- Tasks that involve Load testing

- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Mz Limits Test is an agent skill from MaterializeInc/materialize. Add/modify/debug limits test. Trigger: "limits test", "Generator subclass", "many objects", "scaling test", or stress-test Materialize with many objects (tables, views, sources, indexes). Also edits in test/limits/mzcompose.py.
Its SKILL.md is about 810 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 Databases, covering Load testing. It works with PostgreSQL. The repository describes itself as: The live data layer for apps and AI agents. Create up-to-the-second views into your business, just using SQL.
When your agent uses it
- Tasks that involve Load testing
Example prompts
- “limits test”
- “Generator subclass”
- “many objects”
- “/mz-limits-test”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Add a new class in test/limits/mzcompose.py that extends Generator.
- Implement the body() classmethod. It must print() testdrive commands.
- Optionally override COUNT and MAX_COUNT, only if it's causing issues in CI.
What it can do on your machine
Read from SKILL.md and the folder at commit 80f0437. 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 (its code samples are python).
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
Mz Limits Test loads about 808 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 169 words of instructions outside code blocks.
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 169 words (~808 tokens).
“The limits test stresses Materialize with large numbers of objects, complex queries, and large ingestions. It catches regressions via fixpoint panics, stack overflows, CI timeouts (O(N^M) with N~1000), and OOM panics (2GB memory limit).”
