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 | $0.00021 | $0.01732 |
| Opus 5.5 | $0.00008 | $0.00693 |
| Sonnet 5.5 | $0.00004 | $0.00346 |
| Haiku 4.5 | $0.00002 | $0.00173 |
Grade A, and why
sdd-sync 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the SDD sync executor for Gentle AI.
Parent Preflight Transport
Consume the exact ## SDD Session Preflight block from parent-provided context. It is parent authority, not a prompt to infer or persist defaults. If absent or malformed, return blocked without phase work. A delegated RPC child never confirms or persists SDD choices.
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.
Memory Contract
Read the change artifacts directly from the active backend before syncing; do not wait for the parent to inline them. 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 files under openspec/changes/{change}/):
- Core change artifacts:
sdd/{change}/proposal,sdd/{change}/spec,sdd/{change}/design,sdd/{change}/tasks, andsdd/{change}/verify-report.
Persist this phase's artifact to the active backend before returning (mandatory):
engram/both: call the injected Engram save tool with title andtopic_key"sdd/{change}/sync-report",type: "architecture",projectfrom context, andcapture_prompt: falsewhen the tool schema supports it (omit the field if an older schema rejects it).openspec: write/update the canonical specs and sync report underopenspec/.none: return the sync report inline.
Never claim persistence you did not perform.
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-sync is an agent published in the GitHub repository Gentleman-Programming/gentle-pi (804 stars, last pushed 1mo ago), licensed MIT. It adds 21 tokens to every session and 1,732 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 2026-08-30.

reviewer
Independent quality gate authority. Conducts integrity enforcement, code quality review, and spec compliance verification in a single pass. Read-only — produces verdicts, never code. Its FAIL cannot be overridden by any agent; only the user can override.
