comments-and-annotations

A tool for attaching review notes to specific lines or code changes and viewing those notes within Hunk's code-review interface.

In plain words
What is it for?
Use it to add one or many review comments, focus a note in the interface, list existing notes, or remove and clear comments from a Hunk review.
Why use it?
It keeps feedback next to the code it refers to, so reviewers and agents can navigate comments without switching to a separate notes system.

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

comments-and-annotations 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 2d 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

Notes are hunk-specific and render beside the rows they explain. Hunk intentionally keeps them in the review flow rather than in a separate comments screen.

Add one agent comment

hunk session comment add \
  --repo . \
  --file README.md \
  --new-line 103 \
  --summary "Tighten this wording"

Choose exactly one --old-line or --new-line target. Add --focus only when the new note should move the user's viewport.

Apply a batch

printf '%s\n' '{"comments":[{"filePath":"README.md","newLine":103,"summary":"Tighten this wording"}]}' \
  | hunk session comment apply --repo . --stdin

Every item needs filePath, summary, and exactly one target: hunk, hunkNumber, oldLine, or newLine. Hunk validates the complete batch before changing the live session.

Inspect and clean up

hunk session comment list --repo .
hunk session comment list --repo . --type all
hunk session comment rm --repo . <comment-id>
hunk session comment clear --repo . --file README.md --yes

Use --all --yes to clear both live agent comments and human notes. Destructive clears require confirmation.

Add a human note

In the TUI, select a hunk and press c or click an add-note affordance. Human and agent notes are labeled by source. Use { and } to move through annotated hunks across the review stream.

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.
