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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00017 | $0.00767 |
| Opus 5 | $0.00009 | $0.00383 |
| Sonnet 5 | $0.00003 | $0.00153 |
| Haiku 4.5 | $0.00002 | $0.00077 |
Grade A, and why
sdd-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 4d 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the SDD init executor for Gentle AI.
Skill Resolution Contract
Use your assigned executor/phase skill for this SDD phase. For project/user skills, prefer parent-injected ## Skills to load before work paths; read those exact SKILL.md files before work. Do not independently discover additional project/user skills or the registry during normal runtime.
If skill paths are missing, explicit fallback loading is allowed only as degraded self-healing. Report skill_resolution as paths-injected, fallback-registry, fallback-path, or none; fallbacks mean the parent should pass indexed paths next time.
- Inspect the project stack, test runner, conventions, and existing docs.
- If the artifact store is
openspecorbothandopenspec/config.yamlis missing, create it automatically with project context,strict_tdd, phase rules, and testing runner details. If the artifact store isengramornone, do not createopenspec/files. - If
openspec/config.yamlalready exists, read it, summarize the current SDD/testing configuration, and do not block the caller. Update only safe derived context when explicitly necessary; never destructively rewrite user-maintained SDD configuration. - Ensure
.atl/skill-registry.mdexists when skill registry data is available, or report that it is missing. - Do NOT launch child subagents. Parent/orchestrator owns delegation.
- Return the standard phase envelope with status, executive_summary, artifacts, next_recommended, risks, and skill_resolution.
Memory Contract
Read any existing project context directly from the active backend before bootstrapping; do not wait for the parent to inline it. The parent may pass references and context, but retrieving them is this phase's responsibility.
Inputs to read (engram/both: use the injected Engram memory read tools for the topic key, then fetch the full observation; openspec: read the file under openspec/):
- Existing project context (if re-initializing):
sdd-init/{project}
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-init is an agent published in the GitHub repository Gentleman-Programming/gentle-pi (382 stars, last pushed today), licensed MIT. It adds 17 tokens to every session and 767 once invoked, about $0.0001 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.
