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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00092 | $0.01062 |
| Opus 5 | $0.00046 | $0.00531 |
| Sonnet 5 | $0.00018 | $0.00212 |
| Haiku 4.5 | $0.00009 | $0.00106 |
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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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" = "$SUB" ] && REST=""
H="${CLAUDE_PROJECT_DIR:-.}/.claude/hooks"
case "$SUB" in
init)
if [ -z "$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.mdcheckpoint→skills/uvs-session/operations/checkpoint.mdrestore→skills/uvs-session/operations/restore.mdend→skills/uvs-session/operations/end.mdauto→skills/uvs-session/operations/auto.md
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

uvs-session is a skill published in the GitHub repository utsavanand/uv-suite (2 stars, last pushed 2mo ago), licensed MIT. It adds 92 tokens to every session and 1,062 once invoked, about $0.0005 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 2026-08-31.
