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.

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 | $0.00056 | $0.00486 |
| Opus 5.5 | $0.00022 | $0.00194 |
| Sonnet 5.5 | $0.00011 | $0.00097 |
| Haiku 4.5 | $0.00006 | $0.00049 |
Grade A, and why
plannotator-tui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
plannotator-tui: hand a document to the human for review
Only when HERDR_ENV=1 (you are running inside Herdr). Otherwise tell the human where the
file is and ask them to review it.
-
Write the document to a file. Do not paste it into chat as well.
-
Open it for review, from your own pane:
plannotator-tui herdr open docs/plans/auth.mdplannotator-tui opens beside you (or wherever the user configured it), already knowing that feedback comes back to this pane.
-
End your turn. Do not wait, poll, or read the pane. The review arrives as the next user message, as numbered feedback:
## 1. (line 12) Feedback on: "Rotate the token on every…" > Rotation on every privilege change will log people out…Address every item, then continue.
When you list files you want the human to open, you may print them as file:// hyperlinks
(OSC 8):
printf '\e]8;;file://%s\e\\%s\e]8;;\e\\\n' "$PWD/docs/plans/auth.md" "docs/plans/auth.md"
Do not promise that Ctrl-click opens them in plannotator-tui. That happens only when the human
installed the opt-in annotate-links add-on. To ask for a review, use step 2.
If plannotator-tui is not on PATH, the raw Herdr command is:
herdr plugin pane open --plugin annotate --entrypoint doc --placement split \
--direction right --target-pane "$HERDR_PANE_ID" --focus --cwd "$PWD" \
--env PLANNOTATOR_TUI_FILE="$PWD/docs/plans/auth.md" --env PLANNOTATOR_TUI_DELIVER_TO="$HERDR_PANE_ID"
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.

plannotator-tui is a skill published in the GitHub repository plannotator/herdr-annotate (672 stars, last pushed 2d ago), licensed MIT. It adds 56 tokens to every session and 486 once invoked, about $0.0002 per session on Opus 5.5. 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.
