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 | $0.00021 | $0.00301 |
| Opus 5 | $0.00010 | $0.00151 |
| Sonnet 5 | $0.00004 | $0.00060 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
semantic-theme-key-rendering 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 8d 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
SKILL: Semantic Theme-Key Rendering
Domain: terminal-ui Trigger: Use when terminal components accept semantic color names rather than hardcoded ANSI or RGB values. Source Pattern: Distilled from reviewed themed terminal text and palette resolution patterns.
Core Method
Treat incoming color props as either literal color syntax or semantic theme keys that must be resolved through the active palette. Let contextual overrides such as hover, inactive, dim, inverse, or background state win before the final style reaches the renderer. This centralizes color logic in one path so components stay portable across palettes and state transitions.
Key Rules
- Detect literal color syntax first; only unresolved values should be treated as semantic theme keys.
- Apply contextual overrides before final rendering so hover and dim states do not require duplicate component logic.
- Resolve colors through the active theme provider so palette changes propagate without rewriting call sites.
Example Application
If a status label is configured as warning and becomes dim while idle, resolve warning through the current theme, then apply the idle override before rendering the final text.
Anti-Patterns (What NOT to do)
- Do not hardcode RGB values inside every component.
- Do not ignore contextual overrides such as hover or inactive state.
- Do not duplicate theme lookup logic across unrelated terminal components.
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.

semantic-theme-key-rendering is a skill published in the GitHub repository ychampion/cskill-agents (36 stars, last pushed 5mo ago), licensed MIT. It adds 21 tokens to every session and 301 once invoked, about $0.0001 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 2026-09-03.
