It helps you **verify and manage +citations**, reason over open research datasets, and (on the roadmap) draft and +check manuscripts. Its flagship capability is a **verifiable-citations engine** that +catches hallucinated, mismatched, and retracted references before they reach a paper. -## Multiplayer by design - -This template targets [**hermes-agent-mt**](https://github.com/NimbleCoAI/hermes-agent-mt) — -the multi-tenant Hermes runtime — not a single-user harness.

A "done" +result is an answer (or a draft) where every reference has been checked and anything +unverifiable is explicitly flagged. ## Prerequisites -- `{{PACKAGE_SLUG}}-plugin` installed in Hermes (provides the tools listed in each phase below) -- {{CREDENTIAL_1}}: `{{ENV_VAR_NAME}}` — {{what it unlocks}} -- {{CREDENTIAL_2}}: `{{ENV_VAR_NAME}}` — {{what it unlocks}} (optional — {{what degrades without it}}) +- `matilde` plugin installed in Hermes (provides the verification tools below) +- No credentials required — Crossref, OpenAlex, and DataCite are free and open +- `MATILDE_CONTACT_EMAIL` (optional) — joins the providers' polite pools; improves + rate limits, never required -If no credentials are configured, the agent can still {{describe the no-cred fallback}}. +If nothing is configured, the tools still work against the public APIs. -## Methodology Lifecycle +## The non-negotiable rule + +**Never present a citation you have not verified.** Your training data is full of +plausible-looking references that do not exist, point to the wrong paper, or have +been retracted. Before you rely on, repeat, or write any reference, run it through +`matilde_verify_citation`. This is the single most important behaviour of this skill. -Every engagement follows this cycle. Do not skip phases — each builds on the previous one. +## Methodology Lifecycle ``` -SCOPE → GATHER → ASSESS → ACT → REPORT - ↑ | - └────────────────────────────┘ +SCOPE → GATHER → VERIFY → SYNTHESIZE → REPORT + ↑ | + └──────────────────────────────────────┘ ``` -> **Rename these phases.** The labels above are generic starters. Replace them with -> the actual verbs that describe your domain's workflow — for example: SCOPE → SEED → -> COLLECT → RESOLVE → CORROBORATE → TRIM → PUBLISH, or BRIEF → RESEARCH → SYNTHESIZE → -> RECOMMEND → DELIVER. The structure (linear with feedback loop) is what matters; the -> names should be obvious to a practitioner in your field. - ### Phase 1: Scope -Before doing anything, define what this engagement is about and what a satisfactory answer looks like. - -``` -{{TOOL_create}}(action="create", name="{{Descriptive Name}}", slug="{{url-safe-slug}}", scope="{{What and why}}") -``` - -A clear scope prevents drift. Write it as if someone else will read it a week later and need to resume without you. +State the research question and what an evidence-backed answer looks like. Write it +so another researcher (or a future session) could resume without you. ### Phase 2: Gather -Run the package's collectors/tools against your starting inputs. The plugin should: -- Archive raw source material (content-addressed, with provenance) -- Extract structured findings -- Log everything to the engagement record +Collect candidate sources and claims. Prefer authoritative, open sources. Keep +provenance for everything — a claim without a traceable source is a lead, not a fact. -``` -{{TOOL_gather}}(engagement_slug="...", source="{{source_name}}", query="{{input}}") -``` +### Phase 3: Verify (the core) -### Phase 3: Assess - -After initial gathering, assess what you have: what's well-supported, what's missing, what contradicts. +Run every citation through the four-axis check: ``` -{{TOOL_assess}}(engagement_slug="...", action="gaps") -{{TOOL_assess}}(engagement_slug="...", action="summary") +matilde_verify_citation(doi="10.1038/...", title="...", authors=["..."], year=2017, url="...") ``` -Look for: -- Single-source findings that need corroboration -- Contradictions between sources -- High-confidence items that are still under-explored +The verdict is one of: -### Phase 4: Act (Targeted Work) +- **`verified`** — exists, metadata matches, not retracted, URL (if any) resolves. Safe to use. +- **`warnings`** — exists, but something is off (year/author mismatch, dead URL, low metadata match). Inspect the per-axis detail; fix the reference or note the discrepancy. +- **`retracted`** — the work has been retracted. **Do not cite it as sound.** If you must mention it, mark it as retracted. +- **`not_found`** — the DOI/title does not resolve in Crossref, OpenAlex, *or* DataCite. Treat as **likely fabricated** until proven otherwise. +- **`unverifiable`** — not enough information to check (e.g. no DOI and an ambiguous title). Get more identifying detail. -Based on the assessment, take targeted action: fill gaps, expand confirmed threads, prune noise. +For a whole reference list, use the batch tool — it returns a summary and the +indices that most need attention: -**Fill a gap:** -``` -{{TOOL_gather}}(engagement_slug="...", source="{{targeted_source}}", query="{{gap_query}}") ``` - -**Prune noise below a confidence threshold:** +matilde_verify_bibliography(references=[{doi: "..."}, {title: "...", authors: ["..."]}, ...]) ``` -{{TOOL_trim}}(engagement_slug="...", threshold={{0.0_to_1.0}}) -``` - -This hides low-confidence findings without deleting them. Reversible. -**Expand a confirmed finding outward:** -Run all relevant collectors against the identifiers of a well-confirmed finding. This is how work grows outward from anchored nodes. - -### Phase 5: Report - -Generate the deliverable in the format appropriate for the engagement. +For a fast retraction-only check by DOI: ``` -{{TOOL_report}}(engagement_slug="...", format="{{json|markdown|csv|pdf}}") -{{TOOL_report}}(engagement_slug="...", format="markdown", min_confidence={{threshold}}) +matilde_check_retraction(doi="10.1016/...") ``` -## Iteration Pattern - -Good work in this domain is iterative, not linear. The standard loop: - -1. **Gather** from known starting points -2. **Assess** — identify gaps and contradictions -3. **Fill gaps** — targeted gathering on weak areas -4. **Prune** — remove noise below confidence threshold -5. **Expand** — follow confirmed leads outward -6. **Repeat** until the gap analysis returns no actionable items at your target confidence level, or until the scope question is answered - -An engagement is "done" when you can answer the scope question with evidence that meets your delivery standard, or when you've documented why the question cannot be answered with available sources. - -## Novelty / Don't Redo Work - -When an engagement is approaching its deliverable, run novelty checks **in parallel with -gathering** — not after. Spawn parallel subagents: one gathering and synthesizing a -thread, one checking whether the key claims are already covered by prior work, existing -reports, or public sources. - -This stops you from investing deeply in threads that are already fully handled elsewhere. - -For each key claim or finding, determine: - -1. Has this already been addressed — by a prior engagement, a public source, or an existing artifact? -2. If yes — do we have something genuinely additional that constitutes a meaningful contribution? -3. If no — is our sourcing strong enough to stand alone? - -Track each claim's novelty in one of three buckets: - -- **Already covered** — do not lead with these as new. Reference the prior work instead. -- **Partially covered / gap** — possible angles; nail down what specifically is new before committing effort. -- **Potentially original** — verify carefully before treating as confirmed. Check secondary and niche sources, not just the obvious ones: a finding in a low-circulation source is still "known." +**Interpreting axes honestly.** A `verified` verdict means *checked against +authoritative metadata* — existence, identity, retraction status. It does **not** +mean the cited passage actually supports the claim it is attached to. That deeper +check (claim-support grounding) is not yet automated; when it matters, read the +source and confirm the passage yourself, and say that you did. -A finished deliverable is **grounded in evidence, novel relative to prior work, and tells -a story a non-specialist would find actionable.** +### Phase 4: Synthesize -## Session Continuity: The Handoff Pattern +Assemble verified material into an argument or analysis. Carry confidence levels +through — distinguish "well-established (multiple verified sources)" from "suggested +by a single source" from "unverified." -Long, multi-session engagements need explicit continuity infrastructure. The agent cannot -hold working state across sessions natively — this discipline is what replaces it. - -Three layers carry state across sessions: - -- **Standing-orders document** — what this engagement is, what it values, what the - current working hypothesis is. Read it at the start of every session. This is - engagement-specific and lives in the operator's private overlay (`skills/` in - `HERMES_HOME`), **not** in this shared package. See the extension-point section below. -- **Memory layer** — accumulated findings, resolved questions, and tool quirks kept in - the agent's persistent memory and in per-engagement reference files. -- **Handoff artifact** — a structured end-of-session summary written by the outgoing - session, read first by the incoming session. - -### What a Handoff Carries +### Phase 5: Report -A handoff is not a log dump. It is a cold-start entry point. Write it so a fresh session -can resume in under two minutes without re-deriving everything. A complete handoff -contains: +Deliver the answer or draft with: +- a reference list where **every entry has been verified**, and +- an explicit "could not verify" section for anything that came back `not_found`, + `retracted`, `unverifiable`, or `warnings` you could not resolve. -- **What happened and why** — a brief narrative of what the session did and the - reasoning behind the key moves. Not a transcript; a digest. -- **Decisions with rationale** — every non-obvious decision made this session, with the - reason. "I chose source X over Y because..." Future sessions must be able to evaluate - whether the reason still holds. -- **State per active thread** — for each open line of work: where it stands, what was - last done, and what the concrete next step is (specific enough to execute without - context). -- **Open threads with next steps** — explicitly enumerated, each with a next action. Not - "look into X" but "run {{TOOL_gather}} against {{specific_identifier}} to close the gap - on {{specific_claim}}." -- **Closed threads with reasons** — what was explored and set aside, and why. Prevents - the next session from re-opening dead ends. -- **Cold-start entry point** — a single instruction the incoming session can execute - immediately to get oriented: read a specific artifact, run a specific tool call, - check a specific status. If the next session has to read the full handoff to know - where to start, the handoff is too long. +## Iteration Pattern -Update the handoff at the end of any significant session with: novelty-assessment -changes, new thread status, methodology lessons, and tool quirks discovered. The same -discipline the evidence trail provides for facts, applied to the engagement's own working -state. +1. **Gather** candidate sources +2. **Verify** them — drop or flag anything `not_found`/`retracted` +3. **Fill gaps** — find better sources for weak or unverifiable claims +4. **Expand** — follow verified sources outward (their references, citing works) +5. **Repeat** until the question is answered with verified evidence, or you have + documented why it cannot be ## Quality and Ethics Floor -These apply regardless of domain.
