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 | $0.00047 | $0.00954 |
| Opus 5 | $0.00023 | $0.00477 |
| Sonnet 5 | $0.00009 | $0.00191 |
| Haiku 4.5 | $0.00005 | $0.00095 |
Grade A, and why
codexkit-daily-brief-generator 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 3d 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Daily Brief Generator
When to Use
- Starting a workday with scattered calendar items, tasks, inbox notes, or project updates.
- Preparing a manager, founder, chief of staff, or individual contributor for the day.
- Turning yesterday's unresolved items into today's operating priorities.
- Creating a daily plan without manually reading every thread first.
Procedure
Step 1 - Gather Inputs
Collect only the information needed for today's decisions:
- calendar events with time, title, attendees, and purpose if known
- tasks due today or overdue
- unread or flagged messages that require a response
- open decisions, blockers, or escalations
- personal constraints such as focus blocks, travel, or unavailable hours
Step 2 - Classify The Day
Group the day into:
- fixed commitments
- preparation required before meetings
- top three outcomes
- decisions needed from the user
- risks, blockers, or follow-ups
Step 3 - Prioritize
Rank priorities by urgency, consequence, and dependency impact. Do not rank low-value busywork above work that unlocks other people.
Step 4 - Produce The Brief
Write a scan-friendly brief with:
- schedule snapshot
- top priorities
- meeting preparation notes
- follow-up queue
- risk flags
- suggested focus block
Inputs
| Input | Required | Format |
|---|---|---|
| Calendar items | Recommended | Time, title, attendees, purpose |
| Task list | Recommended | Task, owner, due date, status |
| Inbox or chat notes | Optional | Bullets, pasted messages, summaries |
| Project context | Optional | Milestones, blockers, open decisions |
| User constraints | Optional | Working hours, focus time, travel |
Output
## Daily Brief - [Date]
### Schedule Snapshot
| Time | Event | Preparation Needed |
|------|-------|--------------------|
### Top 3 Priorities
1. [Priority] - [why it matters today]
### Follow-ups
| Item | Person | Suggested Message | Deadline |
|------|--------|-------------------|----------|
### Risks To Watch
- [Risk] - [mitigation]
### Suggested Focus Block
- [Time window] - [work to protect]
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
