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 | $0.00046 | $0.07418 |
| Opus 5 | $0.00023 | $0.03709 |
| Sonnet 5 | $0.00009 | $0.01484 |
| Haiku 4.5 | $0.00005 | $0.00742 |
Grade A, and why
init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 367 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Initialize SDD Plugin
Harness portability. This skill runs on any agent harness that loads Agent Skills — Claude Code, Codex CLI, OpenCode, Crush. Tool names used below (
AskUserQuestion,Task,TeamCreate,SendMessage,TaskCreate,ToolSearch,mcp__*,${CLAUDE_PLUGIN_ROOT}) denote capabilities, not hard requirements: map each to your harness's equivalent or use the documented fallback per${CLAUDE_PLUGIN_ROOT}/references/harness-compat.md. References toCLAUDE.mdmean the project memory file (CLAUDE.md,AGENTS.md, orCRUSH.md) per harness-compat § "Project Memory File".
Set up the project's CLAUDE.md with architecture context so Claude sessions are design-aware. This skill uses componentized convergence — each component independently checks its own state and converges. No single gate blocks other components. Running init N times produces the same result as running it once.
Starting v5.0.0, init also enforces a hardware/install precondition: the qmd CLI MUST be available on PATH (per ADR-0024). If qmd is missing, init refuses to operate so users discover the dependency at setup, not three skills deep into a workflow.
Process
Module support: If $ARGUMENTS contains --module <name>, resolve the module root using the Workspace Detection pattern from ${CLAUDE_PLUGIN_ROOT}/references/shared-patterns.md. All CLAUDE.md reads and writes in the steps below target the module's CLAUDE.md at the module root instead of the project root. If workspace detection finds no modules and --module is provided, error: "No modules detected. Run /sdd:init without --module first to set up workspace."
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.

init is a skill published in the GitHub repository joestump/claude-plugin-sdd (31 stars, last pushed 15d ago), licensed MIT. It adds 46 tokens to every session and 7,418 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.
