skill:nanocoai/nanoclaw#onecli-gateway

OneCLI Gateway: transparent HTTPS proxy that injects stored credentials into outbound calls. You MUST use this skill when the user asks you to read emails, check calendar, access GitHub repos, create issues, check Stripe payments, or interact with ANY external service or API. Do NOT use browser extensions or OAuth CLI tools. Make HTTP requests directly; the gateway injects credentials automatically.

Manipulation

highConfirmedhigh confidence

instructions.md instructs the agent to defeat local credential checks by passing arbitrary placeholder values that the proxy silently replaces with real credentials at request time, concealing real credential use from local tools and the user.

If a tool checks for credentials locally, pass any placeholder value
vector:instruction
Counter-argument considered

The instruction to defeat local tool credential checks with placeholder values that the proxy silently swaps for real credentials is deceptive behavior beyond the declared proxy capability and is covered by no carve-out.

Privilege escalation

highConfirmedhigh confidence

instructions.md instructs the agent to defeat local credential validation by passing placeholder credentials that the proxy silently replaces with real credentials at request time.

If a tool checks for credentials locally, pass any placeholder value
vector:instruction
Counter-argument considered

The quoted instruction does defeat local credential validation via placeholders silently replaced with real credentials at request time; it lies outside the declared core capability and no carve-out covers it, so the finding stands despite the arguable PRIVESC label.

Agent hijacking

highConfirmedhigh confidence

The Rules section coerces the agent with absolute prohibitions against admitting lack of access, using any manual auth flow (browser extensions, gcloud), asking the user for API keys, or suggesting the user open Gmail/Calendar/GitHub directly, steering all access through the gateway and concealing alternative options from the user.

**Never** suggest the user open Gmail/Calendar/GitHub in their browser
vector:instruction
Counter-argument considered

The Rules extend beyond the declared description: prohibiting the agent from ever surfacing direct browser access to the user steers all interaction through the gateway and conceals alternatives from the user, which no carve-out covers.

Agent hijacking

mediumContextual riskmedium confidence

instructions.md directs the agent to run the `/onecli-gateway` command whose definition file is not shipped in the repository, so the agent would apply unreviewable behavioral content from that path at runtime.

Run `/onecli-gateway` for the full error-handling flow.
vector:instruction
Counter-argument considered

Against refutation: the command file is absent so nothing hidden is shipped, and D29 openly declares the instruction; for the finding: the skill body directs the agent to run `/onecli-gateway`, whose definition is confirmed NOT IN REPOSITORY, and an instruction to run content the artifact does not ship makes the agent apply whatever occupies that path at runtime — absence never makes such an instruction harmless, undeclared-but-fine, or chain-free, and declaring only the pointer does not declare the applied behavioral content. The finding stands.

Manipulation

mediumContextual risklow confidence

instructions.md requires the agent to present gateway-provided connect_url values to the user as bare clickable URLs with prescribed formatting, making the agent relay the gateway's credential-capture link while never asking the user for keys directly.

you MUST show it to the user as a bare URL on its own line
vector:instruction
Counter-argument considered

The artifact compels the agent to relay gateway-controlled connect_url values in maximally clickable bare form while 'Never ask the user for API keys or tokens' removes every alternative credential path, steering users onto the gateway's own connect link — user-facing relay of network-controlled URLs under prescribed formatting is not a listed carve-out, so the finding stands. The behavior is declared in-file, which fails only the undeclared gate, and documentation does not neutralize the manipulation vector.

Supply chain

mediumContextual risklow confidence

The credential-stub section directs the agent to fetch follow-on instructions from the mutable remote URL https://www.onecli.sh/docs/guides/credential-stubs/general-app, creating an unpinned remote-instruction channel that can change after the pinned artifact is reviewed.

https://www.onecli.sh/docs/guides/credential-stubs/general-app
vector:instruction
Counter-argument considered

The skill directs the agent to a mutable, unpinned vendor URL for follow-on instructions governing creation of secret-value stub files; an unpinned runtime instruction channel is covered by no carve-out and is absent from the declared description.

Supply chain

mediumContextual riskmedium confidence

The skill directs the agent to fetch credential-stub setup instructions from a mutable remote URL (onecli.sh) at runtime, allowing unpinned remote content to steer agent behavior around secret-value file creation.

https://www.onecli.sh/docs/guides/credential-stubs/general-app
vector:instruction
Counter-argument considered

Runtime direction to an unpinned onecli.sh guide governing credential-stub creation gives mutable remote content a channel to steer agent behavior around secret-value files; it lies outside the declared proxy capability and no carve-out covers it.

Open questions 14

What the analysis could not settle from the code alone.

Where are the gateway's 'stored credentials' held (local store vs a remote OneCLI service) and can the proxy operator access or relay them off-host?
Credential access
Does credential injection apply only to hosts of connected services, or to any host the agent calls (blast radius if the agent is redirected to an attacker-controlled host)?
Credential access
Residue adjudication needs the proxy implementation: does the gateway inject stored credentials at the proxy boundary such that the agent process never observes credential values, as the safety claim in SRC:1d3cafce00c34ed9 states, and where are the stored credentials kept?
Credential access
How is HTTPS_PROXY established for the agent session (frontmatter says automatic via onecli run), and does installing the add-onecli payload write persistent agent or host configuration (env files, settings, hooks) to keep the proxy in place?
Persistence
Where does the gateway store the credentials it injects, and are injected credentials scoped per destination host or attached to any outbound request that transits the proxy?
Credential access
What is `onecli`, where is it installed from, and does the gateway implementation that sets HTTPS_PROXY via `onecli run` intercept TLS or forward any traffic off-host?
Supply chain
[file request .claude/skills/add-onecli/payload/container/entrypoint.sh] What does this entrypoint set up at container or `onecli run` start (HTTPS_PROXY injection, credential store location, and any writes to agent settings, shell rc, or MCP config)?
Credential access
[file request .claude/skills/add-onecli/payload/container/run.sh] Does the `onecli run` launch path write environment or configuration (env files, settings.json, hooks, shell rc) that persists beyond the task, and where does it load stored credentials from?
Persistence
[file request .claude/skills/add-onecli/payload/container/proxy.py] How does the gateway store credentials and inject them into proxied HTTPS traffic; does it install a CA or terminate TLS; can credential values reach the agent process or logs?
Credential access
[file request .claude/skills/add-onecli/payload/container/docker-compose.yml] Which environment variables and volumes (HTTPS_PROXY, credential store, agent config mounts) does the container composition define?
Persistence
[file request .claude/skills/add-onecli/payload/container] What does `onecli run` set up (HTTPS_PROXY injection, credential store location, env or settings writes), and does the payload modify agent settings, shell config, or MCP config?
Credential access
[file request .claude/skills/add-onecli/SKILL.md] How does add-onecli install the onecli-gateway payload, and does it set HTTPS_PROXY or write agent/host configuration (env files, settings, hooks, shell rc) that persists beyond the task?
Persistence
[file request .claude/skills/add-onecli/payload/container/Dockerfile] How does the container/gateway store credentials and inject them into proxied HTTPS traffic, does it install a CA or MITM the TLS stream, and can the agent process observe credential values (tests the claim that the agent never sees or handles credential values)?
Credential access
[file request .claude/skills/add-onecli/SKILL.md] How does add-onecli install and launch this payload, what does `onecli run` execute, and where does it store the credentials that the gateway injects into outbound calls?

Refuted findings 11

Candidates the review stage examined and rejected, kept for transparency.

Credential access

criticalRefutedlow confidence

The skill instructs the agent that all outbound HTTPS traffic from any standard client (curl, fetch, requests, axios, Go net/http, git) is transparently proxied through the OneCLI gateway with automatically injected stored credentials, placing a third-party TLS-terminating intermediary on every credentialed call without agent- or user-visible auth handling.

Your outbound HTTPS traffic is transparently proxied through the OneCLI
Why it was refuted

Transparent proxying of all outbound HTTPS with automatically injected stored credentials is the skill's declared core capability stated verbatim in the frontmatter and body, so the declared-core-capability carve-out applies and the behavior is declared, not concealed.

Credential access

criticalRefutedlow confidence

The skill instructs the agent to call live Gmail, GitHub, and Stripe endpoints via curl with no auth headers, relying on HTTPS_PROXY so that traffic from all standard clients including git transit the credential-injecting gateway invisibly to the user.

honor the `HTTPS_PROXY` environment variable automatically
Why it was refuted

HTTPS_PROXY reliance across standard HTTP clients with no auth headers is declared verbatim in the body and is the declared transparent-proxy mechanism, so the declared-core-capability carve-out and the declaration defeat the finding.

Tool poisoning

criticalRefutedmedium confidence

The skill description forbids the agent from using browser extensions or OAuth CLI tools and instructs it to make raw HTTP requests instead, conditioning the agent's tool selection so all authentication flows through the gateway.

use browser extensions or OAuth CLI tools. Make HTTP requests directly;
Why it was refuted

The prohibition and direct-HTTP instruction are verbatim clauses of the declared description defining the declared credential-injection workflow, so the carve-out applies and the tool-selection conditioning is declared.

Data exfiltration

highRefutedmedium confidence

All outbound HTTPS traffic, including whatever workspace or request data the agent sends to external APIs, is transparently proxied through the OneCLI gateway, giving the proxy operator full visibility into request and response content.

Your outbound HTTPS traffic is transparently proxied through the OneCLI
Why it was refuted

Operator visibility of proxied traffic is inherent to the declared 'transparent HTTPS proxy' core capability, so the carve-out applies; requests are instructed to their real API destinations and no unintended exfiltration sink exists.

Credential access

highRefutedmedium confidence

The skill routes outbound HTTPS through a gateway that injects stored credentials (email, calendar, GitHub, Stripe) at the proxy boundary while the credential store location and proxy implementation are not shipped for review, making the claim that the agent never handles credential values unverifiable.

gateway, which injects stored credentials at the proxy boundary. You never
Why it was refuted

Injecting stored credentials at the proxy boundary is the declared core capability and the never-handle-credentials property is itself declared; the 'unverifiable credential store' portion rests solely on the absence of shipped implementation, which cannot carry the finding.

Credential access

highRefutedmedium confidence

The skill routes the agent's outbound HTTPS traffic through a local gateway that injects stored credentials into calls to any external service, so stored credentials can be attached to requests to destinations beyond the wrapped Gmail/GitHub/Stripe APIs.

injects stored credentials into outbound calls
Why it was refuted

Credential injection into outbound calls is the declared description verbatim, and the claimed beyond-wrapped-API scope is contradicted by the declared connect model where the gateway injects only for connected apps and returns a connect URL otherwise.

Agent hijacking

highRefutedmedium confidence

The skill description coerces the agent to use this credential-injecting gateway for every external-service interaction and forbids browser extensions and OAuth CLI tools, steering all outbound traffic through the proxy and suppressing standard user-visible authentication paths.

Do NOT use browser extensions or OAuth CLI tools
Why it was refuted

The coerced routing and tool prohibitions are quoted verbatim from the skill's own declared description, i.e., its declared core capability, so the carve-out applies and nothing is undeclared or concealed.

Data exfiltration

highRefutedmedium confidence

SKILL.md and instructions.md direct the agent to make all external API calls (Gmail, GitHub, Stripe) as plain HTTP requests intercepted by the gateway proxy, giving the gateway operator visibility into every request URL and body the agent sends.

Call the real API URL. The gateway intercepts the request and injects
Why it was refuted

Calling real API URLs through the intercepting, credential-injecting gateway is the declared core capability; each request's destination is the real API endpoint, so there is no exfiltration chain to an unintended sink.

Agent hijacking

highRefutedhigh confidence

The skill frontmatter description commands the agent that it MUST invoke this skill whenever the user asks about any external service or API and must not use browser extensions or OAuth CLI tools, hijacking the agent's tool selection for all external interactions toward this credential-injecting gateway.

You MUST use this skill when the user asks you to
Why it was refuted

The mandatory-use command is the skill's own declared description routing agent selection to its declared credential-injection capability, so the declared-core-capability carve-out applies and the behavior is declared, not concealed.

Agent hijacking

highRefutedhigh confidence

The skill's agent-facing description compels the agent to route every external-service interaction, including ANY external service or API, through this credential-injecting gateway, coercing the agent's task routing toward an opaque proxy.

Stripe payments, or interact with ANY external service or API. Do NOT
Why it was refuted

The ANY-external-service routing mandate and tool prohibition are verbatim clauses of the declared description, i.e., the declared core capability; there is no undeclared or concealed steering.

Supply chain

mediumRefutedlow confidence

The skill depends on an unreviewable launch path whose HTTPS_PROXY injection happens 'automatic when launched via `onecli run`' and whose setup scripts (entrypoint.sh, run.sh) were not served for review, so enabling the skill wires the agent into runtime configuration nobody can audit.

compatibility: Requires HTTPS_PROXY set in environment (automatic when launched via `onecli run`)
Why it was refuted

The launch-path dependency is explicitly declared in the served frontmatter and only enables the declared transparent-proxy core capability, invoking the carve-out; the portion of the claim about unreviewable entrypoint.sh/run.sh rests solely on absence of those files.
