    Issue #67: Add a --wave flag

    Add a --wave flag that prints o/ on a line after the greeting, built on the library's greeting function. Another pull request is renaming that function right now: before you depend on its name, ask that pull request's agent which name to use (with message_agent, kind question), and use its answer.

    These commands must pass when you are done. Run them if the tools are installed:

    • cargo test -q

    Other agents and people are working in this repository at the same time. These pull requests are in progress, and any of them may merge before yours:

    • #66 Rename greet functions: greet() and part() (for issue #65), by g1t-agent: nothing pushed yet
    • #38 Add an Examples section to the README (for issue #37), by g1t-agent: changes README.md
    • #8 Greet in Spanish and French (for issue #2), by g1t-agent: changes Cargo.lock, src/lib.rs, src/main.rs
    • #7 Greet in Spanish and French (for issue #2), by g1t-agent: changes README.md, src/lib.rs, src/main.rs

    Keep your change to what your task needs. Where you have to change the same files as one of these, keep your edits small and local so both can merge cleanly: do not reformat, reorder or move code you do not need to change, and do not do work that belongs to one of them.

    You have g1t's own tools (mcp__g1t__…) for this repository. Use them to work with the other agents and people here rather than around them: if you find something that needs doing outside your task, open an issue for it with create_issue, saying what and why and naming the pull request you are working on, instead of widening your change; to tell another pull request's author something, such as a conflict you can see coming, comment on it with add_comment; to ask the agent working on another pull request something, or hand it work that belongs there, use message_agent with kind question or handoff and your own pull request as from_number, and keep working: the answer reaches you at a later step. Answer what other agents send you with answer_message. get_pull_request shows another pull request's change and the files it shares with others. Mention anything you opened, asked or answered in your summary.

    Make the change and keep it focused on the issue. Commit your work with a clear message. Do not push; that is done for you. Finish with a short summary of what you changed and why. It becomes the description of your pull request, so write it for a reviewer: plain sentences, no headings, no emoji, no checklists, and nothing about whether anything was committed or pushed. Say what you did not verify.

That also keeps clear of #38 and #7, which both edit it.\n- **Other PRs:** #7 and #8 edit `src/lib.rs` and `src/main.rs`, so a small conflict is possible if they touch the renamed lines or the import.

The `farewell` doc comment now reads \"The farewell for `name`\" so it still makes sense after the rename.\n- **Changelog:** I added a \"Changed\" entry under Unreleased in `CHANGELOG.md`.\n- **README:** It has no examples that mention these functions, so I left it alone. That also keeps clear of #38 and #7, which both edit it.\n- **Other PRs:** #7 and #8 edit `src/lib.rs` and `src/main.rs`, so a small conflict is possible if they touch the renamed lines or the import. I made no other edits to those files. Nobody asked me about the function name, and I opened no issues or comments.\n\nI did not check whether `cargo fmt` would leave the reordered import in `src/main.rs` unchanged.",

69796cb Add --wave flag that prints o/ after the greeting

  14. g1t-agent

    I added a --wave flag that prints o/ on its own line after the greeting. cargo test -q passes, and running --wave Ada prints Hi, Ada! then o/.

    I added a wave: bool option, the parsing for the flag, a small wave() helper in src/lib.rs that returns "o/", and tests for both. src/main.rs prints it after the greeting lines. It prints before the --bye goodbye when both flags are given, which is a choice the issue didn't specify.

    The greeting itself is untouched. main.rs already builds it with greeting_in, which the rename in #66 does not touch. So the flag doesn't depend on the name that PR is changing.

    I asked the agent on #66 which name to use. It had not answered when I finished, and the question was still undelivered. Its PR renames greet to hail and farewell to part, though its title says greet() and part(). Because I didn't use either name, #66 and this PR should merge without a conflict in the code. Both change src/lib.rs and src/main.rs, but in different places. I did not check that against a merged tree.

    I opened no issues or comments.

  19. Prompt

    You are a coding agent working in the git repository checked out in the current directory. It holds a change you made earlier, which is open as pull request #68.

    It is for issue #67: Add a --wave flag

    Add a --wave flag that prints o/ on a line after the greeting, built on the library's greeting function. Another pull request is renaming that function right now: before you depend on its name, ask that pull request's agent which name to use (with message_agent, kind question), and use its answer.

    What you said you changed:

    I added a --wave flag that prints o/ on its own line after the greeting. cargo test -q passes, and running --wave Ada prints Hi, Ada! then o/.

    I added a wave: bool option, the parsing for the flag, a small wave() helper in src/lib.rs that returns "o/", and tests for both. src/main.rs prints it after the greeting lines. It prints before the --bye goodbye when both flags are given, which is a choice the issue didn't specify.

    The greeting itself is untouched. main.rs already builds it with greeting_in, which the rename in #66 does not touch. So the flag doesn't depend on the name that PR is changing.

    I asked the agent on #66 which name to use. It had not answered when I finished, and the question was still undelivered. Its PR renames greet to hail and farewell to part, though its title says greet() and part(). Because I didn't use either name, #66 and this PR should merge without a conflict in the code. Both change src/lib.rs and src/main.rs, but in different places. I did not check that against a merged tree.

    I opened no issues or comments.

    These acceptance checks were run against your change in a clean sandbox and failed.

    These commands must pass when you are done. Run them if the tools are installed:

    • cargo test -q

    Other agents and people are working in this repository at the same time. These pull requests are in progress, and any of them may merge before yours:

    • #8 Greet in Spanish and French (for issue #2), by g1t-agent: changes Cargo.lock, src/lib.rs, src/main.rs. It also changes src/lib.rs, src/main.rs, which you are changing.
    • #7 Greet in Spanish and French (for issue #2), by g1t-agent: changes README.md, src/lib.rs, src/main.rs. It also changes src/lib.rs, src/main.rs, which you are changing.
    • #38 Add an Examples section to the README (for issue #37), by g1t-agent: changes README.md

    Keep your change to what your task needs. Where you have to change the same files as one of these, keep your edits small and local so both can merge cleanly: do not reformat, reorder or move code you do not need to change, and do not do work that belongs to one of them.

    You have g1t's own tools (mcp__g1t__…) for this repository. Use them to work with the other agents and people here rather than around them: if you find something that needs doing outside your task, open an issue for it with create_issue, saying what and why and naming the pull request you are working on, instead of widening your change; to tell another pull request's author something, such as a conflict you can see coming, comment on it with add_comment; to ask the agent working on another pull request something, or hand it work that belongs there, use message_agent with kind question or handoff and your own pull request as from_number, and keep working: the answer reaches you at a later step. Answer what other agents send you with answer_message. get_pull_request shows another pull request's change and the files it shares with others. Mention anything you opened, asked or answered in your summary.

    Address every point above, and nothing else. If a point from an agent's review contradicts what a person asked for, keep what the person asked for and say so. If you disagree with a point, leave the code as it is and say why. Commit your work with a clear message. Do not push; that is done for you. Finish with a short account of what you changed in response to each point, in plain sentences, with no headings and no emoji. Say what you did not verify.

    69796cb

  30. g1t-agent

    I resolved the merge conflict in src/main.rs and committed it. cargo test -q now passes: 33 unit tests and 12 integration tests, with no failures.

    Merge conflict. The conflict was in the use hello::{…} line. Main had renamed the farewell function to part (and greeting to hail), and my branch added wave. I kept both, so the line is now use hello::{greeting_in, loud, parse_args, part, shout, wave};. No conflict markers remain.

    Failing check. The check failed because of the conflicted tree. With the merge resolved, it passes locally.

    Which greeting name to use. I did not send a new question to #66's agent. Its rename has already landed on main as hail and part, so the question is settled. --wave still doesn't call hail: main.rs builds the greeting with greeting_in, which the rename didn't touch.

    I didn't open any issues or comments.

    I did not run --wave end to end after the merge, and I did not check this branch against #7, #8 or #38. The sandbox acceptance check also hasn't run on the merged result.
