wiki-digest

wiki-digest

Generate a structured digest of the wiki's current state. Unlike wiki-query (which answers a specific question) and wiki-lint (which checks structural health), wiki-digest provides a high-level synthesis: what has been compiled, how it clusters, what is missing, and what connections are worth exploring.

Think of it as the weekly editorial meeting for your knowledge base.

When to use

• User asks "what's in the wiki?", "summarize what we know", "give me an overview"
• After a batch ingest to see what the new sources added
• Periodically to guide what to ingest next
• When starting a new session and wanting to orient quickly

Pre-flight (orientation guard)

Always read orientation files before running:

read_file {wiki_path}/SCHEMA.md
read_file {wiki_path}/index.md
read_file {wiki_path}/log.md

Steps

① Parse arguments:

• --since=Nd or --since=YYYY-MM-DD — scope to recent activity (default: all time)
• --focus=<topic> — narrow digest to a specific theme or tag
• --format=brief — 1-page summary; full — full analysis with all sections (default)
• --tier=<tier> — default active; also all, archived, frozen. When tiers are enabled in SCHEMA.md, the inventory/cluster/gap sections restrict to the chosen tier. Tier distribution is always reported regardless of filter.

② Activity summary (from log.md): Parse log.md entries in the time window. Count by action type:

## [YYYY-MM-DD] ingest | Article Title
## [YYYY-MM-DD] query | Question asked
## [YYYY-MM-DD] lint | N issues found

Build a timeline: what was added, when, in what order.

③ Inventory scan (from index.md):

• Total pages by type (entities, concepts, comparisons, queries)
• New pages since --since date (compare against created frontmatter)
• Most-linked pages (hub pages — count how many other pages link to each)
• Orphan pages (pages with no inbound links from index scan)

④ Theme clustering: Group pages by shared tags from SCHEMA.md taxonomy. For each cluster:

• Name the cluster (the dominant tag)
• List member pages
• Identify the "anchor page" (most linked-to within the cluster)
• Note if the cluster is well-developed (3+ pages) or sparse (1–2 pages)

⑤ Coverage gap analysis: For each cluster, check:

• Is there a concept page synthesizing the cluster? If not, flag as gap.
• Are there entities mentioned in multiple pages that lack their own page?
• Are there comparison pages where two closely related entities exist but haven't been compared?
• Are there questions in the log that were never filed as query pages?

⑥ Cross-cutting synthesis (full format only): Look across clusters for emergent connections:

• Entities that appear in 3+ clusters
• Concepts that contradict each other across clusters
• Timelines or progressions implied by multiple pages
• Open questions that span multiple areas

⑥b Tier distribution (if SCHEMA.md memory_tiers.enabled: true): Compute, for every wiki page, its tier from the driving-field date (default: published_at → fallback ingested_at). A page inherits the most recent tier across its cited sources — any active source pulls the page into active. Report:

• Counts: active: N | archived: M | frozen: K
• Pages that just crossed the archived threshold in the --since window ("aging out" list — these may deserve a refresh ingest)
• Pages pinned with tier_override: (manual overrides are respected) When tiers are disabled, skip this section entirely.

⑥c Stale custom dimensions (if SCHEMA.md declares any): For each dimension where refresh_on includes digest, scan pages and find ones whose dimension value is likely stale:

• Value still equals the initial import default
• Value hasn't been updated since a newer source was ingested for the same entity
• For type: enum fields: value is not the most recent valid option (e.g. version: 1.0 when the latest ingested version is 2.3)

Offer to re-prompt for each stale page. This is non-blocking — the user can say "skip all" and digest continues. The point is a gentle reminder, not interruption.

⑦ Suggested next actions: Based on gaps and clusters, suggest specific actions:

• "Ingest {X} to fill the gap in the {tag} cluster"
• "Create a comparison page for {A} vs {B} — they share 5 pages but no comparison"
• "Run wiki-lint — {N} orphan pages detected in the inventory"
• "The {topic} cluster has grown to 8 pages — consider writing a synthesis concept page"
