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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00311 |
| Opus 5 | $0.00026 | $0.00156 |
| Sonnet 5 | $0.00011 | $0.00062 |
| Haiku 4.5 | $0.00005 | $0.00031 |
Grade A, and why
sonar-guardrails 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 11d 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
Sonar Guardrails
Use these guardrails before and after TypeScript or JavaScript edits that are likely to trigger Sonar quality findings.
Workflow
-
Identify touched TypeScript and JavaScript files, especially tests, mocks, parsers, helpers, and branching-heavy code.
-
Apply the checklist while editing.
-
Re-scan the diff before finishing.
-
Run a focused repo check when the changes are code-bearing:
6529 run lint:changedUse
6529 run check:changedwhen the change also needs type checking.
Checklist
- Prefer
globalThisoverglobal. - Avoid empty mock classes; add a minimal member or use a plain object when possible.
- Avoid redundant type assertions in tests.
- Avoid nested ternaries; extract explicit statements or helper functions.
- Keep helper functions below cognitive complexity thresholds by extracting small predicates and mappers.
- Validate string-to-number parsing strictly when partial numeric input must be rejected.
- Prefer named intermediate values when repeated conditions make assertions or branches hard to read.
Reporting
- Mention any Sonar-sensitive patterns you fixed.
- If focused checks cannot run, report why and include the manual diff scan result.
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.

sonar-guardrails is a skill published in the GitHub repository 6529-Collections/6529seize-frontend (10 stars, last pushed today), licensed Apache-2.0. It adds 53 tokens to every session and 311 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 2026-08-31.
