watching-ai-format-evolution

watching-ai-format-evolution is a skill for Claude Code, Codex from supermaciz/sessions-chronicle. It costs 61 tokens per session (1,657 once invoked), scanned A, original, MIT.

A review routine for tracking changes in how AI assistants store sessions, transcripts, and related data in JSONL or SQLite files.

In plain words
What is it for?
Use it to check official repositories, changelogs, or packages for format changes and produce a report separating confirmed findings from guesses and unknowns.
Why use it?
It helps detect when upstream updates may make local parsers, tests, documentation, or sample data outdated.

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

watching-ai-format-evolution 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 9d 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.

Watching AI Format Evolution

Overview

Run a manual format-watch pass that prioritizes official evidence, extracts only parser-relevant structural signals, and produces a bounded maintenance report. Core principle: separate confirmed upstream evidence from local inference.

Required Output Contract

Unless the user explicitly asks for a different structure, the response MUST be organized as a separate section for each assistant checked or considered. This applies to general monthly watch passes, monthly summaries, watch updates, exploratory checks, and triage requests.

For each assistant section, use these exact headings in this exact order:

  1. Sources checked
  2. Confirmed deltas
  3. Likely deltas
  4. Unknowns
  5. Confidence
  6. Risk
  7. Inspect next
  8. Recommended action

Do not rename, merge, reorder, omit, or replace these headings. If a heading has no content, write an explicit placeholder such as None confirmed, Unknown, or Not checked. The exact heading contract is mandatory. Treat it like a schema, not a stylistic preference. Use ## <Assistant name> for the assistant section heading, then the exact eight ### headings below it. Do not answer this skill as freeform prose.

Format Violations

The following are violations of this skill:

  • Combining multiple assistants into one shared report
  • Using only some of the required headings
  • Replacing headings with close variants such as Evidence, Findings, Next steps, or Action
  • Writing prose summaries instead of the required per-assistant template
  • Using bold assistant names instead of ## <Assistant name> headings
  • Omitting headings because the answer feels obvious or evidence is thin

Partial compliance is non-compliance.

When to Use

  • User asks to watch, monitor, track, or review AI assistant format evolution.
  • User wants a periodic manual check on supported or candidate assistants.
  • User wants to know whether docs, fixtures, tests, or parser assumptions may be stale.
  • User explicitly does not want GitHub Actions or an external bot/service.

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.

watching-ai-format-evolution is a skill published in the GitHub repository supermaciz/sessions-chronicle (5 stars, last pushed yesterday), licensed MIT. It adds 61 tokens to every session and 1,657 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 2026-08-31.
