Claude Code Security: Permissions, Prompt Injection, and Secrets

A security guide for Claude Code identifies prompt injection, exposed API secrets, and overly broad permissions as the primary risks when using the AI coding agent. It recommends keeping untrusted content separate from instructions, restricting agent access to secret names rather than raw credent...

Your AI pipeline is broken, and your dashboards don’t know it

A RAG pipeline used by a corporate client generated false stock recommendations for three days while health dashboards showed no errors, caused by a prompt template change that led the LLM to ignore retrieved context. The incident illustrates that standard monitoring tools fail to detect AI syste...

Model Routing: Stop Using One Model for Everything

Model routing is a technique that directs AI tasks to appropriately sized language models based on complexity, cost, or latency requirements. The approach maps tasks such as classification to 1-3B parameter models and complex reasoning to 14-32B+ models, with four strategies: capability-based, co...

Why AI Agents Need Runtime Budgets Before Provider Calls

A developer guide argues that AI agent cost controls should execute before provider API calls rather than relying on post-run dashboards, since agents run in multi-step loops where costs accumulate across retries, tool calls, and planning steps. Proposed runtime checks include budget limits, max-...

How pull request limits are cutting down the noise

GitHub introduced pull request limits, a configurable feature that caps the number of open pull requests a user without write access can have in a repository at one time. AI-generated pull requests count toward the limit, draft pull requests do not, and trusted contributors can be added to a bypa...

Cost Optimization for LLM Systems: Where the Money Actually Goes

LLM inference costs scale linearly with usage, reaching roughly $365 annually at $0.01 per request for 10,000 daily requests. Common cost-reduction approaches include per-session and per-task token budgets, and routing tasks to smaller models based on complexity.

LLM Guardrails in Practice: What Actually Works

A technical guide outlines practical LLM guardrail strategies, including regex-based prompt sanitization to detect injection patterns like "ignore previous instructions" and input length limits capped at 10,000 characters to prevent token waste and timeouts.

Multi-Model System Design: When One Model Isn't Enough

Multi-model AI system design can follow five architectural patterns — single, sequential, parallel, hierarchical, and ensemble — each with distinct complexity and cost tradeoffs. Sequential pipelines chain specialized models in steps, while ensemble approaches aggregate outputs from multiple mode...

What I Learned Running Airtable AI Across Three Regions at p99

A software team deployed Airtable AI across three geographic regions (us-east, eu-west, ap-southeast), achieving 99.94% uptime and p99 latencies under 1.8 seconds by routing traffic across multiple models priced between $0.01 and $3.50 per million tokens. GPT-4o handled 5% of traffic for complex ...

Construindo um ranking da Copa pareando com o Claude Code: o relato de uma sessão

A developer used Claude Code to build a player-ranking pipeline for the 2026 FIFA World Cup, scraping 24 official FIFA match PDFs and cross-referencing individual player statistics to produce per-position ratings for each round. The session involved debugging HTTP errors, a misidentified subdomai...

I published my first GitHub Marketplace Action: Aster Guard MCP

Aster-Works published Aster Guard MCP (v0.3.2) to the GitHub Marketplace, a static scanner for MCP and Claude Code configuration files that checks for hardcoded secrets, hidden agent instructions, dangerous shell commands, and sensitive file paths without executing the configurations it scans.

The Pulse: Big implications of US banning Anthropic’s new model, Fable

The US government restricted access to Anthropic's new AI model "Fable" to US citizens only, a move analysts say could push non-US companies and countries toward Chinese open-source models. SpaceX also went public, with Elon Musk acquiring Cursor, which in turn acquired the Continue coding tool.

Fable 5 ban: 4 open models responded before Anthropic could restore access

The U.S. government ordered Anthropic to suspend its Fable 5 and Mythos 5 models for all foreign nationals, citing national security and export-control rules over an alleged jailbreak; Anthropic disabled both models globally. In the same week, Cohere, Moonshot, and Zhipu released open-weight codi...
