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.

Model	Per session	Once invoked
Fable 5.1	$0.01084	$0.01084
Opus 5.5	$0.00434	$0.00434

Security

Grade B, and why

claude-hud-glm CLAUDE.md scanned grade B 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 2mo 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Project Overview

Claude HUD is a Claude Code plugin that displays a real-time multi-line statusline. It shows context health, tool activity, agent status, and todo progress.

Build Commands

npm ci               # Install dependencies
npm run build        # Build TypeScript to dist/

# Test with sample stdin data
echo '{"model":{"display_name":"Opus"},"context_window":{"current_usage":{"input_tokens":45000},"context_window_size":200000}}' | node dist/index.js

Architecture

Data Flow

Claude Code → stdin JSON → parse → render lines → stdout → Claude Code displays
           ↘ transcript_path → parse JSONL → tools/agents/todos

Key insight: The statusline is invoked every ~300ms by Claude Code. Each invocation:

Receives JSON via stdin (model, context, tokens - native accurate data)
Parses the transcript JSONL file for tools, agents, and todos
Renders multi-line output to stdout
Claude Code displays all lines

Data Sources

Native from stdin JSON (accurate, no estimation):

model.display_name - Current model
context_window.current_usage - Token counts
context_window.context_window_size - Max context
transcript_path - Path to session transcript

From transcript JSONL parsing:

tool_use blocks → tool name, input, start time
tool_result blocks → completion, duration
Running tools = tool_use without matching tool_result
TodoWrite calls → todo list
Task calls → agent info

From config files:

MCP count from ~/.claude/settings.json (mcpServers)
Hooks count from ~/.claude/settings.json (hooks)
Rules count from CLAUDE.md files

From OAuth credentials (~/.claude/.credentials.json, when display.showUsage enabled):

claudeAiOauth.accessToken - OAuth token for API calls
claudeAiOauth.subscriptionType - User's plan (Pro, Max, Team)

From Anthropic Usage API (api.anthropic.com/api/oauth/usage):

5-hour and 7-day usage percentages
Reset timestamps (cached 60s success, 15s failure)

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.

claude-hud-glm CLAUDE.md is an instructions file published in the GitHub repository Siiichenggg/claude-hud-glm (5 stars, last pushed 9mo ago), licensed MIT. It adds 1,084 tokens to every session, about $0.0043 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
