feed-diet

feed-diet is a skill for Claude Code, Codex from cacheforge-ai/cacheforge-skills. It costs 29 tokens per session (1,101 once invoked), scanned A, original, MIT.

A tool for reviewing what you read through Hacker News, a technology discussion site, or RSS feeds, which are subscriptions to updates from websites. It creates a report with categories, text charts, and recommendations.

In plain words
What is it for?
Use it to audit a Hacker News account or an OPML file, a standard list of RSS subscriptions, and create a reading report or digest.
Why use it?
It helps reveal reading patterns that are otherwise difficult to see across many feeds.

Token cost

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.

Security

Grade A, and why

feed-diet 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 4d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/classify.sh, scripts/common.sh, scripts/feed-diet.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

🍽️ Feed Diet

Audit your information diet and get a gorgeous report showing what you actually consume.

Trigger

Activate when the user mentions any of:

  • "feed diet"
  • "information diet"
  • "audit my feeds"
  • "what am I reading"
  • "analyze my HN"
  • "reading habits"
  • "content diet"
  • "feed report"

Instructions

Audit Mode (default)

  1. Determine the data source. Ask the user for one of:

    • A Hacker News username (e.g., "tosh")
    • An OPML file path containing RSS feed subscriptions
  2. Fetch the content. Run the appropriate fetch script:

    # For HN:
    bash "$SKILL_DIR/scripts/hn-fetch.sh" USERNAME 100
    
    # For OPML:
    bash "$SKILL_DIR/scripts/opml-parse.sh" /path/to/feeds.opml
    
  3. Classify items. Pipe the fetched items through the classifier:

    cat items.jsonl | bash "$SKILL_DIR/scripts/classify.sh" > classified.jsonl
    

    The classifier uses LLM (if ANTHROPIC_API_KEY or OPENAI_API_KEY is set) or falls back to keyword matching.

  4. Generate the report. Run the main entry point:

    bash "$SKILL_DIR/scripts/feed-diet.sh" audit --hn USERNAME --limit 100
    
  5. Present the report to the user. The output is Markdown — render it directly.

Digest Mode (weekly curated reading)

When the user wants a filtered reading list based on their goals:

bash "$SKILL_DIR/scripts/feed-diet.sh" digest --hn USERNAME --goal "systems programming, distributed systems" --days 7

Quick Reference

Command Description
feed-diet audit --hn USER Full diet audit for an HN user
feed-diet audit --opml FILE Full diet audit from RSS feeds
feed-diet digest --hn USER --goal "X" Weekly digest filtered by goals

Notes for the Agent

  • Be conversational. After presenting the report, offer observations like "Looks like you're heavy on news — want me to suggest some deeper technical feeds?"
  • Suggest the digest mode if the user seems interested in filtering their reading.
  • The report is the star. Don't summarize it — present it in full. It's designed to be screenshot-worthy.
  • If classification seems off, mention that setting an LLM API key improves accuracy.

What ships with it

8 files 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.

Changes

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.
