session-continuity

Rules for carrying useful context from one coding session to the next, including past problems, prevention rules, and unfinished decisions.

In plain words
What is it for?
Use it to recall context when work starts and record lessons or pending work when it ends.
Why use it?
It reduces the need to repeat project background and helps prevent mistakes that happened in earlier sessions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

session-continuity scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Session Continuity

Maintain context across coding sessions using the ThumbGate memory system.

Session start

  1. Call the recall MCP tool to retrieve:
    • Recent prevention rules relevant to the current project
    • Past failure patterns and corrective actions
    • Active context packs from previous sessions
  2. Summarize recalled context before starting work.

Session end

  1. Capture any new feedback from the session using capture_feedback.
  2. Note any unfinished work or pending decisions as context for the next session.
  3. If new failure patterns emerged, flag them for potential prevention rule promotion.

Between sessions

  • Prevention rules persist automatically via the MCP server.
  • Lessons promoted during the session are available in future recalls.
  • Context packs expire based on configured retention policies.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

session-continuity is a cursor rule published in the GitHub repository IgorGanapolsky/ThumbGate (26 stars, last pushed 2d ago), licensed MIT. It adds 19 tokens to every session and 188 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
