jentic-one AGENTS.md

jentic-one AGENTS.md is an instructions file for Codex, OpenCode from jentic/jentic-one. It costs 1,322 tokens per session, scanned C, original, Apache-2.0.

Repository guidance for using Jentic One, a tool that connects coding agents with external services and workflows. It also explains how to follow the project's local rules and how to report issues without changing code.

In plain words
What is it for?
Use it to install or connect an agent to Jentic One, check repository-specific instructions, run the tool on a separate machine, or file an issue while leaving the code unchanged.
Why use it?
It provides safe installation and operating instructions, including where the tool should run and how to verify a downloaded release.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

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.

Security

Grade C, and why

jentic-one AGENTS.md scanned grade C with 2 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 4d 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.

Using Jentic One (not changing it)

If your task is to install Jentic One and connect an agent to it, follow this section. The rest of this file is for changing the codebase.

Install. Two supported paths:

  1. Signed release binary, from https://github.com/jentic/jentic-one/releases/latest. Verify against checksums.txt (signature: checksums.txt.sig, certificate: checksums.txt.pem), then run jenticctl install. Prefer this path: it is verifiable before execution, and a sandboxed agent will usually be refused permission to pipe a script to a shell.
  2. Bootstrap script: curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh This downloads a Go toolchain if none is present, clones this repository, builds jenticctl and jentic, then runs jenticctl install. Set JENTIC_NO_INSTALL=1 to stop after the binaries are installed — do that on the agent machine, which needs only the binaries, not a second deployment.

Run Jentic One on a different machine from the agent. An agent running as the same OS user can read the credential database and encryption key from disk, whatever the API-level controls allow. See docs/security/hardening.md before using real credentials.

Register and reach a first call:

  1. jentic setup --url <control-plane URL> creates the agent identity, waits for an operator to approve it, and installs the agent skill. (jentic register --url … is the registration-only path — identity only, no skills; without --url both fall back to the configured base URL or http://127.0.0.1:8000, and prompt for it on an interactive terminal.) Report the wait to the user: on a single-operator install they are the operator, and they approve the agent in the UI at /app.
  2. If no admin account exists yet, point the user to /setup (browser) or jenticctl setup (terminal). This is a one-time step.
  3. Import an API from https://github.com/jentic/jentic-public-apis (e.g. httpbin.org, used in step 6), or register a private OpenAPI description of the user's own service.
  4. Store a credential for that API, once. It is encrypted at rest and is never returned.
  5. Request access: jentic access request --toolkit <vendor/name> files a reviewable request; granting is always a human action. The operator binds the agent to a toolkit — access is default-deny, and a rule-less binding still blocks everything.
  6. jentic execute GET:https://httpbin.org/get --json runs a call through the Broker with the credential injected. Give execute the operation's full upstream URL (as returned by jentic search/jentic inspect) or its operation_id — the Broker is a forward proxy, not a path router.

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.

jentic-one AGENTS.md is an instructions file published in the GitHub repository jentic/jentic-one (173 stars, last pushed 6d ago), licensed Apache-2.0. It adds 1,322 tokens to every session, about $0.0066 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
