session-start

A session-opening command that gathers project context, recent work, and relevant saved knowledge at the start of a coding session. It can also search that context for a task you mention.

In plain words
What is it for?
Orienting an AI coding session and locating background information about a specific task.
Why use it?
It reduces the time spent reconstructing what a project is, what happened recently, and where to continue. It can point out when the project has no stored context yet.

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-start 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 2d 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 Start

When invoked (/session-start):

  1. Call context_auto_orient to get full project orientation in one call
  2. Display the results: project overview, recent sessions, developer preferences, recently updated entries
  3. If the context is empty, suggest running npx repomemory analyze
  4. If the user mentioned a specific task, also run context_search with relevant keywords
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.
