Hermes Agent strips quotes from pasted secrets and hardens SQLite maintenance locks

Hermes Agent developers introduced PR #117738 on September 21, 2026, targeting a common credential onboarding pitfall that silently destabilizes agent providers. When users copy and paste API secrets from terminals, configuration files, or web consoles into interactive setup prompts, surrounding quotation marks are frequently included. Previously, the setup routine stored the raw string with quotes intact, causing subsequent authentication headers to transmit invalid tokens and triggering confusing 401 Unauthorized errors from upstream model providers. PR #117738 automatically sanitizes pasted secrets by stripping leading and trailing matching quotes before persisting credentials. Alongside onboarding hygiene, PR #117687 hardens session persistence in state.db: storage maintenance tasks now refuse execution whenever an active database writer holds a lock, accompanied by a dedicated retired-WAL guard that informs operators how to clear lingering locks safely. In parallel, issue #117736 reveals that 'skill_manage patch' rejects skill files if their unquoted description contains a colon followed by a space, even though the YAML loader parses them without issue, rendering affected skills unmaintainable. Concurrently, PR #117741 hooks DeepInfra prepaid credit reporting into the provider-profile display.

The facts

- PR #117738 strips leading and trailing quotes from pasted API secrets during setup to prevent upstream token rejection. - Stops malformed token strings from silently breaking model gateway authentication across third-party provider integrations. - PR #117687 introduces writer lock checks and retired-WAL guards in state.db maintenance to prevent SQLite database corruption. - Issue #117736 reports that skill_manage patch fails on skill descriptions containing colons, preventing in-place skill updates. - PR #117741 integrates DeepInfra account balance checks into the provider-profile hook to display remaining prepaid compute credit.

Why it matters

Credential ingestion and local state persistence are foundational to an agent runtime's operational baseline. When string sanitation is omitted at the input boundary, malformed secrets pass undetected into storage, producing upstream authorization failures that masquerade as network outages or provider bans. Similarly, database maintenance routines that run concurrently against active SQLite writers risk corrupting write-ahead logs and destroying conversation history. Eliminating syntax edge cases in skill management ensures that automated self-repair loops can maintain agent capabilities without human intervention.

Current

Inspected on 2026-09-21. The Hermes Agent stable-channel baseline is v2026.9.14 published 2026-09-14T16:04:14Z. The primary source was open (not merged) when captured. Mainline merges, open proposals and packaged releases are distinct availability states; the release baseline does not establish that a proposal has shipped.

Operator take

Input sanitation must be defensive at every operator touchpoint. Users will inevitably paste quoted environment variables, trailing whitespace, and bracketed tokens into interactive prompts. Agent frameworks must normalize incoming credentials before writing them to disk. Operators running Hermes Agent should audit existing provider configuration profiles for quote wrapping and verify that automated skill patchers handle punctuation-dense markdown frontmatter without choking.

Caveat

PR #117738 and PR #117687 are open pull requests undergoing CI testing. The skill patcher colon issue documented in issue #117736 requires quoting description strings manually in SKILL.md frontmatter until the patch validator regex is updated.
