What this is

Agent Memory Wiki is a small skill bundle for giving AI agents a durable, human-readable memory trail in an Obsidian vault.

It turns this:

“I’m about to reset the context window. Preserve what matters.”

into this:

Daily Logs/2026-06-13.md
Session Logs/2026-06-13-agent-memory-wiki-open-source.md
Janitor Reports/2026-06-14-last-24h.md

The core command is /prepforreset: a context-reset workflow that writes a curated Daily Log and Session Log, then returns a short copy/paste handoff for the next agent context.

This is not raw transcript dumping. The notes are meant to be useful to humans and future agents: decisions, rationale, alternatives, artifacts, open loops, gotchas, and source references.

The bundle

Skill	Required?	What it does
obsidian	Yes	Low-level vault operations: resolve the vault path, read/search/write notes, stay inside the vault root.
prepforreset	Yes	Manual context-reset capture: creates/updates Daily Logs and Session Logs, then returns a lean handoff.
wikijanitor	Optional	Scheduled/manual reconciliation: reviews recent sessions and existing notes, writes Janitor Reports, flags gaps.

Quick start

Option A — Hermes Agent

Clone this repo, then install the skills into your Hermes profile:

git clone https://github.com/cobibean/agent-memory-wiki.git
cd agent-memory-wiki

# Pick your Obsidian vault path.
export OBSIDIAN_VAULT_PATH="$HOME/Documents/Obsidian Vault"

# Default profile install. For a named profile, add: --profile my-profile
bash scripts/install-hermes.sh --vault "$OBSIDIAN_VAULT_PATH"

Then reload skills in your running Hermes session/gateway if needed:

/reload-skills

Now try:

/prepforreset

Option B — Any agent that supports Markdown skills

Copy these folders into whatever skill directory your agent/harness uses:

skills/note-taking/obsidian/
skills/note-taking/prepforreset/
skills/note-taking/wikijanitor/   # optional

Then configure a vault path for the agent runtime:

OBSIDIAN_VAULT_PATH="/absolute/path/to/your/Obsidian Vault"

Create the expected folders inside the vault:

Daily Logs/
Session Logs/
Janitor Reports/

Finally, add /prepforreset as a command/alias that loads and follows the prepforreset skill.

Make prepforreset a slash command

Hermes

Hermes exposes installed skills as slash commands by normalizing the skill frontmatter name.

Because the skill is named:

name: prepforreset

it becomes:

/prepforreset

after the skill command cache is refreshed. Usually one of these is enough:

/reload-skills

or restart the gateway / start a fresh session.

If the command does not appear in a platform autocomplete menu, still try typing /prepforreset manually. Some chat platforms cap visible slash-command menus even when the command is dispatchable.

Generic agents

If your agent runtime has a command registry, create an alias like:

/prepforreset -> Load the prepforreset skill, load the obsidian companion skill, write the Daily Log and Session Log into OBSIDIAN_VAULT_PATH, then return the short handoff.

If your agent has no command registry, keep the prompt below as a reusable snippet.

Copy-paste prompt for your agent

Paste this into your agent after installing the skills:

You have access to an Agent Memory Wiki skill bundle with these skills:

- `obsidian`: low-level Obsidian vault operations.
- `prepforreset`: context-reset capture into Daily Logs and Session Logs.
- `wikijanitor`: optional review/reconciliation into Janitor Reports.

Set up `/prepforreset` as a command or reusable trigger.

When I type `/prepforreset` or say “prep for reset” / “prepare for a context window”:

1. Load and follow the `prepforreset` skill.
2. Load and follow the `obsidian` companion skill before any vault operation.
3. Resolve `OBSIDIAN_VAULT_PATH` or ask me for the vault path if it is missing.
4. Ensure these folders exist inside the vault:
   - `Daily Logs/`
   - `Session Logs/`
   - `Janitor Reports/`
5. Write a curated Daily Log and Session Log. Do not dump the raw transcript.
6. Include decisions, rationale, rejected alternatives when important, artifacts, lessons/gotchas, explicit open loops, inferred open loops clearly labeled, routing candidates, and source references.
7. Never write secret values. Reference only where credentials live, such as `.env` or secret manager paths.
8. Return a short response with the note paths and a lean copy/paste handoff for the next context.

If this runtime supports slash commands, register `/prepforreset` as an alias for that workflow. If it does not, treat this prompt as the command definition.

A longer standalone prompt lives at docs/agent-copy-paste-prompt.md.

What gets written

• Daily Logs/YYYY-MM-DD.md — standalone day summary.
• Session Logs/YYYY-MM-DD-short-topic-slug.md — deeper session distillation.
• Janitor Reports/YYYY-MM-DD-last-24h.md — optional review/reconciliation note.

Design principles

• Curate, don’t dump. Durable understanding, not transcript hoarding.
• Human-readable first. Agents benefit from headings, dates, links, rationale, source references.
• The wiki is source of truth. The chat handoff is only a bridge across context windows.
• No silent mutation outside Obsidian. Routing candidates can suggest memory/skill/backlog updates, but the skill does not patch other stores unless separately asked.
• Secrets are never note content. Record credential locations, never values.
• Portable by default. The skills do not assume a private fleet, host path, or vendor runtime.

Validation

Run the local validator before publishing changes:

python3 tools/validate.py

It checks skill frontmatter, required docs, executable scripts, template presence, and obvious secret-looking patterns.
