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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 172 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
What it costs to keep this loaded
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 | $0.00156 | $0.03237 |
| Opus 5 | $0.00078 | $0.01618 |
| Sonnet 5 | $0.00031 | $0.00647 |
| Haiku 4.5 | $0.00016 | $0.00324 |
Grade A, and why
daily-brief 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

daily-brief — Operational Skill
This project generates a single-page HTML daily digest covering tech / finance / politics / market data / community discussion. The pipeline runs locally via the OS scheduler (Windows Task Scheduler / macOS launchd / Linux cron, default 08:00 local time) and emits daily_reports/<YYYY-MM-DD>/<YYYY-MM-DD>.html + sidecar files (each date gets its own subdir). The date label uses the system local timezone by default — set REPORT_TZ (e.g. Asia/Shanghai, UTC) in .env.local to override.
Detailed architecture lives in code; this skill is a cheat sheet for operating and diagnosing, not a re-explanation of the system.
Project root assumption
All paths in this skill are relative to the project root (the directory that contains package.json, lib/, scripts/).
Before any command, ensure the working directory is the project root. Two cases:
-
Claude Code session opened inside the project — already there, no action needed
-
Session opened elsewhere — read the config file and
cd:# Cross-platform Node one-liner (prints the project root path): node -e "const fs=require('fs'),os=require('os'),path=require('path');const cfg=path.join(os.homedir(),'.daily-brief-config');if(fs.existsSync(cfg))console.log(fs.readFileSync(cfg,'utf8').trim());else process.exit(1)"Use the printed path:
cd "$(...)"on bash /Set-Location (...)in PowerShell.
The config file is written by node scripts/install.mjs --global. If it's missing the user hasn't done a global install — tell them to run it.

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.

daily-brief is a skill published in the GitHub repository leiting-eric/DailyBrief (352 stars, last pushed 7d ago), licensed MIT. It adds 156 tokens to every session and 3,237 once invoked, about $0.0008 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 2026-08-30.
