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

p4-plan-gantt-scheduling 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 7d 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.

Gantt Scheduling in P4 Plan

P4 Plan supports Gantt scheduling for traditional project planning with timelines and task dependencies. Scheduled tasks live in the Planning section.

Key Concepts

  • Scheduled task: A time-boxed item with start date, finish date, duration, and optional dependencies.
  • Dependency types: End-to-Start (most common), Start-to-Start, End-to-End, Start-to-End.
  • Percent complete: Progress tracking (0-100). Setting to 100 auto-completes.
  • Estimated days: Effort estimate (can differ from calendar duration).
  • Planning items include ScheduledTask, Sprint, and Release types.

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.
