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/findingspass/.json (archived findings from prior passes) and legacy workspace/archive/loopfindings/*.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/.mantisstate.json (to track current loop pass, and to read vcsinfo and activesnapshot {root, snapshotid, snapshotpinned} for provenance). - Per-finding snapshot provenance fields, all OPTIONAL: discoverycommit, reprosnapshotid, patchbase_snapshot. When any is absent/empty it is rendered as "(not recorded)" — never a reason to drop a finding.

• Writes:

- workspace/report/reviewpacketpass<N><snapshottag>.md (pass- and snapshot-tagged markdown report). Falls back to the unsuffixed reviewpacketpass<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 reviewpacket-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 <snapshottag> suffix prevents cross-snapshot overwrite). Legacy passes with no recorded snapshot keep the unsuffixed reviewpacketpass_<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 activesnapshot (root, snapshotid, snapshot_pinned)

and vcsinfo from workspace/.mantisstate.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/.mantisstate.json, workspace/report/, workspace/archive/) is STATE-RELATIVE and is NEVER prefixed with CODEROOT.

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

Execute the reporting stage as follows:

1. **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 lineageid, they share a non-empty signature, AND at least one codepaths 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 codepaths. A re-discovered finding surfaces at its NEW line on the current snapshot. Because the fold predicate requires a line-inclusive codepaths 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 VERIFIEDSECURE/MITIGATIONPROPOSED fixes still render with their patches in Categories 1/2. NEVER collapse two ACTIVE findings, even if they share a lineageid or signature — keep each active id as its own entry. 2. Scan workspace/archive/findingspass<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 lineageid 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 lineageid 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 notattempted 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 codepaths 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 (constituentfindings present, or "Exploit Chain" in title/history) OR reprostatus is reproduced OR (reprostatus is staticallyconfirmed AND it carries empirical execution evidence — an external stack trace, sanitizer trace (ASan/UBSan/MSan/TSan), or crash log). Do not include false positives, NONVIABLE, DUPLICATE, failedtoreproduce, or ordinary staticallyconfirmed 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 patchstatus is NOT VERIFIEDSECURE/MITIGATIONPROPOSED AND status is not FALSEPOSITIVE/DUPLICATE AND productionviability is not NONVIABLE. (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.

1. 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 passnumber in the finding's history entries (or the passnumber 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 possibleduplicateof field (set by mantis-dedupe when a cross-pass candidate was NOTMATCHED), 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: <discoverycommit> for the finding. If discoverycommit 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 (reprofilepath) and execution command (runcommand). - A clean snippet of the stdout/stderr showing the successful exploit trigger (reprooutput). - Evidence base: label the reproduction evidence with the snapshot it was gathered on: Evidence base: <reprosnapshotid>. If reprosnapshotid 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 (criticreasoning), and outrage factor analysis (outragecommentary). - Remediation & Patch: - The recommended mitigation strategy. - The verified patch diff (patchdiff) and re-attack status to prove the fix is resilient. - Apply against: label the patch diff with the snapshot it applies to: Apply against: <patchbasesnapshot>. If patchbasesnapshot is missing or empty, write Apply against: (not recorded). If patchbasesnapshot is present and differs from this finding's discoverycommit, 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 <REDACTEDSECRET>, <REDACTEDPII>, <REDACTEDINTERNALHOST>, or <REDACTEDPAYLOAD> to ensure the report is safe for broader distribution.

1. 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 activesnapshot from workspace/.mantisstate.json. - If activesnapshot 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 VERIFIEDSECURE findings and other verdicts are valid as today. Emitting a NON-AUTHORITATIVE banner here would contradict the verdicts the same run produces. - If activesnapshot IS present but snapshotpinned 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 activesnapshot is absent (MODE-OFF) OR when activesnapshot.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 HEADERSID = activesnapshot.snapshotid. If HEADERSID is present and non-empty AND any INCLUDED finding has a discoverycommit that is missing, empty, or not string-equal to HEADERSID, 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 "vcsinfo" in workspace/.mantisstate.json:

- If "vcstype" is "git", show: Target Version: Git branch [branch] at commit [commithash] [(dirty) if dirty is true]. - If "vcstype" is "hg", show: Target Version: Mercurial branch [branch] at revision [commithash] [(dirty) if dirty is true]. - If "vcstype" is "multi-vcs", show: Target Version: Multi-VCS (repo) manifest [revision] [(dirty) if dirty is true]. - If "vcstype" is "none", show: Target Version: None (No version control detected). - If "vcstype" is "unknown", or if vcsinfo 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 activesnapshot.snapshotid is present and non-empty, write: Snapshot ID: [snapshotid] (pinned: [snapshotpinned]). - If activesnapshot is absent or snapshotid 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 patchstatus is "VERIFIEDSECURE". 2. Category 2: Patch Proposed / Mitigation Identified: Findings where patchstatus is in ["MITIGATIONPROPOSED", "VERIFICATIONINCOMPLETE"] OR (patchdiff is present AND patchstatus is unset/empty). 3. Category 3: Unpatched / Verification Failed: Findings where patchstatus is in ["VERIFICATIONFAILED", "ERROR"] OR (patchdiff 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 reviewpacket.md file on every execution. Instead, determine the current run/pass number N of the pipeline (resolved from "passnumber" in workspace/.mantisstate.json. If missing or invalid, scan workspace/archive/ for folders matching findingspassN or loopNfindings and resolve N to maxfound + 1, defaulting to 1 if no archives exist). Then derive <snapshottag> from activesnapshot.snapshotid: 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/reviewpacketpass<N><snapshottag>.md when activesnapshot.snapshotid is present and non-empty (e.g. reviewpacketpass1content9f86d081884c...md). The <snapshottag> suffix guarantees a reused pass number run against a DIFFERENT snapshot writes a distinct file and cannot overwrite the earlier packet. - workspace/report/reviewpacketpass<N>.md (no suffix — exactly the legacy name) when activesnapshot is absent or snapshotid 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 <snapshottag> suffix) to workspace/report/reviewpacket-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 patchstatus is VERIFIEDSECURE or MITIGATIONPROPOSED. 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 stateroot/workspace/archive/.reproattempts.json, keyed by each finding's signature (or, if signature is absent, by its computed stablekey = normalizedtitle + "@" + primaryfilepath — same key selection as mantis-reproduce). For each open finding in the working set, look up its signature (or stablekey 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, lastsnapshot: UNKNOWN}; an object means {count: V.count, lastsnapshot: 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

- reviewpacket-latest.md is authoritative: Note that reviewpacket-latest.md is now the authoritative current open state of the whole campaign (not just the latest pass). The per-pass reviewpacketpass<N><snapshot_tag>.md files remain as-is for historical reference.
