compare

compare is a command for Claude Code from hoangsonww/Claude-Code-Agent-Monitor. It costs 12 tokens per session (477 once invoked), scanned A, original, MIT.

A command that compares two Claude Code sessions using their costs and workflow details.

In plain words
What is it for?
Use it when you have two session IDs and want a side-by-side report with metric changes between them.
Why use it?
It makes differences in spending, tokens, tools, agents, complexity, errors, and subagent results visible in one comparison.

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

compare 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 7d 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.

What it actually says

Compare the two sessions in $ARGUMENTS (first id = Session A, second id = Session B) side-by-side using the Agent Monitor dashboard. If fewer than two ids are given, ask for both.

  1. Fetch cost for each, in parallel:

    • curl -s http://localhost:4820/api/pricing/cost/<sessionA>
    • curl -s http://localhost:4820/api/pricing/cost/<sessionB> Each returns { total_cost, breakdown:[{ model, input_tokens, output_tokens, cache_read_tokens, cache_write_tokens, cost, matched_rule }] }.
  2. Fetch workflow intelligence for each:

    • curl -s http://localhost:4820/api/workflows/<sessionA>
    • curl -s http://localhost:4820/api/workflows/<sessionB> Use stats (tool/event/agent counts), complexity (score), effectiveness (subagent success), compaction (impact), and errorPropagation.
  3. Print a side-by-side comparison table with a delta column (B − A):

    • Total cost (USD, 4 decimals) and Δ% .
    • Tokens: input, output, cache_read, cache_write (sum the breakdown per session).
    • Cache hit rate = cache_read / (cache_read + input).
    • Tool count, event count, agent count (from stats).
    • Complexity score (from complexity).
    • Subagent success rate (from effectiveness) and compaction count (from compaction).

Output rules: one row per metric with columns Session A | Session B | Δ; use ▲ when B is higher and ▼ when lower; currency in USD to 4 decimals; rates as percentages to 2 decimals. End with a one-line verdict on which session was cheaper/leaner and the main driver. Cite only fields the API returned — never fabricate. If a session id is unknown or the dashboard is unreachable at http://localhost:4820, say so and tell the user to start it with npm start from the repo root.

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.

compare is a command published in the GitHub repository hoangsonww/Claude-Code-Agent-Monitor (989 stars, last pushed 2d ago), licensed MIT. It adds 12 tokens to every session and 477 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
