A skill for refreshing a short Markdown summary of recent activity in an Obsidian wiki. Obsidian is a note-taking application that stores linked Markdown pages in a local vault.

Use it to read recent log entries and changed pages, then replace wiki/hot.md with a summary of recent facts, changes, and unresolved issues.

It gives a project phase a current snapshot when the wiki summary is missing or out of date, without summarising the entire wiki.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add ihudak/ihudak-claude-plugins --skill wiki-hot

Clone the repo

git clone --depth 1 https://github.com/ihudak/ihudak-claude-plugins

Made for: Claude Code.

Or install obsidian-llm-wiki, the plugin that ships this one along with the rest of its 11 skills, 10 commands.

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	$0.00081	$0.00547
Opus 5.5	$0.00032	$0.00219
Sonnet 5.5	$0.00016	$0.00109
Haiku 4.5	$0.00008	$0.00055

Security

Grade A, and why

wiki-hot 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.

What it actually says

wiki-hot

Read skills/wiki-schema/SKILL.md fully before proceeding.

Invoke with: /wiki-hot

Step 1 — Resolve VAULT_PATH

Vault path: ~/obsidian_vault by default; set VAULT_PATH to override. WSL users with a Windows-side vault must set VAULT_PATH explicitly (e.g. /mnt/c/Users/<name>/obsidian_vault).

Step 2 — Read recent activity

Read the last 10 entries of wiki/_log.md (top of file — newest first).
Read wiki/_index.md to understand current wiki scope.
For any pages created or updated in the last 3 log entries: read those pages.

Step 3 — Write hot.md

Overwrite wiki/hot.md completely with a fresh summary following the format from wiki-schema:

---
type: meta
title: "Hot Cache"
updated: YYYY-MM-DDTHH:MM:SS
---

# Recent Context

## Last Updated
YYYY-MM-DD. [One sentence: what the most recent wiki activity was]

## Key Recent Facts
- [Most important recent knowledge in the wiki]
- [Second most important]
- [Third, only if genuinely significant]

## Recent Changes
- Created: [[list of recently created pages]]
- Updated: [[list of recently updated pages]]
- Flagged: [any unresolved contradictions or open issues, or "none"]

## Active Threads
- [Current research topic or work in progress, based on log]
- [Open question not yet resolved, or "none identified"]

Constraints:

Total file length: ≤300 words. Cut ruthlessly.
Focus on what is most likely to be useful at the start of the next session.
Do not narrate the full log history. Synthesise.

Step 4 — Append to _log.md

## [YYYY-MM-DD] hot | manual refresh

Finish

Hot cache refreshed. wiki/hot.md updated (YYYY-MM-DD).

Changes

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.
