What it does

Cluster Operations is an agent skill from chmonitor/chmonitor. Cluster management: distributed tables, ON CLUSTER DDL, node lifecycle, resharding, load balancing, and Keeper migration.

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Container orchestration, Cloud networking and Data warehousing. It works with ClickHouse. The repository describes itself as: Open-source operational advisor for ClickHouse — real-time monitoring plus AI-driven index/partition/materialized-view recommendations. The licence is GPL-3.0.

When your agent uses it

Example prompts

“/cluster-operations”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Install ClickHouse on new node
Configure Keeper/ZooKeeper connection
Update cluster config (remote_servers) on all nodes
Create local tables on new node
ReplicatedMergeTree: data syncs automatically; non-replicated: copy or re-insert

What it can do on your machine

Read from SKILL.md and the folder at commit fc39ef0. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cluster Operations loads about 634 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 278 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~35
When it runs · the whole SKILL.md, loaded when a task matches: ~634

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Cluster management: distributed tables, ON CLUSTER DDL, node lifecycle, resharding, load balancing, and Keeper migration.

Cluster Operations

Distributed Tables

CREATE TABLE dist ENGINE = Distributed(cluster, db, local_table, sharding_key)
Sharding key: rand() for even distribution, cityHash64(user_id) for user affinity
Reads: query all shards in parallel; Writes: route to correct shard or write locally

ON CLUSTER DDL

ALTER TABLE t ON CLUSTER '{cluster}' ADD COLUMN col Type — propagate schema to all replicas
CREATE TABLE t ON CLUSTER '{cluster}' AS template_db.template_table — clone across shards
distributed_ddl_output_mode: throw (fail on error), null (ignore), none, active
Check status: SELECT * FROM system.distributed_ddl_queue

Load Balancing and Read Routing

load_balancing: random, in_order, first_or_random, nearest_hostname
max_replica_delay_for_distributed_queries — skip lagging replicas
fallback_to_stale_replicas_for_distributed_queries=1 — use stale when all delayed

Adding Nodes

Install ClickHouse on new node
Configure Keeper/ZooKeeper connection
Update cluster config (remote_servers) on all nodes
Create local tables on new node
ReplicatedMergeTree: data syncs automatically; non-replicated: copy or re-insert

Removing Nodes

Stop writes, wait for replication queue to drain
SYSTEM DROP REPLICA for replicated tables
Remove from cluster config, restart remaining nodes

Resharding

No native online resharding — create new distributed table with new sharding scheme
INSERT INTO new_dist SELECT * FROM old_dist or clickhouse-copier for large migrations

Cluster Recovery

SYSTEM RESTART REPLICA ON CLUSTER '{cluster}' — restart replication across all nodes
SYSTEM SYNC REPLICA ON CLUSTER '{cluster}' — force sync from ZooKeeper
SYSTEM FETCH PARTS ON CLUSTER '{cluster}' — pull missing parts from other replicas

Monitoring Clusters

system.clusters — topology; system.distributed_ddl_queue — DDL status; system.replicas — replication
Cross-shard queries: use Distributed table or remote() function

Keeper Migration (ZooKeeper to ClickHouse Keeper)

Deploy ClickHouse Keeper alongside ZooKeeper
Snapshot data: clickhouse-keeper-converter or zk-dump.sh
Configure Keeper with converted snapshot
Update zookeeper config, restart one node at a time
Verify replication recovers, then remove ZooKeeper
