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 | $0.00056 | $0.02481 |
| Opus 5.5 | $0.00022 | $0.00992 |
| Sonnet 5.5 | $0.00011 | $0.00496 |
| Haiku 4.5 | $0.00006 | $0.00248 |
Grade A, and why
daily-brief 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.
How it starts
The opening of the file, as written. The whole thing — 277 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Daily Brief
Surface what changed since you last looked — PR reviews, ticket updates, new assignments, mentions — from all your project tools.
Preferences
Read ~/.claude/skills/daily-brief/preferences.md using the Read tool. If not found, no preferences are set.
Context
On startup, use Bash to gather: current git branch (git branch --show-current), repo name (gh repo view --json nameWithOwner -q .nameWithOwner), and GitHub username (gh api user -q .login). Skip any that fail.
Command routing
Check $ARGUMENTS:
help→ display help then stopconfig→ interactive setup then stopreset→ delete~/.claude/skills/daily-brief/preferences.md, confirm, stop- anything else (including empty) → run the brief
Flags
Parse from $ARGUMENTS:
--since <time>— override lookback window (e.g., "2h", "yesterday", "monday")--sources <list>— comma-separated list to check only specific sources (github, linear, git, notion, slack)--verbose— show full details for each item

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.
