billing-narrative

billing-narrative is a skill for Claude Code from protomated/protomated-plugins-official. It costs 76 tokens per session (1,265 once invoked), scanned A, original, Apache-2.0.

A time-entry writing aid that turns rough notes, email threads, or work descriptions into a clear description suitable for a law firm's billing system and suggests a time increment.

In plain words
What is it for?
Use it to describe tasks such as client calls, reviewing correspondence, or drafting a letter for systems such as Clio, MyCase, or PracticePanther. It produces a draft rather than entering anything automatically.
Why use it?
It removes the need to rewrite shorthand into consistent billing language after completing billable work. The attorney confirms that the description and time are accurate before billing.

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

billing-narrative 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 6d 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.

/billing-narrative — Billing Narrative & Time-Entry Drafting Skill

⚠️ AI-ASSISTED DRAFT — ATTORNEY REVIEW REQUIRED This output was generated by an AI assistant. The narrative and time increment are a starting point — the attorney must confirm accuracy, adjust the time, and approve before billing. This is not legal advice.

Draft a clean, billing-code-appropriate time narrative and suggest a time increment from your rough notes or a description of work performed. Attorney reviews and confirms before entering into the billing system.

This skill reads what you provide and outputs a draft. It does not write to any file or billing system without your confirmation.

Invocation

/billing-narrative [paste rough notes or describe the work]
/billing-narrative "called client re: depo scheduling, reviewed 3 emails from opp counsel, drafted response letter"

Workflow

Step 1 — Collect the raw input

Accept one of:

  • Pasted rough notes — attorney types or pastes what they did (informal, shorthand, incomplete is fine)
  • An email thread — attorney forwards or pastes a thread; skill drafts the narrative from the actions visible in the thread
  • A matter folder reference — use the Filesystem connector to read recent notes or a work log file from the specified matter folder
  • A verbal description — attorney describes the work in plain language

If the attorney provides an approximate time ("about 2 hours," "maybe 45 minutes"), record it as input. If no time is provided, ask.

Step 2 — Identify the billing context

Ask or infer from the input:

  • Matter name or client — for the narrative header
  • Work type — what category of legal work this represents:
    • Client communication
    • Document drafting / review
    • Legal research
    • Court appearance / hearing
    • Deposition
    • File review / case management
    • Administrative
  • Billing code (if the attorney uses a code system like UTBMS/task codes) — ask if not provided; leave a placeholder if unknown
