username-recon skillA
username-recon is agent-read markdown (skill) from fmind/dot: Check public usernames with Sherlock; scope searches, verify matches, and preserve evidence..
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
# Public Username Reconnaissance Use `sherlock-project/sherlock`, distributed as `sherlock-project`, for public username checks within the requested scope. Keep targets, techniques, time window, and stop conditions explicit. Reconnaissance does not authorize exploitation. Stop on scope escape or unexpected impact; another technique needs its own bounded procedure. ## Workflow 1. Establish the exact usernames, selected sites, purpose, and output destination from the request. Treat a username match as a lead, not proof of a person's identity. 1. Inspect `uvx --from 'sherlock-project==<version>' sherlock --help` and `--version`, resolving `<version>` to a reviewed exact release so a run never executes newly published code; use the installed help because published website examples may lag the CLI. 1. Run only the selected sites, with a bounded per-request timeout, in a private output directory. For one authorized username, adapt: ```bash uvx --from 'sherlock-project==<version>' sherlock <username> --site GitHub --timeout 10 --output results.txt ``` …
Read the whole file at its exact version.
How to install
mdr add fmind/dot/username-recon@git:20260919.4491844mdr add fmind/dot/username-recon@sha256:21f82dd5913038d7Pin 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.
