knowledge-layers

knowledge-layers is a skill for Claude Code from haowjy/creative-writing-skills. It costs 32 tokens per session (1,842 once invoked), scanned A, original, Apache-2.0.

A guide for deciding where project knowledge belongs: AGENTS.md, .context/, a knowledge base, docs/, or a temporary work folder. AGENTS.md gives directory-level guidance, while the other locations hold deeper, shared, user-facing, or temporary information.

In plain words
What is it for?
Use it when creating, editing, or reviewing project instructions, architecture notes, deferred work, shared decisions, user documentation, or temporary design notes.
Why use it?
It prevents instructions and decisions from being scattered in the wrong files. That makes durable project knowledge easier for coding agents and developers to find and maintain.

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

knowledge-layers 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Knowledge Layers

Load /creative-writing-skills:qi-layer when writing or editing AGENTS.md or .context/ files: it owns the craft (four principles, contents guidelines, what doesn't belong). Load /creative-writing-skills:information-hierarchy if not already loaded for disclosure tiers. Load /creative-writing-skills:llm-writing if not already loaded.

The Five Layers

Layer What it holds When to use it Reader
AGENTS.md Intent and mental model for a directory First thing agents read on entry; what to understand before working here An agent about to work in that directory
.context/ Contracts, architecture, rationale (CONTEXT.md); deferred work (TODO, FUTURE) Reference depth and tracked deferrals, co-located with the material they describe An agent about to edit that directory
KB Cross-cutting decisions, domain concepts, patterns Spans directories; outlives sessions; no single directory owns it A future agent or the owner, years on, without this work's context
docs/ User-facing documentation Different audience, different update cadence The product's user
Work directory Temporary design decisions and scratch Not colocated with durable content; scoped to an active work item Agents on this work item

Placement Rules

If it's intent/mental-model for a directory → AGENTS.md. If it's directory-scoped depth an agent looks up → .context/. If it's deferred work scoped to this directory → .context/TODO (must-do) or .context/FUTURE (nice-to-have). Flat markdown lists — each entry names the affected path and concrete follow-up. Cross-cutting items or items needing external visibility get filed in the project's issue tracker instead. If it's big picture — cross-cutting decisions, domain concepts, higher-level system architecture → KB. If it's for end users → docs/. If it's the human correcting an agent → the KB corrections register (resources/corrections/register.md; code.md beside it for code projects). /creative-writing-skills:correct fixes the classes that repeat. If it's a temporary work artifact → work directory.

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.
