copilot-caas 0.2.0

Local Copilot as a Service wrapper with CLI and REST APIs.

copilot-service

copilot-service provides a stable local CLI and REST wrapper around Copilot/LLM CLI tooling so scripts and agents can call a normalized task API.

What problem this solves

Different LLM CLIs have different prompt formats and output styles. This project gives one stable contract for task-based calls (route-topic, freeform) and isolates provider setup in local config.

Releases

Automated releases are available through GitHub Actions. See docs/release.md for full instructions.

CLI UX

Running copilot-caas with no arguments shows a colorful welcome screen and exits 0:

copilot-caas

Check the installed version:

copilot-caas --version

Run a task:

copilot-caas ask --input examples/route-topic-request.json

Colors are automatically disabled when NO_COLOR is set or output is not a TTY.

Quickstart (fake provider)

python -m venv .venv
. .venv/bin/activate
pip install -e .

export COPILOT_SERVICE_PROVIDER=fake
export COPILOT_SERVICE_FAKE_RESPONSE='{"decision":"asr","confidence":0.8,"reason":"fake"}'
copilot-service ask --input examples/route-topic-request.json

Quickstart (shell provider)

export COPILOT_SERVICE_PROVIDER=shell
export COPILOT_SERVICE_SHELL_COMMAND='python -c "import sys; print(sys.stdin.read())"'
copilot-service ask --task freeform --prompt "Explain this"

REST usage

copilot-service serve --host 127.0.0.1 --port 8765

curl -sS http://127.0.0.1:8765/health
curl -sS http://127.0.0.1:8765/v1/ask \
  -H 'content-type: application/json' \
  --data @examples/freeform-request.json
curl -sS http://127.0.0.1:8765/v1/tasks/route-topic \
  -H 'content-type: application/json' \
  --data @examples/route-topic-request.json

Article-ingestion integration example

See examples/article-ingestion-usage.sh for a simple pipeline wrapper around the route-topic task.

Environment

• COPILOT_SERVICE_PROVIDER (shell for MVP, fake for tests)
• COPILOT_SERVICE_SHELL_COMMAND (provider command)
• COPILOT_SERVICE_MODEL (default gpt-5-mini)
• COPILOT_SERVICE_TIMEOUT_SECONDS (default 90)
• COPILOT_SERVICE_HOST (default 127.0.0.1)
• COPILOT_SERVICE_PORT (default 8765)

Limitations

• MVP ships only with shell/fake providers.
• Output quality depends on your configured local command and prompt discipline.
• route-topic fallback behavior can mask model errors when enabled (default true).

Security note

REST binds to 127.0.0.1 by default. The shell command is loaded only from local environment/config (never from request payload).
