daily-briefing: Research & Knowledge for AI Agents | OpenAgentSkill

Overview

Automated daily tech briefing — multi-source collection → knowledge-base deduplication → AI summarization → TTS speech synthesis, generating MP3 audio briefings

Read full documentation

Source documentation, not instructions for this website. Review permissions before running any commands.

Daily AI Audio Briefing

Automatically collect, deduplicate, summarize, and synthesize a daily tech briefing as a warm-voiced MP3 every morning.

Workspace

Collection script + summarization/TTS script
Output: briefing/YYYY-MM-DD.mp3 + .txt
Knowledge base: brain/news/YYYY-MM-DD/
Schedule: cron (recommended 8:30 AM)

Workflow

Collect — Scrape GitHub trending/rising, HN top/show/new, arXiv latest AI papers, weather
Deduplicate — Compare against brain/news/ existing entries
- New project → mark is_new
- Growth >30% → mark is_update
- Otherwise → discard
Ingest — Write new entries to brain/news/YYYY-MM-DD/
Summarize — AI composes briefing script from filtered JSON
Synthesize — TTS API → MP3 file
Cleanup — Delete briefings older than 7 days

Rules

Don't use shell-level file deletion (find -delete) — may trigger security scanners; use Python Path.unlink()
Don't assume cron environment has API keys loaded — export them before running scripts
Don't use inline python3 -c or heredocs in agent/cron mode — write to .py files first
Don't trust agent-reported "MP3 generated" — verify mtime with stat after TTS step
Don't let each source exceed 8 items — keeps briefing concise

Validation

Collection script runs successfully, all sources return data
After dedup, filtered items ≥ 3
Generated briefing text contains correct date (no placeholders)
MP3 mtime matches current time (TTS actually ran)

Pitfalls

Date placeholders not replaced (Fixed: 2026-05-12)

Symptom: Briefing shows "Year X Month X" instead of actual date
Root cause: Prompt didn't inject real date, AI made it up
Fix: Inject datetime.date.today() into summarization prompt

Wrong weather source (Fixed: 2026-05-12)

Symptom: Always reports wrong city/temperature format
Root cause: Source only provided real-time temp, no high/low
Fix: Switch to structured weather API with high/low temp

Cron security scanner false positives

Symptom: Prompt blocked by exfil_curl pattern
Fix: Mark trusted cron job with skip_injection_scan: true

Cron environment missing .env

Symptom: TTS fails with "Missing credentials"
Fix: Export API keys before script execution

Model reasoning field empty content

Symptom: Reasoning model puts output in reasoning field, content is empty
Fix: Set generous max_tokens + retry with assistant message on empty content

TTS text length limit

Symptom: Long text causes unstable TTS output
Fix: Auto-truncate at safe threshold (~3000 chars)

# Daily AI Audio Briefing

> Automatically collect, deduplicate, summarize, and synthesize a daily tech briefing as a warm-voiced MP3 every morning.

## Workspace

- Collection script + summarization/TTS script
- Output: `briefing/YYYY-MM-DD.mp3` + `.txt`
- Knowledge base: `brain/news/YYYY-MM-DD/`
- Schedule: cron (recommended 8:30 AM)

## Workflow

1. **Collect** — Scrape GitHub trending/rising, HN top/show/new, arXiv latest AI papers, weather
2. **Deduplicate** — Compare against `brain/news/` existing entries
   - New project → mark `is_new`
   - Growth >30% → mark `is_update`
   - Otherwise → discard
3. **Ingest** — Write new entries to `brain/news/YYYY-MM-DD/`
4. **Summarize** — AI composes briefing script from filtered JSON
5. **Synthesize** — TTS API → MP3 file
6. **Cleanup** — Delete briefings older than 7 days

## Rules

- Don't use shell-level file deletion (`find -delete`) — may trigger security scanners; use Python `Path.unlink()`
- Don't assume cron environment has API keys loaded — export them before running scripts
- Don't use inline `python3 -c` or heredocs in agent/cron mode — write to `.py` files first
- Don't trust agent-reported "MP3 generated" — verify mtime with `stat` after TTS step
- Don't let each source exceed 8 items — keeps briefing concise

## Validation

- [ ] Collection script runs successfully, all sources return data
- [ ] After dedup, filtered items ≥ 3
- [ ] Generated briefing text contains correct date (no placeholders)
- [ ] MP3 mtime matches current time (TTS actually ran)

## Pitfalls

### Date placeholders not replaced (Fixed: 2026-05-12)
- Symptom: Briefing shows "Year X Month X" instead of actual date
- Root cause: Prompt didn't inject real date, AI made it up
- Fix: Inject `datetime.date.today()` into summarization prompt

### Wrong weather source (Fixed: 2026-05-12)
- Symptom: Always reports wrong city/temperature format
- Root cause: Source only provided real-time temp, no high/low
- Fix: Switch to structured weather API with high/low temp

### Cron security scanner false positives
- Symptom: Prompt blocked by exfil_curl pattern
- Fix: Mark trusted cron job with `skip_injection_scan: true`

### Cron environment missing .env
- Symptom: TTS fails with "Missing credentials"
- Fix: Export API keys before script execution

### Model reasoning field empty content
- Symptom: Reasoning model puts output in `reasoning` field, `content` is empty
- Fix: Set generous `max_tokens` + retry with assistant message on empty content

### TTS text length limit
- Symptom: Long text causes unstable TTS output
- Fix: Auto-truncate at safe threshold (~3000 chars)

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

Dependency or permission surface needs review
Permission surface may require sandboxing
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
