The Frontier Wire compared every per-prompt energy and water figure in its dataset. The extremes differ 2,300-fold for energy and over 1,600-fold for water, but four independent estimates for an ordinary text prompt sit within a factor of 1.75. Scope, request length and modality explain the rest.
An analysis of company sustainability reports in The Frontier Wire's AI water and energy dataset. Every one of the six companies that publish two years of water and electricity used less water per kilowatt-hour. None used less water. Together they added about 17.7 million cubic meters in a year.
A SKILL.md file changes what every coding agent on a team does the next time it loads. How to write descriptions that trigger, keep skills small, version and review them, pick a distribution model from git to plugin marketplaces to a private registry, and roll a bad release back.
The model is not a security boundary. Eight concrete failures in LLM apps and agents, from provider keys in browser bundles to injected tool calls and runaway spend, each mapped to the OWASP LLM Top 10, with the code-level fix and an open-source agent skill that audits a codebase for them.
A Claude Code skill is a folder of instructions the agent loads only when a task calls for it. Six MIT-licensed skills for security, observability, cost, MCP, coding-agent governance and skill management, ranked on stated criteria, installed and linted in a clean repository.
The open-source gateway's v2.3.0 release, out October 13, registers A2A agents by their agent cards, rewrites those cards to gateway endpoints, bridges transports, relays push notifications and gates every call on virtual-key grants. A v2.3.1 follow-up tightened destination and credential rules.
Maxim AI has published Bifrost CLI v1.0, a launcher that starts four terminal coding agents already routed through its open-source gateway, scoped to one process. It also signs developers in, shows their models and budget, and exposes the gateway's admin API to scripts and CI.
Maxim AI's endpoint agent for the Bifrost gateway gained per-app capture controls, version reporting and a stateless MCP inspection path in Bifrost Enterprise v2.3.0. How Edge works, what it governs, how it rolls out through MDM, and where it sits next to CASB and DLP tooling.
Decision models from TypeSafe, OpenAI, Perplexity, Cloudflare, Microsoft, Databricks and Ollama return typed answers with probabilities, in two request dialects. Bifrost v2.3.0 gives them one endpoint, stops silently answering decisions with chat models, and prices decisions on their own rates.
Warp, formerly called Odin, puts a tool-calling agent inside the Bifrost gateway's own dashboard. It reads logs, metrics and governance settings through a fixed set of read-only tools, searches logged conversations by meaning, and sees only the rows the person asking could already see.
Installing Claude Code takes a minute. Rolling it out to two hundred engineers without a surprise bill, a shared API key or an unknown MCP server on every laptop takes a plan: a provider choice, managed settings, one credential per developer, budgets, CI keys and a way to tell whether it is paying off.
A Codex skill is a folder with a SKILL.md file that the CLI and IDE extension find in .agents/skills and load when a task matches its description. Scan paths, the context budget, writing one that triggers, installing shared skills with npx skills, and six worth adding for LLM app teams.
Cursor loads Agent Skills from .agents/skills and .cursor/skills and lets the agent decide when each one applies. How that decision works, how skills compare with .cursor/rules and AGENTS.md, how to install shared skills with npx skills, and three skills that fix MCP sprawl and blind spots.
Every LLM bill is requests times tokens times price. A playbook for shrinking each factor without a quality regression: attribution, right-sized models, complexity routing, prompt trimming, prompt and response caching, Batch APIs, loop caps and budgets, plus the open-source llm-cost-reduction agent skill.
A practical explainer on LLM observability: the per-call record, time to first token, OpenTelemetry GenAI conventions, trace structure for agents, sampling and PII redaction, Prometheus alert thresholds, feedback joins and evals on production traffic, plus the open-source llm-observability-stack agent skill.
Connecting one MCP server takes a line of config. Running twenty safely across a team takes tool budgets, per-identity allow-lists, approval gates, sane transports, health checks and logs. The practices, checked against the 2026-07-28 MCP specification, and an open-source agent skill that audits a setup against them.
The skills CLI installs SKILL.md folders from GitHub into 79 coding agents, and skills.sh is the directory built on its telemetry. Every command in version 1.7.4, project and global scope, the symlink layout, the lock file and its hashes, and the warning printed on every install, checked against the source.
Every major API management platform now ships some form of AI gateway. The criteria below separate the platforms built to publish and monetize APIs from the layer built to meter tokens, fail over between model providers and govern MCP tools, and compare twelve options against both.
NIST defines attribute-based access control as decisions made from attributes of the subject, the object and the environment. The architecture behind it, how it differs from RBAC and Google's Zanzibar-style ReBAC, the policy languages that implement it, and how to apply it to models, agent tools, MCP servers and RAG.
Claude usage is measured three different ways depending on how a request signs in. Subscriptions run on five-hour and weekly windows, API keys run on rate limits and spend caps, and usage-based Enterprise seats are billed per token. Where each meter lives and what drains it, per Anthropic's pages on 21 October 2026.
