Kaelio/ktx is a context layer that helps AI agents query analytical databases using company knowledge, approved metrics, table metadata, and relationships between columns. Data teams use it to make warehouse queries more accurate and consistent with their organization's definitions. Its catalogue add-ons teach agents how to use ktx and its data-querying interfaces.
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 | $0.00050 | $0.01743 |
| Opus 5 | $0.00025 | $0.00872 |
| Sonnet 5 | $0.00010 | $0.00349 |
| Haiku 4.5 | $0.00005 | $0.00174 |
Grade A, and why
notion_synthesize 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 11d 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Notion Cluster Synthesis
Use this skill when a WorkUnit contains staged Notion content from pages/**, databases/**, data-sources/**, or clustered Notion evidence.
Role
Each WorkUnit is either a single Notion page/span or a topical cluster of related Notion pages, pre-grouped by embedding similarity. Read the assigned raw files, then write a small set of durable wiki entries and, when applicable, semantic-layer sources that synthesize the WorkUnit's knowledge. Write final memory directly; do not write candidates.
Required Workflow
- Read the WorkUnit notes and rawFiles list. Page content lives in
page.md;metadata.jsonholds title, path, object type, data-source ids, last edited metadata, and properties. - For each assigned page, call
read_raw_file, orread_raw_spanfor oversized pages when the notes specify a span. - Search
wiki_searchfor existing pages that overlap the WorkUnit topics. Prefer updating an existing page over creating a duplicate. - Use
context_evidence_search,context_evidence_read, andcontext_evidence_neighborsto pull supporting chunks when indexed evidence is relevant. PasschunkIdanddocumentIdvalues verbatim as returned by the evidence tools. - Write durable business knowledge with
wiki_write. Aim for a small number of high-quality pages per WorkUnit or cluster. IncluderawPathswith the exact Notion raw files that support each page. - When the Notion content defines a reusable dataset, metric, segment, join rule, source-of-truth mapping, or table with explicit columns, load
sl_capture, discover existing sources first withsl_discoverorsl_read_source, then usesl_write_sourceorsl_edit_sourceonly for a confirmed mapped non-Notion target source. IncluderawPathswith the exact Notion raw files that support the SL action. If no mapped target exists, callemit_unmapped_fallbackand keep the content wiki-only. - For every deleted raw path in the Eviction Set, call
eviction_list, decide retention, thenemit_eviction_decision. Do this even when no wiki write is needed.
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.

notion_synthesize is a skill published in the GitHub repository Kaelio/ktx (1,582 stars, last pushed 7d ago), licensed Apache-2.0. It adds 50 tokens to every session and 1,743 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.
