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 | $0.00053 | $0.00360 |
| Opus 5 | $0.00026 | $0.00180 |
| Sonnet 5 | $0.00011 | $0.00072 |
| Haiku 4.5 | $0.00005 | $0.00036 |
Grade A, and why
catalyst-cache 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 5d 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.
What it actually says
How It Works
- Get Segment ID — Use MCP (
CatalystbyZoho_List_Cache_Segments) if available; otherwise retrieve it from the console or.catalystrc. - Load
references/cache-basics.md— for SDK operations, TTL limits (48 hr max), and thesegment.delete()/segment.update()gotchas. - String values only — All cache values are strings. Always
JSON.stringifybeforeputandJSON.parseafterget. - TTL behavior —
segment.update()resets TTL to the new value, not adds to existing.segment.delete()returnsnull(not an error) if the key is missing.
Triggers
Use this skill for: "Cache", "cache segment", "cache key", "cache value", "TTL", "in-memory store", segment.get, segment.put, segment.delete, "session data", "temporary data Catalyst", "cache vs Data Store", or "48-hour cache".

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

catalyst-cache is a skill published in the GitHub repository catalystbyzoho/agent-skills (57 stars, last pushed 7d ago), licensed Apache-2.0. It adds 53 tokens to every session and 360 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.
