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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00011 | $0.00328 |
| Opus 5 | $0.00005 | $0.00164 |
| Sonnet 5 | $0.00002 | $0.00066 |
| Haiku 4.5 | $0.00001 | $0.00033 |
Grade A, and why
CTON 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
Compress for Context (CTON)
Run the compress-for-context tool to compress files using CTON (Compact Token-Oriented Notation) format, optimized for LLM context windows.
Instructions
- Run the compression tool on the specified file(s):
C:\mcp-servers\memory-mcp\tools\compress-for-context\compress-for-context.exe $ARGUMENTS
-
The tool supports multiple formats: JSON, YAML, Markdown, CSV/TSV, Text/Log, TypeScript/JavaScript, XML/HTML.
-
Report the compression results and token savings.
Common Options
-o, --output <path>- Output file path-l, --level <level>- Compression level: light, medium, aggressive-b, --batch- Batch mode for multiple files-r, --recursive- Process directories recursively-d, --decompress- Decompress a CTON file
Usage Examples
/project:CTON package.json- Compress a single JSON file/project:CTON ./src -b -r- Batch compress all files in src//project:CTON data.cton -d- Decompress a CTON file/project:CTON large-file.md -l aggressive- Aggressive compression
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.

CTON is a command published in the GitHub repository danielsimonjr/memory-mcp (3 stars, last pushed 2d ago), licensed MIT. It adds 11 tokens to every session and 328 once invoked, about $0.0001 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 2026-08-31.
Other commands, from other repositories
minutes-ideas
Surface recent voice memos and ideas captured from any device. Use when the user asks "what ideas did I have?", "what were my recent memos?", "what did I record while walking?", or wants to recall a captured thought.
learn
Force claude-smart to extract learnings from this session now.
session-end
I'll summarize this coding session and update the memory system with our accomplishments.
memory-store
Store an insight, decision, or pattern to memory.
cc-memory
Configure persistent memory that survives across sessions using a layered approach: split rule files for always-loaded context, auto-memory for organic learning, and optional MCP-backed long-term memory for large codebases.
analyze-context
USE WHEN you want to analyze project context before starting work on a task. Calls context + recall, then synthesizes goals, decisions, gotchas, and relevant memories into a pre-task brief.
