Session Memory

What it does

When your agent uses it

• The user says session notes
• Start session notes
• Show session notes
• You recognize the current session has accumulated enough state (decisions

Example prompts

• “session notes”
• “update notes”
• “start session notes”
• “/session-memory”

Requirements

• Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Read the existing note (if any) via `recall(tags_all=["session-memory",
2. 2Update in place. Edit the relevant sections; append to ## Worklog.
3. 3Prioritize user corrections. When the user pushes back or corrects an
4. 4Deduplicate against stash and explicit memories. If an item is already
5. 5Supersede, don't append. Write the full updated document back via

What it can do on your machine

Read from SKILL.md and the folder at commit 559a6cd. 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 markdown and python).

  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

Session Memory loads about 1.6k tokens when it runs. Until then it costs about 122 tokens; SKILL.md has 603 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~122

When it runs · the whole SKILL.md, loaded when a task matches

~1.6k

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

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.

session-memory

description

Maintains a structured running-notes document during long work sessions. Use when the user says "session notes", "update notes", "start session notes", "show session notes", or when you recognize the current session has accumulated enough state (decisions, corrections, files touched, errors) that it risks being lost under context pressure. Stores notes as a procedure memory tagged [session-memory, active] so they survive container death within the same session thread.

# Session: {short title, 3-8 words, derived from the initial task}

## Current State
_What is actively being worked on right now. Explicit next step._

## Task Specification
_What the user originally asked for. Constraints, acceptance criteria,
design decisions that framed the work._

## Files and Functions
_Important paths touched or referenced, one per line, with a one-line
note on what they contain and why they matter._

## Errors & Corrections
_Errors encountered and how they were fixed. User corrections to my
approach — these have priority over routine progress entries._

## Key Decisions
_Choices made during the session with their rationale. One bullet per
decision. Lead with the choice, then the why._

## Worklog
_Terse, append-only, chronological. One line per attempt or step.
Prefix with ✓ (done), ✗ (failed), → (in progress), or ↺ (reverted)._
