knowledge-wiki-merge

knowledge-wiki-merge is a skill for Claude Code, Codex from CatChen/knowledge-wiki-template. It costs 51 tokens per session (2,377 once invoked), scanned A, original, MIT.

An interactive tool for finding duplicate concept files in a knowledge wiki, a collection of linked notes. It shows possible duplicate pairs one at a time so you can merge them, dismiss them, or skip them.

In plain words
What is it for?
Run it after adding new concepts or when the wiki contains overlapping notes. Review each proposed pair and decide whether to merge, dismiss, or skip it.
Why use it?
It helps reduce repeated information and makes a growing notes collection less redundant. Merging permanently changes the files and cannot be undone.

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

knowledge-wiki-merge 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 5d 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.

Knowledge Wiki Merge

Detect duplicate concept pairs and interactively merge them. Presents one pair at a time — you decide whether to merge, dismiss (never show again), or skip. Merging is destructive and irreversible, so each decision is confirmed before execution.

Steps

1. Establish the working directory

The knowledge base root is the Git repository root. Run git rev-parse --show-toplevel and store the result as KNOWLEDGE_PATH.

Use KNOWLEDGE_PATH for all subsequent steps.

2. Find and filter duplicate candidates

Structural candidates are pairs detected by shared source material — concept files that share two or more ## Sources entries. Run:

node {KNOWLEDGE_PATH}/scripts/wiki/candidates.mjs find-shared-source-concepts

This script automatically filters out previously dismissed pairs from Wiki/.state.json. Output is { "candidates": [...] } sorted by shared source count descending. Tag each as detection: "structural". Do not pipe through head or any other truncating command — every candidate must be evaluated.

LLM pre-filter (structural only): Before proceeding, review the structural candidates and eliminate any pair that is clearly about different topics despite sharing sources — pairs where the shared sources happen to cover two unrelated ideas (e.g. applescript and email-marketing appearing in the same AppleScript email tutorial). For each eliminated pair, call:

node {KNOWLEDGE_PATH}/scripts/wiki/wiki-state.mjs dismiss-pair knowledge-wiki-merge {pathA} {pathB}

where pathA and pathB are the full relative paths (e.g. Wiki/Concepts/applescript.md). Be conservative: only dismiss pairs you are confident are unrelated. A wrongly auto-dismissed pair is hidden from all future runs and requires manually editing Wiki/.state.json to recover.

Semantic candidates are pairs identified by conceptual overlap — synonyms, one being a strict subset of the other, or articles that would naturally be merged — without necessarily sharing sources. Perform this pass by running:

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.

knowledge-wiki-merge is a skill published in the GitHub repository CatChen/knowledge-wiki-template (106 stars, last pushed 2mo ago), licensed MIT. It adds 51 tokens to every session and 2,377 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
