chronicle-mcp: Skill for Claude Code

.agents/skills/write-skill-dttc/SKILL.md

write-skill-dttc is a skill for Claude Code, Codex from loerei/chronicle-mcp. It costs 24 tokens per session (661 once invoked), scanned A, original, MIT.

A guide for adding standardized tags and domain terms to skills, so people can trigger parts of a workflow with short commands.

In plain words
What is it for?
Use it to review human input steps, define useful tags, and add them to the end of a skill file.
Why use it?
It helps reduce repeated clarification and other points where a person must guide the agent manually.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is loerei/chronicle-mcp's own configuration. It tells Claude Code and Codex how to work on chronicle-mcp 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 chronicle-mcp 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

write-skill-dttc 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 4d 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.

Write Skill DTTC

Audit human-in-the-loop (HITL) interaction points in skill workflows and append standardized Domain Terms and Tag Commands (DTTC) to the bottom of target SKILL.md.

Directives

  1. Tag Worthiness: MUST verify candidate tags against the Evaluation Matrix in REFERENCE.md. Reject low-savings or one-off tags.
  2. Syntax Format:
    • MUST use !<TAG><ARG> (2–3 uppercase letters, e.g., !SP<N>, !PU [Text], !PA).
    • Tag handling MUST be case-insensitive (!sp2 matches !SP2).
  3. Placement & Idempotency:
    • DTTC section MUST always be placed at the very bottom (EOF) of target SKILL.md.
    • If a DTTC section already exists, merge new tags and reposition the section to EOF.
  4. Approval Gate: NEVER modify target SKILL.md before explicit user approval.

Template (SKILL.md Bottom Section)

Append this exact structure to the bottom of target SKILL.md:

## Domain Terms and Tag Commands

The `<skill-name>` supports modifier tags and domain terminology to control execution flow:

- **`<DOMAIN_TERM>`**: [Concise definition of the shared concept].
- **`!<TAG><ARG>` (<Full Name>)**: [Primary purpose].
  - **Syntax/Parameter**: `!<TAG><ARG>` (Default: `<default_value>`).
  - **Timing**: `[Start-time / Mid-flight]`.
  - **Agent Action**: [Explicit step-by-step action taken upon receiving tag].

Execution Steps

  1. Audit Friction: Identify typing volume, rigid thresholds, or missing mid-flight controls in target SKILL.md. If none, exit.
  2. Design Tags: Categorize into Start-time (!TAG<ARG>) vs Mid-flight (!TAG [Text]). See REFERENCE.md.
  3. Present Plan: Output proposed DTTC specification for user alignment.
  4. Append & Distribute: Upon approval, append template to EOF of target SKILL.md and run agents distribute.

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.
