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.

SkillSpector: 4 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Rogue Agent · line 193 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
- medium Data Exfiltration · line 67 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
- medium Data Exfiltration · line 119 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
- medium Agent Snooping · line 177 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00032 | $0.01490 |
| Opus 5 | $0.00016 | $0.00745 |
| Sonnet 5 | $0.00006 | $0.00298 |
| Haiku 4.5 | $0.00003 | $0.00149 |
Grade B, and why
clickhouse-cloud-management scanned grade B with 2 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 12d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

ClickHouse Cloud Management
ADR: 2025-12-08-clickhouse-cloud-management-skill
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
Overview
ClickHouse Cloud user and permission management via SQL commands over HTTP interface. This skill covers database user creation, permission grants, and credential management for ClickHouse Cloud instances.
Schema documentation principle: All ClickHouse table/column COMMENTs are the single source of truth (SSoT). When creating tables or columns, always include COMMENT clauses. See quality-tools:clickhouse-architect for the full COMMENT SSoT policy.
When to Use This Skill
Invoke this skill when:
- Creating database users for ClickHouse Cloud
- Managing user permissions (GRANT/REVOKE)
- Testing ClickHouse Cloud connectivity
- Troubleshooting authentication issues
- Understanding API key vs database user distinction
Key Concepts
Management Options
ClickHouse Cloud provides two management interfaces with different capabilities:
| Task | Via SQL (CLI/HTTP) | Via Cloud Console |
|---|---|---|
| Create database user | CREATE USER | Supported |
| Grant permissions | GRANT | Supported |
| Delete user | DROP USER | Supported |
| Create API key | Not possible | Only here |
Key distinction: Database users (created via SQL) authenticate to ClickHouse itself. API keys (created via console) authenticate to the ClickHouse Cloud management API.
Connection Details
ClickHouse Cloud exposes only HTTP interface publicly:
- Port: 443 (HTTPS)
- Protocol: HTTP (not native ClickHouse protocol)
- Native protocol: Requires AWS PrivateLink (not available without enterprise setup)
Password Requirements
What ships with it
2 files 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.

clickhouse-cloud-management is a skill published in the GitHub repository terrylica/cc-skills (73 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 1,490 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
