Nexent is a zero-code platform for creating AI agents from natural-language instructions, combining tools, skills, memory, orchestration, constraints, feedback loops, and control planes. It is intended for people who need to build and deploy agents without writing orchestration code. The catalogue entries are rules and skills for working with Nexent.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01519 | $0.01519 |
| Opus 5.5 | $0.00608 | $0.00608 |
| Sonnet 5.5 | $0.00304 | $0.00304 |
| Haiku 4.5 | $0.00152 | $0.00152 |
Grade A, and why
nexent AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts

Shared constraints
- Write code comments, docstrings, TODOs, and configuration comments in English. User-facing strings may use supported languages; this does not prescribe conversation language.
- Every new or modified source file (
.py,.sh,.sql,.ts,.tsx,.js,.jsx,.mjs) must start with the copyright headerCopyright (c) 2025-2026 Huawei Technologies Co., Ltd. All rights reserved.(the end year tracks the current year, e.g.2025-2027in 2027) in the file's comment style (#for Python/Shell,--for SQL,//for TypeScript/JavaScript), placed after shebang/encoding lines. TheCopyright Header CheckCI job rejects changed files missing it; verify or fix locally withpython scripts/check_copyright.py [--fix] <files...>. - In backend/SDK Python code, centralize environment reads in
backend/contracts/constants/environment.py. Backend callers import fromcontracts.constants.environment; SDK code accepts parameters and must not read environment variables or introducefrom_env()methods. - Every SQL file under
deploy/sql/already merged into the target branch is immutable, including initialization and Supabase SQL. Do not edit, rename, or delete it. Add versioned migrations underdeploy/sql/migrations/; application version isAPP_VERSIONinbackend/contracts/constants/environment.py. - Preserve existing HTTP routes, payloads, and response contracts when applying conventions to new code.
Load rules for the task
Before editing or reviewing these areas, read the linked skill and only its applicable references. Paths are relative to this root. Read files directly if the client has no skill loader; no package download is required. For cross-layer work, load each relevant skill. Documentation-only work does not require unrelated coding skills.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
