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 | $0.00051 | $0.05704 |
| Opus 5 | $0.00026 | $0.02852 |
| Sonnet 5 | $0.00010 | $0.01141 |
| Haiku 4.5 | $0.00005 | $0.00570 |
Grade A, and why
klayout 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 539 lines — stays where its author put it; the contents beside it link to each section on GitHub.
KLayout Layout Operations
You control KLayout through MCP tools provided by klink-mcp. Tool names
preserve their dotted RPC names, such as layout.info, selection.get, and
shape.insert_box.
If you are unsure, call klink.guide first
klink.guide {} reports what is open, what intent state exists on disk,
the literal call for each user intention, and a suggested next action.
Every orchestrated tool result also carries next_action — follow it
verbatim. The workflow lives in tool results, not in your memory.
Core Rule
Use structured layout state as the source of truth:
selection.get
interaction.selection.latest / recent, when available
shape.query
layout.info
cell.list / cell.tree
layer counts
geometry validators
Never call view.screenshot unless the user explicitly asks for a screenshot
or visual artifact in the current conversation. Do not start screenshot capture
automatically, do not use it as a fallback, and do not ask for it as a routine
verification step.
Interaction Context Memory
klink-mcp may expose session-scoped interaction memory tools. This memory is
external to the KLayout plugin and persists under:
.klink/sessions/<session-id>/interaction_context.jsonl
Use these tools for explicit sent/pinned user intent. For the MVP, stored
memory is created when the user clicks the KLayout SEND toolbar action or
when an agent calls selection.send_context, not from every ordinary GUI
selection move:
| User phrase | First tool |
|---|---|
| sent GUI context: just sent, this area, here, that one | interaction.selection.latest or interaction.selection.recent |
| multiple recent items: these three, the previous few | interaction.selection.recent |
| exact current selection | selection.get |
explicit id such as sel_0006 |
interaction.selection.get |
| important reusable region | interaction.selection.label |
| the ruler(s) I sent / claim what I sent | interaction.selection.latest -> rulers[].id -> region.claim |
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.

klayout is a skill published in the GitHub repository klinkdev2026/klayout-klink (26 stars, last pushed 4d ago), licensed Apache-2.0. It adds 51 tokens to every session and 5,704 once invoked, about $0.0003 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.
