A specification workflow for RIPDPI changes. It uses OpenSpec to describe the intended change, design, implementation tasks, and checks before work is applied.

Use it for features, user-visible changes, interface or data format changes, cross-module work, and security or network changes.

It helps prevent large or risky changes from being implemented without an agreed plan and evidence that the result works.

Per session 17 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 188 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

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	$0.00017	$0.00188
Opus 5.5	$0.00007	$0.00075
Sonnet 5.5	$0.00003	$0.00038
Haiku 4.5	$0.00002	$0.00019

Security

Grade A, and why

sdd 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 yesterday.

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.

What it actually says

Specification-driven development

Use OpenSpec for every feature, behavioral epic, user-visible change, breaking contract, protobuf/JNI/wire/storage/configuration schema, cross-module change, or security/network/protocol/service-lifecycle change.

Create or find the portfolio task first with ./taskctl.
Use $openspec-propose to produce proposal, delta specs, design, mdtask tasks, and verification.
Use $openspec-apply-change only after the planning artifacts pass strict validation.
Use $openspec-archive-change only after review and complete evidence.

Narrow single-module regression fixes, tests, docs, dependency-only work, mechanical refactors, tooling, and research may use spec_mode: not-required with an allowed reason. Features and epics cannot waive OpenSpec.

Changes

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 is a skill published in the GitHub repository po4yka/RIPDPI (85 stars, last pushed yesterday), licensed BSD-3-Clause. It adds 17 tokens to every session and 188 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 2026-11-07.
