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 | $0.00068 | $0.00296 |
| Opus 5 | $0.00034 | $0.00148 |
| Sonnet 5 | $0.00014 | $0.00059 |
| Haiku 4.5 | $0.00007 | $0.00030 |
Grade A, and why
testdino-sessions 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
TestDino Exploratory Sessions
Use TestDino session tools when the user wants to browse, inspect, create, or update exploratory testing sessions.
Preferred flow:
- Call
healthifprojectIdis not known. - Use
list_sessionsto discover sessions by state, status, session type, assignee, release, or tags. - Use
get_sessionto inspect one session in detail. - Use
create_sessionorupdate_sessionfor session changes.
Important details:
sessionIdaccepts an internal ID or a counter-style ID likeSES-12.assigneeUserIdaccepts either a user ID or an email address.stateaccepts display form or canonical form, but canonical lowercase values are safest.tagsandlinkedIssuesmust be JSON arrays for create and update operations.
Good requests for this skill:
- list exploratory sessions in a project
- create an exploratory session for auth regression
- assign a session to [email protected]
- update session state to under review
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.

testdino-sessions is a skill published in the GitHub repository anthropics/claude-plugins-community (3,605 stars, last pushed 14d ago), licensed Apache-2.0. It adds 68 tokens to every session and 296 once invoked, about $0.0003 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 2026-08-30.
