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 | $0.00071 | $0.02620 |
| Opus 5 | $0.00036 | $0.01310 |
| Sonnet 5 | $0.00014 | $0.00524 |
| Haiku 4.5 | $0.00007 | $0.00262 |
Grade A, and why
verify-llm-artifacts 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 — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Verify LLM Artifacts Findings
Second-pass verification for .beagle/llm-artifacts-review.json. The detection pass optimizes for recall; this pass optimizes for precision so agents do not remove or “clean” code that is still required.
When to run
- After the review-llm-artifacts skill (especially full-project scans).
- Before the fix-llm-artifacts skill when findings include deletions, dead code, or High risk.
- Whenever past runs flagged artifacts that should not have been removed.
Inputs
- Required:
.beagle/llm-artifacts-review.jsonfrom a completed review. - Optional:
$ARGUMENTS—--priority-only(verifydead_codeand anyfix_actionofdeletefirst; then others),--id N(single finding id).
If the review file is missing, exit with: Run the review-llm-artifacts skill first.
Prerequisite skills
- Load the review-verification-protocol skill — general anti–false-positive discipline, including the Anti-confabulation gate (echo the artifact from a freshly read source before any verdict). The Load + ECHO gate in step 1 is this skill's concrete instance of that rule.
- Load the llm-artifacts-detection skill — category criteria for what counts as a real issue.
Instructions
Hard gates
Objective pass conditions before you claim verification is done:
- Input parse: The JSON load command in step 1 exits 0 (no traceback). Pass: valid JSON on disk at
.beagle/llm-artifacts-review.json. - Echo before adjudicate: Step 1 has printed the full finding table (one row per
findings[]entry: id, file, line, category, description) sourced from the parsed JSON in this turn. Pass: the table exists in your output and its row count equalslen(findings)— you have not begun any verdict before it. - ID lock: Step 1 has recorded the exact id set from
findings[]and stated it explicitly. Everyresultsentry maps 1:1 to a locked id — none added, none dropped. Pass: the locked id list is printed; if at any point an apparent finding has no matching locked id, you STOP (see step 1, ID lock). - Evidence before verdict: For each finding you adjudicate, you have applied references/verification-checklist.md for its
category(or documented why the category is N/A) and recorded matching strings inchecks_performed. Pass: nostatuswithout at least one checklist-backed check or an explicit N/A note innotes. - Output contract: After writing
.beagle/llm-artifacts-verification.json, the validate command in step 4 exits 0;summarycounts equal the number ofresultsentries bystatus; theresultsid set equals the locked id set from gate 3 exactly. Pass: schema-valid JSON andresultsids == locked ids == sourcefindings[]ids.
What ships with it
1 file 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.

verify-llm-artifacts is a skill published in the GitHub repository existential-birds/beagle (80 stars, last pushed 26d ago), licensed Apache-2.0. It adds 71 tokens to every session and 2,620 once invoked, about $0.0004 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.
