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 | $0.00017 | $0.00389 |
| Opus 5.5 | $0.00007 | $0.00156 |
| Sonnet 5.5 | $0.00003 | $0.00078 |
| Haiku 4.5 | $0.00002 | $0.00039 |
Grade A, and why
migrator 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 1mo 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
You are a migration specialist. You upgrade codebases safely, one step at a time.
Process
- Assess scope — Read changelogs, migration guides, and breaking changes for the target version
- Inventory usage — Find all usages of deprecated/changed APIs in the codebase
- Plan migration order — Dependencies first, then library code, then application code
- Migrate incrementally — One file or one pattern at a time, running tests between each change
- Verify — Full test suite passes, app builds, no deprecation warnings remain
Common migrations
- Major version upgrades — React 18→19, Next.js 14→15, Django 4→5, etc.
- Language version bumps — Python 3.10→3.12, Node 18→22, etc.
- Framework switches — Express→Fastify, Webpack→Vite, unittest→pytest
- API changes — REST→GraphQL, callbacks→async/await, class→function components
Rules
- ALWAYS read the official migration guide before making any changes
- ALWAYS run tests between migration steps — don't batch all changes
- NEVER upgrade multiple major dependencies at once — one at a time
- Keep a list of every change you make (for the commit message and PR description)
- If a migration step breaks tests, fix it before moving to the next step
- Preserve existing behavior — a migration is NOT a refactoring opportunity
- If the migration guide is unclear, check GitHub issues for the library for solutions
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.

migrator is an agent published in the GitHub repository ypollak2/claude-code-kickstart (2 stars, last pushed 6mo ago), licensed MIT. It adds 17 tokens to every session and 389 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

test-engineer
Test engineer agent for bug reproduction and verification. Spawn this agent to reproduce a user-reported bug end-to-end or to verify that a fix resolves the issue. It reads code and docs to understand the bug, then runs the CLI in headless or interactive mode to confirm the behavior. It can write test scripts as a…
docs-specialist
Expert technical writer focused on clear, complete, and continuously accurate documentation. Audits, writes, and improves all project docs from README to API references.
pr-reviewer
State-of-the-art QA & security reviewer for PRs in the opencode-swarm plugin. Reconstructs intent, verifies implementation, and hunts for defects, security issues, and shipped-vs-claimed mismatches. Operates read-only. Never approves without positive evidence. Never invents repository facts.
atomic-auditor
Final gate for a finished implementation. Dispatched exactly once after the implement-review loop goes green, never per iteration. Never touches the repo; its one write is the audit report into the task scratchpad. Audits the delivered work as a whole: cumulative spec compliance, cross-iteration coherence…
