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
# Rubash GNU Bash Compatibility Skill ## Scope Use this skill for GNU Bash 5.2.21 compatibility work in this repository. Fix semantic owners, not individual expected-output lines or upstream bridge artifacts. ## Required evidence 1. Read the compatibility plan, suite diff analysis, issue ledger, and GNU source map before editing. 2. Compare script files with WSL GNU Bash 5.2.21. The authoritative verdict is: `MSYS_NO_PATHCONV=1 wsl bash tests/gnu-compat/run-83.sh check <NAME>`. 3. Keep raw outputs under `target/issue-suites/results/`; record interpretation in `docs/`. 4. Record the GNU source/test body, Rust semantic owner, minimal probe, exit status, stdout, stderr, and timeout before claiming a fix. 5. Never use Git Bash, the winuxsh `bash` shim, raw `.right` parity, or relay output as the sole baseline. ## Shared-tree handoff rules - Read the current tree before editing. Do not stash, reset, or overwrite another agent's work. - `src/lexer/continuation.rs` is captain-exclusive; send proposed changes instead of editing it. - Every edit must leave `cargo build` clean. Do not leave debug prints, partial migrations, or generated junk. …

How to install
mdr add unixwin/rubash/SKILL.md@sha256:1a0524c92cc2aeb7The line at the top of this page pins the label git:20260926.18cb41a, 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.
