It opens a pull request from `release-` that bumps the version in `Cargo.toml` and `Cargo.lock` and nothing else. Its body is a summary of the release, then the version diff. `claude -p`, with no tools, writes the summary from the version diff and the title, number and body of each pull request merged since the last tag, following the prompt in [`scripts/release-summary.md`](scripts/release-summary.md). If `claude` fails or prints nothing, the script warns and uses GitHub's generated notes as the summary instead, with a note saying so. It writes the summary before it pushes anything. With `--review` (`scripts/release.sh --review 0.4.0`), it then prints the summary and asks `[y]es / [e]dit / [n]o`: `y` carries on, `e` opens the summary in `$EDITOR` and carries on with what you save, and `n` stops with no branch, pull request or tag pushed. Without `--review` it never prompts. It waits for the pull request's checks, merges it with a merge commit, then tags that merge commit `v` and pushes the tag.

If the release workflow run fails, it exits `1`, naming the failed jobs and the run's URL, and leaves the tag in place: the tag is already public, so rerun the failed jobs with `gh run rerun --failed ` rather than cutting a new version.

It opens a pull request from `release-` that bumps the version in `Cargo.toml` and `Cargo.lock` and nothing else. Its body is a summary of the release, then the version diff. The User config’s default Harness, with its configured Model and Effort (Claude Code when no default is set), writes the summary from the version diff and the title, number and body of each pull request merged since the last tag, following the prompt in [`scripts/release-summary.md`](scripts/release-summary.md). The script uses `cargo run` in this checkout to share thirdshift’s config parser and Harness adapters, and runs the summary in a temporary directory without Factory skills. Claude’s tools stay disabled. If the config is invalid, the chosen Harness fails, or it returns no summary, the script warns and uses GitHub's generated notes as the summary instead, with a note saying so. It writes the summary before it pushes anything. With `--review` (`scripts/release.sh --review 0.4.0`), it then prints the summary and asks `[y]es / [e]dit / [n]o`: `y` carries on, `e` opens the summary in `$EDITOR` and carries on with what you save, and `n` stops with no branch, pull request or tag pushed. Without `--review` it never prompts. It waits for the pull request's checks, merges it with a merge commit, then tags that merge commit `v` and pushes the tag. Pushing the tag starts the release workflow (below), and the script then waits for that workflow's run on the merge commit, printing the run's URL so you can watch it. CI's run on `main` for the same commit isn't waited for. Once the release workflow run succeeds, the GitHub Release is published with its final body and the crate is on crates.io, and the script prints the GitHub Release's URL and exits `0`. It prints a line on stderr for each step. If the checks fail, it stops before merging and leaves the pull request open. If the release workflow run fails, it exits `1`, naming the failed jobs and the run's URL, and leaves the tag in place: the tag is already public, so rerun the failed jobs with `gh run rerun --failed ` rather than cutting a new version. Neither wait has an overall timeout. Before it pushes anything, it refuses a release that can't be cut and says why: a version that isn't plain `X.Y.Z` (no leading `v`), a version that isn't higher than the one in `Cargo.toml` on `origin/main`, a `v` tag that already exists locally or on origin, or a latest CI run on `origin/main` that failed or hasn't finished. diff --git a/scripts/release.sh b/scripts/release.sh index d059a6c1..d21c3d35 100755 --- a/scripts/release.sh +++ b/scripts/release.sh @@ -7,11 +7,11 @@ # # Usage: scripts/release.sh [--review] # -# Run it in a clone of this repo, signed in to gh and with claude logged in.

Each now drops its bypass and runs with as few tools as its CLI allows, verified against the real CLIs: - Grok: only todo_write, without the MCP gateways or web search. - Muse: approval and sandbox on, no shell, writes or web, and one model step, so a file read can never reach the summary. - OpenCode: no --auto, and a deny-all permission config through OPENCODE_CONFIG_CONTENT, which holds even with --auto. - agy: headless mode denies every tool that needs a permission; adds --sandbox, --disable-slash-commands and a 10-minute print timeout. File reads remain possible. agy's stream-json input needs an "event" field, not "type": the summary failed with every real agy before this.

It prints a line on stderr for each step. If the checks fail, it stops before merging and leaves the pull request open. If the release workflow run fails, it exits `1`, naming the failed jobs and the run's URL, and leaves the tag in place: the tag is already public, so rerun the failed jobs with `gh run rerun --failed ` rather than cutting a new version.

Codex runs read-only and sandboxed, with its shell, MCP, web, app, plugin, browser and hook tools off. Grok gets only its to-do tool. OpenCode refuses every tool call. Muse has no shell, writes or web, and one model step. agy denies every tool that needs a permission, though it can still read files.

With `--review` (`scripts/release.sh --review 0.4.0`), it then prints the summary and asks `[y]es / [e]dit / [n]o`: `y` carries on, `e` opens the summary in `$EDITOR` and carries on with what you save, and `n` stops with no branch, pull request or tag pushed. Without `--review` it never prompts. It waits for the pull request's checks, merges it with a merge commit, then tags that merge commit `v` and pushes the tag. Pushing the tag starts the release workflow (below), and the script then waits for that workflow's run on the merge commit, printing the run's URL so you can watch it. CI's run on `main` for the same commit isn't waited for. Once the release workflow run succeeds, the GitHub Release is published with its final body and the crate is on crates.io, and the script prints the GitHub Release's URL and exits `0`. It prints a line on stderr for each step. If the checks fail, it stops before merging and leaves the pull request open. If the release workflow run fails, it exits `1`, naming the failed jobs and the run's URL, and leaves the tag in place: the tag is already public, so rerun the failed jobs with `gh run rerun --failed ` rather than cutting a new version. Neither wait has an overall timeout. Before it pushes anything, it refuses a release that can't be cut and says why: a version that isn't plain `X.Y.Z` (no leading `v`), a version that isn't higher than the one in `Cargo.toml` on `origin/main`, a `v` tag that already exists locally or on origin, or a latest CI run on `origin/main` that failed or hasn't finished. diff --git a/scripts/release-summary.md b/scripts/release-summary.md index a38382c3..c9c4bb57 100644 --- a/scripts/release-summary.md +++ b/scripts/release-summary.md @@ -1,5 +1,7 @@ Write the summary of a thirdshift release for its release pull request and its GitHub Release page.
