query-spec

A filtering language for selecting Control Plane resources by tags or properties and for sorting query results. It can be used in commands, APIs, policies, groups, and location settings.

In plain words
What is it for?
Filtering resource lists, targeting policy resources, assigning group members, selecting deployment locations, and querying resources through the CLI or API.
Why use it?
It lets selections update automatically as resources or labels change instead of maintaining fixed lists.

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

query-spec 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 2d 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.

Query Spec — Filtering & Selecting Resources

Control Plane has one query language used in two ways: ad-hoc filtering of a resource list (CLI / API), and dynamic targeting embedded inside three resource fields.

Where Field / command Purpose
Policy targetQuery Target resources by tag/property instead of listing targetLinks (see access-control)
Group memberQuery Assign members dynamically — users only
GVC spec.staticPlacement.locationQuery Select locations dynamically instead of listing locationLinks
CLI cpln KIND query Ad-hoc filtering — every resource kind
API POST /org/ORG/KIND/-query Ad-hoc filtering — every resource kind

Not an MCP list parameter. list_resources has no filter argument (list a kind, then filter the table yourself); query_audit_events filters by kind/name/subject/context/time; query_metrics takes PromQL. The query spec appears only inside the three resource fields above, set when you create or update that resource.

Structure

kind: workload          # resource kind being selected
fetch: items            # "items" (objects, default) or "links" (references)
spec:
  match: all            # "all" (default), "any", or "none"
  terms:
    - op: "="
      tag: environment
      value: production
    - op: exists
      tag: monitored
  sort:
    by: name
    order: asc

Terms

Each term targets exactly one of three fields (mutually exclusive — the schema rejects a term that sets more than one):

Field Targets Example
tag Resource tags (key/value labels) tag: environment, value: production
property Built-in properties (name, description, status.phase, …) property: name, value: my-app
rel Relationships to other resources rel: gvc, value: my-gvc

Operators

Operator Needs value Meaning
= yes Equal (default when op is omitted)
!= yes Not equal
> >= < <= yes Numeric / date comparison
~ yes Pattern match (schema op name match)
=~ yes Regex match (schema op name regex)
contains yes Substring match
exists no Tag/property is present (any value)
!exists no Tag/property is absent

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.

query-spec is a skill published in the GitHub repository controlplane-com/ai-plugin (10 stars, last pushed 8d ago), licensed MIT. It adds 48 tokens to every session and 1,631 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
