What it does
Pi Memory is an agent skill from espennilsen/pi. Manage persistent memory across sessions. Use when asked to remember, recall, forget, or review what was stored. Covers long-term facts (MEMORY.md), daily session logs, search, and memory housekeeping.
Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Agent memory. The licence is MIT.
When your agent uses it
- Asked to remember
- Review what was stored
Example prompts
- “/pi-memory”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Deduplicate — Check for repeated sections in MEMORY.md (use memory_read target=long_term)
- Archive stale info — Remove outdated decisions or completed project references
- Consolidate daily logs — Important patterns from daily logs should be promoted to MEMORY.md
- Keep sections focused — Each ## Section should have a clear purpose
What it can do on your machine
Read from SKILL.md and the folder at commit 79d019b. 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 (its code samples are json and markdown).
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
Pi Memory loads about 985 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 347 words of instructions outside code blocks.
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.

pi-memory — Persistent Memory
A file-based memory system that persists knowledge across sessions using plain Markdown.
Architecture
<base-path>/
├── MEMORY.md # Long-term curated memory (facts, preferences, decisions)
└── memory/
├── 2026-02-11.md # Daily log — append-only session notes
├── 2026-02-10.md
└── ...- MEMORY.md — The "brain". Organized into
## Sections. Survives compaction. Editable in place. - memory/YYYY-MM-DD.md — Daily append-only logs. Timestamped entries. One file per day.
The base path defaults to cwd. Override with settings.json:
{ "pi-memory": { "path": "/path/to/memory/dir" } }Tools
memory_read
Read memory contents.
| target | description |
|---|---|
long_term | Read full MEMORY.md |
daily | Read a specific date's log (default: today). Pass date: "YYYY-MM-DD" for other dates. |
list | List all available daily log files |
memory_write
Write to memory.
| target | description |
|---|---|
daily | Append a timestamped entry to today's log. Used for session notes, progress, decisions. |
long_term | Update MEMORY.md. Pass section to replace a specific ## Section, or omit to append. |
Long-term memory sections — use section parameter to target:
memory_write target=long_term section="Preferences" content="- Prefers dark theme\n- Terminal-first tools"This replaces the content under ## Preferences. If the section doesn't exist, it's created.
Daily log entries — auto-timestamped:
memory_write target=daily content="Completed the auth refactor. Using JWT with RS256."Creates ### HH:MM entry in today's file.
memory_search
Full-text search across MEMORY.md and all daily logs.
memory_search query="JWT" limit=10Returns matching lines with ±1 line of context, grouped by file.
When to Write Memory
Always write to long-term memory when:
- User explicitly says "remember this", "save this", "note that..."
- You learn a new preference, convention, or decision
- A significant architectural or design choice is made
- You discover something about the user's workflow or environment
Always write to daily log when:
- Starting or completing significant work
- Making key decisions during a task
- Encountering and resolving blockers
- At the end of a work session (summarize what was done + next steps)
Section organization for MEMORY.md
Keep MEMORY.md well-organized with clear sections:
# Long-Term Memory
## About [User]
- Key facts, role, location, interests
## Preferences
- Communication style, tool preferences, conventions
## Active Focus
- Current projects and priorities (update as they shift)
## Decisions & Conventions
- Coding conventions, workflow rules, architectural decisions
## People & Relationships
- Key contacts and collaborators
## Recurring Patterns
- Things frequently asked about or worked onMemory Hygiene
Periodically review and clean up memory:
- Deduplicate — Check for repeated sections in MEMORY.md (use
memory_read target=long_term) - Archive stale info — Remove outdated decisions or completed project references
- Consolidate daily logs — Important patterns from daily logs should be promoted to MEMORY.md
- Keep sections focused — Each
## Sectionshould have a clear purpose
System Prompt Injection
At each agent turn, the extension automatically injects into the system prompt:
- Full MEMORY.md content
- Yesterday's daily log (if exists)
- Today's daily log (if exists)
This means the agent always has recent context without needing to call memory_read.
