Atlas is a source-control system for coding agents that links each commit to the agent session, prompts, tool calls, and file changes that produced it. It is for developers who run multiple agents, switch between them, and need their work, decisions, and project knowledge tracked together. The catalogue includes a skill for working with Atlas.
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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 28 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00019 | $0.01166 |
| Opus 5 | $0.00010 | $0.00583 |
| Sonnet 5 | $0.00004 | $0.00233 |
| Haiku 4.5 | $0.00002 | $0.00117 |
Grade A, and why
atlas-self-configure 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 7d 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Atlas self-configure
Atlas's user-facing preferences live in one human-editable file,
config.toml. This skill is how you (an agent) read and change it safely —
without touching anything else Atlas persists.
Where the file lives
~/.config/atlas/config.toml
The same path on every platform. If $XDG_CONFIG_HOME is set to an absolute
path, it's $XDG_CONFIG_HOME/atlas/config.toml instead — check that variable
before assuming.
Editing that file is the supported mechanism, and the only one available to you: Atlas's config commands are IPC endpoints reachable from its own UI, not agent tools. Atlas watches the file and validates every change you make (see step 6 below), so a direct edit is a first-class way in — not a workaround.
If the file does not exist yet, Atlas hasn't created it (a fresh install before first launch, or the user deleted it). Do not create one speculatively — report that to the user instead of guessing at defaults.
The schema is in the file
Atlas writes a comment above every key: what it does, its default, and any constraint on its value — a numeric range, an exact set of allowed strings, "must not be empty". Read those comments and follow them. They are generated from the same table Atlas validates against, so they cannot drift from what it will actually accept.
Do not work from a schema you remember, or from one you saw in another project. The file in front of you is authoritative, and it is the only thing guaranteed to match the Atlas build the user is running.
Two things the comments won't spell out:
- A key that isn't there. Some settings mean "unset" by being absent —
TOML has no null. The comment for such a key sits above whichever key
follows it, so read the whole
[settings]block, not just the lines with values on them. To clear one of these, delete its line; never write an empty string. - A key Atlas doesn't recognize. It's preserved untouched and reported to the user as a diagnostic. Never delete a key you don't recognize.
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.

atlas-self-configure is a skill published in the GitHub repository pacifio/atlas (3,294 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 1,166 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.
