ralphex is a command-line tool that runs coding agents through implementation plans, executing repository tasks autonomously in separate sessions. It is intended for developers who want long-running features implemented, validated, reviewed, and committed with less interactive supervision.
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 111 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 | $0.00074 | $0.04906 |
| Opus 5.5 | $0.00030 | $0.01962 |
| Sonnet 5.5 | $0.00015 | $0.00981 |
| Haiku 4.5 | $0.00007 | $0.00491 |
Grade A, and why
ralphex-adopt scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

ralphex-adopt - Convert Plans Into ralphex Format
SCOPE: Read a source plan in some other format and produce a new ralphex-format plan at docs/plans/YYYYMMDD-<slug>.md. The source is never modified. Existing target files are never silently overwritten.
Supported source shapes:
- OpenSpec change: directory containing
proposal.md,tasks.md, optionalspecs/**/spec.md - spec-kit spec: directory or file with spec/plan/tasks separation
- GitHub or GitLab issue: URL,
#N, orowner/repo#Nwith body that contains a task checklist - Generic task-list: any structured markdown/text with headings and bullet items
- Free-form markdown: prose brain dump with no fixed structure
This is a single-skill conversion: discover, classify, ask focused questions when in doubt, draft, review, write. Do not modify code, do not run tests, do not commit. Output is the new plan file only.
Step 0: Optional CLI Check
This check is informational only. Missing ralphex CLI must NOT break the flow — conversion does not require it. Do NOT block, exit, prompt the user, or wait for installation. Always continue to Step 1 regardless of the result.
which ralphex
If which ralphex returns non-zero, briefly mention that ralphex is needed to execute the converted plan later (not now), list install options once, and continue immediately:
- macOS (Homebrew):
brew install umputun/apps/ralphex - Linux (Debian/Ubuntu): download
.debfrom https://github.com/umputun/ralphex/releases - Linux (RHEL/Fedora): download
.rpmfrom https://github.com/umputun/ralphex/releases - Any platform with Go:
go install github.com/umputun/ralphex/cmd/ralphex@latest
If which ralphex succeeds, say nothing and proceed.
Step 1: Resolve Source From Argument Shape
Inspect $ARGUMENTS and pick exactly one source by shape, in this order:
- Full URL (starts with
http://orhttps://):- GitHub issue/PR URL → use
gh issue view <url> --json title,body,labels(orgh pr view) - GitLab issue/MR URL → use
glab issue view <url>(orglab mr view) - Other URL → fetch with
curl -fsSLonly if it points at a raw markdown file; otherwise AskUser to paste the body
- GitHub issue/PR URL → use
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.

ralphex-adopt is a skill published in the GitHub repository umputun/ralphex (1,504 stars, last pushed 3d ago), licensed MIT. It adds 74 tokens to every session and 4,906 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
