How to Give AI Agents a Work Procedure Manual: Design in 8 Ways, Shown Through a Scheduling Case
- Agent Skills are work procedure manuals written so that AI can read and follow them. Using scheduling as an example, the author explains how to write steps that first ask for missing information, then calculate free time, and then get human approval before anything is sent externally.
- The author advises leaving processing that has a single correct answer, such as date calculation or conflict checks, to scripts, and having AI handle only judgment and writing. The stated reason is to ensure the same input always produces the same result.
- The author's team records the reasons behind its judgment criteria, keeps past failure cases as automated tests, and runs trial operations in which a new AI session with no prior information runs the procedure alone to find gaps. This is the author's team's operating method and has not been verified externally.
Unfortunate 9 patterns often seen in AI-written code comments
- Many comments simply restate what the code already makes clear. The original article recommends removing such comments and writing why something is done only when truly needed.
- A comment should sit directly above the code it explains. If a note about a specific step inside a method is placed above the method definition, it is easily mistaken for a description of the whole function.
- According to the original, information such as past change history or specific call sites is better placed in commit messages, pull request descriptions, or comments in the calling code than in code comments.
- The original author says AI-written comments should not be trusted as-is and should be reviewed by people. They also suggest organizing comment rules into an AI instruction file such as CLAUDE.md.
Defense rocket motor startup Firehawk raises a Series D of $150 million
- Firehawk Defense makes solid rocket motors that propel shells and missiles, and the propellant that goes into them. Solid propellant is a mass in which fuel and oxidizer are hardened together.
- The conventional method mixes batches in pots and takes weeks to cure. The company claims that a continuous process, which melts and mixes thermoplastic materials with heat, produces the raw material within hours. Foreign media reported that a process that once took around 60 days was cut to the order of 6 hours.
- The company stated that it aims to become the largest shell motor maker in the United States and the No. 3 propellant producer by the end of 2027. The company announced that Hydra-70 rocket live-fire tests at the Yuma test site in August were 100% successful.
- Advent International and Rochefort Asset Management jointly led a Series D of at least $150 million. According to the company, its valuation is at least $1.4 billion, compared with the $290 million estimated by foreign media during the previous Series C round.
