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 | $0.00027 | $0.02065 |
| Opus 5 | $0.00014 | $0.01033 |
| Sonnet 5 | $0.00005 | $0.00413 |
| Haiku 4.5 | $0.00003 | $0.00206 |
Grade B, and why
add-mnemon scanned grade B 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 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Mnemon — Persistent Memory
Installs mnemon in the agent container image. On each container start, mnemon setup registers Claude Code hooks that surface relevant memory before the agent responds and store new insights after each turn. Memory is written to the per-agent-group .claude/ mount and survives container restarts.
Provider Compatibility
mnemon hooks only work with --target claude-code. If the agent group uses AGENT_PROVIDER=opencode, hooks registered by mnemon setup will never fire — OpenCode spawns its own process and doesn't invoke the claude CLI at all.
Check your provider:
grep AGENT_PROVIDER .env groups/*/container.json 2>/dev/null
AGENT_PROVIDER=claude(default) — fully compatible, proceed with both Phase 2 steps.AGENT_PROVIDER=opencode— use Phase 2 (OpenCode path) instead of the standard entrypoint step.
Phase 1: Pre-flight
Check if already applied
grep -q 'MNEMON_VERSION' container/Dockerfile && echo "Already applied" || echo "Not applied"
If already applied, skip to Phase 3 (Verify).
Check latest mnemon version
curl -fsSL https://api.github.com/repos/mnemon-dev/mnemon/releases/latest | grep '"tag_name"'
Note the version (e.g. v0.1.1) — use it as MNEMON_VERSION in the next step.
Phase 2: Apply Changes (Claude Code path)
1. Dockerfile — install mnemon binary
Add after the AWS CLI block, before the Bun runtime section:
# ---- mnemon — persistent agent memory ----------------------------------------
ARG MNEMON_VERSION=0.1.1
RUN ARCH=$(dpkg --print-architecture) && \
curl -fsSL "https://github.com/mnemon-dev/mnemon/releases/download/v${MNEMON_VERSION}/mnemon_${MNEMON_VERSION}_linux_${ARCH}.tar.gz" \
| tar -xz -C /usr/local/bin mnemon && \
chmod +x /usr/local/bin/mnemon
ENV MNEMON_DATA_DIR=/home/node/.claude/mnemon
MNEMON_DATA_DIR points into the per-agent-group .claude/ mount so memory persists across container restarts. No extra volume mounts 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.

add-mnemon is a skill published in the GitHub repository taslim/nanoclaw-gws-ea (11 stars, last pushed 3mo ago), licensed MIT. It adds 27 tokens to every session and 2,065 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
