Prompting Claude Fable 5: What to Change and What to Delete

Prompt Claude Fable 5 with less, not more: brief instructions now beat enumerated rule lists, and old skills written for prior models can degrade output. Use effort as your main cost control, expect longer turns, ground progress claims in tool results, and configure fallback to Opus 4.8 for safeguard refusals.

Prompting Claude Opus 5: Trim the Verbosity, Delete the Verification

Claude Opus 5 needs opposite prompting from its predecessors: you prompt for conciseness because effort no longer controls visible length, and you delete verification and double-check instructions because the model already does both. Constrain scope on narrow tasks, cap subagent spawning for cost, and keep thinking enabled at low effort rather than disabling it.

Prompting GPT-5.6: Message Roles, Effort, and Agentic Prompts That Work

GPT-5.6 rewards precise, explicit prompts: structure developer messages as identity, instructions, examples, then context, keep stable content first for prompt caching, and pick reasoning effort deliberately (xhigh for complex multi-step work). Move saved prompt objects into code before OpenAI shuts down v1/prompts on November 30, 2026.

Claude Code Subagent Patterns: 10 Reusable Agent Definitions

A Claude Code subagent is a delegated worker with its own context window, defined as a markdown file with YAML frontmatter in .claude/agents/. Subagents can edit files when you grant Edit or Write, nest three layers deep by default, and run 20 at a time. These 10 definitions cover the highest-value delegations.

Claude Opus 4.7 Best Practices: How to Actually Get the Most Out of the Upgrade

Claude Opus 4.7 follows instructions more literally than 4.6, runs longer agentic tasks more reliably, and ships a new xhigh effort level. Anthropic's launch-day guidance is to specify the task up front, batch your interactions, use auto mode, and default to xhigh; this guide adds the verification, recap, and scoping habits that make those gains show up in your sessions.

Master Claude Code's 1M Context Window: Rewind, Compact, Clear, and Subagents

Claude Code's 1M token context window opens longer autonomous sessions but introduces 'context rot' -- degraded performance as the window fills. Master four turn-end tools: /rewind to drop bad branches, /compact to summarize and continue, /clear to start fresh with a distilled brief, and subagents to wall off noisy work in their own context.

Ramp Glass Playbook: Internal AI Workspaces for Company-Wide AI Adoption

Glass is Ramp's internal AI productivity suite, built after the company had already hit 99 percent AI adoption and found most employees still stuck on setup. One Okta SSO sign-in wires up every tool, a marketplace called Dojo holds 350+ shared skills, memory is mined from Slack, Notion, Linear and Calendar, and jobs run on cron. Here is the playbook other companies can borrow.

Prompt Engineering in 2026: The Playbook That Works Across Claude and GPT

Prompt engineering in 2026 has two layers: cross-model fundamentals (clear direct instructions, motivated rules, 3-5 structured examples, XML boundaries, long documents before the question) and model-specific overrides that matter more than ever, because the newest models need instructions deleted as often as added. Start here, then apply the guide for your model.
