chronos-protocol: Instructions file for Codex

AGENTS.md

chronos-protocol AGENTS.md is an instructions file for Codex, OpenCode from n0zer0d4y/chronos-protocol. It costs 353 tokens per session, scanned A, original, MIT.

A set of instructions for using Chronos Protocol, an activity-logging system for coding work. It requires each task to be started, linked to a task list, monitored when needed, and closed with recorded results.

In plain words
What is it for?
Logging debugging and feature work, updating task lists with activity IDs, checking elapsed time on long tasks, and recording completed results and notes.
Why use it?
It keeps a record of what work was done, which task it belonged to, how long it took, and how it ended.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Cursor.

This is n0zer0d4y/chronos-protocol's own configuration. It tells Codex and OpenCode how to work on chronos-protocol itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything chronos-protocol configures →

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

chronos-protocol AGENTS.md 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 2mo 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.

What it actually says

Integration Note: You may integrate these rules with your existing Cursor Rules. Customize the *_TASK_LIST.md filename pattern to match your project's naming convention.


Activity Logging Protocol

ALWAYS use Chronos Protocol's activity logging system for all coding tasks:

  1. Start Every Task: Call start_activity_log at the beginning of each coding task

    • Use appropriate activityType (debugging, feature-implementation, etc.)
    • Use matching task_scope from predefined options
    • Capture the returned activityId
  2. Track Task Progress: Input activityId into your task_list.md ActivityId column immediately after starting

  3. Complete Tasks Religiously: Call end_activity_log when finished

    • Include result and detailed notes for future reference
    • Update task status to "completed" in the active *_TASK_LIST.md
    • Record actual duration in ActualDuration column
  4. Monitor Ongoing Work: Use get_elapsed_time(activityId) to check progress on long-running tasks

Example Workflow:

# 1. Start activity and capture ID
activity_id = start_activity_log(
    activityType="debugging",
    task_scope="feature-implementation",
    description="Fix authentication module login flow"
)

# 2. Immediately update *_TASK_LIST.md with activityId
# 3. Work on the task...
# 4. Complete with results
end_activity_log(
    activity_id,
    result="Authentication module completed successfully"
)

Critical: Never skip activity logging. Every coding task must be tracked for traceability and performance analysis.

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.
