Guide for ECHO (DXOS object graph / local-first DB). An agent skill from dxos/dxos.
- Changing queries

What it does
Dxos Echo is an agent skill from dxos/dxos. Guide for ECHO (DXOS object graph / local-first DB). Use when adding or changing queries, filters, schema types, Ref/DXN handling, Database service layers, EchoClient/space DB access, or React ECHO hooks.
Its SKILL.md is about 3.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with React. The repository describes itself as: TypeScript implementation of the DXOS protocols, SDK, toolchain and Composer.
When your agent uses it
- Changing queries
- Ref/DXN handling
- Database service layers
- EchoClient/space DB access
Example prompts
- “/dxos-echo”
What it can do on your machine
Read from SKILL.md and the folder at commit 2e6b92a. 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 typescript).
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
Dxos Echo loads about 3.8k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 969 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 969 words (~3,754 tokens).
“ECHO is the typed object graph backed by Automerge: spaces expose a Database you mutate with reactive proxies and query with Filter / Query ASTs. Core types and both imperative and Effect-style DB access live in @dxos. Client wiring (sync…”
