sync

sync is a skill for Claude Code from Jakeintech/waybill. It costs 129 tokens per session (2,532 once invoked), scanned A, original, MIT.

A skill for reconciling a work ledger with a task tracker and a Git host such as GitHub. It imports the user's own assigned issues and authored pull requests, then prepares a confirmed update.

In plain words
What is it for?
Importing recent tickets, pull requests, and project history; comparing them with ledger entries; and applying a planned synchronization after confirmation.
Why use it?
It helps recover a reliable record of work from project systems instead of maintaining the ledger by hand. It also limits the process to the user's own work.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

sync 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 1mo 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 — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sync

Pull the objective backbone — issues and merged PRs — from the user's tracker and git host, and reconcile it with the ledger. The reconciliation itself is deterministic: a CLI or MCP tool fetches raw JSON, the engine normalizes and diffs it, you present the plan, one confirmation applies it. Prefer CLIs (acli, gh) over MCP tools for the fetch: the same facts arrive with scoped fields in a fraction of the payload, saved to files instead of flowing through context.

Invoke the engine as "${CLAUDE_PLUGIN_ROOT}/bin/waybill" <command>.

Scope rule (non-negotiable)

Query only the current user's own items: issues assigned to them, PRs authored by them, in the projects/repos listed in config.json. Never fetch, store, or summarize individual colleagues' issues, PRs, or statistics, even on request — explain briefly per skills/ledger/references/methodology.md §6 and continue with the user's own data.

Procedure

  1. Read config.json for project_keys, repos, default_branch, and last_sync, and identity.json for the identity map. If last_sync is null, default the window to the last 90 days and say so. If identity.json lacks jira_account_id and the Atlassian MCP is connected, fetch the current user's accountId once and write it back — future queries stay scoped to it. (The acli path needs no accountId: currentUser() in the JQL scopes the fetch at the source.)

  2. Tracker — Jira. Two fetch paths; prefer the CLI when it is authenticated (acli jira auth status exits 0 — waybill status also reports this):

    acli (Atlassian CLI) — preferred. Two steps keep the payload minimal: search returns only keys, then each item is fetched with exactly the fields sync needs (search's flattened JSON cannot carry custom fields; view is REST-shaped and can):

    acli jira workitem search --json --limit 200 --fields key \
      --jql 'assignee = currentUser() AND project IN (<keys>) AND updated >= "<date>"' \
      > /tmp/waybill-keys.json
    # .issues? (with ?) also handles a bare-array payload without erroring:
    jq -r '(.issues? // .) | .[].key' /tmp/waybill-keys.json | while read -r KEY; do
      acli jira workitem view "$KEY" --json --fields \
        "summary,status,resolutiondate,created,updated,issuetype,parent,assignee,customfield_10016,customfield_10026,customfield_10002,customfield_10020,customfield_10010,customfield_10014,customfield_10011"
    done | jq -s '.' > /tmp/waybill-items.json

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.
