oaustegard/session-memory
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.

Maintain a single structured markdown document that tracks what is happening
right now in the current work session. This is within-session continuity,
distinct from remember() (cross-session semantic memory) and stash
(coarse checkpoint).
Invoke on any of these triggers:
"show session notes", "note the session", "write it down"
"before you forget", "write that down", "for when context gets compressed"
a bugfix, a design choice, a reversal after correction) and no note has
been updated for a while
Do NOT invoke for:
remember()stashEvery session note uses exactly these sections, in this order, with these
headers. **Preserve the structure on every update. Never rename or reorder
sections.** Update the *content* within sections; leave empty sections present
with a single _(nothing yet)_ placeholder.
# 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)._
Persist as a procedure memory via the remembering skill, so notes
survive container death within the session thread.

Session boundary: when the user says "session done", "wrap up",
"end session", or the conversation is clearly winding down, retag the
active note from active to archived by superseding it with the same
body and tags=["session-memory", "archived"].
One note is active at a time. If `recall(tags_all=["session-memory",
"active"])` returns more than one, the oldest is stale — archive it before
updating the current one.
On each invocation:

scratch.

supersede(). This keeps exactly one active note per session.
Target ~12K tokens for the note document. Prefer concise phrasing, but do
not truncate substantive content to hit the target — trigger
## Key Decisions consolidation (collapse related bullets) before cutting.
If the document exceeds ~20K tokens, compress ## Worklog first (merge
consecutive ✓ entries into a single summary line, keep corrections and
decisions intact).
*Rationale: we run on 200K–1M context models, so the original 2K budget
from the issue spec was over-constrained. 12K matches Claude Code's
upstream design and leaves ample room for the surrounding conversation.*
When the user asks to "show session notes", print the current note body
verbatim in a fenced code block. Do not paraphrase.
When updating silently (you triggered it yourself), confirm with a single
line: Updated session notes (note id: <short-id>). Do not dump the full
body unsolicited.
