What it does
Observability is an agent skill from BuilderIO/agent-native. Agent observability, evals, feedback, and experiments. Use when adding observability dashboards, configuring trace capture, setting up evals, creating A/B experiments, or collecting user feedback on agent responses.
Its SKILL.md is about 7.3k 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 DevOps & Cloud, covering Observability and LLM evaluation. The repository describes itself as: A framework for building agentic apps.
When your agent uses it
- Adding observability dashboards
- Configuring trace capture
- Setting up evals
- Creating A/B experiments
Example prompts
- “/observability”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Traces
- Feedback
- Evals
- Experiments
- Dashboard
What it can do on your machine
Read from SKILL.md and the folder at commit be0d784. 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
Observability loads about 7.3k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 3,395 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 3,395 words (~7,289 tokens).
“The observability system auto-instruments every agent run with zero configuration. Traces, automated evals, and feedback collection work out of the box. All data lives in the app's own SQL database — no external services required. Templates can optionally export to…”
