What this skill helps you do

  • Session checkpoint creation
  • Decision and failed-path capture
  • Next-session handoff

How Session Memory Bank Maintainer works

You provide

The session goal, changed files, decisions, command results, blockers, and remaining intent

It inspects

Decision-changing evidence, rejected paths, unresolved risks, and the exact current revision

It decides

A continuation-ready checkpoint with one ordered next action and explicit prerequisites

You verify

Version-control state and validation output support every completion claim in the handoff

What it checks first

Session Memory Bank Maintainer maintains compact cross-session engineering memory by distilling verified decisions, failed approaches, changed files, validation evidence, open risks, and precise next actions at meaningful checkpoints. Use it when the work involves Session checkpoint creation, Decision and failed-path capture, Next-session handoff.

  1. The user goal and acceptance evidence at the checkpoint, not the volume of activity performed during the session.
  2. Decisions that constrain later work, including rejected alternatives and the evidence that made them unsuitable.
  3. Changed files and symbols linked to their current state, with unrelated work explicitly excluded from the handoff.
  4. Commands and observations that proved or falsified behavior, including failures that remain unresolved.
  5. The next executable action, its prerequisites, expected result, and condition that should trigger a different path.

Failure modes it recognizes

  • A chronological transcript hides the current state and forces the next session to reconstruct decisions from routine narration.
  • A handoff says tests pass without naming the command or revision, so later edits inherit confidence they did not earn.
  • Completed work and speculative next ideas are blended together, causing duplicate edits or premature implementation.
  • References point to temporary output or line numbers that changed while durable symbols and files were available.
  • Sensitive console output is copied into the checkpoint even though only the redacted finding is needed later.

Answers it will reject

  • Summarizing every tool call instead of preserving only decision-changing evidence and unresolved consequences.
  • Writing continue from here without one ordered next action, prerequisites, and an observable completion condition.
  • Calling a blocker resolved because a workaround exists when the underlying requirement or verification still fails.
  • Carrying forward stale assumptions after source changes without marking them for refresh or removal.

Decision rules it applies

  • Create a checkpoint at a decision, phase boundary, interruption, or context limit rather than after every small action.
  • Record observed facts, user decisions, and hypotheses in distinct language so confidence cannot be confused later.
  • Prefer current file and symbol links over pasted content and temporary terminal artifacts.
  • Retire completed next actions and invalidated assumptions when updating an existing session record.

Evidence it asks for

  • Compare the checkpoint file list with version-control status and the base diff to verify the stated change boundary.
  • Attach exact validation commands, exit results, and relevant failing test names to the revision they describe.
  • Resolve every durable link and confirm the named symbol or file still carries the recorded responsibility.
  • Review the final checkpoint for sensitive values, unsupported success claims, and more than one competing next action.

The method inside

  1. Establish what is actually true about session checkpoint creation from the supplied evidence, and mark what is missing.
  2. Identify the mechanism behind decision and failed-path capture rather than restating the symptom.
  3. Choose the smallest defensible change for next-session handoff, weighing impact, confidence, effort, and reversibility.
  4. Check every claim against the source

Deliverables

  • Session checkpoint creation assessment
  • Decision and failed-path capture decision and action plan
  • Next-session handoff verification checklist

Evidence requirements

  • Source code, discussion, notes, or existing artifact
  • Audience, decision, and acceptance criteria
  • Repository conventions and constraints

Quality gates

  • Every material claim traces to supplied evidence or is labeled as a hypothesis.
  • The response follows the declared deliverable contract.
  • No execution, access, measurement, or verification is invented.
  • Secrets and personal data are redacted rather than repeated.
  • The user receives a concrete independent verification step.
  • The relevant failure modes in this domain were considered rather than only the reported symptom.
  • No listed anti-pattern was recommended as a solution.

Example task

Input

Summarize this coding session into a memory bank entry that preserves the decisions and verification evidence but does not repeat the full conversation.

Expected output

The checkpoint records the user goal, decisions that constrain future work, changed symbols, commands and outcomes, discarded approaches with reasons, and unresolved risks. It links back to durable code instead of pasting it, and it omits transient narration that would make retrieval noisy...

Boundaries and compatibility

Ideal for

  • Session checkpoint creation: produce a decision or artifact grounded in supplied evidence.
  • Decision and failed-path capture: produce a decision or artifact grounded in supplied evidence.
  • Next-session handoff: produce a decision or artifact grounded in supplied evidence.

Out of scope

  • Inventing repository behavior or decisions
  • Replacing review by the accountable owner

Agent compatibility

  • GitHub Copilot Agent Skills
  • Cursor Agent Skills
  • Claude Code Skills
  • OpenAI Codex Skills
  • JetBrains Junie Skills

Tool policy: Advisory by default. No tools are assumed. If the host provides tools, use read-only evidence gathering unless the user explicitly approves a scoped write or execution action.
