source-scout

source-scout is a skill for Claude Code from gtapps/claude-code-hermit. It costs 77 tokens per session (1,147 once invoked), scanned A, original, MIT.

A discovery tool for finding new RSS and web sources that fill gaps in a feed list. It compares current sources with priority categories and developing story arcs, then verifies or queues candidates.

In plain words
What is it for?
Use it interactively to verify and add sources, or on a schedule to queue candidates for later review.
Why use it?
It helps expand coverage where important categories have too few sources while avoiding duplicate entries.

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

source-scout 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Source Scout

Proactively discover and add new RSS/web sources to feed-sources.md. Complements source-health (removal) with discovery (addition). Can run on a schedule via scheduled_checks.

Flags

  • --scheduled: invoked by a scheduled check (non-interactive, no operator present). The security rule restricting automated WebFetch to domains already in feed-sources.md means the step-3 verification fetch cannot run — candidates are queued unverified for operator review instead of being auto-added.
  • No flag (default): interactive/on-demand (operator ran /source-scout). Full behavior — verify and auto-add — since the operator's live presence satisfies the security rule's intent.

Steps

  1. Read current state (in parallel):

    • feed-sources.md — extract active source names, URLs, categories. Count sources per category.
    • feed-categories.md — all P1/P2 categories and their priorities.
    • Glob .claude-code-hermit/compiled/story-arcs-*.md, read the most recent. Extract Watch-clause keywords from each active arc under ## Active.
  2. Identify gaps:

    • Any P1 or P2 category with fewer than 3 active sources is a gap category.
    • Active story arcs with Watch keywords that no current source covers by name/domain are arc gaps.
    • No gaps → log source-scout: no gaps found to SHELL.md Findings and stop.
  3. Discover candidates (up to 3 total across all gaps). Use WebSearch to find RSS feeds — for a category gap, search for RSS feeds / newsletters covering that category; for an arc gap, search for feeds covering the arc's Watch keywords.

    No flag (interactive): for each candidate, verify the feed URL with WebFetch (valid RSS/Atom XML). Discard any that 404 or return non-feed content.

    --scheduled: do NOT WebFetch candidate URLs — they are not yet in feed-sources.md, so an automated fetch would violate the domain-allowlist rule. Collect candidates from WebSearch results as-is (name, URL, gap addressed, why it surfaced), explicitly marked unverified. Skip to step 4.

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.
