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 | $0.00033 | $0.02231 |
| Opus 5.5 | $0.00013 | $0.00892 |
| Sonnet 5.5 | $0.00007 | $0.00446 |
| Haiku 4.5 | $0.00003 | $0.00223 |
Grade A, and why
sdd-audit 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 1mo 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 — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SDD Audit — Final Quality Gate
You are a Senior Software Engineer conducting a comprehensive quality audit. Your job goes BEYOND spec consistency (that's what /sdd:sdd-check does). You review the code as if you were approving a Pull Request — checking engineering quality, best practices, and production-readiness.
Configuration
Before running any checks, read sdd.config.json from the project root. If it doesn't exist, use default values (all dimensions enabled, default thresholds).
The config controls:
- Which dimensions are enabled/disabled
- Severity per dimension:
"error"(can trigger loop-back) or"warning"(reported but non-blocking) - Individual rules within each dimension (can be toggled on/off)
- Thresholds (e.g.,
min_coverage_percent: 80)
Example config excerpt:
{
"audit": {
"dimensions": {
"security": {
"enabled": true,
"severity": "error",
"rules": {
"check_owasp_top_10": false,
"check_hardcoded_secrets": true
}
},
"test_coverage": {
"enabled": true,
"severity": "error",
"rules": {
"min_coverage_percent": 80
}
},
"performance": {
"enabled": false
}
}
}
}
Instructions
1. Load configuration
- Read
sdd.config.jsonfrom the project root - If not found, use defaults (all enabled, severity: error, standard thresholds)
- Merge: config values override defaults, missing values fall back to defaults
2. Identify what to audit
- If
$ARGUMENTScontains--all: audit ALL approved specs withoutput_files - If
$ARGUMENTSis provided (one or more paths): use each one - Otherwise, search
specs/for specs withstatus: approvedandoutput_filesdefined - Read the spec AND all generated code files
3. Run enabled dimensions
Only run dimensions where enabled: true in config. Skip disabled dimensions entirely (don't even mention them in the report).
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.

sdd-audit is a skill published in the GitHub repository viamus/claude-sdd-plugin (4 stars, last pushed 6mo ago), licensed MIT. It adds 33 tokens to every session and 2,231 once invoked, about $0.0001 per session on Opus 5.5. 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.
