task-sync

task-sync is a skill for Claude Code from davistroy/claude-marketplace. It costs 169 tokens per session (5,040 once invoked), scanned A, original, MIT.

A local task and backlog manager built around a tasks.json file, with an automatically generated TASKS.md view. It can optionally reconcile local tasks with GitHub or Gitea issues.

In plain words
What is it for?
Use it to list, add, edit, complete, remove, and synchronize tasks, with explicit decisions for conflicts and public-repository changes.
Why use it?
It keeps task tracking local while making conflicts and changes visible before anything is pushed to an issue tracker.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; names the AskUserQuestion tool; mentions Claude Code.

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

task-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 3d 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 — 419 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Task Sync

Local-first task tracking backed by a canonical tasks.json (with a generated, read-only TASKS.md view) that optionally reconciles with GitHub or Gitea issues. All logic lives in the bundled task_sync Python tool — this skill's job is invocation, table rendering, and human-in-the-loop decisions (conflict resolution, confidentiality review, the public-repo push warning). The tool never auto-resolves a conflict and never pushes anything without an explicit plan the user has seen.

Setup

The tool is bundled at tools/task-sync/src. Resolve the plugin root the same way other bundled-tool skills do, then invoke every subcommand through python3 -m task_sync:

PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$(find ~ -path '*/plugins/personal-plugin' -type d 2>/dev/null | head -1)}"
TOOL_SRC="$PLUGIN_DIR/tools/task-sync/src"

PYTHONPATH="$TOOL_SRC" python3 -m task_sync status

tasks.json lives at the target repo's root by default (--tasks tasks.json, resolved relative to the working directory). Pass --tasks <path> for any other location.

Version-skew preflight

Run this once, before the first subcommand, and report the result if it warns:

python3 - "$PLUGIN_DIR" <<'PY'
import json, os, re, sys
served = re.search(r"/personal-plugin/(\d+\.\d+\.\d+)(?:/|$)", sys.argv[1])
served = served.group(1) if served else None
reg = os.path.expanduser("~/.claude/plugins/installed_plugins.json")
try:
    entries = json.load(open(reg))["plugins"]["personal-plugin@troys-plugins"]
    installed = entries[0]["version"]
except Exception:
    installed = None
if served and installed and served != installed:
    print(f"WARNING: this session is serving personal-plugin {served}; "
          f"{installed} is installed. Run /reload-plugins to pick it up "
          f"(a full restart also works). "
          f"Until then this skill body may be older than the bundled tool.")
else:
    print(f"version-skew: none ({served or 'unknown'})")
PY

Why this exists. A running Claude Code session serves the plugin version it resolved at start-up. claude plugin update writes installed_plugins.json and prints "Restart to apply changes", but it does not change what the current session is already serving. So a long-lived session can run the current bundled tool from repo source while reading a stale skill body — a current tool against an old contract, with no error anywhere. That is #232: a session served an 11.3.0 body whose plan-JSON key list predated orphans, so the orphan findings the tool emitted were never read.

Changes

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.
