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 | $0.00055 | $0.01286 |
| Opus 5 | $0.00028 | $0.00643 |
| Sonnet 5 | $0.00011 | $0.00257 |
| Haiku 4.5 | $0.00006 | $0.00129 |
Grade A, and why
stepback 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stepback - Strategic Reassessment
Core principle: If you've tried 2+ fixes for the same class of problem, you're probably patching symptoms. Stop. Zoom out. Research the architecture.
When to Trigger
digraph stepback {
"Fix attempt failed?" [shape=diamond];
"Is this the 2nd+ attempt?" [shape=diamond];
"Same root system?" [shape=diamond];
"Keep debugging" [shape=box];
"STOP — Run /stepback" [shape=box, style=bold];
"Fix attempt failed?" -> "Is this the 2nd+ attempt?" [label="yes"];
"Fix attempt failed?" -> "Keep debugging" [label="no, first try"];
"Is this the 2nd+ attempt?" -> "Same root system?" [label="yes"];
"Is this the 2nd+ attempt?" -> "Keep debugging" [label="no"];
"Same root system?" -> "STOP — Run /stepback" [label="yes"];
"Same root system?" -> "Keep debugging" [label="different systems"];
}
Symptoms that demand /stepback:
- Same error returns after a "fix"
- Fix A reveals error B reveals error C (cascade)
- Locally it works, deployed it doesn't
- Multiple components broken by the same underlying cause
- Fixes feel like whack-a-mole
Proactive triggers (don't wait for failure):
- Touching deployment config, build pipeline, or infrastructure
- Changing middleware, routing, or auth at the platform level
- Modifying
next.config.js,vercel.json, Dockerfile, CI/CD
Execution
STEP 1 — Stop and Inventory
List every fix attempt so far in this session. For each:
- What symptom it addressed
- Whether it worked or revealed a new symptom
- What assumption it was based on
Present this to the user as a table:
| # | Fix | Symptom | Result | Assumption |
|---|-----|---------|--------|------------|
| 1 | Added route to middleware whitelist | 405 on webhook | Still 405 | Middleware was blocking |
| 2 | Replaced parseBody with manual HMAC | 500 crash | Still 500 | parseBody incompatible |
| 3 | ... | ... | ... | ... |
STEP 2 — Find the Common Thread
Ask: "What system do ALL of these symptoms share?"
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.

stepback is a skill published in the GitHub repository anombyte93/atlas-session-lifecycle (88 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 1,286 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.
