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 5.1 | $0.00069 | $0.00525 |
| Opus 5 | $0.00034 | $0.00262 |
| Sonnet 5 | $0.00014 | $0.00105 |
| Haiku 4.5 | $0.00007 | $0.00052 |
Grade A, and why
kverus-common-sync 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 6d 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
KVerus Common Sync
Use this skill to audit the installed kverus-common skill against the local Verus guide source tree. Set AGENT_DIR to the installed agent directory; skills are read from $AGENT_DIR/skills.
Required Check
Run the checker from the repository root:
. "$AGENT_DIR/kverus.env"
"$KVERUS_PYTHON" "$AGENT_DIR/skills/kverus-common-sync/scripts/check_sync.py"
If the user is working from a subdirectory, pass the repository root explicitly:
. "$AGENT_DIR/kverus.env"
"$KVERUS_PYTHON" "$AGENT_DIR/skills/kverus-common-sync/scripts/check_sync.py" --repo-root /path/to/project
What It Checks
The script verifies:
$AGENT_DIR/skills/kverus-commonexists and has reference files.- Every
Sources:path inkverus-common/references/*.mdpoints intodatabase/verified/code/tools/verus/source/docs/guide/src. - Every referenced guide source file exists.
- Every non-source Markdown cross-reference in reference prose uses
references/...instead of a bare.mdfilename. - Whether any referenced guide source is newer than the
kverus-commonreference that cites it.
Interpreting Results
Exit codes:
0: synchronized enough for the structural checks.1: one or more blocking errors.2: no blocking errors, but warnings such as newer guide files exist.
Warnings about newer guide files mean the reference may be stale. Inspect the listed guide file and update the corresponding kverus-common reference if the changed content matters.
Repair Policy
When a check fails:
- Fix structural errors first: missing files or bad source paths.
- Convert bare Markdown cross-references to skill-root paths such as
references/invariants.md. - For stale-source warnings, compare the cited guide source with the current reference and update only relevant summaries.
- Re-run the checker and
quick_validate.pyforkverus-common.
What ships with it
2 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.

kverus-common-sync is a skill published in the GitHub repository asterinas/KVerus (23 stars, last pushed 2d ago), licensed MIT. It adds 69 tokens to every session and 525 once invoked, about $0.0003 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.
