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 | $0.00012 | $0.02577 |
| Opus 5 | $0.00006 | $0.01288 |
| Sonnet 5 | $0.00002 | $0.00515 |
| Haiku 4.5 | $0.00001 | $0.00258 |
Grade C, and why
setup scanned grade C with 2 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 2d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Mnemonic Setup Skill
Configure Claude to proactively use mnemonic memory without user intervention.
Trigger Phrases
- "setup mnemonic"
- "configure mnemonic"
- "install mnemonic"
- "enable mnemonic"
- "initialize mnemonic system"
Overview
This skill configures Claude's CLAUDE.md files to enable hands-off, proactive memory operations. After setup:
- Claude automatically recalls relevant memories on every prompt
- Claude automatically captures decisions, learnings, and patterns
- All memory operations happen silently without user prompting
Pre-Flight Checks
Before setup, gather context:
# Check for existing config
test -f ~/.config/mnemonic/config.json && echo "Config exists" || echo "No config found"
# Check if user-level CLAUDE.md exists
test -f ~/.claude/CLAUDE.md && echo "User CLAUDE.md exists" || echo "User CLAUDE.md missing"
# Check if project-level CLAUDE.md exists
test -f ./CLAUDE.md && echo "Project CLAUDE.md exists" || echo "Project CLAUDE.md missing"
# Detect org from git remote
git remote get-url origin 2>/dev/null | sed -E 's|.*[:/]([^/]+)/[^/]+\.git$|\1|' | sed 's|\.git$||'
# Detect project name from git root
basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || basename "$PWD"
Setup Procedure
Step 0: Configure Memory Store Path
Ask the user where to store memories (default: ~/.claude/mnemonic).
# Check for existing config
if [ -f ~/.config/mnemonic/config.json ]; then
STORE_PATH=$(python3 -c "import json; print(json.load(open('$HOME/.config/mnemonic/config.json'))['memory_store_path'])")
echo "Existing config: $STORE_PATH"
else
STORE_PATH="~/.claude/mnemonic"
fi
After the user responds (or accepts default):
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.

setup is a skill published in the GitHub repository modeled-information-format/mnemonic (22 stars, last pushed 1mo ago), licensed MIT. It adds 12 tokens to every session and 2,577 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (asks for root, reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
