claude-plugins-community is a read-only mirror of a marketplace listing community-contributed plugins for Claude Cowork and Claude Code. It is for discovering and installing plugins that extend those Claude products, while submissions are handled through Anthropic’s separate review process. Catalogue add-ons represent plugins, skills, and integrations associated with this marketplace.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00151 | $0.00538 |
| Opus 5 | $0.00076 | $0.00269 |
| Sonnet 5 | $0.00030 | $0.00108 |
| Haiku 4.5 | $0.00015 | $0.00054 |
Grade A, and why
tres-upload-tx-header-validation 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.
What it actually says
TRES CSV header naming convention
TRES validates the CSV header row against human-readable display names (with spaces and title case), NOT snake_case keys. Using the wrong names fails the upload with:
Missing required column(s): Year, Month, Day, Time, Organizational Wallet, Participating Wallet, Network, Direction, Financial Action, Asset Identifier, Amount, Fiat Currency, Transaction Hash, Transfer ID, Function Name, Method ID
The required header row (exact, in order)
Year,Month,Day,Time,Organizational Wallet,Participating Wallet,Network,Direction,Financial Action,Asset Identifier,Amount,Fiat Value,Fiat Currency,Transaction Hash,Transfer ID,Function Name,Method ID
Rules
- Use these names verbatim — exact spelling, spacing, and title case. They are the display names, not field keys.
- Keep the order above (columns A→Q).
Fiat Value(column L) is the one optional column — it does not appear in the "missing required column(s)" error, but include it in the header so the template stays aligned; its cells may be left blank.- All other 16 columns are required in the header row even if a given cell is empty.
Common mistake this prevents
Writing programmatic/snake_case headers like year,month,day,time,wallet_address,third_party,network,direction,type,asset_identifier,amount,fiat_value,fiat_currency,hash,transfer_id,function_name,method_id. These are rejected — TRES wants the display names above (e.g. Organizational Wallet not wallet_address, Participating Wallet not third_party, Financial Action not type, Transaction Hash not hash).
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.
