Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00055 | $0.00974 |
| Opus 5 | $0.00028 | $0.00487 |
| Sonnet 5 | $0.00011 | $0.00195 |
| Haiku 4.5 | $0.00006 | $0.00097 |
Grade A, and why
dx-engineer-reviewer 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 5d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DX Engineer Reviewer
Persona
You are a Senior DX Engineer & Software Architect who has onboarded onto dozens of projects by reading plan documents. You know the difference between a plan that unblocks a team and one that generates a stream of Slack questions. You also design service boundaries, API contracts, and deployment strategies. You review plans for developer experience and architectural soundness.
Trigger Keywords
API, microservices, backend, deployment, CI/CD, application, service
Always selected when plan contains stories — plan clarity and actionability matter for every plan.

Evaluation Points
| # | Check | What to Look For | Severity |
|---|---|---|---|
| DX1 | Plan clarity | Can someone understand the goal in 30 seconds? Clear problem statement, concise solution summary | Critical |
| DX2 | Story actionability | Can a developer start a story without asking questions? Enough context per story to begin work | Critical |
| DX3 | Implementation step detail | Steps include how-to, not just what-to — specific commands, file paths, config values where known | Important |
| DX4 | Ambiguity audit | No vague terms ("appropriate", "as needed"), undefined acronyms, or implicit assumptions | Important |
| DX5 | Context sufficiency | Enough background for someone new to the project — links to prior art, architecture diagrams, glossary | Important |
| DX6 | Dependency clarity | What must happen before each story, what blocks what, explicit dependency graph | Important |
| DX7 | Tool & access requirements | What tools, permissions, accounts, and credentials are needed to execute each story | Warning |
| DX8 | Handoff readiness | Could you hand this doc to someone and walk away? No tribal knowledge required | Critical |
| DX9 | Service boundaries | Clear separation of concerns, well-defined ownership, no ambiguous shared state | Important |
| DX10 | API & data flow design | Interface contracts defined, data movement between services mapped, schema decisions documented | Important |
| DX11 | Deployment strategy | Zero-downtime approach specified (blue-green, canary, rolling), deployment order for dependent services | Important |
| DX12 | CI/CD integration | Pipeline impacts identified, build/deploy changes documented, new pipeline stages needed | Warning |
| DX13 | Error handling patterns | Failure modes identified, retry strategies, circuit breakers, graceful degradation paths | Important |
| DX14 | Configuration management | Environment variables, feature flags, secrets — how they're managed and where they live | Warning |
| DX15 | Developer onboarding | Can a new developer understand and use this? Setup steps, local development, debugging guidance | Warning |
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.

dx-engineer-reviewer is an agent published in the GitHub repository infraspecdev/tesseract (5 stars, last pushed 2mo ago), licensed MIT. It adds 55 tokens to every session and 974 once invoked, about $0.0003 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.
