A command for checking whether upstream SuperDB changes may break the project and whether its language-server version is in sync. SuperDB is the database project whose documentation this command maintains.

Use it to inspect the documented SuperDB version, compare it with upstream releases, and report possible breaking changes for human review.

It surfaces changes that could make the documentation outdated or incompatible before maintainers update the shared documentation package.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.01129
Opus 5.5	$0.00000	$0.00452
Sonnet 5.5	$0.00000	$0.00226
Haiku 4.5	$0.00000	$0.00113

Security

Grade A, and why

sync scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sync SuperDB Docs

Check for upstream SuperDB breaking changes and verify LSP version sync.

This command runs autonomously. No user confirmation required.

Context

All docs, tutorials, recipes, and grok patterns are consumed from the @chrismo/superkit npm package — superkit is the single source of truth. The upstream SuperDB repo (brimdata/super) may introduce breaking changes that need to be reflected in superkit's migration guide and expert doc; this command surfaces those so they can be addressed upstream in superkit and then pulled in here via a dependency bump.

Execution Plan

Phase 1: Breaking Change Scan

This phase is informational only — it reports findings for human review, doesn't auto-update anything.

Step 1: Extract current doc version

Read the frontmatter from node_modules/@chrismo/superkit/docs/zq-to-super-upgrades.md to get the current superdb_version. (Docs come from the superkit npm package — there is no local docs/ directory.)

Step 2: Check asdf-superdb versions.txt

Fetch https://raw.githubusercontent.com/chrismo/asdf-superdb/main/scripts/versions.txt using curl
Parse versions.txt to find all comment blocks containing "breaking" (case-insensitive) that appear after the current doc version's entries
Report any found with their associated PR links

Step 3: Check LSP CHANGELOG

Fetch https://raw.githubusercontent.com/chrismo/superdb-lsp/main/CHANGELOG.md using curl
Extract entries newer than the current doc version
Surface any "Changed", "Breaking", or "Removed" sections
If CHANGELOG is unavailable or empty, note that and move on

Step 4: Investigate breaking changes with research.sh

If breaking changes were found in Steps 2-3, use ./scripts/research.sh to gather context:

# Search issues/PRs for details on a breaking change
./scripts/research.sh search "string concatenation"

# Find the relevant commits
./scripts/research.sh commits "concat operator"

# Read the full issue/PR discussion
./scripts/research.sh issue 6486

# Check if docs were updated for the change
./scripts/research.sh code "concat"

# Compare doc pages across releases
./scripts/research.sh docs super-sql/expressions/intro --ref v0.1.0
./scripts/research.sh docs super-sql/expressions/intro --ref main

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.

Subscribe to this mod's changes

sync is a command published in the GitHub repository chrismo/superdb-mcp (1 stars, last pushed 5d ago), licensed BSD-3-Clause. It costs nothing until one of its globs matches a file; then it loads 1,129 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
