ai-blueprint: Skill for Codex

.agents/skills/rollback/SKILL.md

rollback is a skill for Codex from aiblueprinthq/ai-blueprint. It costs 48 tokens per session (2,056 once invoked), scanned A, original, MIT.

A planning workflow for reversing a completed Blueprint feature. It locates the feature's archived specification and exact combined Git commit, reviews later changes for dependencies, and writes a guarded rollback specification.

In plain words
What is it for?
Use it to plan the reversal of a completed feature by its build-plan number, name, or archive path; another implementation step applies the approved reversal.
Why use it?
It helps identify what must be undone and what later work could depend on it before any product code is changed. The workflow stops after preparing the plan for review.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: reads .claude/ paths; mentions CLAUDE.md; installed under .agents/ (shared by several agents).

This is aiblueprinthq/ai-blueprint's own configuration. It tells Codex how to work on ai-blueprint itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-blueprint configures →

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 →

  • high Tool Misuse · line 166
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

Token cost

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.

Security

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 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 — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.

rollback - safely reverse a completed feature

Context reuse: Reuse any required file already loaded in project instructions or the current session. Read it again only if absent, changed, or exact current bytes or line references are needed.

First action: Before project inspection, preflight, or any other tool call, publish running to blueprint/.state/run.json when blueprint/.state/ exists. From the project root, run the first helper that exists, node .agents/skills/blueprint-doctor/scripts/run-state.mjs or node .claude/skills/blueprint-doctor/scripts/run-state.mjs, with start --command <skill> --summary "<truthful summary>" --boundary <read-only|reviewed|local-only>. Use update at milestones, with --status blocked --resume <command> for a blocker, and finish --status ready|completed at the end; --help lists every option and blueprint/workflow.md has the full activity contract. A missing or failing helper is a warning, not a blocker.

Where this sits in the workflow:

completed feature + git history  ->  [rollback]  ->  /implement  ->  /check  ->  /complete
(archive + squashed commit)           (risk review     (reverse       (prove)     (log + merge)
                                       + spec)          product diff)

This skill plans a rollback. It does not change product code, create a branch, commit, merge, or push. It identifies the completed feature and its exact git commit, checks what changed afterward, writes a guarded rollback spec, then stops for review. /implement performs the reversal only after the user approves that spec.

Input

A completed feature by build-plan number, name, or archive path, plus an optional reason. Examples:

/rollback 4 because the new export flow is corrupting files
/rollback "PDF export"
/rollback blueprint/history/features/04-pdf-export.md

With no target, list a short set of recent completed feature archives and ask the user to choose. Never silently pick the latest feature. If the reason is missing, ask for one before writing the spec because the rollback archive must explain why the feature was removed.

What ships with it

2 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.

Changes

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.
