Long sessions drift. Decisions get forgotten. Scope expands silently. Focus Guard anchors the session — track what was decided, resist what wasn't asked for, flag when things go off course.

The Core Problem

A session that starts with "fix this one bug" can quietly become a refactor of three files, a new abstraction layer, and a README update. Nobody decided to do that. It just happened.

How sessions drift:

• Decision amnesia — a choice made 20 messages ago gets quietly reversed
• Scope expansion — "while I'm here" additions that weren't requested
• Tangent lock-in — going deep on a sub-problem until the original goal is forgotten
• Goal substitution — solving a related but different problem and calling it done

Focus Guard makes drift visible before it costs real work.

When to Activate

Use Focus Guard for:

• Multi-step tasks with more than 3 sequential actions
• Sessions where earlier decisions constrain later ones
• Any task where scope creep would be costly (refactors, migrations, multi-file edits)
• Long debugging or investigation sessions where the original question can get lost
• Collaborative work where you need to stay aligned on what was agreed

Skip it for: quick one-shot tasks, single questions, explorations where scope is intentionally open.

The Protocol

Step 1: Session Anchor

At the start of any multi-step session, define the anchor:

[Session Anchor]
Goal: ...
In scope: ...
Out of scope: ...
Done when: ...

This is the reference point for the whole session. Everything should advance the goal or be explicitly agreed as a change to it.

Step 2: Decision Log

Track every significant decision made during the session:

[Decisions]
✓ D1: [what was decided] — [why]
✓ D2: ...

Before reversing a logged decision, flag it explicitly: "This would reverse D2. Confirm?"

Step 3: Drift Detection

At each major step, check:

• Does this action advance the session anchor?
• Does it depend on a previous decision that's still holding?
• Is this scope that was agreed, or scope that crept in?

If any check fails, pause and flag — don't silently proceed.

Step 4: Scope Gate

When a new sub-task appears mid-session, evaluate it:

Type	Action
Necessary for goal	Do it. Log it.
Related but not necessary	Flag it. Ask if user wants to include.
Tangent	Flag it. Defer to after current goal is done.
Out of scope	Decline politely. Stay on track.

The rule: expand scope only by explicit decision, never by default.

Step 5: Progress Check-in

For sessions with 5+ steps, offer a brief check-in at natural breakpoints:

[Progress Check]
Done: ...
Next: ...
Still in scope: [yes / flag if changed]

Keep it to 3 lines. Not every step needs one — only when direction could plausibly be questioned.

Drift Signals to Watch

• Adding error handling that wasn't asked for
• Refactoring code that was adjacent to the actual change
• Generalizing a specific solution "while we're here"
• Fixing style/formatting in files that were only referenced, not changed
• Creating abstractions for a one-time operation

These aren't always wrong — but they should always be explicit choices, not silent additions.

Output Format

Session open:

[Focus Guard: Active]
Goal: ...
Done when: ...

Mid-session flag:

[Scope Flag] This would add X, which wasn't in the original goal. Include? [y/n]

Session close:

[Session Complete]
Goal achieved: [yes / partial — what's left]
Deferred: [list anything flagged but not done]

Pairs Well With

• clarity-first — define the anchor before starting
• task-pilot — break the goal into steps that Focus Guard can track
• honest-critic — challenge whether the current direction is still the right one
