Internal kit of flights-lander — lander-inventory.py lists what a diff left behind (LEFT, LITERAL, GONE rows) and computes the review's spawn PLAN. Not invoked directly — ask flights-lander.
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
# lander-inventory
Run `python3 -I $HOME/.claude/skills/lander-inventory/lander-inventory.py {WORKTREE} {BASE} [HEAD] [--spec FILE …]`, the path written in full. Python 3 standard library; it reads the worktree through `git` and writes nothing. The diff is BASE against the working tree — commits, staged, unstaged and untracked work; with HEAD, the commits BASE..HEAD alone. Exit 0 prints the rows; exit 2 prints `FAILED` and the cause when git or the input breaks, or the usage line when an argument is missing.
- `LEFT`: a name the diff removed everywhere it touched, still in the tree outside history files.
- `LITERAL`: a name a code or data file dropped from inside a string or key on a replaced line.
- `GONE`: a file the diff deleted or renamed away, still named in the tree.
- `PLAN`: the spawn — `PLAN HUNTER` clusters (k = min(4, ceil(production diff lines / 600)), none at 400 lines or fewer), `PLAN WALKER` row ranges over each `--spec` file with 10 or more numbered rows (4 in all at most), `PLAN SUB-LANDER` ranges over the rows above by line number (6 at most).Read the whole file at its exact version.
How to install
mdr add rezzminator/professor/lander-inventory@sha256:9d4cbed30212365aThe line at the top of this page pins the label git:20261023.b99e150, 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.
