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 | $0.00099 | $0.01739 |
| Opus 5.5 | $0.00040 | $0.00696 |
| Sonnet 5.5 | $0.00020 | $0.00348 |
| Haiku 4.5 | $0.00010 | $0.00174 |
Grade A, and why
runic-migrate 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.

Runic — Graph Schema Migration Tool
Runic is an Alembic-style migration framework for graph databases (FalkorDB,
Memgraph, Neo4j, ArcadeDB, Apache AGE). It tracks schema versions in a version
node inside each graph and drives upgrades/downgrades via Python scripts stored
in versions/.
- FalkorDB version node label:
(:_FalkorMigrateVersion) - All other backends:
(:_RunicMigrateVersion)
For real migration file examples see examples/.
For the full op.* API and SchemaManifest see references/op-api.md.
For autogenerate, programmatic SDK, testing, and branching see references/advanced.md.
For the initial migration workflow (dev bootstrap → baseline → production) see references/initial-migration.md.
For annotated migration patterns (rename, relabel, seed, constraint guard) see references/migration-patterns.md.
Quick-start
pip install runic # or: uv add runic
runic init # scaffold runic/ directory
# edit runic/env.py to point at your graph database instance
runic revision -m "create user index"
# edit the generated versions/*.py (see examples/ for patterns)
runic upgrade head
Directory layout (after runic init)
runic/
├── env.py # executed on every CLI call; configures adapter + context
├── script.py.mako # Mako template for new revision files
└── versions/
├── .gitkeep
└── <rev_id>_<slug>.py
Default config: runic/env.py — override with --config path/to/env.py.
When you init to a non-default location, runic writes a .runic file in the
working directory containing the path to env.py. Subsequent commands use this
as a fallback when the default runic/env.py does not exist. Commit .runic.
env.py
import os
from runic.migrate import context
from runic.migrate.adapters import create_adapter
adapter = create_adapter(
"falkordb",
url=os.getenv("FALKORDB_URL", "falkor://localhost:6379"),
graph_name=os.getenv("FALKORDB_GRAPH", "my_graph"),
)
context.configure(adapter)

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.

runic-migrate is a skill published in the GitHub repository jenreh/appkit (4 stars, last pushed 2d ago), licensed MIT. It adds 99 tokens to every session and 1,739 once invoked, about $0.0004 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.

mem0-test-integration
Verify a Mem0 integration produced by /mem0-integrate. Runs in the same workspace on the same branch (loose coupling) — installs dependencies, runs the repo's native test suite, then exercises a real end-to-end smoke flow against the user's API key. Produces a scorecard. TRIGGER when: user has just run /mem0-integrate…
maintaining-python-tests
Maintains existing pytest and Django test suites without weakening correctness. Use when asked to reduce Python test runtime or CI work, investigate slow pytest families, remove stale migration tests, consolidate repeated setup, improve Python test ownership, or measure whether a test optimization worked after merge.…
scope-creep-detector
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad pull requests, changes that grew beyond a fix, dependency additions, public API renames, config or CI edits, oversized hunks, and formatting-only files. Use when the user asks whether a change grew beyond the fix, a PR is too…
mem0-integrate
Integrate Mem0 into an existing repository using a goal-driven, TDD pipeline. Detects the repo's language automatically and asks the user to pick between Mem0 Platform (managed) and Mem0 Open Source (self-hosted). Writes failing tests before any implementation. Produces a local feature branch plus .mem0-integration/…
