An incremental updater for a Logseq wiki, a collection of linked Markdown notes. It compares file hashes to find source notes that changed since the last import.

Use it to synchronize new or changed source notes into the wiki. It reports changed, new, and missing sources, then merges the relevant updates.

It avoids reprocessing unchanged material and preserves existing wiki pages when incorporating new or modified information.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00063	$0.00672
Opus 5.5	$0.00025	$0.00269
Sonnet 5.5	$0.00013	$0.00134
Haiku 4.5	$0.00006	$0.00067

Measured 2mo ago against content hash a88ab1605706, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

wiki-update 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 2mo 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Logseq Update — Mise à jour incrémentale

REQUIRED: Invoke llm-wiki skill first for Logseq syntax and file format rules.

Avant de commencer

Lire wiki/_manifest.json — si absent ou last_ingest est null, dire à l'utilisateur de lancer wiki-ingest d'abord pour un ingest complet initial
Lire wiki/_master-index.md pour connaître les thèmes existants

Étape 1 : Détecter les changements

Pour chaque source (pages/.md, journals/.md, assets référencés) :

Calculer le hash actuel : shasum -a 256 <fichier> | awk '{print $1}'
Comparer au content_hash dans _manifest.json

Catégoriser :

Modifiée : hash différent de celui du manifest
Nouvelle : absente du manifest
Supprimée : dans le manifest mais fichier introuvable (signaler, ne pas supprimer la page wiki)
Inchangée : hash identique → skip

Si aucun changement détecté : informer l'utilisateur et s'arrêter.

Annoncer : "X sources modifiées, Y nouvelles, Z supprimées (signalées)"

Pour chaque source modifiée ou nouvelle, appliquer la même logique que wiki-ingest (Étapes 3 à 5), en mode merge :

Lire la page wiki existante avant d'écrire.
Intégrer les nouvelles informations sans supprimer l'existant.
Mettre à jour la propriété updated:: de la page wiki.
Recalculer les ratios provenance:: après intégration des faits.
Recalculer base_confidence:: uniquement si la liste des sources a changé (éviter le churn git).
Ne pas modifier lifecycle:: (préservé pour l'humain).
Si la page est nouvelle, initialiser lifecycle:: draft, lifecycle_changed:: [DATE], tier:: supporting.

Étape 3 : Signaler les sources supprimées

Pour chaque source supprimée :

Ne pas supprimer la page wiki correspondante
Ajouter une note dans la page wiki : > ⚠️ Source [chemin] introuvable depuis [DATE]
Logger dans _log.md

Étape 4 : Mettre à jour manifest et log

Mettre à jour _manifest.json pour les sources traitées (hash, timestamp, pages). Ajouter dans wiki/_log.md :

- [ISO8601] UPDATE — [N] sources modifiées, [M] pages mises à jour, [P] nouvelles pages

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.
