    A Migration Must Know Which Symlinks It Owns

    The agentic-coding-toolkit changelog describes a migration from command wrappers to skills. One release removed stale toolkit-owned links while preserving user-managed entries. That sentence is short. The filesystem decision behind it is not. An installer may already have created aliases in several host directories.…

    A Source Transformer Should Be Allowed to Say No

    The most reassuring response from a source-editing tool is not always a successful edit. Sometimes it is: “There is no safe value at this cursor position.” That sounds like a disappointing feature. A keyboard shortcut was pressed; surely the extension should do something. But automatic edits have an awkward property:…

    Safe Automation Starts Before `--apply`

    The dangerous command is rarely the one that says it will delete everything. It is the tidy utility that loops across many repositories, opens a few pull requests, and promises to “save time.” At one repository, a mistake is a correction. At twenty repositories, it is a campaign. That is why the safety question for…

    If the OS Will Not Confirm It, Your Analytics Should Not Either

    Complete-sounding event names are tempting when an API returns a resolved promise. review_prompt_shown. review_completed. user_rated_app. They make dashboards wonderfully decisive. They can also describe events the application never observed. In-app review is a sharp example. An application may request the system…

    A Prompt Is Not Provenance

    An AI can turn a page of notes into a convincing paragraph surprisingly quickly. That is not the hard part. The hard part is answering a future question: where did this claim come from, who owns the decision to publish it, and what happens when the source changes next week? “The model saw it in the prompt” is not a…

    Runtime Boundaries Are Product Features

    The confusing bug was not a broken button. It was a feature that worked exactly where the architecture allowed it, and nowhere the user expected it. A Figma plugin can look like one small product: pick a node, generate some code, maybe refine it, maybe copy it. Under the hood, it can be two products with different…

    Your Vary Test Passed. Production Still Dropped Accept

    I had a content-negotiation test that passed. Then I asked production the same question. Production gave me the right body and the wrong evidence. That is an uncomfortable category of bug because the application appears to work. A client asking for HTML receives HTML. A client asking for Markdown receives Markdown. An…

    A 202 Accepted Is Not Zero Contributors

    One number on my GitHub profile card kept lying with excellent typography. Lines of code changed sometimes dropped to zero or came out suspiciously small. The failure mode was quiet: unavailable data could become a numeric zero inside an otherwise complete-looking SVG. Nothing in the card's shape explained why the…

    Redaction Is Not Omission: Publishing Private Work in a Public Coding-Stats Card

    I wanted to publish a tiny SVG card showing where my coding time went during the last seven days. Languages were easy. Projects were not. A public card might contain rows such as: The private project's real name is already absent in this example. WakaTime has supplied the placeholder Unknown Project. So the privacy…

    My Formatter Broke an Immutable Resume by Formatting It Correctly

    Part 2 of The Portfolio Is an Interface. I froze a resume snapshot, recorded its SHA-256 hash, and wrote a validator that rejected later edits. Then my formatter edited it. Prettier did not corrupt the Markdown. It did not delete a sentence, reorder a section, or hallucinate a new skill. It removed twelve blank lines.…

    Your Public Resume Should Be a Projection, Not a File Read

    Part 1 of The Portfolio Is an Interface. I wanted one resume file to feed everything: the Korean page, the English page, the printable documents, and the work pages on my portfolio. One source of truth, fewer places for a date or sentence to drift. Very tidy. Then I wrote a test fixture with a fake phone number in it…

    I Chose the Git CLI for a VS Code Extension—Then Had to Own stdout

    VS Code already ships with Git support. So when I started Minimal Git Explorer, the sensible shortcut was to ask the built-in Git extension for repository data. I deliberately did not take it. The built-in extension API is internal rather than an officially documented, versioned contract. Minimal Git Explorer instead…
