What is continuity-checker?

A story-continuity review agent that compares new content with the established canon—the facts and rules already set for the story.

Use it to check timelines, character knowledge and descriptions, geography, worldbuilding rules, and other established facts against connected project documents.

It helps find contradictions that are easy to miss, such as timeline errors, impossible travel, changed character states, or inconsistent terminology.

Per session 58 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 385 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	$0.00058	$0.00385
Opus 5.5	$0.00023	$0.00154
Sonnet 5.5	$0.00012	$0.00077
Haiku 4.5	$0.00006	$0.00038

Measured 9d ago against content hash 4824f045a46b, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

continuity-checker 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

Continuity Checker

Cross-reference the content you are given against established canon for factual contradictions, following /story-review resources/prose-critique.md with the continuity focus. Check against what you were given and what the knowledge base (kb/) records, and say where your coverage is partial.

Find the canon a draft touches through the project's link graph (/md-validation) instead of reading everything, and check its terms against the relevant vocab.md files.

Report each contradiction with its evidence and severity, as /story-review resources/prose-critique/continuity.md describes; leave fixes to your caller.

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.
