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.

What it costs to keep this loaded
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 | $0.00113 | $0.02475 |
| Opus 5 | $0.00056 | $0.01238 |
| Sonnet 5 | $0.00023 | $0.00495 |
| Haiku 4.5 | $0.00011 | $0.00248 |
Grade A, and why
ring:migrating-to-lib-systemplane 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 — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Systemplane Migration (lib-systemplane)
When to use
- User requests systemplane integration for a Go service
- User asks to add hot-reloadable runtime configuration
- Task mentions "systemplane", "runtime config", "hot reload", "LISTEN/NOTIFY config", "admin.Mount"
- User asks to migrate from v4 systemplane to v5
Skip when
- Service is not a Go project
- Task does not involve runtime configuration
- Service has zero hot-reloadable knobs (everything is static env-var-at-startup config)
- Task is documentation-only or non-code
You orchestrate. Agents implement. NEVER use Edit/Write/Bash on Go source files.
All code changes go through Task(subagent_type="ring:backend-go").
TDD mandatory for all implementation gates (RED → GREEN → REFACTOR).
Systemplane Architecture
Three-step lifecycle:
systemplane.NewPostgres/systemplane.NewMongoDB— construct client (pass open*sql.DBor*mongo.Client)client.Register(namespace, key, defaultValue, opts...)— declare every key BEFOREStartclient.Start(ctx)— begin listening;Get*for reads,OnChangefor reactions

Legacy paths are DELETED — do not use lib-commons/v4/... or lib-commons/v5/commons/systemplane (extracted to its own module), and do not use Supervisor, BundleFactory, ApplyBehavior.
Provisioning is migration-only. lib-systemplane publishes systemplane.SchemaSQL() + systemplane.DefaultSeedSQL() as public artifacts and consumers MUST fold them into the service's own SQL migration pipeline via the make systemplane-ddl generator pattern (Gate 3.5). Runtime DDL provisioning is FORBIDDEN — least-privilege tenant-manager roles cannot run DDL anyway, and any boot-time runSchema-style hook is a CRITICAL deviation.
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.

ring:migrating-to-lib-systemplane is a skill published in the GitHub repository LerianStudio/ring (211 stars, last pushed 18d ago), licensed Apache-2.0. It adds 113 tokens to every session and 2,475 once invoked, about $0.0006 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 2026-09-03.
