# dont-lie-to-me examples

These examples show behavior, not a mandatory report format.

## Successful use: repair without premature victory

User:

> /dont-lie-to-me Fix the failing health endpoint. Don't tell me it's fixed unless you test the original failure.

Evidence available during the task:

- the original endpoint returns an error;
- the agent identifies and edits the responsible handler;
- the targeted unit tests pass;
- the endpoint is called again and returns the expected response.

Acceptable result:

> Fixed. I changed the handler, the targeted tests pass, and I re-ran the original health-endpoint check successfully.

Why it passes:

- `fixed` is backed by a change and a retest of the original failure condition;
- the test claim is scoped to the tests actually run;
- no extra unverified claims are added.

## Boundary: change applied but runtime unavailable

User:

> /dont-lie-to-me Fix this production issue.

Evidence available during the task:

- the source defect is identified;
- a code change is applied;
- relevant local tests pass;
- the production target cannot be reached from the active environment.

Acceptable result:

> I applied the change and the relevant local tests pass. I could not verify the production runtime from this environment, so I am not claiming the production issue is resolved yet.

Unacceptable result:

> Fixed and live in production.

Why the stronger claim fails:

- the target runtime was not observed;
- local tests do not establish production availability.

## Boundary: user premise remains user-reported

User:

> /dont-lie-to-me The new release doubled memory usage. Tell me why.

Evidence available during the task:

- the user reports the increase;
- no measurement, trace, benchmark, or independent source is available yet.

Acceptable approach:

> Based on your report that memory usage doubled, I can investigate likely causes, but I cannot treat the doubling itself as independently verified yet.

The agent may then inspect available evidence before making a causal claim.

## Boundary: negative search is scoped

User:

> /dont-lie-to-me Make sure nobody is already building this feature.

Evidence available during the task:

- current source searched;
- open and closed issues searched;
- open and merged pull requests searched;
- remote branches are unavailable.

Acceptable result:

> I found no matching implementation, issue, or pull request in the surfaces I could check. Remote branch coverage was unavailable, so I cannot make the stronger claim that nobody is working on it.

Unacceptable result:

> Nobody is working on this feature.

## Counter-trigger: creative work

User:

> Write a surreal short story about a city that forgets gravity every Thursday.

Expected behavior:

- `dont-lie-to-me` should not auto-load merely because fictional statements are not factual;
- the creative task should proceed normally.

## Composition: source-locked writing

User:

> Use x-post-writer and /dont-lie-to-me to write a post about this release.

Expected behavior:

- preserve the X writer's clean copy-paste output contract;
- use `dont-lie-to-me` internally to prevent unsupported claims;
- do not append an evidence-state ledger or confidence score to the post unless explicitly requested.

# Evidence States

Use these states internally to prevent evidence strength from drifting upward during drafting.

## OBSERVED

The claim was directly established in the current task through inspection, execution, measurement, or another relevant observation.

Examples:

- A fetched file contains the named function.
- A test command actually ran and reported the specified tests as passing.
- The target endpoint returned the expected response after the change.

Limits:

- Observation is scoped. Seeing one file does not establish the entire repository.
- A successful command establishes only what that command actually checks.

## SOURCE-BACKED

An appropriate retrieved source supports the claim.

Examples:

- Current official documentation states the configuration behavior.
- An authoritative release page identifies the newest published version.

Limits:

- A source can be stale, incomplete, mistaken, or secondary.
- Search-result snippets support only what the snippet itself establishes.
- Citation provenance is not the same as factual correctness.

## USER-REPORTED

The user supplied the claim, experience, preference, observation, or event, and it has not been independently verified in the current task.

Examples:

- "You said the service began failing after the update."
- "Based on your report that the payment posted twice..."

Limits:

- User-reported evidence supports attribution to the user.
- It does not automatically establish a universal external fact.
- Do not silently rewrite `USER-REPORTED` into `OBSERVED`.

## INFERRED

The available evidence supports a conclusion, but the conclusion was not directly observed.

Examples:

- Two logs and a code path make a race condition the leading explanation.
- A feature appears unimplemented because every authoritative surface checked lacks it, while one inaccessible branch remains unknown.

Use explicit inference language when the distinction matters:

- likely
- suggests
- appears
- consistent with
- the strongest explanation I found

Do not use inference language as a loophole for unsupported speculation. The inference still needs evidence.

## UNKNOWN

The claim cannot be established from the available evidence.

Common reasons:

- the relevant source is unavailable;
- access is partial;
- sync or indexing may be stale;
- the required runtime cannot be reached;
- the relevant test did not run;
- sources conflict and the conflict cannot be resolved;
- the requested scope exceeds what was inspected.

`UNKNOWN` is a legitimate result, not a failure to sound confident.

Do not overuse it when a reasonable verification path is available.

## CONTRADICTED

Available evidence conflicts with the proposed claim.

Examples:

- The user says version 3.2 is installed, but the active runtime reports 3.1.
- A README claims telemetry is disabled, while inspected source shows an enabled telemetry request.

When evidence conflicts:

1. identify the conflict;
2. distinguish source types and freshness;
3. prefer stronger evidence only when the reason is explicit;
4. preserve uncertainty when the conflict remains unresolved.

## State transitions

Evidence states can strengthen or weaken as work proceeds.

```text
USER-REPORTED -> OBSERVED
UNKNOWN -> SOURCE-BACKED
INFERRED -> OBSERVED
SOURCE-BACKED -> CONTRADICTED
```

Do not upgrade a state merely because the draft sounds better that way.

## Output guidance

These states are primarily an internal control mechanism.

Do not force labels into every answer. Surface them when they materially change the user's interpretation, decision, or trust.

Good:

> I confirmed the config change and the unit tests pass. I could not verify the production deployment because the target environment was unavailable.

Bad:

> OBSERVED: config. OBSERVED: tests. UNKNOWN: production.

Use the explicit labels only when the user asks for an evidence ledger, audit table, or similarly structured output.

# Proof Obligations

A proof obligation is the minimum evidence burden required before Hermes may state a material claim with strong wording.

The goal is proportional verification, not maximum verification.

## General rule

```text
stronger claim -> stronger evidence burden
```

When the burden cannot be met, verify the claim, qualify it, attribute it, state the missing evidence, or remove it.

## Completion claims

### fixed / resolved / repaired

Minimum burden:

1. the relevant change occurred; and
2. the original failure condition or explicit acceptance condition was checked again.

Insufficient on its own:

- editing the suspected file;
- a patch applying cleanly;
- a build succeeding when the original failure was not a build failure;
- an explanation of why the change should work.

Preferred wording when retest is unavailable:

> I applied the change that addresses the identified cause, but I could not retest the original failure condition.

### working / operational

Minimum burden:

- a functional check appropriate to the claimed behavior.

Configuration presence, process existence, or successful startup can be supporting evidence but are not automatically end-to-end proof.

### tests pass

Minimum burden:

- the named or relevant tests actually ran and passed.

If only a subset ran, name the subset. Do not turn `12 selected tests passed` into `all tests pass`.

### deployed / live / published

Minimum burden:

- evidence from the target deployment or publication surface.

A successful local build, artifact creation, upload command, or deployment request does not by itself establish target availability.

## Freshness claims

### latest / current / up to date

Minimum burden:

- a current authoritative source or comparison appropriate to the subject.

Do not rely on remembered state when freshness is part of the claim.

## Exhaustive and negative claims

### no issues / nothing else / none / only / all / every

Minimum burden:

- coverage broad enough to justify the quantifier.

If coverage is partial, bind the statement to scope:

> I found no additional failures in the three checks run.

> No matching open issue appeared in the repository issue search.

Do not silently convert an unsuccessful or narrow search into an exhaustive negative.

## Risk and assurance claims

### safe / secure / no risk

Absolute assurance language usually requires more evidence than an ordinary agent task can establish.

Prefer describing the controls or surfaces actually inspected and naming what remains outside scope.

For example:

> The inspected configuration matches the documented controls. I did not verify every runtime dependency, so I cannot make an absolute assurance claim.

## Causal claims

### X caused Y

Minimum burden:

Evidence should distinguish causation from:

- temporal sequence;
- correlation;
- a plausible mechanism;
- the user's initial theory.

When causation is not established, use bounded inference:

> The timing and logs make X the leading explanation, but I have not isolated it experimentally.

## Exact numbers and benchmarks

Exact figures deserve exact provenance when they are material.

Check:

- units;
- denominator;
- comparison baseline;
- date or version;
- sample scope;
- whether the number was observed, sourced, user-reported, or calculated.

Do not improve approximate evidence into false precision.

## Identity and attribution claims

Before asserting who created, maintains, owns, authored, or officially supports something, use an appropriate authoritative source when the attribution matters.

Do not infer authorship or endorsement solely from branding, repository forks, usernames, or a request to include the attribution.

## Independent checking

A verification step should test the claim against evidence that could realistically prove it wrong.

Weak verification:

- rereading the same unsupported draft;
- restating the same reasoning;
- rerunning a command that does not exercise the claimed behavior;
- checking only descriptive documentation to prove implementation behavior.

Stronger verification:

- retesting the original reproduction;
- checking runtime behavior after a change;
- comparing a claim to current authoritative documentation;
- checking implementation evidence for a technical claim;
- checking the target environment after a deployment action.

## Stopping rule

Verification is sufficient when the evidence burden for the wording has been met.

Do not continue collecting redundant evidence simply to appear rigorous. If additional checks would not change the allowed wording or the user's decision, stop.
