lykos@0.0.1
CAUTION· install onlyPublisher claims: "Serves an orchestrating agent over stdio, letting it start background coding sessions without waiting, check their status, steer or stop them, and call specialists as its own tools. Results distinguish work that was actually verified from what the worker merely claims." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Nothing executable in the bundle ran; the trace covers the install step only.- Tested
- every file read, file written and host contacted by what ran
- Not tested
- use of the skill by an agent
What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.
Before you give it your token
- It will ask for
GIT_AUTHOR_EMAILGIT_AUTHOR_NAMESCHEMA_TOKENS_BASISConfiguration, not credentials: BUDGET_KEYS, COLUMNS, EVAL_PYTHON_CONFIG_KEY, GIT_COMMITTER_EMAIL, GIT_COMMITTER_NAME, LINES, LYKOS_ASK_OUTCOME, LYKOS_BUDGET_PER_DAY_USD, LYKOS_BUDGET_PER_RUN_USD, LYKOS_COMPACTION_THRESHOLD, LYKOS_HUD, LYKOS_LEDGER_PATH, LYKOS_MODEL_DEFAULT, LYKOS_OUTPUT_DIET, LYKOS_PROMPT_DIET, LYKOS_TRUST_WORKSPACE, LYKOS_UI_THEME- Where it talks to
- no vendor host named in the code
- What the honeypot saw
- no credential files read · no network
- What we could not test
- use of the skill by an agent
Connect it with a scoped credential, under the guard. It asks for GIT_AUTHOR_EMAIL, GIT_AUTHOR_NAME, SCHEMA_TOKENS_BASIS and talks to its vendor. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind. What the tools do with a real credential was not observed.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-12 and scored it 78/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Privileged sudo command; Privileged sudo command. Summary: no network, touches nothing outside the project, writes no memory.
