What it does
Database Core is an agent skill from macro-inc/macro. Use when building a feature on reusable database storage or UI, such as CRM, or deciding whether it needs a Macro database entity. Covers storage and UI entry points, ownership, authorization, and the entities naming convention.
Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Sales & Support. The repository describes itself as: Macro is a unified workspace for teams: email, chat, docs, tasks, agents, calls, and CRM — @-linked together with shared AI memory. The licence is AGPL-3.0.
When your agent uses it
- Building a feature on reusable database storage
- Deciding whether it needs a Macro database entity
Example prompts
- “/database-core”
What it can do on your machine
Read from SKILL.md and the folder at commit 39f3c91. 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
Database Core loads about 645 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 290 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.

- description
- Use when building a feature on reusable database storage or UI, such as CRM, or deciding whether it needs a Macro database entity. Covers storage and UI entry points, ownership, authorization, and the _entities naming convention.
Database core
The database engine is a reusable resource. A feature can use its tables, columns, cells, versions, and journal with its own ownership, permissions, and lifecycle.
Choose the entry point
- Building a feature such as CRM: reference
databases.idfrom that feature's domain model. Use theDatabaseStorageport tocreate_storage,apply_storage_writes, anddelete_storage. - Working on the Macro database app: use
DatabasesService. Its repository creates the app entity and owner grant together;CellStoreenforces the entity's lifecycle during writes.
A new consumer authorizes access to its own resources, validates writes, and
controls discovery and cleanup. DatabaseStorage expects calls from a trusted
domain service; the composition root supplies its adapter. Creating core storage
requires no row in database_entities or database app grants and does not expose
it in Soup.
Keep product metadata on the entity
databases holds the core resource identity. An optional database_entities row
holds the Macro app's name, owner (user_id), lifecycle timestamps, and trash
state. Its database_id is both its primary key and a foreign key to the resource.
Use this pattern for new entities: a plural <kind>_entities table owns product
identity and lifecycle and references any reusable resource it uses. The naming
convention starts with databases; existing unrelated entity tables keep their names.
Rust type names stay singular.
Reuse the records UI
Use DatabaseRecordsView
with a host-provided DatabaseRowsSource, query/layout state, and action callbacks.
It needs no Macro database entity, saved-view metadata, or block context. Omit
schema actions when a feature allows record editing with a fixed schema.
The Macro app's DatabaseGrid supplies its API, Soup, and saved-view adapters;
other domains supply their own authorized reads, writes, and change notifications.
Read the storage boundary and domain ports before wiring a consumer. Follow the database guide for schema and migration work.
