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 | $0.00065 | $0.01231 |
| Opus 5 | $0.00032 | $0.00616 |
| Sonnet 5 | $0.00013 | $0.00246 |
| Haiku 4.5 | $0.00006 | $0.00123 |
Grade A, and why
brain-entry scanned grade A with 1 finding 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 6d 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.

Brain Entry
Create a capture in Open Brain from any instruction. The argument tells you what content to generate and send.
Examples
/brain-entry summarize everything we have done so far in this session and send it to my open-brain
/brain-entry log a decision: we chose Cloudflare Email Routing for email ingestion because it adds zero infrastructure
/brain-entry capture this idea: add a weekly email digest that summarizes all captures from the past 7 days
/brain-entry record that I had a productive call with Butch about the CFA merger timeline
Implementation
Step 1: Generate the content
Based on the user's instruction in the arguments:
- If the instruction says "summarize this session" or similar — review the full conversation context and produce a clear, structured summary of what was accomplished, decisions made, and outcomes.
- If the instruction describes a decision, idea, observation, task, or other capture — write it up clearly and concisely.
- If the instruction references specific context from the conversation — include the relevant details.
Write the content in first person (Troy's voice) since this is his personal knowledge base. Be substantive and specific — include names, dates, technical details, and outcomes. No filler.
Step 2: Classify the capture
Determine the best capture_type from: decision, idea, observation, task, win, blocker, question, reflection.
Determine the best brain_view from: career, personal, technical, work-internal, client.
Use your judgment based on the content. When in doubt, use observation and personal.
Step 3: POST to the captures API
Use the Bash tool with curl and a heredoc to POST to the captures API. Always use curl, not Python urllib — Cloudflare blocks Python's default user-agent with 403.
Use a heredoc for the JSON body to avoid shell escaping issues with quotes and newlines in the content. Bound the call with --max-time/--connect-timeout so a hung connection cannot block indefinitely, and capture the HTTP status alongside the body so success is verified before confirming anything to the user:
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.

brain-entry is a skill published in the GitHub repository davistroy/claude-marketplace (5 stars, last pushed 3d ago), licensed MIT. It adds 65 tokens to every session and 1,231 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
