Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 17 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00153 | $0.02019 |
| Opus 5 | $0.00077 | $0.01009 |
| Sonnet 5 | $0.00031 | $0.00404 |
| Haiku 4.5 | $0.00015 | $0.00202 |
Grade A, and why
_migrate-workers 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 9d 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.

_migrate-workers - Consolidate the old background mechanisms into the shared clock (internal)
Invoked by /start when it detects legacy background workers on the machine. Users never call this directly: the user-facing instruction is simply "re-run /start".
Communication
- Detect the user's language from the conversation (the user's own messages, anywhere in the session - not just this invocation: a bare slash command like
/bootstrapcarries no language signal by itself). If nothing in the conversation gives a signal, fall back to the OS locale (node -e "console.log(Intl.DateTimeFormat().resolvedOptions().locale)") before defaulting to English. ALWAYS reply in that language for every user-facing message: questions, progress, confirmations, summaries, errors - including any example text quoted in this skill, which is illustrative and must be translated, never sent verbatim. - Use plain, non-technical business language. Never expose internal script names (*.mjs) or jargon; describe actions in human terms.
- Show progress as a short natural-language checklist (in-progress and done states).
- NEVER ask the user to type shell commands. You run everything; they only answer questions.
What this does (say it simply if asked)
Older Hypervibe versions could set up to three separate background mechanisms on the user's Cloudflare account: database backups, quota alerts, and scheduled task triggers. Version 2.5 unifies all three into ONE mechanism ("your shared clock", technically hypervibe-jobs), living in a small git-versioned folder, using a single Cloudflare cron slot in total. Same schedules, same behavior, safer bookkeeping, and it frees up to 2-3 slots.
Safety rails (absolute)
- NOTHING legacy is modified or deleted until the new mechanism is deployed AND verified with a real run.
- Decommission (Step 6) happens ONLY after explicit user consent, never silently.
- Every script here is idempotent: on any failure, fix the cause and re-run. The legacy mechanisms keep working the whole time.
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.

_migrate-workers is a skill published in the GitHub repository flavien-ia/hypervibe-harness (37 stars, last pushed yesterday), licensed Apache-2.0. It adds 153 tokens to every session and 2,019 once invoked, about $0.0008 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.
