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 | $0.00011 | $0.00219 |
| Opus 5 | $0.00005 | $0.00110 |
| Sonnet 5 | $0.00002 | $0.00044 |
| Haiku 4.5 | $0.00001 | $0.00022 |
Grade A, and why
hourly scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
hourly
Display today's hourly activity reports generated automatically by the daemon.
Steps
- Resolve output directory (direct python mode):
OUTPUT_DIR="${OUTPUT_DIR:-$HOME/.claude/cobrain}"
echo "$OUTPUT_DIR"
- Build today's hourly file path and check existence:
OUTPUT_DIR="${OUTPUT_DIR:-$HOME/.claude/cobrain}"
HOURLY_FILE="$OUTPUT_DIR/$(date +%Y%m%d)-hourly.md"
test -f "$HOURLY_FILE" && echo "exists" || echo "missing"
-
If the file does not exist or is empty, report:
- "No hourly reports generated yet today. Reports are created automatically at each hour boundary when the daemon is running."
- Stop here.
-
Read and display the full contents of the hourly file using the
Readtool. -
Present the content as-is — these are pre-generated summaries, no further analysis 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.

hourly is a skill published in the GitHub repository cyrus-cai/claude-cobrain (5 stars, last pushed 6mo ago), licensed MIT. It adds 11 tokens to every session and 219 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.
