guardian-cache

guardian-cache is a skill for Codex from 1999AZZAR/project-guardian-mcp-server. It costs 41 tokens per session (376 once invoked), scanned A, original, MIT.

A Redis-based way to store temporary agent session data and cached results. Redis is a fast data store commonly used for short-lived information.

In plain words
What is it for?
Use it to save, retrieve, scan, and check temporary data under required mema: namespaces. It also supports positive time-to-live limits and reading values from standard input.
Why use it?
It avoids repeating expensive work and lets multiple task steps or agents share temporary state with automatic expiration.

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

guardian-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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/cache_manager.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Guardian Cache

Standardized Redis-backed caching for agents.

Prerequisites

  • Binary: Python 3.9+ must be available on the host.
  • Credentials: REDIS_URL environment variable (e.g., redis://localhost:6379/0).

Setup

  1. Install dependencies with python3 -m pip install -r skills/guardian-cache/requirements.txt.
  2. Export REDIS_URL; use .env.example only as a configuration reference.

Core Workflows

1. Store and Retrieve

  • Store: printf '%s' "$VALUE" | python3 $WORKSPACE/skills/guardian-cache/scripts/cache_manager.py set mema:cache:<name> --stdin --ttl 3600
  • Fetch: python3 $WORKSPACE/skills/guardian-cache/scripts/cache_manager.py get mema:cache:<name>

2. Search & Maintenance

  • Scan: python3 $WORKSPACE/skills/guardian-cache/scripts/cache_manager.py scan [pattern]
  • Ping: python3 $WORKSPACE/skills/guardian-cache/scripts/cache_manager.py ping

Prefer --stdin for values so secrets and private data do not appear in process listings or shell history. Explicit TTL values must be positive.

Key Naming Convention

Strictly enforce the mema: prefix:

  • mema:context:* – Session state.
  • mema:cache:* – Volatile data.
  • mema:state:* – Persistent state.
Files

What ships with it

6 files 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.
