inbox-refresh — Multi-Source Wiki Inbox Sync Skill

Source: wiki synthesis: last30days-clawdbot-9th-channel, birdclaw-twitter-skill, yt-dlp — plus the local skill definition at ~/.claude/skills/inbox-refresh/SKILL.md and the karpathy-wiki vault’s raw/ directory conventions.

inbox-refresh is a Claude Code skill that pulls fresh reading material from a fixed set of sources, applies a quality filter, and stages each item as a markdown stub in the karpathy-wiki’s raw/ directory — ready for the next /compile pass to triage. It is the input side of the two-phase ingest pipeline; /compile is the output side. Both halves share the same triage: frontmatter field.

Key Takeaways

• Eight ingest sources, one slash command. X/Twitter bookmarks, X posts from a tracked AI-account list, YouTube videos from the wiki-inbox playlist, podcast episodes from configured YouTube channels, recently-starred GitHub repos, Anthropic ecosystem releases/commits (the anthropic-watch source), Kill-the-Newsletter or direct-RSS newsletter feeds, and top Reddit posts from a fixed Claude/AI subreddit list. Each source has its own raw-file prefix so /compile can route on filename alone.
• Default-to-skip strict bar. Reddit, X, newsletter signals are noisy by default. The skill’s quality filter is intentionally aggressive — most pulled items end up with triage: skip:<reason> in their frontmatter, never becoming articles. The 2026-05-15 inbox-refresh batch ingested 0 / refreshed 1 / skipped 10 of 11 Reddit items. This is the success state.
• Filename prefixes drive /compile routing. x-bookmark-, reddit-, gh-star-, anthropic-watch-, newsletter-, x-research-brief-, plus YouTube title-based filenames. Each prefix maps to a distinct triage default and a distinct fallback if classification fails.
• Embedded triage: field is the handoff. Every raw stub written by inbox-refresh includes triage: ingest | refresh:topic/article | skip:<reason> in its frontmatter. /compile reads the field and routes — ingest becomes a new article, refresh becomes a 1-3 sentence prefixed note appended to an existing article, skip becomes a manifest entry only. No re-classification work on the /compile side; the strict-bar decision lives at inbox time.
• No clash with last30days briefs. Items from inbox-refresh land at raw/<prefix>-<slug>.md (per-item stubs). Items from last30days land at raw/last30days/last30days-<slug>-<date>.md (cross-platform synthesis briefs in their own subfolder). Both flow through the same /compile triage but operate on different file shapes — per-item vs cross-platform synthesis. See the Channel 9 connection article for the integration shape.
• Reddit-sourced items are visibly tagged. Every Reddit-origin article gets reddit-sourced + r-<subreddit> tags, a **Source:** Reddit: line explicitly, and refresh notes prefixed [Reddit signal — r/<sub> YYYY-MM-DD]. The strict-bar trade-off is that what does survive triage carries audit metadata.

How it fits into the pipeline

inbox-refresh (skill)              /compile (skill)
    │                                  │
    ├─ pull from 8 sources             ├─ scan raw/ for new files
    ├─ apply strict-bar filter         ├─ read triage: frontmatter
    ├─ write raw/ stubs with           ├─ route on prefix + triage value
    │   triage: field                  ├─ ingest / refresh / skip
    └─ done                            └─ append to log + manifest

inbox-refresh writes; /compile reads. The triage: field is the integration contract.

Triggers for the strict-bar

The skill defaults each source to a tier:

Source	Default triage	Real-world hit rate
X bookmarks	ingest (manually selected for the inbox already)	high — most ingest
YouTube wiki-inbox playlist	ingest (curated playlist)	high
Anthropic-watch (releases/commits)	ingest if material	medium
Newsletter feeds	refresh if topic already covered, else skip	low
GitHub stars	refresh if topic already covered, else skip	low
Reddit subs	skip by default, refresh if topic already covered	very low
X tracked-account posts	refresh if signal, else skip	low

Inbox-refresh is the gate, not the vacuum. A noisy week pulls 50+ items and ingests 3.

Try It

# In a Claude Code session inside the karpathy/ project:
/inbox-refresh
 
# Then once stubs are staged:
/compile

The skill is local-only (lives in ~/.claude/skills/), not published to a marketplace. Adapt the source list in the SKILL.md body to your own inbox surfaces — the architecture is generic; the eight sources hardcoded here reflect the karpathy wiki’s specific reading diet.
