claude-sense-check

claude-sense-check is a skill for Claude Code from joris887/exosuit. It costs 29 tokens per session (1,314 once invoked), scanned A, original, MIT.

A code-based logic check for user-acceptance tests. It traces selected test cases through the source code without running the tests with a user.

In plain words
What is it for?
Finding unchecked UAT cases, grouping related cases, tracing their relevant modules and user flows, and recording completed sense checks.
Why use it?
It identifies logical gaps early and keeps track of which acceptance scenarios have been checked from the code perspective.

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

claude-sense-check 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 11d 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.

claude-sense-check

Performing incremental Claude Sense Check on UAT backlog.

Phase 1: Read Current State

  1. Find the UAT tracking file: check for docs/testing/UAT_COVERAGE.md, docs/testing/UAT_INDEX.md, or docs/testing/uat/ directory
  2. Scan for Claude Sense Check sections in every test case
  3. Build a work queue: cases where - [ ] Logic verified from code perspective is unchecked
  4. Skip cases where the checkbox is already [x]
  5. If all cases are checked, report "All UAT cases have been sense-checked" and stop

Phase 2: Pick Next Batch

From the unchecked cases, sorted by priority (critical > high > medium > low), then by ID within each priority level:

  1. Select 2-5 cases that share the same module, feature area, or user flow
  2. Present to the user:
    • Batch: which cases (e.g., UAT-005, UAT-006, UAT-007)
    • Area: the functional area they belong to
    • Rationale: why they belong together
    • Relevant files: source files and components expected to be involved
  3. Proceed after presenting (no user confirmation needed — this is a code-only check)

Phase 3: Gather Context

Before checking any logic, collect the full picture for the batch's feature area:

  1. Read all source files relevant to the batch
  2. Trace the data flow for the feature area end-to-end
  3. Note dependencies, shared state, API contracts, and external integrations
  4. Read existing tests for the relevant code — they reveal intent and edge cases
  5. Check the Covers field on each test case to identify which backlog stories are involved
  6. Read the story acceptance criteria from the relevant epic/backlog file

Do NOT proceed to logic checks until you have the full picture.

Phase 4: Code Logic Check (per case)

For each case in the batch:

  1. Read the test case steps and acceptance criteria carefully
  2. Trace each step through the actual source code
  3. For each acceptance criterion, verify:
    • The code path exists and is reachable
    • Conditionals are correct (no off-by-one, no inverted logic)
    • Data flows correctly between components
    • Error handling covers the expected failure modes
    • Edge cases mentioned in the test case are handled
  4. Assign a verdict with confidence (high = full code path traced, medium = partial trace or complex logic, low = inference without full trace):
    • Pass (high/medium/low) — logic is correct, code handles the scenario properly
    • Warning (high/medium/low) — potential issue found, describe with file:line reference
    • Fail (high/medium/low) — confirmed broken, describe with file:line reference and root cause

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.
