What it does
Mz Adapter Guide is an agent skill from MaterializeInc/materialize. Correctness invariants + architecture: adapter, coordinator, pgwire, peek paths, timestamp oracle. Trigger: questions about these subsystems — "how does coordinator work", "what are read holds", "explain peek path", "how does timestamp selection work", "why does this query block". Also when editing OR reviewing code in src/adapter/, src/pgwire/, src/timestamp-oracle/ (reviewing a PR, diff, or commit that touches these paths counts).
Its SKILL.md is about 430 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. 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
- Databases work in your project
Example prompts
- “how does coordinator work”
- “what are read holds”
- “explain peek path”
- “/mz-adapter-guide”
What it can do on your machine
Read from SKILL.md and the folder at commit b760ecc. 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
Mz Adapter Guide loads about 432 tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 163 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 163 words (~432 tokens).
“When working on or reviewing the adapter layer or related crates, always read and follow the guidance in doc/developer/guide-adapter.md. That document contains correctness invariants, architectural notes, a list of optimizations that have been tried and rejected for correctness reasons, and…”
