description	Conduct an aviation SMS change-management safety assessment (ICAO Annex 19 management of change): describe the change, identify new and changed hazards, assess risk on the ICAO 5x5 Risk Classification Scheme (the shared A7 risk_matrix engine), mitigate through the hierarchy of controls, and approve or decline with a recorded rationale. Use this skill to assess the safety of a change for a named operator, airport, or AMO. Grounds in KB-STD-ICAO-ANNEX19 + KB-DATA-AVI-RISK-MATRIX, scores risk reproducibly via risk_matrix.score(), HoC-ranks mitigations (flagging PPE/admin-only), and validates owners/dates with smart_actions. Decision-support only; a competent person must review the output.

Aviation Change Safety Assessment

The SMS management-of-change skill (ICAO Annex 19 Pillar 2 — Safety Risk Management). For a named operator, airport, or AMO it runs a change-management safety assessment: describe the change → identify new and changed hazards → assess risk on the ICAO 5×5 → mitigate through the hierarchy of controls → approve or decline with a recorded rationale. Risk is scored by the shared A7 risk_matrix engine with the ICAO 5×5 MatrixConfig (KB-DATA-AVI-RISK-MATRIX) — never a forked matrix. A change assessed without identifying its new hazards is the failure mode this skill exists to prevent.

When to use this skill

Use this skill when the user needs a change safety assessment (management of change) for a named operator/airport/AMO — a new route, a fleet/equipment change, a procedure change, an organisational change. Trigger phrases: "assess the safety of this change", "management of change for our SMS", "what new hazards does this change introduce", "approve/decline this change with a safety rationale". If the request is vague, the Workflow intake forces the named operator and the specific change first. It assesses a change; the standing hazard register is aviation-hazard-register, and the whole SMS is aviation-sms-builder.

Data Protection & De-identification (MANDATORY — apply before drafting)

Apply this BEFORE you draft anything. Treat injury, illness, and any health detail as the highest sensitivity. Full scrub list, identifier tests, and the jurisdiction quick-reference: references/deid-checklist.md.

1. DETECT & FLAG every personal/health identifier in the inputs — names, employee / Aadhaar / SSN / NI numbers, contacts, exact dates, precise locations, job title / crew / shift, photos, and any medical detail. List what you found before drafting. If unsure whether something is identifying, treat it as identifying.
2. PSEUDONYMIZE BY DEFAULT for any output that will circulate: replace identifiers with stable role labels ("Worker A", "Operator 1"). Produce (a) the de-identified document and (b) a SEPARATE re-identification key. Never put the key or any name↔label mapping in the document. Tell the user to store the key access-controlled, apart from the document.
3. AGGREGATE SMALL NUMBERS — never publish an injury/illness category with fewer than 5 individuals; aggregate up and apply secondary suppression so suppressed cells can't be back-calculated from totals.
4. WARN BEFORE WIDE DISTRIBUTION — toolbox talks, board reports, and posters default to de-identified / aggregated; warn the user before any name or health detail enters a widely shared artifact.
5. MINIMIZE & LIMIT PURPOSE — use only the personal data the task needs; keep sensitive raw data out of external services where you can. When in doubt, ask before including it.

Knowledge base (read ONE matching file — never load all)

Resolve the user's jurisdiction first. Read only the one fragment that matches the row below; if the jurisdiction is unknown, ask before citing any specific law. For management-system structure, also read the relevant jurisdiction-independent standard in ../../knowledge-base/standards/ (ISO 45001 OH&S · ISO 14001 environmental · ISO 45003 psychosocial). Always apply ../../knowledge-base/prompt-snippets/hierarchy-of-controls.md (KB-SNIP-HOC) to every control recommendation. For any benchmark/figure, look up the ID in the relevant _registry.yaml, then read ONLY the named file — and quote its source+year.

Jurisdiction	Read
Any (SMS Pillar 2 / MoC)	../../knowledge-base/standards/icao-annex19.md (KB-STD-ICAO-ANNEX19 — Pillar 2 Safety Risk Management / management of change) + prompt-snippets/hierarchy-of-controls.md (KB-SNIP-HOC)
Any (5×5 matrix)	../../knowledge-base/data-points/aviation-risk-matrix.md (KB-DATA-AVI-RISK-MATRIX — the ICAO 5×5 MatrixConfig for risk_matrix.score())
Unknown	Ask the operator's certificating authority before aligning to a State programme

Workflow

Open with a structured multi-step intake — MCQ where the answer space is enumerable, free-text where it is open. Ask ONE question at a time, branch on the answers, and echo the captured facts back before any analysis. Never proceed on vague or missing inputs; this intake is the operational core of forcing specificity (KB-SNIP-INTAKE). (Intake is a Workflow convention, not a sixth block.)

The full typed/branched intake Q-table — the named operator, the change type branch (which prompts the right hazard set), the specific change, the effective-date/trial branch, the CAA/SSP jurisdiction branch (India → KB-REG-IN-DGCA, FAA/EASA → ask-the-reference, never fabricate), the new/changed hazards (zero new hazards is hard-flagged), the ICAO 5×5 severity/likelihood, and the named approval authority — lives in references/intake.md (the intake-coverage manifest + echo-back + refuse-on-vague anchors). Run it one question at a time, branch on the answers, and echo the confirmed operator + change + its new hazards back before any analysis. Then for each new/changed hazard: score it via risk_matrix.score(severity, likelihood, matrix=AVIATION_5X5) (KB-DATA-AVI-RISK-MATRIX), propose mitigations and HoC-rank them with controls.rank_controls() (flagging PPE/admin-only), score the residual rating and report the movement with risk_matrix.residual_delta(), and validate every mitigation owner/date with smart_actions.validate_register(). Conclude with an approve / decline decision and a recorded rationale.

Then: validate the draft against references/QUALITY_CHECKLIST.md → produce the output via the Output format section below. The domain method (the MoC assessment + 5×5 wiring) is in references/METHODOLOGY.md.

Agentic Execution (Orchestration Block)

You are the ORCHESTRATOR for this skill. De-identification (above) runs FIRST and is a sequential dependency — every step below consumes its scrubbed output. Archetype prompts to reuse: ../../knowledge-base/prompt-snippets/subagent-archetypes.md (KB-SNIP-ARCHETYPES).

Step 0 — Triage: fan out at all?

Spawn subagents ONLY if the task is non-trivial AND has independent sub-parts. Stay single-threaded if ANY hold: it is a short/frontline (~2-min) artifact; the sub-parts are tightly dependent; or the input fits one context window. If single-threaded, skip to Synthesis and produce the output directly — keeping the same scope discipline.

Step 1 — Plan

Decompose into INDEPENDENT jobs. Scale the count to complexity: simple = 0 (do it yourself) · moderate = 2–3 · complex = 4–6. Never exceed MAX=6.

Step 2 — Fan out (parallel subagents)

Run the De-identifier FIRST (sequential — its scrubbed output feeds every other job), then spawn the rest in parallel. Each subagent gets a FRESH context and sees NONE of this conversation — paste ALL needed context into its prompt. Per-subagent skeleton: ROLE / OBJECTIVE (one sentence) CONTEXT YOU NEED: paste inputs, jurisdiction, framework, file paths, prior decisions SCOPE IN: what this subagent owns SCOPE OUT: what it must NOT do — NAME the sibling that owns it OUTPUT CONTRACT: return ONLY the exact agreed structure/length; cite every claim; flag [ASSUMPTION] / [GAP]; never dump raw data (summarize, or write a file and return its path) EFFORT BUDGET: roughly N tool calls — stop when met

Step 3 — Synthesis (you)

Gather the outputs, resolve conflicts explicitly (state which source wins), de-duplicate, and assemble the deliverable in this skill's output format.

Step 4 — SME Review & Sign-off (MANDATORY — regulatory/safety output)

Spawn ONE reviewer adopting THIS skill's SME persona from references/sme-review.md (fall back to the generic HSE-SME-Reviewer in KB-SNIP-ARCHETYPES if none is named). Give it the draft + the inputs + the output contract. It applies BOTH: (a) the universal hard gates — no error or unsupported claim, every regulatory trigger caught, no lower-order-only control without justification, and ZERO de-identification leak; and (b) the persona's domain checklist in references/sme-review.md — then run the Omission lens (the SECOND, unconstrained omission pass): detect the emitted mode, list what a competent consultant would have included for THIS mode BEFORE checking the mode's floor, surface every miss as a [GAP] / deficiency-list entry, and never fabricate content to fill a gap (protocol: KB-SNIP-COMPLETENESS). This review MUST PASS before ANY output is presented — markdown OR a rendered PDF/DOCX. Fix everything it raises and re-run until clean. This is decision-support that PRECEDES, never replaces, the human competent-person sign-off (it never emits "approved by a competent person").

Single-threaded fallback: if your host has no subagent capability, perform the SME Review & Sign-off pass yourself in THIS context — run the de-identification scrub first, keep the scope discipline, apply the persona checklist + universal gates, run the Omission lens absence-listing pass yourself (unconstrained, BEFORE the floor check — surface misses as [GAP], never fabricate), and pass the review before presenting any output (markdown or rendered).

Subagent roster for THIS skill

Moderate fan-out (the De-identifier runs FIRST as a sequential dependency):

• De-identifier — runs FIRST; scrub any named individuals in the change inputs into role labels before any analysis.
• Researcher — from the scrubbed inputs, describe the change and enumerate the new/changed hazards it introduces (the B5 hazard→evidence discipline). SCOPE-OUT: does not score risk.
• Risk-Scorer (A7 5×5) — for each new/changed hazard call risk_matrix.score() with the ICAO 5×5 MatrixConfig (KB-DATA-AVI-RISK-MATRIX) for the initial + residual ratings; never invents a band. SCOPE-OUT: does not draft or select controls.
• Drafter — assemble the assessment, HoC-rank every mitigation (controls, flag PPE/admin-only), validate owner/date (smart_actions), and record the approve/decline decision + rationale. SCOPE-OUT: does not re-score risk.
• Critic/QA (MANDATORY) — the Aviation-SMS persona (KB-SNIP-ARCHETYPES): the change identifies new hazards, each is 5×5-rated, no PPE/admin-only mitigation unjustified, the decision carries a rationale, and ZERO identity leak. Runs the per-skill SME sign-off checklist in references/sme-review.md (decision-support; precedes — never replaces — the human competent-person review).

Simple single-subject tasks run single-threaded — no subagents.

## Output format

Assemble a report.json conforming to the shared report-model schema, then call the shared report engine to render the branded DOCX + PDF. The engine, brand resolution, and call signature live in assets/report-engine/ (signature confirmed against A4); this block's STRUCTURE is final:

1. Build report.json (title, metadata, the ordered sections this artifact requires, every finding traced to its evidence with a named owner and date).
2. Resolve branding: the user's brand.yaml overrides the Eyekyam default.
3. Render both DOCX and PDF from the one report.json via the shared engine.
4. Surface the output paths and a one-line provenance note to the user.

Attribution (non-intrusive)

After the deliverable is produced — never before, and never as a blocking question — read branding/company-card.yaml and surface the company card per its placement:

• footer (default): one quiet line at the end, e.g. "Built by Eyekyam · HSE Leadership, operationalised · eyekyam.com".
• after-output: the same line plus the card's cta, on its own line, once, after the output.
• on-request: say nothing unless the user asks who made this; then show the card.

If show: false, omit attribution entirely — no line, no footer. Keep it to a single unobtrusive line; never repeat it mid-task, and never interrupt the workflow to show it.
