routecraft-core

routecraft-core is a skill for Claude Code, Codex from quinnsprouse/routecraft. It costs 26 tokens per session (1,469 once invoked), scanned A, original, MIT.

A set of instructions for building and editing bicycle routes with Routecraft. It keeps each route segment tied to an explicit command and shows the available road or path evidence.

In plain words
What is it for?
Use it to choose connected route segments, append or edit them, draw named routes, inspect network guidance, and export routes with a revision history.
Why use it?
It prevents an agent from silently adding unnamed connections or presenting missing information as proof that a road is safe. This makes route changes traceable and their uncertainties 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.

Security

Grade A, and why

routecraft-core 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 8d 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.

Routecraft core

Routecraft shows connected roads and paths with source evidence. You choose each segment and keep an exact revision history.

Route rules

Every exported segment must come from an explicit route append, route edit, or named route draw command.

Never insert an unnamed connector.

route choices returns connected options. It does not generate a route.

Do not claim that a road is safe. Report the available evidence and each unknown value.

Do not treat a missing access, surface, or traffic value as permission.

Start

routecraft guide next --json

guide next returns result.actions. Follow the first applicable action. Execute its invoke value when present.

Normal commands return result.nextActions when a next step exists. Follow that action before you call guide next again.

Run guide next again only when no next action is available or you need stage guidance.

Load an exact command contract before you need more options.

routecraft guide command route.append --json
routecraft guide topic network --json

The network guide includes a local demo. Run result.bundledDemo.invoke.cli or result.bundledDemo.invoke.mcp without changing its path.

References

  • @rN identifies an immutable route revision.
  • @sN identifies a directed network segment.
  • @jN identifies a junction.
  • @eN identifies one segment occurrence in a route.
  • @c... identifies a hand-drawn segment.
  • @v... identifies a hand-drawn virtual junction.

Short references stay stable inside the loaded network snapshot.

Build loop

Request connected decision legs.

routecraft route choices @r1 --unit leg --hops 1 --limit 24 --max-output 12kb --json

A leg stops at a branch, dead end, cycle, evidence change, or command bound. It keeps every exact segmentRefs value.

Inspect only choices that need more evidence.

routecraft segment get @s12 --view full --json
routecraft segment assess @s12 --profile gravel-50mm --json
routecraft segment enrich @s12 --elevation --json

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.
