feed-brief

feed-brief is a skill for Claude Code from gtapps/hermitd. It costs 105 tokens per session (3,411 once invoked), scanned A, original, MIT.

A feed-to-brief workflow that gathers configured sources, selects relevant items, writes a scheduled summary, delivers it, and archives it. A feed is a stream of published items such as news or updates.

In plain words
What is it for?
Use it to produce morning, evening, or custom-slot briefs based on the project's source list, categories, priorities, and writing rules.
Why use it?
It removes the repeated work of checking many sources, filtering items, and preparing separate morning or evening reports.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: mentions CLAUDE.md; mentions subagents.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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-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 11d 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 — 229 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Feed Brief

Run the full 7-phase brief pipeline for this project. Config lives at the project root (feed-sources.md, feed-categories.md, FEEDS.md); state and archive live under .hermit/.

Flags

  • --morning: slot morning. Forward-looking. Emphasize what's new since yesterday evening, what's worth opening today, emerging patterns. Tone: calm, sharp, selective.
  • --evening: slot evening. Backward-looking. Emphasize what changed during the day, what escalated or faded, what to carry into tomorrow. Tone: slightly more reflective.
  • --slot <name>: custom slot label (e.g. midday). Use <name> verbatim wherever <slot> appears below. Orientation defaults to the morning (forward-looking) framing unless the operator's FEEDS.md says otherwise.

Resolve <slot> from the flag before starting. All filenames below use that resolved value.

Steps

  1. Read FEEDS.md — brief philosophy, scoring rules, output format, and section guidance.
  2. Read feed-sources.md — full source list with types and URLs.
  3. Read feed-categories.md — operator's current focus areas and priority tiers (P1/P2).
  4. Read .hermit/config.json — the feed.enrichments.* and feed.reaction_feedback gates consulted in Phases 3 and 5b. A gate runs only when its value is true; treat an absent key as disabled.

Phase 1 — Web/RSS sources

Before dispatch, run bun ${CLAUDE_PLUGIN_ROOT}/scripts/source-fetch-result.ts new-run. Keep its returned UUID as the expected run_id for this invocation; never infer it from an existing file or the agent's reply. If generation fails, follow the wholesale fetch-failure path below without dispatching.

Dispatch the @hermitd-feed:source-fetcher subagent (model: haiku) to fetch all web and rss sources from feed-sources.md. Pass the full source list (URLs + names), the resolved <slot>, the absolute project root and output path, and the generated run_id to copy exactly into the output JSON.

Output-path contract: the agent writes its extracted items to tmp/feed-source-items-<slot>.json in the project root (never /tmp/). Pass <absolute-project-root>/tmp/feed-source-items-<slot>.json to the agent so its inherited working directory cannot redirect the write. Items are nested under sources[], each item: {title, summary, url, published_at, source, section, author}. No scoring — extraction only. After the agent returns, run:

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.
