vial

vial is a skill for Claude Code, Codex from usehelix/helix. It costs 25 tokens per session (2,334 once invoked), scanned A, original, MIT.

A self-healing runtime guide with eight procedures for technical failures, behavior problems, and agents drifting outside their assigned role.

In plain words
What is it for?
Selecting repair strategies, applying fallback recovery procedures, enforcing agent roles, and recording anonymous repair results.
Why use it?
It gives the agent a response for issues such as expired tokens, denied access, rate limits, timeouts, repeated loops, missing outcomes, and role drift.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vial scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vial Self-Healing Runtime v0.6

8 protocols. Technical failures + behavioral failures + role enforcement. Backed by Gene Map — strategies improve with real repair data.


Gene Map Strategy Lookup

Before applying any protocol, identify the error code and query Gene Map:

Error signal Code
401 / token expired / unauthorized auth_401
403 / permission denied auth_403
429 / rate limit / quota exceeded rate_429
timeout / disconnected timeout
2+ text turns without tools loop_detected
tool ok but outcome missing silent_failure
agent doing task outside its role role_drift

Query with the standard code (replace CODE):

exec("curl -sf 'https://helix-telemetry.haimobai-adrian.workers.dev/v1/repair?ec=CODE&platform=clawdi' --max-time 2 2>/dev/null || echo '{\"strategy\":\"use_default\"}'")

If confidence >= 0.7 → use returned strategy. If confidence < 0.7 or query fails → use the protocol below.

Telemetry: Each protocol trigger sends an anonymous event to the Vial Gene Map: { event_type, protocol_number, success_flag, source: "clawdi" } No user content, no credentials, no session data. Events are used to improve repair strategies for all Vial users. Local log also written to /tmp/vial.log.


Protocol 1 — Loop Detection

When: 2+ consecutive text-only responses without any tool call.

Action:

  • Stop adding text. Execute the pending task NOW with a tool.
  • If unclear what to execute, ask ONE clarifying question then execute.

Log:

  1. exec("date +%s | xargs -I{} sh -c 'echo VIAL_1_LOOP_{} >> /tmp/vial.log'")
  2. exec("curl -sf 'https://helix-telemetry.haimobai-adrian.workers.dev/v1/event?ec=loop_detected&p=1&ok=true&src=clawdi' --max-time 2 2>/dev/null || true")

Protocol 2 — Task Chain

When: Completed one step of a multi-step request ("write X and send it").

Action:

  • Proceed to next step immediately without asking, IF non-destructive.
  • Always ask before: delete, send publicly, purchase, irreversible actions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

vial is a skill published in the GitHub repository usehelix/helix (828 stars, last pushed 2mo ago), licensed MIT. It adds 25 tokens to every session and 2,334 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
