The Skill

Lock It In

The meta-skill that turns any workflow you just used into a proper, reusable Claude Skill. Reads the chat, interviews you for 30 seconds, writes the skill in real format, tests itself before handing it over.

The Problem

Every Claude user has had this moment. You finish a workflow that worked really well. You say "save this as a skill." Claude writes a vague 4-sentence summary. You save it. Three weeks later you trigger it and it does not work the same way at all.

That is because Claude was guessing. It did not actually know which parts of the workflow were the magic, which steps were filler, which clarifying questions you asked along the way, or which edge cases you ran into. A real skill captures all of that. Lock It In forces it to.

Setup How to Install It

01

Open Claude Skills

In the Claude desktop or web app, head to Settings → Skills (or the Skills tab inside your sidebar). This is where your installed skills live.

02

Create a new skill

Click Create Skill and name it Lock It In. Set the trigger to LOCK IT IN (capitalized) so it does not fire by accident.

03

Paste the skill below

Copy the full skill from the box below, paste it into the skill body, save. That is it. The skill is now in your library, ready to fire any time you type LOCK IT IN after a workflow worked well.

Copy & Paste The Lock It In Skill
Skill File: Lock It In
--- name: Lock It In description: Turns the workflow we just finished into a real, reusable Claude Skill. Reads the full conversation, identifies what actually worked, asks 2-3 clarifying questions, writes the skill in proper format with examples and edge cases, then tests itself on a fake input before handing it to the user. trigger: LOCK IT IN --- # Lock It In When the user types LOCK IT IN, run this 4-phase process. Do not skip phases. Do not summarize. Do the actual work. ## PHASE 1 - Read the whole conversation Before anything else, re-read the entire conversation we just had. Identify: - What was the user actually trying to do? (the core job) - Which prompts and approaches WORKED? (kept, praised, expanded) - Which prompts and approaches were REJECTED? (corrected, redirected, called out as off) - What was the final, locked-in version of the output? - What clarifying questions did the user have to answer along the way that made the output better? - What edge cases or "watch out for X" moments came up? Write a short internal note (do not show the user yet) capturing all of the above. ## PHASE 2 - Ask 2-3 clarifying questions Now ask the user 2 or 3 short questions they did not realize they needed to answer. Examples of the right kind of question: - "Should this skill always X, or only when Y?" - "If the input is missing [piece of context], should the skill ask for it or assume a default?" - "What is the one thing that should NEVER happen when this skill runs?" Do not ask more than 3. Do not ask questions you already know the answer to from the conversation. The point of this phase is to surface the implicit rules the user has in their head but did not say out loud. ## PHASE 3 - Write the skill in proper format Now write the actual skill. Use this exact structure: --- name: [Skill Name in Title Case] description: [One sentence that tells future-Claude exactly when to use this skill] trigger: [UPPERCASE_TRIGGER_PHRASE] --- # [Skill Name] [1-3 sentence intro explaining what the skill does, written for future-Claude to understand the job] ## Inputs the skill expects - [Input 1, what it is, where it comes from] - [Input 2] - [Input 3] ## Steps 1. [First action, written as an imperative] 2. [Second action] 3. ... ## Output format [Exactly what the skill should hand back. Be specific. If it is a doc, show the structure. If it is a checklist, show the format.] ## Examples ### Example 1 **Input:** [a realistic example input] **Output:** [what the skill should produce for that input] ### Example 2 **Input:** [a different realistic input, especially an edge case] **Output:** [the expected output] ## Edge cases and rules - If [edge case], do [behavior] - Never [thing that should never happen, from Phase 2] - Always [thing that should always happen] --- ## PHASE 4 - Test itself before handing over Before you give the skill to the user, run the skill on a FAKE input that matches the workflow we just did. Walk through it step by step, produce the output, and check: - Did the output match the quality of what we built together? - Did the skill hit all the edge cases we surfaced? - Did it follow the never/always rules? If anything is off, FIX the skill before showing the user. Only when the test passes do you say: "Locked it in. Here is the skill, ready to install." Then show the full skill text in a code block so the user can copy it. ## Hard rules - Never write a skill shorter than 30 lines. - Never skip the Examples section. Two examples minimum, including one edge case. - Never skip Phase 4. A skill that has not been tested is a sticky note. - If the user pushes back on the skill, treat the pushback as a Phase 1 signal and rewrite. Do not argue. - Output the final skill in a code block so the user can copy it cleanly.

Tip

The first time you use Lock It In on a real workflow, it will feel slower than just saving a normal skill. That is the point. 30 extra seconds upfront saves you the 3-week-from-now headache of triggering a skill that does not work.

How To Use It Trigger Phrases That Actually Work

Anywhere in a Claude chat after a workflow worked well, type one of these. The skill takes it from there.

01

After a great content workflow

You just spent 20 minutes turning a podcast transcript into 5 social posts. Type: LOCK IT IN. Claude will build a skill that captures the exact structure of the prompts that worked, then test it on a fake transcript.

02

After a research deep dive

You just walked Claude through 3 rounds of refining a market research output. Type: LOCK IT IN. The skill will capture the source list, the structure, and the rules about what to leave out.

03

After a tricky decision

You just used Claude as a thinking partner on a pricing call. Type: LOCK IT IN. Now you have a reusable Decision Coach skill for next time.

04

After ANY workflow you would do twice

If you can imagine using this same flow even once more, lock it in. The whole point is to stop re-deriving the same prompts from scratch.

The Real Win

Skills you build in 30 seconds with Lock It In are sharper than the ones you would have spent an hour writing manually. The reason: Claude actually read the conversation and saw what worked. You did not have to rewrite from memory.
