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 | $0.01514 | $0.01514 |
| Opus 5 | $0.00757 | $0.00757 |
| Sonnet 5 | $0.00303 | $0.00303 |
| Haiku 4.5 | $0.00151 | $0.00151 |
Grade A, and why
claude-marketplace-sync CLAUDE.md scanned grade A with 0 findings 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 9d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview
Claude Code Marketplace Aggregator enables distributed, hierarchical composition of Claude Code marketplaces. The tool recursively syncs plugins from multiple child marketplaces into a parent marketplace, supporting denylisting and origin tracking.
Core concept: Each marketplace only manages its immediate children (declared in .sync-config.json), but through recursive application across multiple levels, this creates arbitrarily deep marketplace hierarchies.
Development Commands
Pre-Commit Workflow
IMPORTANT: Always run make before committing changes. This runs linting and all tests to ensure code quality.
# Run linting and all tests (do this before committing!)
make
Testing
# Run all tests (unit + functional)
make test
# Run only unit tests (fast, mocked git operations)
pytest tests/test_unit.py -v
# Run only functional tests (slower, real git operations)
pytest tests/test_functional.py -v
# Run a single test
pytest tests/test_unit.py::TestExtractRepoName::test_extract_repo_name_https_url -v
Linting and Formatting
# Check code formatting (pre-commit check)
make lint
# Equivalent: black --check --line-length 100 .
# Fix formatting issues automatically
make format
# Equivalent: black --line-length 100 .
# Note: If linting fails, run this to auto-fix formatting issues
Running the Script Locally
# Basic usage
python3 sync-marketplaces.py --config .sync-config.json --output .claude-plugin/marketplace.json
# With verbose logging
python3 sync-marketplaces.py --config examples/test-sync-config.json --verbose
Cleanup
make clean # Remove test artifacts and Python cache files
Code Architecture
Main Class: MarketplaceAggregator
Located in sync-marketplaces.py:25-347, this class orchestrates the entire sync process:
- Initialization (
__init__): Loads config, initializes tracking structures - Main Entry (
run): Creates temp directory, processes sources, generates outputs - Source Processing (
_process_source): Routes to marketplace or skill processing - Output Generation: Creates
marketplace.jsonandorigins.jsonfiles
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-marketplace-sync CLAUDE.md is an instructions file published in the GitHub repository ralphbean/claude-marketplace-sync (5 stars, last pushed 9mo ago), licensed MIT. It adds 1,514 tokens to every session, about $0.0076 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
