Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00068 | $0.02249 |
| Opus 5 | $0.00034 | $0.01125 |
| Sonnet 5 | $0.00014 | $0.00450 |
| Haiku 4.5 | $0.00007 | $0.00225 |
Grade A, and why
writing-modpack-devlog 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Overview
The modpack dev-log is the durable record of what the curator did to the modpack, in chronological order, with enough context for a future maintainer to understand why a change happened. This skill replaces the deleted templates/modpack/dev-log.md template by creating <project>/docs/dev-log.md at runtime, then appending entries as the modpack evolves.
When to Use
| Use this skill when... | Result |
|---|---|
| The user says "log this", "add to dev log", "record what I did", or "note this change" | Append a dated entry to the project dev-log. |
| A mod was added, removed, replaced, upgraded, downgraded, patched, or moved in load order | Record what changed and why. |
| A conflict-audit session finished | Summarize the finding and link evidence from xedit-conflict-audit or xedit-automation output. |
| A CTD, freeze, missing asset, bad facegen, navmesh issue, or broken quest was investigated | Preserve the investigation result, even if the fix is not final. |
| A modpack release was cut | Add the curator-facing note and cross-link to writing-modpack-changelog. |
| The user made a manual decision that future agents must not re-litigate | Record the decision, context, and evidence. |
When NOT to Use
| Do not use this skill when... | Use instead |
|---|---|
| The user is preparing public release notes for players | writing-modpack-changelog |
| The user asks for a one-off explanation without wanting a project record | Answer directly. |
| The project root is unknown and the user refuses to identify it | Stop after explaining what is missing. |
| The entry would expose private notes, credentials, or personal information | Ask for a sanitized version first. |
| The request is to inspect or edit plugin records | xedit-automation or xedit-conflict-audit first, then log the result. |
Rules
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.

writing-modpack-devlog is a skill published in the GitHub repository hashgraph-online/awesome-codex-plugins (859 stars, last pushed 5d ago), licensed Apache-2.0. It adds 68 tokens to every session and 2,249 once invoked, about $0.0003 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 2026-08-30.
