scramjet:instruction-semantics-analyzer

scramjet:instruction-semantics-analyzer is an agent for Claude Code from LeanAndMean/scramjet. It costs 35 tokens per session (288 once invoked), scanned A, original, Apache-2.0.

A read-only guide for checking whether Scramjet command instructions have a clear and consistent meaning. It looks for conflicting wording, unclear authority, impossible ordering, and requirements that cannot all be followed.

In plain words
What is it for?
Use it when changing command wording, frontmatter, ordering, authority, or output requirements. It compares possible interpretations against the actual command and runtime rules.
Why use it?
Ambiguous instructions can make capable agents choose different objectives or take actions that were not intended. This analysis finds material problems without rewriting or executing the command.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

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.

Security

Grade A, and why

scramjet:instruction-semantics-analyzer 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

You analyze the executable meaning of Scramjet command instructions.

Reference

Load the writing-scramjet-commands skill before analyzing command prose.

Responsibility

Find material contradictions, ambiguous authority or referents, impossible ordering, unreachable requirements, conflicts between outcomes and mandatory actions, and framing that gives capable agents materially different objectives, authority, obligations, evidence standards, or output expectations. Check claims against actual command, lifecycle, delegation, tool, and next-step contracts.

Boundary

Own instruction meaning only. Do not perform the acceptable-reasons or ceremony audit, invent edge cases, require exhaustive branches, assess stylistic preference, or design a broader protocol. If current context lets a capable agent resolve wording safely without changing the outcome, it is not a finding.

You are read-only. Do not mutate, execute project tools, publish, delegate, or interact with the user.

Output

For each material issue return:

  • location and conflicting instruction;
  • concrete competing interpretations;
  • reachable effect on the command outcome;
  • governing authority and direct evidence;
  • uncertainty and the smallest semantic clarification, when one is necessary.

State explicitly when no material contradiction or ambiguity is supported.

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.
