In plain words
What is it for?
Use it to register bugs, feature requests, maintenance work, or refactoring tasks in the project backlog.
Why use it?
It captures the observed symptom and assigns suitable priority and issue type without prematurely designing a solution.

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

add scanned grade A with 0 findings 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 7d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/add - Register Issue

Register a problem as a viban issue. No codebase exploration, no solutions — symptoms only.

CLI only (no direct viban.json access)

Input: $ARGUMENTS

Step 1: Clarify (only if vague)

If clear enough (who/what/where), skip to Step 2. Otherwise, one AskUserQuestion:

  • header: "Problem", question: "Can you describe the symptom more specifically?"
  • options: context-appropriate (e.g. "Error/crash", "Feature not working", "Performance issue", "Let me describe")

Step 2: Priority & Type

Infer from description. Don't ask unless truly ambiguous.

Priority Condition Type When
P0 System down, data loss bug Something broken
P1 Feature broken, errors feat New functionality
P2 Performance, warnings chore Maintenance, config
P3 Improvements, refactoring refactor Code restructuring

Step 3: Issue Numbering

[ -f ".viban/workflow.md" ] && cat ".viban/workflow.md"
  • Workflow says Manual → ask user for external ID (e.g. PROJ-42)
  • Auto or no workflow → let viban auto-assign
  • ID in $ARGUMENTS → use it regardless

Step 4: Register

mkdir -p .viban/tmp
cat > .viban/tmp/desc.md <<'VIBAN_EOF'
## Symptoms
{one-sentence symptom}
{additional context, if any}
VIBAN_EOF

# Auto numbering (default)
viban add "{title}" --desc-file .viban/tmp/desc.md --priority {priority} --type {type}
rm -f .viban/tmp/desc.md

# Manual numbering (when workflow specifies)
viban add "{title}" --desc-file .viban/tmp/desc.md --priority {priority} --type {type} --ext-id "{external_id}"
rm -f .viban/tmp/desc.md

Use <<'VIBAN_EOF' (quoted) to prevent shell interpretation.

Step 5: Report

Issue #{id} registered
  Title: {title}
  Priority: {priority} | Type: {type}
  Status: backlog

Step 6: Done

Report the registered issue and stop immediately. Do not suggest next steps, do not offer to plan, do not continue.

This skill ends here. No exceptions.

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.
