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 | $0.00060 | $0.00823 |
| Opus 5 | $0.00030 | $0.00411 |
| Sonnet 5 | $0.00012 | $0.00165 |
| Haiku 4.5 | $0.00006 | $0.00082 |
Grade A, and why
rollback scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Comprehensive rollback system with multiple methods and automatic USER content preservation.
Rollback
This skill provides safe rollback operations with comprehensive validation and USER section preservation.
Usage
bunx forge rollback
Interactive menu with 6 options:
- Rollback last commit - Quick undo of most recent change
- Rollback specific commit - Target any commit by hash
- Rollback merged PR - Revert an entire PR merge
- Rollback specific files - Restore only certain files
- Rollback entire branch - Revert multiple commits
- Preview rollback - Dry run mode (shows changes without executing)
How It Works
Safety Features
1. Working Directory Check
- Requires clean working directory (no uncommitted changes)
- Prevents accidental data loss
- Prompts to commit or stash changes first
2. Input Validation
- Commit hashes: Must match
/^[0-9a-f]{4,40}$/ior be 'HEAD' - File paths: Validated to be within project (prevents path traversal)
- Methods: Whitelisted to 'commit', 'pr', 'partial', 'branch'
- Shell metacharacters: Rejected (
;,|,&,$,`,(,),<,>,\n,\r)
3. USER Section Preservation
- Automatically extracts USER sections before rollback
- Restores USER sections after rollback
- Preserves custom commands in
.claude/commands/custom/ - Amends rollback commit to include restored content
4. Dry Run Mode
- Preview affected files without executing
- Shows what would change
- No git operations performed
5. Non-Destructive
- Uses
git revert(creates new commit) - Never uses
git reset --hard(destructive) - Preserves full git history
- Can be undone with another rollback
USER Section Preservation
What Gets Preserved:
<!-- USER:START -->
Your custom content here
<!-- USER:END -->
<!-- USER:START:custom-name -->
Named USER section
<!-- USER:END:custom-name -->
Process:
- Extract all USER sections from AGENTS.md, CLAUDE.md, etc.
- Backup custom commands from
.claude/commands/custom/ - Execute rollback operation
- Restore USER sections to current file content
- Restore custom command files
- Amend rollback commit to include restored content
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

rollback is a skill published in the GitHub repository harshanandak/forge (4 stars, last pushed 3d ago), licensed MIT. It adds 60 tokens to every session and 823 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.
