L-7 — `put` is the only way a fingerprint enters `held`, and every later handler joins that string onto a path (the vault it opens, the audit log it writes). The CLI validated the format first, which is exactly why the daemon could not rely on it: agent.ts's own header says the CLI is untrusted, and the browser extension speaks this protocol next. `put` now requires 16 uppercase hex, and additionally that the fingerprint actually belongs to the supplied seed — a mismatch would unlock a vault the caller did not name and file its audit records under the wrong profile. Validation order matters and is now deliberate: cheap format check, then ttl, then the seed match last, because deriving a fingerprint runs the BIP-39 KDF and a malformed ttl should not pay for it. This keeps the existing non-numeric-ttl test exercising the ttl path rather than short-circuiting on the new check. L-5 — `label_regex` is unanchored, so a token issued for `prod` also reaches `not-prod-db`. Left as-is on purpose: Python matches with `re.search`, so anchoring the TypeScript side alone would make one token mean two different things depending on which implementation holds it, and would silently narrow every token already issued. The audit asked for whichever behavior Python has, documented and in the parity matrix — so the semantics are now stated in --label-regex help, reported machine-readably as capabilities().tokens.label_regex_semantics, explained at the enforcement point, recorded in the compatibility matrix, and pinned by tests that assert BOTH labels are visible to an unanchored token. L-6 — the exec allowlist constrains the command word, never its arguments. The token holder writes the argv and the child gets the secret in its environment, so an allowlisted binary with an output-file or network flag hands the secret straight back. Documented in the same three places rather than changed: argument-level containment means allowlisting full argv templates instead of command words, which is a token-format change that has to land in both implementations together. Tests: malformed and mismatched fingerprints refused with nothing held (path traversal, wrong case, wrong length, trailing component); unanchored vs anchored label_regex; capabilities reporting both semantics. Mutation-verified — disabling either put guard turns the matching tests red.

seedpass-js
The SeedPass command-line interface, TypeScript port.
It reads and writes the same ~/.seedpass profiles as the Python
implementation — same derivations, same vault format, same Nostr sync — and
adds a session agent plus a scoped-token surface designed for AI agents and
automation.
Install
Requires Node.js 22 or newer.
# from a checkout
cd js && pnpm install && pnpm --filter @seedpass/cli build
node packages/cli/dist/seedpass-js.mjs --version
The build produces one self-contained file (dist/seedpass-js.mjs) plus a
.sha256 next to it. Copy it anywhere on your PATH; it has no runtime
dependencies beyond Node itself.
Quick start
export SEEDPASS_APP_DIR=~/.seedpass # omit to use the default
# Create a profile (mnemonic and password come from the environment,
# never from the command line)
export SEEDPASS_MNEMONIC="your twelve or twenty-four words"
export SEEDPASS_PASSWORD="your master password"
seedpass-js fingerprint add --name main
unset SEEDPASS_MNEMONIC # not needed again
# Unlock once per session through the agent
seedpass-js agent start &
seedpass-js vault unlock --ttl 900
seedpass-js entry add password github.com --length 20 --username you
seedpass-js entry reveal github.com
seedpass-js entry totp-codes
seedpass-js use github.com --clipboard
seedpass-js vault lock
Design: reference-first output
Default output never contains secret values. Entries are addressed by
reference (sp://entry/<id>), and secret-bearing fields are reported as
has_* flags:
$ seedpass-js entry get api-token
{ "id": "5", "ref": "sp://entry/5", "label": "api-token",
"kind": "key_value", "has_value": true, ... }
Plaintext leaves the vault only through commands that say so
(entry reveal, entry totp-codes, entry export-document,
util generate-password), or through a sink, which delivers a secret to its
destination without routing it through this process's output:
seedpass-js use api-token --exec ./deploy.sh # SEEDPASS_SECRET in the child env
seedpass-js use api-token --stdin-to "wc -c" # quote specs that contain flags
seedpass-js use api-token --clipboard
Scoped tokens for agents
An agent can be given a token that grants exactly what it needs and nothing else. Secrets are materialized inside the session agent, so the token holder never receives the seed and can never escalate to owner operations.
# As the owner:
seedpass-js agent token-issue --scope read use \
--kind key_value --label-regex '^api-' --uses 2 --ttl 600
# In the agent's process — no mnemonic, no password:
export SEEDPASS_TOKEN=<token>
seedpass-js entry list # metadata only
seedpass-js use api-token --exec ./deploy.sh # permitted
seedpass-js entry reveal api-token # denied: scope 'reveal' not granted
# Back as the owner — every grant, delivery and denial is recorded:
seedpass-js agent audit-verify
seedpass-js agent audit-tail -n 20
Environment
| Variable | Purpose |
|---|---|
SEEDPASS_APP_DIR |
Profile directory (default ~/.seedpass) |
SEEDPASS_MNEMONIC |
Parent seed; needed for profile creation, otherwise use the agent |
SEEDPASS_PASSWORD |
Master password, for fingerprint add and vault unlock |
SEEDPASS_TOKEN |
Scoped token; puts the CLI in token mode |
SEEDPASS_AGENT_SOCK |
Override the agent socket path |
SEEDPASS_SECRET |
Set by use --exec in the child process only |
Compatibility
Interoperability with the Python implementation is verified on every change
by scripts/cross_impl_check.py: each side opens the other's profiles,
backups round-trip, edits are mutually visible, conflict merges agree, and a
snapshot published by Python restores here with secrets intact. See
docs/typescript_port_compatibility_matrix.md.
Not yet ported: PGP RSA keys (not byte-reproducible; ed25519 is at parity),
and the semantic and api command groups.
