What is esra-runtime?

A guide to the installed ESRA tools, which are Python programs for tasks such as experiments, metrics, logging, dashboards, and human review.

Use it when you need to locate, explain, or run ESRA utilities such as the evolution hook, experiment runner, metrics tools, or oversight tools.

It tells you where these tools are installed and how they fit into the Hermes environment. This avoids searching through the system or guessing how to run them.

Install

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.

Any agent

npx skills add rrpauls/hermes-esra --skill esra-runtime

Clone the repo

git clone --depth 1 https://github.com/rrpauls/hermes-esra

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00087	$0.00994
Opus 5	$0.00044	$0.00497
Sonnet 5	$0.00017	$0.00199
Haiku 4.5	$0.00009	$0.00099

Security

Grade A, and why

esra-runtime 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 8d 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.

ESRA Runtime

Role

You know where the ESRA runtime tools are installed for this Hermes profile and how to invoke them. Skills under esra/ are procedural knowledge; tools under the ESRA package root are executable Python helpers.

Canonical tools directory: ~/.hermes/esra/tools/
(or $HERMES_HOME/esra/tools / $ESRA_HOME/tools when those env vars are set)

Why tools live outside `skills/`

Hermes discovers skills via SKILL.md under ~/.hermes/skills/ (progressive disclosure).
ESRA tools are shared Python modules with cross-imports; they form one package, not 14 copies of scripts.
This skill bridges discovery: Hermes loads you to learn the path, then runs tools by absolute path.

How to run tools (always prefer installed absolute paths)

Do not require a git clone or a particular working directory after install.

python ~/.hermes/esra/tools/evolution_hook.py
python ~/.hermes/esra/tools/evolution_hook.py --force-cycle
python ~/.hermes/esra/tools/skill_validator.py --verbose --skills-dir ~/.hermes/skills/esra
python ~/.hermes/esra/tools/evolution_dashboard.py
python ~/.hermes/esra/tools/baseline_metrics.py
python ~/.hermes/esra/tools/experiment_runner.py list

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.

esra-runtime is a skill published in the GitHub repository rrpauls/hermes-esra (2 stars, last pushed 1mo ago), licensed MIT. It adds 87 tokens to every session and 994 once invoked, about $0.0004 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 2026-08-31.
