parkinsons-law

parkinsons-law is a skill for Claude Code, Codex from The-Artificer-of-Ciphers-LLC/skills-from-the-artificer. It costs 105 tokens per session (818 once invoked), scanned A, original, MIT.

A planning principle saying that work tends to expand until it fills the time allowed for it.

In plain words
What is it for?
Use it when setting deadlines, planning projects or sprints, limiting scope, and discussing why teams rarely finish early.
Why use it?
It explains why projects often use an entire sprint or deadline, even when the original task seemed smaller. Extra time can turn into added scope, polishing, or second-guessing.

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

parkinsons-law 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 12d 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.

Parkinson's Law

"Work expands so as to fill the time available for its completion." — Cyril Parkinson, 1955

The core idea

Given more time to complete a task, people use it — through more elaborate solutions, more polishing, more scope, more second-guessing, or simply slower pace. The work doesn't have a fixed duration; it stretches to fill whatever container you give it.

Parkinson observed this originally in bureaucracies (a report that could be done in one day takes three when three are allocated), but the pattern is universal in knowledge work.

Why it happens

Effort adjusts to perceived time available. If you have a week, you approach a problem as a week-long problem. If you have a day, you find the 80% solution that matters.

Scope expands with available time. Extra time rarely stays empty — people find adjacent improvements, additional polish, more edge cases to handle, more documentation to write. This isn't laziness; it's often genuine value-adding activity. But the result is that the task always ends up using the time.

Perfectionism is proportional to deadline pressure. "Good enough" requires a definition of "good." When there's abundant time, "good enough" ratchets upward.

Meetings expand too. A meeting scheduled for an hour takes an hour. The same discussion, if you must resolve it in 30 minutes, usually resolves in 30 minutes.

How to use this for good

Set tighter deadlines intentionally. When you want a decision made, a design drafted, or a prototype built, giving less time forces prioritization. Parkinson's Law is a productivity tool when you use it deliberately.

Time-box rather than scope-box. Instead of "deliver feature X completely," try "spend two weeks on X and ship whatever is done." Time-boxing forces prioritization within the available time.

Use short sprints. Two-week sprints create more focus and delivery rhythm than month-long ones. Shorter cycles mean more frequent accountability and less opportunity for scope drift.

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.
