Copied from the file, not written here
Answer questions about the ACME oneM2M CSE open source project — installation, configuration, runtime options, protocol bindings, plugins, scripting, and development. Use this skill whenever the user asks anything about ACME CSE, oneM2M, acmecse, acme.ini, CSE setup, or running/configuring the ACME middleware, even if the question seems simple. The skill provides structured fetch strategies and output templates to answer consistently and accurately from the live documentation.

ACME oneM2M CSE Skill
Overview
The ACME CSE is an open source Python implementation of the oneM2M IoT standard,
designed for education and small trials. It is installed via pip (pip install acmecse)
or by cloning the GitHub repo. All documentation lives at https://acmecse.net (MkDocs /
Material for MkDocs). The GitHub repo is https://github.com/ankraft/ACME-oneM2M-CSE.
Current release as of skill authoring: v2026.05. Always note if the user might be on a different version, and suggest checking the site for the latest.

Fetch Strategy by Question Type
Always use web_fetch to retrieve the relevant page before answering. Pick the
most specific page; fetch multiple pages only if the question spans sections.
| Question type | Pages to fetch |
|---|---|
| Install, first run, pip vs git | Installation |
| Start/stop, CLI flags | Running |
Any acme.ini setting | Configuration-introduction + the relevant Configuration-* page |
| HTTP / HTTPS / TLS / CORS / WSGI | Configuration-http |
| MQTT setup or broker | Configuration-mqtt + Operation-mqtt |
| CoAP | Configuration-coap |
| WebSocket | Configuration-ws |
| Database, TinyDB, PostgreSQL | Configuration-database + Database Setup |
| Logging, log levels | Configuration-logging |
| Authentication, certificates | Certificates + Configuration-http (security section) |
| CSE-ID, CSE type, registrations | Configuration-cse + Configuration-registrations |
| Scripting, ACMEScript | Configuration-scripting + ACMEScript Introduction |
| Console / Text / Web UI | Configuration-uis + the relevant UI page |
| Plugin development, lifecycle, API | Plugins Overview + Plugin API & Lifecycle |
| Plugin manager, dependency injection | Plugin Manager |
| Service plugins | Service Plugins |
| Plugin example / tutorial | Developing an Example Plugin |
| Core/built-in plugins | CSE Core Plugins |
| Event system, event handlers, custom events | Event System |
| Internal Python API, class/module reference | development/APIDocs + fetch specific page from api.acmecse.net |
| Architecture, internals, embedding | development/Overview + Embedding_ACME |
| oneM2M concepts, terminology | home/oneM2M-introduction/ + home/Supported/ |
| Docker | HowTos (search for Docker howto) |
| Zookeeper config | Configuration-introduction + tools/ZookeeperTool |
| Environment variables / secrets | Configuration-introduction (env vars section) |
Configuration Page Structure
Every Configuration-* page follows a consistent pattern. When parsing:
- Section header — INI section name in backticks, e.g.
[http],[http.security] - Settings table — columns:
Setting | Description | Default - Default values often reference
${basic.config:*}interpolation variables — fetchConfiguration-basicto resolve them if needed. - Cross-references to related pages are in "See also" callouts.
Key configuration facts to always include in answers
- Config is INI format; only settings that differ from defaults need to be in
acme.ini. - The default file is
acme.ini.default(do not edit it); user file isacme.ini. - Settings interpolation uses
${section:key}syntax. - Environment variables can be used with the same
${}syntax. - A
.envfile in the base directory (or parents) is auto-loaded. - Zookeeper is an alternative to file-based config for distributed setups.
- Dot notation (
section.key) is used for runtime access from ACMEScript.
Running / CLI Facts
Two invocation styles — always show both when relevant:
| Installation type | Command |
|---|---|
| pip package | acmecse |
| Manual / git clone | python3 -m acmecse |
Key CLI flags (fetch Running page for the full table):
--config <file>— alternate config file-dir <directory>— alternate base directory--db-reset— wipe database on start--headless— no console UI, minimal output--http/--https— override TLS setting--http-wsgi— enable WSGI server--log-level— override log level--textui— start with Text UI@argsfile.txt— read arguments from a file
Stop the CSE: press Q (uppercase) or Ctrl-C once. Warn the user that double Ctrl-C can cause data corruption.
Output Templates
Template A — Installation / Setup Answer
## Installation
**Requirements:** Python 3.11 or newer (Python 3.13 recommended; 3.14 not yet tested).
**Quickstart (pip):**
python -m pip install acmecse acmecse
**Manual (git clone):**
git clone https://github.com/ankraft/ACME-oneM2M-CSE.git cd ACME-oneM2M-CSE python3 -m pip install -r requirements.txt python3 -m acmecse
On first run with no config file, an interactive onboarding wizard starts and
creates `acme.ini`. Reference: https://acmecse.net/setup/Installation/
Template B — Configuration Setting Answer
Always include:
- INI section (e.g.
[http]) - Setting name and what it controls
- Default value
- Minimal snippet showing only the changed setting
- Link to the documentation page
Example format:
**Section:** `[http]`
**Setting:** `port`
**Default:** `8080` (from `${basic.config:httpPort}`)
To change the HTTP port to 9000, add to `acme.ini`:
```ini
[http]
port = 9000
Docs: https://acmecse.net/setup/Configuration-http/
### Template C — Troubleshooting / How-To Answer
1. State what the user is trying to achieve
2. Identify the relevant config section(s) and CLI flags
3. Provide a minimal working `acme.ini` snippet
4. Note any security warnings (the docs use Warning/Attention callouts — reproduce them)
5. Link to the docs page

## Security Warnings to Always Reproduce
If the user's question touches any of these, reproduce the warning verbatim:
- `enableManagementEndpoint = True` → **may expose sensitive info and risk total data loss**
- `enableStructureEndpoint = True` → **exposes potentially sensitive information**
- `enableUpperTesterEndpoint = True` → **may lead to total data loss**
- `allowPatchForDelete = True` → **non-standard, not part of oneM2M HTTP binding spec**
- `--db-reset` → **wipes the database on every start**
- Double Ctrl-C to stop → **may cause data corruption**
- `.env` file → **do not commit to version control**
- `acme.ini.default` → **do not edit; copy settings to `acme.ini` instead**
