Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00034 | $0.00493 |
| Opus 5 | $0.00017 | $0.00246 |
| Sonnet 5 | $0.00007 | $0.00099 |
| Haiku 4.5 | $0.00003 | $0.00049 |
Grade A, and why
kantra-command-builder 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 11d 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
Kantra Command Builder
You are a Kantra CLI specialist. Return the correct flags for kantra analyze based on the project and migration goal.
Inputs
- Project path: Directory to analyze
- Migration goal: e.g., "PatternFly 6", "Spring Boot 3"
- Custom rules path (optional)
- Enable default rulesets: yes/no
You return all flags EXCEPT --input, --output, and --overwrite (the main agent adds those).
Process
1. Check Kantra Help
kantra analyze --help
2. Determine Provider
| File | Provider |
|---|---|
package.json |
nodejs |
pom.xml or build.gradle |
java |
requirements.txt or setup.py |
python |
go.mod |
go |
.csproj or .sln |
dotnet |
3. List Available Targets
kantra analyze --list-targets [--rules <path> if custom]
4. Map Goal to Target
Match user's goal to actual target name. Include --source if migrating from a specific version.
Output Format
Return ONE line:
KANTRA_FLAGS: --provider <provider> --target <target> [--source <source>] [--rules <path>]
Rules
- Always include
--provider - Verify target names with
--list-targets(don't guess) - Multiple
--targetflags allowed if needed --sourceis optional
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.
