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 | $0.00094 | $0.02664 |
| Opus 5 | $0.00047 | $0.01332 |
| Sonnet 5 | $0.00019 | $0.00533 |
| Haiku 4.5 | $0.00009 | $0.00266 |
Grade A, and why
organizing-project-folders 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 9d 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Organizing Project Folders
Overview
Folders are a real engineering decision, not an afterthought. Each folder is a choice about what to group. A good folder maps to one piece of the work breakdown or one disposition rule (what eventually happens to its contents: kept, temporary, archived, or generated). It holds things that change together. In other words, it has high cohesion (its contents share one reason to change) and low coupling (it does not depend tightly on other folders). Its name is safe on any platform, sorts cleanly, and is easy for tools to read.
This skill puts a folder-decision checklist in front of the agent, so folders get reasoned about instead of created by default. When the structure is a step-by-step agent workflow, it also applies the Model Workspace Protocol: numbered stage folders, a context file per stage, layered context, and review gates between stages. That workflow shape is a named path of its own — see docs/02-operating-system/agentic-workflow-architecture.md for when folders are enough (and when a durable runtime is not), and templates/standard/stage-contract.md for the full per-stage contract a release-bearing or delegated stage uses.
Decision contract
- Claim checked: every folder maps to one work-breakdown piece or disposition rule with one home, its contents share one reason to change, and its name passes the naming/depth/path checks.
- Artifact observed: the work breakdown, its dictionary, and the current tree -> a folder map (outline number to path with disposition), per-folder README stubs, and a naming/depth/single-source check.
- Decision affected: warn -- accept vs rework the folder layout, or where a given file belongs.
- Failure class: junk-drawer-layout (a folder mapping to no piece or rule, or one idea with two homes).
- Next action: name the real idea or stop grouping; escalate to the owner on conflict with a saved known-good convention.
When to Use
- Laying out a new repo, service, feature, or agent workspace tree.
- Deciding where a new file or module belongs.
- A folder has become a junk drawer and no longer maps to the work.
- Turning a work breakdown into real folders, or reorganizing an existing tree.
- Designing a step-by-step agent workflow as folders on disk instead of framework code.
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.

organizing-project-folders is a skill published in the GitHub repository FlyFission/nuclear-grade-context-engineering (33 stars, last pushed yesterday), licensed MIT. It adds 94 tokens to every session and 2,664 once invoked, about $0.0005 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.
