Use Secnd with coding agents
Point Claude Code, Codex or Cursor at the Secnd docs and skill.
Until launch, API access is by request: request access. The console at console.secndai.com is not open yet.
A coding agent writes a correct Secnd integration when it reads the contract before it writes code. These docs publish plain-text files for agents:
- llms.txt: an index of every page, each linked as Markdown.
- llms-full.txt: every page in one Markdown file.
- skill.md: the Secnd skill, a short guide to calling
POST /v1/decide.
Any page is also available as Markdown: add .md to its URL, for example https://docs.secndai.com/quickstart.md.
Copy the agent prompt
Paste this at the start of a task that touches the Secnd API:
I am integrating the Secnd decision API (Ren 1.1) into this project.
1. Read https://docs.secndai.com/llms.txt first, then the pages for the question type we need.
2. Call POST https://api.secndai.com/v1/decide from server code only. Read the key from the SECND_API_KEY environment variable.
3. Pin the model to ren-1.1.0 and send an explicit threshold.
4. Before any side effect, branch on "action": on "ask_human", send the case to human review; on "act", still enforce our permissions and business rules.
5. Handle errors by HTTP status and "code". If the call fails, never invent an answer.
Check every field name against https://docs.secndai.com/openapi.json instead of guessing.Install the Secnd skill
The skill is one SKILL.md file. It tells the agent when to use Secnd, how to ask a choice, score or true/false question, how to read probability and action, and where the docs are.
Claude Code
Save it as a project skill:
mkdir -p .claude/skills/secnd
curl -fsSL https://docs.secndai.com/skill.md -o .claude/skills/secnd/SKILL.mdUse ~/.claude/skills/secnd instead to make it available in every project. Claude Code loads the skill when a task matches its description, and /secnd runs it directly.
Codex, Cursor and other agents
Add this line to the instructions file your agent reads, such as AGENTS.md:
Before writing code that uses the Secnd API, read https://docs.secndai.com/llms.txt and https://docs.secndai.com/skill.md.Review what the agent writes
Check the generated code for the same things you would check by hand:
- The API key stays on the server and out of logs.
- True/false questions use
"type": "noul", withoutoptionsorlevels. - Every side effect waits for
action, andask_humanreaches a person. See escalate to a human. - Failed calls are retried within a bounded budget and never turned into an answer. See errors.
