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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00024 | $0.00661 |
| Opus 5 | $0.00012 | $0.00331 |
| Sonnet 5 | $0.00005 | $0.00132 |
| Haiku 4.5 | $0.00002 | $0.00066 |
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.
How it starts
The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
- Tag Worthiness: MUST verify candidate tags against the Evaluation Matrix in REFERENCE.md. Reject low-savings or one-off tags.
- Syntax Format:
- MUST use
!<TAG><ARG>(2–3 uppercase letters, e.g.,!SP<N>,!PU [Text],!PA). - Tag handling MUST be case-insensitive (
!sp2matches!SP2).
- MUST use
- 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.
- DTTC section MUST always be placed at the very bottom (EOF) of target
- Approval Gate: NEVER modify target
SKILL.mdbefore 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
- Audit Friction: Identify typing volume, rigid thresholds, or missing mid-flight controls in target
SKILL.md. If none, exit. - Design Tags: Categorize into Start-time (
!TAG<ARG>) vs Mid-flight (!TAG [Text]). See REFERENCE.md. - Present Plan: Output proposed DTTC specification for user alignment.
- Append & Distribute: Upon approval, append template to EOF of target
SKILL.mdand runagents distribute.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

write-skill-dttc is a skill published in the GitHub repository loerei/chronicle-mcp (0 stars, last pushed 3d ago), licensed MIT. It adds 24 tokens to every session and 661 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
