Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.01176 |
| Opus 5 | $0.00016 | $0.00588 |
| Sonnet 5 | $0.00006 | $0.00235 |
| Haiku 4.5 | $0.00003 | $0.00118 |
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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Knowledge Layers
Load /qi-layer when writing or editing AGENTS.md or .context/ files: it
owns the craft (four principles, contents guidelines, what doesn't belong).
Load /information-hierarchy if not already loaded for disclosure tiers.
Load /llm-writing if not already loaded.
The Five Layers
| Layer | What it holds | When to use it |
|---|---|---|
AGENTS.md |
Intent and mental model for a directory | First thing agents read on entry; what to understand before working here |
.context/ |
Contracts, architecture, rationale (CONTEXT.md); deferred work (TODO, FUTURE) |
Reference depth and tracked deferrals, co-located with the code they describe |
| KB | Cross-cutting decisions, domain concepts, patterns | Spans directories; outlives sessions; no single directory owns it |
docs/ |
User-facing documentation | Different audience, different update cadence |
| Work directory | Temporary design decisions and scratch | Not colocated with durable content; scoped to an active 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 a temporary work artifact → work directory.
When in doubt, colocate. Knowledge that depends on one subsystem belongs in that subsystem's AGENTS.md or .context/ even when it reads like a concept; the KB stays code-agnostic, holding what survives implementation change. Knowledge that lives far from what it describes rots faster: changes to the code don't trigger awareness that a distant doc needs updating.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

knowledge-layers is a skill published in the GitHub repository haowjy/creative-writing-skills (453 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 1,176 once invoked, about $0.0002 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 2026-08-30.
