go-stdlib SKILL.md skillA
go-stdlib from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/go-stdlib@git:20261029.0a51226Pins git:20261029.0a51226 in mdr.lock. Pin the fingerprint instead.

Use when choosing or debugging Go standard-library APIs for Reader/Writer and file ownership, Scanner limits, JSON/CSV/XML decoding, UTF-8 and regex, time parsing, HTTP clients/servers, URL/path handling, slog, flags, randomness or database/sql; especially truncated input, unchecked flushes and unbounded reads.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Go Standard Library ## Route by boundary | Task | Load | |---|---| | Short reads/writes, Scanner, buffering, files, paths and fs.FS | [I/O and files](references/io-files.md) | | Text/bytes, conversion, regex, JSON/XML/CSV/base64/gob | [Text and encoding](references/text-encoding.md) | | Time zones/timers, context, HTTP, URLs and sockets | [Time and networking](references/time-network.md) | | Collections, errors, logging, flags, math/random/crypto and SQL | [Collections and runtime APIs](references/collections-runtime.md) | Load only the relevant local guide; no sibling or network access is required. ## Workflow 1. Read `go.mod`, build tags and dependencies. Establish supported language/library versions, input trust, byte/record limits and resource ownership. 2. Trace partial-data/error, borrowed-buffer, nil/empty, single-JSON/stream and buffered-output contracts. 3. Prefer existing stdlib operations. Separate decoding from domain validation: parsing URLs, paths or numbers neither authorizes nor validates their use. 4. Preserve errors/cancellation. Reuse HTTP clients and database pools; close per-operation bodies/rows/files at their actual lifetime boundary. …

How to install
mdr add lu1sdv/skillsmd/go-stdlib@sha256:57bf647e2dc53d9aThe line at the top of this page pins the label git:20261029.0a51226, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
