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 | $0.00034 | $0.01178 |
| Opus 5.5 | $0.00014 | $0.00471 |
| Sonnet 5.5 | $0.00007 | $0.00236 |
| Haiku 4.5 | $0.00003 | $0.00118 |
Grade A, and why
breadboarding 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 1mo 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Breadboarding
Breadboarding transforms a workflow description into a complete map of affordances and their relationships. The output is always a set of tables showing numbered UI and Code affordances with their Wires Out and Returns To relationships. The tables are the truth. Mermaid diagrams are optional visualizations for humans.
Use Cases
1. Mapping an Existing System
You have a workflow you're trying to understand. Provide code repo(s) and a workflow description (always from the perspective of an operator trying to make an effect happen). Output: affordance tables + optional Mermaid.
2. Designing from Shaped Parts
You have a new system sketched as an assembly of parts (mechanisms), which is what a shaping pass produces — /grill shape is one way to get there. Provide the parts list, the R (requirement/outcome), and optionally the existing system. Output: affordance tables + optional Mermaid.
3. Mixtures
An existing system that must remain as-is, plus new pieces or changes. Breadboard both together — existing affordances and new ones — showing how they connect.
Core Concepts
Places — A bounded context of interaction. The blocking test: can you interact with what's behind? No → different Place. Yes → same Place with local state changes. Places get IDs (P1, P2...) and can contain subplaces (P2.1, P2.2).
Affordances — Things you can act upon. UI affordances (U): inputs, buttons, displays. Code affordances (N): methods, subscriptions, stores, framework mechanisms.
Wiring — How affordances connect. Wires Out = control flow (what triggers what). Returns To = data flow (where output goes). Navigation wires go to Places, not to affordances inside them.
The Output: Affordance Tables
Every breadboard produces these tables:
Places Table
| # | Place | Description |
|---|---|---|
| P1 | Search Page | Main search interface |
| P2 | Detail Page | Individual result view |
UI Affordances Table
What ships with it
9 files 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.

breadboarding is a skill published in the GitHub repository koolamusic/claudefiles (121 stars, last pushed 11d ago), licensed MIT. It adds 34 tokens to every session and 1,178 once invoked, about $0.0001 per session on Opus 5.5. 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.
