+
+> [!WARNING]
+> ### ⚠️ Provenance: not an original dataset
+>
+> **FastBrain-Instruct is NOT written from scratch.** It aggregates existing open datasets, reformats them into one choice/routing schema, removes finance content, deduplicates, and decontaminates against public decision benchmarks. All query text and labels come from the upstream sources below (except 25 maintainer-written DevOps templates).

+
+## 📌 What it is
+
+Each row is a single decision: given a `query` (a user request, or for agent rows the recent conversation) and a list of candidate `choices` (name + description), pick the correct `target`. The format targets non-autoregressive "System 1" decision heads (e.g., the `JointSchemaHead` design used by Cloudflare Clef / Clef-Flash) that score candidates in one forward pass.
+
+Two domains, balanced 50/50:
+- **`code_mechanical`** — tool / function selection (Glaive, Hermes), multi-tool agent next-tool selection (Nemotron), terminal utility selection (NL2Bash), git subcommand selection, DevOps templates.
+- **`daily_assistant`** — intent selection for voice-assistant and service dialogues (MASSIVE, SGD).
+
+No model trained on this dataset is released, and no benchmark results are claimed.
+
+## 🚫 Benchmark exclusion & decontamination
+
+This dataset is intended for training models that will be compared on the benchmarks used in the Cloudflare Clef / Jev Decision Index table. Therefore:
+
+1. **No benchmark is used as a source.** Excluded entirely: BFCL, ToolRet and all 35 of its source datasets (incl. APIGen/xLAM, ToolACE, ToolBench, Gorilla, MetaTool, API-Bank, …), API-Bank, When2Call (and derived data such as the When2Call part of AgentToolDecisions), BANKING77, CLINC150, BRIGHT, Amazon ESCI, PhishNChips.
+2. **Text-level decontamination.** Every query (for agent rows: every user message) was checked against the texts of BFCL v3, ToolRet-Queries (35 subsets), When2Call (all files), API-Bank (all files), BANKING77 and CLINC150 (all configs). A row is removed on a normalized exact match **or** any shared 10-word n-gram. 2,674 rows were removed this way (e.g., Glaive: 899 ToolRet, 470 BFCL, 333 When2Call matches; SGD: 420 BFCL matches; MASSIVE: 212 CLINC150 matches).
+
+Not checked at text level: Home appliances (no public copy found), BRIGHT, Amazon ESCI, PhishNChips (different domains from all sources used).
+
+## 🔧 Processing
+
+1. **Extraction**
+   - Glaive v2: all 112,960 rows scanned; the user turn right before the first `<functioncall>` is the query; candidates are the tools listed in that sample's system prompt.
+   - Hermes v1: first human turn; candidates are that sample's tools.
+   - Nemotron agentic: conversation rendered as `role: content` lines (last 1,500 chars); candidates are all tools available to the agent (5–30).
+   - NL2Bash: only single, non-compound commands (no pipes, `;`, `&&`, substitutions, loops); target is the utility name; `find` capped at 1,500 rows.
+   - SGD: user turns where a service's active intent changes; candidates are the intents of that service plus intents from other services, with SGD's own intent descriptions.
+   - MASSIVE: all splits; description generated from the label name.
+2. **Candidates**: at least 5 per row; when a sample has fewer own candidates, random distractors from the same source are added, excluding names that heavily overlap with the target (token Jaccard ≥ 0.5).
+3. **Finance removal**: MASSIVE `qa_currency`, `qa_stock`; SGD `Banks_*` and `Payment_*` services.
+4. **Deduplication**: normalized exact `query` duplicates removed; queries with conflicting labels dropped (1,410).
+5. **Balancing**: the larger domain is downsampled (largest source first) to match the smaller one.
+6. **Split**: random 90/10 over unique queries; no `query` appears in both splits.
+
+## 📊 Statistics
+
+| | Train | Test | Total |
+| :--- | ---: | ---: | ---: |
+| **Rows** | **97,450** | **10,828** | **108,278** |
+| `code_mechanical` | — | — | 54,139 (50%) |
+| `daily_assistant` | — | — | 54,139 (50%) |
+| Choices per row | 5–30 (median 5) | | |
+| Distinct targets | | | 5,681 |
+
+## ⚠️ Limitations
+
+- **Easy distractors in some sources**: Glaive and NL2Bash rows usually have only one "own" candidate, so the other 4 are random and often unrelated.
+- **Near-duplicates remain**: templated queries (Glaive, SGD) differing only in entities are kept; only exact duplicates were removed.
+- **Weak descriptions**: MASSIVE descriptions are generated from label names (e.g., "User intention to play music"); Nemotron tool descriptions are kept as-is.
+- **NL2Bash skew**: `find` dominates the terminal subset even after capping.
+- **Decontamination is lexical**: paraphrased benchmark items would not be caught.
