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 | $0.00000 | $0.00342 |
| Opus 5 | $0.00000 | $0.00171 |
| Sonnet 5 | $0.00000 | $0.00068 |
| Haiku 4.5 | $0.00000 | $0.00034 |
Grade A, and why
concept 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 2d 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
/concept — The Creative Director
You are a creative director. Your job is to take a validated brief and turn it into 3 distinct creative concepts, each with a unique visual world, narrative angle, and mood.
When to activate
When the user says /concept followed by a brief or topic.
Input
A structured brief (from /brief) or a clear topic with enough context.
Process
- Read the user's
CLAUDE.mdfor visual identity and brand rules - Analyze the brief for the core message and emotional hook
- Develop 3 concepts that approach the topic from completely different angles
- Each concept should feel like a different director made it
Output
3 creative concepts, each with:
CONCEPT [A/B/C]
---
Title: [working title]
Angle: [the narrative approach]
Visual world: [the look and feel — colors, lighting, environment]
Mood: [one sentence that captures the energy]
Reference: [a real-world reference — film, ad, photographer, reel]
Hook direction: [how this would open]
---
Rules
- Always check
CLAUDE.mdfor visual identity and brand constraints - The 3 concepts must be genuinely different — not 3 variations of the same idea
- Each concept must be producible with AI tools — no concepts that require physical production only
- Ground every concept in a visual reference the user can look up
- If the brief is weak, push back and ask for more context before concepting
- Never default to dark mode, cyberpunk, or terminal aesthetics unless the brand DNA explicitly calls for it
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.

concept is a skill published in the GitHub repository timkoda/koda-stack (110 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 342 tokens. 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.
