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.
npx agentmods add instructions/leejpsd/nextjs-cache-handler/agents-mdgit clone --depth 1 https://github.com/leejpsd/nextjs-cache-handlerWhat 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 | $0.00496 | $0.00496 |
| Opus 5 | $0.00248 | $0.00248 |
| Sonnet 5 | $0.00099 | $0.00099 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade A, and why
nextjs-cache-handler AGENTS.md 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 yesterday.
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
@leejpsd/nextjs-cache-handler — notes for AI agents
Redis cache handler for self-hosted Next.js 15/16. Ships BOTH interfaces:
cacheHandler (ISR, Next 15+16) and cacheHandlers ('use cache',
Next >= 16.1.5). Not for Vercel-hosted apps.
Full agent guidance: skills/nextjs-redis-cache/SKILL.md in this package
(also installable via npx skills add leejpsd/nextjs-cache-handler).

Rules that prevent the most common mistakes
revalidateTag(tag, "max")is SOFT = stale-while-revalidate: instant stale serve + background re-render, cross-instance convergence in ~1-2s. Brief stale content is BY DESIGN — not a bug.updateTag(tag)is HARD = delete + blocking regeneration. Requires version >= 0.3.3.cacheMaxMemorySize: 0in next.config is mandatory for multi-instance correctness. Do not remove it.DEPLOYMENT_VERSIONenv must exist at RUNTIME (Docker runner stage). Missing → cross-deploy cache bleed / static chunk 404s.- Redis Cluster needs
hashTag: true; TLS viarediss://URLs. - Build-time
ECONNREFUSEDtoward Redis is expected (build-phase gate) — only investigate if the build fails. - Redis outages degrade to a bounded in-memory fallback with automatic reconnect (backoff 1s→30s). Do not wrap cache calls in extra try/catch.

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.

nextjs-cache-handler AGENTS.md is an instructions file published in the GitHub repository leejpsd/nextjs-cache-handler (6 stars, last pushed 6d ago), licensed MIT. It adds 496 tokens to every session, about $0.0025 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 2026-08-31.
