| 1 | //! Skills — named instruction bundles the agent can invoke. |
| 2 | //! |
| 3 | //! A skill takes one of two shapes, and both are skills in every other respect — same |
| 4 | //! frontmatter, same name resolution, same invocation: |
| 5 | //! |
| 6 | //! ```text |
| 7 | //! .daimond/skills/<name>.md a skill that is only instructions |
| 8 | //! .daimond/skills/<name>/SKILL.md a skill that also ships files |
| 9 | //! .../references/… documents it reads |
| 10 | //! .../scripts/… executable code it runs |
| 11 | //! ``` |
| 12 | //! |
| 13 | //! The directory form exists because a skill worth sharing is rarely only prose: it quotes a |
| 14 | //! reference document, or it runs a script. A directory that holds no `SKILL.md` is not a skill; |
| 15 | //! it is someone's notes, and it is skipped rather than complained about. |
| 16 | //! |
| 17 | //! The frontmatter is a light YAML-ish block: |
| 18 | //! |
| 19 | //! ```text |
| 20 | //! --- |
| 21 | //! name: review |
| 22 | //! description: Review a diff for bugs |
| 23 | //! uses: [file_read] |
| 24 | //! --- |
| 25 | //! <the markdown instruction body...> |
| 26 | //! ``` |
| 27 | //! |
| 28 | //! Skills are invoked two ways, and both end in the same place -- the file's text in front of the |
| 29 | //! model before the turn starts, rather than an instruction to the model to go and read it. |
| 30 | //! |
| 31 | //! The first is a slash command, `/name the rest of the message`, which is what a person types. |
| 32 | //! It is resolved by [`parse_command`] against the directories [`command_dirs`] names, and a name |
| 33 | //! that resolves to no file is REFUSED rather than sent on as ordinary chat: a user who types |
| 34 | //! `/pickup` and gets a plausible answer that skipped the workflow has no way to tell. |
| 35 | //! |
| 36 | //! The second is an angle-tag directive |
| 37 | //! `<name args...>`, optionally closed with `</name>` or a bare `</>`. |
| 38 | //! Parsing is deliberately tolerant (plan D9): only the *opening* tag is |
| 39 | //! terminated by `>`, so a `>` inside the body — such as `Vec<T>` or |
| 40 | //! `->` — is safe and does not end the directive. A missing `>` on the |
| 41 | //! opening tag recovers to end-of-line, and a missing closing tag |
| 42 | //! recovers to end-of-message. |

| 494 | // A skill is a file, and every skill was somebody's file first. That is right for the ones |
| 495 | // a person invents and wrong for the two that decide whether a day's work survives the tab: |
| 496 | // `/handover` and `/pickup` are the pair that turns an app which must be re-briefed every |
| 497 | // time into one that is already oriented, and until now a fresh workspace had neither, so |
| 498 | // the first thing anybody had to do was write them. `dev/PARITY.md` §2.1 called that the |
| 499 | // cheapest large win in the document and costed it at two text files; what it did not say |
| 500 | // is where the two files come from. Shipping them is where. |
| 501 | // |
| 502 | // Three rules hold the arrangement together: |
| 503 | // |
| 504 | // * **A file wins.** [`resolve_skill`] takes what the workspace found and hands the shipped |
| 505 | // text back only when the workspace found nothing, so writing `.daimond/skills/pickup.md` |
| 506 | // replaces this one exactly as deleting `prompts/daimon.md` restores that default. The |
| 507 | // precedence is a named function rather than the order of two branches in an async wasm |
| 508 | // path, because that ordering is the whole behaviour and nothing native could see it. |
| 509 | // * **They say where they came from.** [`shipped_path`] is not a workspace path, because |
| 510 | // there is no file there; `compose_command` puts it in front of the model, so a user |
| 511 | // reading the turn can tell a shipped skill from their own and can see which one ran. |
| 512 | // * **They name actions.** Measured on this codebase, a sentence that names an action |
| 513 | // changes what a model does and a sentence that names a prohibition does not, so every |
| 514 | // step below is a thing to do. `test_no_step_of_a_shipped_skill_is_a_bare_prohibition` |
| 515 | // is what keeps a later edit from drifting back into rules. |

| 525 | # Handover\n\ |
| 526 | \n\ |
| 527 | Write a handover now, into this Diamond's own folder -- its path is named at the top of your \ |
| 528 | instructions -- under `handover/`, as `<YYYY-MM-DD>-<nn>.md`. List that folder first and take \ |
| 529 | the next free number for today, so a second handover on the same day sits beside the first \ |
| 530 | rather than over it.\n\ |
| 531 | \n\ |
| 532 | Put these five sections in it, in this order, each carrying facts rather than a summary of \ |
| 533 | them:\n\ |
| 534 | \n\ |
| 535 | 1. Where the work stands: the objective, and how far it has got.\n\ |
| 536 | 2. What changed this session, each item naming the file it touched.\n\ |
| 537 | 3. What remains, each item naming the next action, in the order to do them.\n\ |
| 538 | 4. What is broken or unproven, and the command or check that would settle it.\n\ |
| 539 | 5. Read these first: every file the next session must open, in the order to open them, each \ |
| 540 | with one line saying why.\n\ |
| 541 | \n\ |
| 542 | Take each fact from the work itself: open the file again rather than quoting it from memory, \ |
| 543 | and where you are unsure of something, write that you are unsure of it.\n\ |
| 544 | \n\ |
| 545 | Then fold what the crystal is now missing into `crystal.json` -- the open threads especially -- \ |
| 546 | and tell the user the handover's path in one line.\n\ |
| 547 | \n\ |
| 548 | In an ordinary chat there is no Diamond and no folder that outlives it, so say that the work \ |
| 549 | wants a Diamond to be kept in, and write the same five sections into the reply instead.\n\ |

| 562 | \n\ |
| 563 | Read these four things, in this order, before you say anything:\n\ |
| 564 | \n\ |
| 565 | 1. List `handover/` in this Diamond's own folder -- its path is named at the top of your \ |
| 566 | instructions -- and read the newest file in it, whole. Where the user named a topic after the \ |
| 567 | command, read the newest one about that topic instead.\n\ |
| 568 | 2. Read this Diamond's `crystal.json`, which is already in front of you, against what the \ |
| 569 | handover says.\n\ |
| 570 | 3. Open every file the handover's `Read these first` list names, in the order it names them.\n\ |
| 571 | 4. Check the handover against the tree: open what it says it changed, and run what it says \ |
| 572 | would prove it. Where the two disagree, the tree is right.\n\ |
| 573 | \n\ |
| 574 | Then say in five lines or fewer where the work stands, what the handover got wrong, and the one \ |
| 575 | thing you are doing next -- and do it.\n\ |
| 576 | \n\ |
| 577 | Where there is no `handover/` folder or nothing in it, say so, say what you can see instead -- \ |
| 578 | the crystal, the folders attached to this Diamond -- and ask for the one thing you need to \ |
| 579 | start. In an ordinary chat there is no Diamond to look in: say that, and ask which Diamond \ |
| 580 | the work is kept in.\n\ |

| 593 | \n\ |
| 594 | Read three things before you answer, in this order:\n\ |
| 595 | \n\ |
| 596 | 1. This Diamond's `crystal.json`, which is already in front of you. Take the goal from it, and \ |
| 597 | take the open threads, which are the work that is not finished.\n\ |
| 598 | 2. The newest file in `handover/` in this Diamond's own folder -- its path is named at the top \ |
| 599 | of your instructions -- where there is one, for what the last session said it was doing.\n\ |
| 600 | 3. The tree itself: open what the crystal or the handover says was changed, and run whatever \ |
| 601 | would prove it. Where the two disagree, the tree is right.\n\ |
| 602 | \n\ |
| 603 | Then answer in five lines or fewer, in this shape:\n\ |
| 604 | \n\ |
| 605 | 1. The objective, and how far it has actually got.\n\ |
| 606 | 2. What changed since the last handover, taken from the files rather than from memory.\n\ |
| 607 | 3. What is running now, or the word `idle`.\n\ |
| 608 | 4. The single next action you recommend, in one line.\n\ |
| 609 | 5. A last line reading `Required from you:` and then the thing you really need -- an approval, \ |
| 610 | a choice, a file -- or `nothing`, and what you are proceeding with instead.\n\ |
| 611 | \n\ |
| 612 | Quote a number you have measured, and write `unmeasured` beside one you worked out by eye.\n\ |
| 613 | \n\ |
| 614 | In an ordinary chat there is no Diamond and no crystal, so say what you can see instead -- this \ |
| 615 | conversation, the folders attached to it -- and give the same five lines from that.\n\ |

| 626 | ---\n\ |
| 627 | \n\ |
| 628 | # Decisions\n\ |
| 629 | \n\ |
| 630 | Gather the decisions this work is really waiting on. Take them from this Diamond's `crystal.json` \ |
| 631 | open threads, from the newest file in `handover/` in this Diamond's own folder, and from what you \ |
| 632 | have just found in the tree -- a question you had to guess the answer to is a decision.\n\ |
| 633 | \n\ |
| 634 | Put them ONE AT A TIME, and put each one with the `ask` tool rather than in prose. It draws \ |
| 635 | your options as buttons, so the answer costs one tap -- and a decision answered by typing is a \ |
| 636 | decision put off. Its fields ARE these five things, and it refuses a call missing any of them:\n\ |
| 637 | \n\ |
| 638 | 1. `question` -- the decision in one sentence of plain words, naming the thing it decides.\n\ |
| 639 | 2. A concrete example of what each answer would mean -- what the user would see, or get, or \ |
| 640 | pay -- rather than the name of a category. Two to four of them go in `options`; each carries a \ |
| 641 | `means`, which is that example and the trade-off it brings, and a `label`, the words on its \ |
| 642 | button.\n\ |
| 643 | 3. Your recommendation, named as one of the options: `recommend`, matching a label exactly.\n\ |
| 644 | 4. The reason for it in one sentence, in the user's own terms -- their constraint, their cost, \ |
| 645 | their users -- as `why`; and `if_silent`, which is what you will do if they answer nothing.\n\ |
| 646 | 5. `Decision 1 of N` is `n` and `of`, so the user can see how many follow.\n\ |
| 647 | \n\ |
| 648 | Your turn ENDS when you call it. Do not restate the question in prose underneath the card. The \ |
| 649 | answer arrives as their next message: `Chose:` and the label they tapped, or `Other:` and words \ |
| 650 | of their own, which may reject every option you offered -- that is the answer, so take it.\n\ |
| 651 | \n\ |
| 652 | Where this page cannot draw a card the tool says so, and you ask in prose instead, with the \ |
| 653 | same five things.\n\ |
| 654 | \n\ |
| 655 | Take the answer, record it under the crystal's decisions with the reason the user gave, and go \ |
| 656 | on to the next one.\n\ |
| 657 | \n\ |
| 658 | Where a decision is yours to make -- the work has an obvious answer and being wrong is cheap -- \ |
| 659 | make it, say in one line that you did and why, and keep it off this list.\n\ |
| 660 | \n\ |
| 661 | Where you find nothing open, say so in one line and name the next action you would take instead.\n\ |
| 662 | \n\ |
| 663 | In an ordinary chat there is no Diamond and no crystal, so take the decisions from this \ |
| 664 | conversation and from the files attached to it, and put them the same way.\n\ |
