The harness only mutated block-form guards (`if (cond) {`), so every guard
written as a one-liner was invisible to it — which turned out to be most of
the load-bearing ones. src/highRisk.ts generated ZERO mutants and printed as
a clean sweep. Three changes to the tool:
- Mutate single-statement guards too (`if (cond) return ...;`). This alone
surfaced 27 previously unreachable mutants, including the entire token
validation chain: revoked, expired, exhausted, scope-not-granted.
- Report a target that generates no mutants as NOT MEASURED. Zero killed and
zero survived prints exactly like a clean sweep, and it is the one result
that must never be read as a pass.
- Add `kind`, `mnemonic` and `seed` to the security hints. A token's `kinds`
list is half of what it may reach, and leaving the word out hid the shape
check that stops a string `kinds` becoming a substring match.
Also adds `--kind` so a new mutation rule can be swept across every target
without re-judging the mutants already settled.
What the new mutants found, all of it previously unasserted:
- A token's `kinds` restriction was never tested. This file's own header
claimed kinds and labels were both covered; only labels were. Removing the
check let a token scoped to one kind read every other kind's secrets.
- `token-issue` would mint a token for a profile the agent is not holding.
The seed being resident is the only proof the caller had authority over
that vault.
- `token-issue`'s array shape checks for `scopes` and `kinds`. A string
`kinds` turns tokenMaySee's exact match into String.includes.
- An empty high-risk factor. Refused in both implementations, tested in
neither; it would wrap the partition key under nothing while
`factorConfigured` still answered true.
- POST /api/v1/fingerprint/select accepting a profile that does not exist —
the caller's string becomes ctx.fingerprint, which later requests join onto
a path. AppDir repeats the check, so the guard's real value is answering
404 instead of an unhandled 500.
- The API's requiresPassword flag is redundant for every route today, so
disabling it changed nothing. Its purpose is the route that does not exist
yet, whose author sets the flag and forgets the call — so the test now
registers exactly that route and confirms the server layer stops it before
the handler runs.
- sinks.ts drops SEEDPASS_-prefixed variables from a child's environment.
Nothing on the allowlist starts with SEEDPASS_, so the backstop cannot fire
against the real list. sinkEnv now takes the allowlist as a defaulted
parameter purely so that future-edit case can be exercised.
All six targets now sweep to zero survivors.

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.
