What it does

Liveserver is an agent skill from mathiasertl/django-ca. Start a local Django development server and make HTTP requests against it for interactive endpoint testing

Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `liveserver_settings.py`).

It sits in Backend & APIs, covering Backend development, Cryptography and API testing. It works with Django and Python. The repository describes itself as: A TLS certificate authority with CRL, OCSP, HSM and ACMEv2 support and more. The licence is GPL-3.0.

When your agent uses it

Tasks that involve Backend development
Tasks that involve Cryptography
Tasks that involve API testing

Example prompts

“/liveserver”

Requirements

Python 3

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

GET the target page (e.g. /admin/login/) and extract the csrftoken cookie value.
Include it as both the X-CSRFToken header and the csrfmiddlewaretoken form field on all POST/PUT/DELETE requests.

What it can do on your machine

Read from SKILL.md and the folder at commit feabb70. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
- uv
- curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv and curl, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Liveserver loads about 977 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 278 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~29
When it runs · the whole SKILL.md, loaded when a task matches: ~977

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: liveserver
description: Start a local Django development server and make HTTP requests against it for interactive endpoint testing

Overview

The live server uses liveserver_settings.py (located alongside this file in .opencode/skills/liveserver/) and runs on http://127.0.0.1:8001. All commands below must be run from the repo root.

The settings file is loaded by adding its directory to PYTHONPATH at invocation time:

bash

PYTHONPATH=.opencode/skills/liveserver DJANGO_SETTINGS_MODULE=liveserver_settings

It provides a persistent SQLite database and real CA file storage — independent of the test suite.

CA_USE_CELERY = False so all tasks (CRL generation, OCSP key creation, etc.) run synchronously in-process — no Celery worker is needed.

Initial setup (first time only, or after deleting the database)

bash

# Create the CA files directory
mkdir -p ca/liveserver_files

# Apply migrations to create the local SQLite database
PYTHONPATH=.opencode/skills/liveserver DJANGO_SETTINGS_MODULE=liveserver_settings \
    uv run python ca/manage.py migrate

# Create a superuser for admin access
PYTHONPATH=.opencode/skills/liveserver DJANGO_SETTINGS_MODULE=liveserver_settings \
    uv run python ca/manage.py createsuperuser

Starting the server

First, check whether it is already running:

bash

curl -s -o /dev/null -w "%{http_code}" http://127.0.0.1:8001/django_ca/ 2>/dev/null

If that returns 301 or 200, the server is already up — skip starting it.

Otherwise, start it in the background:

bash

PYTHONPATH=.opencode/skills/liveserver DJANGO_SETTINGS_MODULE=liveserver_settings \
    uv run python ca/manage.py runserver 127.0.0.1:8001 \
    > .opencode/skills/liveserver/liveserver.log 2>&1 &
echo $! > .opencode/skills/liveserver/liveserver.pid
sleep 2  # wait for startup

Verify it started successfully:

bash

curl -s -o /dev/null -w "%{http_code}" http://127.0.0.1:8001/django_ca/

Check logs if something looks wrong:

bash

cat .opencode/skills/liveserver/liveserver.log

Making HTTP requests

Use the FetchMCP tool for all requests. The base URL is http://127.0.0.1:8001.

Key URLs

Endpoint	URL
Admin interface	`http://127.0.0.1:8001/admin/`
REST API root	`http://127.0.0.1:8001/django_ca/api/`
ACME directory	`http://127.0.0.1:8001/django_ca/acme/directory/`
CRL (per CA)	`http://127.0.0.1:8001/django_ca/crl/<serial>/`
OCSP (per CA)	`http://127.0.0.1:8001/django_ca/ocsp/<serial>/`

Authentication

Admin / session-based views: POST to /admin/login/ with username, password, and csrfmiddlewaretoken. Retrieve the CSRF token first with a GET to the login page (look for csrfmiddlewaretoken in the HTML or csrftoken cookie).
REST API: The API uses session auth by default. Log in via admin first and reuse the session cookie, or check CA_ENABLE_REST_API endpoints for token auth options.
OCSP / CRL: No authentication needed — these are public endpoints.

CSRF for POST requests

GET the target page (e.g. /admin/login/) and extract the csrftoken cookie value.
Include it as both the X-CSRFToken header and the csrfmiddlewaretoken form field on all POST/PUT/DELETE requests.

Stopping the server

bash

kill "$(cat .opencode/skills/liveserver/liveserver.pid)" 2>/dev/null \
    || pkill -f "manage.py runserver 127.0.0.1:8001"
rm -f .opencode/skills/liveserver/liveserver.pid

Resetting state

To start fresh (wipe DB and CA files):

bash

rm -f ca/liveserver.sqlite3
rm -rf ca/liveserver_files/
mkdir -p ca/liveserver_files
PYTHONPATH=.opencode/skills/liveserver DJANGO_SETTINGS_MODULE=liveserver_settings \
    uv run python ca/manage.py migrate
PYTHONPATH=.opencode/skills/liveserver DJANGO_SETTINGS_MODULE=liveserver_settings \
    uv run python ca/manage.py createsuperuser
