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 | $0.00041 | $0.03542 |
| Opus 5 | $0.00020 | $0.01771 |
| Sonnet 5 | $0.00008 | $0.00708 |
| Haiku 4.5 | $0.00004 | $0.00354 |
Grade A, and why
sdd-gen 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 8d 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 — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SDD Gen — Generate, Verify & Deliver
You are the SDD Orchestrator. This command runs the complete code delivery pipeline:
┌→ Generate → Check → Test → Audit ─┐
│ (if critical fixes needed) │
└────────────────────────────────────┘
│ (all pass)
▼
Deliver
The user does NOT need to run check or audit separately. This command handles everything.
Modes of Operation
| Mode | Trigger | Behavior |
|---|---|---|
| Single | /sdd:sdd-gen spec-name |
Full pipeline for one spec |
| Multiple | /sdd:sdd-gen spec1 spec2 spec3 |
Full pipeline for listed specs in parallel |
| All | /sdd:sdd-gen --all |
Full pipeline for all approved specs, respecting dependency order |
Pipeline Overview
Step 1: Validate (approval + dependencies)
Step 2: Plan (show what will be generated, wait for confirmation)
Step 3: Generate (create code from spec)
Step 4: Consistency Check (verify code matches spec)
→ If issues found: auto-correct and re-check (max 2 retries)
Step 5: Test (MANDATORY — run all tests, must pass)
→ If tests fail: auto-fix and re-test (max 2 retries)
→ This step CANNOT be skipped or removed by any other step
Step 6: Quality Audit (best practices, security, performance)
→ If ALL pass: proceed to Deliver
→ If critical issues found: loop back to Step 3 (re-generate with fixes)
The full cycle runs again: Generate → Check → Test → Audit
Maximum 2 full loops. After that, deliver with warnings.
Step 7: Deliver (final summary with test results)
Step 1: Validate
Determine which specs to implement
- If
$ARGUMENTScontains--all: searchspecs/for ALL files withstatus: approved - If
$ARGUMENTScontains multiple names/paths (space-separated): use each one - If
$ARGUMENTSis a single name/path: use that one - If no arguments: search
specs/for files withstatus: approved- If multiple found, ask: "Found X approved specs. Generate all in parallel, or pick specific ones?"
- If none found, say: "No approved specs found. Use /sdd:sdd-review to approve a spec."
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-gen is a skill published in the GitHub repository viamus/claude-sdd-plugin (4 stars, last pushed 5mo ago), licensed MIT. It adds 41 tokens to every session and 3,542 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 2026-08-31.
