In plain words
What is it for?

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.

Security

Grade A, and why

hermes-memory 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 1mo 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

Hermes Memory Rule

Before making code changes, read hermes/retrieval/index.md and any referenced Hermes memory files relevant to the task.

For every meaningful requirement, bugfix, investigation, refactor, deployment, or review task:

  1. Create or update a task record under hermes/tickets/.
  2. Record context, goal, changed files, behavior changes, verification, and follow-ups.
  3. For bugfixes with a useful root cause, create or update hermes/memory/bugs/.
  4. For durable feature behavior, create or update hermes/memory/features/.
  5. For architecture or technical decisions, create or update hermes/memory/decisions/.
  6. Update hermes/memory/core/current-state.md when project status, active problems, or next steps change.

Before claiming completion, verify that code changes, tests/checks, ticket updates, and relevant Hermes memory updates are all closed.

Do not use the legacy docs/ directory as the Hermes memory root. Hermes memory belongs under hermes/.

Changes

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.
