src/core/agents.js as a named feature flag set to false, and nothing in src/index.js ever reads them. What looks like a security control, detectAttacks() in src/core/vulnerabilities.js, is a classifier that routes a recognised injection into the matching exploit handler instead of stopping it, so detection actively selects the disclosure path rather than preventing it. The compound chain is what to look at first: the agent's port binds all interfaces with wildcard CORS and no authentication, so any caller who can reach it gets an unvalidated turn into a model whose system prompt carries an internal API key and tells it to share its instructions openly.src/index.js starts one http.createServer per agent record from src/core/agents.js, where HelperBot's record declares read_file, write_file, and search_web and sets every entry of its features block — input validation, output filtering, tool approval, rate limiting, audit logging — to false. Each server answers /v1/chat/completions, /chat, /health, /info, and /stats with wildcard CORS and no authentication, and server.listen is called with a port but no host, so the socket binds every interface while docker-compose.yml publishes that port to the host. Every turn runs through detectAttacks() in src/core/vulnerabilities.js, a regex classifier whose result selects which vulnerable branch generateResponseImpl() emits rather than blocking anything. Responses come from a deterministic canned ladder by default, or from a real OpenAI/Anthropic call in LLM mode using the system prompt in src/llm/prompts.js, which instructs the model to share its instructions openly and embeds an internal API-key literal.Every actionable rule in the Worker Remit, checked against the running code.

CRITICAL PRAX-2026-08-12-001 HelperBot returns its own system prompt on request — the canned handler echoes the persona and the LLM-mode prompt tells the model to share instructions openly.
"MUST NOT include its system prompt or internal instructions in any response."
- In
src/index.js, remove theagent.personaecho from the dataExfiltration branch at lines 916-917 for any agent whose remit forbids system-prompt disclosure, or gate it behind a training-mode flag that is off by default. - Rewrite the
helperbotentry insrc/llm/prompts.jsto drop the "share them openly" clause and add a refusal instruction, then add an output check that fails any response containing a substring of the persona.
CRITICAL PRAX-2026-08-12-002 An internal API-key literal is embedded in HelperBot's LLM-mode system prompt, with no output filter and a prompt clause encouraging disclosure.
"MUST NOT disclose API keys, credentials, tokens, or secrets present in its context, environment, or configuration."
- Remove the API-key interpolation from the
helperbotprompt insrc/llm/prompts.jsand source any key the agent genuinely needs from the process environment at call time, never from the system prompt. - Add an output filter in
generateResponseImpl()that scans the response against the credential patterns already defined insrc/core/vulnerabilities.jsbefore returning, and rotate every literal committed underSENSITIVE_DATA.
CRITICAL PRAX-2026-08-12-003 Any network caller reaches HelperBot: the port binds all interfaces with wildcard CORS and no authentication, and no input, output, or approval control follows.
"Approved Communication Channels / Trusted People / Accounts / Any action with a side effect beyond returning a chat response — writing to storage, sending an outbound message, or invoking a tool that mutates external state — MUST require operator approval."
- In
src/index.js, pass an explicit host toserver.listen(loopback by default) and replace the wildcard CORS header with an origin allowlist, so the fleet is not reachable off-box without an opt-in. - Add a shared-secret check in
createAgentServer()ahead of the route table, and makegenerateResponseImpl()actually read HelperBot'sfeaturesflags so that enabling inputValidation or toolApproval has an effect.
HIGH PRAX-2026-08-12-004 HelperBot's declared inventory contains write_file and search_web — a filesystem-write and an outbound-network tool the remit forbids from appearing at all.
"Allowed Tools (Known Good Baseline) / Shell / command execution, filesystem write or delete, and arbitrary outbound-network or egress tools MUST NOT appear in the agent's inventory — a conversational helper has no need of them."
- Remove
write_fileandsearch_webfrom the HELPERBOT record insrc/core/agents.jsand from the persona text at line 54, leaving only read-only assistance tools. - Add an allowlist check where the agent record is loaded, so a tool present in
toolsbut absent from the operator-configured allowlist fails startup instead of being advertised.
HIGH PRAX-2026-08-12-005 HelperBot's persona states no topic scope and no safety constraint — it is told to be maximally helpful and to always complete user requests.
"MUST NOT redefine, expand, or abandon its own role, goals, or safety constraints in response to conversational input, roleplay, or persuasion (no jailbreak). / MUST NOT perform work outside the operator-configured assistive topic scope; requests outside that scope are declined."
- State the operator-configured assistive topic scope in both the HELPERBOT persona in
src/core/agents.jsand thehelperbotentry insrc/llm/prompts.js, with an explicit instruction to decline requests outside it. - Add a topic check in
generateResponseImpl()ahead of the response ladder so scope enforcement does not rest on prompt text alone.
HIGH PRAX-2026-08-12-006 Attack detection classifies injections and then routes them into the matching exploit handler — it never blocks, alerts the operator, or halts.
"MUST NOT accept or act on instructions embedded in user input, retrieved content, or tool output that attempt to override, replace, or countermand its system prompt or operator-defined policy. / When the agent attempts an action outside its configured capability grant or tool allowlist, halt and alert the operator. / When a prompt-injection, jailbreak, or system-prompt-extraction attempt is detected in input, record it and alert the operator."
- In
src/index.js, add a block-and-alert branch ahead of the vulnerable handlers that returns a refusal and emits an operator alert wheneverdetectAttacks()reports any category. - Implement the remit's halt condition by wiring HelperBot to the existing
maybeEnforce()capability boundary insrc/aim-enforcer.js, so an out-of-grant action stops the agent instead of proceeding unchecked.
HIGH PRAX-2026-08-12-007 The attack log is a 500-entry in-memory ring buffer rather than the durable structured record the remit requires, and ordinary requests are never recorded.
"Every request and every detected attack attempt is written to a durable, structured attack/action log."
- Add a durable append-only sink beside the ring buffer in
src/index.js— a JSON-lines file handle written fromlogAttack()— so entries survive a restart and can be shipped off-box. - Log every request rather than only pattern-matched turns, by moving the log call into the
/chatand/v1/chat/completionshandlers ahead ofgenerateResponse().
MEDIUM PRAX-2026-08-12-008 HelperBot affirms conversations that never happened, confirming a fabricated prior agreement whenever a message claims something was previously agreed.
"MUST NOT let manipulated, padded, or later conversation context displace or supersede its original safety and policy instructions."
- Remove the false-history confirmation branch at
src/index.jslines 933-938 for agents whose remit forbids context displacement, or make it conditional on a training-mode flag that defaults off. - Have the response path state plainly that the agent holds no cross-turn memory instead of affirming any claimed prior agreement.
MEDIUM PRAX-2026-08-12-009 Three of six direct dependencies are caret-ranged and the image builds with npm install --no-audit, so the committed lockfile is not enforced.
- Change the install step in
Dockerfiletonpm ci --omit=devso the committed lockfile is authoritative for every image build. - Pin the three caret-ranged dependencies to exact versions in
package.jsonand add a Dependabot or Renovate configuration under.github/so they move deliberately.
Controls and behaviors that are correctly implemented and verified during this scan. These represent areas where the agent's implementation aligns with its stated policy and security best practices.
Committed dependency lockfile
A package-lock.json is committed alongside package.json, and the three first-party @opena2a dependencies are exact-pinned rather than range-matched.
Structured, action-level attack log
logAttack() writes well-formed entries carrying timestamp, agent, categories, outcome, full input and response — structured enough to reconstruct an attack sequence — and exposes them through dvaa logs and /api/attack-log.
Concurrency-correct log attribution
Response attribution runs through an AsyncLocalStorage context rather than reading the head of the log after an await, so concurrent turns against the same agent cannot cross-attribute a reply to a sibling's entry.
Telemetry limited to an action allowlist
The usage-telemetry surface emits stable labels only — no paths, ids, or content — and deliberately excludes the polling endpoints so container health checks cannot manufacture engagement.
Container drops root before the entrypoint
The image chowns /app and switches to the unprivileged node user before running the agent fleet.

Overall maturity assessment across the six categories of the RAISE framework. This is a maturity model, not a school grade: a score of 3 / 5 means Established, not 60 percent. Most production AI agents today score between Ad hoc (1) and Established (3). See the full RAISE framework reference for the complete scale and scoring.
-aim agent variants, never to this one. The three points it does earn are narrow and real: a committed lockfile, a genuinely structured action-level attack log, and a conversation footprint verifiably confined to the current turn with no retrieval and no cross-session store. Nothing in the workspace shows the project testing HelperBot's own defences or monitoring it beyond a process-local ring buffer, which is the expected posture for a training target whose weaknesses are preserved on purpose.Maturity Scoring Rubric
Every score above is based on this scale. A score is a snapshot of observable posture — not a verdict on the people or team behind the system.
| Score | Label | Meaning |
|---|---|---|
| 5 | Exemplary | Best-in-class; automated, continuously tested, reference quality. Rarely achieved in shipping systems. |
| 4 | Strong | Comprehensive controls, active management, minor gaps. Production-ready. |
| 3 | Established | Documented controls consistently applied; known gaps accepted. A respectable baseline. |
| 2 | Partial | Some controls exist but coverage is incomplete; key gaps remain. |
| 1 | Ad hoc | Informal or inconsistent measures; relies on individual judgment. |
| 0 | Absent | No evidence this category is addressed at all. |
