branch.diff

A command that compares two branches, which are separate lines of project history, across stored data types such as documents, vectors, event streams, and graphs.

In plain words
What is it for?
Use it to review branch differences in key-value data, JSON documents, vectors, events, and graph nodes, edges, and ontology definitions.
Why use it?
It shows exactly which authored records were added, removed, or changed between the branches without reporting generated indexes.

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.

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

branch.diff 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 yesterday.

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

Compares two branches and reports the authored entities that differ, grouped by capability and space: entries added on branch_b, removed relative to branch_a, and modified on both sides. The comparison is directional from branch_a to branch_b.

Every data primitive is compared — key-value, JSON documents, vectors, event streams, and graphs. Graph changes are reported per row class: nodes, edges, and ontology appear as separate capabilities in the result. Derived rows (search and vector indexes, graph reverse maps) are omitted. A missing branch is rejected with not_found.engine.branch.

Changes

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.

branch.diff is a command published in the GitHub repository stratalab/strata-core (2 stars, last pushed 2d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 194 tokens. 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.
