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 | $0.11662 | $0.11662 |
| Opus 5.5 | $0.04665 | $0.04665 |
| Sonnet 5.5 | $0.02332 | $0.02332 |
| Haiku 4.5 | $0.01166 | $0.01166 |
Grade A, and why
dtctl AGENTS.md 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 6d 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 — 822 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Agent Development Guide
kubectl-inspired CLI for Dynatrace (dashboards, workflows, SLOs, etc). Go + Cobra framework.
Pattern: dtctl <verb> <resource> [flags]
Quick Start
- Read docs/dev/API_DESIGN.md Design Principles (lines 17-110)
- Check IMPLEMENTATION_STATUS.md for feature matrix
- Copy patterns from

Architecture
cmd/ # Cobra commands (get, describe, create, delete, apply, exec, ctx, doctor, commands, plugin)
# plus the embedding entrypoint: run.go (cmd.Run + per-invocation isolation),
# session.go, capabilities.go, stdio.go, blocked.go (docs/dev/SERVICE_ENGINE_DESIGN.md)

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.

dtctl AGENTS.md is an instructions file published in the GitHub repository dynatrace-oss/dtctl (198 stars, last pushed yesterday), licensed Apache-2.0. It adds 11,662 tokens to every session, about $0.0466 per session on Opus 5.5. 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 2026-08-30.
