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 | $0.00037 | $0.02342 |
| Opus 5 | $0.00018 | $0.01171 |
| Sonnet 5 | $0.00007 | $0.00468 |
| Haiku 4.5 | $0.00004 | $0.00234 |
Grade A, and why
qa 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.
How it starts
The opening of the file, as written. The whole thing — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Slop-Guard QA Audit
Black-box QA of slop-guard through its public interfaces only. Do not read source files or tests to find bugs — discover issues by using the product as an agent or user would.
Launch parallel subagents per testing angle. File genuine issues with gh issue create. If $ARGUMENTS specifies a focus area (mcp, cli, fit, docs, workflows, or effectiveness), run only that angle. Otherwise run all 6 in parallel.
Setup
- Read
README.mdfor documented behavior. - If
mcp__slop_guard__*tools are available, fetch their schemas via tool search. - Fetch open issues to avoid duplicates:
gh issue list --repo eric-tramel/slop-guard --limit 100 --state open --json number,title,body,labels - Prefer local QA fixtures if present. Otherwise create temp files under
/tmp/slop-guard-qa. Do not write throwaway files into the repo.
Pass the open issues list into every subagent prompt.
Testing Angles
1. MCP Agent Interface (mcp)
Is the MCP surface clear, consistent, and useful for an agent?
- Tool descriptions, parameter clarity, distinction between
check_slopandcheck_slop_file - JSON output structure:
score,band,violations,counts,advice,file - Edge cases: short text, empty strings, unicode, markdown, code fences, long inputs
- Missing/unreadable file paths
- Response size and parseability
- Cross-check MCP vs CLI JSON output on the same input
Issue prefix: mcp:
2. CLI UX (cli)
Does uv run sg behave predictably?
- All flags from
sg --help:--json,--verbose,--quiet,--threshold,--score-only,--counts,--config,--version - Input modes: file paths, inline text, stdin (
-), multiple inputs - Exit codes: 0 (pass), 1 (threshold fail), 2 (error)
- Stdout/stderr separation for scripting
- Path-vs-inline-text ambiguity
- Missing files, bad config paths
Issue prefix: cli:
3. Fit Workflow (fit)
Can a user fit a custom rule config from docs alone?
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.

qa is a skill published in the GitHub repository eric-tramel/slop-guard (163 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 2,342 once invoked, about $0.0002 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.
