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 | $0.00183 | $0.03431 |
| Opus 5.5 | $0.00073 | $0.01372 |
| Sonnet 5.5 | $0.00037 | $0.00686 |
| Haiku 4.5 | $0.00018 | $0.00343 |
Grade A, and why
cache-components scanned grade A 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Next.js Cache Components
Auto-activation: This skill activates automatically in projects with
cacheComponents: truein next.config.
Project Detection
When starting work in a Next.js project, check if Cache Components are enabled:
# Check next.config.ts or next.config.js for cacheComponents
grep -r "cacheComponents" next.config.* 2>/dev/null
If cacheComponents: true is found, apply this skill's patterns proactively when:
- Writing React Server Components
- Implementing data fetching
- Creating Server Actions with mutations
- Optimizing page performance
- Reviewing existing component code
Cache Components enable Partial Prerendering (PPR) - mixing static HTML shells with dynamic streaming content for optimal performance.
Philosophy: Code Over Configuration
Cache Components represents a shift from segment configuration to compositional code:
| Before (Deprecated) | After (Cache Components) |
|---|---|
export const revalidate = 3600 |
cacheLife('hours') inside 'use cache' |
export const dynamic = 'force-static' |
Use 'use cache' and Suspense boundaries |
| All-or-nothing static/dynamic | Granular: static shell + cached + dynamic |
Key Principle: Components co-locate their caching, not just their data. Next.js provides build-time feedback to guide you toward optimal patterns.

What ships with it
3 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.

cache-components is a skill published in the GitHub repository sangrokjung/claude-forge (863 stars, last pushed 1mo ago), licensed MIT. It adds 183 tokens to every session and 3,431 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
