clist: Skill for Claude Code

.agents/skills/add-management-command/SKILL.md

add-management-command is a skill for Claude Code, Codex from aropan/clist. It costs 42 tokens per session (757 once invoked), scanned A, original, Apache-2.0.

A guide for adding or fixing batch jobs in a Django web application. These jobs run commands that process many records, often on a schedule or through background workers.

In plain words
What is it for?
Use it when creating a command under the specified Django folder, adding command-line options, filtering resources by host, tracking failures, or connecting the command to cron and Healthchecks.
Why use it?
It helps keep new commands consistent with the application's existing structure, logging, error monitoring, and resource filtering. It also reduces the chance of scheduled jobs failing without being noticed.

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 →

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-management-command 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add or change a management command

Read two nearby commands with similar behavior before editing. For batch resource updates, set_account_rank.py and set_country_fields.py show the current conventions; anonymize_accounts.py shows a command with an explicit dry-run option. A command does not need a cron entry or EventLog merely because other commands use them.

Command behavior

  • Use Django's BaseCommand, add_arguments, and handle. Match the surrounding command's option names and logging style.
  • Resource.get(values, queryset=...) resolves host, short host, or ID and rejects unmatched values. Use Resource.available_for_update_objects when the operation should target only update-eligible resources.
  • AttrDict(options) and @print_sql_decorator(count_only=True) are optional project conventions. Log selected arguments when useful, but do not log raw options if they may contain credentials or personal data.
  • Use save(update_fields=[...]) when only known fields changed, so concurrent updates to unrelated fields are preserved. Choose bulk writes only when the command's behavior and database load justify them.
  • A --dryrun option is useful for consequential writes only if every write path actually honors it. Do not describe --verbose or a partial skip flag as a dry run.

EventLog

Choose the helper that matches the command. See src/logify/utils.py and src/logify/live.py:

  • failed_on_exception(event_log) marks failure and re-raises; mark completion yourself on success.
  • logging_event(**kwargs) creates one event and completes it on success.
  • stream_event_log(event_log, logger) also streams progress and completes an in-progress event on success.

A per-resource event is useful when individual failures need to be visible. A simpler command may only need normal logging. Check status transitions against EventStatus before adding a new pattern.

Cron and Healthchecks

If the command needs scheduling, add it to config/cron through src/run-manage.bash. Existing monitored entries use this shape:

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.
