Render a before/after telemetry delta bracketing a methodology-change.
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
# /ds-change-delta Render a before/after telemetry delta bracketing a methodology-change "cut point" - a git commit SHA or an ISO8601 date. Answers "did this specific commit help or hurt" by re-deriving sessions, subagent spawns per session, hook denies per session, tokens per session, wall time per session, and (for a git-checkout `--repo` with a resolvable `gh` remote) commits per merged PR, for two equal-length windows either side of the cut point, from the same live telemetry stores `ds-cost`, `ds-evaluate`, `ds-hook-fire-report`, and `ds-branch-prune` already read. The `eval` block adds the same comparison over `ds-eval`'s figures (cost-state dollars per session), split by entrypoint and stated with its confounders. Implementation: `bin/ds-change-delta` (Python 3 stdlib). ## Usage ``` ds-change-delta --cut <SHA|ISO8601> [--cut-repo PATH] [--window-days N] [--pr-lookahead-days N] --repo PATH [--repo PATH ...] [--json] [--no-eval] ``` - `--cut` (required): a git SHA (resolved to its **committer** date on `--cut-repo`, deliberate for a squash-merge repo) or an ISO8601 date/datetime. A 7-40 hex-char argument is tried as a SHA FIRST …

How to install
mdr add space-dinosaurs/dinostack/ds-change-delta@sha256:d5ddc61bbbbe1a18The line at the top of this page pins the label git:20261013.6312bb0, 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.
