herdr is a background runtime that keeps coding-agent terminals and sessions running, even when a computer disconnects or restarts. It lets people and agents manage, inspect, and reconnect to sessions through a terminal interface or SSH while using tools such as Claude Code and Codex. The catalogue add-ons extend its panes and workflows.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Agent Snooping · line 16 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00065 | $0.00246 |
| Opus 5 | $0.00032 | $0.00123 |
| Sonnet 5 | $0.00013 | $0.00049 |
| Haiku 4.5 | $0.00006 | $0.00025 |
Grade A, and why
herdr-pre-release-audit 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 9d 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
Herdr Pre-release Audit
Use this skill only inside the herdr repository.
Read references/pre-release-audit.md and follow its workflow. Treat it as the source of truth for:
- choosing the release base ref
- inspecting first-parent history and merged PRs
- auditing
docs/next/CHANGELOG.md - auditing
docs/next/README.mdand staged website docs - checking
skills/herdr/SKILL.mdagainst shipped CLI and agent-control behavior - checking issue reference lines
- deciding when to run
just pre-release-checkor its component checks - running and assessing
just bench-render-scale - producing the final release-readiness report
Do not edit files during the audit unless the user explicitly asks to apply fixes. When applying fixes, keep changes scoped to the files named in the reference workflow.
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-pre-release-audit is a skill published in the GitHub repository herdrdev/herdr (36,303 stars, last pushed yesterday), licensed Apache-2.0. It adds 65 tokens to every session and 246 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.
