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 | $0.00050 | $0.00605 |
| Opus 5.5 | $0.00020 | $0.00242 |
| Sonnet 5.5 | $0.00010 | $0.00121 |
| Haiku 4.5 | $0.00005 | $0.00060 |
Grade A, and why
generate-persistence 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 12d 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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a persistence end-to-end orchestrator. Generate the persistence spec and the persistence code for the aggregate diagram in $ARGUMENTS by chaining two orchestrator agents sequentially. Each agent runs the heavy fan-out in its own isolated context and returns only a one-line report — this umbrella stays lean.
This is a TWO-PHASE skill
This skill is not complete until both phases finish:
- Phase 1 —
persistence-spec:specs-generatoragent (writescommand-repo-spec.md) - Phase 2 —
persistence-spec:code-generatoragent (implements tables, mappers, repositories, integrations, and tests)
Phase 1 ends with its own confirmation line such as Persistence spec generation complete for .... That message refers to Phase 1 only. It is not the end of this skill — you MUST continue to Phase 2 immediately. The single most common failure mode of this skill is stopping after Phase 1; do not do that.
Inputs
$ARGUMENTS— the path to the aggregate's Mermaid class diagram (<dir>/<stem>.md).
Both spawned agents derive the command-side spec sibling at <dir>/<stem>.persistence/command-repo-spec.md internally per spec-core:naming-conventions. This umbrella only forwards the domain diagram path.
Workflow
Spawn each agent in its own message (via the Agent tool) and wait for it to complete before spawning the next. Do not collapse them into a single message.
Step 1 of 2 — Generate the persistence spec
Spawn the persistence-spec:specs-generator agent with prompt $ARGUMENTS.
Failure handling: if the agent reports a failure, abort the workflow and emit an ERROR: line naming the failure. Only in that case do you stop before Step 2.
Success handling: if the agent returns its normal "Persistence spec generation complete" confirmation (or any non-error completion), proceed immediately to Step 2 of 2 in your very next message. Do not summarize, do not pause, do not ask for confirmation — Phase 2 is mandatory and the user has already authorized it by invoking this umbrella.
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.

generate-persistence is a skill published in the GitHub repository voro6yov/spec-driven-development (5 stars, last pushed 12d ago), licensed Apache-2.0. It adds 50 tokens to every session and 605 once invoked, about $0.0002 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 2026-10-04.
