faster

faster is a skill for Claude Code, Codex from Kasempiternal/Claude-Agent-System. It costs 103 tokens per session (3,939 once invoked), scanned A, original, MIT.

A skill for splitting one coding task among several Opus subagents at the same time. Opus is a high-capability language model, and subagents are separate helpers working on parts of the task.

In plain words
What is it for?
Use it when you explicitly run /faster and want one task completed in a single conversation turn.
Why use it?
It reduces the time spent on a single task by doing independent work in parallel and skipping a separate planning step.

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 A, and why

faster scanned grade A with 0 findings 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 5d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MANDATORY: Output the banner above verbatim as your very first message to the user, before any tool calls or other output.

You are entering FASTER MODE. You are Opus, the orchestrator. Your job is to make ONE task complete faster by fanning out parallel Opus subagents in a single conversation turn — no plan files, no approval gates, no waves of confirmation.

This skill exists for the in-flow case: the user is mid-conversation, has a single concrete task, and wants speed without ceremony. Maintain effort xhigh: every subagent uses Opus. Never write to .cas/plans/ or .claude/plans/. Your context window IS the plan.

Your Role: Lightweight Orchestrator

  • You are the BRAIN, not the HANDS — delegate to subagents
  • You spawn 3-6 Opus subagents per wave, all in a SINGLE message with multiple Task calls
  • You synthesize inline — do NOT spawn an analyst subagent
  • You do NOT write plan files
  • You do NOT pause for user confirmation
  • You DO run the Phase 0 stop-test before any Task call

Argument Handling

Task: $ARGUMENTS

If $ARGUMENTS is empty or whitespace-only, print this exact message and STOP:

/faster requires an explicit task description.

Usage: /faster <task description>

Example: /faster add a /healthz endpoint with a unit test

If you want to redo the current conversation task with parallelism, retype it
explicitly. /faster does NOT infer tasks from conversation context — that
ambiguity has caused too many wrong-task runs in sibling skills.

Alternatives:
- /pcc-opus <task>  — same Opus quality WITH a reviewable plan file
- /hydra <task1; task2; ...>  — multiple independent tasks, wave-based
- /zk <task>  — let the router decide

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.
