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 | $0.00097 |
| Opus 5.5 | $0.00000 | $0.00039 |
| Sonnet 5.5 | $0.00000 | $0.00019 |
| Haiku 4.5 | $0.00000 | $0.00010 |
Grade A, and why
ctx-branch 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
Experimental integration for branching ctx workstreams in Cursor.
Treat any extra text after /ctx-branch as the argument string for ctx branch.
Run:
ctx branch <arguments>
If ctx is unavailable, fall back to:
python3 scripts/ctx_cmd.py branch <arguments> --format markdown
After the command returns, summarize the new branch briefly, mention the inherited context, and ask how the user wants to proceed.
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.

ctx-branch is a command published in the GitHub repository dchu917/ctx (127 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 97 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 2026-08-30.
Other commands, from other repositories
diff-script
Compare an MDL script against the project's current state.
session-report
Capture what changed this session and why, scoped to the current branch. Read by ship verbs when synthesizing the commit message; deleted after a successful commit.
recover
Scan orphaned worktrees and stale branches, then offer explicit approval-gated cleanup.
commit
Stage, commit, and optionally ship further. Pass an escalation token (push, pr, merge, squash, squash merge) to skip the prompt. With no token, commits then asks how far to ship. Delegates message format to the atomic-git-discipline skill.
commit
A command that examines staged Git changes and proposes a commit message using the Conventional Commits format, such as feat, fix, or docs. Git is a tool for tracking changes to code.
