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

uvs-session 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 2mo 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.

Dispatch

The first word of $ARGUMENTS is the subcommand; the rest are its arguments. The block below runs only the context-gathering for the chosen subcommand and prints a SUBCOMMAND=... marker — follow the matching section under "Instructions".

ARGS="$ARGUMENTS"; SUB=$(printf '%s' "$ARGS" | awk '{print $1}'); REST=$(printf '%s' "$ARGS" | sed 's/^[^ ]* *//'); [ "$REST" = "$SUB" ] && REST=""

  init)
    if [ -z "$REST" ] || [ "$REST" = show ]; then "$H/session-meta.sh" show
    elif [ "$REST" = clear ]; then "$H/session-meta.sh" clear
    else F=$(printf '%s' "$REST"|awk '{print $1}'); R2=$(printf '%s' "$REST"|sed 's/^[^ ]* *//')

Instructions

Read the SUBCOMMAND=... marker printed by the dispatch block above, then read and follow the matching operation file:

  • init → skills/uvs-session/operations/init.md
  • checkpoint → skills/uvs-session/operations/checkpoint.md
  • restore → skills/uvs-session/operations/restore.md
  • end → skills/uvs-session/operations/end.md
  • auto → skills/uvs-session/operations/auto.md

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.
