What is ralph-specum-switch?

A skill for switching between active software specifications, which are documents describing what should be built. It reads the project’s specification settings and summarizes the selected specification’s state.

Use it to list available specifications, select one by exact name or path, update the active-specification marker, and review its progress and prototype dependencies.

It avoids editing the wrong specification when a project has several specification folders or similarly named documents. It also makes the current phase and dependencies visible.

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	$0.00041	$0.00446
Opus 5	$0.00020	$0.00223
Sonnet 5	$0.00008	$0.00089
Haiku 4.5	$0.00004	$0.00045

Security

Grade A, and why

ralph-specum-switch 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 9d 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.

What it actually says

Ralph Specum Switch

Use this to switch the active spec.

Derive RALPH_CODEX_PLUGIN_ROOT from this loaded skill by resolving two parent directories from the SKILL.md directory. Never derive it from the project working directory.

Contract

Read .claude/ralph-specum.local.md when present
Parse specs_dirs from frontmatter to discover all spec roots
Treat the first specs_dirs entry as the default root
Default specs root is ./specs
.current-spec lives in the default specs root
Do not guess on ambiguous names

Action

Resolve the requested target by full path or exact name.
If no target was provided, list available specs grouped by root.
If the name is ambiguous across roots, stop and require a full path.
Update .current-spec:
- bare name for the default root
- full path for non-default roots
Read the target spec state and summarize phase, progress, approval state, and present files.
Report prototype dependencies without mutating them:
- Treat a missing activePrototypes field as an empty map.
- When state exists, run "$RALPH_CODEX_PLUGIN_ROOT/scripts/prototype_records.py" select-downstream --base-path "$BASE_PATH" --state "$BASE_PATH/.ralph-state.json" using the selected spec's resolved basePath.
- Show each blocker from activeBlockers with prototype ID, status, blocked artifact or transition, returnPhase, and returnTaskIndex.
- Show staleArtifacts and staleTaskIndexes from the selection result.
- Do not reconcile, remove active entries, edit records, or change blocker data. If no overlay or stale dependency exists, preserve the existing switch output.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
