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 | $0.00064 | $0.00636 |
| Opus 5 | $0.00032 | $0.00318 |
| Sonnet 5 | $0.00013 | $0.00127 |
| Haiku 4.5 | $0.00006 | $0.00064 |
Grade A, and why
herdr-kaji-launch 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Herdr Kaji Launch
Launch kaji in a response-identified sibling pane while preserving the caller's cwd and focus.
Input
Use the kaji command requested by the user. For kaji run, require a workflow path and Issue ID.
Unless the user explicitly supplied equivalent options, add:
--agent-runner interactive-terminal --interactive-terminal-backend herdr
Procedure
-
Check
HERDR_ENV=1and a non-emptyHERDR_PANE_ID. If either check fails, stop and tell the user to start this agent inside Herdr. Do not inspect or control the UI-focused session from outside Herdr. -
If the release-matched Herdr skill is not already in context, run
herdr --skilland read its complete output before any pane operation. Follow its guardrails if they are stricter than this skill. -
Resolve the intended cwd. Default to the caller's current working directory; use a different cwd only when the user supplied it or the target worktree was resolved explicitly.
-
Split from the explicit caller pane with
--no-focusand parse the new pane ID from the JSON response. Never predict an ID and never omit the target.herdr pane split "$HERDR_PANE_ID" \ --direction right \ --ratio 0.5 \ --cwd "$PWD" \ --no-focus -
Build one shell-quoted interactive kaji command from the user's arguments and run it in the response-derived pane ID.
herdr pane run "<response-pane-id>" \ "kaji run <workflow> <issue> --agent-runner interactive-terminal --interactive-terminal-backend herdr" -
Report the pane ID, cwd, and exact kaji argv to the user. Leave the pane open for interaction. Close it only if the user asks, and only after re-reading that exact pane ID.
Invariants
- Launch kaji as a real interactive command. Do not invoke
claude -p, Claude Code print mode, or any headless substitute for this path. - Do not use
agent startfor kaji; kaji is the command running in the pane, not the Herdr-recognized coding-agent occupant. - Do not use terminal output matching as workflow completion authority. The nested interactive
runner advances on its own
verdict.yamlartifacts. - Do not install Herdr integrations or plugins as part of launching kaji.
- Do not close, prune, or reuse any pane whose ID did not come from this split response.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

herdr-kaji-launch is a skill published in the GitHub repository apokamo/kaji (12 stars, last pushed 4d ago), licensed Apache-2.0. It adds 64 tokens to every session and 636 once invoked, about $0.0003 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.
