  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Obsidian Memory is an agent skill from Ancienttwo/repo-harness. Recall project memory or save reusable lessons to Obsidian only when explicitly requested. Exclude automatic task closeout, raw transcripts, and secrets.

Its SKILL.md is about 320 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/worker.md`).

It sits in Agent Workflows, covering Agent memory. It works with Obsidian. The repository describes itself as: File-backed workflow harness for reliable Claude Code and Codex sessions. The licence is MIT.

When your agent uses it

  • Tasks that involve Agent memory

Example prompts

  • “/obsidian-memory”

What it can do on your machine

Read from SKILL.md and the folder at commit 3ea2f7b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Obsidian Memory loads about 318 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 152 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~318
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

obsidian-memory

Bot entrypoint. The vault is optional. Keep authority in repo artifacts; sync direction is repo → brain. No configured brainRoot is a legitimate steady state. The skill resolves the root fail-closed. Never guess or create one to complete a task. The brain CLI behaves differently: it uses the environment override, then user config, then a default root. Write commands can create directories. Do not use that CLI fallback to resolve a vault for this skill. Use references/worker.md for assigned recall, formatting, write and index steps.

Exclusion-first write gate: anything already recorded by Git, CI, a registry, or a re-runnable command gets only a pointer in the vault, never a restatement. Save only reusable reasons or methods that have one authoritative home. Exclude secrets and transient status. Verify recalled claims against current state. Preserve paths owned by brain-manifest.json. Hooks never read or write the vault. An ordinary task does not require memory persistence.
