deep-work

deep-work is a skill for Claude Code, Codex from deciqAI/knowledge-skills. It costs 123 tokens per session (1,874 once invoked), scanned A, original, MIT.

A framework for protecting uninterrupted time for difficult thinking and creative work. It distinguishes deep work, which requires concentration, from shallow work such as routine messages and administration.

In plain words
What is it for?
Use it to plan focused periods for research, writing, engineering, design, or strategy. It can also help structure deliberate practice and connect important work to goals.
Why use it?
It helps explain why busy schedules can still produce little meaningful progress. It also accounts for the time needed to regain focus after interruptions.

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

deep-work 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 4d 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.

Deep Work

Overview

Cal Newport's framework (2016): deep work = undistracted, cognitively demanding activity that creates hard-to-replicate value; shallow work = logistical, responsive, easy-to-replicate work that fills modern calendars. The most valuable knowledge work is disproportionately the product of deep work; shallow work is increasingly automatable. Three foundations: attention research shows 15-25 min recovery cost per interruption; expert performance requires deliberate practice (structurally a form of deep work); the opportunity cost of shallow work is invisible — no one tracks which deep work didn't happen this week.

Composes with wu-wei (flow as the felt experience), metacognition (monitoring drift out of deep mode), okr-goal-setting (OKRs give deep work direction), pareto-principle (the 20% producing 80% of value is almost always deep work).

When to Use

  • Output depends on hard-to-replicate cognitive work (research, engineering, writing, design, strategy)
  • Calendar fragmentation prevents the work that actually matters; weeks feel busy but produce nothing
  • High-stakes project requires extended concentration; career advancement depends on skill development
  • AI copilots / assistants have become another interruption stream ("is AI helping my focus or fragmenting it?", "AI adoption vs deep work", "AI hype and staying focused")

Not when: genuinely high-coordination roles where deep work is structurally impossible; already done with deep work and shallow follow-through is now required; short-term emergency where availability dominates.

Coaching Novices (Adaptive Front Door)

  • Engine mode: user has a concrete case → run The Process directly.
  • Coach mode: user unfamiliar or has no concrete case → guide step by step.

In Coach mode, respond one step at a time. Each [WAIT] is a hard stop — output only that step's question, then stop.

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.

deep-work is a skill published in the GitHub repository deciqAI/knowledge-skills (10 stars, last pushed 2d ago), licensed MIT. It adds 123 tokens to every session and 1,874 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
