Persistent shared memory for AI coding agents that turns a folder of markdown files into searchable memory across sessions, repos, and machines.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
43/43 tools missing one or more hints — vault_agent-journal (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); vault_agent-memory (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); vault_bootstrap-repo (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +40 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Shell command execution
3 child_process/subprocess calls in production code — runs shell commands (src/core/curate-git.ts:37, src/core/subagent-intent.ts:69, src/core/subagent-intent.ts:82)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — hono@4.12.15 (high), js-yaml@3.14.2 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
2/17 production deps stale: pngjs@2023-02-20 (3.5y), gray-matter@2023-07-12 (3.1y)
Domain consistency
