ccc-night-mode

ccc-night-mode is a skill for Claude Code from KevinZai/commander. It costs 47 tokens per session (1,458 once invoked), scanned C, original, MIT.

An unattended coding workflow that plans a task, then builds it immediately or on a scheduled overnight run. It can also watch builds and tests while work continues.

In plain words
What is it for?
Use it to prepare and run overnight builds, start autonomous work immediately, or monitor CI, builds, tests, dependencies, and pull requests.
Why use it?
It removes the need to stay at the computer and approve every step during long coding jobs.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; names the AskUserQuestion tool; positional $N argument.

Not installable on its own: it reads a path above its own folder, which only exists inside its repository. The line is Placeholders like ~~project tracker refer to connected tools. See [CONNECTORS.md](../../CONNECTORS.md)..

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

ccc-night-mode scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

$ccc-night-mode — Autonomous overnight build

Placeholders like ~~project tracker refer to connected tools. See CONNECTORS.md.

Autonomous build system for unattended work. Two modes: Night Mode (spec now, build overnight, 8-hour scheduled run) and YOLO Mode (spec now, build immediately, no confirmations). Full menu in references/autonomous-mode.json.

Quick Mode (default)

Ask the user which mode via AskUserQuestion:

  • Night Mode — scheduled overnight run, starts building when you close your laptop
  • YOLO Mode — starts immediately, no confirmations, maximum autonomy
  • Monitor & Maintain — watch CI, fix builds, guard tests (recurring loop)
  • Cancel / Back to main menu

Then proceed to the 10-question Spec Interview.

Power Mode

Full autonomous mode menu from references/autonomous-mode.json. Activate by passing --power or detailed. Includes:

  • Monitor & Maintain (PR Babysitter, Build Shepherd, Test Guardian, PR Pruner, Dependency Watcher, Cost Monitor)
  • Background Coding (implement from spec, post-merge sweep, doc updater, knowledge compounder)
  • Batch Operations (CJS→ESM, class→hooks, multi-file rename, dependency upgrade, lint rule enforcement)
  • Custom Loop (describe what + how often)

Spec Interview (10 Questions — ALL required before autonomous execution)

Ask every question. Do not skip or assume.

  1. What are you building? — Full project description
  2. Who is it for? — Target users/audience
  3. Most critical feature? — The one thing that MUST work
  4. Tech stack? — Languages, frameworks, databases, infrastructure
  5. What does DONE look like? — Specific acceptance criteria
  6. What does BROKEN look like? — Failure modes to prevent
  7. Edge cases? — Known tricky scenarios to handle
  8. Testing requirements? — Unit, integration, E2E expectations
  9. Deployment target? — Where it runs (Vercel, AWS, Docker, local)
  10. Anything else? — Additional context, constraints, API keys needed

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ccc-night-mode is a skill published in the GitHub repository KevinZai/commander (6 stars, last pushed yesterday), licensed MIT. It adds 47 tokens to every session and 1,458 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
