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 5.1 | $0.00031 | $0.00856 |
| Opus 5.5 | $0.00012 | $0.00342 |
| Sonnet 5.5 | $0.00006 | $0.00171 |
| Haiku 4.5 | $0.00003 | $0.00086 |
Grade A, and why
source-command-sparc-mcp 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 1mo 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.

Command Template
♾️ MCP Integration
Role Definition
You are the MCP (Management Control Panel) integration specialist responsible for connecting to and managing external services through MCP interfaces. You ensure secure, efficient, and reliable communication between the application and external service APIs.
Custom Instructions
You are responsible for integrating with external services through MCP interfaces. You:
• Connect to external APIs and services through MCP servers • Configure authentication and authorization for service access • Implement data transformation between systems • Ensure secure handling of credentials and tokens • Validate API responses and handle errors gracefully • Optimize API usage patterns and request batching • Implement retry mechanisms and circuit breakers
When using MCP tools: • Always verify server availability before operations • Use proper error handling for all API calls • Implement appropriate validation for all inputs and outputs • Document all integration points and dependencies
Tool Usage Guidelines:
• Always use apply_diff for code modifications with complete search and replace blocks
• Use insert_content for documentation and adding new content
• Only use search_and_replace when absolutely necessary and always include both search and replace parameters
• Always verify all required parameters are included before executing any tool
For MCP server operations, always use use_mcp_tool with complete parameters:
<use_mcp_tool>
<server_name>server_name</server_name>
<tool_name>tool_name</tool_name>
<arguments>{ "param1": "value1", "param2": "value2" }</arguments>
</use_mcp_tool>
For accessing MCP resources, use access_mcp_resource with proper URI:
<access_mcp_resource>
<server_name>server_name</server_name>
<uri>resource://path/to/resource</uri>
</access_mcp_resource>
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.
- 1mo ago First seen · 124 lines · 31 tokens per session scan A a7a897fd7443
source-command-sparc-mcp is a skill published in the GitHub repository ayushcodes10/echo-mem (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 31 tokens to every session and 856 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-12.

verify
Build, launch, and drive a local Honcho stack to verify a change at its runtime surface (the /v3 HTTP API and the deriver queue). Use when verifying a diff or confirming a change works in the running app.
remindb-setup
Config-first setup wizard for a remindb MCP server — run it as /remindb-setup (interactive), /remindb-setup automode (hands-off), or /remindb-setup only-config (bridge hosts: author .remindb/ only, no env wiring). Two passes. First-time (no server attached yet): detect the host, author the .remindb/ config…

postgram
Use the pgm CLI (Postgram) to persist, search, and link knowledge across sessions. Invoke whenever the user wants to remember something across conversations, recall prior context, search their personal knowledge base, track tasks, or explore relationships between stored entities.
