xh skillA
xh is agent-read markdown (skill) from fmind/dot: Inspect HTTP endpoints with bounded, credential-safe requests using xh..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# xh HTTP Inspection Use xh for bounded read-only HTTP inspection; debugging a known failure belongs to [systematic-debugging](../systematic-debugging/SKILL.md), and API research to [research-brief](../implementation-plan/references/research-brief.md). ## Workflow 1. **Confirm the target**: use an explicit trusted URL, ignore stdin, and start with headers so redirects and advertised size are visible without fetching a body. ```bash xh --ignore-stdin --check-status --timeout 10 HEAD https://example.com/health ``` 1. **Limit the displayed body**: request at most 64 KiB and cap displayed output even when a server ignores `Range`; do not add `--follow` until the redirect target is reviewed. ```bash xh --ignore-stdin --check-status --timeout 10 GET https://example.com/api Range:bytes=0-65535 | head -c 65536 ``` 1. **Protect credentials**: pass synthetic or environment-sourced authorization only to the intended origin. Use `--print=h` or `--body`; never `--verbose`, `--debug`, `--curl`, sessions, or request-header printing around secrets. …

mdr add fmind/dot/xh@git:20260923.2988db2mdr add fmind/dot/xh@sha256:ed08529087453c6ePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
