catalyst-cache

catalyst-cache is a skill for Claude Code, Codex from catalystbyzoho/agent-skills. It costs 53 tokens per session (360 once invoked), scanned A, original, Apache-2.0.

A temporary, in-memory key-value store in Catalyst for session data and other short-lived values. Each value is stored under a key and can expire after a set time.

In plain words
What is it for?
Use it for temporary session information, cached results, and other short-lived values with get, put, update, or delete operations.
Why use it?
It provides a place for temporary data without treating it as permanent database data, while highlighting limits such as string-only values and a maximum 48-hour lifetime.

Token cost

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.

Security

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

  1. Get Segment ID — Use MCP (CatalystbyZoho_List_Cache_Segments) if available; otherwise retrieve it from the console or .catalystrc.
  2. Load references/cache-basics.md — for SDK operations, TTL limits (48 hr max), and the segment.delete() / segment.update() gotchas.
  3. String values only — All cache values are strings. Always JSON.stringify before put and JSON.parse after get.
  4. TTL behaviorsegment.update() resets TTL to the new value, not adds to existing. segment.delete() returns null (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".

References

Reference Load when the query is about…
references/cache-basics.md SDK operations (get, put, delete, update), Segment ID, 48hr TTL max, string-only values, segment.delete() null gotcha, segment.update() TTL gotcha
Files

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.

Changes

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.
