Reporter (/mantis-report)

System Goal

Security Reporting Expert. Synthesizes complex, technical finding logs into a high-quality, human-readable review packet for developers and stakeholders.

Command Definition

Command:
```
/mantis-report
```
Description: Generates a human-readable security review packet containing confirmed findings and exploit chains.

Input/Output Contract

Reads:
- ```
workspace/findings/*.json
```
  (all active finding files for this pass).
- ```
workspace/archive/findings_pass_*/*.json
```
  (archived findings from prior passes) and legacy
```
workspace/archive/loop*_findings/*.json
```
  . The report is a campaign-wide view: this pass's full findings plus carried-forward findings that prior passes stopped retrying (e.g. hit the retry cap) so they do not vanish from the report.
- ```
workspace/.mantis_state.json
```
  (to track current loop pass, and to read
```
vcs_info
```
  and
```
active_snapshot
```
  {
```
root
```
  ,
```
snapshot_id
```
  ,
```
snapshot_pinned
```
  } for provenance).
- Per-finding snapshot provenance fields, all OPTIONAL:
```
discovery_commit
```
  ,
```
repro_snapshot_id
```
  ,
```
patch_base_snapshot
```
  . When any is absent/empty it is rendered as "(not recorded)" — never a reason to drop a finding.
Writes:
- ```
workspace/report/review_packet_pass_<N>_<snapshot_tag>.md
```
  (pass- and snapshot-tagged markdown report). Falls back to the unsuffixed
```
review_packet_pass_<N>.md
```
  on a legacy pass with no recorded snapshot.
- Updates copy/symlink at
```
workspace/report/review_packet-latest.md
```
  .
Preconditions:
- Calibrated and reproduced findings exist in
```
workspace/findings/
```
  or
```
workspace/archive/
```
  . The report is a campaign-wide view: it reports the current state of every unresolved finding discovered in this or any prior pass, de-duplicated to each finding's latest state. A confirmed-but-unfixed finding that plan stopped carrying back (e.g. it hit the 2-attempt retry cap) does NOT vanish — it appears here at its most recent archived state.
Idempotency Guarantee:
- Writes to pass-and-snapshot-tagged files. In-place overwrite of
```
review_packet-latest.md
```
  . Re-running the SAME pass on the SAME snapshot updates the same tagged file. Re-running the same pass number on a DIFFERENT snapshot writes a DISTINCT file (the
```
<snapshot_tag>
```
  suffix prevents cross-snapshot overwrite). Legacy passes with no recorded snapshot keep the unsuffixed
```
review_packet_pass_<N>.md
```
  name and overwrite in place, exactly as before.

Instructions

Step 0 — Locator Resolution.

LOCATOR RESOLUTION (before reading ANY target code or artifact):
0. ROLE: If this skill NEVER reads target source (report, calibrate, reflect),
   you are a FINDINGS-ONLY stage: skip steps 2-6; still read active_snapshot from
   state for provenance/annotation; NEVER stop merely because a code root is unset.
1. Determine CODE_ROOT, in this priority order:
   a. If --target_root is passed on THIS invocation, CODE_ROOT = --target_root.
      It is AUTHORITATIVE and OVERRIDES SNAPSHOT_ROOT and the state fallback
      (used when a caller hands you a prepared tree, e.g. a patched shadow).
   b. Else if --snapshot_root (or SNAPSHOT_ROOT) is passed, use it.
   c. Else read state_root/workspace/.mantis_state.json (state_root from
      --state_root if passed, else ./workspace/... relative to the current dir)
      -> active_snapshot.root / .snapshot_id / .snapshot_pinned.
   d. Else (no arg AND no readable active_snapshot): CODE_ROOT = current directory,
      treat snapshot_pinned = false (MODE-OFF). Do NOT stop.
2. SENTINEL CHECK (only if snapshot_pinned is true AND you did NOT take path 1a):
   verify CODE_ROOT/.mantis_snapshot_id exists and equals SNAPSHOT_ID. If missing
   or different -> STOP "snapshot sentinel mismatch". (A --target_root tree (1a) is
   deliberately mutated and is sentinel-EXEMPT.)
3. PATH FIELDS:
   - SNAPSHOT-RELATIVE (read under CODE_ROOT): code_paths entries; plan target_files
     that are file paths. Strip ONLY a trailing ":<digits>". A code_paths entry
     containing "://" is a URL/endpoint, NOT a file read. A code_paths entry that is
     NOT of the form <existing-path>:<integer> is a non-source LOCATOR
     (symbol/offset/endpoint): only check that the artifact/symbol exists; skip ALL
     line-range and line-existence logic.
   - STATE-RELATIVE (read/write under state_root/workspace, NEVER prefix CODE_ROOT):
     kb_references, repro_file_path, reattack_file_path, helper scripts, report
     files, and all state/findings JSON.
4. Never WRITE under CODE_ROOT when snapshot_pinned is true. Any command that
   compiles, generates, or writes artifacts MUST run in a PRIVATE SHADOW copy
   (mktemp -d from CODE_ROOT), never with cwd=CODE_ROOT. Read-only inspection may
   cd into CODE_ROOT.
5. VCS-METADATA CARVE-OUT: history-log extraction and any VCS diff/blame command
   run in the LIVE repository root (which still has .git/.hg/.repo), NOT CODE_ROOT
   (the snapshot copy strips VCS metadata). Do NOT stop merely because CODE_ROOT
   lacks .git/.hg/.repo.
6. Every shell command uses ABSOLUTE paths and sets its own working directory on
   that call. Do NOT assume the working directory persists between calls.

Then the following FINDINGS-ONLY notes apply to the Reporter:

The Reporter is a FINDINGS-ONLY stage (Block A, ROLE step 0): it SKIPS locator steps 2–6, does NOT require or resolve a CODE_ROOT, and NEVER stops because a code root or sentinel is unset.
It STILL reads
```
active_snapshot
```
(
```
root
```
,
```
snapshot_id
```
,
```
snapshot_pinned
```
) and
```
vcs_info
```
from
```
workspace/.mantis_state.json
```
for provenance — used to build the header, the top banners, and the output file name.
Every path the Reporter touches (
```
workspace/findings/*.json
```
,
```
workspace/.mantis_state.json
```
,
```
workspace/report/*
```
,
```
workspace/archive/*
```
) is STATE-RELATIVE and is NEVER prefixed with CODE_ROOT.

Compile a professional Markdown report detailing the verified/reproduced vulnerabilities and exploit chains.

Execute the reporting stage as follows:

Load findings — this pass in full, plus carried-forward open findings (newest-first fold; no script). Build a working set keyed by finding identity, each finding once at its most-recent state:
SAME-BUG PREDICATE (used for ALL current↔archived dedup, fold, and suppression in this stage; over-reporting is always safe here, hiding a real finding is never acceptable): two findings are the SAME BUG only if EITHER (i) they have the exact same
```
id
```
(UUID); OR (ii) ALL THREE hold — they share a non-empty
```
lineage_id
```
, they share a non-empty
```
signature
```
, AND at least one
```
code_paths
```
entry compared WITH its trailing
```
:line
```
(line-inclusive) is identical between them. Otherwise they are DISTINCT — render BOTH. NEVER treat two findings as the same bug on
```
lineage_id
```
alone or
```
signature
```
alone: both are coarser than a bug's true identity (basename-derived lineage can link two distinct same-named files; a
```
signature
```
strips the line number so it collides between distinct same-file bugs), and collapsing on either alone can silently drop a real finding.
Design note (re-anchoring vs fold):
```
mantis-plan
```
's re-anchoring (Phase 2) only provides a line hint that steers RE-DISCOVER — it does NOT rewrite the carried finding's
```
code_paths
```
. A re-discovered finding surfaces at its NEW line on the current snapshot. Because the fold predicate requires a line-inclusive
```
code_paths
```
match, the re-discovered finding will NOT fold with its ancestor (the line numbers differ). This is SAFE over-reporting — both entries render, the current one shows the new location. A future phase could relax the predicate to path-only matching when BOTH findings carry the same
```
signature
```
AND
```
lineage_id
```
AND the ancestor's line is confirmed absent on the current snapshot, but the conservative line-inclusive match is used today to prevent any silent-drop risk.
1. Read all active
```
workspace/findings/*.json
```
  and add every active finding to the working set, keyed by its
```
id
```
  (UUID) — all remediation statuses, so this pass's
```
VERIFIED_SECURE
```
  /
```
MITIGATION_PROPOSED
```
  fixes still render with their patches in Categories 1/2. NEVER collapse two ACTIVE findings, even if they share a
```
lineage_id
```
  or
```
signature
```
  — keep each active
```
id
```
  as its own entry.
2. Scan
```
workspace/archive/findings_pass_<N>/
```
  (and legacy
```
loop<N>_findings/
```
  ) in descending pass order. Add an archived finding only if it is still OPEN (see 4) AND NO finding already in the working set is the SAME BUG as it (per the predicate above) AND no earlier (higher-pass) archived copy of the SAME BUG was already added. First copy met = latest state; ignore later same-bug copies in lower dirs. (An archived finding is suppressed ONLY when a genuine same-bug supersedes it; a mere
```
lineage_id
```
  or
```
signature
```
  coincidence does NOT suppress it.)
3. Supersession fold (Phase 3): When an archived finding IS the SAME BUG (predicate ii) as a current finding, the current finding supersedes it — show a single entry at the current (most-recent) state; do not also render the archived copy. When the predicate is NOT satisfied (different
```
signature
```
  , e.g. a file rename, or
```
lineage_id
```
  absent), render both as separate entries (safe over-reporting, never hiding).
  - Under-reporting safeguard: If the current (superseding) finding FAILS the actionable predicate (step 4 below) but the archived ancestor would have PASSED it (e.g., the ancestor was
    reproduced
    and OPEN, but the current pass's reproduce resulted in
    not_attempted
    due to a transient build/environment failure on the new snapshot), do NOT let the transient downgrade suppress the confirmed-open bug. Instead, keep the ancestor's last confirmed state visible in the report (render it with a note "Open — repro pending on new snapshot") so a previously-confirmed bug can never silently disappear from the report. The current finding's newer metadata (e.g., updated
    code_paths
    line numbers) may still be attached as an annotation, but the verdict/status shown must be the ancestor's last confirmed state, never the transient downgrade.
4. Actionable / quality predicate (applies to active AND archived): include a finding only if it is an exploit chain (
```
constituent_findings
```
  present, or "Exploit Chain" in title/history) OR
```
repro_status
```
  is
```
reproduced
```
  OR (
```
repro_status
```
  is
```
statically_confirmed
```
  AND it carries empirical execution evidence — an external stack trace, sanitizer trace (ASan/UBSan/MSan/TSan), or crash log). Do not include false positives,
```
NON_VIABLE
```
  ,
```
DUPLICATE
```
  ,
```
failed_to_reproduce
```
  , or ordinary
```
statically_confirmed
```
  findings lacking empirical traces.
5. Open predicate (archived carry-forward in step 2 only): an archived finding is "still open" if it satisfies (4) AND
```
patch_status
```
  is NOT
```
VERIFIED_SECURE
```
  /
```
MITIGATION_PROPOSED
```
  AND
```
status
```
  is not
```
FALSE_POSITIVE
```
  /
```
DUPLICATE
```
  AND
```
production_viability
```
  is not
```
NON_VIABLE
```
  . (Active findings are loaded regardless of
```
patch_status
```
  so this pass's fixes still appear; archived fixed findings are not re-listed every pass — use the optional "Resolved this campaign" rollup for a cumulative fixed view.)
6. Scale: process one directory at a time, newest-first; never load the whole archive at once.
- Severity Filtering: Exclude findings with a priority of
```
"LOW"
```
  from the main report body. You must place these lower-priority issues into a separate, dedicated "Appendix: Low Priority Findings" section at the very end of the report, keeping the main report focused on high-risk issues.
Extract Key Artifacts: For each reproduced finding, extract and format:
- Header Metadata: Title, ID (UUID), Inferred Exposure, Final Risk Score, and Qualitative Priority.
- Campaign Provenance: Annotate each open finding with the pass it was first discovered in vs. the current pass (e.g.
```
discovered pass 2 · still open as of pass 7
```
  ), so carried-over findings are visible as such. First-seen = the lowest
```
pass_number
```
  in the finding's
```
history
```
  entries (or the pass_number of the lowest-numbered archive dir that contains it); current state = the copy you kept from the fold above.
- Duplicate Advisory: If the finding has a
```
possible_duplicate_of
```
  field (set by
```
mantis-dedupe
```
  when a cross-pass candidate was NOT_MATCHED), emit an advisory note:
```
Possibly related to finding <UUID> (cross-pass candidate; snapshots differ — not confirmed duplicate).
```
  This makes the advisory regression-pointer visible to the stakeholder.
- Discovery Snapshot: Emit
```
Discovery Snapshot: <discovery_commit>
```
  for the finding. If
```
discovery_commit
```
  is missing or empty, emit
```
Discovery Snapshot: (legacy — not recorded)
```
  . Never omit or drop the finding because this field is absent.
- Vulnerability Description & Impact: A clear explanation of the bug and the concrete impact on the system.
- Reproduction Evidence:
  - The PoC script path (
    repro_file_path
    ) and execution command (
    run_command
    ).
  - A clean snippet of the stdout/stderr showing the successful exploit trigger (
    repro_output
    ).
  - Evidence base: label the reproduction evidence with the snapshot it was gathered on:
    Evidence base: <repro_snapshot_id>
    . If
    repro_snapshot_id
    is missing or empty, write
    Evidence base: (not recorded)
    . Do NOT assume it equals the header/pass snapshot.
- Risk Rationale: The independent validation reasoning (
```
reasoning
```
  ), production viability reasoning (
```
critic_reasoning
```
  ), and outrage factor analysis (
```
outrage_commentary
```
  ).
- Remediation & Patch:
  - The recommended mitigation strategy.
  - The verified patch diff (
    patch_diff
    ) and re-attack status to prove the fix is resilient.
  - Apply against: label the patch diff with the snapshot it applies to:
    Apply against: <patch_base_snapshot>
    . If
    patch_base_snapshot
    is missing or empty, write
    Apply against: (not recorded)
    . If
    patch_base_snapshot
    is present and differs from this finding's
    discovery_commit
    , add a one-line caution that the diff was generated against a different snapshot and may not apply cleanly to the discovery snapshot.
- PII & Secrets Redaction: Before writing any finding data (including description, PoC script/command, and reproducer logs) to the report, you must scan and redact any hardcoded API keys, tokens, credentials, PII (names, emails, phone numbers), internal hostnames/domain names, and overly weaponized payload parameters, replacing them with standard placeholders like
```
<REDACTED_SECRET>
```
  ,
```
<REDACTED_PII>
```
  ,
```
<REDACTED_INTERNAL_HOST>
```
  , or
```
<REDACTED_PAYLOAD>
```
  to ensure the report is safe for broader distribution.
Generate Review Packet:
- Report Header & Disclaimer: At the very top of the report (before the Executive Summary):
  
  Snapshot provenance banners — emit these BEFORE item 1 below, at the very top of the report, each as its own separated blockquote, in this order:
  a. Non-authoritative / HALT banner (3-state rule). Read
  active_snapshot
  from
  workspace/.mantis_state.json
  . - If
  active_snapshot
  is absent (MODE-OFF — no
  --sync
  was requested, today's default): do NOT emit this banner. The run is byte-for-byte today's behavior; the report's
  VERIFIED_SECURE
  findings and other verdicts are valid as today. Emitting a NON-AUTHORITATIVE banner here would contradict the verdicts the same run produces. - If
  active_snapshot
  IS present but
  snapshot_pinned
  is
  false
  (HALT mode): emit as the FIRST line of the report:
  > **WARNING — NON-AUTHORITATIVE RESULTS:** The target could not be pinned to an immutable snapshot for this pass (HALT mode: the tree raced or was too big / live / copy-failed). Findings may not correspond to a stable, reproducible tree, and the ABSENCE of findings in this report does NOT indicate the target is secure. Treat all results as provisional.
  Omit this banner when
  active_snapshot
  is absent (MODE-OFF) OR when
  active_snapshot.snapshot_pinned
  is
  true
  (PINNED).
  b. Dirty working tree warning. If
  vcs_info.dirty
  is
  true
  , emit:
  > **WARNING — DIRTY WORKING TREE:** The target had uncommitted local modifications when it was scanned. Results reflect that exact working tree (captured by content hash), NOT a clean committed revision. The recorded commit alone will not reproduce this state.
  c. Mixed-snapshot banner. Let HEADER_SID =
  active_snapshot.snapshot_id
  . If HEADER_SID is present and non-empty AND any INCLUDED finding has a
  discovery_commit
  that is missing, empty, or not string-equal to HEADER_SID, emit:
  > **WARNING — MIXED SNAPSHOTS:** This report combines findings discovered on different code snapshots (e.g. findings retried from earlier passes). The pass snapshot is <HEADER_SID>. Consult each finding's "Discovery Snapshot" before acting; line numbers and code context may differ between snapshots.
  Compare snapshot IDs as EXACT strings only — no fuzzy or prefix match.
  1. Display the target codebase version information read from
    "vcs_info"
    in
    workspace/.mantis_state.json
    :
    - If
      "vcs_type"
      is
      "git"
      , show:
      Target Version: Git branch [branch] at commit [commit_hash] [(dirty) if dirty is true]
      .
    - If
      "vcs_type"
      is
      "hg"
      , show:
      Target Version: Mercurial branch [branch] at revision [commit_hash] [(dirty) if dirty is true]
      .
    - If
      "vcs_type"
      is
      "multi-vcs"
      , show:
      Target Version: Multi-VCS (repo) manifest [revision] [(dirty) if dirty is true]
      .
    - If
      "vcs_type"
      is
      "none"
      , show:
      Target Version: None (No version control detected)
      .
    - If
      "vcs_type"
      is
      "unknown"
      , or if
      vcs_info
      is missing, show:
      Target Version: Unknown (VCS detection failed/error)
      .
    After the
    Target Version:
    line, append the pass snapshot identity on a second line:
    - If
      active_snapshot.snapshot_id
      is present and non-empty, write:
      Snapshot ID: [snapshot_id] (pinned: [snapshot_pinned])
      .
    - If
      active_snapshot
      is absent or
      snapshot_id
      is empty, write:
      Snapshot ID: (legacy — snapshot not recorded)
      . This is display-only provenance; it does not gate or drop any finding.
  2. Include a prominent disclaimer note stating: “This report was automatically generated by Mantis AI. All findings and patches are AI-generated and must be manually verified by a security or subject matter expert before deployment or disclosure.”
- Grouping by Patch Status (Exclusivity): Organize the Executive Summary table and the main body of the report by grouping findings. Exploit chains MUST be excluded from these main groups and reported ONLY in their dedicated "Exploit Chains (Not End-to-End Reproduced)" section. For standard (non-chain) findings, group them into three distinct categories based on their remediation status (strictly mutually exclusive):
  1. Category 1: Patch Independently Verified: Findings where
    patch_status
    is
    "VERIFIED_SECURE"
    .
  2. Category 2: Patch Proposed / Mitigation Identified: Findings where
    patch_status
    is in
    ["MITIGATION_PROPOSED", "VERIFICATION_INCOMPLETE"]
    OR (
    patch_diff
    is present AND
    patch_status
    is unset/empty).
  3. Category 3: Unpatched / Verification Failed: Findings where
    patch_status
    is in
    ["VERIFICATION_FAILED", "ERROR"]
    OR (
    patch_diff
    is not present AND
    patch_status
    is unset/empty).
- Dedicated Exploit Chains Section: Create a dedicated section titled
  "Exploit Chains (Not End-to-End Reproduced)"
  specifically for exploit chains. Document each chain finding here, listing its title, qualitative priority, risk score, and detailing its constituent findings (their IDs and individual status). Do not mix exploit chains with standard findings in Categories 1, 2, or 3.
- Pass-Numbered Output: Do not overwrite the same
  review_packet.md
  file on every execution. Instead, determine the current run/pass number
  N
  of the pipeline (resolved from
  "pass_number"
  in
  workspace/.mantis_state.json
  . If missing or invalid, scan
  workspace/archive/
  for folders matching
  findings_pass_N
  or
  loopN_findings
  and resolve
  N
  to
  max_found + 1
  , defaulting to 1 if no archives exist). Then derive
  <snapshot_tag>
  from
  active_snapshot.snapshot_id
  : take the snapshot ID exactly as stored and replace every character NOT in
  [A-Za-z0-9.-]
  with a single underscore
  _
  (do NOT truncate — the result stays well under any filename length limit). Write the report to:
  - workspace/report/review_packet_pass_<N>_<snapshot_tag>.md
    when
    active_snapshot.snapshot_id
    is present and non-empty (e.g.
    review_packet_pass_1_content_9f86d081884c...md
    ). The
    <snapshot_tag>
    suffix guarantees a reused pass number run against a DIFFERENT snapshot writes a distinct file and cannot overwrite the earlier packet.
  - workspace/report/review_packet_pass_<N>.md
    (no suffix — exactly the legacy name) when
    active_snapshot
    is absent or
    snapshot_id
    is empty, preserving today's backward-compatible behavior.
- Latest Copy/Symlink: After writing the pass-numbered report above, update a symlink or write a copy of THAT exact file (whether or not it carries a
  <snapshot_tag>
  suffix) to
  workspace/report/review_packet-latest.md
  , so the latest version is always reachable. The
  review_packet-latest.md
  name is unchanged and remains the stable entry point for any downstream consumer.
- Use clean, professional Markdown formatting with clear headers, tables for metadata, and syntax-highlighted code blocks for logs and diffs.
- Include a high-level Executive Summary table at the top listing all included findings, their priority, and their risk scores.
- Optional sections (recommended):
  - Resolved this campaign: A short rollup using the same fold, but filtering to findings where
    patch_status
    is
    VERIFIED_SECURE
    or
    MITIGATION_PROPOSED
    . This gives stakeholders a visible "what got fixed" view alongside the open findings.
  - Unresolved — retry cap reached: A callout listing open findings whose reproduction attempt count is at the cap. The count is NOT a field on the finding JSON; it lives in the cache file
    state_root/workspace/archive/.repro_attempts.json
    , keyed by each finding's
    signature
    (or, if
    signature
    is absent, by its computed
    stable_key
    =
    normalized_title + "@" + primary_file_path
    — same key selection as
    mantis-reproduce
    ). For each open finding in the working set, look up its
    signature
    (or
    stable_key
    fallback) in that cache; include the finding in this callout if the cached value is at the retry cap. Read the cached value per the schema's value-shape rule: a bare integer V means
    {count: V, last_snapshot: UNKNOWN}
    ; an object means
    {count: V.count, last_snapshot: V.last_snapshot or UNKNOWN}
    . If the cache file is missing or the finding's key is absent, treat its count as 0 (do not list it here). These are items the planner stopped carrying
[!NOTE] De-dup caveat: de-dup is by finding identity, per the SAME-BUG PREDICATE at the top of this stage: two findings fold only if EITHER (i) they share the exact same
id
(UUID), OR (ii) ALL THREE hold — a shared non-empty
lineage_id
, a shared non-empty
signature
, AND at least one line-inclusive
code_paths
match. NEVER fold on
lineage_id
alone or on
signature
alone (basename-derived lineage can link two distinct same-named files; a
signature
strips the line number so it collides between distinct same-file bugs) — collapsing on either alone can silently drop a real finding. A bug re-discovered under a new UUID that does NOT satisfy predicate (ii) — a regression, a file rename that shifts the line, or a non-deterministic re-find — lists as a SEPARATE entry from its archived ancestor: over-reporting (safe), never hiding. With stable finding signatures and lineage tracking landed (Phase 3), a re-discovered finding folds into its ancestor's single entry ONLY when predicate (ii) is fully satisfied; the UUID-only match remains the safe branch for legacy/un-upgraded findings.
- review_packet-latest.md
  is authoritative: Note that
```
review_packet-latest.md
```
  is now the authoritative current open state of the whole campaign (not just the latest pass). The per-pass
```
review_packet_pass_<N>_<snapshot_tag>.md
```
  files remain as-is for historical reference.
