6 core features

Every feature, built for real sessions.

Not hypothetical demos. Every feature here was built because a real Claude Code session went sideways and we needed it.

Real-Time Monitoring

Singularity polls Claude Code JSONL session files every second. New sessions are discovered automatically. See every file edit, command execution, and tool call as it happens in a live activity feed.

$ chmod -R 777 ./exit 1

Dangerous command: recursively sets all permissions to world-readable/writable/executable on the entire project. This exposes source code, credentials, and config files to any user on the system. Command was blocked before execution.

Terminal Intervention

Explains every CLI command in plain English, flags dangerous ones, and can block risky operations before they execute. Supports Terminal, iTerm2, Alacritty, Kitty, Warp, Hyper, WezTerm, and Ghostty.

Rules as Markdown

Write supervision rules in plain markdown. Import your CLAUDE.md or codex files directly. 7 built-in rules cover common failure modes. Add custom rules via the in-app editor.

# Rule: No unplanned refactoring
If the agent begins changing files not mentioned in the plan,
alert immediately. This includes renaming, restructuring, or
"improving" code that wasn't part of the task.
 
# Rule: Test before commit
The agent must run the test suite before any commit operation.
If tests fail, it should fix them before retrying the commit.
 
# Rule: Ask before deleting
Never delete files without explicit user confirmation.

Live Explainer

While the agent works, get plain-English explanations at your level — Junior (full explanations), Mid (non-obvious insights), or Senior (risks and trade-offs only).

Architecture

JWT vs Session Auth

The agent chose JWT for stateless authentication. This means tokens are self-contained and don't require server-side session storage, but they can't be invalidated server-side.

Patterns

Middleware Chain Pattern

Express middleware is being composed in a specific order: auth → rate-limit → validate → handler. Order matters because each layer can short-circuit the request...

CLI & Tools

Coverage threshold flag

--coverage flag enables Istanbul code coverage. The 80% threshold in jest.config.js means CI will fail if coverage drops below that.

Floating Pill

Always-on-top mini status indicator showing session name, progress bar, and alert count. Expands on click. Glows amber when alerts arrive.

Cross-Session Insights

Analytics dashboard showing session patterns, most violated rules, intervention effectiveness, and knowledge base search across all explainer entries.
