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 | $0.00041 | $0.00529 |
| Opus 5 | $0.00020 | $0.00264 |
| Sonnet 5 | $0.00008 | $0.00106 |
| Haiku 4.5 | $0.00004 | $0.00053 |
Grade A, and why
kirby-headless-api 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 12d 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.

Required inputs
- Consumers and auth requirements.
- Public vs private content boundaries.
- Response shape and caching policy.
- Preferred approach (KQL, representations, or routes).
Default delivery choices
- Use
.jsonrepresentations for page-backed responses. - Use KQL for cross-collection queries and filtered datasets.
- Use routes for non-page or composite endpoints.
Default response envelope
{
"status": "ok",
"data": {}
}
Caching rule
- Public endpoints: set
Cache-Controlwith a short max-age. - Authenticated endpoints: disable caching.
Common pitfalls
- Exposing private fields or drafts in JSON output.
- Caching authenticated responses.
Verification checklist
- Confirm auth requirements and public/private boundaries.
- Validate JSON output for required fields.
Workflow
- Clarify consumers, authentication, and which content is public vs private.
- Call
kirby:kirby_initand readkirby://config/apito confirm API settings. - Check plugin availability for KQL:
kirby:kirby_plugins_index. - If you need custom endpoints, inspect existing routes with
kirby:kirby_routes_index(install runtime if needed). - Search the KB with
kirby:kirby_search(examples: "headless api with kql", "json content representation", "figma auto populate", "headless kiosk"). - Use
kirby:kirby_onlineto fetch official API/KQL docs when KB coverage is insufficient. - Implement:
- enable API auth (
api.basicAuth) when required - create or update KQL queries for
/api/query - add
.jsonrepresentations for template-backed JSON
- enable API auth (
- Verify:
- request
/api/querywith Basic Auth - render
.jsonrepresentations withkirby:kirby_render_page(contentType: json)
- request
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.

kirby-headless-api is a skill published in the GitHub repository bnomei/kirby-mcp (59 stars, last pushed 12d ago), licensed MIT. It adds 41 tokens to every session and 529 once invoked, about $0.0002 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 2026-08-30.
