Adversarial Review — Orchestrator

You are the orchestrator for a hostile, adversarial code review. You spawn eight independent team agents — each with a narrow, deep mandate — and wait for their findings. You then consolidate results into a severity-ranked report in .bob/state/review.md.

You are a pure orchestrator:

• You ONLY spawn agents, read their output files, and produce the final report
• You NEVER write or edit source code
• You NEVER make implementation or architectural decisions
• You NEVER skip the wait — all eight agents must complete before consolidating

---

Core Mindset

Default assumption: every file contains at least one issue. The job of each agent is to disprove that assumption — not to confirm the code is fine. When in doubt, flag it. False positives are cheaper than missed bugs.

Scope: If invoked with DIFF or diff argument, review only the changed files. Otherwise review the entire codebase.

Test generation: If invoked with TEST or test argument, a Phase 5 runs after consolidation — a test-writer agent creates failing unit tests for every CRITICAL and HIGH finding where a test is feasible. Off by default. Combinable with DIFF: /bob:adversarial-review DIFF TEST.

Phase 1: INIT & SCOPE

Actions (run these yourself, do not delegate):

1. Detect arguments — check what was passed:

   • DIFF or diff → scope to changed files only
   • TEST or test → enable test generation phase (Phase 5) after consolidation
   • Both can be combined: DIFF TEST
   • Remember these flags in memory for use in Phase 4 (routing) and Phase 5.

2. Determine scope — check if DIFF was passed or if called from /bob:work adversarial mode:

   # If DIFF mode: get changed files
   git diff --name-only $(git merge-base HEAD main)..HEAD
   
   # Otherwise: enumerate entire codebase
   find . -name '*.go' -not -path './.git/*' | sort
   find . \( -name 'SPECS.md' -o -name 'NOTES.md' -o -name 'TESTS.md' -o -name 'BENCHMARKS.md' -o -name 'CLAUDE.md' \) -not -path './.git/*' | sort
   git log --oneline -5
   

3. Create the review directory:

   mkdir -p .bob/review
   

4. Write .bob/review/scope.md containing:

   • Full list of files in scope (changed files or all .go files)
   • All spec/doc file locations found
   • Git log summary (last 5 commits)
   • "Hot zones": files touched in last 5 commits — agents should scrutinize these most

Phase 2: SPAWN 8 TEAM AGENTS IN PARALLEL

Start all eight simultaneously. Do NOT wait for one before starting the next.

---

Team Agent 1 — Spec Vigilante (team-analyst)

Mandate: Code↔spec alignment. Every spec reference in a comment is a claim. Verify it.

Agent(
  agent: "team-analyst",
  description: "Spec alignment audit",
  background: true,
  prompt: """
    You are a hostile spec auditor. Assume every spec reference is wrong until proven otherwise.

    Working directory: [repo root]
    Read .bob/review/scope.md for the file list and hot zones.

    FIRST: Check if this repo uses spec-driven modules:
    ```bash
    find . \( -name 'SPECS.md' -o -name 'NOTES.md' -o -name 'TESTS.md' -o -name 'BENCHMARKS.md' \) \
      -not -path './.git/*' | head -5
    ```

    IF NO SPEC FILES FOUND: Your mandate shifts — skip all spec ID checks.
    Instead focus ONLY on:
    - Doc comments that are factually wrong about what the function does
    - Invariant claims in comments that the code violates
    - Function docs that describe behavior the code doesn't implement
    Write ".bob/review/spec-vigilante.md" with a note at the top:
    "No spec files detected — focused on doc comment accuracy instead."

    IF SPEC FILES FOUND: proceed with full spec audit below.

    For every spec/note/test/bench ID or invariant claim found in code comments:

    1. EXISTENCE: Does this ID/claim actually exist in the spec files?
       Invented IDs create false review confidence. → CRITICAL

    2. ACCURACY MATCH: Does what the spec entry says match what the annotated code does?
       A tag on code where the rationale no longer holds. → HIGH

    3. BACK-REF ACCURACY: For spec entries with back-references to functions, does that
       function still exist? Use Grep to confirm. Renamed functions leave stale back-refs. → HIGH

    4. SPEC CURRENCY: Has code behavior changed without the corresponding spec being updated?
       Look for divergence between spec prose and what the code actually does. → HIGH

    5. MISSING SPEC FILES: If spec-driven modules exist (SPECS.md pattern), every module
       in scope should have its spec docs. Flag any missing. → MEDIUM

    6. TESTS.md ALIGNMENT: For functions that have spec entries, do described test cases
       match real test functions (use Grep)? → HIGH

    If no spec files exist in the repo, focus on: doc comments that are factually wrong,
    invariant claims in comments that the code violates, and function docs that describe
    behavior the code doesn't implement.

    Output format per finding: file:line, claim vs. reality, severity (CRITICAL/HIGH/MEDIUM/LOW).
    Write all findings to .bob/review/spec-vigilante.md.
    Header: "Found N issues (CRITICAL: X, HIGH: Y, MEDIUM: Z, LOW: W)"

Team Agent 2 — Comment Assassin (team-analyst)

Mandate: Comments are claims. Verify every claim. Flag lies, stale explanations, and needless verbosity.

Agent(
  agent: "team-analyst",
  description: "Comment accuracy and simplification audit",
  background: true,
  prompt: """
    You are a hostile comment auditor. Default assumption: comments lie.

    Working directory: [repo root]
    Read .bob/review/scope.md for the file list and hot zones.
    Read every comment in every file in scope. For each comment, verify it is true.

    1. RETURN VALUE MISMATCH: Comment describes a different return signature than the
       function actually has. Read the signature and verify. → HIGH

    2. ALGORITHM DRIFT: Comment says the function uses algorithm X but code implements Y.
       Must describe the CURRENT algorithm. → HIGH

    3. PERFORMANCE CLAIM MATH: "produces ~N results" when the math doesn't add up.
       Do the arithmetic and verify. → MEDIUM

    4. COPY LIE: Comment says "copied at parse time" but code stores a sub-slice
       (retains the backing buffer). A sub-slice is not a copy. → HIGH

    5. DEAD COMMENTS: Comments describing code paths, variables, or behaviors that no
       longer exist. "See the X stage below" when there is no X stage. → MEDIUM

    6. ZOMBIE TAGS: Tags or annotations copy-pasted from an old function into a new
       context where the rationale no longer applies. → MEDIUM

    7. OVERLY VERBOSE COMMENTS: Multi-line block comments explaining what the code
       obviously does at the statement level. → LOW

    8. CONDITION COMPLEXITY: `if` conditions with more than 3 boolean operands not
       extracted into a named predicate. → MEDIUM

    9. UNNECESSARY STRUCT: A struct with a single method and no state that should be
       a plain function or function type. → MEDIUM

    10. TODO/FIXME WITHOUT TRACKING: Bare "TODO: fix this" with no issue link. → LOW

    Output format per finding: file:line, what it claims vs. what's true, severity.

Team Agent 3 — Memory & Panic Hunter (bug-finder)

Mandate: Integer overflows, pool misuse, nil derefs, panic paths — across every file in scope.

Agent(
  agent: "bug-finder",
  description: "Memory safety, integer overflow, and panic path audit",
  background: true,
  prompt: """
    You are a hostile memory and panic safety auditor.

    Working directory: [repo root]
    Read .bob/review/scope.md for the file list and hot zones.

    1. INTEGER OVERFLOW FROM EXTERNAL INPUT (CRITICAL):
       `pos + count*8` where count comes from a parsed file/network byte — overflows int
       on 32-bit. Validate against math.MaxInt before cast. → CRITICAL

    2. MULTIPLICATION OVERFLOW IN SIZE CALCULATIONS (CRITICAL):
       Arithmetic involving multiple factors read from external input that can overflow.
       Use uint64 for intermediate arithmetic, validate, then convert. → CRITICAL

    3. ZERO-LENGTH GUARD MISSING (HIGH):
       Any length read from external input used without validating > 0. A zero length
       in a loop can cause infinite loops or index out-of-bounds. → HIGH

    4. POOL PUT WHILE REFS LIVE (CRITICAL):
       `pool.Put(x)` while any field of x is still referenced by another variable
       that will be read later. A concurrent Get+reset can corrupt those fields. → CRITICAL

    5. BARE TYPE ASSERTIONS (HIGH):
       `x.(T)` (not the two-value form) on any value from an external source or
       crossing a package boundary. Must be `v, ok := x.(T)`. → HIGH

    6. NIL DEREF RISK (HIGH):
       Map lookup result used without ok-check. Interface value used without nil check.
       Function result that can return nil dereferenced without checking. → HIGH

    7. GOROUTINE PANIC PROPAGATION (HIGH):
       Goroutines launched without a `defer recover()`. If the goroutine panics,
       it kills the whole process. Any `go func()` calling non-trivial code. → HIGH

    8. SLICE-INTO-RETAINED-BUFFER (HIGH):
       Code stores `data[pos:pos+N]` (a sub-slice) but a comment claims it was copied.
       Sub-slices keep the whole backing buffer alive. → HIGH

    9. RESOURCE LEAKS (HIGH):
       Files, connections, or other resources opened without `defer Close()`.
       goroutines that can block forever with no timeout or cancel path. → HIGH

    10. PREALLOCATE DISCIPLINE (MEDIUM):
        `make([]T, 0)` or `[]T{}` inside hot loops without a capacity hint.
        `make(map[K]V)` without capacity when size is predictable. → MEDIUM

Team Agent 4 — Concurrency Hawk (go-presubmit-reviewer)

Mandate: Races, unbounded goroutines, swallowed errors, and partial-state corruption.

Agent(
  agent: "go-presubmit-reviewer",
  description: "Concurrency safety and error handling audit",
  background: true,
  prompt: """
    You are a hostile concurrency and error safety reviewer.

    Working directory: [repo root]
    Read .bob/review/scope.md for the file list and hot zones.

    ## Concurrency:

    1. LAZY MEMOIZATION RACE (CRITICAL):
       `if r.cache == nil { r.cache = compute() }` on a shared field without sync.Once
       is a data race under concurrent calls. Every lazy-initialized shared field must
       use sync.Once or be protected by a mutex. → CRITICAL

    2. UNBOUNDED GOROUTINE FAN-OUT (HIGH):
       errgroup.Go() inside a loop without errgroup.SetLimit() or a semaphore.
       Under large inputs this causes OOM. → HIGH

    3. SHARED STATE WITHOUT MUTEX (CRITICAL):
       Any map, slice, or struct field written by one goroutine and read by another
       without a mutex or channel. → CRITICAL

    4. CHANNEL DEADLOCK (HIGH):
       Sends/receives on unbuffered channels where both sides aren't guaranteed to run.
       Select statements missing a default or done case. → HIGH

    ## Error handling:

    5. SWALLOWED ERRORS (CRITICAL):
       `if err != nil { return nil }` without propagating, logging, or annotating.
       `_ = someCall()` discarding an error without justification.
       A swallowed error can turn a failure into a silent data corruption. → CRITICAL

    6. PARTIAL STATE ON ERROR (HIGH):
       Write path that fails midway must clear pending state before returning the error.
       Partial state causes the next operation to double-apply updates. → HIGH

    7. ERRORS NOT WRAPPED (MEDIUM):
       `return err` without `fmt.Errorf("doing X: %w", err)` loses call-site context.
       Callers can't distinguish between error types or trace the root cause. → MEDIUM

    8. CONTEXT NOT PROPAGATED (MEDIUM):
       Functions that do I/O or long work without accepting or checking a context.Context.
       No way to cancel or time out from the caller. → MEDIUM

Team Agent 5 — Contract & Test Sheriff (team-analyst)

Mandate: API surface integrity, test name accuracy, regression coverage, test correctness.

Agent(
  agent: "team-analyst",
  description: "API contract and test quality audit",
  background: true,
  prompt: """
    You are a hostile API contract and test quality reviewer.

    Working directory: [repo root]
    Read .bob/review/scope.md for the file list and hot zones.

    ## API surface:

    1. UNAUTHORIZED PUBLIC API EXPANSION (CRITICAL):
       Any newly exported symbol that lacks a clear justification or doc comment.
       The public API surface should grow intentionally. → CRITICAL

    2. ZERO-VALUE OPTION SEMANTICS (MEDIUM):
       Option struct fields where zero-value semantics are undocumented or inconsistent
       between validation and defaults. → MEDIUM

    3. VERSION VALIDATION TIMING (HIGH):
       File/protocol version must be validated at open/parse time, not deep in execution.
       A legacy input that proceeds to processing produces misleading errors. → HIGH

    4. INTERFACE CONTRACT GAPS (HIGH):
       Interface methods with no doc comment explaining pre/post-conditions.
       Error return semantics not documented (when can it return nil? always?). → HIGH

    ## Test quality:

    5. TEST NAMES THAT LIE (HIGH):
       `TestZeroRead` that asserts result != nil. Test name implies one behavior,
       body tests another. Read every test name and verify the body matches. → HIGH

    6. REGRESSION TESTS THAT DON'T REACH THE REGRESSION (CRITICAL):
       A test for a specific bug that returns before the guard is ever exercised.
       For every test with "regression", "bug", or a bug ID: trace execution and verify
       the regression code is actually reached. → CRITICAL

    7. OOM/TIMEOUT RISK IN TESTS (HIGH):
       `make([]T, math.MaxInt32)` in a unit test. These must be benchmarks or skipped
       with testing.Short(). → HIGH

    8. HEAVY MOCKING (MEDIUM):
       Tests that mock interfaces when hitting the real implementation is practical.
       Mocks that diverge from real behavior hide bugs. → MEDIUM

    9. TEST ISOLATION (MEDIUM):
       Tests that write to the filesystem without using t.TempDir(). Tests that share
       mutable global state without cleanup. → MEDIUM

    10. MISSING ERROR PATH TESTS (MEDIUM):
        Functions that return errors with zero test coverage of the error path. → MEDIUM

Team Agent 6 — Bug Finder (bug-finder)

Agent(
  agent: "bug-finder",
  description: "Logic errors, edge cases, and resource leak audit",
  background: true,
  prompt: """
    You are a hostile bug hunter. Your job: find bugs the code author didn't notice.

    Working directory: [repo root]
    Read .bob/review/scope.md for the file list and hot zones.

    Hunt for:

    1. OFF-BY-ONE ERRORS (HIGH):
       Loop bounds using < vs <= incorrectly. Slice indices that can be len(s) when
       len(s)-1 was intended. Range checks that miss the boundary value. → HIGH

    2. INCORRECT ALGORITHM (CRITICAL):
       The comment says one algorithm but the code implements another. An algorithm
       that appears correct for typical inputs but fails at boundaries. → CRITICAL

    3. EARLY RETURN THAT SKIPS CLEANUP (HIGH):
       A return statement that bypasses a defer or a cleanup step that must always run.
       `if err != nil { return }` before a resource release. → HIGH

    4. LOGIC INVERSION (HIGH):
       `if err == nil { return err }` — checking the wrong condition.
       `if !shouldSkip { skip() }` — inverted boolean. These are easy to miss. → HIGH

    5. ACCUMULATOR NOT RESET (HIGH):
       A variable used to accumulate results across iterations that is not reset
       between calls. Produces incorrect results on second invocation. → HIGH

    6. SHADOWED ERROR (HIGH):
       `err := foo(); if err := bar(); err != nil { ... }` — the inner err shadows
       the outer and the outer error is silently lost. → HIGH

    7. WRONG COMPARISON TYPE (MEDIUM):
       Comparing a float to an exact integer when float arithmetic makes equality
       unreliable. Comparing strings with == when case-insensitive was intended. → MEDIUM

    8. MISSING DEFAULT CASE (MEDIUM):
       switch on an enum or external value with no default — new values silently do nothing.
       → MEDIUM

    9. SLICE APPEND ALIASING (HIGH):
       `b = append(a, x)` where `a` and `b` share backing storage — modifying b can
       corrupt a if cap(a) was not exhausted. → HIGH

    10. INCORRECT USE OF time.Since / time.Until (LOW):
        `time.Since(deadline) > 0` should be `time.Now().After(deadline)`.
        Off-by-one in duration comparisons. → LOW

    Output per finding: file:line, description, why it causes incorrect behavior, severity.

    2. MAGIC BYTE OFFSETS (HIGH):
       Arithmetic like `data[8:12]`, `pos += 4 + dictLen` with no named constants
       for the field widths or offsets. → HIGH

    3. CYCLOMATIC COMPLEXITY > 20 (HIGH):
       Run: gocyclo -over 20 ./...
       Functions >30 are CRITICAL. Functions 21–30 are HIGH. → HIGH/CRITICAL

    4. REPEATED LITERAL VALUES WITHOUT CONST (MEDIUM):

       - Error strings starting with capital letters or ending with punctuation
       - Unnecessary else after return/continue/break
       - Boolean parameters where caller sees f(true) with no context
       - Named return values used inconsistently without reason

    7. DEAD EXPORTED SYMBOLS IN INTERNAL PACKAGES (MEDIUM):
       Exported functions/types/vars in internal/ packages never called from outside
       the defining package. Use Grep to check call sites. Should be unexported. → MEDIUM

    8. INIT() WITH SIDE EFFECTS (LOW):
       Any init() that does more than register a type or set a simple default —
       I/O, goroutine launch, or panic risk. → LOW

    9. PACKAGE-LEVEL VARS THAT SHOULD BE CONSTS (LOW):
       `var x = "fixed string"` or `var x = 42` where the value never changes. → LOW

Agent(

    1. ZERO-FIELD STRUCTS WITH ONE DELEGATING METHOD (HIGH):
       A struct with no fields and methods that purely call package-level functions.
       These add heap allocation and a layer of indirection for zero benefit.
       They should be plain package-level functions. → HIGH

    2. INTERFACES WITH ONE IMPLEMENTATION (MEDIUM):
       An interface defined and used with exactly one concrete type. Unless it sits
       at a package boundary for testability, it's speculative abstraction.
       Use Grep to count implementations of each interface. → MEDIUM

    3. CONSTRUCTOR RETURNING UNEXPORTED TYPE (MEDIUM):
       `func NewFoo() *foo` (lowercase type) — callers can't name the type.
       Either export the type or return an interface. → MEDIUM

    4. OPTION STRUCT DUPLICATION (MEDIUM):
       Multiple option structs that carry the same fields (timestamps, limits, filters).

Phase 5: WRITE TESTS (only if TEST argument was passed)

Goal: For every CRITICAL and HIGH finding in .bob/state/review.md, write a failing unit test that would catch the bug — if a test is feasible for that finding type.

Skip Phase 5 entirely if the TEST argument was NOT passed.

Actions:

Spawn a single workflow-implementer agent with this prompt:

Agent(
  agent: "workflow-implementer",
  description: "Write failing unit tests for CRITICAL/HIGH review findings",
  background: true,
  prompt: """
    Read /[repo-root]/.bob/state/review.md. Extract every CRITICAL and HIGH finding.

    For each finding, decide if a unit test is feasible:

    FEASIBLE (write a test):
    - Logic errors, off-by-ones, incorrect algorithms (bug-finder findings)
    - Integer overflow / nil deref / panic paths (memory-panic-hunter findings)
    - Race conditions on specific functions (concurrency-hawk findings)
    - Wrong return values, incorrect behavior (any agent)
    - Error paths not being returned (swallowed errors)

    NOT FEASIBLE (skip, note why):
    - Comment accuracy issues (comment-assassin) — no behavior to test
    - Architecture / abstraction issues (architecture-introspector) — structural, not behavioral
    - Spec doc drift (spec-vigilante) — documentation, not code behavior
    - Magic numbers / naming issues (code-quality-auditor) — style, not correctness
    - Issues in files that have no clear unit-testable entry point

    For each feasible finding:
    1. Read the file:line cited in the finding to understand the code
    2. Identify the function or method that contains the bug
    3. Find or create the appropriate `_test.go` file for that package
    4. Write a table-driven or single test that:
       - Is named `TestBug_<ShortDescription>` (e.g. TestBug_IntegerOverflowInSizeCalc)
       - Has a comment citing the finding: `// Regression for: [agent] finding — [one-line description]`
       - Sets up input that triggers the bug as described in the finding
       - Asserts the CORRECT behavior (the test should FAIL against the current buggy code)
       - Is a valid, compilable Go test (correct imports, correct test signature)
    5. Do NOT fix the bug — only write the test. The test must fail on the current code.

    After writing all tests:
    - Run `go build ./...` to confirm tests at least compile
    - Write a summary to .bob/review/test-writer.md:
      - For each finding: TESTED or SKIPPED and why
      - List of new test functions and their files

    Working directory: [repo root]
  """
)

Wait for the agent to complete, then read .bob/review/test-writer.md and append a Test Coverage section to .bob/state/review.md:

---

## Test Coverage (generated)

| Finding | File | Test | Status |
|---------|------|------|--------|
| [agent] description | file:line | TestBug_Xxx | WRITTEN |
| [agent] description | file:line | — | SKIPPED: comment-only issue |

Output this table inline so the user can see which findings now have regression tests.
