Its **System One models** return +fast, focused judgments that software can consume directly. **Jev** is TypeSafe's +flagship and first System One model. It understands natural language and returns +typed answers and probabilities rather +than generating text or reasoning explanations. Code owns the workflow; the model +supplies programmable common sense where ordinary code needs semantic understanding. + +## Read the live docs + +**The live TypeSafe docs are the source of truth. Read them as part of the task.** +This skill gives direction; the docs carry current concepts, prompting guidance, +API contracts, SDK usage, models, limits, and worked examples. + +- Start with the [documentation index](https://docs.typesafe.ai/llms.txt) to discover + relevant pages and cookbooks. Use targeted reads rather than loading the entire site. +- Mintlify serves Markdown by appending `.md` to a page path, for example + [how to build with TypeSafe](https://docs.typesafe.ai/concepts/how-to-build-with-system-one.md). + Follow links from the index; convert extensionless documentation page links to + `.md` when useful. Resolve relative links against `https://docs.typesafe.ai`. +- Before writing an integration, read the current API or chosen SDK page and the + question guidance relevant to the design. For a new workflow, also inspect the + closest cookbook: it often shows a better decomposition than a generic classifier. +- If the index is unavailable, use the direct links below or the site's navigation. + If Markdown fetching fails, try the normal page. If live access is unavailable, + use available local docs or installed SDK types, state that limitation, and avoid + inventing version-dependent details. + +| Task | Start here; follow the relevant details | +| --- | --- | +| Understand the programming model | [System One](https://docs.typesafe.ai/concepts/system-one.md), [building guide](https://docs.typesafe.ai/concepts/how-to-build-with-system-one.md) | +| Explore what to build | [Use-case map](https://docs.typesafe.ai/concepts/use-case-map.md), then relevant cookbooks from the index | +| Prepare inputs and questions | [State](https://docs.typesafe.ai/concepts/state.md), [primitives](https://docs.typesafe.ai/primitives.md), then the chosen primitive's page | +| Decide how to handle uncertainty | [Confidence](https://docs.typesafe.ai/confidence.md) | +| Write API code | [HTTP API](https://docs.typesafe.ai/api.md), [Python SDK](https://docs.typesafe.ai/sdk/python.md), or [JavaScript SDK](https://docs.typesafe.ai/sdk/javascript.md) | +| Update an older integration | [Migration guide](https://docs.typesafe.ai/migrating-to-v1.md) and the installed SDK's current reference | + +## Find the useful shape + +Start from the behavior the user wants: what will the application show, select, +change, or hand off? Work backward to the judgments it needs. Keep known rules, +calculations, exact lookups, and execution in code. Preserve the user's chosen stack +and scope; add TypeSafe where semantic understanding helps. + +When brainstorming or choosing an architecture, consider more than classification. +The patterns below are starting points: combine primitives around the user's goal, +including ideas that do not fit an established recipe. + +- **Route and fill known arguments.** A request can select a handler and its typed + parameters. Ask useful branch-specific questions up front and consume only the + relevant answers. Explore [function calling](https://docs.typesafe.ai/cookbooks/function_calling.md) + and [speculative fan-out](https://docs.typesafe.ai/patterns/fan-out.md). +- **Select instead of generate.** Find candidate values or source spans in code, + use a judgment to select the intended one, then copy or normalize it. Code can + also assemble source text into a formatted document or reading guide. Explore + [value extraction](https://docs.typesafe.ai/cookbooks/pre_parsed_value_extraction_cookbook.md) + and [structure recovery](https://docs.typesafe.ai/cookbooks/autoformat.md). +- **Find and judge evidence.** Retrieve candidates, compare their relevance to a + query, and select useful context. Explore [reranking](https://docs.typesafe.ai/cookbooks/rerank_typesafe.md) + and [hierarchical classification](https://docs.typesafe.ai/cookbooks/hierarchical_classification.md). +- **Turn judgments into reusable data.** Score dimensions once, then let code or + user controls change weights, thresholds, rankings, and views. With labeled + outcomes, those signals can become classical ML features. Explore + [composite scoring](https://docs.typesafe.ai/patterns/composite-scoring.md) and + [feature discovery](https://docs.typesafe.ai/cookbooks/autoresearch_feature_discovery.md). +- **Verify and escalate.** Check specific claims or fields against their evidence; + send uncertain or failing cases to a person or reasoning model. Explore + [citation checks](https://docs.typesafe.ai/cookbooks/citation_check.md) and + [extraction cascades](https://docs.typesafe.ai/cookbooks/sde_cascade.md). +- **Respond to changing state.** Code can retain goals and observations while fresh + judgments guide the next bounded step. Keep inferred state distinct from observed + facts, and check freshness before applying a result to a changed situation. + +For open-ended requests, offer the few directions that best serve the user's goal +and recommend a starting point. For a concrete request, choose the relevant pattern +and build; a brainstorm is not a mandatory detour. + +## Design the judgments + +Choose by what the answer means, then read the relevant primitive page: + +| Need | Primitive | Important distinction | +| --- | --- | --- | +| One of a defined set | [Choice](https://docs.typesafe.ai/primitives/choice.md) | Picks one option; its distribution compares competing options | +| Whether a condition holds | [Noul](https://docs.typesafe.ai/primitives/noul.md) | Probability of yes; no separate confidence; use one per label when several may apply | +| Degree along a described dimension | [Score](https://docs.typesafe.ai/primitives/score.md) | Probability-weighted position on ordered levels; use comparable per-item Scores for graded ranking | + +Give each question enough relevant **state** to answer: source text, identities, +relationships, policies, and current facts. Prefer named JSON fields when context +has several parts. Put the judgment in **instructions** and define its possible +answers in **criteria**. Question IDs are for code and are not sent to the model; +include complete meaning in the question. Reference nested state with backticked +paths such as `ticket.messages[0].text`. + +Ask one narrow, coherent judgment per question. Split independently useful dimensions, +without destroying the relationship being judged. A bounded action selection or +contextual interpretation is valid; atomic does not mean literal fact extraction +or a one-sentence limit. Strings work for simple questions. Use structured objects +or arrays when definitions, contrasts, exclusions, or examples clarify instructions +or criteria. Score levels must describe concrete situations and stand on their own. + +Keep the needed answers available. Include a no-match outcome when nothing may fit; +use a separate presence judgment when it is independently useful. For source-value +selection, check candidate coverage: the model cannot choose an omitted value. + +## Compose and verify + +**Ask independent questions over the same state together**, including useful +speculative questions. They run in parallel and cannot see one another's answers. +State each speculative premise explicitly; code consumes the applicable answers. +A second request is warranted when an earlier answer is needed to fetch evidence, +construct new state, or determine the next options. Extra questions still use tokens; +measure actual request budgets, cost, and end-to-end latency. + +Use probabilities and confidence to guide behavior, with thresholds evaluated on +the user's data and consequences. Choice/Score confidence summarizes distribution +concentration, not overall workflow correctness or permission to act. A Noul near +0.5 means similar probability for yes and no, not medium intensity. Several +acceptable alternatives can also spread probability; low confidence need not +invalidate a harmless preference choice. Ignore uncertainty on unused branches. + +Keep policy explicit and raw judgments reusable. Weighted scores suit compensating +preferences; an “any serious violation” rule needs separate conditions. Changing a +weight or display filter need not rerun inference when evidence and question meanings +are unchanged. Typed output guarantees the interface, not truth. System One models +are trained for calibrated decisions; validate their performance in the target domain. + +Test representative cases and the resulting application behavior. For failures, +inspect the exact state, questions, candidates, answers, composition, and observed +outcome. Separate missing evidence, model errors, code errors, and service failures. +Treat cookbook thresholds and demo results as examples to evaluate, not universal +rules or permanent model limitations. Keep API credentials server-side in web apps. diff --git a/skills-lock.json b/skills-lock.json new file mode 100644 index 00000000..734aa12e --- /dev/null +++ b/skills-lock.json @@ -0,0 +1,11 @@ +{ + "version": 1, + "skills": { + "typesafe-ai": { + "source": "typesafe-ai/skills", + "sourceType": "github", + "skillPath": "skills/typesafe-ai/SKILL.md", + "computedHash": "9cd84c5e535dec8dec59917c110f9c00b4a61faadb86b432ec7e41051170af12" + } + } +} From a9a463328e3e510a2d1696480852cea3e505ce54 Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Thu, 17 Sep 2026 19:03:03 +0530 Subject: [PATCH 02/14] Add the total approval gate --- crates/tinyhivemind-core/src/README.md | 1 + .../tinyhivemind-core/src/approval/README.md | 7 + crates/tinyhivemind-core/src/approval/mod.rs | 228 ++++++++ crates/tinyhivemind-core/src/approval/test.rs | 489 ++++++++++++++++++ .../tinyhivemind-core/src/approval/types.rs | 357 +++++++++++++ crates/tinyhivemind-core/src/lib.rs | 2 + crates/tinyhivemind-core/tests/public_api.rs | 14 + crates/tinyhivemind/src/README.md | 1 + crates/tinyhivemind/src/approval/README.md | 6 + crates/tinyhivemind/src/approval/mod.rs | 101 ++++ crates/tinyhivemind/src/approval/test.rs | 221 ++++++++ crates/tinyhivemind/src/approval/types.rs | 85 +++ crates/tinyhivemind/src/error/mod.rs | 10 + crates/tinyhivemind/src/lib.rs | 8 + crates/tinyhivemind/tests/public_api.rs | 18 +- docs/specs/approval.md | 2 +- 16 files changed, 1546 insertions(+), 4 deletions(-) create mode 100644 crates/tinyhivemind-core/src/approval/README.md create mode 100644 crates/tinyhivemind-core/src/approval/mod.rs create mode 100644 crates/tinyhivemind-core/src/approval/test.rs create mode 100644 crates/tinyhivemind-core/src/approval/types.rs create mode 100644 crates/tinyhivemind/src/approval/README.md create mode 100644 crates/tinyhivemind/src/approval/mod.rs create mode 100644 crates/tinyhivemind/src/approval/test.rs create mode 100644 crates/tinyhivemind/src/approval/types.rs diff --git a/crates/tinyhivemind-core/src/README.md b/crates/tinyhivemind-core/src/README.md index 19f84c8a..3f608292 100644 --- a/crates/tinyhivemind-core/src/README.md +++ b/crates/tinyhivemind-core/src/README.md @@ -8,6 +8,7 @@ README. | module | question it answers | | --- | --- | | [`aside`](aside/README.md) | how a private, off-transcript note is scoped to the readers it names | +| [`approval`](approval/README.md) | whether one typed side-effecting action is allowed, denied, or must be put to one person | | [`chat`](chat/README.md) | which stored chat id names which conversation, and which four spellings mean the default desk | | [`desk`](desk/README.md) | what a desk is, and who is on it once the declared blueprint is merged with runtime overlays | | [`dispatch`](dispatch/README.md) | does one committed reply start a child turn, and for whom | diff --git a/crates/tinyhivemind-core/src/approval/README.md b/crates/tinyhivemind-core/src/approval/README.md new file mode 100644 index 00000000..efceda87 --- /dev/null +++ b/crates/tinyhivemind-core/src/approval/README.md @@ -0,0 +1,7 @@ +# Approval module + +Approval is a total pure fold over a request, policy, grants, refusals, roster, +desks, and a host-supplied monotonic time.
