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 | $0.00066 | $0.00433 |
| Opus 5.5 | $0.00026 | $0.00173 |
| Sonnet 5.5 | $0.00013 | $0.00087 |
| Haiku 4.5 | $0.00007 | $0.00043 |
Grade A, and why
coding-level 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 2mo 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.
What it actually says
Levels
| N | Register | File |
|---|---|---|
| 0 | ELI5 | references/level-0.md |
| 1 | Junior | references/level-1.md |
| 2 | Mid-Level | references/level-2.md |
| 3 | Senior | references/level-3.md |
| 4 | Tech Lead | references/level-4.md |
| 5 | God | references/level-5.md |
Steps
- Read
$ARGUMENTSas N. If N is not an integer 0-5, reply with the table above and ask for a valid N. - Read
references/level-<N>.md, state once which level is now active, and apply that persona to every reply until/coding-levelis invoked again. - Ask once: "Save level N as the project default?" If yes, add or update the
Default coding level: Nentry inbackbone.ymlconventions.custom_rules(show the diff and wait for approval, per kit rules).
Project default
- First-time init records a default as a
backbone.ymlconventions.custom_rulesentry:Default coding level: N (<Register>). - Sessions without an explicit
/coding-levelstart from that default level. /coding-level Noverrides the default for the current session only, unless the user saves it in step 3.
Scope
- Tone and explanation depth only - keep following project coding rules.
- Reply in the user's language, not the persona file's.
What ships with it
6 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.
- 2mo ago First seen · 35 lines · 66 tokens per session scan A 02394f848e1c
coding-level is a skill published in the GitHub repository giang6283623/minimal-vibe-coding-kit (26 stars, last pushed 18d ago), licensed MIT. It adds 66 tokens to every session and 433 once invoked, about $0.0003 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.
