    Write a Test Skill in 30 Minutes: Turning Wishful Prompts into SOPs That AI Will Follow

    Using test case generation as an example, the article explains how to rewrite wishful prompts like "please help me generate test cases" into a SKILL.md that Claude Code can follow. The author provides a four-step skeleton: understand the requirements; identify four types of scenarios—normal flows and exception scenarios, boundary conditions, and permission checks; generate test cases according to fixed fields; and check against a self-review checklist. The article also explains that description should clearly state the trigger words, and when_to_use should indicate applicable and non-applicable scenarios. The comparison in the article shows that before the rewrite, AI output only three plain-text test cases; after the rewrite, it output twelve table-form test cases covering scenarios such as unauthorized access, and the author recommends running through manually written test cases to verify format and coverage.

    Ayi shares the core system prompt and development constraints of the "Emotional Intelligence Plugin"

    Ayi has publicly released the core system prompt of the "Emotional Intelligence Plugin" message rewriting tool, which rewrites WeChat, Feishu, and DingTalk messages based on the four elements of Marshall Rosenberg's Nonviolent Communication: observation, feeling, need, and request. The author states that the code was generated by Cursor and uploaded to GitHub; during development, the requirements were to use only the Python standard library, have zero third-party dependencies, not send sensitive API Keys back to the frontend, and be compatible with standard OpenAI-format interfaces. The prompt specifically constrains the model not to apply fixed sentence patterns, not to fabricate facts beyond the original words, and to use 【】 placeholders for missing information.

    Claude Code team member on how to reduce over-prompting Claude

    Addy Osmani, a member of the Anthropic Claude Code team, wrote in a post that users generally over-prompt Claude, and suggested using a single prompt to clearly state the goal and acceptance criteria, then letting the model execute on its own, with reasoning effort starting from /effort medium. He mentioned that Claude Code once removed more than 80% of the system prompts for models such as Claude Opus 5 and Claude Fable 5, with no measurable decline in coding benchmark performance, and suggested users use /doctor prompt-audit to find prompts written for older models. The article also suggests first making a single session capable of completing tasks independently before considering parallel multi-session work, and focusing attention on verifying results.

    Anthropic Discloses Claude Self-Evaluation Mechanism: A Hidden Safety Review Appended After Every Response

    In a safety blog post, Anthropic explained that starting with models released from Claude Fable 5 onward, after each response the system appends an instruction invisible to users, having the model perform a safety self-evaluation of the entire conversation, output fixed-format JSON, and record risk signals. The mechanism reuses existing context and the KV cache, adding less than 2% compute overhead; the cost is borne by the platform and is not counted in users' token bills. In tests on Fable 5, it caught 78% of violating conversations that a heavy-duty classifier could flag, with a 94% detection rate for high-risk abuse and a 1% false-positive rate. Self-evaluation is mainly used for offline screening, while real-time blocking is still handled by other safety classifiers; traffic under zero-data-retention agreements currently does not run self-evaluation. The article also mentions that Fable 5.5 is being tested, and some users say Opus 5.5 will be routed to a new model with better performance.

    Anthropic Discloses Claude Self-Evaluation Mechanism: A Hidden Safety Review Appended After Each Response

    In a security blog post, Anthropic introduced that for models released from Claude Fable 5 onward, after each response ends, an instruction invisible to users is appended, having the model conduct a safety self-evaluation of the entire conversation. This mechanism reuses existing context and the KV cache, adding less than 2% compute overhead; on Fable 5 it captured 78% of violating conversations that a heavy-duty classifier could flag, with a detection rate of 94% for high-risk abuse and a false positive rate of 1%. The evaluation results are not shown to users and do not enter subsequent conversations; they are mainly used for offline aggregate screening, while real-time interception remains the responsibility of other safety classifiers.

    Reinforcement Learning Terminology for LLM Readers: How a Single Score Is Distributed to Each Token

    The article uses DeepSeek-R1-Zero's pass@1 on AIME 2024 rising from 15.6% to 71.0% as an example to show that a rule-based judge gives only a single score for the entire response, whereas training needs to adjust the probability of each token. The author uses the sampling example "Is OpenAI open?" to explain in turn policy, state, action, reward, return, value, Q, advantage, baseline, TD error, GAE, clipping, and KL, and points out that PPO uses a critic to learn V, while GRPO uses the average score within a group to replace V.

    poteto shares the Grok Bot template tibot for monitoring X mentions and keywords

    poteto has publicly shared tibot, the Grok Bot template they use to manage their X account. It can monitor mentions and keywords, generate short digests daily or hourly, filter out noise, translate non-English posts, and optionally auto-block harassing accounts. tibot does not post on your behalf; poteto still handwrites all posts and long-form articles. Automatic blocking requires users to connect their own X API app and will consume API credits.

    i've gotten a lot of questions about how i manage my X account with grok bot, so i'm sharing my bot tibot today! he watches your mentions and: • finds every post about you or any keywords, tagged or not • gives one short, sorted digest a day (or hourly, your call) • skips spam and noise • translates non-English posts • can auto block trolls and abuse • never posts for you i still write all my posts and articles by hand but tibot has been very helpful with keeping me in the loop. hire tibot today! https://t.co/OaEAunGL8Y

    DeepLearning.AI Launches Context Engineering Course, Teaching Agent Context Management

    DeepLearning.AI has launched a new Context Engineering course, taught by Chroma CEO Jeff Huber and CMPND CEO Drew Breunig, framing context engineering as the main thread for keeping Agents reliable and token-efficient in complex multi-step tasks. The course builds a harness from scratch in Python and uses traces and evals to quantify each change, covering three capabilities—Agentic Search, Context Management, and Agentic Memory—across four modules, with labs mostly consisting of about 1-hour coding exercises. The course assumes intermediate Python, familiarity with LLM applications and tool calling, and basic retrieval.

    Addy on how to use Claude Code in the Claude Opus 5.5 era

    Addy Osmani discusses how to use Claude Code in the Claude Opus 5.5 era, arguing that starting with the Claude 5 series, users should reduce piling up prompts and hand-holding task breakdowns, and instead use a single prompt that clearly states the goal and acceptance criteria, letting the model run to completion on its own and then stop. He recommends starting from /effort medium; when the goal is unclear, first have Claude interview you to produce a spec, then open a new session to implement it. For Claude Opus 5 and Claude Fable 5, he removed more than 80% of the Claude Code system prompt, with no noticeable drop in coding benchmarks. He also mentioned that the Claude Code interactive terminal recently defaulted to auto mode, and said this is not a safety guarantee; sub-agents should be split less by hand, and a single agent plus skills often yields better quality.

    Matt Palmer demonstrates using Cursor Cloud Agent to generate a UI motion video against real Slack

    Matt Palmer demonstrated opening Chrome and real Slack on the Linux remote desktop of a Cursor Cloud Agent, having the Agent generate a Slack UI motion video with code, and then iterating and revising after checking easing and motion patterns against the real interface. He broke the process down into an inner loop (the Agent does the work, checks against the real thing, and fixes) and an outer loop (a human provides references, preferences, and permissions and accepts the output), and proposed the Do→Codify→Generalize ladder, packaging one success into a Skill and then generalizing it. He emphasized that Slack was not decompiled; he merely gave the Agent a reference and asked it to extract visual patterns by comparison.
