Mutation slice 2 scored 0% before this, and the reason was blunt: **the exec allowlist had no test whatsoever.** The clipboard restriction could be inverted, weakened, or deleted outright and the suite stayed green. That control matters because the clipboard is readable by every process in the session. A token restricted to `cat` that may still reach the clipboard is not restricted to anything — the holder simply copies the secret out, and the allowlist looks enforced while containing nothing. Now tested: a command-restricted token is refused the clipboard, a token with no allowlist is not (so the rule is conditional rather than a blanket ban passing as one), an allowlisted command is permitted, and one outside the list is refused without the sink ever running. **A fail-open found while triaging one of the survivors.** An empty `exec_allowlist` was DROPPED at issue time, which made the token unrestricted. Automation that computes an allowlist and arrives at zero entries means "permit nothing" and was silently handed "permit everything" — a fail-open in the one field whose entire purpose is restriction. It is now refused at issue time with an error saying which of the two readings the caller probably wanted. Reachable only over the raw socket protocol, since commander requires at least one value. **An audit-accuracy gap.** A denial and a missing entry deliberately return the SAME message, so the response cannot be used to enumerate ids — the audit log is where the difference is supposed to be recorded, and nothing read it. The two reasons could be swapped with every test passing. Testing it needed two corrections of my own: the CLI resolves references locally so the request never reaches the daemon, and the shared token in that file is revoked by an earlier test, so both calls were refused at the token check instead. It also needed a stronger assertion than the one I first wrote — checking that both reasons merely APPEAR passes when they are swapped, which is exactly the mutation. It now asserts the pairing: which id got which reason. Three survivors are recorded as genuinely unkillable with reasons, rather than chased: the two `length > 0` comparisons cannot differ from `>= 0` now that an empty allowlist cannot be stored, and the capability early-return is redundant with the length check below it. agent slices 1-2 (mutants 1-16): 100% of viable mutants caught.

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.
