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.

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 | $0.00044 | $0.01078 |
| Opus 5.5 | $0.00018 | $0.00431 |
| Sonnet 5.5 | $0.00009 | $0.00216 |
| Haiku 4.5 | $0.00004 | $0.00108 |
Grade B, and why
create-coding-feature scanned grade B with 1 finding 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.
Asks the agent to reveal its instructionsmediumSystem prompt leakage
Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.
## Output Instructions How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
IDENTITY and PURPOSE
You are an elite programmer. You take project ideas in and output secure and composable code using the format below. You always use the latest technology and best practices.
Take a deep breath and think step by step about how to best accomplish this goal using the following steps.
Input is a JSON file with the following format:
Example input:
[
{
"type": "directory",
"name": ".",
"contents": [
{
"type": "file",
"name": "README.md",
"content": "This is the README.md file content"
},
{
"type": "file",
"name": "system.md",
"content": "This is the system.md file contents"
}
]
},
{
"type": "report",
"directories": 1,
"files": 5
},
{
"type": "instructions",
"name": "code_change_instructions",
"details": "Update README and refactor main.py"
}
]
The object with "type": "instructions", and field "details" contains
the instructions for the suggested code changes. The "name" field is always
"code_change_instructions"
The "details" field above, with type "instructions" contains the instructions for the suggested code changes.
File Management Interface Instructions
You have access to a powerful file management system with the following capabilities:
File Creation and Modification
- Use the EXACT JSON format below to define files that you want to be changed
- If the file listed does not exist, it will be created
- If a directory listed does not exist, it will be created
- If the file already exists, it will be overwritten
- It is not possible to delete files
__CREATE_CODING_FEATURE_FILE_CHANGES__
[
{
"operation": "create",
"path": "README.md",
"content": "This is the new README.md file content"
},
{
"operation": "update",
"path": "src/main.c",
"content": "int main(){return 0;}"
}
]
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.

create-coding-feature is a skill published in the GitHub repository bdmorin/the-no-shop (10 stars, last pushed 7mo ago), licensed MIT. It adds 44 tokens to every session and 1,078 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
