📰 What Happened

Agentic AI is starting to move beyond “writing code” into “executing work”

AWS has released Agent Plugins for AWS, which incorporates capabilities up to architecture design, cost estimation, Infrastructure as Code generation, and even deployment execution with tools like Claude Code and Cursor [8]. The idea is that when a user instructs the system—e.g., “Deploy this app to AWS”—it can proceed end-to-end: analyzing the codebase, proposing recommended configurations, looking up prices, generating configuration code, and performing the actual deployment [8].

  • This is more than just a chat helper; it signals that AI is beginning to cross the boundary between design → implementation → operations
  • By connecting AWS’s official knowledge, real-time pricing, and best practices, AWS is improving the accuracy and real-world applicability of agent decisions [8]
  • In development teams, AI is shifting from being “the person who writes code” to “the person who advances cloud configurations”

Terminal-first AI coding has evolved into something more practical for real work

Two introductory articles on Claude Code were published. They organize how to use it to understand an entire project from the terminal, edit multiple files across boundaries, and handle things like running tests and performing git operations [1][2]. It also emphasizes that if you make project policies and “no-edit” areas explicit in CLAUDE.md, you can stabilize how the AI behaves [1][2].

  • While GitHub Copilot is strong at in-IDE autocomplete, Claude Code is better suited for tasks that cycle through investigation, modification, and verification [1][2]
  • CLI workflows are a good fit for modifying multiple files, checking test results, and generating commit messages [1]
  • Real-world AI usage is shifting its weight away from “conversation” and toward “procedureization”

Corporate AI has made “connecting” and “protecting” into key themes

Google deployed a Gemini AI agent for dark web monitoring and published a system that analyzes event volumes on the order of millions per day to narrow down threats [11]. Meanwhile, NVIDIA demonstrated OpenShell, which runs autonomous AI agents in a sandbox and enforces constraints at the environment level—pursuing the direction of ensuring agent safety from the design stage [13].

  • Google’s move shows that AI is being deployed seriously for threat detection and investigation assistance [11]
  • NVIDIA’s move indicates that the more an agent touches multiple systems, the more runtime control becomes essential [13]
  • For enterprise adoption, not only AI performance but also access control, auditing, and isolation become prerequisites

The cloud market continues expanding as AI demand provides tailwinds

ITR predicts that Japan’s IaaS/PaaS cloud market will grow to about 244 billion yen in FY2026 and about 370 billion yen in FY2029 [15]. In particular, for PaaS, strengthening AI-related features is expected to drive adoption and upsells, while for IaaS, consolidation toward hyperscalers is expected to progress [15].

  • As AI adoption spreads, demand grows not only for model usage but also for underlying cloud infrastructure
  • When selecting cloud providers, differences won’t come from price alone; the depth of AI features will matter
  • Enterprise AI investment will broaden from adopting individual tools toward a holistic optimization across the foundation and operations

In the AI agent era, “what you can explain” becomes a competitive advantage

A guide was shared on how to build a multi-step AI agent in Node.js without any framework—highlighting the idea of assembling tools execution, memory management, and orchestration yourself [20]. At the same time, it again warns against shipping code generated by AI without understanding it [17].

  • In agent development, making behavior visible is starting to be valued over abstracted frameworks [20]
  • The more convenience increases, the heavier the human side’s review responsibility becomes [17]
  • Going forward, it won’t be “the people who can use AI” who win; it will be the people who can judge AI outputs

Evidence of execution and verifiability are becoming the next focal point

In NexArt’s explanation, “verifiable AI execution” and zkML are positioned as different: the former focuses on evidence of what was executed, while the latter focuses on proving that the computation is correct [21]. As AI adoption increases, there is a growing need to record not only results but also inputs, outputs, context, and tamper-resistance [21].

  • In scenarios that require auditability, accountability, and reproducibility, the authenticity of execution logs becomes important [21]
  • This has value not only in legal, finance, and regulated industries, but also in internal operations
  • AI is evolving from a “convenient suggestion engine” into a “business system that leaves evidence”

Implications moving forward

  • AI will expand from text generation and summarization into business execution, cloud operations, and security monitoring
  • The competitive axis will shift from model performance alone to connectivity, safety, and auditability
  • For enterprises, beyond adopting individual AI tools, a big-picture plan that includes access design and operations design will become crucial

🎯 How to Prepare

Shift from “testing” AI to “operating” it

For effective AI adoption, it’s not just about adding more convenient tools—it’s about deciding which business tasks to hand to AI and what humans must retain.

  • Keep key decisions with humans: limit AI’s role to drafts, comparisons, candidate generation, and first-pass investigation
  • Prioritize reproducibility: document project policies and constraints instead of relying on ad-hoc conversational context
  • Use the minimum necessary permissions: especially for data access, external transmission, and deployment execution—open permissions step by step
  • Prefer “traceable” over “fast”: automation that can’t be explained later becomes a long-term liability, even if it’s convenient in the short term

Identify which kinds of work are a good fit for AI

  • Work that fits well
    • Summarizing long texts and organizing key points
    • Initial reading of specifications, contracts, and meeting minutes
    • Finding candidate fixes for code and surfacing test angles
    • Drafting responses for routine inquiries
  • Work that does not fit well
    • Final judgments in legal, accounting, medical, and similar domains
    • Unlimited automated operations in production environments
    • Definitively answering with the latest information when source verification is required
    • Decisions where the truthfulness of data is strictly demanded

Priorities to keep in mind for real work in 2026

  1. Don’t take AI outputs at face value
  2. Standardize the flow of work
  3. Design permissions and auditing first
  4. Use tools differently for different purposes
  5. Start small, test, measure, then expand

Internal rules you should review right away

  • Clearly document information that must not be entered in your AI usage guidelines
  • Assign responsibility for reviewing generated outputs
  • Require approvals for high-impact operations such as deployment, deletion, and sending
  • Standardize saving outputs, capturing logs, and recording sources

How to approach it as a business professional

  • Instead of thinking “replace everything with AI,” adopt a mindset of reducing friction with AI
  • Not just improving individual productivity, but increasing the team’s reusability
  • Prioritize operations that won’t break later over just getting results quickly
  • Don’t stop AI adoption at PoC—define evaluation metrics and responsibility boundaries

🛠️ How to Use

Start by separating use cases and introduce them one by one

  • Claude: strong for long-text comprehension, specification organization, code fixes, and design review [2][5][14]
  • ChatGPT: easy to use for day-to-day work, idea support, and situations where you want an all-around balance [5][6]
  • Gemini: a strong option if you prioritize integrations with Google Workspace and search [5][6]
  • Claude Code: terminal-first, aimed at development workflows that involve editing multiple files and running tests [1][2]
  • Cursor / GitHub Copilot: effective if you want to strengthen in-IDE autocomplete and editing assistance [1][8]

How to try Claude Code starting today

  1. Launch it from the project root
  2. First, explain the technical stack, goals, and constraints
  3. Request work in the order of “investigate → propose a policy → implement → verify”
  4. Include instructions for test, lint, and typecheck
  5. Summarize operating rules in CLAUDE.md

Prompt examples

  • “Investigate this repository, identify the files that need changes, and provide 3修正 policy options. Then implement the safest option and run test and lint, summarizing the results.”
  • “Create a CLAUDE.md. Include forbidden areas, naming conventions, testing policy, and assumptions about review.”

Tips for running Claude Code as a team

  • Don’t write rules based on individual preferences—write team-wide rules in CLAUDE.md
  • Make it explicit before changes: “which parts are allowed to be touched”
  • After generation, always read the diff and have humans approve it
  • Automatically generating commit messages is convenient, but final confirmation must be done by people

AWS work is faster if you base it on Agent Plugins for AWS [8]

  • Before instructing Claude Code or Cursor to “Deploy this app to AWS,” decide in advance:
    • the existing architecture/configuration
    • which AWS services are allowed
    • monthly budget
    • areas that cannot be changed
  • Then, requests like the following get closer to real operations:
    • “Provide 3 AWS architecture proposals for this app”
    • “Estimate monthly costs conservatively”
    • “Generate this configuration with CDK”
    • “Point out any dangerous settings before deployment”

Use ChatGPT or Claude to streamline meetings and document processing

  • Paste meeting minutes and have it split them into “decisions,” “open items,” “owners,” and “deadlines”
  • Provide long documents and ask it to “compress this into three points from a management perspective”
  • Switch writing tone between “internal,” “customer-facing,” and “executive-facing”

Prompt examples

  • “Organize the following meeting notes into: 1) decisions 2) action items 3) risks 4) items to confirm by next time.”
  • “List unclear parts in this specification and create 10 confirmation questions.”

Expand external tool integration with MCP [3]

  • It’s easier to understand if you expand in Claude Desktop in this order: Filesystem → GitHub → Slack
  • Start with summarizing local materials
  • Next, move on to PR review assistance and turning Slack conversations into meeting notes
  • Finally, expand into investigations that span multiple tools

Good use cases

  • Read materials in local folders and extract key points
  • Read GitHub PR diffs and assist with review
  • Summarize Slack conversations and turn them into discussion points

Use APIs for long-running tasks or large-volume processing [4][9][10]

  • Use Claude API primarily with Messages API
  • Use streaming to improve perceived response speed
  • Design function calls via Tool Use
  • Receive structured output in JSON
  • If the same preamble is long, use Prompt Caching
  • For large batches, Batch API is a better fit

Implementation sketch

  • User input → Claude API
  • Call tools only when needed
  • Return results in JSON
  • Validate on the application side

Specific actions to try first

  • Pick one piece of writing work you repeat weekly in your job
  • Turn that into a Claude prompt
  • Create a one-page operational memo equivalent to CLAUDE.md
  • If you have AWS work, have AI output only the estimates first
  • If you write code, try coherent fixes across multiple files rather than changing just one file

⚠️ Risks & Guardrails

Risks to watch first, with the highest priority

1. Misinformation / hallucinations (Severity: High)

Claude and other LLMs can output incorrect facts in a natural writing style [7]. This is especially risky for topics like regulations, pricing, legal changes, incident reports, and security-related information.

  • Mitigations
    • Verify with official sources first
    • Let AI do only summarization
    • Explicitly state: “If it’s unknown, say it’s unknown”
    • Separate speculation from facts in the output

2. Over-automation with excessive permissions (Severity: High)

When agents touch deployment and configuration changes—such as with Agent Plugins for AWS—the impact of mistakes becomes larger [8]. NVIDIA OpenShell also highlights the need to control agent behavior at the environment level [13].

  • Mitigations
    • Start with the minimum permissions
    • Test in a staging environment before rolling changes into production
    • Require approvals for deletion, sending, and deployment
    • Enforce controls at runtime and don’t rely on prompts alone

Medium-level risks

3. Security leaks (Severity: High)

With MCP integrations and API integrations, there is a risk that tokens, internal materials, and customer information may flow outside [3][4].

  • Mitigations
    • Don’t input sensitive information
    • Limit the set of connection targets
    • Store tokens in environment variables and secret management
    • Keep access logs

4. Code not understood / becoming unmaintainable (Severity: High)

If you adopt AI-generated code without understanding it, you’re more likely to miss bugs and vulnerabilities [17][20].

  • Mitigations
    • Read changes diff-by-diff at the unit-of-work level
    • Don’t commit until you can explain the purpose and assumptions
    • Make tests, lint, and typecheck mandatory
    • Prefer making processing behavior visible over “framework magic”

5. Output variability / lack of reproducibility (Severity: Medium)

Quality can change dramatically depending on how you write prompts [12][16][18][19].

  • Mitigations
    • Fix roles, constraints, and formats
    • Use structured outputs like JSON
    • Compare multiple models for the same task
    • Template your prompts

Business-operational risks

6. Cost blow-up (Severity: Medium)

Long contexts and heavy API usage can increase costs more than they improve quality [4][16][18].

  • Mitigations
    • Provide only the necessary information
    • Combine summarization with search
    • Use models selectively by purpose
    • Estimate based on expected monthly usage volume

7. Copyright and IP risks (Severity: Medium)

If generated outputs are too similar to existing documents or code, they can create problems in public release or commercial use.

  • Mitigations
    • Don’t use outputs “as-is”—review them
    • Check citation sources and usage conditions
    • Set up internal rules for images, text, and code

8. Bias and overly confident automated decisions (Severity: Medium)

In high-risk areas like Google’s dark web analysis, there is room for AI to produce false positives or miss threats [11].

  • Mitigations
    • Have humans re-check important alerts
    • Require the reasoning behind AI decisions to be displayed
    • Double-check high-risk cases

Practical guardrails for day-to-day operations

  • Require human approval for high-risk operations
  • Handle confidential data in separated environments
  • Fix output formats as much as possible to JSON or templates
  • Clarify who is responsible for review
  • Keep logs and evidence so results can be traced later [21]
  • Evaluate AI adoption not by convenience, but by how low the incident rate is
