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 | $0.00179 | $0.02605 |
| Opus 5 | $0.00089 | $0.01303 |
| Sonnet 5 | $0.00036 | $0.00521 |
| Haiku 4.5 | $0.00018 | $0.00261 |
Grade A, and why
tres-recon-gaps 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 11d 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.

TRES Reconciliation Gaps Skill
End-to-end workflow for surfacing, analyzing, and resolving reconciliation gaps in TRES Finance.
Pre-flight: confirm date and asset scope
Before fetching any data, confirm two things with the user:
1. Target date
The reconciliation queries are scoped to a specific date (the endDate parameter).
- If the user explicitly stated a date — use it.
- If the user did not mention a date — assume today's date and inform them:
"I'll fetch reconciliation gaps for today (YYYY-MM-DD). Let me know if you want a different date."
Use ISO format YYYY-MM-DD throughout.
2. Asset filter (optional)
- If the user named specific assets (e.g. "for ETH and USDC", "just BTC") — note them. After fetching, filter the results to only those
asset.symbolvalues before displaying. - If the user did not specify assets — fetch and display all gaps.
Step 1 — Fetch reconciliation gaps
Use the reconciliation query. Always pass the confirmed endDate. Fetch up to 200 at a time.
query GetReconciliationGaps($limit: Int, $offset: Int, $endDate: Date) {
reconciliation(limit: $limit, offset: $offset, endDate: $endDate) {
totalCount
results {
id
amount
calculatedBalance
state
status
gap
belongsTo {
id
name
identifier
}
asset {
key
identifier
symbol
platform
}
pendingTransactionsCount
pendingTransactionsTotalAmount
}
}
}
Variables: {"limit": 200, "offset": 0, "endDate": "<confirmed-date>"}
Note:
gap=calculatedBalance − historicalBalance. Positive means the ledger has more than on-chain; negative means the ledger has less.
If the user requested specific assets, filter the results now: keep only rows where asset.symbol matches the requested symbols (case-insensitive).
Step 2 — Enrich with fiat values and on-chain balances
Take all IDs from the (filtered) Step 1 results and query assetBalance:
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

tres-recon-gaps is a skill published in the GitHub repository anthropics/claude-plugins-community (3,734 stars, last pushed 16d ago), licensed Apache-2.0. It adds 179 tokens to every session and 2,605 once invoked, about $0.0009 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.
