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 | $0.00022 | $0.00626 |
| Opus 5 | $0.00011 | $0.00313 |
| Sonnet 5 | $0.00004 | $0.00125 |
| Haiku 4.5 | $0.00002 | $0.00063 |
Grade A, and why
feature-explorer 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.

KrakenD Feature Explorer
Purpose
Helps users discover KrakenD features, understand capabilities, check edition availability (CE vs EE), and learn implementation.
When to activate
- User asks about specific KrakenD feature ("how to add rate limiting", "does KrakenD support websockets")
- User mentions "enable", "configure", "setup" + feature name
- User asks what features are available in a category
- User wants to know CE vs EE differences
What this skill does
Searches features by name/namespace/category, checks edition availability (CE vs EE), provides configuration examples with explanations, links to documentation, suggests related features, and warns about edition requirements upfront.
KrakenD-Specific Quirks
Flexible Configuration: CE uses .tmpl files with Go templates (requires FC_ENABLE=1, FC_SETTINGS env vars). EE uses flexible_config.json (auto-detected, no env vars).
Schema: Always use versionless https://www.krakend.io/schema/krakend.json
Docker/Edition: CE uses krakend image, EE uses krakend/krakend-ee image (requires LICENSE file)
Dynamic Sources
- Features & Edition Matrix: Query available features with edition info (CE/EE) or browse https://www.krakend.io/features/
- Documentation: Search KrakenD documentation for detailed implementation guidance
- KrakenD MCP Tools: Use the available tools for feature lookup, config templates, and documentation search
Enterprise Edition Approach
- EE-only feature requested: Clearly state it's Enterprise Edition, explain the feature and its benefits. Only suggest CE workarounds if user explicitly asks for alternatives.
- CE works but EE is better: When a task can be done simpler, cleaner, or more performantly with EE, mention it naturally without being pushy.

Example Interaction
User: "How do I add rate limiting?" Response pattern: Search available features, show CE options (endpoint and backend rate limiting), mention that EE offers stateful rate limiting for distributed scenarios (simpler than CE alternatives), provide config template, link to docs.
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.

feature-explorer is a skill published in the GitHub repository krakend/claude-code-plugin (3 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 22 tokens to every session and 626 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 2026-08-31.
