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.

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 | $0.00044 | $0.00544 |
| Opus 5.5 | $0.00018 | $0.00218 |
| Sonnet 5.5 | $0.00009 | $0.00109 |
| Haiku 4.5 | $0.00004 | $0.00054 |
Grade A, and why
ecc-session-guard 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 7d 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
ECC session guard
Two small hooks from affaan-m/ECC at 4eb71d92a39cab44ad40ac9d8a6a5ccb4029d6c2 (MIT, copyright 2026 Affaan Mustafa). The scripts live in upstream-hooks/. This page is the estate wrapper. It is not a bulk install of ECC.
When to use
- An agent is editing ESLint, Prettier, Biome, Ruff, Stylelint, markdownlint, or
lint-ratchet-baseline.jsonthat already exists. - An agent is editing
.ts,.tsx,.js, or.jsxand may leaveconsole.logbehind.
Do not use this to install ECC profiles, a second orchestrator, or a memory store.
What the scripts do
upstream-hooks/config-protection.pyblocks an edit only when that config file already exists. Creating a new config is allowed. The hook fails open and writes a one-line diagnostic on stderr.upstream-hooks/check-console-log.pywarns on stderr and exits 0. Tests and scripts are excluded. It never blocks the edit.
Estate limits
- Do not point config protection at
settings.json. Frank has to be able to edit his own settings. - Do not treat a markdown handover as a lint file.
- Review state for the upstream repo is
watch. Browse named pieces. Do not copy thefullprofile into~/.hermes.
Install
Copy this folder to ~/.hermes/skills/ecc-session-guard/ and wire the two scripts only if you want them in ~/.hermes/config.yaml. Read docs/HERMES-HOOKS.md upstream before enabling a block.
License
The Python files stay under the upstream MIT notice. This SKILL.md is MIT, Frank Riemer, and names the upstream commit above.
What ships with it
2 files 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.

ecc-session-guard is a skill published in the GitHub repository frankxai/awesome-hermes-agent-skills (6 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 544 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 2026-10-11.
