Enforce Domain Vocabulary for Coding Agents with Checks
A developer documents moving from prose instructions to mechanical checks to keep an agent-written codebase consistent. After writing domain-language rules (April 24) and a script to validate them (May 2), the first run flagged 737 terminology violations across roughly 150,000 lines of agent-generated code. The author argues that prose in prompts or a glossary is a soft preference, not a constraint, and that deterministic checks (linting scripts, pre-commit hooks and gates) are required to fail fast on vocabulary drift. The essay links this practice to Domain-Driven Design's ubiquitous language, recommends shifting measurable rules off probabilistic LLM behavior into formal checks, and presents a small case study — a Contact Center platform built with coding agents — showing practical limits and trade-offs of mechanical enforcement.
Practical developer guidance for tooling around LLM-driven code generation; useful for engineering teams adopting agentic workflows but not a platform-level or industry-shifting announcement.

Key Takeaways & Evidence Grounding
- Author wrote terminology rules as prose on 2026-04-24 and implemented a checking script on 2026-05-02.
- First run of the terminology check found 737 violations in approximately 150,000 lines of agent-written code.
- The terminology check scans multiple artifacts (Rust, markdown, config, protos, TypeScript frontend) for retired names and runs as pre-commit hooks.
- The project is a Contact Center platform built by directing coding agents; the author enforces the ubiquitous language end-to-end via mechanical gates.

Prose Control Plane: AI Agent Frameworks Aren't Engineering Yet
The article argues that popular AI agent skill frameworks rely on natural-language prose (Markdown instructions) as their behavioral control plane, which is inherently probabilistic and not deterministic engineering. It identifies three core failure modes—semantic drift, goal reinterpretation, and correlated verifier failure—where prose-based instructions and LLM verifiers can misinterpret goals or validate each other's mistakes. The author cites Anthropic guidance favoring simpler deterministic workflows over heavily scaffolded agentic systems and recommends deterministic guardrails for production use: compiled schema validation, type checking, independent test suites, immutable audit logs, and non-LLM verifiers. The conclusion: current skill frameworks are useful R&D tooling but insufficient as production engineering until deterministic enforcement is integrated as first-class components.
Loop Engineering: Fixing Misfiring Deterministic Guardrails
The article examines deterministic checks used as guardrails in iterative agent loops (generate, check, steer, retry, stop), showing how a simple grep-based check for 'import mock' produced a false positive by matching the phrase inside a docstring. It contrasts deterministic checks (repeatable, debuggable) with model-graded checks (flexible but less reliable) and argues that a misfire is evidence about the instrument, not the absence of the guarded condition. The author demonstrates fixing the grep by anchoring the pattern to start-of-line and recommends sharpening rules (or using linters) rather than deleting or weakening checks. The piece frames these practices as part of 'loop engineering' and deterministic diagnostics for prompts and instruction files.
Deterministic Guardrails for AI Agents
The article argues that LLM-powered agents with real-world tools pose high-risk failure modes (hallucinated package installs, prompt injection, insecure code commits, irreversible payments). A second LLM judge is insufficient because it can be socially engineered and adds latency/cost. Instead, the author advocates deterministic guardrails: narrow rule- or data-driven checks (e.g., package existence, prompt-injection detection, code-vulnerability scanning, payment screening) that return stable JSON verdicts (allow/review/block). The author provides examples of free guard APIs (package, content, code, payment) that use public data sources (OSV.dev, OFAC list, HIBP, DNS), and notes each guard is also available as an MCP server so MCP-aware agents can call them as tools. Recommended pattern: make guards mandatory pre-steps, treat 'block' as a hard stop and 'review' as human-in-the-loop.
