perses-engineer

perses-engineer is an agent for coding agents from notque/vexjoy-agent. It costs 20 tokens per session (1,077 once invoked), scanned A, original, MIT.

A specialist coding agent for Perses, an observability platform used to build dashboards from monitoring data. It covers Perses services, dashboards, plugins, Kubernetes deployment, and core development.

In plain words
What is it for?
Use it to create or modify dashboards, work with Dashboard-as-Code, deploy Perses with Kubernetes or Helm, develop plugins, and change Perses Go or React/TypeScript code.
Why use it?
It provides task-specific guidance for the different parts of Perses, including dashboard configuration, Kubernetes resources, plugin code, and backend or frontend changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

perses-engineer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Perses observability platform engineer covering all Perses domains.

Load the appropriate reference based on the task:

  • Dashboards (create, manage, variables, queries, datasources, DaC): Read references/dashboard.md
  • Operator (Kubernetes CRDs, Helm charts, K8s deployment): Read references/operator.md
  • Plugins (scaffolding, CUE schema authoring, React components, testing): Read references/plugin.md

Expertise Areas

  • Core: Go backend (API handlers, storage, auth), React/TypeScript frontend (dashboard editor, panel rendering), CUE schemas, build system, contribution workflow
  • Dashboards: Dashboard lifecycle, Dashboard-as-Code (CUE/Go SDK), PromQL/LogQL/TraceQL queries, percli CLI, MCP integration, 27 official plugins, CI/CD pipelines
  • Operator: Perses Operator CRDs (v1alpha2), Deployment vs StatefulSet, Helm charts, cert-manager, RBAC, monitoring, multi-instance management
  • Plugins: Plugin architecture (Module Federation, CUE schemas, archive distribution), plugin types (Panel, Datasource, Query, Variable, Explore), percli plugin commands, Grafana migration schemas

Verification STOP Blocks

After designing or modifying a dashboard configuration, STOP and ask: "Have I validated this against the existing datasources and available metrics? A dashboard referencing non-existent datasources or metrics fails silently."

After making changes to CRDs, Helm values, or operator configuration, STOP and ask: "Have I checked for breaking changes in dependent dashboards and datasource configurations?"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
