What is dt-dql-essentials?

A reference guide for DQL, the query language used to analyze data in Dynatrace. It explains syntax, common mistakes, data fields, topology navigation, aggregation, operators, and time-series handling.

Use it when creating or checking DQL queries, especially queries involving Dynatrace data fields, services and topology, summaries, time series, operators, or arrays.

DQL differs from SQL, so familiar query habits can produce errors. The guide provides the rules and patterns needed before writing queries.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00039	$0.06332
Opus 5	$0.00019	$0.03166
Sonnet 5	$0.00008	$0.01266
Haiku 4.5	$0.00004	$0.00633

Measured 11d ago against content hash 3be0ad4374c9, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

dt-dql-essentials 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 11d 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.

DQL Essentials Skill

This file is canonical for DQL syntax, pitfalls, and patterns. See governing briefing files (copilot-instructions.md/CLAUDE.md), CONVENTIONS.md (for workspace/temp rules, reconciliation, Sync Checklist), and references/dql/* for full agent rules. Load this skill FIRST before any DQL. Review all relevant workspace files (including temp_dtctl_files/**) first.

DQL is a pipeline-based query language. Queries chain commands with | to filter, transform, and aggregate data. DQL has unique syntax that differs from SQL — load this skill before writing any DQL query.

Changes

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.
