Service Specifications

This document details the operational scope, required client inputs, technical delivery standards, handoff formats, realistic turnaround times, and known edge-case constraints across the OKZGN service catalog. Every engagement is executed under strict software engineering principles: reproducible environments, deterministic delivery, and hardened infrastructure.

Standard Engagement Protocol

To avoid scope creep, technical friction, and operational bottlenecks, all projects follow an established four-stage intake and delivery lifecycle:

  • 1. Discovery & Technical Pre-flight: Before sending credentials, source code, or payments, consultation is conducted directly via official channels. Exact milestones are defined, system compatibility is verified, and mutual NDAs are executed if proprietary data is involved.
  • 2. Zero-Trust Access Provisioning: Root credentials, shared master passwords, or personal account tokens must never be transmitted over plain chat. Public SSH keys, GPG keys, or specific IAM permission scopes (least-privilege model) are provisioned for staging and production environments.
  • 3. Iterative Execution & Staging: Implementations are executed in isolated staging branches or dedicated sandboxes with verifiable benchmarks and reproducible build pipelines.
  • 4. Final Handoff & Knowledge Transfer: Production sign-off includes tagged Git repositories, infrastructure-as-code manifests, architecture documentation (Markdown), and direct handover support.

1. Applied Artificial Intelligence

Advanced Prompt Engineering

Scope of Work: Empirical optimization of system prompts, meta-instructions, context windows, and output guardrails to achieve deterministic structure, zero evasion, and high fidelity from foundation LLMs.

  • Required Client Inputs: Minimum 50–100 real-world input examples with desired ground-truth outputs, failure logs from existing prompts, and target LLM vendor/version constraints (OpenAI, Anthropic, Gemini, Llama).
  • Deliverables & Formats: Version-controlled prompt engineering suite (Markdown/YAML files), JSON Schema output definitions, automated eval test harness (Python/TypeScript), and precision benchmark report.
  • Contact Point: Schedule a technical intake call with the assistant to review edge cases and domain-specific terminology.
  • Estimated Timelines: 3 to 7 business days depending on dataset volume and heuristic complexity.
  • Caveats & Operational Constraints: Upstream foundation model updates by vendors may introduce minor behavioral drift; prompts are tuned against fixed model checkpoints to guarantee stability.

Autonomous Multimodal Agents

Scope of Work: Engineering autonomous task-oriented agents capable of parsing text, PDFs, audio, and visual data, equipped with secure external tool invocation (APIs, databases, headless web browsers).

  • Required Client Inputs: End-to-end procedural workflow map, sandboxed API credentials for all external tools the agent must invoke, explicit boundary conditions (what the agent is strictly prohibited from doing), and communication channels (WhatsApp, Slack, Webhooks).
  • Deliverables & Formats: Full agent application source code (Node.js, Python, or Go), containerized deployment setup (Docker), persistent conversational memory layer, and real-time execution audit logs.
  • Contact Point: Technical consultation with the assistant to specify state-machine states and fallback routing before writing agent runtime code.
  • Estimated Timelines: Simple single-tool agents: 5–10 business days. Complex multi-step, multi-agent swarms: 3–6 weeks.
