Transparent notes on how PasteLint’s deterministic revision engine changes.

Directness Without False Certainty

Why SecondDraft stopped treating qualified language as something to delete.

By Guy Teichman

The defect

A cleaner sentence can still become less accurate.

That was happening in SecondDraft’s Direct mode. Words such as may, probably, and I think were sometimes treated as hesitation and removed. The result sounded firmer—but it also said something different.

Direct now follows a narrower rule: simplify a supported request when it is safe, but preserve the original level of certainty, who is responsible, and whether the sentence offers a recommendation or states a requirement.

The old behavior

Four small edits were changing what the sentence meant.

Direct mode could change may to can and remove probably, I think, and It seems that. Each edit looked small. Each could make the revised sentence claim more than the original.

The problem was not that every cautious phrase deserved to stay. It was that the editor could not tell whether those words were empty padding or essential meaning.

Possibility versus capability

May and can are not interchangeable.

Concept Illustration · Does not execute PasteLint

Possibility is not capability

Original sentence

The event may be canceled if severe weather continues.

Possible revision

The event can be canceled if severe weather continues.

Decision

Do not apply this revision. Preserve may.

Why this decision was made

May describes an uncertain outcome here. Can may describe ability, authority, or permission, so the proposed substitution would change the claim.

Preserved
Possibility, the severe-weather condition, and the event remain intact.
Changed
No wording changes in this example.
Intentionally unchanged
The sentence remains unchanged because the proposed edit would convert possibility into capability.

Text summary: Original: The event may be canceled if severe weather continues. Possible revision: The event can be canceled if severe weather continues. Decision: do not apply the revision; preserve may because possibility is not capability.

Limitation: This illustration explains one editorial distinction and does not execute PasteLint.

Complete concept illustration available without interaction.

“The event may be canceled” describes an uncertain outcome. “The event can be canceled” can describe ability or permission. The sentences are close in length, but they do not make the same claim.

Probability versus certainty

Removing probably can overstate the evidence.

Source: The launch will probably be delayed if approval arrives after Tuesday.

Unsafe rewrite: The launch will be delayed if approval arrives after Tuesday.

Current Direct output: The launch will probably be delayed if approval arrives after Tuesday.

Removing probably does not merely make the sentence shorter. It turns a likely delay into a definite one.

Attributed judgment versus fact

“I think” can be part of the meaning.

Source: I think the revised menu is ready for review.

Unsafe rewrite: The revised menu is ready for review.

Current Direct output: I think the revised menu is ready for review.

In workplace writing, I think can show that a statement is someone’s assessment—not a verified fact. SecondDraft cannot check whether the menu is actually ready, so it should not write as though it has.

Negated possibility

Two small words can change the entire situation.

Source: The library may not approve the revised menu.

Unsafe rewrite: The library can not approve the revised menu.

Current Direct output: The library may not approve the revised menu.

“May not approve” means approval is uncertain. “Can not approve” suggests the library lacks the ability or authority to approve it. The difference changes what the reader believes is possible.

A supported request

What Direct mode can safely change.

Source: We were hoping you could confirm whether the library may not approve the menu.

Current Direct output: Please confirm whether the library may not approve the menu.

Here the extra request framing can go. The words inside the request cannot. The revision still asks about the library, the menu, and the possibility that approval may not happen.

The result is more direct without becoming more certain.

Direct mode may shorten a supported request while leaving the meaning inside it unchanged.

Recommendation strength

A suggestion is not a command.

Source: The main point is that we should review the dates before recording.

Current focused output: We should review the dates before recording.

The opening announcement can be removed, but we, should, and before recording still matter. Dropping should would turn a recommendation into an instruction. Dropping we would change who is responsible.

What changed

A safer editor sometimes leaves the sentence alone.

  • Direct no longer automatically changes may to can or removes probably, I think, and It seems that.
  • Supported requests keep words that express uncertainty, conditions, and responsibility.
  • The focused main-point edit keeps we should, while tested a.m. and p.m. forms remain intact during sentence cleanup.

Regression coverage

What SecondDraft now leaves intact.

Possibility
Remains possibility
Probability
Remains probability
Recommendation

Negation

Remain fixture-backed

Coverage also includes

  • Possibility, permission, likelihood, judgment, recommendations, requirements, conditions, and negation.
  • Quoted, technical, policy, IVR, contractual, and numeric language, plus protected dates and contact details.
  • Already-direct requests and unsupported constructions that should remain unchanged.

Engine principle

Sometimes the right edit is no edit.

If removing a cautious word would change what the writer claims, leaving the sentence alone is the more accurate choice.

Under the hood

Narrow rules, checked against specific examples.

SecondDraft runs in the browser and uses a limited set of tested rules. For supported requests, it checks the final text before returning an edit note. SD-CLARITY-002 applies only to those request openings. The tests cover specific examples; they do not give the editor a human understanding of every sentence.

Takeaway

Change the frame. Preserve the claim.

Compare a qualified statement with a supported request and review exactly what the engine changes.
