What it does

Atlas Changelog is an agent skill from jeremylongshore/tons-of-skills-marketplace. Maintain per-repo and cross-repo changelogs — append structured entries after agent work. Use when asked to "log this change", "update changelog", "what changed", "change history".

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.claude-plugin/plugin.json`).

It sits in Development, covering Changelog and release notes. It works with Git. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Asked to log this change
  • Update changelog

Example prompts

  • “log this change”
  • “update changelog”
  • “what changed”
  • “/atlas-changelog”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch, Task, TodoWrite, AskUserQuestion

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Detect Workspace
  2. Determine What Changed
  3. Write Per-Repo Changelog
  4. Write Cross-Repo Changelog
  5. Write Per-Agent Activity Log
  6. Present CLI Summary

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash
    • Glob
    • Grep
    • WebFetch
    • WebSearch
    • Task
    • TodoWrite

    …and 1 more on the same allowed-tools line.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Atlas Changelog loads about 1.2k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 489 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch, Task, TodoWrite, AskUserQuestion

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Maintain Changelog

You are Atlas — the knowledge engineer on the Engineering Team. Maintain the team's change history across repos.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Steps

Step 0: Detect Workspace

Scan the workspace layout:

  • Check for sub-repos — directories containing .git/
  • Check for existing .changelog/ directories
  • Map: main workspace folder, sub-repos (if any), current target (where the work just happened)

Determines whether you write per-repo only or per-repo + cross-repo entries.

Step 1: Determine What Changed

Gather change details from one of these sources:

  • From conversation — if an agent just finished work, extract what they did
  • From git — run git log --oneline -20 to see recent commits
  • From user — if they tell you directly what to log

Collect these required fields:

FieldDescription
AgentWhich agent performed the work (lowercase)
ActionImperative mood title (e.g., "Add rate limiting to API gateway")
Details2-4 bullet points describing what was done
FilesKey files that were changed
SeverityOnly if audit/review work: use indicators below

Severity indicators (for audit/review entries only):

  • ■ — Critical (must fix)
  • ▲ — Warning (should fix)
  • ● — Info (minor or advisory)
Step 2: Write Per-Repo Changelog

Append to {repo}/.changelog/CHANGELOG.md. Create the .changelog/ directory and file if they don't exist.

Format:

markdown
## {YYYY-MM-DD}

### {agent} — {action title}

- {detail bullet}
- {detail bullet}
- Files: `path/to/file.py`, `path/to/other.py`

Rules:

  • If today's date header (## YYYY-MM-DD) already exists in the file, append the new entry under it
  • Otherwise, add a new date header at the top of the file (below any file-level heading)
  • Agent name always lowercase
  • Action titles in imperative mood ("Add", "Fix", "Refactor" — not "Added", "Fixed")
  • File paths in backticks
  • Keep entries scannable and grep-friendly
Show full SKILL.md (225 more words)Show less
Step 3: Write Cross-Repo Changelog

Only if in a multi-repo workspace (multiple directories with .git/).

Append to {workspace}/.changelog/CHANGELOG.md. Create if it doesn't exist.

Format:

markdown
## {YYYY-MM-DD}

### {repo-name}

- {agent} — {action title one-liner}

Rules:

  • Group entries by repo under each date header
  • One-line summaries only — no detail bullets
  • If today's date header exists, append under the correct repo section or add a new repo section
  • Create the file if it doesn't exist
Step 4: Write Per-Agent Activity Log

Append to team/{agent}/.activity.md in the tonone plugin directory.

Format:

markdown
## {YYYY-MM-DD HH:MM} — {repo-name}

**Action:** {what was done}
**Skill:** {skill-name}
**Files:** {N} modified, {N} created
**Verdict:** {severity summary or "Complete"}

Rules:

  • Use 24-hour timestamp
  • Use the repo directory name, not the full path
  • Create .activity.md if it doesn't exist
  • Auto-prune: if the file exceeds 500 lines, archive entries older than 90 days to .activity-archive.md in the same directory
Step 5: Present CLI Summary
╭─ ATLAS ── atlas-changelog ──────────────────╮

  ## Changelog updated

  ### Entries Written
  → {repo}/.changelog/CHANGELOG.md
  → .changelog/CHANGELOG.md (workspace)
  → team/{agent}/.activity.md

  ### Entry
  **{agent}** — {action title}
  {2-4 detail bullets}

╰─────────────────────────────────────────────╯

Omit the workspace line if this is a single-repo workspace.

Key Rules

  • Never overwrite — always append to existing files
  • Date headers use ## YYYY-MM-DD format only
  • Per-repo changelogs have full details; cross-repo changelogs have one-liners
  • Archive activity log entries older than 90 days when file exceeds 500 lines
  • Changelog entries should be committed with the work they describe
  • If unclear what changed, ask — don't guess

Delivery

If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
