It does not write prose. It takes a state plus questions whose answer space you define in advance, and returns typed values with probability distributions your code can branch on. | | | | ---------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Shape** | `state + typed questions` → `constrained answers + probabilities` → `your code` | | **Primitives** | `Choice` (pick one of ≤255 options), `Score` (a rubric 2–10), `Noul` (a probabilistic yes/no) | | **Endpoint** | `POST https://api.typesafe.ai/v1/systemone`, model `jev-1.13.0` / alias `jev-latest` | | **Good fits** | routing, triage, scoring, moderation, verification and low-latency gates inside a bounded workflow | | **Known limits** | counting is unreliable, multi-level indirection is weak, and official material names nine classes of jaggedness. Schema-valid output is not the same as a correct decision — calibrate on your own data. | ## How entries are graded Most lists in this space assert inclusion. This one says how much it actually verified, then lets you filter accordingly. | Grade | What it means | | ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------- | | `official` | Published by TypeSafe AI itself. | | `observed` | A public artifact that can be opened and read — real source, real configuration, or an explicit TypeSafe/Jev declaration in the repository name or topic. | | `inferred` | Matched on an ambiguous signal plus corroborating vocabulary, but not yet read line by line. | | `unverified` | Looks related, nothing independently confirmed. Listed for discovery only. | ## Official SDKs and developer tools Everything published by TypeSafe itself. Start here.

🎮 Xtags — X intent labeller · @tspy · 👁️ observed · 27d

##### 📝 Summary Xtags: a Chrome extension that labels each post in an X timeline with what it is trying to get from you — inducement, provocation, promotion, machine-generated, persuasion, entertainment, information — drawn as a tag plus a probability right after the timestamp. A side panel reports session counts (seen, judged, correct) and cumulative token cost. The author reports near-instant responses and usable accuracy before any tuning. ➡️ **Original project (manifoldor/xtags)** — [https://github.com/manifoldor/xtags](https://github.com/manifoldor/xtags) > 💡 Worth reading as a latency argument rather than an accuracy one: labelling a timeline only works if the decision costs less than the scroll, which is the constraint a generative model cannot meet. ##### 📌 Basic facts | Field | Value | | -------- | ----------------------------------------------------- | | Category | `Applications, games, robotics and interactive demos` | | Evidence | `observed` | | Owner | [yishan](https://x.com/tspy) · @tspy | ##### 📊 Data | Metric | Value | | ------------ | ---------- | | Views | **9873** | | Likes | 24 | | Comments | 11 | | Posted | 2026-09-18 | | First listed | 2026-09-18 | 🏷 `x` ---

TypeSafe **raw agree 90.8%** (2 of 8 questions flipped, but **conflicts=0**—the flips occurred only between "specific label ↔ uncertain"). **After adding an abstention rule (using `probabilities` to require top probability ≥ 0.60; otherwise `uncertain` routes to a human), agreement rose to 99.2%**, automatic 74.2%, **with no increase in model calls**. Comparison: Haiku t=0 100%, Opus 4.8 reasoning 92.5%, gpt-5.4-mini t=0 99.2%. Official statement: this does not make the model certain; these figures measure **repeatability, not correctness**; 0.60 is an example strategy, and production thresholds should be determined using labeled samples and costs. > 💡 **\[DEFINITION-CHANGE\]** Updated B5, the key figures table, SKILL.md hard rule 3 and launch item 6, and applicability boundary item 6—**this library previously recorded "non-determinism" as a risk; it is now changed to the official correct approach: manage it with abstention** ##### 📌 Basic facts | Field | Value | | -------- | ---------------------------------------- | | Category | `Writing, discussions and sibling lists` | | Evidence | `official` | ##### 📊 Data | Metric | Value | | ------------ | ---------- | | First listed | 2026-09-20 |

Infrastructure, documentation and discussion entries are excluded from this table.} ## Contributing Corrections are welcome and are the fastest way to improve this list. Open an issue or a pull request if an entry is misfiled, mis-graded, or if a project has been wrongly excluded as a name collision — that last category is where automated filters are most likely to be wrong. --- _{Independent community project.
