi-agent failure detection platform, which supports multiple agent frameworks:

For other frameworks, see the mao-testing SDK.
