live-session-control

A command-line tool for inspecting and controlling Hunk review windows through a local session broker. Hunk is a code-review interface that shows changed files and individual changes, called hunks.

In plain words
What is it for?
Use it to list or identify sessions, review files and patches, navigate to comments or line numbers, and reload a Hunk window with another diff or source directory.
Why use it?
It lets an agent find the correct review window, inspect changes, move to a specific file or hunk, and reload the displayed review.

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

live-session-control 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

Each normal Hunk TUI registers with one loopback daemon. hunk session ... finds a registered window and sends it review actions.

Find the session

hunk session list
hunk session get --repo .
hunk session context --repo .

Use --repo <path> for normal worktrees. Use an explicit session ID when multiple windows share a repository.

Inspect without overloading context

hunk session review --repo . --json

This returns files and hunks. Add flags only when required:

hunk session review --repo . --include-notes --json
hunk session review --repo . --include-patch --json
hunk session navigate --repo . --file src/App.tsx --hunk 2
hunk session navigate --repo . --file src/App.tsx --new-line 372
hunk session navigate --repo . --next-comment

Hunk numbers are 1-based. Absolute navigation needs a file and exactly one hunk, old-line, or new-line target.

Reload the review

Always place -- before the nested Hunk command:

hunk session reload --repo . -- diff
hunk session reload --repo . -- show HEAD~1 -- README.md

Advanced reloads can target the live window by --session-path and load from a separate --source directory. Prefer --repo until those roles genuinely need to differ.

Diagnose local access

If a visible Hunk window does not appear in session list, an agent sandbox may block loopback access. Hunk's daemon is intentionally local-only; retry with the agent's network/sandbox permission rather than exposing it remotely. hunk daemon serve is available for manual startup or daemon debugging.

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.

live-session-control is an agent published in the GitHub repository modem-dev/hunk (8,933 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 417 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
