openstoryline-installInstalls, repairs and starts a local source checkout of FireRed-OpenStoryline, from prerequisites and a venv to resources, config and the MCP and web servers.
The agent keeps the workflow deterministic: confirm the repo path and read README.md and config.toml, detect prerequisites before changing anything, prefer a local venv unless you ask for Docker or conda, download resources only after the Python dependencies succeed, and validate imports and config loading before reporting success. It assumes macOS, Linux or WSL with a POSIX shell.
Prerequisites are git, Python 3.11 or newer, ffmpeg, wget and unzip, with Docker and conda optional. Missing tools are installed through the OS package manager (Homebrew and apt examples are given), and the agent stops and reports the gap if that is not possible. For the interpreter it prefers an existing system, conda or pyenv Python at 3.11 or newer after a standard-library check, falls back to a new conda environment, and always creates a repo-local .venv for install, config validation and service startup.
The scope also includes cloning the repository, downloading the .storyline models and resource assets, filling model settings in config.toml, starting the MCP and web servers, and explaining common gaps in the install documentation. The excerpt is cut off in the install commands.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit c9e9452. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
pythoncondaapt-getbrewbashpipFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
REPLACE_WITH_REAL_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
OpenStoryline Install Helper loads about 1.5k tokens when it runs. Until then it costs about 110 tokens; SKILL.md has 550 words of instructions outside code blocks.
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.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
sudo apt-get updatesudo apt-get install -y ffmpeg wget unzipAutomated 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.

.claude/skills/openstoryline-install/SKILL.md (or your agent's skills folder).Use this skill when the task is to install or repair a local source checkout of FireRed-OpenStoryline.
Keep the workflow deterministic:
venv install unless the user explicitly asks for Docker or conda..storyline models and resource/ assetsconfig.toml model settingsCheck these first:
git>= 3.11ffmpegwgetunzipOptional:
dockercondaIf ffmpeg, wget, or unzip are missing, install them through the OS package manager before continuing.
Examples:
macOS with Homebrew:
brew install ffmpeg wget unzipDebian/Ubuntu:
sudo apt-get update
sudo apt-get install -y ffmpeg wget unzipIf no supported package manager or permission is available, stop and report the missing system dependency clearly.
First prefer any interpreter that already exists and passes version checks:
>= 3.11>= 3.11>= 3.11, but only if basic stdlib modules workValidate candidate interpreters before using them:
/path/to/python -c "import ssl, sqlite3, venv; print('stdlib_ok')"If no supported interpreter already exists, peferr conda fallback:
conda create -y -n openstoryline-py311 python=3.11
conda run -n openstoryline-py311 python --version
conda run -n openstoryline-py311 python -m venv .venvAfter a supported interpreter is found, always create a repo-local .venv and continue using .venv/bin/python for install, config validation, and service startup.
Do not duplicate the rest of the workflow for pyenv or conda unless the user explicitly asks to stay inside a conda environment.
From the repo root:
/path/to/python -m venv .venv
.venv/bin/python -m pip install --upgrade pip
.venv/bin/python -m pip install -r requirements.txt
bash download.shNotes:
download.sh pulls both model weights and a large resource archive. It can take a long time and may resume after network drops.Before starting the app, update config.toml.
You can use scripts/update_config.py.
At minimum, fill:
.venv/bin/python scripts/update_config.py --config ./config.toml --set llm.model=REPLACE_WITH_REAL_MODEL
.venv/bin/python scripts/update_config.py --config ./config.toml --set llm.base_url=REPLACE_WITH_REAL_URL
.venv/bin/python scripts/update_config.py --config ./config.toml --set llm.api_key=sk-REPLACE_WITH_REAL_KEY
.venv/bin/python scripts/update_config.py --config ./config.toml --set vlm.model=REPLACE_WITH_REAL_MODEL
.venv/bin/python scripts/update_config.py --config ./config.toml --set vlm.base_url=REPLACE_WITH_REAL_URL
.venv/bin/python scripts/update_config.py --config ./config.toml --set vlm.api_key=sk-REPLACE_WITH_REAL_KEYOptional but common:
search_media.pexels_api_key for searching mediagenerate_voiceover.providers.* (choose one provider)Run these checks before saying installation is complete:
.venv/bin/pip check
PYTHONPATH=src .venv/bin/python -c "from open_storyline.config import load_settings; load_settings('config.toml'); print('config_ok')"Also confirm key resources exist:
test -f .storyline/models/transnetv2-pytorch-weights.pth
test -d resource/bgmsThere are two common paths. These are long-running processes. Do not wait for them to exit normally. Treat successful startup log lines or confirmed listening ports as success, and keep the services running in separate shells/sessions as needed.
Manual start:
PYTHONPATH=src .venv/bin/python -m open_storyline.mcp.serverIn a second shell:
PYTHONPATH=src .venv/bin/python -m uvicorn agent_fastapi:app --host 127.0.0.1 --port 8005After a successful install:

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add FireRedTeam/FireRed-OpenStoryline --skill openstoryline-install -a cursor` (or -a gemini-cli, github-copilot or opencode for the others).

Going by SKILL.md and its folder, OpenStoryline Install Helper needs the command-line tools its instructions call (python, conda, apt-get, brew, bash and pip) and credentials named REPLACE_WITH_REAL_KEY. Our summary lists: git, Python 3.11 or newer, ffmpeg, wget and unzip; macOS, Linux or WSL with a POSIX shell; API keys for the models set in config.toml.
SKILL.md contains no URLs. Its commands use pip, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (runs commands with sudo), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
OpenStoryline Install Helper is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 6.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
